从数组中获取数据以用于电子邮件

Question

I have the following example of a series of checkboxes on a form:

<?php

echo $this->Form->input(
    'reason', array(
        'label'=>false,
        'type' => 'select', 
        'multiple' => 'checkbox',
        'options' => array(
            'Contact me' => 'Contact me',
            'Brochure request' => 'Brochure request',
            'Demonstration request' => 'Demonstration request',
            'Training' => 'Training',
            'Support' => 'Support',
            'Other' => 'Other'
        )
    ));

?>

This is then set as a variable in the controller like:

$this->set('reason', $this->data['Contact']['reason']);

And then in the email template I have tried doing this:

<?php var_dump( implode( ', ', $reason ) ); ?>

Which gives a result like: string(28) "Contact me, Brochure request" How do I remove those quotation marks and the string(28) prefix?

What's the best way of doing this? Thanks

Answer 1

use the string helper/text helper. It has a built in toList function.

// controller
App::uses('String', 'Utility');
echo String::toList($this->request->data['Contact']['reason']);

// or
// controller
$this->set('reason', $this->data['Contact']['reason']);
// view
echo $this->Text->toList($reason);
// outputs 1, 2, 3 and 4

assuming reason is an array in the format:

array(
    (int) 0 => '1',
    (int) 1 => '2',
    (int) 2 => '3',
    (int) 3 => '4'
)

or just do a simple foreach($reason as $k => $v) { echo $v; }
