php - 如何通过单击要编辑的项目来编辑 SQL 数据

Question

所以我有一个从 SQL 数据生成的表，我希望能够从表中编辑该数据，而无需转到单独的表单。我希望用户能够选择表格的任何部分并进行更改。这是可能的还是必须使用单独的表格来完成？目前我有这个只显示表格：

<?php
$con=mysqli_connect("localhost","root","","db_test");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
$result = mysqli_query($con,"SELECT * FROM tbl_products");

echo "<table border='1'>
<tr>
<th>Products:</th>
<th>Price:</th>
</tr>";

while($row = mysqli_fetch_array($result))
  {
  echo "<tr>";
  echo "<td><a href=\"product.php?id=". $row['product_id'] ."\">" . $row['product_name'] . "</a></td>";
  echo "<td>" . $row['product_price'] . "</td>";
  echo "</tr>";
  }
echo "</table>";

mysqli_close($con);
?>
