Require post title – prevent posts with no title

I have the same problem. It’s odd that there’s no setting or plug-in available to prevent it. Would love to hear of a solution.

If anyone’s still interested, I was able to add this feature.

require-title.js (put in your theme directory)

jQuery(document).ready(function($){
	$('#post').submit(function(event){
		var title = $('#title').val();
		if( title.length == 0 || title.replace(/\s/g,'').length == 0 ){
			event.preventDefault();
			$('div#notice').remove();
			$("<div id='notice' class='error below-h2'><p>A title is required for all updates.</p></div>").insertAfter('h2');
			alert("A title is required for all updates");
			$('#title').focus();
			$('#ajax-loading').hide();
			$('#publish').removeClass('button-primary-disabled');
		}
	});
});

(I’m sure this javascript could be written more elegantly.) Then, add this to your theme’s functions.php:

// Require post title
if ( is_admin() ) { wp_enqueue_script('require-post-title', get_bloginfo('template_directory') . '/require-title.js'); }

this will pop up an alert box and put a red box at the top of the new/edit post form if the title is left blank.

I tried your code, but still can publish un-titled posts.. Any ideas?
Thanks
