migration - How can I dynamically set the base URL of an ACF custom URL field?

admin管理员组

文章数量:1125913

I have created a custom ACF field called Slide URL in the admin post editor. Am I able to use a system/global variable in here to resolve the base URL for the environment that wordpress is installed on? For example, it would be great to use something like: [var:BaseURL]/my-page.

This means that when I move from the staging environment to the production environment I won't need to change the base URL to the new production environment for every post.

Grateful for your help.

Add the following code to dynamically set the base URL for your ACF custom URL field.

Replace slide_url with the name of your ACF custom URL field

function custom_acf_slide_url_base_url($value, $post_id, $field) {
    // Get the base URL dynamically based on the environment
    $base_url = '';
    if (strpos(site_url(), 'staging') !== false) {
        $base_url = 'https://staging.example.com'; // Replace with your staging URL
    } else {
        $base_url = 'https://www.example.com'; // Replace with your production URL
    }

    // Append the relative path to the base URL
    $slide_url = $base_url . '/my-page';

    return $slide_url;
}

add_filter('acf/load_value/name=slide_url', 'custom_acf_slide_url_base_url', 10, 3);
