Array append Problem

Wednesday 09 June 2004 6:03:42 am

I am having troubles dymanically adding items in an array using a loop as well. Can anybody shine a light on the above problem?

Hmm,

i was using the correct code, but it isn't working because I use a name for my section. Maybe you can help me with this code

{let my_array=array()}
{section loop=$current_node.object.related_contentobject_array}
{set my_array=$my_array|append($:item.data_map.positie.content.0)}
{/section}
{$my_array|count}
{/let}

this works, and count outputs 20. Adding the name (omitting it isn't an option right now)

{let my_array=array()}
{section name=Container loop=$current_node.object.related_contentobject_array}
{set my_array=$my_array|append($:item.data_map.positie.content.0)}
{/section}
{$my_array|count}
{/let}

This code, certainly is incorrect, but I can't get it to work (tried a godzillion syntatical variations ;-( )

are you certain this code is correct? I have tried this, and tried it again just now (copy-paste), but it doesn't seem to work. Count results in 0. I am using 3.3.5.

the following error is produced by the debugger.

Warning: eZTemplate:set Jun 09 2004 16:34:30 
Variable 'Container:my_array' doesn't exist, cannot set

I have previously tried to solve this by adding the container prefix on an trial and error basis, resulting in some marvelous errors, but never the count of 20 ;-(

You could omit the namespace altogether and use the new var= construct, eg:

{let my_array=array()}
{section var=Container loop=$current_node.object.related_contentobject_array}
{set my_array=$my_array|append($Container.data_map.positie.content.0)}
{/section}
{$my_array|count}
{/let}

Notice the new use of Container. The var parameter does away with namespaces...

Mm, runnig into some weird behaviour again, do any of you have an explanation for this?

The code should first initialize an array, then it should dynamically at items to this array, if the item doesn't already exist. The general idea is to fetch an objects position value, or assign the first available position number randomly, if the position is missing from the current object.
The second part of this code snipplet is behaving really weird

{let my_array=array()}
{section var=Container loop=$current_node.object.related_contentobject_array}
{section show=and(ne($Container.data_map.positie.content.0,''), ne($Container.data_map.positie.content.0, '0'))}
	{set my_array=$my_array|append($Container.data_map.positie.content.0)}
{/section}
{/section}

{section var=counter loop=20}
	{section show=$my_array|contains($counter)}
		{* do nothing *}
	{section-else}
		{set my_array=$my_array|append($counter)}
	{/section}
{/section}
{/let}

When I omit the section-else part, the function works. With the {section-else} part, it doesn't. The else part is executed once, an item is added to array. So far so good. However, now the {section show=$my_array|contains($counter)} always evaluates to true, and the new element in the array is updated with the value of $counter (although the else part of the loop is isn't executed??).

I am at a loss here.

Mm, solved it myself, but am wondering if this is by design or if it is a bug.

Instead of using $counter, I assign it to a variable

{let my_count = $counter}

and use my_count in the function.

When using $counter, it adds $counter itself to array, and then startupdating it in the array. So {$counter} prints the number, with let you can assign it, but with append you append the variable instead of it's value.
