    text
    copied!<p>Based on the Zend Framework 2 manual (<a href="http://framework.zend.com/manual/2.2/en/modules/zend.form.collections.html" rel="nofollow">here</a>) I made a form like this:</p> <pre><code>class ParentForm extends Form { public function init() { $this-&gt;setName('parent_form') -&gt;setAttribute('method', 'post') -&gt;setHydrator(new ClassMethods(true)) -&gt;setInputFilter(new InputFilter()); $this-&gt;add(array( 'type' =&gt; 'Application\Form\Fieldset\Parent', 'name' =&gt; 'parent', 'options' =&gt; array( 'label' =&gt; 'Parent', 'use_as_base_fieldset' =&gt; true ) )); $this-&gt;add(array( 'type' =&gt; 'Zend\Form\Element\Csrf', 'name' =&gt; 'csrf' )); $this-&gt;add(array( 'name' =&gt; 'submit', 'attributes' =&gt; array( 'type' =&gt; 'submit', 'value' =&gt; 'Send' ) )); } } </code></pre> <p>And the 'parent' fieldset:</p> <pre><code>class ParentFieldset extends Fieldset { protected $count = 2; public function init() { $this-&gt;setName('parent_fieldset') -&gt;setHydrator(new ClassMethodsHydrator(false)) -&gt;setObject(new Model\Parent()); $this-&gt;add(array('type' =&gt; 'Element\MyField')); $this-&gt;add(array( 'type' =&gt; 'collection', 'name' =&gt; 'children', 'options' =&gt; array( 'label' =&gt; 'Children', 'count' =&gt; $this-&gt;count, 'should_create_template' =&gt; true, 'allow_add' =&gt; true, 'target_element' =&gt; array( 'type' =&gt; 'Application\Form\Fieldset\Child', 'name' =&gt; 'child', 'options' =&gt; array( 'label' =&gt; child', ), ), ) )); } public function setCount($count) { $this-&gt;count = max($count, 2); } } </code></pre> <p>This works great to hydrate my Parent object with data obtained from my form. A var_dump of the resuting object will look like:</p> <pre><code>object(Parent) public myField =&gt; foo public children =&gt; array =&gt; 0 =&gt; object(Child) public field1 =&gt; value1 public field2 =&gt; value2 .... 1 =&gt; object(Child) ..... 2 =&gt; object(Child) ..... </code></pre> <p>But I cannot figure out how to populate this multi-dimensional form with the above object if hydrated from the database (for editing purposes). How can I do that?</p> <p>Note: the count property in the form is set to the same number of children as in the object.</p>
