This is the old documentation center for eZ Publish 4. We are currently migrating the eZ Publish documentation to http://confluence.ez.no the eZ Publish 5 documentation platform. Documentation for the eZ Publish legacy components are still located on this site, as well as all documentation for earlier releases.

while

Summary

Creates a while loop.

Usage

{while <condition> [ sequence <array> as $seqVar ]}
    [ {delimiter}...{/delimiter} ]
    [ {break}    ]
    [ {continue} ]
    [ {skip}     ]
{/while}

Description

This construct is the simplest loop mechanism that the template language offers. It tells eZ Publish to execute the nested statement(s) repeatedly, as long as a given expression evaluates to TRUE. The value of the expression is checked for every loop iteration (at the beginning of the iteration). If the given expression evaluates to FALSE from the very beginning, the nested statement(s) will not be executed.

Examples

Example 1

{while ne( $counter, 8 )}
 
    Print this line eight times ({$counter}) <br />
    {set $counter=inc( $counter )}
 
{/while}

If the initial value of $counter is zero, the following output will be produced:

Print this line eight times (0)
Print this line eight times (1)
Print this line eight times (2)
Print this line eight times (3)
Print this line eight times (4)
Print this line eight times (5)
Print this line eight times (6)
Print this line eight times (7)
