Question

I’m reading this line in Linux. However, when I’m echoing this in the browser, nothing shows up. Is there something wrong with how I used the echo line?

// relevant code snippets
$mypic = $_FILES['upload']['name'];
$temp = $_FILES['upload']['tmp_name'];
$type = $_FILES['upload']['type'];

/*$finfo=finfo_open(FILEINFO_MIME_TYPE);
$type=finfo_file($finfo,$temp);
finfo_close($finfo);*/

echo "<pre>"; print_r($_FILES);
echo $mypic."<br />";
echo $type."<br />";
echo $_FILES['upload']['error']."<br />";
echo var_dump($type)."<br />";

If you suspect something is wrong with how I’m handling file inputs in another file, I’ve included that php file in this link.

<form ENCTYPE="multipart/form-data" method="post" action="insert.php">

Name: <input type="text" name="name" maxlength="15" /><br />
Email: <input type="text" name="email" maxlength="30" /><br />
Password: <input type="password" name="password" maxlength="15" /><br />
Confirm Password: <input type="password" name="cpassword" maxlength="15" /><br />

<input type="hidden" name="MAX_FILE_SIZE" value="10000">
Choose your picture: <input type="file" name="upload"><p>
<input type="submit" name="submit" value="Register" /><br />

<p>
<center><h3><?php include("links.php"); ?></h3></center>

</form>

Here is the printout that I’m seeing:

Array (
[upload] => Array
(
[name] => protest.jpg
[type] =>
[tmp_name] =>
[error] => 2
[size] => 0
)

) protest.jpg

2 string(0) “”

I tried an icon and found no problems other than permissions settings (I think I can solve this on my own for the time being). However, I’m still stuck on setting the file size. I followed Peter Stuart’s instructions and got the following printout:

Apparently, the file size limits in these two settings are more than enough to handle the original images I had (which are under 200 kb). I don’t know what more I can do in this case.

Answer 1

The file type is empty for the same reason that the filesize is 0 and the error is 2.

From Error Messages Explained:

UPLOAD_ERR_FORM_SIZE Value: 2; The uploaded file exceeds the
MAX_FILE_SIZE directive that was specified in the HTML form.

You have your max size set to 10000, which is in bytes, so that’s roughly 10Kb. If it’s a photo taken on any modern digital cam (over 4mgpx) it will probably need to be at least ten times that size. Just leave out the max size for now until you get a rough average of the image size people are submitting. PHP has a max upload size of its own to avoid tying up the line for too long.

To avoid issues like this in the future (not knowing if the file upload was successul), you probably want to wrap your code in something like:

$upload_error[0] = "AOK";
$upload_error[1] = "Server says: File too big!";
$upload_error[2] = "Browser says: File too big!";
$upload_error[3] = "File upload didn't finish.";
$upload_error[4] = "Ummm.... You forgot the file.";
$upload_error[6] = "Oops.  Webmaster needs to fix something.";
$upload_error[7] = "Server says: I'm stuffed. Email webmaster.";
$upload_error[8] = "Server says: Not gonna do it.  Webmaster needs to fix something.";


if($_FILES['upload']['error'] == 0) {
   //do your thing and move it to the database.
} else {
    $error_num = $_FILES['upload']['error'];
    echo $upload_error[$error_num];
}
