Answers:
一个很小的资源,也许是一个用于创建解决方案的插件。首先是php部分,媒体管理器中包含按钮的javascript。是更有用的答案,但是@One Trick Pony的答案是创建正确的方向和JS解决方案。
查看图片上的结果:
生成的简码(如果大小不是默认大小):
挂钩print_media_templates
是包含按钮(标记)的正确位置。也就是排队脚本,那里有附加控件的解决方案。
class Custom_Gallery_Setting {
/**
* Stores the class instance.
*
* @var Custom_Gallery_Setting
*/
private static $instance = null;
/**
* Returns the instance of this class.
*
* It's a singleton class.

public static function get_instance() {
if ( ! self::$instance )
self::$instance = new self;
return self::$instance;

// Put your hands up...
add_action( 'admin_init', array( Custom_Gallery_Setting::get_instance(), 'init_plugin' ), 20 );
以下来源是javascript,在php中的示例来源上,该文件 custom-gallery-setting.js
/**
* Custom Gallery Setting
*/
( function( $ ) {
var media = wp.media;
// Wrap the render() function to append controls
media.view.Settings.Gallery = media.view.Settings.Gallery.extend({
render: function() {
media.view.Settings.prototype.render.apply( this, arguments );
// Append the custom template
this.$el.append( media.template( 'custom-gallery-setting' ) );
// Save the setting
media.gallery.defaults.size = 'thumbnail';
this.update.apply( this, ['size'] );
return this;
}
} );
} )( jQuery );
[gallery type="thumbnail" ids="1,2"]
成为[gallery ids="1,2"]
?我为插件添加了自定义属性,可以选择将图库转换成幻灯片。我只想显示一个普通的WP Gallery,便想隐藏该属性。因此,在停用插件时,它会减少工作量。
如果您确实要使用Backbone模板,那么您的选择是正确的。
我将使用jQuery插入HTML模板,而不是覆盖template()
库设置视图的功能。但是我想您已经知道这一点,因此我将发布Backbone版本:
add_action('print_media_templates', function(){
// define your backbone template;
// the "tmpl-" prefix is required,
// and your input field should have a data-setting attribute
// matching the shortcode name
?>
<script type="text/html" id="tmpl-my-custom-gallery-setting">
<label class="setting">
<span><?php _e('My setting'); ?></span>
<select data-setting="my_custom_attr">
<option value="foo"> Foo </option>
<option value="bar"> Bar </option>
<option value="default_val"> Default Value </option>
</select>
</label>
</script>
<script>
jQuery(document).ready(function(){
// add your shortcode attribute and its default value to the
// gallery settings list; $.extend should work as well...
_.extend(wp.media.gallery.defaults, {
my_custom_attr: 'default_val'
});
// merge default gallery settings template with yours
wp.media.view.Settings.Gallery = wp.media.view.Settings.Gallery.extend({
template: function(view){
return wp.media.template('gallery-settings')(view)
+ wp.media.template('my-custom-gallery-setting')(view);
}
});
});
</script>
<?php
});
