individual attributes for each option (multi checkbox)

[rodsouto]

Hi guys, today I needed to set some data-attributes for a particular input in a multi checkbox, are you interested in this feature? :)

@rodsouto isn't it the same one you send #46 ?

[harikt]

Sorry I understood it wrongly :) . Thanks for the PR.

Travis broken due to 5.3 . Need to change short array to array.

Thanks @harikt 👍

Probably here also :) .

Done

Hey @jakejohns ,

Do you think we are good to merge this ?

[jakejohns]

I like the concept. Here's some concerns off the top of my head:

Update Docs

README-FORMS.md needs updating. In fact, I don't think the "multiple" function is even documented there, unless i'm missing it.

Should this apply to other helpers?

I wonder if similar function should be applied to Radio and Select options. I think Radio might be as easy as moving the prep of this to AbstractChecked and doing a similar thing to the multiple method. I think Select might be more difficult, and could wait if so

Spec Structure

I actually think the way it's being done here is probably the right option, but I just thought I'd throw this out there to explicitly rule it out for a valid reason. I haven't messed with the Checked helpers too much, so I very well may be missing something here.

I sort of wish the attrs weren't separate from the other content, requiring the keys to match in different arrays. But It's probably not a good idea to mess with the spec structure too much, right? eg. this is worse, or wouldn't work, right? Maybe not?:

<?php

// calling
$actual = $checkbox(array(
    'name' => 'foo',
    'value' => 'yes',
    'options' => array(
        'yes' => array(
            'label' => 'Yes',
            'attr' => array('class' => 'test-class')
        ),
        'no' => array(
            'label' => 'No',
            'attr' => array('data-no' => 1)
        ),
    )
));


// Checkbox.php ... totally untested
protected function multiple()
{
    $html = '';
    $checkbox = clone($this);

    $this->attribs['name'] .= '[]';

    foreach ($this->options as $value => $label) {

        $attr = array();

        if (is_array($label)) {
            $attr = $label['attr'];
            $label = $label['label'];
        }

        $this->attribs['value'] = $value;
        $this->attribs['label'] = $label;

        $html .= $checkbox(array(
            'name'    => $this->attribs['name'],
            'value'   => $this->value,
            'attribs' => $this->attribs + $attr
        ));
    }
    return $html;
}
