WordPress version: 3.4.2
WordPress SEO version: 22.214.171.124
I did this:
I've tried a number of different things to try to get the "wpseo_metabox_prio" filter to work...and nothing seems to do the trick...so I dug into the source code of the WPSEO plugin and found that in the file "/plugins/wordpress-seo/admin/class-metabox.php" there were two instances that called the "add_meta_box()" function. The first (on line 144) shows the new 'wpseo_metabox_prio" filter in place....but the second (on line 215) did not have the filter added in the same way. I added the filter on this line (215) to replicate what I saw in the first (144) and suddenly my custom filter (in my functions.php file) appeared to be working:
From my functions.php file:
// Filter Yoast Meta Priority add_filter( 'wpseo_metabox_prio', 'low');
I expected the plugin to do this:
I expected the plugin filter of 'wpseo_metabox_prio" to work "out of the box"...but couldn't get anything to respond without adding the filter to line 215 of class-metabox.php, as described above.
Instead it did this:
The priority of the WordPress SEO plugin metaboxes remained unchanged...regardless of what I tried to do with the 'wpseo_metabox_prio" filter.
I feel that perhaps the filter needs to be added to line 215 of 'class-metabox.php' in the next release of WPSEO. I'm guessing it was just missed when this new filter was added back in version 1.1.7.
