PHP存储变量

标签: php mysql

我有这个代码(如下所示)和变量$ first_name = $ _ POST ['first_name'];似乎不起作用。我有用户名,密码和标题工作。是否与使用下划线有关?我检查过它与数据库匹配。当用户创建一个帐户时,存储first_name的行会引发错误,并且不会显示在数据库中输入的名称。有什么想法吗?

<?php
/* This code will make a connection with database */
$con=mysql_connect("localhost","","");

/* Now, we select the database */
mysql_select_db("");

/* Now we will store the values submitted by form in variable */
$username=$_POST['username'];
$pass=$_POST['password'];
$title=$_POST['title'];
$first_name=$_POST['first_name'];
/* we are now encrypting password while using md5() function */
$password=md5($pass);
$confirm_password=$_POST['confirm_password'];

/* Now we will check if username is already in use or not */
$queryuser=mysql_query("SELECT * FROM Customer WHERE username='$username' ");
$checkuser=mysql_num_rows($queryuser);
if($checkuser != 0)
{ echo "Sorry, ".$username." is already been taken."; }
else {

/* now we will check if password and confirm password matched */
if($pass != $confirm_password)
{ echo "Password and confirm password fields were not matched"; }
else {

/* Now we will write a query to insert user details into database */
$insert_user=mysql_query("INSERT INTO Customer (username, password, title, first_name) VALUES ('$username', '$password', '$title', '$first_name')");

if($insert_user)
{ echo "Registration Succesfull"; }
else
{ echo "error in registration".mysql_error(); }

/* closing the if else statements */
}}

mysql_close($con);
?>

谢谢!

问题是first name的输入文字的表单属性为name而不是first_name。所以你应该改变

$first_name=$_POST['first_name'];

$first_name=$_POST['name'];

或将您的名称属性更改为first_name

在插入

之前,还要对所有字段进行适当的转义
<?php
/* This code will make a connection with database */
$con=mysql_connect("localhost","","");

/* Now, we select the database */
mysql_select_db("");

/* Now we will store the values submitted by form in variable */
$username= mysql_real_escape_string($_POST['username']);
$pass= mysql_real_escape_string($_POST['password']);
$title= mysql_real_escape_string($_POST['title']);
$first_name= mysql_real_escape_string($_POST['name']);

/* we are now encrypting password while using md5() function */
$password= md5($pass);
$confirm_password= mysql_real_escape_string($_POST['confirm_password']);

/* Now we will check if username is already in use or not */
$queryuser=mysql_query("SELECT * FROM Customer WHERE username='$username' ");
$checkuser=mysql_num_rows($queryuser);
if($checkuser != 0)
{ echo "Sorry, ".$username." is already been taken."; }
else {

/* now we will check if password and confirm password matched */
if($pass != $confirm_password)
{ echo "Password and confirm password fields were not matched"; }
else {

/* Now we will write a query to insert user details into database */
$insert_user=mysql_query("INSERT INTO Customer (username, password, title, first_name) VALUES ('$username', '$password', '$title', '$first_name')");

if($insert_user)
{ echo "Registration Succesfull"; }
else
{ echo "error in registration".mysql_error(); }

/* closing the if else statements */
}}

mysql_close($con);
?>

改变它:

$first_name = mysql_real_escape_string($_POST['first_name']);

您目前正在保存而没有任何消毒或逃避。

答案 2 :(得分:0)

改变这个:

$insert_user=mysql_query("INSERT INTO Customer (username, password, title, first_name) VALUES ('$username', '$password', '$title', '$first_name')");

对此:

$insert_user=mysql_query("INSERT INTO Customer (username, password, title, first_name) VALUES ('".$username."', '".$password."', '".$title."', '".$first_name."')");

<强>更新

请检查<input type="text" name="first_name">是否有name="first_name"

好吧,看起来您的表单不包含first_name项,而是name。将其更改回first_name
