Hey there!

I'd like to be able to do the following within a template file but fail
with loads of smarty compiling errors:

Code:
{assign var="editable" value=`$cond1 eq "yes" and $cond2 eq "no"`}


I already tried to put the value part in " instead of ` but failed,
also an {eval var="" assign=""} doesn't work here.

I only like to assign the editable variable once and then use it in
several {if $editable} ... {/if} statements.
The only workaround I know for now is to do the evaluation inside the
calling PHP script.

Tommy.

I wonder what you think that should do.

Perhaps you want this:
Code:

{if $cond1 eq "yes" and $cond2 eq "no"}
    {assign var="editable" value=true}
{else}
    {assign var="editable" value=false}
{/if}

Unfortunately, the simple math facility in Smarty does not support booleans, so while you could store $cond1 and $cond2 more conveniently as booleans, you still could not do the following:
Code:
{assign var="editable" value=$cond1&~$cond2}

So, the only option I can think of is to either use a math trick, write a custom modifier to deal with your logic evaluation, or issue the logic in your PHP file and only send fully qualified parameters to your Smarty template.

In the first case, you also set your conditionals to booleans and you do something on the order of:
Code:
{assign var="editable" value=$cond1-$cond2}

Thus,
if $cond1 == true (1) - $cond2 == false (0) == 1
if $cond1 == true (1) - $cond2 == true (1) == 0

if $cond1 == false (0) - $cond2 == false (0) == 0
if $cond1 == false (0) - $cond2 == true (1) == -1

and $editable == 1 would satisfy your condition.

The other options should be more self-explanatory. Anything more than that I can not think of, I must sadly say.

Good luck!
