I have added two fields in to my custom content type using "Add existing field".
For specific URL, I need to set these two fields as Required.
So I have altered my form and set required condition. After setting it, I have printed the form using devel, these fields are having required settings.
$form['field_name']['und']['#required'] = TRUE;
$form['field_email']['und']['#required'] = 1;
dsm($form);
But required condition is not applied.
That is, I could not see red color required indication as well as its not working in the form submit.
