PHP / CodeIgniter - $_FILES being ignored completely

I have the following in my view

<input class="file" name="mpfile[]" type="file" size="32" />

In my controller, i have the following code.

if(isset($_FILES['mpfile'])) {
    echo 'testing';
}

Fairly simple yes? .... E开发者_StackOverflow中文版xcept that every time i run it, no matter if i have choosen a file or not, it runs ... Should it only run the echo if i have a file ready for input?

Make sure your FORM element has the following attributes:

method="POST"

and

enctype="multipart/form-data"

check your PHP.ini for:

file_uploads = "1"
post_max_size = 50000
upload_max_file_size = 2M

do a phpinfo();

disclaimer php.ini values might be slightly off, but you'll find them I'm sure. the names are right, not sure if the values are.

Assuming the <input> is embedded in a <form> that does a POST on your script, have you tried dumping $_FILES? E.g.:

if ('POST' == $_SERVER['REQUEST_METHOD'])
  {
     print '<pre>'.var_export($_FILES,TRUE).'</pre>';
  }

Can you post a result? Also, are uploads enabled for PHP?

Have you tried using Codeigniter's upload class. Codeigniter could be emptying $_FILES along with the other globals.

Maybe try dumping $_FILES at the top of codeigniters index.php to make sure

  if(isset($_FILES['mpfile']['name']) && $_FILES['mpfile']['name'])
  {
    echo 'testing';
   }

Here's another stab in the dark. Check the error code:

if($_FILES['mpfile']['error'] != UPLOAD_ERR_NO_FILE) {
     echo 'testing'; 
}

You also need to check for an empty file:

if (isset($_FILES['userfile']) && $_FILES['userfile']['error'] != 4)

See this post:

http://codeigniter.com/forums/viewthread/136610/#673652

"The upload field gets put into $_FILES even if it is empty and the error and size are set to 4 and 0 respectively"

Edit to add:

I've never uploaded multiple, but I think in your case you would add ['mpfile'] before each ['userfile'] in the test

if (!empty($_FILES['mpfile']['name'])) {
    var_dump($_FILES['mpfile']['name']);
}

You are defining an array:

<input class="file" name="mpfile[]" type="file" size="32" />

In PHP the variable $_FILES['mpfile'] will be also an (empty) array. If you now test with isset then it is set because it's an array (and never null).

Test with empty().
