$_POST not working

[Meridius]

Hello,

 

I am trying to pass variables to a page, should be an easy job you say? Same thoughts here but i can't really find the problem.

For starters I have a simple form with a textfield and a upload field. (i'm a dutchy so labels/errors will be foreign to most)

<form action="upload_exec.php" method="post" enctype="multipart/form-data">
<table border="0">
<tr>
	<td>Mapnaam:</td>
	<td><input type="text" name="folder" size="35" /></td>
</tr>
<tr>
        <td>Bestanden:</td>
	<td><input type="file" name="file[]" id="file" multiple=""/></td>
</tr>
<tr>
	<td colspan="2" align="right"><input type="submit" name="submit" value="Submit" /></td>
</tr>
</table>
</form>

 

Basically i can't see anything wrong with it, on the form action page i constantly get the error message saying the variable isn't filled.

<?php
include('ResizeImage.php');

if (!isset($_POST['folder'])) 
{
	echo "Er is geen map aangegeven";
}
else 
{
	$dirname = $_POST["folder"];
	$filename = ('./' . $dirname . '/');

	if (!file_exists($filename)) 
	{
		mkdir("{$dirname}");
	}

	for($i = 0; $i < count($_FILES['file']['name']); $i++)
	{
		$allowedExts = array("jpg", "JPG", "jpeg", "JPEG", "gif", "GIF", "png");
		$extension = end(explode(".", $_FILES["file"]["name"][$i]));
		if ((($_FILES["file"]["type"][$i] == "image/gif")
		|| ($_FILES["file"]["type"][$i] == "image/GIF")
		|| ($_FILES["file"]["type"][$i] == "image/jpeg")
		|| ($_FILES["file"]["type"][$i] == "image/JPEG")
		|| ($_FILES["file"]["type"][$i] == "image/pjpeg")
		|| ($_FILES["file"]["type"][$i] == "image/PJPEG"))
		&& ($_FILES["file"]["size"][$i] < 200000000)
		&& in_array($extension, $allowedExts))
		{
			if ($_FILES["file"]["error"][$i] > 0)
			{
				echo "Foutode: " . $_FILES["file"]["error"][$i] . "<br />";
			}
			else
			{					
				if (file_exists("" . $dirname . "/" . $_FILES["file"]["name"][$i]))
				{
					echo $_FILES["file"]["name"][$i] . " already exists. <br />";
				}
				else
				{
					move_uploaded_file($_FILES["file"]["tmp_name"][$i],
					"" . $dirname . "/" . $_FILES["file"]["name"][$i]);
					echo "Opgeslagen in: " . "" . $dirname . "/" . $_FILES["file"]["name"][$i] . " <br />";
					  
					$image = new ResizeImage();
					$image->load("" . $dirname . "/" . $_FILES["file"]["name"][$i]);
					$image->resizeToHeight(1080);
					$image->save("" . $dirname . "/" . $_FILES["file"]["name"][$i]);
					$image->resizeToHeight(38);
					$image->save("" . $dirname . "/thumb_" . $_FILES["file"]["name"][$i]);
				}
			}
		}
		else
		{
			echo "Geen geldig bestand <br />";
		}
	}
}
?>

 

Any insights would be really helpfull or maby a work-around if this doesn't work.

Is it an idea to use $_GET or sessions if nothing seems wrong?

I have tested in Chrome, FireFox 14, IE 9 and all give the same result.

 

Kind regards/Thanks in advance,

Erik

You are probably exceeding the post_max_size setting in the php.ini, which would cause $_POST and $_FILES to be empty.

What's the output of the following lines of code?

echo '<pre>';var_dump ($_POST); var_dump ($_FILES);die ();

See what your $_POST and $_FILES arrays actually contain when the form is submitted and use that information to start debugging the problem.

 

echo '$_POST array:<pre>';
print_r($_POST);
echo '</pre><br>$_FILES array:<pre>';
print_r($_FILES);
echo '</pre>';

Thanks all for the very quick responses.

I put both codes in the form action file and well, here are the results:

ChristianF code:

array
  empty
array
  empty

 

Pikachu2000 code:

$_POST array:
Array
(
)

$_FILES array:
Array
(
)

 

I tried it again after closing all the browsers and then restarting WAMP fully before trying again.

It seems to work fine for a single file but when selecting multiple it seems to fail.

Sorry scootstah, i missed your post. You seem to have very very good point there!

 

I have tested some things and indeed when choosing smaller images it results in success so the uploads have indeed exceeded the maximum size it seems.

I will have to sort that out later today since i have to go now but thanks so much for pointing me to it.
