Placeholder in element value with javascript

[paveo]

Hi,
I have a radiobutton which set the value of a 2nd element depending on the radiobutton value. It works fine but I'm trying to add a placeholder of a 3rd element in the 2nd element value with javascript code but it doesn't work.
My code is :

if(this.getValue() == 'value_of_radiobutton'){
$('table_name___2nd_element_name').value = "message :{table_name___3rd_element_name}"
}
Can you help me?
Thanks

Placeholders aren't available in Javascript.

The best approach is to use the main element object structure for the form. Replace X in form_X with your numeric form ID in this:

if(this.getValue() == 'value_of_radiobutton'){
   var form = Fabrik.getBlock('form_X');
   var el2 = form.formElements.get('table_name___2nd_element_name');
   var el3 = form.formElements.get('table_name___3rd_element_name');
   el2.update("message : " + el3.getValue());
}

Thanks Hugh,

It works great. Now I want to add the element id after el3 but it doesn't show. Why?

if(this.getValue() == 'value_of_radiobutton'){
  var form = Fabrik.getBlock('form_X');
  var el2 = form.formElements.get('table_name___2nd_element_name');
  var el3 = form.formElements.get('table_name___3rd_element_name');
  var el4 = form.formElements.get('table_name___element_id');
  el2.update("message : " + el3.getValue() + el4.getValue());
}

What do you mean by "the element id"? You mean the 'id' element for the row, i.e. the primary key value for the table?

Is this a new form, or editing an existing one?

If it's a new form, 'id' won't have a value yet, as the 'id' isn't assigned until the form is submitted.

And if you do literally mean the 'id', then it would probably be called table_name___id, not table_name___element_id?

Yes it's table_name___id, sorry.
I want to show the message in the notification e-mail. So, as the table_name___id won't have value until the form is submitted, can I write php code in my php email template which will get and display these element values?

 

[cheesegrits]

Yes.

When running a PHP template, all the form's data is in $emailData, keyed by full element name.

Easiest thing to do is start by doing this:

var_dump($emailData);exit;

... and run a form submission. This should dump out the $emailData structure and content. Keep that tab, open another one, and work in that, remove the var_dump(), and code your template, referring to the dump of $emailData for what you need. Which might be ...

if ($emailData['tablename___radiobutton'] == 'yes') {
   echo "message: " . $emailData['tablename___el1']  . $emailData['tablename___el2'] .  $emailData['tablename___id'] . "<br />\n";
}

... or whatever.

It's exactly what I needed. Thanks a lot.
I've just added [0] after ['tablename___radiobutton_raw'] because var_dump($emailData);exit; returned ["tablename___radiobutton_raw"]=> array(1) { [0]=> string(3) "yes" }
so my code is :

if ($emailData['tablename___radiobutton'] [0] == 'yes') {
  echo "message: " . $emailData['tablename___el1']  . $emailData['tablename___el2'] .  $emailData['tablename___id'] . "<br />\n";
}

Looks right. Glad it worked for you.

There are better ways to code that sort of thing, using more "defensive" coding, using either PHP functions or J! helper functions to make sure array keys exist, etc. and avoid tossing PHP warnings if the expected data isn't there ... but that'll work as-is.
