How to use documentation_ignore_functions filter in WordPress

WordPress hooks are like magic wands for developers, especially for us folks who love tinkering around with code. One such hook is the documentation_ignore_functions filter, which helps you filter out certain functions and classes from the documentation lookup. It’s a handy tool, and I’m excited to share how you can make the most of it.

Example 1: Basic Usage of documentation_ignore_functions

Here’s a simple example to get you started. This snippet modifies the default list of functions to be ignored.

    function weplugins_modify_documentation_ignore_functions_defaults($ignore_functions) { 
        // Update the $ignore_functions variable according to your website requirements and return this variable.
        return $ignore_functions; 
    }
    add_filter("documentation_ignore_functions", "weplugins_modify_documentation_ignore_functions_defaults", 10, 1);
    

Example 2: Conditional Modification

Sometimes, you might want to modify the ignored functions list based on certain conditions. Here’s how you can do that.

    function weplugins_conditional_ignore_functions($ignore_functions) {
        if (is_admin()) {
            // Modify the $ignore_functions array specifically for admin pages.
        }
        return $ignore_functions;
    }
    add_filter("documentation_ignore_functions", "weplugins_conditional_ignore_functions", 10, 1);
    

Example 3: Removing the Hook

If you need to remove a previously registered hook, here’s how you can achieve it.

    remove_filter("documentation_ignore_functions", "weplugins_modify_documentation_ignore_functions_defaults", 10, 1);
