Uploading Files

[steve-t]

Further to an earlier thread that was unresolved, I need a script that checks if an uploaded file has either a .PDF or .PPT file extension and if not displays an error message.

Any help will be VERY much appreciated!  :)

[code]<?php
$arr = explode('.',$filename);
$ext = $arr[count($arr)-1];

if(in_array(strtolower($ext),array('pdf','pdt'))
{
// do stuff
}
else {
echo "Invalid filetype";
}
?>[/code]

This should work.

You will need to change name to the value of name from your form.
[CODE]<?php
if($_FILES['name']['type'] == 'application/PDF' || $_FILES['name']['type'] == 'application/PPT'){
    //Upload the files
}else{
    //Don't upload the files
}
?>[/CODE]

you could put the extensions into an array and some variables

[code]$limit_ext = "yes"; //do you want to limit the extensions of files uploaded
$ext_count = "2"; //total number of extensions in array below
$extensions = array(".pdf", ".ppt"); //List extensions you want files uploaded to be[/code]

Then check if they fall into the array
[code]$ext = strrchr($file_name,'.');
if (($limit_ext == "yes") && (!in_array($ext,$extensions))) {
echo "File is wrong type";
}else{
// place your code here

}
?>[/code]

The Little Guy: It is different what mime-type a browser will send. That might work in some browsers, but maybe not in all.

I thought that was a server thing, but after looking at the manual, I guess not, maybe this:
[CODE]
<?php
function file_extension($filename)
{
    $path_info = pathinfo($filename);
    return $path_info['extension'];
}
if(file_extension($_FILES['name'])=="PDF" || file_extension($_FILES['name'])=="PPT"){
//upload file
}else{
//dont upload
}?>[/CODE]
