picture extension

[web_master]

hi,

 

I want to reload the picture, but, what if I don't know the extension?

 

example:

if in folder is a files like

 

1_mainphoto_th.jpg

2_mainphoto_th.gif

3_mainphoto_th.png

 

<?php 
$photo_dest = "./up_main/".$request['main_id']."_mainphoto_th" ????
?>

Why wouldn't you know the extension?

 

You could just do something like:

 

$exts = array('jpg', 'png', 'jpeg', 'gif', 'bmp');

 

foreach($exts as $ext) if(file_exists("./up_main/".$request['main_id']."_mainphoto_th".$ext)) { $photo_dest = "./up_main/".$request['main_id']."_mainphoto_th".$ext; break; }

 

Thats about all you can do, since yout not trying to figure out the file type, you are trying to guess the file name.
