Method of Uploading File without Refresh Based on ThinkPHP and AjaxFileUploader

This paper describes the method of uploading files without refresh by ThinkPHP combined with AjaxFileUploader. Share it for your reference. The specific implementation method is analyzed as follows:

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

Under the framework of ThinkPHP, AjaxFileUploader plug-in is used to upload ajax files, which supports various file formats and uploads pages without refreshing.

Create the upAction. class. php file in the Lib/Action/directory as follows:

<?php

class upAction extends BaseAction{

public function index(){

    $this->display();

}

 

/*

*@ File upload 

*@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'];    // Filename 

            $path = '/upload/bizcoop/'.$msg;    // File path 

            $size = $re['size'];    // File size 

    }        

    echo json_encode(array('error'=>$error,'msg'=>$msg,'path'=>$path,'size'=>$size));exit;

}

 

private function up(){ 

    import('@.Org.UploadFile');// The class will be uploaded UploadFile.class.php Copy to Lib/Org Under the folder 

    $upload=new UploadFile();

 

    $upload->maxSize='-1';// Default to -1 Unlimited upload size 

    $upload->savePath= ICTSPACE_DIST_ROOT_PATH.'/www/upload/bizcoop/';// Save path 

    $upload->saveRule=uniqid;// File name saving rules for uploaded files 

    $upload->uploadReplace=true;// Do you want to overwrite if there is a file with the same name 

    $upload->allowExts=array('jpg','jpeg','png','gif');// File types allowed to upload 

    if($upload->upload()){

        $info=$upload->getUploadFileInfo();

        return $info[0];

    }else{

        return false;

        exit;

    } 

}

}

?>

Create the index. tpl file in the/Tpl/default/Up/ directory as follows:

<div id="content">

<h1>Ajax File Upload Demo</h1>

<img id="loading" style="display: none;" alt="" src="__APP____PUBLIC__/style/img/loading.gif" />

 

<form action="" enctype="multipart/form-data" method="POST" name="form">

<table class="tableForm" cellspacing="0" cellpadding="0">

<thead>

<tr>

<th></th>

</tr>

</thead>

<tbody>

<tr>

<td><input class="input" id="fileToUpload" type="file" name="fileToUpload" size="45" /></td>

</tr>

<tr>

<td><button class="button" id="buttonUpload" onclick="return ajaxFileUpload();">Upload</button></td>

</tr>

</tbody>

<tbody>

<tr>

<td><span> Uploaded attachments :</span></td>

</tr>

</tbody>

<tfoot></tfoot>

</table>

</form></div>

In the/Lib/Org directory under the ThinkPHP file upload class is OK, there are 1 plug-ins we need to download to the official.

I hope this article is helpful to everyone's PHP programming.
