if

if — Conditional block, the syntax is very similar to the php one, allowing () || && and other php operators. which are if and elseif.

If any of those block contains an elseif statement, the content between {elseif} and {/*blockname*} (you do not need to close the elseif block) will be shown if the block’s condition has no been met

Additional Tplix operators and their equivalent php syntax are as follow:

  • eq → ==
  • neq or ne → !=
  • gte or ge → >=
  • lte or le → <=
  • gt → >
  • lt → <
  • mod → %
  • not → !
  • X is [not] div by Y → (X % Y) == 0
  • X is [not] even [by Y] → (X % 2) == 0 or ((X/Y) % 2) == 0
  • X is [not] odd [by Y] → (X % 2) != 0 or ((X/Y) % 2) != 0
Examples:

Where template is:


{if $name eq 'Fred'}
    Welcome Sir.
{elseif $name eq 'Wilma'}
    Welcome Ma'am.
{else}
    Welcome, whatever you are.
{/if}

{* an example with "or" logic *}
{if $name eq 'Fred' or $name eq 'Wilma'}
   ...
{/if}

{* same as above *}
{if $name == 'Fred' || $name == 'Wilma'}
   ...
{/if}

{* parenthesis are allowed *}
{if ( $amount < 0 or $amount > 1000 ) and $volume >= #minVolAmt#}
   ...
{/if}

{* you can also embed php function calls *}
{if count($var) gt 0}
   ...
{/if}

{* check for array. *}
{if is_array($foo) }
   .....
{/if}

{* check for not null. *}
{if isset($foo) }
   .....
{/if}

{* test if values are even or odd *}
{if $var is even}
   ...
{/if}
{if $var is odd}
   ...
{/if}
{if $var is not odd}
   ...
{/if}

{* test if var is divisible by 4 *}
{if $var is div by 4}
   ...
{/if}

{*
  test if var is even, grouped by two. i.e.,
  0=even, 1=even, 2=odd, 3=odd, 4=even, 5=even, etc.
*}
{if $var is even by 2}
   ...
{/if}

{* 0=even, 1=even, 2=even, 3=odd, 4=odd, 5=odd, etc. *}
{if $var is even by 3}
   ...
{/if}

If with more examples


{if isset($name) && $name == 'Blog'}
     {* do something *}
{elseif $name == $foo}
    {* do something *}
{/if}

{if is_array($foo) && count($foo) > 0}
    {* do a foreach loop *}
{/if}
