underfined variable? session?

[bilis_money]

hi guys

 

i have two pages they are both .php,

step1.php has form on it that will pass the value on step2.php

 

but it give me an error below,

Notice: Undefined variable: squareyard in /home/travels/public_html/walkie/step2.php on line 19

 

here is step1.php

<?php
session_start();
?>

<br><br>
<center>
<h1>Step 1. Results</h1>
<br>
<div align='center'>
  <table width='60%'  border='0'>
    <tr>
      <td bgcolor='#99FFFF'><strong>Converting Sand to gallons: </strong></td>
    </tr>
  </table>
</div>	


<?php
//"First Name:  " . $_POST['fname'] .    			

//initialize variables
$coaltar = 100;
$water = $_POST['water'];
$sand = $_POST['sand'];
$additive = $_POST['additive'];

echo "<br>";
echo "<center>";
echo "<strong>";
echo "sand x 100 (CT) = x divided by 20 = x gallons of sand";
echo "</strong>";
echo "</center>";

$sandtogallon = $sand * 100 / 20;

//100 + 30 + 15 (sand in gallons) + 2 (gal of additive) = 147 
$maingallonformula = 100+$water+$sandtogallon+$additive;
$totalgallonsmaterial = 100/$maingallonformula;

echo "<br>";
?>
<div align='center'>

		echo "<br>";			
		echo "Total gallons of materials: " . $totalgallonsmaterial;
		echo "</strong>";

//storing it into session
$_SESSION['totalgallonsmaterial2'] = $totalgallonsmaterial;

?>
	    </tr>
	</td>
  </table>
</div>	

<br>
<div align='center'>
  <table width='60%'  border='0'>
    <tr>
      <td bgcolor='#99FFFF'><strong>Total gallons needed: </strong></td>
    </tr>
  </table>
</div>	

<?php
echo "<br>";
echo "<center>";
echo "<strong>";
echo "Sq. Yards (divided by) 5 = Total gallons needed";
echo "</strong>";
echo "</center>";



?>

<div align="center">
  <form name="form1" method="post" action="step2.php">
    <table width="20%"  border="1">
      <tr>
        <td width="81%"><div align="center"><strong> Sq. Yards </strong></div></td>
        <td width="19%"><div align="center"></div></td>
      </tr>
      <tr>
        <td><div align="center">
          <input type="text" name="squareyard">
        </div></td>
        <td><div align="center"><strong>/ 5</strong></div></td>
      </tr>
    </table>
    <p>
      <input type="submit" name="Submit" value="calculate">
    </p>
  </form>
</div>

 

here is step2.php

<?php
session_start();
//$_SESSION['totalgallonsmaterial2'] = $totalgallonsmaterial;
//echo $_SESSION['totalgallonsmaterial2'];
?>

<br><br>
<center>
<h1>Step 2. Results</h1>
<br>
<?php


echo $_SESSION['totalgallonsmaterial2'];

//Sq. Yards (divided by) 5 = Total gallons needed
$gallonsofmaterial2 = $squareyard * 5;

echo "<strong>";
echo $gallonsofmaterial2 . " gallons of material needed";
echo "</strong>";

?>

 

 

I'm wondering if the session_start() affected this?

any nice guess?

 

thanks in advance.

Try the pages below

 

step1:

<?php
session_start();
//$_SESSION['totalgallonsmaterial2'] = $totalgallonsmaterial;
//echo $_SESSION['totalgallonsmaterial2'];
?>

<br><br>
<center>
<h1>Step 2. Results</h1>
<br>
<?php


echo $_SESSION['totalgallonsmaterialtwo'];

//Sq. Yards (divided by) 5 = Total gallons needed
$gallonsofmaterial2 = ($squareyard * 5);

echo "<strong>";
echo $gallonsofmaterial2 . " gallons of material needed";
echo "</strong>";

?>

 

step2.php

<?php
session_start();
?>
