Testing the array for field content

[davo]

I have a number of pages brought back in the array and I want to test to see if each any one of the pages in the array has a certain field with content. I could probably loop through the array but seem to remember if there was a simpler method. I've tried the below which doesn't work:

$showcases = $pages->find("template=dmc_update_link, DMC_select=$pageid, parent=1209");

$countshowcases = count($showcases);
if (($countshowcases > 0) && ($showcases->DMC_update_doc !=="")) {
echo "					
					<a data-toggle='collapse' data-parent='#accordion' href='#collapsefour'  class='list-group-item active'><span class='glyphicon glyphicon-collapse-down'></span> Destination Showcases <span class='badge'>{$countshowcases}</span></a>
					<div id='collapsefour' class='panel-collapse collapse'>
					<div class='panel-body'>";
foreach ($showcases as $showcase)	{
					echo "<li class='list-group-item'><a href='{$showcase->DMC_update_doc->url}' target='_blank'>Showcase {$showcase->title}</a> </li>";
					}
					echo "</div></div>";
			}

How about this?

"fieldName!=''"

How about this?

"fieldName!=''"

 where do you mean to express that? I can't get it to filter

I think LostKobrakai is suggesting you add that to your selector. That way your PageArray only containes pages where that field has some value.

Optionally you could do:

$showcases->filter("fieldname!=''");
