PHP利用CKEditor上传图片

根据我转载的那篇关于CKEditor上传图片的文章，试了一下。现将过程记录如下。

首先，得先下载CKEditor，下载的地址：http://ckeditor.com/。我下载的是standard版。

1.去掉预览中的文字

在ckeditor/plugins/image/dialogs/image.js

搜索“b.config.image_previewText”，把(b.config.image_previewText||'')单引号中的内容全删了。

2.开启上传功能

还是image.js这个文件，搜索“upload”可以找到这一段

id:'Upload',hidden:true

实际上上传功能被隐藏了，把上面的true改成false。

3.定义上传图片时的action

在ckeditor/config.js中加入：

config.filebrowserUploadUrl = '/back/upload';

4.在BackAction中加入upload方法（我用的是ThinkPHP3.0）;

//upload image from ckeditor
public function upload(){
$extensions = array("jpg","bmp","gif","png");
$uploadFilename = $_FILES['upload']['name'];
$extension = pathInfo($uploadFilename,PATHINFO_EXTENSION);
if(in_array($extension,$extensions)){
$uploadPath = str_replace("\\",'/',realpath(__ROOT__))."/uploads/";
$uuid = str_replace('.','',uniqid("",TRUE)).".".$extension;
$desname = $uploadPath.$uuid;
$previewname = '/uploads/'.$uuid;
$tag = move_uploaded_file($_FILES['upload']['tmp_name'],$desname);
$callback = $_REQUEST["CKEditorFuncNum"];
echo "<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction($callback,'".$previewname."','');</script>";
}else{
echo "<font color=\"red\"size=\"2\">*文件格式不正确（必须为.jpg/.gif/.bmp/.png文件）</font>";
}
}
