Event Triggering in CakePHP

I am struggling with the onChange event in this code snippet. I must have overlooked something because it's not functioning as expected. Can someone please point out my mistake? Your assistance is greatly appreciated:

<td class="cellInput">
  <?php
    $options = array('200'=>'200', '500'=>'500', '1000'=>'1000', '2000'=>'2000', '5000'=>'5000', 'Outro'=>'Outro');
    $attributes = array('legend' => false);

    echo $form->select('capacidade', $options, array(
      'class' => '',
      'label' => '',
      'default' => '200',
      'onchange' => "javascript:checkForOther(this);",
    )); 
  ?>
</td>

Answer №1

Following the recommendations of others, it is important to correctly place the attributes in their parameter positions. Additionally, I suggest removing the javascript element and instead only including the function name like this:

Before: 

'onclick' => "javascript:validateForm(this);"

After: 

'onclick' => "validateForm(this)"

Answer №2

Give it a shot

  1. Consider moving the attributes to the fourth parameter instead of the third:

    echo $form->select('capacidade', $options, null, 
    array(
        'class'=>''
        ,'label' => ''
        ,'default' => '200'
        ,'onchange' => "javascript:checkForOther(this);"
    )
);

  2. Check if the generated page source includes the onChange attribute?

  3. Take a look at the reference guide

Answer №3

Based on the CakePHP select method documentation, it states that the third parameter is utilized to designate the default selected option.

In order to include HTML attributes to a select element, you must utilize the fourth parameter:

<td class="cellInput">
  <?php
  $options = array('200'=>'200', '500'=>'500', '1000'=>'1000', '2000'=>'2000', '5000'=>'5000', 'Outro'=>'Outro');
  $attributes = array('legend'=>false);
  echo $form->select('capability', $options, '200', array('class'=> '', 'label' => '', 'onchange' => "checkForOther(this);")); 
  ?>
</td>
