帝国高效率随机调用功能扩展

知识点总结
1.PHP代码

function ZQrand($classid , $num){
    global $dbtbpre,$empire;
    /* 检测json文件是否存在 */
    $file_arrs = glob(ECMS_PATH."d/json/*.json");
    $file_cache = $file_arrs[0];
    //缓存整个news表的数据
    if(!file_exists($file_cache) || time()-@filemtime($file_cache)>86400){
        //创建文件夹
        @mkdir(ECMS_PATH."d/json/",0777);
        //查询分类
        $hm_class=$empire->query("select classid from {$dbtbpre}enewsclass"); 
        while($hm_r=$empire->fetch($hm_class))
        {
            //查询分类下面的所有id
            $hm_news=$empire->query("SELECT id FROM `{$dbtbpre}ecms_news` WHERE `classid` = {$hm_r[classid]}"); 
            while($hm_nr=$empire->fetch($hm_news))
            {
                $news_data[] = $hm_nr[id];
                $all_id[] = $hm_nr[id];
            }
            file_put_contents(ECMS_PATH . "d/json/" . $hm_r['classid'] . ".json",json_encode($news_data));
            unset($news_data);
        }
        file_put_contents(ECMS_PATH . "d/json/" . allId . ".json",json_encode($all_id));
    }
    $num = (int) empty($num)?10:$num;
    $classid = (int)$classid;
   // 获取所有的文件
    $hm_class=$empire->fetch1("select classid from {$dbtbpre}enewsclass where classid = {$classid}"); 
    if(empty($hm_class[classid])){
        // 随机调用
        $file_arrs = json_decode(file_get_contents(ECMS_PATH."d/json/allId.json"),true);
    }else{
        //调用栏目
        $file_arrs = json_decode(file_get_contents(ECMS_PATH."d/json/{$classid}.json"),true);
        if(empty($file_arrs)){
            $file_arrs = json_decode(file_get_contents(ECMS_PATH."d/json/allId.json"),true);
        }
    }
    if(empty($file_arrs)){
        return '';
    }else{
        for ($rani=1; $rani<=$num; $rani++){
            $rand_id.= $file_arrs[mt_rand(0,count($file_arrs)-1)].",";    
        }
        $rand_id = rtrim($rand_id,",");
        $where = "id in ($rand_id)";
        return $where;
    }
}

2.js代码,主要用于关闭弹窗，定时的

setTimeout(function(){
    window.close();
    document.onload = window.close();
},1000);

2022.8.19 代码改进：

function ZQrand($classid , $num = 100){
    global $dbtbpre,$empire;
    ZQcread();
    $num = (int) $num*3;
    $classid = (int)$classid;
   // 获取所有的文件
    $hm_class=$empire->fetch1("select classid from {$dbtbpre}enewsclass where classid = {$classid} and `bclassid` != 0"); 
    if(empty($hm_class[classid])){
        // 随机调用
        $file_arrs = json_decode(file_get_contents(ECMS_PATH."d/json/allId.json"),true);
    }else{
        //调用栏目
        $file_arrs = json_decode(file_get_contents(ECMS_PATH."d/json/classId.json"),true);
        $file_arrs = $file_arrs[$classid];
    }
    if(empty($file_arrs)){
        return '';
    }else{
        for ($rani=0; $rani<$num; $rani++){
            $rand_id.= $file_arrs[mt_rand(0,count($file_arrs)-1)].",";    
        }
        $rand_id = rtrim($rand_id,",");
        $where = "id in ($rand_id)";
        return $where;
    }
}

function ZQcread(){//创建缓存文件
    global $dbtbpre,$empire;
    /* 检测json文件是否存在 */
    $class_cache = ECMS_PATH."d/json/classId.json";
    $all_cache =  ECMS_PATH."d/json/allId.json";
    //缓存整个news表的数据
    // time()-@filemtime($file_cache)>86400
    if(!file_exists($class_cache) || !file_exists($all_cache)){
        //创建文件夹
        @mkdir(ECMS_PATH."d/json/",0777);
        //查询分类
        $hm_class=$empire->query("select classid from {$dbtbpre}enewsclass"); 
        while($hm_r=$empire->fetch($hm_class))
        {
            //查询分类下面的所有id
            $hm_news=$empire->query("SELECT id FROM `{$dbtbpre}ecms_news` WHERE `classid` = {$hm_r[classid]}"); 
            while($hm_nr=$empire->fetch($hm_news))
            {
                $class_data[$hm_r['classid']][] = $hm_nr[id];
                $all_data[] = $hm_nr[id];
            }
        }
        file_put_contents($class_cache,json_encode($class_data));
        file_put_contents($all_cache,json_encode($all_data));
    }
}

客户反馈高效率调用会出现bug，经过查证发现，主要是num参数限制了，已改进

10.5 根据自己的需求修改，备份于此

function ZQrand($classid , $num = 60){
    global $dbtbpre,$empire;
    /* 检测json文件是否存在 */
    $file_arrs = glob(ECMS_PATH."d/json/*.json");
    $file_cache = $file_arrs[0];
    //缓存整个news表的数据
    if(!file_exists($file_cache)){
        //创建文件夹
        @mkdir(ECMS_PATH."d/json/",0777);
        //查询分类
        $hm_class=$empire->query("select classid from {$dbtbpre}enewsclass"); 
        while($hm_r=$empire->fetch($hm_class))
        {
            //查询分类下面的所有id
            $hm_news=$empire->query("SELECT id FROM `{$dbtbpre}ecms_news` WHERE `classid` = {$hm_r[classid]}"); 
            while($hm_nr=$empire->fetch($hm_news))
            {
                $news_data[] = $hm_nr[id];
            }
            file_put_contents(ECMS_PATH . "d/json/" . $hm_r['classid'] . ".json",json_encode($news_data));
            unset($news_data);

        $more = 0;

                unset($all_id);
                $more = 0;
            }
            $more++;
        }
        
    }
    $num = (int) empty($num)?10:$num;

   // 获取所有的文件
    $hm_class=$empire->fetch1("select classid from {$dbtbpre}enewsclass where classid = {$classid} and bclassid != 0"); 
    if(empty($hm_class[classid])){
        // 随机调用
        $file_arrs = glob(ECMS_PATH."d/json/allId*.json");
        $counts = count(glob(ECMS_PATH."d/json/allId*.json")) - 1;
        // print_r($file_arrs);
