i'm a little confused about how labels & inputs are assigned for/id pairs
in FormHelper.
Here's the code i have (it's inside a foreach of an entity collection):
$attrId = 'Listing.ItemAttr.' . $attr->id;
echo
$this->Html->div('columns small-16 medium-8',
$this->Form->label($attrId, // [for] attribute
$this->Form->checkbox(
$attrId, // [name] attribute
[
'id' => $attrId, // [id] attribute - if i skip this for checkbox
inputs, i don't get an [id] attribute.
// 'label' => $attr->name >> turns into <input type="checkbox"
label="Attribute Name">
// other checkbox attributes
]
) . $attr->name,
[
'escape' => FALSE
]
) // end label
);
The resulting HTML:
<div class="columns small-16 medium-8">
<label for="listing-itemattr-3">
<input type="checkbox" id="Listing.ItemAttr.3" name="
Listing[ItemAttr][3]">Attribute Name
</label>
</div>
The label passes the [for] attribute through FormHelper::_domId, which i'd
expect. But the [id] attribute doesn't appear to get the same treatment. i
changed the checkbox() call to input() and the same ID string was assigned.
It looks like an auto-generated ID is passed through _domId, but that only
gets into the attributes if 'id' isn't already set in that array.
i also discovered that in the checkbox() method, a 'label' key is turned
into an attribute of the input, not used to generate a wrapping <label>
element as with most other inputs. Peculiar. So i'm doing this manual
structure (which is fine, i also need to customize some other parts of the
HTML anyway).
*Question 1*: In FormHelper::input(), shouldn't the ID attribute be
adjusted with _domId *after* the $options array is complete? Or is there an
issue in checkbox() that it's not outputting the generated ID to HTML?
*Question 2*: Any suggestions how to get the wrapping label's [for] to
match the checkbox's [id] until one of the above is addressed?
Thanks.
