If image exists...

How do we do an if then statement in smarty such as...

Code:

if image exists then display image



else do nothing

I know this has to be pretty simple.

Can anyone help? Funky?

Thanks, John7

Okay - there is not a standard smarty or xcart way of doing this but.... :)

first:

create a new modifier file: modifier.file_exist.php and save it into your smarty plugins folder.

Code:

<?php 

/* 

* Smarty plugin 

* ------------------------------------------------------------- 

* Type:     modifier 

* Name:     file_exists 

* Purpose:  checks if a file exist 

* ------------------------------------------------------------- 

*/ 

function smarty_modifier_file_exists($params, &$smarty) 

{ 



    extract($params); 



    if (empty($file)) { 

        $smarty->trigger_error("assign: missing 'file' parameter"); 

        return; 

    } 



    return file_exists($file); 

} 

?>

Then in the template where you wish for the file check to be used:

{assign var="file" value="the_image_check_for.gif"}
{if $file|file_exists}
[img]{$file}[/img]
{else}
Show another image
{/if}

That'll do it :)

Awsome!!!

I'm going to go test it out now.

I'll keep you posted on how this turns out!

Thanks Funky!!!
