PHP 不执行更新

发布于 2024-12-10 19:22:08 字数 4930 浏览 0 评论 0原文

我创建了一个数据库，其中包含用户的名字、姓氏、电子邮件和临时密码。当用户第一次登录时，他们会看到一个个人资料，其中包含数据库中已有的信息以及他们必须填写的一些附加字段。单击“提交”后，表单应该会更新他们在数据库中的个人资料，但并没有。该数据库称为“用户”。有人可以告诉我我做错了什么吗？

 <?php
$testerID = preg_replace('#[^0-9]#i', '', $_SESSION["id"]); // filter everything but numbers and letters
$tester = preg_replace('#[^A-Za-z0-9]#i', '', $_SESSION["tester"]); // filter everything but numbers and letters
$password = preg_replace('#[^A-Za-z0-9]#i', '', $_SESSION["password"]); // filter everything but numbers and letters

include "scripts/connect_to_mysql.php"; 
    $sql = mysql_query("SELECT * FROM users WHERE id='$testerID' AND username='$tester' AND password='$password' LIMIT 1"); // query the person
    $row = mysql_fetch_array($sql);
    $fname = $row['fname'];
    $lname = $row['lname'];
    $email = $row['email'];

$existCount = mysql_num_rows($sql); // count the row nums
if ($existCount == 0) { // evaluate the count
     echo "Your login session data is not on record in the database.";
     exit();
}

I created a database with user's first name, last name, email, and temp password. When a user logs in for the first time they are shown a profile with the information already in the database as well as some additional fields they must fill in. On clicking submit the form should then update their profile in the database but it doesn't. The database is called 'users'. Could someone please tell me what I'm doing wrong?

 <?php
$testerID = preg_replace('#[^0-9]#i', '', $_SESSION["id"]); // filter everything but numbers and letters
$tester = preg_replace('#[^A-Za-z0-9]#i', '', $_SESSION["tester"]); // filter everything but numbers and letters
$password = preg_replace('#[^A-Za-z0-9]#i', '', $_SESSION["password"]); // filter everything but numbers and letters

include "scripts/connect_to_mysql.php"; 
    $sql = mysql_query("SELECT * FROM users WHERE id='$testerID' AND username='$tester' AND password='$password' LIMIT 1"); // query the person
    $row = mysql_fetch_array($sql);
    $fname = $row['fname'];
    $lname = $row['lname'];
    $email = $row['email'];

$existCount = mysql_num_rows($sql); // count the row nums
if ($existCount == 0) { // evaluate the count
     echo "Your login session data is not on record in the database.";
     exit();

您拥有 isset($_POST['$new_password']) 而不是 isset($_POST['$new_password'])。注意添加的 $

如果你的sql中有错误，那么找出错误的最好方法是添加错误检查代码，

or die(mysql_error());

我已将其添加到你的查询末尾

$sql_update = mysql_query("UPDATE users SET email='$new_email', password='$new_password', phone_model='$phone_model', carrier='$carrier' WHERE id='$testerID'") or die(mysql_error());

if there is an error in your sql then the best way to find out what it is, is to add in error checking code

or die(mysql_error());

i have added it to the end of your query here

$sql_update = mysql_query("UPDATE users SET email='$new_email', password='$new_password', phone_model='$phone_model', carrier='$carrier' WHERE id='$testerID'") or die(mysql_error());
