In this paper, an example is given to describe the file uploading function with verification code by ThinkPHP. Share it for your reference. The specific implementation method is as follows:

ThinkPHP upload file is very simple we only need to call a file upload class UploadFile can quickly achieve upload function, I will give you a file upload need to verify the function of the example, I hope the article will help you.

In the template, we just need to call

<html>

<head>

<title> Verification code </title>

</head>

<body>

<formaction='__URL__/login'method='post'enctype="multipart/form-data">

 File upload :<inputtype='file'name='imgage'><br/>

 Verification code :<inputtype='text'name='verify'>

<imgsrc='__URL__/verify'onclick='change()'id='verify'/><br/>

<inputtype='submit'value=' Submit '>

</form>

</body>

</html>

php processing file

<?php

classIndexActionextendsAction{

/* Verification code */

publicfunctionverify(){

$type=isset($_GET['type'])?$_GET['type']:'gif';// If you do not set the picture format of the verification code , Default to gif Format 

import("@.ORG.Image");// Import picture out class 

Image::buildImageVerify(4,1,$type);// How many digits are there to set the verification code , It's a number , Or letters 

}

/* File upload */

publicfunctionupload(){

if(!empty($file))

import('@.ORG.UploadFile');// Import file upload class 

$file=newUploadFile();// Instantiation UploadFile Class 

// We can set the file upload 1 Attributes 

$file->maxSize=1000000;// Set the size of uploaded pictures 

$file->allowExtes=expload(',','jpg,jpeg,png,gif');// Set file upload format 

$file->savePath='/Tpl/default/Public/Uploads/';// Set the picture storage location 

$file->thumb='true';// Is it set to thumbnail 

$file->thumbPrefix='s_';// Set the prefix of thumbnail 

$file->thumbMaxWidth='400,100';// Set the maximum width of the picture 

$file->thumbMaxHeight='400,100';// Set the maximum height of the picture 

if($file->upload){

$list=$file->getUploadFileInof();// Get file upload information 

import('@.ORG.Image');

// Add a watermark to a picture 

Image::water($list[0]['savepath'].'s_'.$list[0]['savename'],'File/Tpl/defalut/Public/Images/logo.jpg');

}else{

$this->error($file->getErrorMsg());

}

$Model=M('Photo');

$data['image']=$_POST['image'];

$data['create_time']=time();

$vo=$Model->add($data);

if($vo!==false){

$this->success(" The picture was uploaded successfully !");

}else{

$this->error(" Picture upload failed ");

}

}

}

Simple Analysis 1 Example

import('@.ORG.UploadFile');// Import file upload class 

$file=newUploadFile();// Instantiation UploadFile Class

This is a direct call to the thinkphp file processing class, we do not need to do any operations.
In the upload process, it will be different from other classes

$Model=M('Photo');

$data['image']=$_POST['image'];

$data['create_time']=time();

$vo=$Model->add($data);

This $_ POST ['image'] is to get the name of our html file, this can be an array, that is, multi-file upload.

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