如何在WordPress后台的某个页面里添加上传按钮
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代码例如:
<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代码例如:
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;});}}});
