Hi,
I have created a form and on submission I have used php to generate a random number which will be used as a booking reference.
The php code resides in the "On Submit code - before sending email:" section and reads as follows:
<?php
$booking = mt_rand() . "\n";
echo $booking;
?>

On submitting the form my random number is successfully generated and appears within a new content window.

However how do I echo the random number or $booking variable into my email template? or alternatively into the email subject?
I have tried
{$booking} however this doesn't work.

I appreciate any help.
Thanks

Hi seabass,

Add it to the $_POST array

JRequest::setVar('booking', $booking);

Then you can get it back later using

$booking = JRequest::getInt('booking', '', 'post');
echo $booking;

Hi Bob,
Thanks for your quick reply.
My on submit code now reads

<?php
$booking = mt_rand() . "\n";

$_POST=array (JRequest::setVar('booking', $booking);
$booking = JRequest::getInt('booking', '', 'post');
echo $booking;
?>

I have then tried to call the value using {booking} in the email template.
However I get the error:
Parse error: syntax error, unexpected ';', expecting ')' in /home/korrie/public_html/components/com_chronocontact/chronocontact.php(371) : eval()'d code on line 4

I appreciate your help.

Hi seabass,

The error is becasue you missed a ) in this line

$_POST=array (JRequest::setVar('booking', $booking);

but in fact the line is wrong so please delete it.

Becasue of the way ChronoForms works* you can't define a variable in the OnSubmit before code and them use it in the template with the {booking} syntax. Instead use <?php echo $booking; ?> in the template.

Bob

* the value substitution is done before the OnSubmit code is executed so ChronoForms doesn't know what the value is :-(

Hi Bob
I actually solved it in the meantime using this in my form:
</label><input name="booking" type="hidden" value="<?php $booking = mt_rand() . "\n"; print $booking;?>" />

I can see you had a similar workaround!

Then outputting {booking} in the email template

Next question!
Is there any way I can put the {booking} ref in the email subject, I tried a dynamic subject with "booking" but it seems to stop the form from sending.

Sorry ignore my last post.
I missed the enabled: yes button.
silly me.

Thanks for your help Bob
Really great forum and support.

Hi seabass,

A dynamic subject with just booking (no brackets, no quotes) shoudl work OK.

The problem may be the /n in the booking string as the subject can only be a single line I think. Try

<input name="booking" type="hidden" value="<?php echo mt_rand(); ?>" />

Bob
