List More Custom Field Names vs Simply Show Hooks

By default, WordPress only allows 30 custom field names/keys to be listed in the dropdown selection ‘Name’ field when writing a post or page. If you, or the plugins you use, make use of a lot of custom field key names, you may surpass the default limit resulting in some custom field keys not being listed. This may force post authors to manually type in custom field key names if they aren’t listed, which increases the chances for naming errors (typos, or not using the precise key name that is needed). This may also cause some authors concern wondering where previously used custom field keys have gone since they aren’t listed. This plugin increases the limit to 200 custom field key names. There is no settings page to customize the default value. If you’d like to list some number of custom field key names other than 200 (say, for example, 100), you can do so in either of two ways: By editing your wp-config.php file and at the end adding a line such as: define( ‘CUSTOM_FIELD_NAMES_LIMIT’, 100 ); -or- Somewhere — ideally in a mu-plugin or site-specific plugin, or less ideally your active theme’s functions.php file — hook the ‘c2c_list_more_custom_field_names’ filter and return the number you’d like to use: add_filter( ‘c2c_list_more_custom_field_names’, function ( $limit ) { return 100; } ); Notes: * The constant, if defined and truthy, takes precedence over the filter. * If either the constant is defined or the filter is hooked but the value configured or returned is not an integer (or an integer string), then the plugin’s default will be used. * The limit specified must be equal to or greater than the WordPress default of 30.

Up until now the way theme and plugin developers find where to hook into with their add_action() and add_filter() functions is either to search through the WordPress code base, or find find a reference to the hook in the codex. What Simply Show Hooks does is give you a simpler way to see these hooks by displaying them in-line on the page that you are on. All that’s left to do then is copy the hook you need, and paste it in to your add_action and add_filter functions like this: add_action( ‘wp_enqueue_scripts’, ‘my_enqueue_scripts_action’ ); add_filter( ‘the_title’, ‘my_the_title_filter’ ); I made this plugin so I could find WordPress hooks quicker and I use it all the time, so I thought I’d share it and see if it could help others. Enjoy! Please note that in odd cases, due to the nature of actions and filters, the plugin may display a hook in place that disrupts the display of your site – in which case we always display the ‘Hide Hooks’ button so you can switch it back off. This won’t disrupt the look of you site to anyone but you so don’t worry.
