打开手风琴时，请通过该文章的ID获取网址

I want to display the article ID in my URL when i press the a href in code beneath

Update, i included the php section and the while loop with the article ID

require_once("inc/connection.php");
mysql_select_db("nieuws");
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$id = $_GET['id'];
$datum = $_POST["datum"];
$titel = $_POST["titel"];
$artikel = $_POST["artikel"];
$checkbox = $_POST["checkbox"];
$titel = mysql_real_escape_string(nl2br(htmlentities($_POST["titel"])));
$artikel = mysql_real_escape_string($_POST["artikel"]);
$id = mysql_real_escape_string($_POST['id']);
date_default_timezone_set('GMT');
$datum = date('Y-m-d', strtotime(str_replace('-', '/', $datum)));
    if(isset($_POST['add'])){
        if(!empty($_POST['titel']) && !empty($_POST['artikel']) && !empty($_POST['datum'])){
        $query="INSERT INTO nieuws (id,datum,titel,artikel) VALUES ('$id','$datum','$titel','$artikel')";
        $datum = date('Y-m-d', strtotime(str_replace('-', '/', $datum)));
        str_replace('<br />', "
", $textarea);
        $result=mysql_query($query);
        $juist1 = true;
        }else{
        $fout1 = true;
        }
    }if(isset($_POST['delete'])){
        foreach($_POST['checkbox'] as $del_id){
        $sql="DELETE FROM nieuws WHERE id='$del_id'";
        $result = mysql_query($sql);
        $juist2 = true;
        }
        }
}

This is the accordion script that opens on click

$('.acc_container').hide(); //Hide/close all containers
$('.acc_trigger').click(function(){
if( $(this).next().is(':hidden') ) { //If immediate next container is closed...
    $('.acc_trigger').removeClass('active').next().slideUp();
    $(this).toggleClass('active').next().slideDown();
}
return false;
});
});

This is the FORM part

<form method="POST" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>">
<table style="width:950px; margin-bottom:5px;">
<tr>
<td>Datum:<br />
<input type="text" name="datum" size="20" style="width:100px;" value="<?php echo $datum;   ?>" id="datepicker" placeholder="Kies datum"/><br /></td>
<td>Titel:<br />
<input type="text" name="titel" size="200" style="width:500px;" maxlength="45" value="<? php echo $titel; ?>" placeholder="Max. 50 characters toegelaten"/><br /></td>         </tr>
</table>            
Artikel: <br />
<textarea id="textarea" name="artikel" style="width:500px; height:150px;" value="<?php  echo $artikel; ?>" ></textarea><br />

<input type="submit" name="add" value="Artikel toevoegen" />
</form>

This is the while loop where i ADD the row ID

$query="SELECT id,datum,titel,artikel FROM nieuws ORDER BY id DESC";
$result=mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)){
echo ("<div id=\"artikeltitel\" align=\"center\">
    <div id=\"containerdatum\">".$row['datum']."</div>
    <div id=\"containertitel\">".$row['titel']."</div>
    <div id=\"container3\" style=\"font-size:12px;\">".$row['id']."
    <input type=\"checkbox\" name=\"checkbox[]\" id=\"checkbox\"   value=\"".$row['id']."\"       />
    </div>
    </div>
    <div class=\"container\" align=\"center\">
    <h2 class=\"acc_trigger\"><a href=".$row['id']."> &#187; </a></h2>
    <div class=\"acc_container\">
    <div class=\"block\">".$row['artikel']."</div>
    <div class=\"fb-comments\" data-href=\"http://www.zpb-polonez.be/user.php\" data-num-    posts=\"10\" data-width=\"678\" style=\"margin-top:2px;\"></div>
    </div>
    </div>
    ");
}

I don't know what to add more to explain what i'm trying to achive

We lack some information here to be able to help but let's try anyway.

Let's assume that your article id is $row['id'] you could build your link this way:

echo '<a href="#' . $row['id'] . '">Link</a>';
