    The edit_term_link() function in WordPress is used for displaying or retrieving an edit link for a specific term, such as a category or tag, within the WordPress taxonomy system. This function is especially useful for theme and plugin developers who want to provide a quick way for users to edit taxonomy terms from the front end of the site.

    Function Definition:

    edit_term_link( string $link = '', string $before = '', string $after = '', int|WP_Term|null $term = null, bool $display = true ): string|void
    

    Parameters:

    1. $link (string, optional): The anchor text for the edit link. If left empty, the default text will be 'Edit This'. The default value is an empty string ''.

    2. $before (string, optional): Text to display before the edit link. Useful for adding HTML or text formatting. The default value is an empty string ''.

    3. $after (string, optional): Text to display after the edit link. This parameter also allows for additional HTML or text formatting. The default value is an empty string ''.

    4. $term (int|WP_Term|null, optional): The term ID or term object that you want to provide an edit link for. If this parameter is null, WordPress will use the currently queried object. The default value is null.

    5. $display (bool, optional): Determines whether to echo (display) the link (true) or just return it as a string (false). The default value is true.

    Return Value:

    • The function returns either a string or void.
    • If $display is set to true, the edit link is echoed, and the function returns void.
    • If $display is false, the edit link is returned as a string but not displayed.

    Sample Usage:

    Example 1: Basic Usage

    // Display an edit link for a specific term (e.g., term ID is 10)
    edit_term_link('Edit This Term', '', '', 10);
    

    Example 2: Custom Text and HTML Formatting

    // Custom text and HTML before and after the edit link for term ID 10
    edit_term_link('Edit', '<span class="edit-link">', '</span>', 10);
    

    Example 3: Using With Current Queried Object

    // Automatically use the current queried term and return the link instead of displaying it
    $link = edit_term_link('Edit Current Term', '', '', null, false);
    echo '<div class="custom-class">' . $link . '</div>';
    

    In these examples, the function is used to create links that allow users to edit specific terms directly from the front-end of the website, enhancing the usability and efficiency of site management in WordPress.
