php - SQL 从页面 ID 中选择行

Question

我正在尝试填充使用（ port_id=$project ）创建的页面。单个帖子页面有效，并且正在填充，但由整个表而不是仅具有相同 ID 的行填充。这是我的单页代码：

$db = dbconnect('test');
$sql = 'SELECT * FROM portfolio'; 
$result = $db->query($sql) or die(mysqli_error());
$currportfolio = $_GET['port_id'];

while($row = $result->fetch_assoc()){
$project = $row['port_id'];
echo "
<div class='post-img bottom-50'>
<h3 class='bottom-20'><a href='blog-single.html'>Consectetur adipisicing elit</a></h3>
<div class='proj-img1 bottom-20'>             
<a class='prettyPhoto zoom' href='upload/".$row['image']. "'>
<img src='images/content/portimg.jpg' alt=''></a>
</div>
<p>".$row['description'] . "</p>
</div>
</div>
";}

Answer 1

You should could call the $currportfolio variable first, and then add it into the query

$sql = 'SELECT * FROM portfolio WHERE port_id = $currportfolio ';

Then you are only calling the values from that specific row.
