CodeIgniter功能没有显示？

Question

helper.website.php

public function load_top_players() { 
    $this->load->lib(array('rank_db', 'db'), array(HOST, USER, PASS,CHARACTERS));
    $query = $this->rank_db->query('SELECT name, access FROM users ORDER BY access DESC LIMIT 5');
    while($row = $query->fetch()) {
        $this->rank[] = array(
            'name'  => htmlspecialchars($row['name']),
            'level' => (int)$row['access']
        );
    }
    return $this->rank;
}

view.header.php

<?php
$rank = load::get('website');
$i = 1;
foreach ($rank as $pos => $player) {
    $first = (in_array($i, array(1))) ? '' : '';
    $second = (in_array($i, array(2))) ? '' : '';
    echo '<tr style="'.$first.' '.$second.' '.$third.'">
        <td  >'.$i.'</td>
        <td>'.$player['name'].'</td>
        <td>'.$player['access'].'</td>
    </tr>';
    $i++;
}
?>

它显示一个空白页面，没有任何错误！

<强> helper.website.php

public function getOnlineCount(){
        $this->load->lib(array('rank_db', 'db'), array(HOST, USER, PASS, CHARACTERS));  
        return $this->registry->rank_db->snumrows('SELECT count(name) as count from users where status <> -1 AND sub_status>= 1');
    }

并在 view.header.php <?php echo load::get('website')->getOnlineCount() ; ?>中完美无缺！如何将其转换为我的查询

它显示空白页面，因为您没有将任何数据传递到您的视图文件。要在视图文件中获取数据，必须使用某些数据从控制器加载视图。语法是 -

CC=gcc

 CFLAGS=-I

AIM = server

HEADS = ../common/common.h

OBJS = comfunc.o

MOBJ = server.o

MISCS = server.cfg

SRCS = ${OBJS:.o=.c} ${MOBJ:.o=.c}

#targets
all: $(AIM)


server:server.o $(OBJS) $(MOBJ)

        $(CC) $(LDFLAGS) $(CFLAGS) -o server server.o $(OBJS) $(LIBS)

#dependency
$(OBJS):../common/common.h

comfunc.o: ../common/common.h

然后从您的视图文件中访问它。
