Smarty "or" variable?

[cwp +]

I'm trying to do the <title> modification, but I'm unsure how to do "or" statements with smarty tags.

Like this

{if $body=='viewlisting2.tpl'}
<title>my custom title</title>
{if $body=='categories/browse.tpl'}
<title>my custom title</title>
{/if}
{else}
<title>{$sitetitle}</title>
{/if}

{if $body=='viewlisting2.tpl'}
<title>my custom title</title>
{/if}
{if $body=='categories/browse.tpl'}
<title>my custom title</title>
{else}
<title>{$sitetitle}</title>
{/if}

I've tried many different methods but none of them work just right. The 2nd method works, but shows the original sitetitle with both variables.

I checked out the official smarty site and couldn't find anything on "or" variables. I know this can be done with PHP, just wanted to make sure this can't be done with just smarty first.

The easiest thing I have found when having trouble wrapping your mind around something is to just write it out in simple english. Then convert it to code later.

In your second example you are saying.....


if the body variable equals viewlisting2.tpl then the title should be my custom title.

and immediatly after it you say.....

if the body variable equals categories/browse.tpl then the title should be my custom title AND if its not it should just be the site title.

By the time it does the second evaluation its already done the first and thats why your getting the title twice.

Things within a single {if} {/if} get evaluated together and only the correct outcome is displayed. In your second example you have 2 different {if} {/if} sections but only the second has an {else} in it. This means that in total you are evaluating the body 2 times and displaying results 2 times. You need to have all the evaluations in a single group OR have indivudual evaluations that only display if the evaluation is true so that you wont have duplicate output.

Something like this would evaluate the the body variable and compare it to 2 options, if it doesnt matche either it will use the last one after the else....

{if $body=='viewlisting2.tpl'}
<title>my custom title</title>
{elseif $body=='categories/browse.tpl'}
<title>my custom title</title>
{else}
<title>{$sitetitle}</title>
{/if}

{else if

is exactly what I was looking for.. I should have asked it out in a simpler language!

Thanks again.
