I have a table of information displayed on a page. Each row of this table has its own submit button. I need to be able to pass information depending on what submit button is pressed.

The form is built like

function numberSubmit_form ($form, &$from_submit){
    $form['submit'] = array(
        '#type' => 'submit',
        '#value' => t('Submit'),
    );
    return $form;
}

The rows of the table are built like:

$unvalRows[] = array(
            array('data' => '0'.substr($a[0], 2)),
            array('data' => drupal_render(drupal_get_form('numberSubmit_form'))),
        );

How am I able to determine which submit button has been used and pass the applicable phone number?

Add the phone number as an argument to numberSubmit_form and include it in your form array:

$unvalRows[] = array(
    array('data' => '0'.substr($a[0], 2)),
    array('data' => drupal_render(drupal_get_form('numberSubmit_form', $phone_number))),
);

Then in the form constructor:

function numberSubmit_form ($form, &$from_submit, $phone_number){
    $form['phone_number'] = array(
        '#type' => 'hidden',
        '#value' => $phone_number,
    );
    $form['submit'] = array(
        '#type' => 'submit',
        '#value' => t('Submit'),
    );
    return $form;
}

It will then be available to you in the submit handler:

function numberSubmit_form_submit(&$form, &$form_state) {
    // do something with $form_state['values']['phone_number']
}
  • You are right, @dooffas's approach was wrong, as he wanted to get the submit button's data... But I think using radio buttons in a form would be even easier. – Sk8erPeter Apr 17 '12 at 16:57
  • It is working fine. But i want to use '#ajax' instead of normal form submit. IF i have tried '#ajax', but it is not working. – Guru Jul 28 '15 at 4:40

Same answer as charlie except that #value didn't work for me; I had to put #default_value in the hidden field as follow:

$unvalRows[] = array(
    array('data' => '0'.substr($a[0], 2)),
    array('data' => drupal_render(drupal_get_form('numberSubmit_form', $phone_number))),
);


function numberSubmit_form ($form, &$from_submit, $phone_number){
    $form['phone_number'] = array(
        '#type' => 'hidden',
        '#default_value' => $phone_number,
    );
    $form['submit'] = array(
        '#type' => 'submit',
        '#value' => t('Submit'),
    );
    return $form;
}

function numberSubmit_form_submit(&$form, &$form_state) {
    // do something with $form_state['values']['phone_number']
}
