WP Media Gallery Metabox无法读取未定义的属性”状态”

我有一个任务来创建帖子类型的媒体库图像, 例如” woocommerce产品库图像” , 而无需任何插件, 这都是通过meta框自定义的。我创建了元框” Gallery Images” , 也有JS, 但是当我单击” 添加图像” 按钮时, 它没有打开图库以选择图像, 而是在控制台中返回错误

未捕获的TypeError：无法读取未定义的属性” 状态”

【WP Media Gallery Metabox无法读取未定义的属性” 状态” 】我从这里源代码中找到了这段代码
以下是一些屏幕截图：

在第二张照片中, 我做了控制台：

console.log(wp); console.log(wp.media); console.log(wp.media.gallery); console.log(wp.media.gallery.edit(‘ [Gallery ids =” ‘ + val +'” ]’ )+” -框架” );

现在, 这是我的代码：

/* * Add a meta box */ function post_gallery_images_metabox() { add_meta_box( 'post_gallery_images', 'Gallery Images', 'post_gallery_images_metabox_callback', 'inject_template', 'side', 'default' ); } add_action( 'add_meta_boxes', 'post_gallery_images_metabox' ); /* * Meta Box Callback function */ function post_gallery_images_metabox_callback( $post ) {wp_nonce_field( 'save_feat_gallery', 'inject_feat_gallery_nonce' ); $meta_key = 'template_gallery_images'; echo inject_image_uploader_field( $meta_key, get_post_meta($post-> ID, $meta_key, true) ); }function inject_image_uploader_field( $name, $valuehttp://www.srcmini.com/= '' ) {$image = 'Upload Image'; $button = 'button'; $image_size = 'full'; $display = 'none'; ?> < p> < ?php _e( '< i> Choose Images< /i> ', 'mytheme' ); ?> < /p> < label> < div class="gallery-screenshot clearfix"> < ?php { $ids = explode(', ', $value); foreach ($ids as $attachment_id) { $img = wp_get_attachment_image_src($attachment_id, 'thumbnail'); echo '< div class="screen-thumb"> < img src="' . esc_url($img[0]) . '" /> < /div> '; } } ?> < /div> < input id="edit-gallery" class="button upload_gallery_button" type="button" value="http://www.srcmini.com/< ?php esc_html_e('Add/Edit Gallery', 'mytheme') ?> "/> < input id="clear-gallery" class="button upload_gallery_button" type="button" value="http://www.srcmini.com/< ?php esc_html_e('Clear', 'mytheme') ?> "/> < input type="hidden" name="< ?php echo esc_attr($name); ?> " id="< ?php echo esc_attr($name); ?> " class="gallery_values" value="http://www.srcmini.com/< ?php echo esc_attr($value); ?>"> < /label> < ?php }/* * Save Meta Box data */ function template_img_gallery_save( $post_id ) { if ( !isset( $_POST['inject_feat_gallery_nonce'] ) ) { return $post_id; }if ( !wp_verify_nonce( $_POST['inject_feat_gallery_nonce'], 'save_feat_gallery') ) { return $post_id; } if ( isset( $_POST[ 'template_gallery_images' ] ) ) { update_post_meta( $post_id, 'template_gallery_images', esc_attr($_POST['template_gallery_images']) ); } else { update_post_meta( $post_id, 'template_gallery_images', '' ); } } add_action('save_post', 'template_img_gallery_save');

JS：

jQuery(document).ready(function(jQuery) { jQuery('.upload_gallery_button').click(function(event){ var current_gallery = jQuery( this ).closest( 'label' ); console.log(current_gallery); if ( event.currentTarget.id === 'clear-gallery' ) { //remove value from input current_gallery.find( '.gallery_values' ).val( '' ).trigger( 'change' ); //remove preview images current_gallery.find( '.gallery-screenshot' ).html( '' ); return; }// Make sure the media gallery API exists if ( typeof wp === 'undefined' || !wp.media || !wp.media.gallery ) { return; } event.preventDefault(); // Activate the media editor var val = current_gallery.find( '.gallery_values' ).val(); var final; if ( !val ) { final = '[ gallery ids="0" ]'; } else { final = '[ gallery ids="' + val + '" ]'; } var frame = wp.media.gallery.edit( final ); console.log(wp); console.log(wp.media); console.log(wp.media.gallery); console.log(frame + " -- frame"); frame.state( 'gallery-edit' ).on('update', function( selection ) { console.log('coming'); //clear screenshot div so we can append new selected images current_gallery.find( '.gallery-screenshot' ).html( '' ); var element, preview_html = '', preview_img; var ids = selection.models.map( function( e ) { element = e.toJSON(); preview_img = typeof element.sizes.thumbnail !== 'undefined' ? element.sizes.thumbnail.url : element.url; preview_html = "< div class='screen-thumb'> < img src='" + preview_img + "'/> < /div> "; current_gallery.find( '.gallery-screenshot' ).append( preview_html ); return e.id; } ); current_gallery.find( '.gallery_values' ).val( ids.join( ', ' ) ).trigger( 'change' ); } ); return false; }); });

我不知道该怎么办, 为什么会发生此错误。请帮我。
