PHP code (functions.php) $main = $db_sql->query_array(SELECT catid,titel,subcat,startorder FROM $cat_table WHERE catid=’$subcat’); $tpl->register(‘category_title’,stripslashes($main[‘titel’])); $tpl->register(‘category_id’,$main[‘catid’]); So

PHP code (functions.php)

$main = $db_sql->query_array("SELECT catid,titel,subcat,startorder FROM $cat_table WHERE catid='$subcat'");
$tpl->register('category_title',stripslashes($main['titel']));
$tpl->register('category_id',$main['catid']);

So I want to add an if statement where if {category_id} is not 0 then do the following code

<img src="{GRAFURL}/{category_id}.jpg" alt="{category_title}" width="50" height="50" border="0" align="middle" />&nbsp;{category_title}

what would be the correct syntax?

need more code still for the html file?

    HTML doesn’t have dynamic features like if-statements. Think of HTML as a language to define a layout – unchangeable using HTML itself.

    This should do the trick:

    <?php

  if ( false === is_empty( $category_id )) {

    echo  "<img src='{$GRAFURL}/{$category_id}.jpg' alt='{$category_title}' 
            width='50' height='50' 
            border='0' align='middle' />&nbsp;{$category_title} ";

  }

?>

    In case you need to add client-side dynamic features to your HTML-pages, have a look at jQuery or jQuery UI.
