php upload doesnt POST any info in Firefox

arianhojat · May 23, 2007

Hello all,

I am not sure why but I have had this problem for a while and havent really been able to solve it.

A really simple php upload script works in IE but not in FF. FF just comes back to the page as if there is no POST information.

For example code below will output when landing on the page, it outputs:

count:0

NOT SUBMITTED, 5-23-2007 16:13:35

and when trying to post the upload via the html submit button, it outputs immediately:

count:0

NOT SUBMITTED, 5-23-2007 16:13:54

but it SHOULD have POST data?, count should be > 0, and it should output SUBMITTED

if enctype="multipart/form-data" is removed, it will post the data (of course no upload data though):

count:3

data=Array ( [filename] => Array ( [0] => blc.gif [1] => ) [MAX_FILE_SIZE] => 100000000 [submitForm] => Submit )

SUBMITTING

<?php

echo 'count:'. count($_POST) .'<br/>';

if( count($_POST) > 0 )
{ 
echo 'data='; 
print_r($_POST); 
}

if( isset($_POST['submitForm']) )
{
echo "SUBMITTING<br/>" ;

foreach ($_FILES["filename"]["error"] as $key => $error) 
{
	if ($error == UPLOAD_ERR_OK) 
	{
		$path_parts = pathinfo(__file__);
		$dir = $path_parts['dirname']."\\uploads";


		$tmp_name = $_FILES["filename"]["tmp_name"][$key];
		$name = $_FILES["filename"]["name"][$key];
		move_uploaded_file($tmp_name, "$dir\\$name");
		echo "tmp_name=$tmp_name, name=$name, type=$type, size=$size<br/>" ;
	}
	else
	echo 'error:'.$error;
}	


}//submitted
else
echo "NOT SUBMITTED, ". date('n-j-Y G:i:s') .'<br/>';

<body>

<form name="upload" method="post" enctype="multipart/form-data" action="<?php echo $_SERVER['PHP_SELF'];?>">

File to upload: <br/>
<input type="file" name="filename[]" value="Upload1" />
<br/>
<input type="file" name="filename[]" value="Upload2" />
<br/>

<input type="submit" name="submitForm" value="Submit" />

</form>
</body>
</html>

When i had this problem, I always thought maybe it was the type of data, like images, word docs, pdfs, specifically in FF. but it looks like i cant upload even text files with this simple script. Anyone got ideas?

The only thing in the $_POST array will be the submit button. The file data will be in the $_FILES array.

Hey barand,

when posting, $_POST still has 0 things in it. So it should at least have the submit button like you said, and MAX_FILE_SIZE hidden var.

I trimmed the code down and works OK

<?php
if (isset($_POST['submitForm']))
{
    echo '<pre> POST ', print_r($_POST, true), '</pre>';
    echo '<pre> FILES ', print_r($_FILES, true), '</pre>';
}
?> 
<form name="upload" method="post" enctype="multipart/form-data" action="<?php echo $_SERVER['PHP_SELF'];?>">

File to upload: <br/>
<input type="file" name="filename[]" value="Upload1" />
<br/>
<input type="file" name="filename[]" value="Upload2" />
<br/>

<input type="submit" name="submitForm" value="Submit" />

</form>

hey barand,

Still doesnt work for me.

Maybe its an IIS/php issue.

I use IIS and php and this works fine for me. Looks just like yours really, maybe it is that you are using "filename". But here is my working code.

<?php
$absolute_path = "C:/Inetpub/wwwroot/phpforum/images"; //Absolute path to where files are uploaded
$size_limit = "yes"; //do you want a size limit yes or no.
$limit_size = "600000"; //How big do you want size limit to be in bytes
$limit_ext = "yes"; //do you want to limit the extensions of files uploaded
$ext_count = "3"; //total number of extensions in array below
$extensions = array(".jpg", ".png", ".gif"); //List extensions you want files uploaded to be

if(!isset($_POST['submit'])){
$extens = '';

        if (($extensions == "") or ($extensions == " ") or ($ext_count == "0") or ($ext_count == "") or ($limit_ext != "yes") or ($limit_ext == "")) {
           $extens = "any extension";
        } else {
        $ext_count2 = $ext_count+1;
        for($counter=0; $counter<$ext_count; $counter++) {
            $extens .= "  $extensions[$counter]";
        }
        }
        if (($limit_size == "") or ($size_limit != "yes")) {
            $limit_size = "any size";
        } else {
            $limit_size .= " bytes";
            $mb_size = ($limit_size/1000000);
        }
        $pichead = "<li><font size=\"2\" color=660000>File extension must be $extens<b>";
        $pichead .="</b></font>
        <li><font size=\"2\" color=660000>Maximum file size is $limit_size ($mb_size MB)</font></li>
        <li><font size=\"2\" color=660000>No spaces in the filename</font></li>";
?>

  $file =  $_FILES["pictures"]['tmp_name'][$i];
  $file_size = $_FILES["pictures"]['size'][$i];
  $endresult = "<font size=\"4\" color=990000>$file_name uploaded successfully</font>";
    if ($file_name == "") {
    $pic = $i+1;
    $endresult = "<font size=\"4\" color=990000>Pic#$pic Not selected</font>";
