Contact form – subject line (fill with text field)

So if im correct we have to place this code in the fucntions file

add_filter('avf_form_subject','avia_change_mail_subject', 10, 3);
function avia_change_mail_subject($subject, $new_post, $form_params) {
$subject = urldecode($new_post['avia_3_1']);
return $subject;
}

and tell what field is to be used to fill the subject field?
and by what field it is the ‘number’ of the field?

below the link to our contact form
the field ‘onderwerp’ should be the subject line. it would be nice to be able to set the field name in the code, so when the field moves we dont get a problem.
And we would like to have an extra text set before it ‘the name of the website’.

Hi Ismael,

We also want to add a piece of static text in the subject line, so the subject would look something like this: “e-mailform – onderwerp-field-content”.

Any suggestions on how to add that in your code?

Hi Ismael,

The code is not working properly it seems.
The content from the ‘avia_4_1’ field, or any other field is not placed in the subject. The text addition ‘e-mailform – ‘ is placed.
Any ideas what might cause the content from the field not being processed?

Hi Ismael,

The code above is the same:

add_filter('avf_form_subject','avia_change_mail_subject', 10, 3);
function avia_change_mail_subject($subject, $new_post, $form_params) {
$subject = 'e-mailform - ' . urldecode($new_post['4_1']);
return $subject;
}

Can you paste the modified code here please.

That worked like a charm, thanks!!!!

Hi Guys,

An additional question or maybe a bug.
I placed another contact form in the same page, this form doesn not neccessarily need to have the subject line filled in this way.
But this extra form does not seem to work when we test it. We hit the send button and the form closes, but the thatnk you message is not displayer, nor do we receive the email.

Any ideas what might be causing this?

Love to hear from you.

Hi Ismael, what do you mean?

we have 2 form ons the page, both work and sent email.

– The first form has the subject field automatically populated with the code you supplied.
– The second form we need to function in the default way. Or also be able to have the subject line automatically populated with the content of a specific field.

Any suggestions how to ahieve this?

Hi Ismael,
Thanks for your help.

yigit is helping out on another thread about this:

Hopefully he can figure out how to get this to work.
thanks
