Phalcon - multiple checkboxes in forms - php

Question

Basically, I need to serialize multiple checkboxes before saving them in database and unserialize before displaying the form.
<input type="checkbox" name="list[option1]" value="1">
<input type="checkbox" name="list[option2]" value="1">
<input type="checkbox" name="list[option3]" value="1">
Could someone point me to the right direction please?
I've tried the following code to generate the checkboxes, but it's not working after the request.
Selected options are not getting populated to the form (other fields are fine)
<?php
$form->bind($_POST, $entity);
....
foreach ($list as $key => $option) {
$form->add(new Check("list[$key]", array('value' => 1)));
}
I suppose the same issue exists with using multi-choice select boxes.

Answer 1

I think you've got a typo. Try:
<?php
$form->bind($_POST, $entity);
....
foreach ($list as $key => $option) {
$form->add(new Check($list[$key], array('value' => 1)));
}
On a side note, the Phalcon\Tag helper can be used to generate HTML.
<?php
echo Phalcon\Tag::checkField(array($list[$key], "value" => "1"));

Answer 2

You can using my code Fdola.com.
Use
<?php
$list_module = new \App\Vendor\Fdola\Forms\CheckBoxList('list_module', ['a' => 'A', 'b' => 'B'], ['a'], ['class' => 'checkBoxList']);
$list_module->setLabel('Module hiển thị banner:');
$list_module->addValidators([
new \Phalcon\Validation\Validator\PresenceOf([
'message' => '<b>:field</b> không được phép rỗng'
])
]);
$this->add($list_module);
<?php

namespace App\Vendor\Fdola\Forms;
use Phalcon\Http\Request;
use Phalcon\Tag;
class CheckBoxList extends \Phalcon\Forms\Element {
private $_data;
private $_dataOld;
public function __construct($name, $data, $dataOld = null, $attribute = null) {
$this->_data = $data;
$this->_dataOld = $dataOld;
parent::__construct($name, $attribute);
}
public function render($attribute = null) {
$get_value = $this->getValue();
if ($get_value) {
$data = $get_value;
} else {
$data = $this->_dataOld;
}
$tag = new Tag();
$string = '';
if ($this->_data) {
foreach ($this->_data as $key => $value) {
$arr = ['id' => $this->_name . '-' . $key, 'name' => $this->_name . '[]', 'value' => $key];
if ($data && in_array($key, $data)) {
$arr['checked'] = 'checked';
}
$string .= '<label>' . $tag::checkField($arr) . ' ' . $value . '</label>';
}
}
if (isset($this->_attributes['class'])) return '<div class="' . $this->_attributes['class'] . '">' . $string . '</div>';
return $string;
}
}
