Changing a simple upload form to a multiple upload form

gibigbig · July 5, 2010

I have the following code that works fine:

<?php 
error_reporting(0);

$change="";
$abc="";


define ("MAX_SIZE","400");
function getExtension($str) {
         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
}

$errors=0;
  
if($_SERVER["REQUEST_METHOD"] == "POST")
{
	$image =$_FILES["file"]["name"];
$uploadedfile = $_FILES['file']['tmp_name'];
     

	if ($image) 
	{

		$filename = stripslashes($_FILES['file']['name']);

  		$extension = getExtension($filename);
		$extension = strtolower($extension);


if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
		{

			$change='<div class="msgdiv">Unknown Image extension </div> ';
			$errors=1;
		}
		else
		{

$size=filesize($_FILES['file']['tmp_name']);


if ($size > MAX_SIZE*1024)
{
$change='<div class="msgdiv">You have exceeded the size limit!</div> ';
$errors=1;
}


if($extension=="jpg" || $extension=="jpeg" )
{
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);

}
else if($extension=="png")
{
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);

}
else 
{
$src = imagecreatefromgif($uploadedfile);
}

echo $scr;

list($width,$height)=getimagesize($uploadedfile);


$newwidth=150;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);


$newwidth1=75;
$newheight1=($height/$width)*$newwidth1;
$tmp1=imagecreatetruecolor($newwidth1,$newheight1);

imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);

imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1,$width,$height);

srand ((double) microtime( )*1000000);
$random_number = rand( );
$filename = "rpg-avatar/".$random_number."_". $_FILES['file']['name'];

$filename1 = "rpg-avatar/small_".$random_number."_". $_FILES['file']['name'];



imagejpeg($tmp,$filename,100);

imagejpeg($tmp1,$filename1,100);

imagedestroy($src);
imagedestroy($tmp);
imagedestroy($tmp1);
}}

}

//If no errors registred, print the success message
if(isset($_POST['Submit']) && !$errors) 
{

   // mysql_query("update {$prefix}users set img='$big',img_small='$small' where user_id='$user'");
	$change=' <div class="msgdiv">Image Uploaded Successfully!</div>';
}

?>

But i would like to tweak it so that it there are two image upload forms and these two images are both resized and stored.

example:

what the script does now is:

form 1 => (processing) => resized image + thumb

what i want it to do is

form1 + 2 => (processing) => (resized image 1 + thumb 1) + (resized image2 + thumb2)

For the input file name put "[]" so it each new field gets an array key..

<input name="fileupload[]" type="file" id="fileupload[]"/>

And you can do this for the loop

while(list($key,$value) = each($_FILES[images][name]))

Try and learn the rest by doing trial and error. If you have more questions then come back to this thread and ask away, we'll be happy to help some more BUT only if you have made a legit effort... We won't write the entire code for you
