Support » Plugin: Range Slider For Contact Form 7 » jQuery(…).slider is not a function

  • ozzy1986


    Great plugin!

    Can’t solve the problem with jquery slider library though.
    I get this:
    Uncaught TypeError: jQuery(…).slider is not a function
    at HTMLDivElement.<anonymous> (front.js?ver=2.0.0:45)
    at Function.each (jquery.min.js?ver=3.6.0:2)
    at s.fn.init.each (jquery.min.js?ver=3.6.0:2)
    at HTMLDocument.<anonymous> (front.js?ver=2.0.0:2)
    at e (jquery.min.js?ver=3.6.0:2)
    at t (jquery.min.js?ver=3.6.0:2)

    I thought that some js libraries haven’t gotten loaded but this is the sequence:

    So you can see that jquery and jquery-ui along with other libraries are loaded properly and in time.

    I just realized that jquery got attached twice. Removing the latter one solved the problem.

    However it’s strange that I had to remove plugin’s attachment of jquery by changing:
    wp_enqueue_script( 'OCCF7RS-front-js', OCCF7RS_PLUGIN_DIR . '/includes/js/front.js', array('jquery'), '2.0.0' );
    wp_enqueue_script( 'OCCF7RS-front-js', OCCF7RS_PLUGIN_DIR . '/includes/js/front.js', array(), '2.0.0' );

    Looks like with this code jquery is loaded AFTER all other plugin’s js scripts. I wonder why and how to solve it without editing plugin’s core.



    Thanks for this topic. I have the same issue. Solved it with adding a check if jquery is alreayd loaded in the plugins code.

    if ( ! wp_script_is( 'jquery', 'enqueued' )) {
            wp_enqueue_script( 'jquery' );
