如果你需要在后台某个页面添加上传按钮,你需要用到 wp_enqueue_media()这个函数,用于引入上传所需组件。
- add_action ( 'admin_enqueue_scripts', function () {
- if (is_admin ())
- wp_enqueue_media ();
- } );
html 代码:
- <p>
- <input type="number" value="" class="regular-text process_custom_images" id="process_custom_images" name="" max="" min="1" step="1">
- <button class="set_custom_images button">Set Image ID</button>
- </p>
js 代码:
- jQuery(document).ready(function() {
- var $ = jQuery;
- if ($('.set_custom_images').length > 0) {
- if ( typeof wp !== 'undefined' && wp.media && wp.media.editor) {
- $(document).on('click', '.set_custom_images', function(e) {
- e.preventDefault();
- var button = $(this);
- var id = button.prev();
- wp.media.editor.send.attachment = function(props, attachment) {
- id.val(attachment.url);
- };
- wp.media.editor.open(button);
- return false;
- });
- }
- }
- });
