Forms and remembering values help

[focus310]

Hello:

I was hoping that someone can help me out.

I have a form which asks for three pieces of information: purchase price, planned closing date and location.

When the person hits the Submit button, they are brought to the next screen which goes through some calculations, etc.

If the results are not favorable, I would like the person to click the Back button and return to this first form and be able to make changes. When the Back button is clicked, I would like for the information which was entered to be displayed. I don't want the person to re-enter everything.

I was able to get the purchase price and location fields to work with no problem. The trouble I have is with the planned closing date. I am unable to figure out how to maintain that information.

I do have sessions turned on in a file called header.html which is included in the script. I tried a number of things and I keep getting syntax errors.

Can someone help me out with remembering the date? Thank you for the help.

This is the script.

<?php

include('header.html');

?>

<form action="calc-best-down-pmt.php" method="post">
<table class="apptable">
<tr><td class="a"><b>Purchase Price:</b></td><td class="b"><input type="text" name="purchaseprice" id="purchaseprice" class="txt" size="45" value="<?php if (isset($_SESSION['purchaseprice'])) echo $_SESSION['purchaseprice']; ?>"></td></tr>
<tr><td class="a"><b>Planned Closing Date:</b></td>
    <td class="b">
       <?php
          $months = array (1 => 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August',
                'September', 'October', 'November', 'December');

        //Make the days and years arrays

       $days = range (1,31);
       $years = range (2007, 2015);

       //Make the months pull-down menu

       echo '<select name="month">';
       foreach ($months as $key => $value) {
       echo "<option value=\"$key\">$value</option>\n";
          }
       echo '</select>';

       //Make the days pull-down menu

       echo '<select name="day">';
       for ($day = 1; $day <= 31; $day++) {
       echo "<option value=\"$day\">$day</option>\n";
        }
       echo '</select>';

      //Make the years pull down menu

      echo '<select name="year">';
      $year = 2007;
      while ($year <= 2015) {
      echo "<option value=\"$year\">$year</option>\n";
      $year++;
        }
      echo '</select>';

?>
<tr><td class="a"><b>Property Location:</b></td>
    <td class="b"><select name="location" size=1>
 <?php    

        if(isset($_SESSION['location']) && $_SESSION['location'] == 'Georgia')
       echo '<option value="Georgia" selected> Georgia&nbsp;';
       else
       echo '<option value="Georgia">Georgia&nbsp;';
?>              </select></td></tr>
<tr><td>&nbsp;</td></tr>
</table>
<input type="submit" name="btnSubmit" id="btnSubmit" value="Calculate Best Down Payment Options and Typical Closing Costs" class="btn" >
<input type="hidden" name="submitted" value="TRUE" />

</form>

Hi,

I assume by ...

I do have sessions turned on in a file called header.html which is included in the script.

... you mean you've got the line ...

<?php
session_start();
?>

... in header.html. (My files usually end in .php ... I'm going to assume that using .html works OK).

Just after including header.html, put ...

<?php
if(!isset($_SESSION['purchaseprice'])){
	$_SESSION['purchaseprice'] = '';
}
?>

... for each variable in the form. Now you can just echo the session variable directly in the form element value. E.g ...

<tr>
	<td class="a"><b>Purchase Price:</b></td>
	<td class="b"><input type="text" name="purchaseprice" id="purchaseprice" class="txt" size="45" value="<?php echo $_SESSION['purchaseprice']; ?>"></td>
</tr>

On the second page (calc-best-down-pmt.php), you'll want to store the sent variables in these session variables. So early on in the second page (can't tell where ... haven't seen the code), put ...

<?php
$_SESSION['purchaseprice'] = $_POST['purchaseprice'];
?>

(... again for each variable in the form).

P.

Hi,

Thanks for the reply. I was able to get the purchase price with no problem. The trouble I am having is with the month/day/year drop down boxes. They are using arrays and foreach statements. These are throwing me off and I don't know how to handle them.

I think you've got to at least try. You're using arrays and foreach, so you must have some understanding, no?

Have a go and come back with a specific problem.

Paul.
