Cakephp 3. Image Radio Buttons - cakephp

Question

Regarding to Cakephp 3 Form Helper, for Radio Buttons with Images, i got a question need to ask for help.
From the forumn there's a question, but it was 10 years version earlier, which is not suitable for my codes.
originally the Add.ctp for this item is meant for Type=>Select
<?php echo $this->Form->control('product_image_id', array('label'
=> false, 'div' => false,
'class' => 'form-control', 'type' => 'select', 'empty' =>
'Choose Image')); ?>
in the Type select, the name of the images only shows out. not the images.
When i want to put the Form Control into the code for the add.ctp
<?php foreach ($product['product_images'] as $productImg) : ?>
<div class="container parent">
<div class="row">
<div class='col text-center'>
<?php echo $this->Form->control('product_image_id', ['type' =>
'radio', 'escape' =>
false, 'class' => 'form-control', 'id' =>$productImg->id,
'name'=>'imgbackground' ]); ?
>
<label for="<?= $productImg->id ?>">
<?php
echo $this->Html->image($imgPath, ['width' => '100']);
?>
<div class="tick_container">
<div class="tick"><i class="fa fa-check"></i></div>
</div>
</label>
</div>
</div>
</div>
<?php endforeach; ?>
Information regarding settings for Form Control for radio buttons is limited....
can anyone help to advise where i went disaligned?
thanks

Answer 1

You basically have two options, that is either manipulate the radio options for FormHelper::control() to include your custom label contents, or to manually create each label and radio button.
For the former you build an options array that holds nested arrays with text and value keys, where text is the label contents, and value the radio button value, eg
[
['text' => '<img src="..."> ...', 'value' => '1'],
['text' => '<img src="..."> ...', 'value' => '2'],
// etc ...
]
A quick and dirty example could look like this (I'm just guessing here that there's something like a path property on your product images, you'll most likely have to adjust this a bit according to your needs to build the proper web path to the image):
echo $this->Form->control('product_image_id', [
'type' => 'radio',
'templates' => [
'radioWrapper' => '{{input}}{{label}}',
'nestingLabel' => '{{hidden}}<label{{attrs}}>{{text}}</label>',
],
'labelOptions' => [
'escape' => false,
],
'options' => collection($product['product_images'])
->map(function ($productImage) {
return [
'text' =>
$this->Html->image($productImage->path, ['width' => '100']) .
'<div class="tick_container">
<div class="tick"><i class="fa fa-check"></i></div>
</div>',
'value' => $productImage->id,
];
}),
]);
Note that you need to define custom/modified templates for the label and the wrapper if you actually need the input to be rendered outside of the label. If you don't actually need it to be rendered that way, then you can drop this example's templates option, by default the form helper would render the input inside of the label, eg:
<label><input/>text</label>
