I am learning hook_form_alter(). I am trying to change "Contact" form. I want to change the title "Your name" to "Full name".

I create a module that is named "mymodule", only write the below code in "mymodule.module"

function mymodule_form_alter($form, &$form_state, $form_id) {
    $form['name']['#title'] = t('Full name');

When I access "/contact", it still shows "Your name". Then I installed Devel module and change below code

function mymodule_form_alter($form, &$form_state, $form_id) {
    $form['name']['#title'] = t('Full name');
    dsm($form);
}

I access "/contact" again. The below information is shown in message block

... (Array, 24 elements)
#attributes (Array, 1 element)
name (Array, 5 elements)
#type (String, 9 characters ) textfield
#title (String, 9 characters ) Full name <---------------
#maxlength (Integer) 255
#default_value (String, 5 characters ) admin
#required (Boolean) TRUE
......

It shows the title name is changed to "Full name", but the display is still "Your name".

Do I forget to set something or use wrong command?

First parameter in your form_alter declaration must be by reference. Put &$form instead $form.

Other thing, with this hook you are changing name title in all forms that this field exist. If you want change it only in contact form use a conditional in this hook, or use a hook_form_FORM_ID_alter method

Thank you for reminding. I just test hook_form_FORM_ID_alter. It is working.

function mymodule_form_contact_site_form_alter(&$form, &$form_state, $form_id) {
  	$form['name']['#title'] = t('Full name');
}

It's nice

Hi,
I am trying to add the placeholder-attribute on the input field for my exposed filter.
I tried the following code block:

function mymodule_form_alter(&$form, &$form_state, $form_id){
echo 'Debug';
  if($form_id == "views_exposed_form"){
    debug($form); // print $form array on the top of the page
    if (isset($form['title'])) {
            $form['title'][] = array('#placeholder' => t('placeholder value'));
    }
  }
}

I couldn't get it to work, so I tried using hook_form_FORM_ID_alter method, by modifying the above code. But still no luck. It is not even able to reach the function. Can anyone tell me what I might be doing wrong?
I am implementing these codes in template.php file and want to make sure if this is the right place to make changes?

Thanks!

$form['title']['attributes']['#placeholder'] = t('placeholder value');

I am not 100% sure but shouldn't the hash be on the "attributes" property? Otherwise the Form API will assume "attributes" is a child object to be rendered, and won't have any idea what to do with the #placeholder property.

$form['title']['#attributes']['placeholder'] = t('placeholder value');

You're right, I've updated my code accordingly. Thanks.

change your function and use pass by reference

mymodule_form_alter(&$form, &$form_state, $form_id)

use the $form_id that was passed by reference to check if you are in the correct for you want to alter

inside the conditional statement

try to
dsm($form)

and check what you want to change.

Don't try to put a :

return $form;

at the end. ;)

Now the order is:

Your name *
Your e-mail address *
Subject *
Message *

If I want to add a new field between "Your email address" (mail) and "Subject" (subject). like this

Your name *
Your e-mail address *
new field <---------------
Subject *
Message *

I know change weight of "name", "mail". If one form have many fields before the "new field", should I change every field weight before it?

In this case, or if your form fields increase, you can easily set this code in your form_alter:

$order = array('your_first_field_name','your_second_field_name', .... , 'your_last_field_name' );
//set a weight for each field 
foreach ($order as $key => $field) {
    $form[$field]['#weight'] = $key;

  }

With this code you are controling weight order with $order array!

Hi ,

First check what your contact form id is by dsm($form_id)

if ($form_id == 'search_block_form') {
// here your logic will come to alter the name or title of the form
}

Note that dsm() will only work if you have the devel module enabled. If you do not have this module enabled, you can use debug().

set
package :Core
in info file

and then write in your module file
//first method
use Drupal\Core\Form\FormStateInterface;
function hook_form_FORMID_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state) {
$form['phone_number']['#title'] = t('Start with + and your country code.');

}
//Second Method--------------------------------------------
function hook_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id)
{
if($form_id == 'user_login_form')
{
$form['name'] = array(
'#type' => 'textfield',
'#title' => t('name'),
);
}

if($form_id == 'second_form')
{
$form['phone_number'] = array(
'#type' => 'tel',
'#title' => t('name'),
);
}
}
