Question

$sql = "SELECT * from post where forum_id = $_GET[id]";
    $result = mysqli_query($conn, $sql) or die('Error querying database.');     
    while ($row = mysqli_fetch_array($result)) {
        echo '' . $row['fourm_id']; 
        echo '<div id="post3">
            <p class="1">
            <span class="name">'.'
            ' .$row['name']. '</span>'.
            '<span class="trip">
            ' .' !'
            . $row['title'].''.
            ' </span>'.
            ' <span class="time">
            ' .$row['time']. '' . 
            ' </span>'.
            ' </p>
            <p class="2">
            <span class="texts">
            ' .$row['texts']. '' .
            ' </span>'.
            ' </p>'.
            if (!isset($_SESSION["user_id"])) { 
            }
             else {
             '<a href="delete_post.php?fourm_id=' . $row['id']. '>Delete</a>' . }
            ' </div>';
         } 
        mysqli_close($conn);

?>

The mistake in the code is obvious, just showing what I am trying to do.

This echo I have here displays the users post, how would I go about sticking an isset in there so only admins can see the delete link? Or is there another way of doing it outside the echo with out it going outside the user post?

<?
$data = array();
$sql  = "SELECT * from post where forum_id = ".intval($_GET['id']);
$res  = mysqli_query($conn, $sql) or trigger_error(mysqli_error($conn));
while ($row = mysqli_fetch_array($result)) {
  $data[] = $row;
}
?>
<?php foreach($data as $row): ?>
<?=$row['fourm_id']?>
<div id="post3">
  <p class="1">
    <span class="name"><?=$row['name']?></span>
    <span class="trip"> !<?=$row['title']?></span>
    <span class="time"><?=$row['time']?></span>
  </p>
  <p class="2">
    <span class="texts"><?=$row['texts']?></span>
  </p>
<?     if (isset($_SESSION["user_id"])): ?>
  <a href="delete_post.php?fourm_id=<?=$row['id']?>">Delete</a>
<?     endif ?>
</div>
<? endforeach ?>
