使用cakephp 3.x设置class或div复选框窗体

Question

在CakePhp 3中，我有一个要插入复选框中的参数列表。我有这个代码

<?php
echo $this->Form->input('regions', [            
    'options'  => $regions,
    'value'    => Hash::extract($ad->toArray(), 'regions.{n}.id'),
    'class'    => 'col-xs-4',
    'type'     => 'select',
    'multiple' => 'checkbox',
    'label'    => false,
    'error'    => [
        'attributes' => ['class' => 'col-xs-12 error-message inline']
    ],        
]);   
?>   

类col-xs-4没有出现。我还插入了

'div' => 'col-xs-4'

而不是类。

如何在每个复选框元素处插入类或div？

这是由html生成的：

<div class="input select">
   <input type="hidden" name="regions" value="">
   <div class="checkbox"><label for="regions-1"><input type="checkbox" name="regions[]" value="1" id="regions-1">Abruzzo</label></div>
   <div class="checkbox"><label for="regions-2"><input type="checkbox" name="regions[]" value="2" id="regions-2">Basilicata</label></div>
   <div class="checkbox"><label for="regions-3"><input type="checkbox" name="regions[]" value="3" id="regions-3">Calabria</label></div>
   <div class="checkbox"><label for="regions-4"><input type="checkbox" name="regions[]" value="4" id="regions-4">Campania</label></div>
   <div class="checkbox"><label for="regions-5"><input type="checkbox" name="regions[]" value="5" id="regions-5">Emilia Romagna</label></div>
   <div class="checkbox"><label for="regions-6"><input type="checkbox" name="regions[]" value="6" id="regions-6">Friuli Venezia Giulia</label></div>
   <div class="checkbox"><label for="regions-7"><input type="checkbox" name="regions[]" value="7" id="regions-7">Lazio</label></div>
   <div class="checkbox"><label for="regions-8"><input type="checkbox" name="regions[]" value="8" id="regions-8">Liguria</label></div>
   <div class="checkbox"><label for="regions-9"><input type="checkbox" name="regions[]" value="9" id="regions-9">Lombardia</label></div>
   <div class="checkbox"><label for="regions-10"><input type="checkbox" name="regions[]" value="10" id="regions-10">Marche</label></div>
   <div class="checkbox"><label for="regions-11"><input type="checkbox" name="regions[]" value="11" id="regions-11">Molise</label></div>
   <div class="checkbox"><label for="regions-12"><input type="checkbox" name="regions[]" value="12" id="regions-12">Piemonte</label></div>
   <div class="checkbox"><label for="regions-13"><input type="checkbox" name="regions[]" value="13" id="regions-13">Puglia</label></div>
   <div class="checkbox"><label for="regions-14"><input type="checkbox" name="regions[]" value="14" id="regions-14">Sardegna</label></div>
   <div class="checkbox"><label for="regions-15" class="selected"><input type="checkbox" name="regions[]" value="15" checked="checked" id="regions-15">Sicilia</label></div>
   <div class="checkbox"><label for="regions-16"><input type="checkbox" name="regions[]" value="16" id="regions-16">Toscana</label></div>
   <div class="checkbox"><label for="regions-17"><input type="checkbox" name="regions[]" value="17" id="regions-17">Trentino Alto Adige</label></div>
   <div class="checkbox"><label for="regions-18"><input type="checkbox" name="regions[]" value="18" id="regions-18">Umbria</label></div>
   <div class="checkbox"><label for="regions-19"><input type="checkbox" name="regions[]" value="19" id="regions-19">Valle d&#039;Aosta</label></div>
   <div class="checkbox"><label for="regions-20"><input type="checkbox" name="regions[]" value="20" id="regions-20">Veneto</label></div>
</div>

最后，我解决了以下问题：

<?php
echo $this->Form->input('Regions',               
    [   
    'templates' => [ 
        'checkboxWrapper' => '<div class="col-xs-4 checkbox">{{label}}</div>',
    ],
    'options'  => $regions,
    'value' => Hash::extract($ad->toArray(), 'regions.{n}.id'),
    'type'     => 'select',
    'multiple' => 'checkbox',
    'label'    => false,
    'error'    => [
        'attributes' => ['class' => 'col-xs-12 error-message inline']
    ],        
]);   
?>

Answer 2

我会尝试传递div选项。

<?php
echo $this->Form->input('regions', [
    'div' => [
        'class' => 'checkbox col-xs-4'
    ]
]);
?>

但您可能最终需要更改input field template。
