Question

I have my website working on social engine, I have a Main page named as articles.tpl, and in that I have a sub-page named as article.tpl, article.tpl is used to show the entire article, and articles.tpl is used to show topics of articles not the content,

My concern is with articles.tpl(pretty confusing articles and article)
In articles.tpl, 3 articles title, author of article and date is displayed, but I also want to display the category of that article,

For that I tried the following code,

$article_category = "";
$parent_category = "";
$article_category_query = $database->database_query("SELECT articlecat_id, articlecat_title, ".
        "articlecat_dependency FROM se_articlecats WHERE articlecat_id='".
        $rc_article->article_info[article_articlecat_id]."' LIMIT 1");

if($database->database_num_rows($article_category_query) == 1) {

    $article_category_info = $database->database_fetch_assoc($article_category_query);

    $article_category = $article_category_info[articlecat_title];

    if($article_category_info[articlecat_dependency] != 0) {

    $parent_category = $database->database_fetch_assoc(
            $database->database_query("SELECT articlecat_id, articlecat_title".
            " FROM se_articlecats WHERE articlecat_id='".
            $article_category_info[articlecat_dependency]."' LIMIT 1"));
    }
}
$smarty->assign('article_category', $article_category);

and in articles.tpl file I called it in this way

<span class="tahoma11_blue">|  {$article_category}</span>

But when I check I get nothing, that space is blank, I am just able to see

How can I display the category?

Answer 1

i think you have to change

$smarty->assign('categories', $categories);

to

$smarty->assign('article_category', $article_category);

(in your example, you assign the (apparently empty) php variable $categories to the smarty variable categories. then, in the template, you use a smarty variable article_category – which never got assigned)
