Loops
Hi all, I am working on a image upload/resize/watermark script, but I am slightly stuck! I started with a script that only allows you to upload one file at a time and modified it to do all the stuff I needed, but now it has the option to upload more than one file, but I dont know how to tell the PHP bit to loop through for each of the files that have been selected.
Here is the code I am using:
Thanks in advance for any helpPHP Code:<?php
require_once 'watermark.php';
$idir = "large/"; // Path To Images Directory
$tdir = "thumbs/"; // Path To Thumbnails Directory
$wdir = "watermarked/"; // Path to watermarked image
$twidth = "200"; // Maximum Width For Thumbnail Images
$theight = "150"; // Maximum Height For Thumbnail Images
if (!isset($_GET['subpage'])) { // Image Upload Form Below
?>
<script language="javascript">
var upload_range = 1;
// Add one upload slot
function addUploadSlot(num){
if(num == upload_range){
var up = document.getElementById('upload_slots');
var dv = document.createElement("div");
dv.innerHTML = '<input type="file" onChange="addUploadSlot('+(upload_range + 1)+')" name="imagefile[' + (upload_range + 1) + ']" class="form">Yes<input type="checkbox" name="watermark[' + (upload_range + 1) + ']" value="yes">';
up.appendChild(dv);
upload_range++;
up = null;
dv = null;
}
}
</script>
<form method="post" action="index.php?subpage=upload" enctype="multipart/form-data">
<table width="37%" border="0">
<tr>
<td width="60%">File</td>
<td width="40%">Watermark?</td>
</tr>
<tr>
<td colspan="2"><div id="upload_slots"><input type="file" onChange="addUploadSlot(1)" name="imagefile[1]" >Yes<input type="checkbox" name="watermark[1]" value="yes"></div></td>
</tr>
</table>
<p>
<input name="submit" type="submit" value="Upload">
<input type="reset" value="Clear" class="form">
</p>
</form>

if ($_FILES['imagefile']['type'] == "image/jpg" || $_FILES['imagefile']['type'] == "image/jpeg" || $_FILES['imagefile']['type'] == "image/pjpeg") {
$file_ext = strrchr($_FILES['imagefile']['name'], '.'); // Get The File Extention In The Format Of , For Instance, .jpg, .gif or .php

$zoom = $twidth / $currheight; // Length Ratio For Width
$newheight = $theight; // Height Is Equal To Max Height
$newwidth = $currwidth * $zoom; // Creates The New Width
} else { // Otherwise, Assume Width Is Greater Than Height (Will Produce Same Result If Width Is Equal To Height)
$zoom = $twidth / $currwidth; // Length Ratio For Height
$newwidth = $twidth; // Width Is Equal To Max Width

}

imagejpeg($dimg, "$tdir" . $url); // Saving The Image
imagedestroy($simg); // Destroying The Temporary Image
imagedestroy($dimg); // Destroying The Other Temporary Image
print 'Image thumbnail created successfully'; // Resize successful
} else {
print '<font color="#FF0000">ERROR: Unable to upload image.</font>'; // Error Message If Upload Failed
}
} else {
print '<font color="#FF0000">ERROR: Wrong filetype (has to be a .jpg or .jpeg. Yours is '; // Error Message If Filetype Is Wrong
print $file_ext; // Show The Invalid File's Extention
print '.</font>';
