I am trying to trigger an even upon saving / updating a post in wordpress… see here:
add_action('save_post', 'generate_location');
function generate_location($post_id) {
echo "hey";
}
the problem is that its not working…
any ideas why? Syntax?
WordPress implements the Post/Redirect/Get pattern to avoid duplicate form submissions, so you’re not going to see anything
echo‘d from asave_postcallback.Instead, you can do a
wp_die( 'hey' )instead, or log something to the database or file system.I don’t know whether you got this working, but I was having the same issue and discovered how to fix it!
in wp-includes/post.php on line 2940 (at the time of writing), this if/else is run whilst saving a post:
You will notice that, if there is an error with the template the function stops there and save_post is never called.
In my case, the posts I was trying to save were imported from a pre-existing site. The new site had no page templates at all, so WP was still trying to save the page with the template from before, failing, and thus; save_post was never called.
I added
to page.php, bulk edit, selected the template and saved. Remove the template name from page.php (as it shows up twice(, and now save_post is triggered every time.
This was the solution in my case anyway. i’m sure it’ll affect someone else, somewhere down the line.
