从一组变量 post 到多个 Php 数据库表

Question

我的数据库 table.

中有一个 HTML 表格的变量，目前正在 post 编辑为一个 table

我想 post 在同一个函数中同时将这些相同的变量 table 传递给其他 table 。这可能吗？这是我当前的 PHP 函数，它 post 成功转换为一个 table

<?php
    $var1 = $_POST['var1'];
    $var2 = $_POST['var2'];
    $var3 = $_POST['var3'];


    // Database connection
    $conn = new mysqli('localhost','user','password','database');
    if($conn->connect_error){
        echo "$conn->connect_error";
        die("Connection Failed : ". $conn->connect_error);
    } else {
        $stmt = $conn->prepare("insert into table1(var1, var2, var3) values(?, ?, ?)");
        $stmt->bind_param("sss", $var1, $var2, $var3);   
        $execval = $stmt->execute();
        echo $execval;
        $stmt->close();
        $conn->close();
    }
?>

而且我想在同一个数据库中将以下变量 post 转换为多个 table，所以考虑了以下但它不起作用 -

<?php
    $var1 = $_POST['var1'];
    $var2 = $_POST['var2'];
    $var3 = $_POST['var3'];


    // Database connection
    $conn = new mysqli('localhost','user','password','database');
    if($conn->connect_error){
        echo "$conn->connect_error";
        die("Connection Failed : ". $conn->connect_error);
    } else {
        $stmt = $conn->prepare("insert into table1(var1, var2, var3) values(?, ?, ?)");
        $stmt->bind_param("sss", $var1, $var2, $var3);
        $stmt = $conn->prepare("insert into table2(var1) values(?)");
        $stmt->bind_param("s", $var1);
        $stmt = $conn->prepare("insert into table3(var2, var3) values(?, ?)");
        $stmt->bind_param("ss", $var2, $var3); 
        $execval = $stmt->execute();
        echo $execval;
        $stmt->close();
        $conn->close();
    }
?>

Answer 1

尝试调用$stmt->execute();每次调用 $stmt->bind_param();

之后

看看这个已解决的问题，在同一个调用中执行多个查询。 PDO support for multiple queries (PDO_MYSQL, PDO_MYSQLND)

Answer 2

是的，这是可能的。你可以做你现在正在做的事情，但你需要在准备好每个查询后调用 execute() 方法。除此之外，将其包装在交易中也是一个好主意。事务可帮助您确保所有或 none 操作都成功。如果其中之一失败，则不会执行其他操作。

您的固定代码应如下所示：

<?php
$var1 = $_POST['var1'];
$var2 = $_POST['var2'];
$var3 = $_POST['var3'];


// Database connection
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); // switches error reporting on
$conn = new mysqli('localhost','user','password','database');
$conn->set_charset('utf8mb4'); // always set the charset

// Start transaction
$conn->begin_transaction();

$stmt = $conn->prepare("insert into table1(var1, var2, var3) values(?, ?, ?)");
$stmt->bind_param("sss", $var1, $var2, $var3);
$stmt->execute();

$stmt = $conn->prepare("insert into table2(var1) values(?)");
$stmt->bind_param("s", $var1);
$stmt->execute();

$stmt = $conn->prepare("insert into table3(var2, var3) values(?, ?)");
$stmt->bind_param("ss", $var2, $var3); 
$stmt->execute();

// End transaction
$conn->commit();
