[Hydrator][ZF2] Dynamically adding new objects

[JordyvA]

I’ve a problem with my collections. I’ve followed the example tutorial (https://github.com/doctrine/DoctrineModule/blob/master/docs/hydrator.md#a-complete-example-using-zendform) and have succesfully made a Blogpost and Tag entity. In my controller I’ve an add action and edit action. My add and edit views:

echo $this->formElement($blogpost->get('addTag'));
$tag = $blogpost->get('tags');

?>
<fieldset id="tagFieldset">
    <?php
        echo $this->formCollection($tag);
    ?>
</fieldset>

The view has a button for adding tags dynamically (like in this example: http://zf2.readthedocs.org/en/latest/modules/zend.form.collections.html#adding-new-elements-dynamically), which works fine in the edit-action. When adding a new blogpost with 2 tags at the same time, it only adds 1 tag in the database (the count option is set to 1. When I increase this number, it is able to add tags according to the option). When I edit that blogpost and add 2 tags (total of three), 2 tags are added to the database.

When debugging the addTags() function, the parameter holds only 1 Tag object at the add-action. In the edit-action it holds all the new tags that have been added (in my case, 2 new tags).

My blogpostFieldset look likes:

$this->add(array(
    'name' => 'addTag',
    'type' => 'button',
    'options' => array(
        'label' => 'Add more tags',
    ),
    'attributes' => array(
        'id' => 'addTag'
    )
));

$tagFieldset = new TagFieldset($serviceManager);
$this->add(array(
    'type'    => 'Zend\Form\Element\Collection',
    'name'    => 'tags',
    'options' => array(
        'count'           => 1,
        'target_element' => $tagFieldset,
        'should_create_template' => true,
        'allow_add' => true,
    )
));

And my javascript:

$('#addTag').click(function(e) {
        var currentCount = $('form > #tagFieldset > label').length;
        alert(currentCount);
        //Set datatemplate (generated by the arraycollection)
        var template = $('form > #tagFieldset > span').data('template');

        //Replace the template to other addressfieldset
        template = template.replace(/__index__/g, currentCount);

        //Set new fieldset
        $('form > #tagFieldset').append(template);
    });

It renders my templates correctly. Works fine in my edit-action, but my add-action only add 1 tag. I’ve no idea why. Maybe that the add-action doesn’t recognize the dynamically created fields?

I'm closing this - we're unable to provide support on such very localized questions.

Please insulate the problem first, then report it as issue once confirmed and when you have a simplified example that does not involve view helpers and js.
