PHP100 excellent: Support for thumbnails for PHP Upload

// First create an upload class named uploadclassUpLoad {public $ error =; pubic $ uploadFile =; public $ mimeType = text/plain; public $ fiterType = array (); public $ Filter =; public $ fileSiz

Instance:

1. create the file upfile. php. the code is as follows:

// If a parameter is received from the form, upload the parameter; otherwise, the form is displayed.

If (isset ($ _ FILES ['uploadinput']) {

// Create a directory function. The $ directoryName parameter does not end "/",

// If yes, when '/' is split as an array, a null value is displayed.

Function makeDirectory ($ directoryName ){

$ DirectoryName = str_replace ("\", "/", $ directoryName );

$ DirNames = explode ('/', $ directoryName );

$ Total = count ($ dirNames );

$ Temp = '';

For ($ I = 0; $ I <$ total; $ I ++ ){

$ Temp. = $ dirNames [$ I]. '/';

If (! Is_dir ($ temp )){

$ Oldmask = umask (0 );

If (! Mkdir ($ temp, 0777) exit ("You cannot create a directory $ temp ");

Umask ($ oldmask );

}

}

Return true;

}

If ($ _ FILES ['uploadinput'] ['name'] <> ""){

// Contains the uploaded file class

Require_once ('class _ upload. php ');

// Set the file upload Directory

$ SavePath = "upload ";

// Create a directory

MakeDirectory ($ savePath );

// Allowed file types

$ FileFormat = array ('GIF', 'jpg ', 'jpg', 'PNG ');

// File size limit; unit: Byte, 1KB = 1000 Byte // php100.com

// 0 indicates no limit, but it is affected by the upload_max_filesize setting in php. ini.

$ MaxSize = 0;

// Overwrite the original file? 0 is not allowed. 1 is allowed.

$ Overwrite = 0;

// Initialize the upload class

$ F = new clsUpload ($ savePath, $ fileFormat, $ maxSize, $ overwrite );

// If you want to generate a thumbnail, call the member function $ f-> setThumb ();

// Parameter list: setThumb ($ thumb, $ thumbWidth = 0, $ thumbHeight = 0)

// $ Thumb = 1 indicates that a thumbnail is to be generated. when not called, the value is 0.

// $ ThumbWidth: width of the thumbnail. unit: Pixel (px). if it is left blank, the default value is 130.

// $ ThumbHeight the Thumbnail height in pixels (px). if it is left blank, the default value is 130.

$ F-> setThumb (1 );

// The uploadinput parameter is the name of the input field of the file to be uploaded in the form.

// The value 0 indicates that the file name is not changed. if it is 1, a random file name is generated by the system.

If (! $ F-> run ('uploadinput', 0 )){

// You can only get the last error message through $ f-> errmsg,

// Detailed information can be obtained in $ f-> getInfo.

Echo $ f-> errmsg ()."
\ N ";

}

// Save the upload result in the array returnArray. // Php100.com

Echo"

";
 
　　print_r($f->getInfo());
　　echo "

";

 

}

} Else {

?>

　　

Send this file:
 

　　
 

　　
 

　　
 

　　
 

　　

2. create the file class_upload.php. the code is as follows:

　　

Class clsUpload {

Var $ saveName; // save the name

Var $ savePath; // save path

Var $ fileFormat = array ('GIF', 'jpg ', 'Doc', 'application/octet-stream'); // File Format & MIME limitation

Var $ overwrite = 0; // overwrite mode

Var $ maxSize = 0; // maximum file bytes

Var $ ext; // file extension

Var $ thumb = 0; // whether to generate a thumbnail

Var $ thumbWidth = 130; // Thumbnail width

Var $ thumbHeight = 130; // The height of the thumbnail.

Var $ thumbPrefix = "_"; // the prefix of the thumbnail.

Var $ errno; // error code

Var $ returnArray = array (); // return information of all objects

Var $ returninfo = array (); // information returned for each file

// Constructor

// @ Param $ savePath file storage path

// @ Param $ fileFormat file format limit array

// @ Param $ maxSize maximum file size

// @ Param $ overwriet indicates whether to overwrite 1. overwrite 0.

Function clsUpload ($ savePath, $ fileFormat = '', $ maxSize = 0, $ overwrite = 0 ){

$ This-> setSavepath ($ savePath );

$ This-> setFileformat ($ fileFormat );

$ This-> setMaxsize ($ maxSize );

$ This-> setOverwrite ($ overwrite );

$ This-> setThumb ($ this-> thumb, $ this-> thumbWidth, $ this-> thumbHeight );

$ This-> errno = 0;

}

// Upload

// @ Param $ fileInput name of input in Form

// @ Param $ changeName whether to change the file name

Function run ($ fileInput, $ changeName = 1 ){

If (isset ($ _ FILES [$ fileInput]) {

$ FileArr = $ _ FILES [$ fileInput];

If (is_array ($ fileArr ['name']) {// upload multiple files with the same file domain name

For ($ I = 0; $ I <count ($ fileArr ['name']); $ I ++ ){

$ Ar ['tmp _ name'] = $ fileArr ['tmp _ name'] [$ I];

$ Ar ['name'] = $ fileArr ['name'] [$ I];

$ Ar ['type'] = $ fileArr ['type'] [$ I];

$ Ar ['size'] = $ fileArr ['size'] [$ I];

$ Ar ['error'] = $ fileArr ['error'] [$ I];

$ This-> getExt ($ ar ['name']); // Obtain the extension and assign it to $ this-> ext. it will be updated in the next loop.

$ This-> setSavename ($ changeName = 1? '': $ Ar ['name']); // sets the file name to be saved.

If ($ this-> copyfile ($ ar )){

$ This-> returnArray [] = $ this-> returninfo;

} Else {

$ This-> returninfo ['error'] = $ this-> errmsg ();

$ This-> returnArray [] = $ this-> returninfo;

}

}

Return $ this-> errno? False: true;
