PHP upload only jpg, gif

Question

I 've been working with this file for a day now and I can
upload files but I want the user to be able to upload certain types
of files. Like jpg, gif or pdf. The number of items uploadable are
determined by a previous page submitted. Here is my code any help
would be greatly appreciated.
<?
// start of dynamic form
$uploadNeed = $_POST['uploadNeed'];
for($x=0;$x<$uploadNeed;$x++){
?>
<input name="uploadFile<? echo $x;?>" type="file"
id="uploadFile<? echo $x;?>">
</p>
<?
// end of for loop
?>
<p>
<input name="uploadNeed" type="hidden" value="<? echo
$uploadNeed;?>">
<input name="filename" type="hidden" id="filename" value="
<?
$UploadExts = array('gif','jpeg','jpg');
$uploadNeed = $_POST['uploadNeed'];
// start for loop
for($x=0;$x<$uploadNeed;$x++){
// strip file_name of slashes
$file_name = stripslashes($file_name);
$file_name = str_replace("'","",$file_name);
$file_name = $_FILES['uploadFile'. $x]['name']['type'];
$file_ext =
strtolower(substr($file_name,strrpos($file_name,".")));
//File Extension Check
if (!in_array($file_ext, $UploadExts))
$file_ext = substr(strtolower(strrchr($file_name,'.')),1);
$copy = copy($_FILES['uploadFile'.
$x]['tmp_name'],$file_name);
else
$message = "Sorry, $file_name($file_type) is not allowed to
be uploaded.";
// check if successfully copied
if($copy){
echo "$file_name | uploaded Successfully!><br>";
}else{
echo "$file_name | Could Not Be Uploaded!<br>";
// end of loop
?>">

im afraid not...
I've been googlin for a solution for this problem for some time, and i got nothing!
All that i got was that there is a property for the "file" html input component that's called "accept" which you can add a list of MIME types that you want to be listed in the upload file dialog... But the funny thing is... Its only in the W3C standard an none of the current browsers support it till now!!!! = |
The only solution that they gave till now, is to use javascript to check the file name value when submitting the form and make sure that the extension is like what you want, else report it in an alertbox for the user that he change the file type cause its not supported! How absurd! =/
If anyone could find a solution for this thing, i'll be happy to know...
