|
|
Hello.
I have this php code: Code: |
$query = "SELECT * FROM article_cat";
$query = mysql_query($query);
echo mysql_error();
while ($row = mysql_fetch_array($query))
{
$article_cat[] = $row;
$query1 = "SELECT * FROM article WHERE cat='".$row['id']."'";
$query1 = mysql_query($query1);
echo mysql_error();
while ($row1 = mysql_fetch_array($query1))
{
$article[] = $row1;
}
}
$main->assign('article', $article);
$main->assign('article_cat', $article_cat);
|
and the template:
Code: |
{foreach item=article_cat from=$article_cat name=article_cat}
{$article_cat.name}<br>
{$article_cat.description}<br><br>
{foreach item=article from=$article name=article}
{$article.id}<br>
{$article.title}<br>
{/foreach}
{/foreach}
|

you should give your arrays and you loop-items different names. this:
{foreach item=article from=$article}
can cause problems, maybe you better choose
{foreach item=article from=$articles}
another point: you have to give your $articles-array another structure. if $article_cats is one array and $articles is another array, smarty cannot know easily, which categorie an article belongs to. consider something like this (untested):
[php:1:f47435c774]$query = "SELECT * FROM article_cat";
$query = mysql_query($query);
echo mysql_error();
$article_cats = array();
$articles = array();
while ($row = mysql_fetch_array($query))
{
$article_cats[] = $row;
$cat_id = $row['id'];
$query1 = "SELECT * FROM article WHERE cat='".$row['id']."'";
$query1 = mysql_query($query1);
echo mysql_error();
while ($row1 = mysql_fetch_array($query1))
{
$articles[$cat_id][] = $row1;
}
}
$main->assign('articles', $articles);
$main->assign('article_cats', $article_cats);
[/php:1:f47435c774]
this makes $articles an 2-dimensional array. each array key is an article_cat's id and each array value is itself an array of articles that belong in this article_cat.
in the template you can dump it like this then:
Code: | {foreach item=article_cat from=$article_cats}
{$article_cat.name}<br>
{$article_cat.description}<br><br>
{foreach item=article from=$articles[$article_cat.id]}
{$article.id}<br>
{$article.title}<br>
{/foreach}
{/foreach} |
