Hi,

I could do with some advice on templating a custom snippet. The snippet below outputs rows from a custom database table. It uses a rowTpl and rowClass set as parameters in the snippet call.

How would I go about adding a 'outerTpl'. I need to be able to output the rows using a placeholder in a 'outerTpl' chunk?

I can get the outerTpl chunk to display, but can't get the foreach loop output to replace the placeholder.

Snippet Code:

// add package so xpdo can be used:
$path = MODX_CORE_PATH . 'components/its/';
$result = $modx->addPackage('its',$path . 'model/','modx_');

//$isbn = parameter value passed from snippet call
//$outerTpl = parameter value passed from snippet call
//$rowTpl = parameter value passed from snippet call
//$rowClass = parameter value passed from snippet call
//$altClass = parameter value passed from snippet call

$rows = $modx->getCollection('ITS',array('isbn'=>$isbn));
$outerTpl = $modx->getOption('tpl',$scriptProperties,'itsTpl');
$rowTpl = $modx->getOption('rowTpl',$scriptProperties,'itsRowTpl');
$rowClass = $modx->getOption('rowClass',$scriptProperties,'white');
$altClass = $modx->getOption('altClass',$scriptProperties,'brown');

$i = 0; //Starts row count at 0

$output = $modx->getChunk($outerTpl,$resourceArray);

foreach($rows as $row) {
   if($i % 2 == 0){
     $itsClass = $rowClass;
   }else{
     $itsClass = $altClass;
   }
   $resourceArray = $row->toArray();
   $resourceArray['itsClass'] = $itsClass;
   $rowOutput .= $modx->getChunk($rowTpl,$resourceArray);
   $i++;
}

return $output;

Any help or advice would be great!

Many Thanks

Hi romanum,
Before returning the output, pass your processed rows to the outerTpl chunk (as a placeholder) and return the outerTpl.

$i = 0; //Starts row count at 0
 
foreach($rows as $row) {
   if($i % 2 == 0){
     $itsClass = $rowClass;
   }else{
     $itsClass = $altClass;
   }
   $resourceArray = $row->toArray();
   $resourceArray['itsClass'] = $itsClass;
   $rowOutput .= $modx->getChunk($rowTpl,$resourceArray);
   $i++;
}

$rowsPlaceholder = array('rows' => $rowOutput);
$output = $modx->getChunk($outerTpl,$rowsPlaceholder); 
return $output;

In your outerTpl, you should now have the Placeholder

[[+rows]]

to Output your Rows.
