Session &amp; HTML Form Problem

Session & HTML Form Problem

jkatcher

Hi all --

I'm trying to do the basic data entry into an HTML forum, run a check, and if incorrect, go back to the original page, with all values that were entered, remembered. I'm trying to use sessions to do this, but am having some trouble.

Page1:


<?php
//START SESSION
session_start();
?>

<html>
<center>
<table width="700" border="0" cellspacing="0" cellpadding="0" height=500>
<tr>
<td valign=top height=450 width="200">
<img src="images/sp.gif">
</td>
<td valign="top" height="450" width="500">
<!--TEXT GOES HERE-->

<form method="post" form action="newUserSubmit.php">
Email:<br>
<input type="text" name="email" value=<? $_SESSION['email']; ?>><br><br>

First Name:<br>
<input type="text" name="fname"><br><br>

Last Name:<br>
<input type="text" name="lname"><br><br>

Phone:<br>
<input type="text" size="3" name="phone1">
&nbsp;<input type="text" size="3" name="phone2">
&nbsp;<input type="text" size="4" name="phone3"><br><br>

Desired User Name:<br>
<input type="text" name="user"><br><br>

Password:<br>
<input type="password" name="pass"><br><br>

Re-type Password:<br>
<input type="password" name="passVerify"><br><br>

<input type="submit" value="Sign up" class="button">
<input type="reset" value="Clear" class="button">
</form>


</td>
</tr>						
</table>
</center>

Currently, only the email field has the $_SESSION['email'] argument in it, just testing. However, none of the input gets transferred back on the redirect.

Page1 gets submitted to Page2 below:


<?php

//START SESSION
session_start();

include 'misc.inc';
include 'connect.php';
include 'functions.php';

//GLOBAL VARIABLES
$fname = $_POST[fname];
$lname = $_POST[lname];
$phone = $_POST[phone1]  .  "-"  .  $_POST[phone2]  .  "-"  .  $_POST[phone3]; // phone1 area code phone 2 prefix phone 3 last four
// posting phones separately so each can be assigned a separate session variable
$phone1 = $_POST[phone1];
$phone2 = $_POST[phone2];
$phone3 = $_POST[phone3];
$email = $_POST[email];
$passSlash1 = $_POST[pass];
$passSlash2 = $_POST[passVerify];
$pass = stripslashes($passSlash1); //this strips the slashes so it is nicely formatted for the email
$passVerify = stripslashes($passSlash2); //this strips the slashes so it is nicely formatted for the email
$userSlash = $_POST[user];
$user = stripslashes($userSlash);

//SESSION VARIABLES, where variable in brackets is a NEW assigned session name
$_SESSION['fname'] = $fname;
$_SESSION['lname'] = $lname;
$_SESSION['phone1'] = $phone1;
$_SESSION['phone2'] = $phone2;
$_SESSION['phone3'] = $phone3;
$_SESSION['email'] = $email;
$_SESSION['user'] = $user;

// pass variables $pass and $passVerify to function, to function properly
verifyPassword($fname, $lname, $phone1, $phone2, $phone3, $email, $user, $pass, $passVerify);

?>

In the above page, a the function verifyPassword() is called, below is the page where it is defined:


<?php
session_start();

// pass the arguments $pass and $passVerify to the function
function verifyPassword ($fname, $lname, $phone1, $phone2, $phone3, $email, $user, $pass, $passVerify)
{
   if ($pass != $passVerify)
      {
        header("Location: newUser.php");
      }
}
?>

Any ideas why the value the user inputted in the email field is not getting passed back after the redirect? Thanks very much for any input!

Here is a short example of an easy way I do this.... Just change you varibles to whatever they really are :-)

<?php
session_start();
include_once 'check_status.inc';
include_once 'header.inc';
$username = $_SESSION['username'];
$word = $_POST['word'];
$define = $_POST['define'];
$uses = $_POST['uses'];
?>

Then a little later in the form itself...

<?php
                  echo "<input type='hidden' name='username' value='$username' size='20' id='username'>";
                  ?>

                Word or Phrase:
                                                  <?php
                echo "<input type='text' name='word' size='43' value='$word'></td>";
                                                   ?>

If you have not posted anything yet the value will show up as empty, however if you have posted and after error checking, you are kicked back the form text fields will be filled in with your previously posted information.

Hope this helps

As far as error checking and kicking it back if something isn't the way you want it... I use the following:

if((!$username) || (!$word) || (!$define)){

echo '<center><b><font face="tahoma" color="red">You did not enter some required information before submitting the form! </b><br />';


if(!$username){
  Echo "There was an error logging your current username.<br />";
}
if(!$word){
  Echo "Word is a required field.<br />";
}
if(!$define){
  Echo "Define is a required field.<br />";
}

//re-include the form so the errors can be fixed

include 'add_define_form.php';

  exit();

}

//check that new word does not already exist


$sql_word_check = mysql_query("SELECT word FROM define
                         WHERE word='$word'");

$word_check = mysql_num_rows($sql_word_check);

if(($word_check > 0)){
  echo "<center><b><font face='tahoma' color='red'>Please fix the following errors: </b><br />";
  if($word_check > 0){
    echo "The word you have submitted has already been defined in our database.
    Please submit a different word or phrase!<br />";

 unset($word);
   }


   include 'add_define_form.php';
   exit();
}

// Or go to the add / update info in database if everything is right (below this)

have u put session_start() in page1 too ?

jkatcher

yes, there are session_start() commands on each page
