如何在pdo中添加多列以进行更新？这是我想要做的，但我需要更新多个 $ _ POSTS [＆＃39; VARS];

$consulta = $conexao_pdo->prepare('UPDATE user SET nome = ? WHERE id = ?');
$consulta->bindParam(1, $variavel_com_nome);
$consulta->bindParam(2, $id);
if ($consulta->execute()) {
  echo 'UPDATED';
}

Answer 1

什么是代码中无效？如果需要更新多个列，只需将它们包含在更新语句中：update table1 set col1 = ?, col2 = ?, col3 =？其中id =？;然后为每一个分配参数值。

这就是我解决它的方式

$sql = "UPDATE user SET name = :name, 
            surname = :surname
            WHERE username = :username";

            //db column and value
$stmt = $conexao_pdo->prepare($sql);  
//where clause                                 
$stmt->bindParam(':username', $username);  
//add vars to db      
$stmt->bindParam(':name', $var);    
$stmt->bindParam(':surname', $var);

$stmt->execute();

使用PDO更新多列
