form.select ViewHelper <f:form.select>

This ViewHelper generates a <select> dropdown list for the use with a form.

Basic usage

The most straightforward way is to supply an associative array as the options parameter. The array key is used as option key, and the value is used as human-readable name.

Basic usage:

<f:form.select name="paymentOptions" options="{payPal: 'PayPal International Services', visa: 'VISA Card'}" />
Copied!

Pre select a value

To pre select a value, set value to the option key which should be selected. Default value:

<f:form.select name="paymentOptions" options="{payPal: 'PayPal International Services', visa: 'VISA Card'}" value="visa" />
Copied!

Generates a dropdown box like above, except that "VISA Card" is selected.

If the select box is a multi-select box multiple="1", then "value" can be an array as well.

Custom options and option group rendering

Child nodes can be used to create a completely custom set of <option> and <optgroup> tags in a way compatible with the HMAC generation. To do so, leave out the options argument and use child ViewHelpers:

Custom options and optgroup:

<f:form.select name="myproperty">
   <f:form.select.option value="1">Option one</f:form.select.option>
   <f:form.select.option value="2">Option two</f:form.select.option>
   <f:form.select.optgroup>
      <f:form.select.option value="3">Grouped option one</f:form.select.option>
      <f:form.select.option value="4">Grouped option twi</f:form.select.option>
   </f:form.select.optgroup>
</f:form.select>
Copied!

Usage on domain objects

If you want to output domain objects, you can just pass them as array into the options parameter. To define what domain object value should be used as option key, use the optionValueField variable. Same goes for optionLabelField. If neither is given, the Identifier (UID/uid) and the __toString() method are tried as fallbacks.

If the optionValueField variable is set, the getter named after that value is used to retrieve the option key. If the optionLabelField variable is set, the getter named after that value is used to retrieve the option value.

If the prependOptionLabel variable is set, an option item is added in first position, bearing an empty string or - if provided, the value of the prependOptionValue variable as value.

Domain objects:

<f:form.select name="users" options="{userArray}" optionValueField="id" optionLabelField="firstName" />
Copied!

In the above example, the userArray is an array of "User" domain objects, with no array key specified.

So, in the above example, the method $user->getId() is called to retrieve the key, and $user->getFirstName() to retrieve the displayed value of each entry.

The value property now expects a domain object, and tests for object equivalence.
