Index within an Array

Lets say I have an array of articles, I will make a loop and when accessing element 1 I
would like to print out the name of the first item and the name of the third item (offset
from the first)

something like:

item[index].name
and
item[index+3].name


	{section var=child loop=$list_items}

		// item within the loop
		{$child.name} //How to access the index?

		// offset from the current item being looped
		{$child.name} //How to access the index of the third [index+3] ?
	
	{/section}

I would like to understand how to access elements from an array using somekind of indexing.

Please help!

Hi Jorge

If you're using eZ publish 3.6 or newer, I would suggest to use foreach instead of section (it is deprecated). You will find examples of how to use foreach in the technical manual: http://ez.no/doc/ez_publish/technical_manual/3_7/reference/template_control_structures/looping/foreach

The technical manual also contains more information on accessing array elements: http://ez.no/doc/ez_publish/technical_manual/3_7/templates/the_template_language/variable_usage (search for "index lookup")

Good luck!
