仅在php codeigniter中标记某些属性时仅显示XML对象

Question 1

OK解决了此最终删除模型文件并将属性放在XML文件上：

<Videos>
    <video type="Module">
        <Title>TITLE</Title>
        <SubHeading>SUBHEADING</SubHeading>
        <url>YOUTUBECODE</url>
        <image>IMAGE.png</image>
        <description>DESCRIPTIOM</description>
        <link><![CDATA[<a href="/URL"><i class='fa-li fa fa-angle-double-right'></i>LINK</a>]]></link>
        <link2><![CDATA[<a href="/URL"><i class='fa-li fa fa-angle-double-right'></i>LINK</a>]]></link2>
    </video>
    <video type="Module" id="1">
        <Title>TITLE</Title>
        <SubHeading>SUBHEADING</SubHeading>
        <url>YOUTUBECODE</url>
        <image>IMAGE.png</image>
        <description>DESCRIPTIOM</description>
        <link><![CDATA[<a href="/URL"><i class='fa-li fa fa-angle-double-right'></i>LINK</a>]]></link>
        <link2><![CDATA[<a href="/URL"><i class='fa-li fa fa-angle-double-right'></i>LINK</a>]]></link2>
    </video>
    <video type="Common" id="1">
        <Title>TITLE</Title>
        <SubHeading>SUBHEADING</SubHeading>
        <url>YOUTUBECODE</url>
        <image>IMAGE.png</image>
        <description>DESCRIPTIOM</description>
        <link><![CDATA[<a href="/URL"><i class='fa-li fa fa-angle-double-right'></i>LINK</a>]]></link>
        <link2><![CDATA[<a href="/URL"><i class='fa-li fa fa-angle-double-right'></i>LINK</a>]]></link2>
    </video>
</Videos>

这使我能够在我想要的页面上显示单独的“视频”。使用：

<div class="col-sm-8 col-lg-9">
                    <?php if(file_exists('../application/libraries/VideoData.xml')) {
                        $xml = simplexml_load_file('../application/libraries/VideoData.xml');
                        $count = 0;
                        $counts = 0;
                        foreach($xml->children() as $child) {
                            $role = $child->attributes(); { 
                                if($role["1"])
                                    echo('<div class="media thumbnail software"><div class="' . (++$counts%2 ? "col-sm-5 text-center" : "col-sm-5 col-sm-push-7 text-center") . '">' . anchor('http://youtu.be/' . $child->url . '?autoplay=1', img("Thumbnails/" . $child->image,  $child->Title,  $child->Title, "media-object img-responsive img-thumbnail"), array('class' => 'fancybox-media')) . '</div><div class="media-body ' . (++$count%2 ? "col-sm-7" : "col-sm-7 col-sm-pull-5") . '"><h3 class="media-heading pageheading">'.anchor('http://youtu.be/' . $child->url . '?autoplay=1', $child->Title . '<br /><small>' . $child->SubHeading . '</small>', array('class' => 'fancybox-media')) . '</h3><hr class="heading"><p>'. $child->description .'</p><ul class="fa-ul"><li>' . $child->link .'</li></ul></div></div>');
                            }
                        }
                    } ?>
                </div>

或者：

<div class="col-sm-8 col-lg-9">
                    <?php if(file_exists('../application/libraries/VideoData.xml')) {
                        $xml = simplexml_load_file('../application/libraries/VideoData.xml');
                        $count = 0;
                        $counts = 0;
                        foreach($xml->children() as $child) {
                            $role = $child->attributes(); { 
                                if($role == "Module")
                                    echo('<div class="media thumbnail software"><div class="' . (++$counts%2 ? "col-sm-5 text-center" : "col-sm-5 col-sm-push-7 text-center") . '">' . anchor('http://youtu.be/' . $child->url . '?autoplay=1', img("Thumbnails/" . $child->image,  $child->Title,  $child->Title, "media-object img-responsive img-thumbnail"), array('class' => 'fancybox-media')) . '</div><div class="media-body ' . (++$count%2 ? "col-sm-7" : "col-sm-7 col-sm-pull-5") . '"><h3 class="media-heading pageheading">'.anchor('http://youtu.be/' . $child->url . '?autoplay=1', $child->Title . '<br /><small>' . $child->SubHeading . '</small>', array('class' => 'fancybox-media')) . '</h3><hr class="heading"><p>'. $child->description .'</p><ul class="fa-ul"><li>' . $child->link2 .'</li></ul></div></div>');
                            }
                        }
                    } ?>
                </div>

取决于我想显示的内容。感谢Kurn的帮助，因为它使我研究了各种能够实现这一目标的方法，并最终使用以下方式：

帮助我。希望这对其他人有帮助:)

Question 2

我不知道您如何使用视图/模型处理整个情况。但是，有了实际的体系结构，您将无法获得希望的结果。

我现在制作了一个快速而肮脏的版本，我将如何实现。

public function catalog($category_id = 1)
{
    $data = array();

    //$path = '../application/libraries/VideoData.xml';
    $path = '1.xml';
    $xml = simplexml_load_file($path);
    $json = json_encode($xml);
    $array = json_decode($json, TRUE);

    foreach ($array['video'] as $video)
    {
        if ($video['category'] == $category_id)
        {
            $data[] = $video;
        }
    }

    return $data;
}

当然，您可以使用原始的Calatog方法，并使用新方法仅获取通缉视频。

这样，您可以通过URL参数将类别拨打控制器，仅将过滤结果返回到视图
