Question

我正在努力掌握PHP中多查询的概念，并且必须做错事但我不确定是什么。我将数据存储在来自其他表单的会话中。

<?php 
    $conn=mysql_connect("database","username","password");
    mysql_select_db("host",$conn);

    session_start();

    $insert_query=("INSERT INTO testone_tbl 
                      (age,hours,flexibility,fastpaced,retailexp,workedus,conviction,permit,education)
                    VALUES 
                      ('$age','$hours','$flexibility','$fastpaced','$retailexp','$workedus','$conviction,'$permit','$education') 
                    INSERT INTO equality_tbl 
                      (age,ethnic,disability)
                    VALUES ('$age','$ethnic'.'$disability')");

    mysql_multiquery($insert_query);
?>

还有更多的表要插入，但不想用不必要的重复来“敲打”问题。如果有人能够解释我做错了什么，那么非常感谢，提前谢谢。

Answer 1

要使多个查询起作用，所有查询必须用分号;分隔，因此在您的情况下：

$insert_query = "
    INSERT INTO testone_tbl (age,hours,flexibility,fastpaced,retailexp,
    workedus,conviction,permit,education)
    VALUES ('$age','$hours','$flexibility','$fastpaced','$retailexp','$workedus',
    '$conviction,'$permit','$education'); <--Semicolon
    INSERT INTO equality_tbl 
    (age,ethnic,disability)
    VALUES ('$age','$ethnic'.'$disability')";

Answer 2

试试这个，删除括号并在查询之间添加分号

$insert_query="
    INSERT INTO testone_tbl (age,hours,flexibility,fastpaced,retailexp,
    workedus,conviction,permit,education)
    VALUES ('$age','$hours','$flexibility','$fastpaced','$retailexp','$workedus',
    '$conviction,'$permit','$education');
    INSERT INTO equality_tbl 
    (age,ethnic,disability)
    VALUES ('$age','$ethnic'.'$disability');";

没有mysql_multiquery()这样的东西，这就是它返回的原因：

致命错误：在...上调用未定义的函数mysql_multiquery（）

函数mysql_multiquery()未定义，这意味着它不存在。

相反，使用mysqli_multi_query，但是你必须使用更安全的mysql i 方法。还要尝试使用分号（;）来结束查询。

// Create mysqli connection
$conn = mysqli_connect("server", "user", "password", "database");

$query  = "INSERT INTO testone_tbl 
             (age,hours,flexibility,fastpaced,retailexp,workedus,conviction,permit,education)
           VALUES 
             ('$age','$hours','$flexibility','$fastpaced','$retailexp','$workedus','$conviction,'$permit','$education');";
$query .= "INSERT INTO equality_tbl 
             (age,ethnic,disability)
           VALUES 
             ('$age','$ethnic'.'$disability');";

// Execute queries
if(mysqli_multi_query($conn, $query)) 
    echo "Success!";
else
    echo "Error";

将数据插入多个表
