Zend_Form : data table with checkboxes - zend-framework

Question

I'd like to have a table of data coming from the DB in my form element, looking like the following :
+-----+-------------------------+-----------------------+
| | Number | Name |
+-----+-------------------------+-----------------------+
| [ ] | 123 | ABC |
+-----+-------------------------+-----------------------+
| [x] | 456 | DEF |
+-----+-------------------------+-----------------------+
| [x] | 789 | HIJ |
+-----+-------------------------+-----------------------+
It would allow to select several rows, like the MultiCheckBox element.
Here is the kind of markup I would like to have:
<table>
<thead>
<tr>
<th>Select</th>
<th>Number</th>
<th>Name</th>
</tr>
</thead>
<tr>
<td><input type="checkbox" name="subscribers[]" value="1234"></td>
<td>1234</td>
<td>ABC</td>
</tr>
<tr>
<td><input type="checkbox" name="subscribers[]" value="375950"></td>
<td>375950</td>
<td>DEF</td>
</tr>
<!-- and so on... -->
I can do it by hand but using Zend_Form would allow me to populate the form, retrieve the values easily and to have validation. I have other normal elements in my form.
Any idea on how to achieve this with Zend_Form ? Maybe a custom element and decorator ?
Thanks. Ask for more info if needed.

Answer 1

ok, so this is going to be a longer sort of answer
the Form
<?php
class Form_MyTest extends Zend_Form
{
public function init()
{
$element = $this->createElement('multiCheckbox', 'subscribers');
$element->setOptions(array('value1' => 'label1', 'value2' => 'label2'));
$this->addElement($element);
// ... other elements
}
}
Controller
<?php
class MyController extends Zend_Controller_Action
{
public function myTestAction()
{
$form = new Form_MyTest();
// ... processing logics
$this->view->assign('form', $form);
}
}
View
<form action="<?php echo $this->form->getAction(); ?>" method="<?php echo $this->form->getMethod(); ?>">
<table>
<thead>
<tr>
<th>Select</th>
<th>Number</th>
<th>Name</th>
</tr>
</thead>
<?php $values = $this->form->getElement('subscribers')->getValue(); ?>
<?php foreach($this->form->getElement('subscribers')->getMultiOptions() as $key => $value) : ?>
<tr>
<td><input type="checkbox" name="subscribers[]" id="subscribers-<?php echo $key; ?>" value="<?php echo $key; ?>" <?php echo in_array($key, $values) ? 'checked="checked"':''; ?>/></td>
<td><label for="subscribers-<?php echo $key; ?>"><?php echo $key; ?></label></td>
<td><label for="subscribers-<?php echo $key; ?>"><?php echo $value; ?></label></td>
</tr>
<?php endforeach; ?>
</table>
<!-- rest of form -->
</form>
A couple things are happening here.
I get the prepopulated values out of the form object:
<?php $values = $this->form->getElement('subscribers')->getValue(); ?>
I mark each checkbox as checked or not based on the array above
<?php echo in_array($key, $values) ? 'checked="checked"':''; ?>
EDIT IN RESPONSE TO COMMENT B/C COMMENTS DON'T SUPPORT PRE BLOCKS
the
$element->setOptions(
or
$element->setMultiOptions(
only accepts key => value pairs, so anything you want to do outside of key value pairs is going to be a little wierd. If your program allows you could pass another variable to the view, an array that uses the same keys as the multiCheckbox so
$this->view->assign('more_datums', array('value1' => array('col_1' => 'col_1_val'[, ...])));
and then in the foreach in the view use
$this->more_datums[$key]['col_1']
