Very strange on if query

Tuesday 29 August 2006 4:14:43 am

On a template, I wanna to catch the value of $p, so I define at the begining

{if eq($p,'')}
  { set $p = 1 } 
      Testing
 {/if}

for if cannot catch $p, $p will be set the default value as 1, and print Testing

and when I run the template, testing was printed, but the value of $p haven't been set, why?.....

and when I add some code as

{if eq($p,'')}
  { set $p = 1 } 
      Testing


 {/if}

{if eq($p,'')}
  
      Testing2


 {/if}

only Testing 2 was print, so strange

the full code of this template is attached

{if eq($p,'')}

  { set $p = 1 } 
      Testing


 {/if}
             
{if eq($p,'')}
  
      Testing2


 {/if}


{let news=fetch(content,list,hash(parent_node_id,73,
                                       limit, 10, 
                                       sort_by,  array( published, false() ), 
                                       offset,$view_parameters.offset,
                                       class_filter_type,include,
                                       class_filter_array,array('17'))) 
$pages = ceil(div(count($news),3))

}




Pages: <
{for 1 to $pages as $page}

<a href={concat('content/news_display?p=',$page)|ezurl()}>{$page}</a>

{/for} > Page: {$p}    </br>

  {if ge(count($news),mul($pages,3))}

 {for sub(mul($p,3),3) to sub(mul($p,3),1) as $index}
               <a href={$news[$index].url_alias|ezurl}>  {$news[$index].object.data_map.title.content|wash}  </a></br>
             {$news[$index].object.data_map.intro.content|wash}  </br></br>
                 {/for}

  {else}
{for sub(mul($p,3),3) to sub(count($news),1) as $index}
               <a href={$news[$index].url_alias|ezurl}>  {$news[$index].object.data_map.title.content|wash}  </a></br>
             {$news[$index].object.data_map.intro.content|wash}  </br></br>
                 {/for}

 {/if}
