Php – HTML snippet within Zend_Form

PHPzend-formzend-framework

I'm using Zend_Form as part of a simple signup process. In part 1 of 2 the user is able to upload a number of images. In part 2 – for each one of these images – I ask the user to add further details – an additional 4 text fields grouped together using addDisplayGroup. Within each display group I want to display a thumbnail of the uploaded image. I have generated these thumbs and all the processing is complete but i'm unsure what the best approach is for displaying the image within the relevant section. I guess its possible to create a custom form element to display this but somehow this feels like overkill considering the image is purely being used for display purposes. I also dont really want to replace $this->form->render() with a manual outputting of the form. Could this be achieved with a decorator maybe? I'm still fairly new to ZF so any ideas would be much appreciated.

Thanks.

You would use a custom decorator in your decorator stack for the display group. Or you could use the HtmlTag decorator.

You could extend Zend_Form.

Zend form is not good place for logic, only form representation.

So, Load all needed elements using model in controller and pass them to the form in contructor as parameters.

You might be interested by this section of the manual, which seems to be exactly about what you want to obtain : 23.4.3. Display Groups (quoting) :

Display groups are a way to create virtual groupings of elements for display purposes. All elements remain accessible by name in the form, but when iterating over the form or rendering, any elements in a display group are rendered together. The most common use case for this is for grouping elements in fieldsets.

This should allow you to have your form elements re-grouped in fieldsets, and each one of those can have its legend -- in your case, that would be "heading X".

Once your checkboxes have been added to the form, you should be able to re-group them by using something like this :

$form->addDisplayGroup(array('checkbox1', 'checkbox2', 'checkbox3'), 'firstgroup');
$form->addDisplayGroup(array('checkbox4', 'checkbox5', 'checkbox6'), 'fsecondgroup');

For the rendering part, I suppose it'll use Zend_Form_Decorator_Fieldset

Edit after the comment

To set the title of each group, you have to set its "legend", passing that as an option.

For example, here is a piece of code I found from an old project I worked on quite some time ago :

$form->addDisplayGroup(array(
    'idCategory',
    'date',
    // ...
    'tags', 
    'nbComments'
), 
'postmeta', 
array(
    'order' => 2,
    'attribs' => array(
        'class' => 'group',
        'legend' => 'Meta-données'
    )
));

The "Meta-données", from what I recall, is the "legend" used for the fieldset containing those elements.
