Setting a max file size on upload?

[Solarpitch]

Hey Guys,

 

I am currently using the below script on my site. It works fine, the only propblem I have is that I havent set anything to catch a resize massive images. I want the script to catch images larger than 800px and resize them to something a little bit smaller.

 

Just wondering how I could add it to this script.

 

This script will take the current image and copy a thumbnail which will then be sent to the server. So how could I use it to catch large images and resize? I can use the resize() function and specify the height and width I want, I am just not sure how to do the rest.

 

$image1 = $_FILES['image1']['tmp_name'];

if($image1 != ""){$image1exists = 1; }
if($image1exists == 1){$image1file = $folder.$timest."AA".basename($_FILES['image1']['name']);}
if($image1exists == 1){$image1 = $folder.$timest."AA".basename($_FILES['image1']['name']);}

if($_FILES['image1']['tmp_name'] != ""){

			list($width, $height, $type, $attr) = getimagesize($_FILES['image1']['tmp_name']);

			move_uploaded_file($_FILES['image1']['tmp_name'], $image1file);

			$copy1 = $image1;

	        $destination_width    =    160;
   			$destination_height    =    110;

    			$imagecop1    =    new hft_image($copy1);
    			$sz=getimagesize($copy1);

    			$imagecop1->resize($destination_width,  $destination_height,  '-');
    			$image1thumb = $folder.$timest."AA"."THUMB.jpg";
    			$imagecop1->output_resized($image1thumb,  "JPEG");
}

Here is some script that I wrote in the past for this very function.  You will have to take the time to go through it and change it to your variable names...

 

<?php

//check the size of the file if need be shrink it down
$size = getimagesize($_FILES['image']['tmp_name']); // Get the image dimensions and mime type
$width = $size[0]; // Width of the image
$height = $size[1]; // Width of the image

if(($width > $height) && ($width > 480))
{
$height = (($height/$width) * 480);
$width = 480;
$resize = "true";
}

else if (($height > $width) && ($height > 360)) 
{
$width = (($width/$height) * 360);
$height = 360;
$resize = "true";
}

if ($resize == "true")
{
thumb($uploadFile, $height, $width, $uploadFile);
}
?>

 

Then I had a function called "thumb" that you can either place on the same page or use in like an includes page....

 

<?php
function thumb($source, $height, $width, $new_source) 
{ 
/* Check for the image's exisitance */ 
if (!file_exists($source)) 
{ 
	echo 'File does not exist!'; 
}

else
{ 
	$size = getimagesize($source); // Get the image dimensions and mime type
	$w = $width;
	$h = $height;
	$quality = "100";
	$resize = imagecreatetruecolor($w, $h); // Create a blank image

	/* Check quality option. If quality is greater than 100, return error */ 
	if ($quality > 100) 
	{
		echo 'The maximum quality is 100. Quality changes only affect JPEG images.';
	}

	else
	{
		//header('Content-Type: '.$size['mime']); // Set the mime type for the image

		switch ($size['mime'])
		{
			case 'image/jpeg':
			$im = imagecreatefromjpeg($source);
			imagecopyresampled($resize, $im, 0, 0, 0, 0, $w, $h, $size[0], $size[1]); // Resample the original JPEG
			imagejpeg($resize, $new_source, $quality); // Output the new JPEG
			break;

			case 'image/png':
			$im = imagecreatefrompng($source);
			imagecopyresampled($resize, $im, 0, 0, 0, 0, $w, $h, $size[0], $size[1]); // Resample the original PNG
			imagepng($resize, $new_source, $quality); // Output the new PNG
			break;
		}

		imagedestroy($im); 
	} 
} 
}

?>

 

Hopefully that helps you out.

Thanks mate!

Hey again guys,

 

I seem to be having trouble with memory when trying to run this piece of code. I have marked where the code fails and I seem to get the message

 

Allowed memory size of 33554432 bytes exhausted (tried to allocate 7584 bytes) in admin/thumbnail.inc.php on line 134

 

Is there anyway I can free up memory while running the script?

 

if($_FILES['image1']['tmp_name'] != ""){

			$copy1 = $image1;

			if(($width > $height) && ($width > 800))
			{
				$height = (($height/$width) * 800);
				$width = 800;

			else if (($height > $width) && ($height > 800))
