php file upload strange error

Question

Why php give to me error of file upload?

<?php

   if($_FILES["filename"]["size"] > 1024*25*1024)
   {
     $message = 'file must be less, than 25 mb';
     exit;
   }

   if(is_uploaded_file($_FILES["filename"]["tmp_name"]))
   {

     move_uploaded_file($_FILES["filename"]["tmp_name"], "share/".$_FILES["filename"]["name"]);

     $message = 'succesfull!';
   } else {
      $message = 'Error upload file';
   }


?>

form with enctype = 'multipart/form-data'

in php.ini i have got

upload_max_file_size: 25 mb Max_post_data = 25mb upload_tmp_dir = /tmp

Why it does not work?

Use var_dump($_FILES); instead of pointless Error upload file and see — zerkms

If is_uploaded_file() fails, then PHP doesn't know why the upload failed. It just knows that it did. The only thing I can think of to check is that there is enough space on /tmp. — staticsan

If you do a print_r on $_FILES, you will see an error code. The meaning of the error code can be found here:

there is no error: array(1) { ["file"]=> array(5) { ["name"]=> string(17) "1326889022150.jpg" ["type"]=> string(10) "image/jpeg" ["tmp_name"]=> string(14) "/tmp/phpvS3WCa" ["error"]=> int(0) ["size"]=> int(35993) } }

The name of your file input is file or filename? If its the former, then change your above code to: $_FILES['file']['tmp_name'] INSTEAD OF $_FILES['filename']['tmp_name']

<div id="form"> <form action = "upload.php" method = "post" enctype = 'multipart/form-data'> Выберите файл: <input type="file" name="file" /><br /><br /> <input type="submit" class="button red" value="Отправить файл на сервер" /> </form>

Use $_FILES['file']['tmp_name']

Verify that your php.ini setting looks like this:

upload_max_file_size=25M

Common Errors include:

upload_max_file_size = 0.25M     // Must be an integer

upload_max_file_size = 25M       // No spaces around equal sign

upload_max_file_size=25MB        // Use M not MB

;upload_max_file_size=25M        // Semicolon in front comments out the line.

Restart server after changing php.ini.

if your content length is greater then max post size, you should use exception handler or you should put this code to top code.

if ($_SERVER['REQUEST_METHOD']=='POST' && empty($_POST) && isset($_SERVER['CONTENT_TYPE']) && substr($_SERVER['CONTENT_TYPE'],0,19)=='multipart/form-data')
{
    if ($_SERVER['CONTENT_LENGTH']>1024*1024*25)
    {
        $message = 'file must be less, than 25 mb';
                exit;
    }
}
