Image upload.

[justAnoob]

Hi,,, the image upload script that I'm using works fantastic(I think) for 1 image..Now lets say I have 5 file field boxes. What would be the easiest way to loop through all 5 boxes for upload?? Can someone get me started?

 

<?php
session_start();
include "connection.php";
mysql_connect("$host", "$username", "$password") or die("Could not connect.");
mysql_select_db("$db_name") or die("Could not find database");
$item_name = mysql_real_escape_string($_POST['item_name']);
$description = mysql_real_escape_string($_POST['description']);
$in_return = mysql_real_escape_string($_POST['in_return']);

define ("MAX_SIZE","1000");
function getExtension($str)
{
$i = strrpos($str,".");
if (!$i)
{
	return "";
}
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
$errors=0;
if(isset($_POST['submit']))
{
$image=$_FILES['image']['name'];
if($image) 
{
	$filename = stripslashes($_FILES['image']['name']);
	$extension = getExtension($filename);

	$extension = strtolower($extension);
	if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "gif") && ($extension != "png"))
	{
		$_SESSION['badformat'] = "Your picture must be a .JPG .GIF or .PNG";
		header("location: http://www.---------.com/---------.php");
		exit();
		$errors=1;
	}
	else
	{
		$size=filesize($_FILES['image']['tmp_name']);
		if ($size > MAX_SIZE*1024)
		{
			$_SESSION['toobig'] = "Your picture can not exceed 1 megabyte.";
			header("location: http://www.---------.com/---------.php");
			exit();
			$errors=1;
		}

		$category = $_POST['listmenu'];
		$image_name=time().'.'.$extension;
		$newname="userimages/$category/".$image_name;
		$copied = copy($_FILES['image']['tmp_name'], $newname);
		if (!$copied)
		{
			$_SESSION['notcopy'] = "There was an error posting your trade. Please try again later.";
			header("location: http://www.-------.com/--------.php");
			exit();
			$errors=1;
		}
	}
}
}
// if everything is good, post new item for the user
$mysqlcategory = $category;
$imgpath = $newname;
$findit = $_SESSION['id'];
$result=mysql_query("SELECT id FROM members WHERE username = '$findit'");
$row=mysql_fetch_assoc($result);
$user_id = $row['id'];
$sql = "INSERT INTO abcxyz(item_name, description, in_return, imgpath, category, user_id)VALUES('$item_name','$description','$in_return', '$imgpath', '$mysqlcategory', '$user_id')";
mysql_query($sql) or die(mysql_error());
// go to confirmation page if upload is completed.
if(isset($_POST['submit']) && !$errors)
{
$_SESSION['picload'] = $newname;
$_SESSION['picname'] = $item_name;
header("location: http://www.-----------.com/---------.php");
exit();
} 
?>

Also,, when I add the extra file fields to my form,, should they be named the same,, or different?? I was thinking the same name so the script can cycle through all the file fields. Maybe with a Foreach statement??

You could use

foreach($_FILES as $key => $value)
{
//your processing
}

You'll have to refer to $_FILES['filename'] as $_FILES[$key] though.

Could you explain a tad bit more ??

[jackpf]

Ok, $_FILES as an array. For each file uploaded, that filename (name of the form element) is put into the array. So, if you use foreach(), you can go through each file, and do whatever you want with it.

I'm still confused,, I'll just play around with it. And look for some examples..

[jackpf]

What are you confused with?
