Automatic Upload to folders based on extension

[DssTrainer]

Hi,

I'm trying to make my upload script automatically upload to a certain folder based on the file extension. e.g.: jpg files to upload to the "jpg" folder, zip files to upload to the "zip" folder, etc.

Currently I have it working that it uploads to a folder that the user selects, but if the user selects the wrong folder, then its more maintenance I have to deal with.

Here is the current code:

<form id="UploadForm" action="index.php" method="post" enctype="multipart/form-data">
    <div> 
      <h1>Select your files</h1>
      {loop name=i var=$upload_fields}<strong>{$upload_fields[i]}</strong>. 
      <input type="file" name="file{$upload_fields[i]}" size="70" style="margin-bottom: 3px"/>
      <br />
      {/loop} <br />
      ____
      <input type="image" src="images/upload.gif" name="action[doupload]" />
    </div>
    <div> <br />
      <h1>Upload options</h1>
	Upload into: <strong id="selected_destination">Maps</strong><br />
      <select name="destination" cols="50" id="destination" onchange="document.getElementById('selected_destination').innerHTML = this.value;">
	{loop name=j var=$incoming_directories}
	    <option value="{$incoming_directories[j]}">{$incoming_directories[j]}</option>
	{/loop}
      </select>
      <br />
      <br />

above where you see the "Upload into:" thats where you have the select. I would like it to just upload based on "if{ext == .jpg} 'upload into JPG directory'"

I've searched for examples here but didn't quite find any.

Hi,

Have a lok at the substr and strlen functions: they will give you the length f a string, and the option to create substrings. From that, you should be able to extract t;he extention of a filenam.

$thisname="mfilename.jpg"

$extention = substr(thisname,  -3);
