在PHP中使用多个表单时，不会将插入值输入到数据库中

signup.php

signup.php

   <?php
  if (isset($_POST['signup'])) {
    $con = mysqli_connect("localhost", "root", "");
    mysqli_query($con, "CREATE DATABASE dream");
    mysqli_select_db($con, "dream");
    $counter = 1;
    $uname = $_POST['uname'];
    $uemail = $_POST['uemail'];
    $upass = $_POST['upass'];
    $gender = $_POST['gender'];
    $uage = $_POST['uage'];
    $ucourse = $_POST['ucourse'];
    $uclass = $_POST['uclass'];
    $ucontact = $_POST['ucontact'];
    $uaddress = $_POST['uaddress'];

    $ct = "CREATE TABLE student(sno INTEGER(3) NOT NULL AUTO_INCREMENT PRIMARY KEY, name VARCHAR(20), email VARCHAR(30), password VARCHAR(30), gender VARCHAR(30), age INTEGER(3), course VARCHAR(30), class VARCHAR(30), contact INTEGER(3), 
        address VARCHAR(100) )";
    mysqli_query($con, $ct);
    mysqli_query($con, "INSERT INTO student VALUES('$counter', '$uname','$uemail','$upass','$gender',
        '$uage','$ucourse','$uclass','$ucontact','$uaddress')");
    }

final.php

final.php

 <?php
    session_start();


    $_SESSION['ucourse'] = $_POST['ucourse'];
    $_SESSION['uclass'] = $_POST['uclass'];
    $_SESSION['ucontact'] = $_POST['ucontact'];
    $_SESSION['uaddress'] = $_POST['uaddress'];

    print_r($_POST);
    ?>

Here I've used two forms,
1. signup.php
2. signup2.php

在这里，我使用了两种形式，1。signup.php 2. signup2.php

Enter the data by using sessions of retrieve the data from form 1 to from 2 , The entered values are not inserted in database.

使用从表单1到2检索数据的会话输入数据，输入的值不会插入数据库中。

1 个解决方案

#1

is your final insert query in final.php? I think your action in signup2.php, will take you to dreams.php, not final.php Change this

是final.php中的最终插入查询？我认为你在signup2.php中的动作会带你去dreams.php，而不是final.php改变它

<form method = "post" action = "dreams.php">

to this

对此

<form method = "post" action = "final.php">

Btw, your final.php code, doesn't contain any sql insert query, add this to your final.php code

顺便说一下，你的final.php代码，不包含任何sql insert查询，将其添加到你的final.php代码中

mysqli_query($con, "INSERT INTO your_table VALUES($_SESSION['ucourse'], $_SESSION['uclass'],$_SESSION['ucontact'],$_SESSION['uaddress']");

Please modify the query to fit your table structure

请修改查询以适合您的表结构
