CakePHP 2.0 Determine which submit button has been clicked

Question

In CakePHP 1.3 you can create a form with multiple submit buttons:

echo $this->Form->submit(\'Submit 1\', array(\'name\'=>\'submit\');
echo $this->Fo         


        

Answer 1

Don't use the same name for both submit buttons. Consider this example:

Form->create(false); ?>
Form->text('input'); ?>
Form->submit('Yes', array('name' => 'submit1')); ?>
Form->submit('No', array('name' => 'submit2')); ?>
Form->end(); ?>

debug($this->request->data) will produce the following when the "Yes" button is clicked:

array(
    'submit1' => 'Yes',
    'input' => 'test'
)

And here it is when the "No" button is clicked:

array(
    'submit2' => 'No',
    'input' => 'test'
)

To check which button was clicked:

if (isset($this->request->data['submit1'])) {
    // yes button was clicked
} else if (isset($this->request->data['submit2'])) {
    // no button was clicked
}
