Support » Plugin: CM Download Manager » Download button has no effect

    This post is both a problem and solution, but I thought it might help some people.

    I was able to upload files effectively, but downloads were a problem.

    • Screen shots just displayed the last shot and wouldn’t scroll.
    • The description was completely missing
    • The Download button had no effect when clicked

    I checked the browser developer console, and Firefox threw an error when trying to load script http://cdn.jquerytools.org/1.2.7/full/jquery.tools.min.js.

    My site is strictly SSL (https), and Firefox would not allow inclusion of a file via http. This is considered a security risk, as it constitutes “mixed content”, as described here. Chrome wouldn’t allow this either. I didn’t test it with IE, but later versions of that probably wouldn’t like it either.

    The jquerytools.org site doesn’t support https, so the only solution I could think of was to transfer the script to my own site and access that via the prevailing protocol. Thus, here’s what I did to fix this:

    • Download jquery.tools.min.js from jquerytools.org
    • Upload jquerytools.org to my own site
    • Open wp-content/plugins/cm-download-manager/lib/controllers/CmdownloadController.php for editing.
    • Down around line 398, edit this line in the overrideTemplate($template) function:
      wp_enqueue_script('jquery-tools', 'http://cdn.jquerytools.org/1.2.7/full/jquery.tools.min.js', array('jquery'));
    • Change to something more like:
      wp_enqueue_script('jquery-tools', '//pnznol.net/js/jquery.tools.min.js', array('jquery'));

    Note that I omitted the protocol from the url so it would use the currently prevailing protocol. Downloads began to work correctly after this change. Now I just have to remember to change this each time I update the plugin.

    Since jquerytools.org doesn’t support https, it would be really great if I could configure CM Download Manager to use a configurable link for jquery.tools.min.js. That would allow the issue to be both well documented and easily solved. Alternatively, the plugin could include jquery.tools.min.js along with the product, and we could avoid the whole issue.
