Rpcms method of obtaining articles under the specified classification

I found a problem when doing the theme , It can't be said to be a problem , Just uncomfortable places .

Often the front page of the website is a display of articles of different categories in different modules , When making the homepage, I found that I didn't know how to get the articles under the specified classification .

Look at the rpcms Code of the default template , Discovery is the latest article 、 The hottest article encapsulates this functionality into a function , If you want to get the articles under the specified category, you need to change .

I found it on the Internet , notice rpcms There are sorted functions on the Forum , Just try it , Good , It also supports the acquisition of subcategories .

《 Sort out the common functions of templates 》 There are many other commonly used functions above , You can see if there is any demand .

function getLogsByCateId($id,$limit=10,$order=['a.upateTime'=>'desc']){
    if(empty($id)) return array();
    $LogsMod=new LogsMod();
    $ids=[$id];
    $category=Cache::read('category');
    if(!empty($category[$id]['children'])){
        $ids=array_merge($ids,$category[$id]['children']);
    }
    $logData=$LogsMod->cate($ids)->order($order)->limit($limit)->select();
    return $logData['list'];
}

Copy

Put this function in the template common.php In file , It can be called in the template , as follows ：

{foreach getLogsByCateId(1) as $k=>$v}
<a href="{$v['url']}">{$v['title']}</a>
{/foreach}

Copy

The first parameter is the classification to be obtained ID

The second parameter is the quantity obtained

The third parameter is sorting method
