PHP Data saves from IE but not from Mozilla

[lau]

Ok I have an online survey with 4/5 pages. PHP code saves the data to a text file. In IE this works fine but in Mozilla Firefox no data is saved from the first page, however, all the data is saved from the subsequent pages.

 

Does anyone know why this might be?

this is the php code from the page where nothing is saved, it is the same for all the pages:

 

<?php

 

foreach ($_POST as $key => $val) {

echo '<input type="hidden" name="' . $key . '" value="' . $val . '" />' . "\r\n";

 

}

?>

sorry the code that actually saves the data is on the last page it is:

 

<?php
   $File = "Results.txt";
$Handle = fopen($File, 'a');
   foreach ($_POST as $key => $val) {
   //fwrite ($Handle, $val);
fwrite ( $Handle, $val. "," );

}
fclose($Handle);
  ?>

view the source (view -> page source) on each page and see if the hidden fields are being populated with the necessary information.

Can you post the code that creates the forms?

 

Also, I think, it would be much cleaner to save the information in a SESSION.

 

At the top of each processing script, put:

<?php
session_start();
?>

 

The instead of the code that generates the hidden input fields, do:

<?php
foreach ($_POST as $key => $val)
   if ($key != 'submit') // or whatever your submit button is named
      $_SESSION['hidden'][$key] = $val;
?>

 

In the last script where you save the information:

<?php
foreach ($_POST as $key => $val)
   if ($key != 'submit') // or whatever your submit button is named
      $_SESSION['hidden'][$key] = $val;
$File = "Results.txt";
$Handle = fopen($File, 'a');
fwrite($Handle, implode(',',$_SESSION['hidden'] . "\r\n"); //this way you don't have a trailing comma after all the values
fclose($Handle);
?>

If HTML works in one browser and not another, it is likely that the HTML markup is invalid and one browser ignores the invalid HTML while the other browser does not.

 

Copy and paste the "view source" of your form.
