    The get_link_to_edit function in WordPress is used to retrieve link data based on its ID, which can be useful when editing links in custom development scenarios. Here's a detailed explanation and sample usage:

    Function Definition:

    get_link_to_edit( int|stdClass $link ): object
    

    Function Purpose:

    • Retrieves link data for editing: This function is specifically designed to fetch the details of a link from the WordPress database. It's primarily used in scenarios where you need to edit or display the link's information in the WordPress backend or in custom development tasks.

    Parameters:

    • $link (int | stdClass): This is a required parameter.
      • Int: If you pass an integer, it is assumed to be the ID of the link you want to retrieve.
      • stdClass: Alternatively, you can pass a link object if you already have one, and the function will return the corresponding link object for editing.

    Return:

    • Object: The function returns a link object that contains all the relevant data for the link. This object can be used to access and modify various properties of the link, such as its URL, name, description, and more.

    Sample Usage:

    // Assume you have a link ID
    $link_id = 123; // Replace with your actual link ID
    
    // Retrieve the link object
    $link_object = get_link_to_edit($link_id);
    
    // Check if the link object is retrieved successfully
    if ( ! is_null($link_object) ) {
        // Access link properties
        $link_url = $link_object->link_url;
        $link_name = $link_object->link_name;
        // ... other properties
    
        // Code to edit or display the link details
        // For example, displaying the link name and URL
        echo 'Link Name: ' . esc_html($link_name);
        echo 'Link URL: ' . esc_url($link_url);
        // ... further code for editing or processing
    } else {
        echo 'Link not found.';
    }
    

    Notes:

    • Check for Existence: Always check if the link object is retrieved successfully to avoid errors.
    • Escaping Data: When displaying link data, ensure to escape it properly to prevent security issues, such as XSS attacks.
    • WordPress Context: This function is specific to WordPress, so it should be used within a WordPress environment.

    Remember, this function is part of the WordPress core, so it's recommended to refer to the WordPress Codex or Developer Resources for the most updated information and best practices.
