Javascript 自定义窗口小部件中的图像上载
我在wp小部件中上传图像时遇到问题。下面是functions.php中的代码Javascript 自定义窗口小部件中的图像上载,javascript,php,jquery,wordpress,widget,Javascript,Php,Jquery,Wordpress,Widget,我在wp小部件中上传图像时遇到问题。下面是functions.php中的代码 class about_me extends WP_Widget{ public function __construct(){ parent::__construct('about_me', 'About Me', array( 'description' => 'This is all about me' )); } publ
class about_me extends WP_Widget{
public function __construct(){
parent::__construct('about_me', 'About Me', array(
'description' => 'This is all about me'
));
}
public function form($instance){
$title = $instance['title'];
$desc = $instance['desc'];
$photo = $instance['photo'];
?>
<p><label for="<?php echo $this->get_field_id('title'); ?>">Your Name: </label></p>

<textarea class="widefat" rows="16" cols="20" id="<?php echo $this->get_field_id('desc'); ?>" name="<?php echo $this->get_field_name('desc'); ?>"><?php echo $desc ;?></textarea>

public function widget ($args, $instance){
$title = $instance['title'];
$desc = $instance['desc'];
echo $args['before_widget'].$args['before_title'].$title.$args['after_title']."<div class=\"textwidget\">".$desc."</div>".$args['after_widget'];
}
} // class about_me extends WP_Widget END
add_action('widgets_init', function(){
register_widget('about_me');
});
/*
photo upload option in widget
*/
function photo_upload_option($hook) {
if( $hook != 'widgets.php' )
return;
wp_enqueue_script( 'uploadphoto', get_template_directory_uri() . '/js/upload_image.js', array('jquery', 'media-upload', 'thickbox'), '1.0', 'true' );
wp_enqueue_script( 'media-upload');
wp_enqueue_script( 'thickbox');
wp_enqueue_style ( 'thickbox');
}
add_action('admin_enqueue_scripts', 'photo_upload_option');
}))
这在文本字段中为我提供了一个gravatar链接。但我想在这里选择图像链接
我试过了,但没用。Jquery中可能存在问题。当我从函数中删除“html”变量时,在$('img',html)之后,它将显示一个gravatar图像链接。0.gravatar.com/avatar/…但是当放置html变量时,它显示为空。如何修复此问题使用新的
wp.media
API而不是旧的thickbox
更改photo\u upload\u选项
功能如下
/*
photo upload option in widget
*/
function photo_upload_option($hook) {
if( $hook != 'widgets.php' )
return;
//enque Javasript Media API
wp_enqueue_media();
wp_enqueue_script( 'uploadphoto', get_template_directory_uri() . '/js/upload_image.js', array('jquery'), '1.0', 'true' );
}
用下面的代码替换整个upload_image.js
jQuery(function($){
// Set all variables to be used in scope
var frame,
addImgLink = $('.image_upload1'),
imgIdInput = $('.image1');
// ADD IMAGE LINK
addImgLink.on( 'click', function( event ){
event.preventDefault();
// If the media frame already exists, reopen it.
if ( frame ) {
frame.open();
return;
}
// Create a new media frame
frame = wp.media({
title: 'Select or Upload Image',
button: {
text: 'Use this Image'
},
multiple: false // Set to true to allow multiple files to be selected
});
// When an image is selected in the media frame...
frame.on( 'select', function() {
// Get media attachment details from the frame state
var attachment = frame.state().get('selection').first().toJSON();
// Send the attachment URL to our custom image input field.
//imgContainer.append( '<img src="'+attachment.url+'" alt="" style="max-width:100%;"/>' );
// Send the attachment id to our input field
imgIdInput.val( attachment.id );
});
// Finally, open the modal on click
frame.open();
});
});
jQuery(函数($){
//设置要在作用域中使用的所有变量
var框架,
addImgLink=$('.image_upload1'),
imgIdInput=$('.image1');
//添加图像链接
addImgLink.on('单击',函数(事件){
event.preventDefault();
//如果媒体框已存在,请重新打开它。
如果(帧){
frame.open();
返回;
}
//创建一个新的媒体框架
frame=wp.media({
标题:“选择或上载图像”,
按钮:{
文本:“使用此图像”
},
multiple:false//设置为true以允许选择多个文件
});
//在媒体框中选择图像时。。。
frame.on('select',function(){
//从帧状态获取媒体附件详细信息
var attachment=frame.state().get('selection').first().toJSON();
//将附件URL发送到我们的自定义图像输入字段。
//imgContainer.append(“”);
//将附件id发送到我们的输入字段
imgIdInput.val(附件.id);
});
//最后,单击打开模态
frame.open();
});
});
您能详细解释一下问题是什么吗?您在哪里设置了html
变量?我在你发布的代码中没有看到。嗨,拉维,当我在window.send_to_editor=function(html){var imagelink=jQuery('img',html.).attr('src');jQuery('.image1').val(imagelink);tb_remove();}中设置html变量时,在选择图像之后,我在文本字段中没有得到任何值。如果没有,则获得gravatar链接。我想在我选择的文本字段中的相关图像链接。非常感谢。我真的很感激你的好意。
