配置 config.js 文件

找到ckeditor目录下的config.js文件，添加两个配置

config.extraPlugins = \’uploadimage\’
config.filebrowserImageUploadUrl = \’/api/UploadImg/upload.php\’
//filebrowserImageUploadUrl 替换成你需要上传的接口

我们点击图片按钮时候，便发现弹窗中多了上传的tag界面，里面有选择文件按钮，可以上传图片到服务器，也就是会把file文件发送到上面设置的filebrowserImageUploadUrl接口。

upload.php 后端处理文件

TIPS：

1、ckedit4需要返回的json文件处理后续操作，使用json_encode；

2、$_REQUEST["ckCsrfToken"]是ckedit4需要的；

3、做了文件格式验证和文件大小处理；

4、文件名uniqid唯一处理。

<?php
$callback = $_REQUEST[\”ckCsrfToken\”];
$list=array(\”uploaded\”=>\’0\’,\’callback\’=>$callback);
$upaddress = \”/uploads/allimg/\”.strftime(\”%Y%m\”,time()).\”/\”;
echo upload();
function upload(){
global $list,$upaddress;
$callback = $_REQUEST[\”ckCsrfToken\”];
$extensions = array(\”jpg\”,\”bmp\”,\”gif\”,\”png\”);
$allowed_types = [\’image/jpeg\’, \’image/png\’, \’image/gif\’];
$uploadFilename = $_FILES[\’upload\’][\’name\’];
$uploadFilesize = $_FILES[\’upload\’][\’size\’];
$uploadFiletype = $_FILES[\’upload\’][\’type\’];
$extension = pathInfo($uploadFilename,PATHINFO_EXTENSION);
if(is_uploaded_file($_FILES[\’upload\’][\’tmp_name\’]) && $uploadFilesize < 1024*300 && in_array($uploadFiletype, $allowed_types) && in_array($extension,$extensions)){
$uploadPath = $_SERVER[\’DOCUMENT_ROOT\’].$upaddress;
if(!file_exists($uploadPath))
{
mkdir($uploadPath,0777,true);
}
$uuid = str_replace(\’.\’,\’\’,uniqid(\”\”,TRUE)).\”.\”.$extension;
$desname = $uploadPath.$uuid;
$tag = move_uploaded_file($_FILES[\’upload\’][\’tmp_name\’],$desname);
$list[\’uploaded\’]=1;
$list[\’fileName\’]=$uuid;
$list[\’url\’]=$upaddress.$uuid;
return json_encode($list);
}else{
$list[\’error\’]=\”文件类型不对或文件太大!\”;
return json_encode($list);
}
}
?>
