Custom action on form submit

Hi, I am a newbie to Contao CMS. I have a form, which saves data to a database. In the form, there is also an input for an e-mail adress. I need to save submited data to the database and also add the e-mail address to a newsletter table.
I think that one possible way how to do this stuff is add a condition, based on my form ID, to a Contao script, which submits the forms.
But where can I find a file with this script? Or is there any other way how to solve this task?
Thank you very much!!

You can do it with the "processFormData" hook

Hmm, so I can create my own PHP class and then define a hook for the function of this class in the localconfig.php file.
Can someone tell me what I have to do next please?
Sure, I can use my own script, for example - mysql_query("insert into newsletter_table...")) - but this way is probably bad.

Which version of Contao are you using?

Did you take a look at the efg extension?

https://contao.org/en/extension-list/view/efg.en.html

The efg extension can save the form data into a custom table but for the newsletter subscription part you need to create your own hook

The best way to code something for Contao is using its API

I need to set up this feature for Contao 2.11.
Yes, I have the EFG extension installed, but it hasn't the functionality that I need.
Unfortunately I don't understand the API very well. :(
Can you write me a snippet of code or some example for this, please?

I just wrote a quick tutorial

hope it helps you to get started

Ok, and now I can call the addRecipient function?

if the field which contains the email address is named email you can do this in the hook method:

Code:

---


$arrData = array(
'pid' => 1, // this is your newsletter ID
'tstamp' => time(),
'email' => $arrPost['email'],
'active' => '1',
'addedOn' => time()
);

$res = $this->Database->prepare('INSERT INTO tl_newsletter_recipients %s')->set($arrData)->execute();

---

Thanks, but when I use this code, I get a blank white page on form submit.
If I comment the "$res = ...." line, the form is submitted successfully.

put this before the $res ...

Code:

---

$this->import('Database');

---

you've got a blank screen because you set the option to not display errors next time check the system/logs/error.log file ;)

You are the man! Thank you very much!
