Hi,

i need help. It does not work here:

{if segment_1=="produkte" AND segment_2==""}
{embed="global_embeds/.html_head" default_title="Produkte - {site_name}"}
<!--[if IE 7 ]> <body id="produkte" class="ie7> <![endif]-->
<!--[if IE 8 ]> <body id="produkte" class="ie8> <![endif]-->
<!--[if IE 9 ]> <body id="produkte" class="ie9> <![endif]-->
<!--[if (gt IE 9)|!(IE)]><!--> <body id="produkte"> <!--<![endif]-->
{embed="global_embeds/.global_header"}

some code

{if:elseif segment_1=="produkte" AND segment_2!=""}
  {if segment_2_category_id}
    {embed="global_embeds/.html_head" default_title="{segment_2_category_name} - {site_name}"}
<!--[if IE 7 ]> <body id="produkte" class="ie7> <![endif]-->
<!--[if IE 8 ]> <body id="produkte" class="ie8> <![endif]-->
<!--[if IE 9 ]> <body id="produkte" class="ie9> <![endif]-->
<!--[if (gt IE 9)|!(IE)]><!--> <body id="produkte"> <!--<![endif]-->
{embed="global_embeds/.global_header"}


some code

{exp:cat_info category_id="{segment_2}" invalid_input="alert"}{cat_info_cat_meta}{/exp:cat_info}


  {if:else}
    {embed="global_embeds/.html_head" title_postfix="&nbsp;- {site_name}"}
<!--[if IE 7 ]> <body id="produkt" class="ie7> <![endif]-->
<!--[if IE 8 ]> <body id="produkt" class="ie8> <![endif]-->
<!--[if IE 9 ]> <body id="produkt" class="ie9> <![endif]-->
<!--[if (gt IE 9)|!(IE)]><!--> <body id="produkt"> <!--<![endif]-->
{embed="global_embeds/.global_header"}

some code

  {/if}
{/if} 

I get “The value of the parameter “category_id” of exp:cat_info tag must be a number!”.
But the funny ting is that i also get it if i’m on:
mydomain.de/produkte

I’m using the latest EE2.

Hi,

Parameter category_id is required and it must be a category’s ID number. So, in case the variable {segment_2} does not output a number you get an alert because you set parameter

invalid_input="alert" 

If you plan that variable {segment_2} will sometimes output an empty string, set parameter

invalid_input="silence"

yes i set

invalid_input=“alert”

to see whats wrong

But i don’t understand why

{exp:cat_info category_id="{segment_2_category_id}" invalid_input="alert"}{cat_info_cat_meta}{/exp:cat_info} 

is executed in the place i put it.

Hi,

It is because for some reasons in ExpressionEngine complex conditionals are parsed very late.

Change your conditionals into simple ones or use Switchee instead of EE conditionals and that part of code will not be executed.
