how to add a simple php calculation in email

Hi,

I just created an easy form which you can see here:
http://www.hjirenno.nl/index.php?option=com_chronoforms&chronoform=kaartenbestelle24maaie
Visitors can order cards for an event (in the field "Oantal Kaarten")
In the email I just want to calculate the total price, based on the number which is entered by the user like this 7,50*Oantal Kaarten.

This is what I already tried, but it doesn't work
<?php $oantal=&form->data['oantal'] echo 7,50*$oantal;?>

Thanks in advance

Hello!
It seems to me that there is an error in your code:

<?php $oantal=&form->data['oantal'] echo 7,50*$oantal;?>

should be

<?php $oantal=$form->data['oantal'] echo 7,50*$oantal;?>

Then, are you sure that $form->data['oantal'] is a number or a numeric value, because if it is a text, this couldn't work.

Hi Flob,

Thanks for your quick reply,
I get a blank email with the adjusted code
(yes, The field "oantal" is a number.)

Any other suggestions would be welcome.

Kind Regards,
Liesbeth

Hi!
Try adding a ";" before the echo and change the "," by a ".":

<?php $oantal=$form->data['oantal']; echo 7.50*$oantal;?>

Thank you very much, it works just fine!

Do you have a hint how I can change the "." into a "," so the output will be (for example) 30,00 euro instead of 30.00 euro?

The following code permits to set the number of decimals, the decimal separator and the thousand separator : string number_format ( float $number , int $decimals = 0 , string $dec_point = '.' , string $thousands_sep = ',' )

You can use it like this:

<?php $oantal=$form->data['oantal']; echo number_format(7.50*$oantal, 2, ',', ' ');?>

to have 2 decimals after a "," and thousands separated by a " ".

If you start using php, I have found this web site no long ago (newbe myself).

Good luck
Flo
