The filter has 2 parameters, also the function name doesn’t match. So your code should look like this: add_filter(‘wp_get_attachment_url’, ‘clrs_get_attachment_url’, 10, 2); function clrs_get_attachment_url($url, $post_id) { // Do what you want to $url return $url; }
There’s a few plugins to fix this, but basically it your database still references the images to be “oldsite.com/wp-content/uploads/” and you need it to be “newsite.com/wp-content/uploads” So you have to change all old references. You could use SQL: UPDATE wp_options SET option_value = replace(option_value, ‘http://www.oldsite.com’, ‘http://www.newsite.com’) WHERE option_name = ‘home’ OR option_name = ‘siteurl’; UPDATE … Read more

So, there are some things which work differently (now). I. What you’ve noticed, when you click the checkbox WordPress sends an Ajax request to ‘wp_ajax_save_attachment_compat()’ with some form data, if your checkbox is checked, this information will be part of the form data. ‘wp_ajax_save_attachment_compat()’ checks for $_REQUEST[‘attachments’] and $_REQUEST[‘attachments’][$id] and will fail if it does … Read more
Your files array needs to mimic the $_FILES global so you need to make a dummy page with some file inputs that prints or dumps the contents of $_FILES to see how it is structured. Make a variable that looks like that with your data and pass that wp_handle_sideload(). EDIT: This answer was correct at … Read more
Ok I’ve figured some things out by now: I was not returning the rendered image into anything In the javascript I have a render function media.view.AttachmentsBrowser = media.view.AttachmentsBrowser.extend({ render: function(){ var that = this; if(this.collection){ if(this.collection.models.length > 0){ this.clearImages(); _.each(this.collection.models, function (item){ //old way: that.renderImage(item); //now: this.$el.find(‘#lastli’).before(that.renderImage(item)); }, this); } } } }); Obviously my … Read more
