class=\"ez-toc-section\" id=\"How_to_Add_Custom_PHP_Code_to_WordPress\"><\/span>How to Add Custom PHP Code to WordPress<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress is built with PHP, which means PHP code can be used to extend the functionality of a website far beyond what is available through standard settings. Custom PHP can add new features, modify existing behavior, create custom shortcodes, change WordPress hooks, and automate certain tasks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, adding PHP code requires more care than adding CSS. A small syntax error can cause PHP errors or make parts of a website inaccessible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide explains several safe ways to add custom PHP code to WordPress and how to troubleshoot common problems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_Custom_PHP_in_WordPress\"><\/span>What Is Custom PHP in WordPress?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">PHP is the server-side programming language used by WordPress.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Custom PHP code can be used to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Create custom functions<\/li>\n\n\n\n<li>Add shortcodes<\/li>\n\n\n\n<li>Modify WordPress hooks<\/li>\n\n\n\n<li>Change default WordPress behavior<\/li>\n\n\n\n<li>Add custom post-processing<\/li>\n\n\n\n<li>Customize admin functionality<\/li>\n\n\n\n<li>Modify user roles and capabilities<\/li>\n\n\n\n<li>Integrate third-party services<\/li>\n\n\n\n<li>Add custom API functionality<\/li>\n\n\n\n<li>Automate repetitive tasks<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example, the following code creates a simple shortcode:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function my_custom_message() {\n    return 'Welcome to our website!';\n}\n\nadd_shortcode('custom_message', 'my_custom_message');<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">You could then use:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&#91;custom_message]<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">inside supported WordPress content areas.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Before_Adding_PHP_Code\"><\/span>Before Adding PHP Code<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">PHP can directly affect how WordPress operates, so take a few precautions first.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Create_a_Backup\"><\/span>Create a Backup<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Create a current backup of your website before making significant PHP changes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ideally, have backups of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>WordPress files<\/li>\n\n\n\n<li>Database<\/li>\n\n\n\n<li>Themes<\/li>\n\n\n\n<li>Plugins<\/li>\n\n\n\n<li>Uploaded media<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Test_on_a_Staging_Website\"><\/span>Test on a Staging Website<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If possible, test custom PHP on a staging website before deploying it to your production site.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Keep_Recovery_Access_Available\"><\/span>Keep Recovery Access Available<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Make sure you can access your hosting file manager, FTP\/SFTP, or another recovery method if a PHP error prevents normal WordPress administration.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Method_1_Use_a_Code_Snippets_Plugin\"><\/span>Method 1: Use a Code Snippets Plugin<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">For many WordPress websites, a dedicated snippets plugin is a convenient way to manage custom PHP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The general process is:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Log in to WordPress.<\/li>\n\n\n\n<li>Go to <strong>Plugins \u2192 Add New Plugin<\/strong>.<\/li>\n\n\n\n<li>Search for a reputable PHP snippets plugin.<\/li>\n\n\n\n<li>Install and activate it.<\/li>\n\n\n\n<li>Create a new PHP snippet.<\/li>\n\n\n\n<li>Paste your code.<\/li>\n\n\n\n<li>Save the snippet.<\/li>\n\n\n\n<li>Activate it.<\/li>\n\n\n\n<li>Test your website.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">This approach keeps custom code separate from your theme files.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It can also make individual snippets easier to disable when troubleshooting.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Method_2_Add_PHP_to_a_Child_Theme\"><\/span>Method 2: Add PHP to a Child Theme<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">If your custom code is specifically related to your theme, you can place it in the child theme&#8217;s:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>functions.php<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;?php\n\nfunction my_custom_message() {\n    return 'Welcome to my website!';\n}<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">If the child theme is already active, WordPress can load the child theme&#8217;s <code>functions.php<\/code> alongside the parent theme&#8217;s functionality.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Important\"><\/span>Important<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Don&#8217;t copy the entire parent theme&#8217;s <code>functions.php<\/code> into the child theme.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A child theme&#8217;s <code>functions.php<\/code> is not a replacement for the parent&#8217;s file. It is loaded in addition to it.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Method_3_Add_PHP_Through_a_Custom_Plugin\"><\/span>Method 3: Add PHP Through a Custom Plugin<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">For functionality that should remain active even when you change themes, creating a small custom plugin is often a better solution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Create a directory such as:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>wp-content\/plugins\/my-custom-functions\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Inside it, create:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>my-custom-functions.php<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Add a plugin header:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;?php\n\/*\nPlugin Name: My Custom Functions\nDescription: Custom functionality for this website.\nVersion: 1.0\n*\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">You can then add your custom code below the header.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;?php\n\/*\nPlugin Name: My Custom Functions\nDescription: Custom functionality for this website.\nVersion: 1.0\n*\/\n\nfunction my_custom_message() {\n    return 'Welcome to our website!';\n}\n\nadd_shortcode('custom_message', 'my_custom_message');<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Upload the plugin directory to:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>wp-content\/plugins\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Then go to:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>WordPress Dashboard \u2192 Plugins<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Find your custom plugin and activate it.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Method_4_Use_a_Hosting_File_Manager\"><\/span>Method 4: Use a Hosting File Manager<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">You can also add PHP code directly through your hosting control panel&#8217;s file manager.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Locate:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>public_html\/wp-content\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Then navigate to the appropriate theme or plugin directory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>public_html\/\n\u2514\u2500\u2500 wp-content\/\n    \u2514\u2500\u2500 themes\/\n        \u2514\u2500\u2500 my-child-theme\/\n            \u2514\u2500\u2500 functions.php<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Open the appropriate file and add your PHP code.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Be_Careful\"><\/span>Be Careful<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Don&#8217;t modify WordPress core files such as:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>wp-admin\/\nwp-includes\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">or individual files in the WordPress root unless you have a very specific reason and understand the consequences.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Core modifications can be lost during WordPress updates and can make maintenance more difficult.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Method_5_Use_FTP_or_SFTP\"><\/span>Method 5: Use FTP or SFTP<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">If you prefer working outside the hosting control panel, you can use an FTP\/SFTP client.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Connect to your hosting account and navigate to:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>wp-content\/themes\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">or:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>wp-content\/plugins\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Download the relevant file, edit it locally, and upload it again.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SFTP is generally preferable to unencrypted FTP when your hosting provider supports it.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Example_Add_a_Simple_WordPress_Function\"><\/span>Example: Add a Simple WordPress Function<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Here&#8217;s a basic example that displays a message in the site&#8217;s footer:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function my_footer_message() {\n    echo '&lt;p class=\"custom-footer-message\"&gt;Thank you for visiting our website.&lt;\/p&gt;';\n}\n\nadd_action('wp_footer', 'my_footer_message');<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">The <code>wp_footer<\/code> hook tells WordPress when to execute the function.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Understanding_WordPress_Hooks\"><\/span>Understanding WordPress Hooks<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Hooks are one of the most important concepts when adding custom PHP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress provides two major types of hooks:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Actions\"><\/span>Actions<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Actions allow you to execute your own code at a particular point.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function my_custom_action() {\n    \/\/ Custom code here\n}\n\nadd_action('wp_footer', 'my_custom_action');<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Filters\"><\/span>Filters<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Filters allow you to modify data before WordPress uses or displays it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function my_custom_title($title) {\n    return $title . ' | My Website';\n}\n\nadd_filter('the_title', 'my_custom_title');<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Filters should normally receive the data they&#8217;re filtering and return the modified value.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Example_Add_a_Shortcode\"><\/span>Example: Add a Shortcode<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">You can create a custom shortcode using:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function my_company_name() {\n    return 'Ehostpiya';\n}\n\nadd_shortcode('company_name', 'my_company_name');<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Then use:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&#91;company_name]<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">in supported WordPress content.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The shortcode will output:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Ehostpiya<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This can be useful for reusable content that appears in multiple places.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Example_Add_a_Custom_Admin_Message\"><\/span>Example: Add a Custom Admin Message<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress also provides hooks for the administration area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function my_admin_notice() {\n    echo '&lt;div class=\"notice notice-info\"&gt;&lt;p&gt;Custom website message.&lt;\/p&gt;&lt;\/div&gt;';\n}\n\nadd_action('admin_notices', 'my_admin_notice');<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This displays an informational notice in the WordPress administration area.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Use_Unique_Function_Names\"><\/span>Use Unique Function Names<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">When writing custom PHP, avoid generic function names such as:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function custom_function() {\n}<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Another plugin or theme could already use the same name.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead, use a unique prefix.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function ehostpiya_custom_function() {\n}<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">A unique prefix reduces the possibility of function-name collisions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Avoid_Editing_WordPress_Core_Files\"><\/span>Avoid Editing WordPress Core Files<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Never use WordPress core files as your normal location for custom PHP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, avoid adding custom functionality directly to:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>wp-includes\/\nwp-admin\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">or core PHP files in the WordPress root.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your custom code should generally live in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A custom plugin<\/li>\n\n\n\n<li>A snippets plugin<\/li>\n\n\n\n<li>A child theme<\/li>\n\n\n\n<li>Another appropriate custom extension<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This keeps your modifications separate from WordPress itself.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Handle_PHP_Errors\"><\/span>How to Handle PHP Errors<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">A PHP syntax error can cause a <strong>critical error<\/strong> or prevent certain pages from loading.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common mistakes include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Missing_Semicolon\"><\/span>Missing Semicolon<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Incorrect:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>$message = 'Hello'<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Correct:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>$message = 'Hello';<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Missing_Closing_Bracket\"><\/span>Missing Closing Bracket<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Incorrect:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function my_function() {\n    echo 'Hello';<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Correct:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function my_function() {\n    echo 'Hello';\n}<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Duplicate_Function_Names\"><\/span>Duplicate Function Names<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If two plugins or files declare the same function, PHP can generate a fatal error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use unique prefixes for custom functions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_to_Do_If_Custom_PHP_Breaks_the_Website\"><\/span>What to Do If Custom PHP Breaks the Website<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Don&#8217;t panic if a newly added snippet causes a critical error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First, identify the code you recently added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you used a snippets plugin, disable the problematic snippet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you added code to a child theme&#8217;s <code>functions.php<\/code>, use your hosting file manager or SFTP to edit the file and remove or correct the problematic code.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If WordPress provides a recovery mechanism or error details, use those details to identify the affected file and line.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always make a backup before making additional changes.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Enable_Debugging_for_Development\"><\/span>Enable Debugging for Development<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">For troubleshooting on a development or staging website, WordPress debugging can help identify PHP problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In <code>wp-config.php<\/code>, you can use:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>define('WP_DEBUG', true);\ndefine('WP_DEBUG_LOG', true);\ndefine('WP_DEBUG_DISPLAY', false);<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This configuration enables debugging and records errors in the WordPress debug log while preventing errors from being displayed directly to visitors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do not expose PHP error messages on a production website<\/strong>, because they can reveal sensitive technical information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After troubleshooting, review whether debugging should remain enabled.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Custom_PHP_vs_Custom_Plugin\"><\/span>Custom PHP vs Custom Plugin<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">A common question is whether code should go into <code>functions.php<\/code> or a custom plugin.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Requirement<\/th><th>Child Theme<\/th><th>Custom
