session help

[fazzfarrell]

I have create these sessions, exacly the same way on one page

<?php
session_start();
$postConn = $HTTP_POST_VARS['DelCon'];

$_SESSION["postConn"] = $postConn;
?>
<?php
session_start();
$curNcy = $HTTP_POST_VARS['curEncy'];

$_SESSION["curNcy"] = $curNcy;
?>

The $postconn works fine, but the $curNcy does not bring back the desired result?

any one help

[dymon]

$curNcy = $HTTP_POST_VARS['[b]curEncy[/b]'];

maybe the var curEncy should be curNcy. Or check what does the $HTTP_POST_VARS['curEncy'] return.

[fazzfarrell]

If i put it in like this:
<?php
session_start();
$postConn = $HTTP_POST_VARS['DelCon'];

$_SESSION["postConn"] = $postConn;
?>
<?php
session_start();
$curNcy = "British Pounds";

$_SESSION["curNcy"] = $curNcy;
?>

it returns 'British Pounds'

But I need it to come from a drop down called 'curEncy' to get the value

[dymon]

Show the code of the form from where you send the variable curEncy, with the drop down component.

Why not just use: [code]<?php
session_start();
$_SESSION["postConn"] = $_POST['DelCon'];
?>[/code] and [code]<?php
session_start();
$_SESSION["curNcy"] = $_POST['curEncy'];
?>[/code]

[fazzfarrell]

the code for the form

<form id="frmCurr" name="frmCurr" method="post">
<select name="curEncy" id="curEncy" onchange="UpdateQuantity()">
<option Selected="True"><?php echo $_SESSION['curEncy']; ?></option>
<option value="British Pounds">British Pounds</option>
<option value="American Dollars">American Dollars</option>
<option value="Euros">Euros</option>
</select>
</form>

[dymon]

[code]
<?
print $_POST['curEncy'];
?>
<form id="frmCurr" name="frmCurr" method="post" action="">
<select name="curEncy" id="curEncy" onchange="UpdateQuantity()">
<option Selected="True"><?php echo $_SESSION['curEncy']; ?></option>
<option value="British Pounds">British Pounds</option>
<option value="American Dollars">American Dollars</option>
<option value="Euros">Euros</option>
</select>
<input type="submit" value="Submit"/>
</form>
[/code]

For me this code worked.

[fazzfarrell]

thanks

only problem is they dont want a submit button!

[dymon]

ok than, show the JavaScript code, where the form is submited. Because the form and the POST variables are OK.

Why your form doesn't have an action="" atributte?

[fazzfarrell]

i think its this

<script Language="VBScript">
Sub UpdateQuantity()

frmBasket.submit

End Sub

Sub DisplayAlert()
Alert("Not currently available in electronic format")
End Sub

</script>

I have re-created these sessions

<?php
session_start();
$postConn = $HTTP_POST_VARS['DelCon'];
$_SESSION["postConn"] = $postConn;

$curNcy = $HTTP_POST_VARS['curEncy'];
$_SESSION["curNcy"] = $curNcy;
?>


that now get there values from:

<form id="frmCurr" name="frmCurr" method="post">
                    <select name="curEncy" id="curEncy" onChange="document.frmCurr.submit();">
                      <option Selected="True"><?php echo $_SESSION['curNcy']; ?></option>
                      <option value="British Pounds">British Pounds</option>
  <option value="American Dollars">American Dollars</option>
  <option value="Euros">Euros</option>
                      </select>
                                                      </form>                  </td>
                </tr>
                <tr>
                  <td align="left" valign="middle" class="FormIntroText">Country </td>
                  <td align="left" valign="middle" class="FormIntroText"><form id="frmBasket" name="frmBasket" method="post">
                    <select name="DelCon" id="DelCon" onChange="document.frmBasket.submit();">
                      <option Selected="True"><?php echo $_SESSION['postConn']; ?></option>
                      <option value="UK">UK</option>
  <option value="AGUILLA">AGUILLA</option>
  <option value="ALBANIA">ALBANIA</option>

But the problem is that when you make a seletion from one of the menus it works, change the next option that works but deletes the other sesson?

[dymon]

You have to make a check if the variable that comes from the forms are not empty, and if these are not than to create the session vars, try this:

[code]
<?
session_start();
$postConn = $HTTP_POST_VARS['DelCon'];
if ($postConn != '')
$_SESSION["postConn"] = $postConn;

$curNcy = $HTTP_POST_VARS['curEncy'];
if ($curNcy != '')
$_SESSION["curNcy"] = $curNcy;
?>
[/code]
