How to use oembed_default_width filter in WordPress

Let’s dive into the world of WordPress hooks! Today, we’re talking about the oembed_default_width filter. This nifty filter helps you control the maximum width allowed for embedded content. To get started with it, you’ll want to register it using the add_filter function. You can pop this code into your theme’s functions.php file or create a custom WordPress plugin. At WePlugins, we recommend using a custom plugin so your settings remain safe even if your theme updates.

Example 1: Basic Usage

Here’s a simple example of how to use the oembed_default_width filter. This code sets up a function that modifies the maximum width.

    function weplugins_modify_oembed_default_width($maxwidth) { 
        // Modify the $maxwidth variable as needed and return it.
        return $maxwidth; 
    }
    // Add the filter
    add_filter("oembed_default_width", "weplugins_modify_oembed_default_width", 10, 1);
    

Example 2: Conditional Width Adjustment

In this example, we show how you can conditionally modify the width based on certain criteria.

    function weplugins_conditional_oembed_width($maxwidth) { 
        if (is_home()) {
            $maxwidth = 500; // Set a different width for the homepage
        }
        return $maxwidth;
    }
    add_filter("oembed_default_width", "weplugins_conditional_oembed_width", 10, 1);
    

Example 3: Removing the Hook

If you need to remove a previously registered filter, you can do so with remove_filter.

    remove_filter("oembed_default_width", "weplugins_modify_oembed_default_width", 10, 1);
    

Make sure to provide the same callback function name, priority, and number of arguments when removing the hook callback.
