[Solved]How to access custom page content block value within UDT?

[neil-cmsms]

I've added a custom content block via my template {content block="my page data"} so that it now appears in my pages, as expected, when they are being edited - I enter data for "my page data" on each page.

I am writing a UDT that traverses the page hierarchy from the page it's on, and I want to get the value of the custom content block data. This must be easy to do but I have not been able to find the right object method or function I need online and it doesn't seem too obvious. The code I want to use is like like:

Code: Select all

$thisPage = $gCms->variables['content_id'];
$currentNode = &$manager->sureGetNodeById($thisPage);

while( isset($currentNode) && ($level=$currentNode->getLevel()) >= 0 )
{
  $pData = $currentNode->GetPropertyValue['my_page_data']; // This method does not seem to work
  if(strlen($pData)) { 
    if(strlen($data)) $data.= ","; 
    $data.= $pData ; 
  } 

  $currentNode =& $currentNode->getParentNode();
}

Can anyone help?
Thanks,
Neil

I also tried the following snippet to get pData and that did not seem to work either:

Code: Select all

  $smarty_data = "{content block='my_page_data'}";
  $smarty->_compile_source('temporary template', $smarty_data, $_compiled );
  @ob_start();
  $smarty->_eval('?>' . $_compiled);
  $pData = @ob_get_contents();
  @ob_end_clean();

Am I being stupid and missing something obvious here?
Thanks,
Neil

Try it

Code: Select all

/**
* gets page content block
*
* @param	string	$params['block']	(mandaroty). content clock.
* @param	string	$params['page']	(mandatory). page alias or id.
* @param	string	$params['eval']	evaluate content.
*
* @return	string 	content of a block.
*/

$result = FALSE;
if (!empty($params['page']) && !empty($params['block'])){
	$contentops = cmsms()->GetContentOperations();
	$smarty = cmsms()->GetSmarty();

	$block = ( empty($params['block']))? 'content_en' : $params['block'];
	$page_id = $contentops->GetPageIDFromAlias($params['page']);

	if( !empty($page_id) ){
		$content = $contentops->LoadContentFromId($page_id, TRUE);
		if( is_object($content) )	{
			$result = $content->GetPropertyValue($block);
		}
	}

}
if (!empty($result) && !empty($params['eval'])){
	$smarty->_compile_source('temporary template', $result, $_compiled);

	@ob_start();
	$smarty->_eval('?>' . $_compiled);
	$result = @ob_get_contents();
	@ob_end_clean();
}
return $result;

Code: Select all

{get_content_block page='71' block='Image_1_Alt_lt' eval='1'}

Excellent, thanks!

I got it to work using the content object mentioned in the above code. The last section seems redundant though - the $result is correct without doing the $smarty->_compile_source part. Am I missing some case where this would not work without that code? It's interesting that the $result is the same whether that code is there or not.

Thanks,
Neil

It is required if you have smarty in content block, e.g you have {sitename}. By default parameter 'eval' is not set as a result smarty is not processed.

[neil-cmsms]

Ah, yes. The example usage call had eval set to 1 so I figured this was required in general (and I suppose it is, actually). My initial target was simple text - it was when I tried to process main content blocks that I found its real purpose.

Many thanks for the help!
