I'm using a prepared statement to SELECT *
from a MySQL table and I'm not sure how to use while($row = mysqli_fetch_array($stmt))
to loop through and select items from the result array. This is my code, what am I doing wrong?
$link = mysqli_connect($host, $username, $password, $db);
$query = "SELECT * from `wp_posts` WHERE ID=? ";
//$result = mysqli_query($link, $query);
$stmt = mysqli_prepare($link, $query);
if($stmt){
mysqli_stmt_bind_param($stmt, "i", $pid);
mysqli_stmt_bind_result($stmt, $dbpid);
mysqli_stmt_execute($stmt);
mysqli_stmt_fetch($stmt);
}
while($row = mysqli_fetch_array($stmt)){
?>
<h2 align="center"> <?php echo $row['post_title']; ?> </h2><br>
<div class="paracenter">
<p id="cont"><?php echo $row['post_content']; ?></p>
<hr color="black" width="10%">
</div>
<?php } ?>
Nothing wrong with Darwin's answer, but wanted to point out PDO as an alternative with much lighter syntax:
<?php
$options = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
$link = new PDO("mysql:host=$host;dbname=$db", $username, $password, $options);
$stmt = $link->prepare("SELECT * from `wp_posts` WHERE ID=?");
$stmt->execute([$pid]);
$result = $stmt->fetchAll();
// Now you have a plain array to work with, database work is over
foreach ($result as $row):
?>
<h2 style="text-align:center;margin:0 auto">
<?=$row["post_title"]?>
</h2>
<br/>
<div class="paracenter">
<p id="cont">
<?=$row["post_content"]?>
</p>
<hr style="color:black;width:10%"/>
</div>
<?php endforeach;?>
No need for any binding at all, and personally I find it much easier to work with.
