 Posted: Thu May 19, 2016 3:11 pm Post subject: Limit Foreach Results within a Section Loop |
 |
|
I have a piece of code for my article section that returns the Topic and all Articles associated to that topic. I want to limit the number of articles displayed to only 3 per topic. How can I achieve this?
*I tried using an iteration and break, but it only would show 3 articles on 1 topic.
| Code: | {section name=TopicsList loop=$TopicsList}
<p>{$TopicsList[TopicsList].topic_name}</p>
{foreach $ArticlesList as $i}
{if $i.article_topic_id == $TopicsList[TopicsList].topic_id}
<p>{$i.article_title}</p>
{/if}
{/foreach} |

| Why you pass more than 3 articles to the template to begin with? |

I guess it is just a grab everything function.
| Code: | function getArticlesList() {
return
getSqlResult(
"select * from article order by article_topic_id, article_title",
SQL_RESULT_ALL);
} |
I used to just show all articles, but the article list is getting too big, so I need to limit it now. |

Then fix your PHP code, instead of wasting time trying to do everything in a template.
Next time you'd ask Smarty to make coffee and bake cookies at this rate. |
