PHP upload form doesn't accept .pdf

Question

For some reason, my PHP-upload field doesn't accept pdf-files. I don't get it cause I thought there is no selection made while uploading the file... Any advice?

$name = $_FILES["uploadedfile"]["name"];
$tmp_name = $_FILES["uploadedfile"]["tmp_name"];
$add = "downloads/lkverslagen/".$name;

move_uploaded_file($tmp_name, $add);

if(file_exists("downloads/lkverslagen/$name")) {

    $lkverslag = new LKverslag();
    $jaar = date (Y);

    $lkverslag->titel           = $titel;
    $lkverslag->datum           = $datecorrect;
    $lkverslag->link            = $name;
    $lkverslag->jaar            = $jaar;
    $lkverslag->auteur          = $_SESSION['user']['naam'];
    $lkverslag->teller          = $_POST['titel'];

    if ($lkverslag->saveverslag($_DB)) {
        $feedback = "OK";
    } else {
        $feedback = "NOT OK";
    }
} else {
    $feedback = "ERROR";
}

Answer 1

So, to repeat my comment: there are limits on the allowed size of uploaded files -- the PDF file might simply be too large.

Answer 2

Here are some things to check:

• Ensure that your file upload and post limits are not reached by editing upload_max_filesize and post_max_size in your .htaccess or php.ini file. If you have error reporting on, you should see an error when they're reached. See this: http://drupal.org/node/97193

• Check for file upload error codes. See the documentation for these: http://www.php.net/manual/en/features.file-upload.errors.php

• Ensure that your memory_limit has not been reached. Again, with error logging enabled, you should receive an error message about this. http://drupal.org/node/207036

• Check PHP's common pitfalls documentation and make sure there's nothing there that helps: http://www.php.net/manual/en/features.file-upload.common-pitfalls.php

If none of this helps, enable error reporting and post what you receive so we can tailor our answers better to your situation.
