Question

我正在制作一个包含我上传到数据库的每个视频的页面。

按日期过滤，按日期排序。每个带JavaScript的视频都有一个onclick。它必须在网站上显示所有价值。

但是当我点击视频时，它必须使用他们拥有的标签过滤所有视频。它现在唯一能做的就是，当我想过滤它时，它会显示带有视频的正确标签，但不会显示正确的标签。然后它会从我首先发布的视频中提供标签。

点击后如何获得正确的标记值？当我想过滤标签？

<?php

$query = $connectie->prepare("SELECT v.VideoID,v.Titel,v.Link,v.Omschrijving,o.Bestandspath, o.Bestandsnaam,o.Onderwerp,t.Naam, DATE_FORMAT(`postDate`,\"%e-%m-%Y %H:%i\")as tijd FROM video v join opdracht o on v.OpdrachtID = o.OpdrachtID JOIN videotag vt on v.VideoID = vt.VideoID
JOIN tag t on vt.TagID = t.TagID order by `postDate` ");
$query->execute();

while ($row = $query->fetch(PDO::FETCH_ASSOC)) {

    $link = $row['Link'];
    $newLink = str_replace("watch?v=", "embed/", $link);
    $data = file_get_contents('https://www.youtube.com/oembed?format=json&url=' . $link);
    // echo $newLink;
    $json = json_decode($data);
    $thumbnail = $json->thumbnail_url;
    $title = $json->title;
    $onderwerp = $row['Onderwerp'];
    $omschrijving = $row['Omschrijving'];
    $filePath = $row['Bestandspath'];
    $bestandsnaam = $row['Bestandsnaam'];
    $videoid = $row['VideoID'];
    $tagName = $row['Naam'];
    echo 'tagname',$tagName;

    echo
    '

                <p id="titelText"><b>' . htmlentities($title) . '</b></p>
            </a>
        </div>

        <script>
            function getLink(link,titel,onderwerp,tagNaam,omschrijving,bestandsnaam,bestandspath){
                document.getElementById("videoFrame").src = link;
                document.getElementById("videoFrame").style.display = "block";
                document.getElementById("overzicht").style.width = "275px";

                document.getElementById("titelVideo").innerHTML = "<b>Titel</b>:"+titel+"<br>";
                document.getElementById("onderwerp").innerHTML = "<b>Onderwerp</b>:"+onderwerp+"<br>";

                document.getElementById("bestand").href = bestandspath;
