Hi guys,

What's the easier way to remove an element from an array (using the template language) when the item value (not the key) is know.

I've tried various loops, but can't seem to get it to work.

Thanks in advance !

Would this work (quickly written):

$knownValue=""
$newArray=array();

{section var=Item loop=$oldArray}

  {section show=ne($Item, $knowValue)}
    $newArray|append($Item)}
  {/section}

{/section}

{set oldArray=$newArray}

It uses an extra array for this...

Thanks a lot, Paul. BTW, here's the code I ended up with:

{let newArray=array()}
{section loop=$node.object.parent_nodes}
  {switch match=$:item}
  	{case match=128}
	{/case}
	{case}
		{let newArray=$newArray|append($:item)}
	{/case}
  {/switch}
{/section}
{/let}
