如何在PHP中使用預準備語句在多個表中插入數據？

Question

我有兩個表是billing_info, shipping_info。 billing_id是主鍵，billing_id是shipping_info中的外鍵。

我有billing_info地址表單。用戶將填寫結算信息，填寫信息後會出現一個複選框，稱爲shipping address is different。如果任何用戶選中該複選框，則它會詢問運輸信息。根據數據填寫運輸信息後，結算信息將存儲在billing_info表中，shipping_info將存儲在運輸信息表中。

如果用戶未選中複選框而不是隻有帳單信息將存儲在帳單信息表中。

<input type="checkbox" name="shipping_status" value="1"> 

我能夠插入到數據庫中的數據只針對billing_info如果用戶不選中複選框，但不能插入數據檢查後的複選框。 查詢可能有問題。我試過的查詢是

1) START TRANSACTION; 
    INSERT INTO table1 (column name)VALUES (values); 
    INSERT INTO table2 (column name) VALUES (values); 
    COMMIT; 

2) BEGIN; 
    INSERT INTO table1 (column name)VALUES (values); 
    INSERT INTO table2 (column name) VALUES (values); 
    COMMIT; 

但仍無法插入數據。 你能幫忙嗎？

這是存儲int用戶信息的正確方法嗎？

    $b_firstname=$conn->real_escape_string(trim($_POST['b_firstname']));

    $shipping_status=0; 
} 
else{

if ($shipping_status==0) {

} 


    $stmt->execute(); 
    $stmt->close(); 

    } 

//redirect code 
//header('Location: contactus.php'); 
    $conn->close(); 
} 

Answer 1

bind_params後，必須要插入計費信息，以便進行計費信息，如果語句不應該在插入查詢每次插入此

$firstname = "John"; 
$lastname = "Doe"; 
$email = "john@example.com"; 
$stmt->execute(); 

Answer 2

 if (empty($conn->real_escape_string(trim($_POST['shipping_status'])))) { 
     $shipping_status=0; 
$sql="INSERT INTO billing_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?)"; 
// print_r($sql); 
    $stmt = $conn->prepare($sql); 
    $stmt->bind_param("ssssssiiiis", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added); 

    } 
    else{ 
    $shipping_status=1; 
$sql="INSERT INTO billing_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?);INSERT INTO shipping_info (s_firstname, s_lastname, s_address, s_country, s_state, s_city, s_pincode, s_mobileno,b_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?);";

    }

默認情況下，。

$sql="INSERT INTO billing_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?)"; 
     // print_r($sql); 
      $stmt = $conn->prepare($sql); 
      $stmt->bind_param("ssssssiiiis", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added); 
     $stmt->execute(); 
    $stmt->close(); 

航運狀況選擇

if ($shipping_status==1) { 
     $sql="INSERT INTO shipping_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?)"; 
     // print_r($sql); 
      $stmt = $conn->prepare($sql); 
      $stmt->bind_param("ssssssiiiis", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added); 
$stmt->execute(); 
    $stmt->close(); 
     }
