How to use emoji_svg_ext filter in WordPress

emoji_svg_ext filter

Filters the extension of the emoji SVG files.

To use the emoji_svg_ext filter, first you have to register it using add_filter. You can write this code into the 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 modify_emoji_svg_ext_defaults which takes 1 parameter and we registered it using add_filter. The first parameter emoji_svg_ext is the name of the hook, the second parameter modify_emoji_svg_ext_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.

Sometime, you have to remove a registered hook so you can use remove_filter to remove emoji_svg_ext filter.

Parameters

Below the 1 parameter is required to use this hook.

• $extension: (string) The emoji extension for svg files. Default .svg.

Live Examples

Example 1: Modify the Extension

Below is an example of how you can use this hook to modify the emoji SVG extension.

    function weplugins_modify_emoji_svg_ext_defaults($extension) { 
        // Update the $extension variable according to your website requirements and return this variable. 
        return '.customsvg'; 
    }
    // Add the filter
    add_filter("emoji_svg_ext", "weplugins_modify_emoji_svg_ext_defaults", 10, 1);
    

Example 2: Conditional Modification

In this example, we modify the emoji extension conditionally based on some criteria.

    function weplugins_conditional_emoji_svg_ext($extension) { 
        if (some_condition()) {
            return '.conditionalsvg'; 
        }
        return $extension; 
    }
    // Add the filter
    add_filter("emoji_svg_ext", "weplugins_conditional_emoji_svg_ext", 10, 1);
    

Example 3: Removing the Hook

To remove a hook callback, use the example below. Make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

    // Remove the filter
    remove_filter("emoji_svg_ext", "weplugins_modify_emoji_svg_ext_defaults", 10, 1);
