调用其他php时无法在mysql表中插入

php

调用其他php时无法在mysql表中插入,php,mysqli,Php,Mysqli,当我按下crudindex.php中的register按钮时，它会将数据插入到cruduser（表）中一旦完成，调用crudad.php并将数据插入crud（表），其中max（id）作为id来自cruduser表问题是：一旦我按下寄存器按钮，Cruduser（表）就会正确插入。但在crud（表）中，它只插入id，其他字段为空。我怀疑这篇文章没有选择值或插入一些问题但当我给出静态值时，例如：firstname作为'Tim'，lastname作为'cook'等等，它将插入表crud中另外

当我按下crudindex.php中的register按钮时，它会将数据插入到cruduser（表）中一旦完成，调用crudad.php并将数据插入crud（表），其中max（id）作为id来自cruduser表

问题是：一旦我按下寄存器按钮，Cruduser（表）就会正确插入。但在crud（表）中，它只插入id，其他字段为空。我怀疑这篇文章没有选择值或插入一些问题

但当我给出静态值时，例如：firstname作为'Tim'，lastname作为'cook'等等，它将插入表crud中

另外，当我单独运行crudad.php时，它会正确插入

结构：

cruduser(
  id(int),
  username(varchar),
  password(varchar)
)

crud(
  id(int),
  firstname(varchar),
  lastname(varchar),
  email(varchar),
  gender(varchar),
  age(varchar)
)

使用：表：cruduser和crud php:crudindex.php和crudad.php

<?php
//session_start();
//$maxiid = $_SESSION['id'];
//echo $maxiid;

$con = mysqli_connect("127.0.0.1", "kkits996_ganesh", "mysql123#", "kkits996_testmysql")  or die("Error " . mysqli_error($con));
$result = mysqli_query($con,"SELECT * FROM cruduser WHERE id=(SELECT MAX(id) FROM cruduser)");
$row1 = mysqli_fetch_array($result);
$c1 = $row1['id'];
mysqli_close($con);

$con = mysqli_connect("127.0.0.1", "kkits996_ganesh", "mysql123#", "kkits996_testmysql")  or die("Error " . mysqli_error($con));
if (isset($_POST) && (!empty($_POST))){
 $fname=mysqli_real_escape_string($con,$_POST["fname"]);
 $lname=mysqli_real_escape_string($con,$_POST["lname"]);
 $email=mysqli_real_escape_string($con,$_POST["email"]);
 $gender=$_POST["gender"];
 $age=$_POST["age"];

print "I am here";
echo $finame;
echo $liname;
print email;
//Notes : In Insert if numeric do not use quotes. if string use quotes.for auto use ''
$createsql="INSERT INTO crud(id,firstname,lastname,email,gender,age) VALUES
                         ($c1,'$fname','$lname','$email','$gender','$age')";

if (mysqli_query($con,$createsql)) {
echo "Connection Successful";
}
else
{
echo "Connection Issue";
die(mysqli_error($con));
}
mysqli_close($con);
}
?>

核心问题：数据未正确插入crud表

Crudindex.php

<?php
$con = mysqli_connect("127.0.0.1", "kkits996_ganesh", "mysql123#", "kkits996_testmysql")  or die("Error " . mysqli_error($con));
if (isset($_POST) && (!empty($_POST))){
 $uname=mysqli_real_escape_string($con,$_POST["uname"]);
 $pwd=mysqli_real_escape_string($con,$_POST["pwd"]);
 $cpwd=mysqli_real_escape_string($con,$_POST["cpwd"]);
if (isset($_POST['register'])) {
        # Register-button was clicked
$createsql1="INSERT INTO cruduser(id,username,password) VALUES
                             ('','$uname','$pwd')";

if (mysqli_query($con,$createsql1)) {
echo "Insert Successful in Table cruduser";
mysqli_close($con);
include ("crudadd.php");
}
else
{
die(mysqli_error($con));
}
}
mysqli_close($con);
}
?>

如果Id是自动递增的。
你必须使用
$createsql1="INSERT INTO cruduser(id,username,password) VALUES
                             (NULL,'$uname','$pwd')";

not（（您不能为id值设置字符串。您的id为int类型））
单击“注册”时，您正在发送POST请求中的uname
、pwd
和cpwd
，这些请求被正确地用于插入cruduser
。之后，您将包括crudad.php（include（“crudad.php”）；
）。但请记住，你仍然在接受同样的要求。因此，唯一可用的数据是uname
、pwd
和cpwd
。这就是为什么您的行是半空的。
某些合理的缩进可能是有序的。奇怪的是，您的标签和输入不相等！！！是的，我明白你的意思。对于已更改了某些名称的测试，即使您保留了正确的名称。同样的问题。如何解决。如何在crudadd.php中获取post数据并插入表crud。调整您的第一个表单，使其具有所有必需的字段，或者分两步解决注册问题（例如，不包括cruddd.php，而是重定向到它）良好的重定向效果。还有一个小小的基本疑问。在crudad.php中。我已打开连接并关闭两次，即select为1，insert语句为第二次。打开和关闭连接需要两次，还是只需要一次，我将打开连接并运行选择和插入，最后关闭连接。不需要（也不建议）为每个查询打开连接。事实上，您还可以删除mysqli\u close调用，因为它将在脚本结束时自动关闭（但不建议这样做）。
$createsql1="INSERT INTO cruduser(id,username,password) VALUES
                             ('','$uname','$pwd')";
