我是jQuery的初学者,使用WordPress Media Uploader的多图像上传按钮工具无法正常工作,我需要知道如何正确执行操作。

这是我的代码:Javascript / jQuery用于显示媒体上传器并处理所选图像:

jQuery(document).ready( function($){

var mediaUploader;

$('#upload-button').on('click',function(e) {
    e.preventDefault();
    if( mediaUploader ){
        mediaUploader.open();
        return;
    }

  mediaUploader = wp.media.frames.file_frame =wp.media({
    title: 'Choose a Hotel Picture',
    button: {
        text: 'Choose Picture'
    },
    multiple:false
  });

  mediaUploader.on('select', function(){
    attachment = mediaUploader.state().get('selection').first().toJSON();
    $('#profile-picture').val(attachment.url);
    $('#profile-picture-preview').css('background-image','url(' + attachment.url + ')');
  });
  mediaUploader.open();
}); });




<input type="button" id="upload-button1" class="button button-secondary" value="Upload Profiel Picture">
<input type="hidden" name="profile_picture1" id="profile-picture1" value="'.$picture.'">

<input type="button" id="upload-button2" class="button button-secondary" value="Upload Profiel Picture">
<input type="hidden" name="profile_picture2" id="profile-picture2" value="'.$picture.'">

非常感谢您一如既往的帮助。

您只需将选择器的ID从“ ID”更改为“ Classs”,即可使媒体上传器在不同的按钮上使用。

然后,您需要创建一个标识符,以便使用正确的输入字段来设置图像。就我而言,我使用了数据属性。

jQuery(document).ready( function($){

var mediaUploader;

$('.upload-button').on('click',function(e) {
    e.preventDefault();
    var buttonID = $(this).data('group');

    if( mediaUploader ){
        mediaUploader.open();
        return;
    }

  mediaUploader = wp.media.frames.file_frame =wp.media({
    title: 'Choose a Hotel Picture',
    button: {
        text: 'Choose Picture'
    },
    multiple:false
  });

  mediaUploader.on('select', function(){
    attachment = mediaUploader.state().get('selection').first().toJSON();
    $('#profile-picture'+buttonID).val(attachment.url);
    $('#profile-picture-preview'+buttonID).css('background-image','url(' + attachment.url + ')');
  });
  mediaUploader.open();
}); });




<input type="button" class="button button-secondary upload-button" value="Upload Profile Picture" data-group="1">
<input type="hidden" name="profile_picture1" id="profile-picture1" value="'.$picture1.'">

<input type="button" class="button button-secondary upload-button" value="Upload Profile Picture" data-group="2">
<input type="hidden" name="profile_picture2" id="profile-picture2" value="'.$picture2.'">
