Error in functions.php – Method add_ajax_library

Hello,

your code

function add_ajax_library() {

    $html = '<script type="text/javascript">';
        $html .= 'var ajaxurl = "' . admin_url( 'admin-ajax.php' ) . '"';
    $html .= '</script>';

    echo $html;
}

is missing a ; at the end. Correct code:

function add_ajax_library() {

    $html = '<script type="text/javascript">';
        $html .= 'var ajaxurl = "' . admin_url( 'admin-ajax.php' ) . '";';
    $html .= '</script>';

    echo $html;
}
