Question

我一直试图找出允许在我的代码中进行搜索和最重要的删除数据的神奇代码。我把所有的搜索代码放在一起，它的效果很好，但是当它被删除时，我遇到了困难，我找不到合适的地方和代码来删除我的数据。我看到谷歌里发现的无处不在。我的问题是，任何人都可以解决这个删除问题，或者目前的技术是不可能的？我的代码如下所示：

<?php 
//load database connection
    $host = "localhost";
    $user = "abcd";
    $password = "******";
    $database_name = "abcd";
    $pdo = new PDO("mysql:host=$host;dbname=$database_name", $user, $password, array(
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
    ));
// Search from MySQL database table




$search=$_POST['search'];
$query = $pdo->prepare("select * from wfuk where post_code LIKE '%$search%' OR telephone LIKE '%$search%'  LIMIT 0 , 10");
$query->bindValue(1, "%$search%", PDO::PARAM_STR);
$query->execute();
// Display search result
?>

    echo "<tr>

   while ($results = $query->fetch()) {

    echo "<tr><td style=\"border-style:solid;border-width:1px;border-color:#98bf21;\">";            
    echo $results['first_name'];

    echo "</td><td style=\"border-style:solid;border-width:1px;border-color:#98bf21;\">";           
    echo $results['last_name'];

    echo "</td><td style=\"border-style:solid;border-width:1px;border-color:#98bf21;\">";           
    echo $results['trade'];

    echo "</td><td style=\"border-style:solid;border-width:1px;border-color:#98bf21;\">";           
    echo $results['post_code'];

    echo "</td><td style=\"border-style:solid;border-width:1px;border-color:#98bf21;\">";
    echo $results['telephone'];

    echo "</td><td style=\"border-style:solid;border-width:1px;border-color:#98bf21;\">";
    echo $results['comments'];

    echo "</td><td style=\"border-style:solid;border-width:1px;border-color:#98bf21;\">";
    echo("<button onclick=\"location.href='search.php?del=" . $results['id'] . "'\"> delete user</button>"); 

    echo "</td></tr>";              
     }
    echo "</table>";        
     } else {
    echo 'Nothing found';
     }
?>

Answer 1

您需要的查询：

DELETE FROM wfuk 
WHERE id = ?

id参数的值将是查询字符串：

$query->bindValue(1, $_GET['del'], PDO::PARAM_INT);

Answer 2

你好删除选项必须在删除页面上完成

class Foo {
  def boo(a: String, b: String): Unit = ()
  def boo(a: String, b: Int): Unit = boo(a, b.toString)
}

使用pdo在一个页面中搜索后从sql中删除数据
