ThinkPHP combined with AjaxFileUploader to achieve refresh-free file upload,

The example in this article describes the method of using ThinkPHP combined with AjaxFileUploader to achieve refresh-free file upload. Share it with everyone for your reference. The specific implementation method is analyzed as follows:

First of all, the AjaxFileUploader plug-in is a plug-in based on jquery. We can use the AjaxFileUploader plug-in to realize the asynchronous file upload function. Don’t worry about compatibility issues when using this plug-in to upload files. Its compatibility can be said to be compatible with all mainstream browsers. Tools, let's introduce to you an example of AjaxFileUploader+thinkphp implementing file upload.

Using the AjaxFileUploader plug-in under the ThinkPHP framework to implement ajax file upload, supporting multiple file formats and uploading without page refresh.

Create the upAction.class.php file in the Lib/Action/ directory with the following code:

Copy code The code is as follows:

class upAction extends BaseAction{
public function index(){
    $this->display();
}
 
/*
*@文件上传
*@author    FineYi
*@date        2013-01-23
*/
public function upLoadFile(){
    $error = "";
    $msg = "";
    $fileElementName = 'fileToUpload';
    if(!empty($_FILES[$fileElementName]['error'])){
        switch($_FILES[$fileElementName]['error']){
            case '1':
                $error = 'The uploaded file exceeds the upload_max_filesize directive in php.ini';
                break;
            case '2':
                $error = 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form';
                break;
            case '3':
                $error = 'The uploaded file was only partially uploaded';
                break;
            case '4':
                $error = 'No file was uploaded.';
                break;
 
            case '6':
                $error = 'Missing a temporary folder';
                break;
            case '7':
                $error = 'Failed to write file to disk';
                break;
            case '8':
                $error = 'File upload stopped by extension';
                break;
            case '999':
            default:
                $error = 'No error code avaiable';
        }
    }elseif(empty($_FILES['fileToUpload']['tmp_name']) || $_FILES['fileToUpload']['tmp_name'] == 'none'){
        $error = 'No file was uploaded..';
    }else{
            $re = $this->up();
            if(!$re){
                $error = 'Up file fail';
            }
            $msg = $re['savename'];    //文件名
            $path = '/upload/bizcoop/'.$msg;    //文件路径
            $size = $re['size'];    //文件大小
    }       
    echo json_encode(array('error'=>$error,'msg'=>$msg,'path'=>$path,'size'=>$size));exit;
}
 
private function up(){
    import('@.Org.UploadFile');//将上传类UploadFile.class.php拷到Lib/Org文件夹下
    $upload=new UploadFile();
 
    $upload->maxSize='-1';//默认为-1，不限制上传大小
$upload->savePath= ICTSPACE_DIST_ROOT_PATH.'/www/upload/bizcoop/';//Save path
$upload->saveRule=uniqid;//File name saving rules for uploaded files
$upload->uploadReplace=true;//Whether to overwrite if a file with the same name exists
$upload->allowExts=array('jpg','jpeg','png','gif');//File types allowed to be uploaded
If($upload->upload()){
$info=$upload->getUploadFileInfo();
          return $info[0];
}else{
         return false;
exit;
}
}
}
?>
