Question

This is my code in smarty:

{if $cat!="1_5"} do something {/if}

If I add additional condition with or:

{if $cat!="1_5" or $cat!="2_30"} do something {/if}

Then it doesn’t work in proper way. Why? Is this possible to use in one brackets two or more inequality conditions?

Answer 1

Alright, so we have the categories 1_5 and 2_30

let’s see what happens in your if-condition when $cat="2_30"

$cat!="1_5"     $cat!="2_30"                    $cat!="1_5"    $cat!="2_30"
       |         |                                    |         |
     TRUE      FALSE                                TRUE      FALSE
        \       /                                      \       /
         \     /                   but:                 \     /
          \   /                                          \   /
            OR                                             AND
            |                                               |
          TRUE                                            FALSE
     //do something                                //don't do something

So, you get the idea 🙂 You have to use AND instead of OR:

{if $cat!="1_5" and $cat!="2_30"} do something {/if}
