Unable to get submit action to occur in TYPO3 Fluid contact form - forms

Question

We are trying to manage to get a simple contact form running. But regardless of what we try, we get nothing at all.
The form itself is on the front-end and configured like this :
<f:section name="Main">
<div class="ext-frame container">
<h2>{record.header}</h2>
<f:form action="submit" name="order" object="{order}" class="form-horizontal">
<f:for each="{settings.offer}" as="obj" key="id">
<div class="row offer">
<f:if condition="{obj.offer.img}">
<f:then>
<div class="col-sm-4 col-md-4 offer-img-container">
<img src="../{obj.offer.img}" class="offer-image" alt="{obj.offer.img.alternative}" />
</div>
</f:then>
</f:if>
<div class="col-sm-8 col-md-8 {f:if(condition: '{obj.offer.img} == \'\'', then: 'col-sm-offset-4 col-md-offset-4')}">
<label class="offer-label">
<f:form.radio property="offer" value="{id}" />
<div class="pull-right">
<p class="lead">
{obj.offer.title}<br/>
<small>{obj.offer.subtitle}</small>
</p>
<p class="small">{obj.offer.description}</p>
</div>
</label>

In our ContentController.php there is also a submitAction given but it seems that this Action is never called :
public function submitAction() {
echo 'Testoutput';exit;
}

Answer 1

Where does the form lead you after submitting? Check out the final HTML action="" if everything is correct.
Try to set the form "method" to POST. I've just had some problems with forms using GET because the target PID got lost for unknown reasons so I had to add a <input type="hidden" name="id" value="{targetPid}" /> to get it working.
