Implementing attachment uploads using thinkphp

Just learned to use the thinkphp framework to simply upload attachments (Pictures, documents, videos and other files)

First you need to understand several functions in Upload.class.php (thinkphp/library/think/upload,class,php) in the TP frame

1:geterror () Get upload error message

2:uploadone () upload a single file

3:upload () Upload Multiple files

4:rootpath upload File Save root Path

The code is as follows

Front desk:

< TD > product picture </td><td>    <    type = "File" name = "Goods_pic"/>   </td>

Controller

//process Upload attachments image//Determine if upload 4: No attachments uploaded        if($_files[' Goods_pic '] [' Error ']<4) {                    //Upload          $cfg=Array(            ' RootPath ' = './public/uploads/',//Save Root Path          ); $upload=New\think\upload ($cfg);//fully qualified name instantiation object
When the Uploadone () method executes successfully, it returns information about the name and path of the attachment (on the server)          $file _info=$upload->uploadone ($_files[' Goods_pic ']); //save uploaded attachments to database stitching path//$upload->rootpath Gets the RootPath in the configuration through the __get () method in the parent class upload.class.php          $_post[' Goods_big_img ']=$upload->rootpath.$file _info[' Savepath '].$file _info[' Savename ']; }

If you have additional requirements for uploading attachments, refer to the parent class Upload.class.php in the Upload configuration config parameter to select the required parameters, just rewrite it in the Code $cfg=array () above!

The parent-class upload configuration parameters are as follows (can be rewritten according to your own requirements):

Private $config=Array(        ' Mimes ' =Array(),//file MIME types allowed for uploading' MaxSize ' = 0,//Upload file size limit (0-No limit)' Exts ' =Array(),//allow file suffixes to be uploaded' Autosub ' =true,//Automatic subdirectory Save file' SubName ' =Array(' Date ', ' y-m-d '),//How subdirectories are created, [0]-function name, [1]-parameter, multiple arguments using an array' RootPath ' = './uploads/',//Save Root Path' Savepath ' = ',//Save Path' Savename ' =Array(' uniqid ', '),//upload file naming rules, [0]-function name, [1]-parameter, multiple parameters using array' Saveext ' = ',//file save suffix, empty use original suffix' Replace ' =false,//exists if the same name overrides' Hash ' =true,//whether to generate a hash code' Callback ' =false,//detects if a file has a callback, if there is an array of returned file information' Driver ' = ',//File Upload driver' Driverconfig ' =Array(),//Upload Drive Configuration);
