小部件中的WordPress媒体上传器 _WordPress开发

我已经在WordPress主题中创建了一个小部件以显示图像。到目前为止, 该小部件的工作原理是, 我可以输入值并将其显示在前端。
当我选择一个小部件并将其放入小部件区域时, 媒体上载按钮不起作用。在WordPress屏幕的左窗格中, 你可以选择要使用的小部件。当我取消隐藏(在display：none设置)时, 这些小部件的代码然后在此处使用上载按钮, 则可以正常工作。我猜是因为它在放入小部件区域之前被调用。
我知道WordPress为每个小部件添加了唯一的参数, 因此它们不会相互冲突。因此, 我认为我需要为.js文件传递唯一的参数：＃cc-image-upload-file和＃cc-image-upload-file-button。但是我不知道该怎么做。
【小部件中的WordPress媒体上传器】那么谁能帮助我解决这个问题呢？

media-upload.js

jQuery(document).ready(function($){var custom_uploader; $('#cc-image-upload-file-button').click(function(e) {e.preventDefault(); //If the uploader object has already been created, reopen the dialog if (custom_uploader) { custom_uploader.open(); return; }//Extend the wp.media object custom_uploader = wp.media.frames.file_frame = wp.media({ title: 'Choose File', button: { text: 'Choose File' }, multiple: false }); //When a file is selected, grab the URL and set it as the text field's value custom_uploader.live('select', function() { attachment = custom_uploader.state().get('selection').first().toJSON(); $('#cc-image-upload-file').val(attachment.url); }); //Open the uploader dialog custom_uploader.open(); }); });

#1Thnx Obmerk的答复。我发现了另一个使用不同脚本的解决方案, 它可行:)

jQuery(document).ready( function(){ function media_upload( button_class) { var _custom_media = true, _orig_send_attachment = wp.media.editor.send.attachment; jQuery('body').on('click', button_class, function(e) { var button_id ='#'+jQuery(this).attr('id'); /* console.log(button_id); */ var self = jQuery(button_id); var send_attachment_bkp = wp.media.editor.send.attachment; var button = jQuery(button_id); var id = button.attr('id').replace('_button', ''); _custom_media = true; wp.media.editor.send.attachment = function(props, attachment){ if ( _custom_media) { jQuery('.custom_media_id').val(attachment.id); jQuery('.custom_media_url').val(attachment.url); jQuery('.custom_media_image').attr('src', attachment.url).css('display', 'block'); } else { return _orig_send_attachment.apply( button_id, [props, attachment] ); } } wp.media.editor.open(button); return false; }); } media_upload( '.custom_media_upload'); });

jQuery(document).ready(function ($) {var custom_uploader; $('#cc-image-upload-file-button').click(function (e) {e.preventDefault(); //Extend the wp.media object custom_uploader = wp.media.frames.file_frame = wp.media({ title: 'Seleccione o adjunte archivo csv de importación', button: { text: 'Seleccione csv' }, multiple: false }); //When a file is selected, grab the URL and set it as the text field's value custom_uploader.on('select', function () { attachment = custom_uploader.state().get('selection').first().toJSON(); $('#cc-image-upload-file').val(attachment.url); }); //If the uploader object has already been created, reopen the dialog if (custom_uploader) { custom_uploader.open(); return; }//Open the uploader dialog custom_uploader.open(); }); });

#3我在博客中使用Uploadcare.com小部件。嵌入极其简单, 外观漂亮, 而??且他们有免费的计划, 对我来说足够了。这是插件http://wordpress.org/plugins/uploadcare/
