checking file extensions for upload

bryanptcs · December 19, 2006

Ok, I had the below code to check file extensions. I have changed my upload code to handle more than 1 upload at a time, however in doing that, the pathinfo() is no longer reading 1 file name, it is reading an array and thus causing errror.

Here is my original code for checking extensions:

[code]
$allowed_ext = "jpg, gif, png, pdf, txt, psd, ai, doc, zip, rar, gz, jpeg"; // These are the allowed extensions of the files that are uploaded
// Check Entension
$extension = pathinfo($_FILES['file']['name']);
$extension = $extension[extension];
$allowed_paths = explode(", ", $allowed_ext);
for($i = 0; $i < count($allowed_paths); $i++) {
if ($allowed_paths[$i] == "$extension") {
$ok = "1";
}
}
[/code]

I use this for multiple uploads and file and size checks. change if to your liking
[code]<?php
$absolute_path = "/home/theeenr8/public_html/misc"; //Absolute path to where files are uploaded
$size_limit = "yes"; //do you want a size limit yes or no.
$limit_size = "600000"; //How big do you want size limit to be in bytes
$limit_ext = "yes"; //do you want to limit the extensions of files uploaded
$ext_count = "1"; //total number of extensions in array below
$extensions = array(".jpg"); //List extensions you want files uploaded to be

if(!isset($_POST['submit'])){

if (($extensions == "") or ($extensions == " ") or ($ext_count == "0") or ($ext_count == "") or ($limit_ext != "yes") or ($limit_ext == "")) {
$extens = "any extension";
} else {
$ext_count2 = $ext_count+1;
for($counter=0; $counter<$ext_count; $counter++) {
$extens = "  $extensions[$counter]";
}
}
if (($limit_size == "") or ($size_limit != "yes")) {
$limit_size = "any size";
} else {
$limit_size .= " bytes";
$mb_size = ($limit_size/1000000);
}
$pichead = "<li><font size=\"2\" color=660000>File extension must be $extens<b>";
$pichead .="</b></font>
<li><font size=\"2\" color=660000>Maximum file size is $limit_size ($mb_size MB)</font></li>
<li><font size=\"2\" color=660000>No spaces in the filename</font></li>";
