resize and upload photo

jwk811 · April 29, 2010

ive tried so many scripts like this and for some reason it never works! can someone show me the most simplest way to do this please

You need to have GD installed on your PHP, do a:

echo phpinfo();

Scroll down until you see:

gd

GD Support enabled

GD Version bundled (2.0.34 compatible)

FreeType Support enabled

FreeType Linkage with freetype

FreeType Version 2.3.9

GIF Read Support enabled

GIF Create Support enabled

JPEG Support enabled

libJPEG Version 6b

PNG Support enabled

libPNG Version 1.2.37

WBMP Support enabled

XBM Support enabled

Once you install gd you should be able to use your scripts.

Not sure if this is helpful but a script I use to upload and resize images into three folders (original, thumb, large) is

<?php

    class imageValidator{
        //assigns $_FILES to short variables
        //constructor automatically runs when you make a new instance of the class, its a fresh copy.
        function __construct($files){
            $this->origfilename = $files['thePhoto']['name'];
            $this->tmpName = $files['thePhoto']['tmp_name'];
            $this->filesize = $files['thePhoto']['size'];
            $this->fileType = $files['thePhoto']['type'];
            $this->error = 0;
            $this->errormess = '';
            if(strlen($_POST['alt'])>0){
                $this->alt = $_POST['alt'];
            }
        }
        
//checks the file size.
        function checkFileSize(){
//set a max file           
            $maxfilesize = '3000000';
            if($this->filesize>$maxfilesize){
                $this->error = 1;
                $this->errormess .= 'Image file is too large.<br />';
            }

Of course this is my script so it also requires my form class to write the form and other includes from the website etc plus the database...but hopefully you can incoporate the 'imageValidator.php script and the following code to your page:

//check files with imagevalidator - size, extension, names...    
    $files = $_FILES;
    $check = new imageValidator($files);
    $check->checkFileSize();//this is checking the file size and if it exceeds it will send an error.
