Hi!
what i need:
if my node's class name is "spot", I want to fetch his parent until parent's class name ="geopositionnement".
if this parent class type is not what I want, I have to find the parent of the parent ...until the class type is what I need.(u follow me?)

in 3.6 you can say:

{if eq( $object.class_name, "Spot" )}
	


{let mynode=fetch(content,node,hash(node_id,$main_node_id))}
 
     
   {while ne($mynode.object.class_name,"Geopositionnement")}
	{set mynode=$mynode.object.main_node.parent}
	
	{/while}
{$mynode.object.class_name}
{/if}

this code works perfectly in 3.6 or 3.7 versions but how can i do this in a 3.5 version without using the while loop?

for the if, i say:

{section name=if show=eq( $object.class_name, "Spot")}

but i can't do somethig like a while loop...
plz help..

Heya!

Here are some snippets:

{$top.name}

{section var=node loop=$top.children}
================
    {$node.name}
    {section var=obj loop=$node.children}

----------------
        {$obj.name}

{section var=el loop=$obj.object.list}
{$el}{delimiter}:{/delimiter}
{/section}

----------------
    {/section}

================
{/section}

{let selected_id_array=$attribute.content} 
{section var=Options loop=$attribute.class_content.options} 
{section-exclude match=$selected_id_array|contains( $Options.item.id )|not} {$Options.item.name|wash( xhtml )}
{delimiter}<br/>
{/delimiter}
{/section}
 {/let}

so basically it's the loop=.... what you need.

Have phun!

ps: just out of curiosity, why do you still code in 3.5?

hi clemens...
thanks for your reply.

first:
i try to code a while loop in 3.5 because of the php server version, and because I try to make an extension that could be used by each ez versions...

2ndly:
I spend more than 3 days on this loop.
no more results....
I dont see anything I could use in your reply (sory).
you say to use loop=
but loop=what?
do you have more informations?
thx in advance.

Ok, this code took me about 3 hours.. and lots of thinking.. because I'm not very familiar with the section, section-else code etc...(cause I started from 3.6) I've checked this code in 3.7, should work with 3.5 though.

Here is the solution:

{let node=fetch('content','node', hash('node_id','63'))}
{let nodetest=$node}
	{*loop as much as the depth of the current item of the tree, otherwise parent could be NULL*}
	{section loop=$node.depth}
		{switch match=$nodetest.object.class_name}
		{case match="Geopositionnement"}
			Geopositionnement: {$nodetest.object.class_name},{$nodetest.node_id}<br/>
			{*if the current class_name=Geopositionnement*}
			{set $nodetest=$nodetest.parent}
		{/case}
		{case}
			Not a Geopositionnement: {$nodetest.object.class_name},{$nodetest.node_id}<br/>
			{*the default case, if the current class_name != Geopositionnement*}
		{/case}
		{/switch}
	{/section}
{* at this point, $nodetest is filled with the last Geopositionnement in the tree, exactly the same as your code does (correct me if I'm wrong) *}
{/let}
{/let}

Greets and all the best,
Clemens
ps: please mark your topic title 'solved' if it's solved...

Ok, this code does exactly the opposite of what you want... that's the only thing you got to fix..now it goes up in the tree, as long as the parent = Geopositionnement, you need to make it so that it goes up the tree until it reaches the Geopositionnement, well at least.. does not do another replace of the $nodetest by it's parent, I'd say.. use a $match variable, so you can control it if you already found a match.

thx a lot Clemens.
this code is right.....

{switch match=$object.class_name}

     {case match="Spot"}
{let node=fetch('content','node', hash('node_id',$main_node_id))}


{let nodetest=$node}


        {*loop as much as the depth of the current item of the tree, otherwise parent could be NULL*}


        {section  loop=$node.depth}


                {switch match=$nodetest.object.class_name}


                {case match="Geoposition"}




                        {*if the current class_name=Geoposition*}

						
                        


                {/case}


                {case}



					{set nodetest=$nodetest.parent}
                        {*the default case, if the current class_name != Geoposition*}


                
				{/case}
{/switch}

{* at this point, $nodetest is filled with the last Geopositionnement in the tree, exactly the same as your code does (correct me if I'm wrong) *}
