Add Snippet To Project
Are you trying to add more options to your custom fields dropdown in WordPress but find yourself limited by the default settings? The good news is that WordPress allows you to increase the default number of fields in your custom fields dropdown. This can be a real game-changer especially for those who run complex websites with a need for additional custom fields. In this tutorial, we’ll guide you through the simple steps to customize and increase the default number of fields in your custom fields dropdown. Let’s dive in.
function wpturbo_increase_custom_fields_dropdown($limit) {
return 100; // Increase to your desired number
}
add_filter('postmeta_form_limit', 'wpturbo_increase_custom_fields_dropdown');
The code snippet provided helps to increase the number of fields that show up in the custom fields dropdown menu in the WordPress editor. It does this by defining a function called wpturbo_increase_custom_fields_dropdown() and then hooking this function into the WordPress filter postmeta_form_limit.
Let’s break this down step by step:
function wpturbo_increase_custom_fields_dropdown($limit) {
return 100; // Increase to your desired number
}The wpturbo_increase_custom_fields_dropdown() function is a user-defined function that takes in a parameter $limit. This $limit represents the initial limit of the custom fields drop-down menu. In the WordPress core, this limit is set to a specific number, but it can be overridden by using the above function.
Within this function, there’s a return statement that simply returns the number 100. This is the new limit for the custom fields drop down. So, instead of the default number of input fields that WordPress provides, it specifies that we want to see a maximum of 100 fields. You can replace 100 with any number you desire, depending on your specific needs and the performance impact you’re willing to accept.
The final part of the code snippet is the add_filter() WordPress function. This function is used to hook the wpturbo_increase_custom_fields_dropdown() function into the postmeta_form_limit filter:
add_filter('postmeta_form_limit', 'wpturbo_increase_custom_fields_dropdown');The ‘postmeta_form_limit’ filter is located where WordPress generates the custom fields drop-down menu. By connecting (‘hooking’) our function to this filter, we instruct WordPress to pass the limit value through our function before making the dropdown. This enables us to increase the limit value and subsequently the number of fields displayed in the drop-down.
In summary, the entire script is used to increase the number of custom fields displayed in the WordPress editor by overriding the default setting with a user-defined limit.
