Hier ist das Skript:
Ich benutze die Funktion loadImages
im folgenden Skript, um die vorhandenen angehängten Bilder über AJAX zu laden, und übergebe dann einfach die Funktion mit den IDs der Bilder und es wird ein vorab ausgefülltes Modal geöffnet.
var frame,
selection = loadImages(images);
$('#stag_images_upload').on('click', function(e) {
e.preventDefault();
var options = {
title: '<?php _e("Create Featured Gallery", "stag"); ?>',
state: 'gallery-edit',
frame: 'post',
selection: selection
};
frame = wp.media(options).open();
frame.menu.get('view').unset('cancel');
frame.menu.get('view').unset('separateCancel');
frame.menu.get('view').get('gallery-edit').el.innerHTML = '<?php _e("Edit Featured Gallery", "stag"); ?>';
frame.content.get('view').sidebar.unset('gallery'); // Hide Gallery Settings in sidebar
// when editing a gallery
overrideGalleryInsert();
frame.on( 'toolbar:render:gallery-edit', function() {
overrideGalleryInsert();
});
frame.on( 'content:render:browse', function( browser ) {
if ( !browser ) return;
// Hide Gallery Settings in sidebar
browser.sidebar.on('ready', function(){
browser.sidebar.unset('gallery');
});
// Hide filter/search as they don't work
browser.toolbar.on('ready', function(){
if(browser.toolbar.controller._state == 'gallery-library'){
browser.toolbar.$el.hide();
}
});
});
// All images removed
frame.state().get('library').on( 'remove', function() {
var models = frame.state().get('library');
if(models.length == 0){
selection = false;
$.post(ajaxurl, { ids: '', action: 'stag_save_images', post_id: stag_ajax.post_id, nonce: stag_ajax.nonce });
}
});
function overrideGalleryInsert(){
frame.toolbar.get('view').set({
insert: {
style: 'primary',
text: '<?php _e("Save Featured Gallery", "stag"); ?>',
click: function(){
var models = frame.state().get('library'),
ids = '';
models.each( function( attachment ) {
ids += attachment.id + ','
});
this.el.innerHTML = '<?php _e("Saving...", "stag"); ?>';
$.ajax({
type: 'POST',
url: ajaxurl,
data: {
ids: ids,
action: 'stag_save_images',
post_id: stag_ajax.post_id,
nonce: stag_ajax.nonce
},
success: function(){
selection = loadImages(ids);
$('#_stag_image_ids').val( ids );
frame.close();
},
dataType: 'html'
}).done( function( data ) {
$('.stag-gallery-thumbs').html( data );
console.log(data);
});
}
}
});
}
function loadImages(images){
if (images){
var shortcode = new wp.shortcode({
tag: 'gallery',
attrs: { ids: images },
type: 'single'
});
var attachments = wp.media.gallery.attachments( shortcode );
var selection = new wp.media.model.Selection( attachments.models, {
props: attachments.props.toJSON(),
multiple: true
});
selection.gallery = attachments.gallery;
selection.more().done( function() {
// Break ties with the query.
selection.props.set({ query: false });
selection.unmirror();
selection.props.unset('orderby');
});
return selection;
}
return false;
}
});
Und hier ist die PHP-Funktion, die die AJAX-Anfrage bearbeitet:
function stag_save_images(){
if( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE ){
return;
}
if ( !isset($_POST['ids']) || !isset($_POST['nonce']) || !wp_verify_nonce( $_POST['nonce'], 'stag-ajax' ) ){
return;
}
if ( !current_user_can( 'edit_posts' ) ) return;
$ids = strip_tags(rtrim($_POST['ids'], ','));
update_post_meta($_POST['post_id'], '_stag_image_ids', $ids);
$thumbs = explode(',', $ids);
$thumbs_output = '';
foreach( $thumbs as $thumb ) {
$thumbs_output .= '<li>' . wp_get_attachment_image( $thumb, array(75,75) ) . '</li>';
}
echo $thumbs_output;
die();
}
add_action( 'wp_ajax_stag_save_images', 'stag_save_images' );
function stag_metabox_scripts(){
global $post;
if( isset($post) ) {
wp_localize_script( 'jquery', 'stag_ajax', array(
'post_id' => $post->ID,
'nonce' => wp_create_nonce( 'stag-ajax' )
) );
}
}
add_action( 'admin_enqueue_scripts', 'stag_metabox_scripts' );
Ich habe gerade das Snippet aus meinem WordPress-Framework kopiert, ich hoffe, es macht Sinn.
