To use pre_set_theme_mod_name filter, first, you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.
We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.
In the below live example, we have defined a function weplugins_modify_pre_set_theme_mod_name_defaults which takes 2 parameters and we registered using add_filter. The first parameter pre_set_theme_mod_name is the name of the hook. The second parameter weplugins_modify_pre_set_theme_mod_name_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.
Sometimes, you have to remove a registered hook so you can use remove_filter to remove pre_set_theme_mod_name filter.
Below are the 2 parameters required to use this hook.
Below is an example of how you can use this hook.
function weplugins_modify_pre_set_theme_mod_name_defaults($value, $old_value) {
// Update the $value variable according to your website requirements and return this variable. You can modify the $value variable conditionally too if you want.
return $value;
}
// add the filter
add_filter("pre_set_theme_mod_name", "weplugins_modify_pre_set_theme_mod_name_defaults", 10, 2);
This example demonstrates how to use the hook to modify a specific theme mod.
function weplugins_modify_header_textcolor($value, $old_value) {
if ($old_value == '000000') {
$value = 'ffffff';
}
return $value;
}
// add the filter
add_filter("pre_set_theme_mod_header_textcolor", "weplugins_modify_header_textcolor", 10, 2);
To remove a hook callback, use the example below.
remove_filter("pre_set_theme_mod_name", "weplugins_modify_pre_set_theme_mod_name_defaults", 10, 2);
Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.
