Force Category

So … i’m trying to add a function that forces the user to use Categories, so I’ve got this:

function force_post_categ_init()
{
wp_enqueue_script('jquery');
}
function force_post_categ()
{
echo "<script type='text/javascript'>\n";
echo "
jQuery('#publish').click(function()
{
var cats = jQuery('[id^=\"taxonomy\"]')
.find('.selectit')
.find('input');
category_selected=false;
for (counter=0; counter<cats.length; counter++)
{
if (cats.get(counter).checked==true)
{
category_selected=true;
break;
}
}
if(category_selected==false)
{
alert('You have not selected any category for the post. Please select post category.');
setTimeout(\"jQuery('#ajax-loading').css('visibility', 'hidden');\", 100);
jQuery('[id^=\"taxonomy\"]').find('.tabs-panel').css('background', '#F96');
setTimeout(\"jQuery('#publish').removeClass('button-primary-disabled');\", 100);
return false;
}
});
";
echo "</script>\n";
}
add_action('admin_init', 'force_post_categ_init');
add_action('edit_form_advanced', 'force_post_categ');

but I need specific categories selected … like a region and a content related category.

Any ideas?

Maybe … i can force it to have at least three categories selected … and an alert will pop up with “Have you selected a region in the category list?”

Hi

It seems that your code force the user to select at least one category for a post. To force the user to use only specific categories the simpler way would be to hide the categories that you don’t want to be used. You can inject some css and make vincible only the categories that you want to be used.
This could be one way but you can try other different methods.

Thanks!
