You'll be happy to know that you can use php functions as modifiers. Because of the way that the explode function takes its parameters, you have to do it this way, though:

{", "|explode:$var_to_explode}

HOWEVER, why not do that work from you PHP application code?

HTH

you mean have a php function like

function format_review($stringreview){
//function that formats the string into an array

return explode(":", $Stringreview);

}

in my php file.

but how do i call it in the tpl file

I get my string through this call in the tpl file

{assign var="nextReview" value=$article->getStory()}

can i just assign an array var and call the function like this

{assign var="arrayReview value=$this->format_array($nextReview)}

??

Well, not exactly Smile

It looks like you are doing operations in your template that could be considered "application" logic as opposed to display logic. Usually, a good indication of that is trying to model or transpose data in your template.

Without getting into a debate as to what should go where, the syntax I proposed in my first post should work from your template if you do it from an assign (it was only a demonstration of the syntax the way I originally posted it):

{assign var=foo value=", "|explode:$var_to_explode}

Alternatively, I would suggest that you can add a new method or augment your existing one in your $article object to return an array of the proper structure.

However, a common practice would be to do all data modeling assignment work prior to calling your template and use $smarty->assign() to pass the intended structures instead of relying on your template to do so.

I understand what you mean about the display logic and the application logic now that i have had a bit of a read at smarty manual.

I was just asked to change the way a (long) string was output to the display and the code that was there used lots and lots of replace which i thought was a bit of a hack, so thought put it in a wee array then output it.

thanks for the help prob write a new method in the $article object (later)

however since your line of code works and I am wanting to get this done and dusted for today i will use that just now.

(and i slaged the last code for beeing a hack!!!)

cheers
