The following code shows, how I tried to modify single elements of an array and the result.
{def $myarray=array(5,7,9)}
myarray = {$myarray[0]}, {$myarray[1]}, {$myarray[2]}<br>
or: {$myarray.0}, {$myarray.1}, {$myarray.2}<br>
loop display:<br>
{foreach $myarray as $ma}
myarray-element: {$ma}<br>
{/foreach}
{set $myarray.0=20} {* WHY DOESNT IT WORK?*}
now the array is destroyed<br>
myarray = {$myarray[0]}, {$myarray[1]}, {$myarray[2]}<br>
{foreach $myarray as $ma}
myarray-element: {$ma}<br>
{/foreach}
{* result not better using an associative array*}
{def $myassocarray=hash('first', 'a',
'second', 'b',
'third', 'c')}
myassocarray = {$myassocarray.first}, {$myassocarray.second}, {$myassocarray.third}<br>
myassocarray(alt) = {$myassocarray[first]}, {$myassocarray[second]}, {$myassocarray[third]}<br>
{set $myassocarray.first='x'}
myassocarray(changed) = {$myassocarray.first}, {$myassocarray.second}, {$myassocarray.third}
The result was:
myarray = 5, 7, 9
or: 5, 7, 9
loop display:
myarray-element: 5
myarray-element: 7
myarray-element: 9
now the array is destroyed
myarray = , ,
myassocarray = a, b, c
myassocarray(alt) = a, b, c
myassocarray(changed) = , ,

Hi E As you most likely have found out by now assigning a new value to an array element is not possible directly. This fact is hidden quite well in the docu:
The "set" function can not be used to change the value of an element/attribute of an array, hash or an object. In fact, the elements/attributes of arrays, hashes and objects can not be changed from within template code.
http://ez.no/doc/ez_publish/technical_manual/3_8/templates/the_template_language/variable_usage So best write yourself a custom template operator that does the job, it is really easy to do. First check the contribution section though, maybe there is already such an operator there. Claudia
