How To Print The $plugin_meta Array

Printing the $plugin_meta array is a common task for debugging or customizing plugin metadata in WordPress development. This guide explains how to output this array effectively.

Why Print the $plugin_meta Array?

Printing the $plugin_meta array allows developers to:

• Inspect plugin metadata for debugging purposes.
• Customize metadata displayed in the WordPress admin panel.
• Ensure compatibility with other plugins or themes.

Steps to Print the $plugin_meta Array

1. Locate the Plugin File:
   
   • Open the main PHP file of your WordPress plugin.
   • Ensure you have access to the plugin_row_meta filter hook.
2. Add a Custom Function:

Define a custom function to print the $plugin_meta array:
function print_plugin_meta($plugin_meta, $plugin_file, $plugin_data) {

    echo ‘<pre>’;

    print_r($plugin_meta);

    echo ‘</pre>’;

    return $plugin_meta;

}

3. Attach the Function to the Filter:
   

Use the add_filter function to hook your custom function:
add_filter(‘plugin_row_meta’, ‘print_plugin_meta’, 10, 3);

4. Test the Output:
   
   • Navigate to the “Plugins” section in your WordPress admin panel.
   • Look for the printed $plugin_meta array below the relevant plugin.
5. Format and Debug:
   
   • Use <pre> tags for readable output.
   • Inspect the array contents and adjust as needed.

Tips for Working with $plugin_meta

1. Backup Before Editing:
   
   • Always create a backup of your plugin files before making changes.
2. Use Debugging Tools:
   
   • Tools like Query Monitor can help inspect plugin metadata without manual print statements.
3. Limit Output to Admins:

Ensure the output is visible only to administrators by wrapping the function in an admin check:
if (current_user_can(‘administrator’)) {

    add_filter(‘plugin_row_meta’, ‘print_plugin_meta’, 10, 3);

}

Troubleshooting Common Issues

1. Output Not Showing:
   
   • Verify that the plugin_row_meta hook is active for your plugin.
2. Array Structure Unclear:
   
   • Use tools like var_dump or wp_debug_log for additional clarity.
3. Errors in WordPress Admin Panel:
   
   • Check for syntax errors in your PHP code.
