[英]wp.media undefined using Wordpress Media Uploader
Edit: Other variations of scripts don't seem to work either, the wp_enqueue_media() goes alright, but it looks like the script that includes the wp.media is not included.编辑:脚本的其他变体似乎也不起作用, wp_enqueue_media() 没问题,但看起来包含 wp.media 的脚本不包括在内。
I'm trying to use the Wordpress Media Uploader in a custom plugin, but keep getting the following error:我正在尝试在自定义插件中使用 Wordpress Media Uploader,但不断收到以下错误:
TypeError: undefined is not an object (evaluating 'wp.media.frames')
My Javascript-code:我的 Javascript 代码:
jQuery(document).ready(function(){
var mediaUploader;
jQuery('#upload-button').click(function(e) {
e.preventDefault();
// If the uploader object has already been created, reopen the dialog
if (mediaUploader) {
mediaUploader.open();
return;
}
// Extend the wp.media object
mediaUploader = wp.media.frames.file_frame = wp.media({
title: 'Choose Image',
button: {
text: 'Choose Image'
}, multiple: false });
// When a file is selected, grab the URL and set it as the text field's value
mediaUploader.on('select', function() {
var attachment = mediaUploader.state().get('selection').first().toJSON();
jQuery('#logo').val(attachment.url);
});
// Open the uploader dialog
mediaUploader.open();
});
});
The .js files are registered as follows: .js 文件注册如下:
/* Add the media uploader script */
function my_media_lib_uploader_enqueue() {
wp_enqueue_media();
wp_register_script( 'media-lib-uploader-js', plugins_url( 'media-lib-uploader.js' , __FILE__ ), array('jquery') );
wp_enqueue_script( 'media-lib-uploader-js' );
}
add_action('admin_enqueue_scripts', 'my_media_lib_uploader_enqueue');
Solved the problem, the problem was that wp_enqueue_media();问题解决了,问题出在 wp_enqueue_media(); calls the scripts into the footer of the page.
将脚本调用到页面的页脚中。 Because I was using a die() function somewhere, the scripts weren't loaded.
因为我在某处使用了 die() 函数,所以没有加载脚本。
put the wp_enqueue_media
function in your enqueue scripts function.将
wp_enqueue_media
函数放在您的入队脚本函数中。
Example:例子:
add_action('wp_enqueue_scripts', 'prince_load_scripts');
function prince_load_scripts(){
wp_enqueue_media();
//Yor scripts goes here...
}
I also had a similiar problem... The scripts didn't load on one specific page, especially the scripts wp-media, which lead to the error "wp.media is not defined"... all the solutions didn't work.我也有一个类似的问题......脚本没有加载到一个特定的页面上,尤其是脚本 wp-media,导致错误“wp.media 未定义”......所有解决方案都不起作用. It turned out the content on this page was too massive, my PHP Memory Limit was to low.
原来这个页面的内容太大了,我的PHP内存限制太低了。 Setting up MemoryLimit 256->512 worked for me...
设置 MemoryLimit 256->512 对我有用...
