Question

我需要做的是将top5变量数组用于我的索引页面。截至目前，它说它是一个未定义的变量。因此，使用if语句分配页面变量时，它需要知道如何发送top5变量数组，如果它将加载它的索引页面。当我在控制器中执行top5变量的print_r时，它会显示如下：

Array ( [0] => Array ( [character_name] => Kid Wonder ) [1] => Array ( [character_name] => Ryu Satoshi ) [2] => Array ( [character_name] => Oriel ) [3] => Array ( [character_name] => "The Ladies Man" Luscious Landon ) [4] => Array ( [character_name] => "The Outlaw" Mike Mayhem ) )

控制器：

$siteInfo = $this->site->getSiteTitleAndSlogan();
$activeTemplate = $this->site->getTemplate();
if ($this->site->pageStatus('index', $activeTemplate[0]->id) == 1){
    $page = $this->load->view($activeTemplate[0]->short_name.'/pages/index', '', true); 
} else {
    $page = $this->load->view($activeTemplate[0]->short_name.'/pages/404', '', true); 
}
$footerLinks = $this->site->getFooterNav(); 
$top5 = $this->site->getTop5(); 
print_r($top5);
$this->template
->title($siteInfo[0]->site_name,$siteInfo[0]->site_slogan)
->prepend_metadata('<link rel="stylesheet" type="text/css" href="http://www.kansasoutlawwrestling.com/assets/css/'.$activeTemplate[0]->short_name.'.css" />')
->set('footerLinks', $footerLinks)
->set('page', $page)
->set('top5', $top5)               
->set_partial('header', $activeTemplate[0]->short_name.'/header')
->set_partial('navigation', $activeTemplate[0]->short_name.'/navigation')            
->set_partial('content', $activeTemplate[0]->short_name.'/content')
->set_partial('footer', $activeTemplate[0]->short_name.'/footer')
->build('kow');

        ->set_partial('footer', $activeTemplate[0]->short_name.'/footer')
        ->build('kow');

查看：

<?php

for($i=0;$i < count($toprankings); $i++) 
{
   echo "character_name: ".$toprankings[$i]['character_name']."<br>";

}

?>

Answer 1

您的for循环是向后的。

for ($i = 0; $i >= count($top5); $i++){

应该是

for($i=0;$i<count($top5);$i++)

$i从0开始，因此永远不会超过count，即使它相等也不会增加或迭代。

尝试删除视图中除top5部分之外的所有内容，并将其更改为：

<?php 
    for($i=0;$i<count($top5);$i++)
    {
        foreach($top5[$i] as $k=>$v)
        {
        echo $k."   =    ".$v."<BR>";
        }
    }
?>

只是为了看它是否有效。此外，它有助于了解您正在使用的模板系统。

变量没有通过
