How to Change Any Text in WordPress Using Filters

WordPress provides powerful hooks that allow you to modify text dynamically. Whether you’re running an eCommerce store with WooCommerce or just need to tweak some wording across your site, you can use filters like gettext and woocommerce_attribute_label to change text easily.

Using the `gettext` Filter

The gettext filter is one of the most common ways to change text in WordPress. It intercepts translated strings before they are displayed on the site, allowing you to modify them.


add_filter('gettext', function ($translated_text, $text, $domain) {
    if ($text === 'Brand') { // Change 'Brand' to the current label in your store
        return 'Designed by';
    }
    return $translated_text;
}, 10, 3);

In this example, any instance of the word “Brand” will be replaced with “Designed by.” This is particularly useful for WooCommerce or themes that use predefined text.

Modifying WooCommerce Attribute Labels

If you want to change product attribute labels (like “Brand” to “Manufacturer”), you can use the woocommerce_attribute_label filter.


add_filter('woocommerce_attribute_label', function ($label, $name) {
    if ($name === 'pa_brand') { // Adjust the attribute slug accordingly
        return 'Manufacturer'; // Change to your preferred label
    }
    return $label;
}, 10, 2);

This method ensures that the label appears as expected in product pages, filters, and attribute lists.

When to Use These Filters

Use gettext when changing general text across the site.
Use woocommerce_attribute_label when modifying product attribute names.
For complex text replacements, consider using a translation plugin like Loco Translate.

Final Thoughts

With WordPress filters, you can easily modify any text to better suit your branding. These small tweaks help improve user experience and maintain consistency throughout your site.
