Question

I have assigned a variable based on the number of characters in a name, which returns an integer (1,2,3, etc). I would like to further add an {if} statement to show an option if the option name matches the variable. The option names are 5″ x 7″ – 1, 5″ x 7″ – 2, 5″ x 7″ – 3 etc.

{assign var="numberofcharacters" value=$smarty.get.name|count_characters}

{if $vr.variant_name == '5" x 7" - $numberofcharacters' || $vr.variant_name == '8" x 11" - $numberofcharacters'}
...
{/if}

This is not producing a result, even though I have 3 options that should be showing. Please could somebody let me know what is wrong with my {if} statement?

I cannot use:

{if $vr.variant_name|contains:}

because if the value returned is 1, then 10, 11 and 12 are also included when I just need 1 included.

MANY THANKS

Smarty3 with escaped quotes:

{$numberofcharacters = 1}
{$var = "5\" x 7\" - {$numberofcharacters}"}
{$var}

or

{$numberofcharacters = 1}
{$name = '5" x 7"'}
{$var = "{$name} - {$numberofcharacters}"}
{$var}

or Smarty2

{assign var="numberofcharacters" value=1}
{assign var="name" value='5" x 7"'}
{assign var="var" value="`$name` - `$numberofcharacters`"}
{$var}

or using the cat modifier

{assign var="numberofcharacters" value=1}
{assign var="name" value='5" x 7"'}
{assign var="var" value=$name|cat:" - "|cat:$numberofcharacters}
{$var}

throwing things together should be easy enough…

{$numberofcharacters = 1}
{$five_seven = "5\" x 7\" - {$numberofcharacters}"}
{$eight_eleven = "8\" x 11\" - {$numberofcharacters}"}
{if $vr.variant_name == $five_seven || $vr.variant_name == $eight_eleven}
  …
{/if}

But… If you have a fixed pattern you want to check, you might want to use a regular expression instead? or a substr?

{$variant_name = '5" x 7" - 123'}
{if preg_match('/^5" x 7"|^8" x 11"/', $variant_name, $tmp)}
  hello world
{/if}

(you should do stuff like that in your PHP though…)
