zend_form display group inside foreach
- by Mike
I want to create a display group generated from foreach() clause output. I can't seem to get the syntax correct.
Here's the business logic:
for each category row
find the associated fees
output the category description as a label
and the fees as radio buttons
then create a display group with the fees as the group elements
and the category description as the legend.
I then have a style sheet format the elements on the page.
and here's the code:
foreach ($categoryData as $categoryRow) {
$fees[$i] = new Zend_Form_Element_Radio("fees[$i]");
$fees[$i]->setDescription(strval($categoryRow['description']));
foreach ($feeData as $feeRow) {
if ($feeRow['categories_idCategory'] == $categoryRow['idCategory']){
$fees[$i]
->addMultiOption($feeRow['idFees'] . '-' . $feeRow['categories_idCategory'], $feeRow['amount'] . '-' . $feeRow['name']);
}
}
$fees[$i]->setRequired(TRUE);
$this->addElements(array($fees[$i]));
$this->addDisplayGroup($feeRow['name'], 'feeGroup',array('legend' => strval($feeRow['description'])));
$i++;
}
I tried placing the addDisplayGroup() code within the foreach(), but I get the error:
Message: No valid elements specified
for display group
So, my guess is that I'm making some kind of novice mistake that you experts will spot right away. I appreciate your time and attention to this matter.
