Prevent posting when no category is selected

    Hello,

    I’m trying to trigger an action if, when a user tries to publish a post, no category is selected:
    – It could either be just an alert message (and the post is still published);
    – Or actually alter message + preventing the post from being published.

    Searching on this forum, I’ve found the code:

    jQuery('#submitdiv').on('click','#publish',function(e){
            var $checked = jQuery('#category-all li input:checked');
            if ( $checked.length <= 0 ) { //Checks if cat is selected
            alert("Please Select atleast one category");
            return false;
            }else{ //Else continue
                return true;
            }
            });

    But I have no idea where to put it.

    Thanks!

    I have tried using the publish_post hook, but apparently there is an error on line:
    jQuery('#submitdiv').on('click','#publish',function(e){

    Hey do you have a link to the forum post where you found it?

    I can have a look tomorrow for you (its late night here in NZ!)

    I double checked and it wasn’t in these forums, it was there:

    Thanks for your help!

    Hey

    OK I tested the JS you posted, it was fine.

    So I guess the issue must be somewhere else. What error did you get from line jQuery('#submitdiv').on('click','#publish',function(e){?

    Anyway, as I don’t know how (or where) you’re calling the JS, I have written you a very basic plugin to do what you need. You can download it at: https://github.com/Shortwave-Web-Solutions-Ltd/force-js-on-wp-admin-post-page

    Just edit the force-js-on-wp-admin-post-page.js file, save your JS code in there then it will throw up your alert on both the add post and edit post screens (just incase someone removes all existing categories or edits a post that doesn’t have categories after you’ve implemented the plugin).

    That should solve your problem, let me know if you have any more issues with it.

    Cheers
    Chris

    Thanks for the script. I’ve added it to my functions.php file used in the child theme.
    There’s no error now, but nothing happens, no javascript reaction at all… (publishing a new page or editing an old one)

    Did you try the Plugin? Did that work?

    The plugin does work, yes, thanks!

    I was just wondering how to include it in functions.php instead of using a plugin?

    Ah that’s good just wanted to make sure there was nothing weird happening with the Javascript.

    OK so can you try replacing the jquery code with just a simple alert box that pops up on page load?

    Sorry meant to say, use the alert box in your theme we can do away with the Plugin now we know the js does work on your page

    I just managed to add the code to functions.php of the child theme. It does work, and no plugin required. Thanks for helping mate!

    add_action( 'admin_enqueue_scripts', 'my_enqueue' );

function my_enqueue($hook) {
	$pages = array('post.php','post-new.php');
	if (in_array($hook, $pages)) {
		wp_enqueue_script( 'my_custom_script', get_stylesheet_directory_uri() . '/force-js-on-wp-admin-post-page.js',array(),FALSE,TRUE);
	} else {
		return;
	}
}

    I do have another problem though: the script is applied even for non-articles posts like the portfolio or some plugins using the post.php file.
    How can I restrict it only for the publication of articles?
    Thanks!

    How do you define ‘non-articles’? Are they setup as custom post types, in a particular category or have particular tags?

    Yes, custom post types, including the wordpress portfolio.
    I was wondering how I could restrict the script to be applied only to articles belonging to certain categories.

    (by categories, I mean, not custom post types, for example)

    Without seeing your code, my guess would be having a play with the $pages array…
