我是这方面的新手并编写了下面的代码来从MySQL数据库中获取用户数据并将其显示在一个表格中以进行编辑和保存.问题是,它不起作用.任何帮助将不胜感激.
<html>
<head>
<title> Delegate edit form</title>
</head>
<body>
Delegate update form <p>
<?php
$usernm = "root";
$passwd = "";
$host = "localhost";
$database = "swift";
//$Name=$_POST['Name'];
//$Username=$_POST['User_name'];
//$Password=$_POST['Password'];
mysql_connect($host,$usernm,$passwd);
mysql_select_db($database);
$sql = "SELECT * FROM usermaster WHERE User_name='$Username'";
$result = mysql_query($sql) or die(mysql_error());
while ($row = mysql_fetch_array($result))
{
$Name = $row['Name'];
$Username = $row['User_name'];
$Password = $row['User_password'];
}
?>
<form action="Delegate_update.php" method="post">
Name
<input type="text" name= "Name" value= "<?php echo $row ['Name']; ?> "size=10>
Username
<input type="text" name= "Username" value= "<?php echo $row ['Username']; ?> "size=10>
Password
<input type="text" name= "Password" value= "<?php echo $row ['Password']; ?>" size=17>
<input type="submit" name= "submit" value="Update">
</form>
</body>
</html>

玩这段代码.专注于概念,在必要时进行编辑,以便它可以

你没有首先关闭你的开始表格,加上你的代码非常混乱.我不会进入"使用pdo或mysqli语句,而不是mysql",这样你就可以了解自己.你还有一个php标签在它下面打开和关闭,不知道那里需要什么.还有一件事是你的代码引用了一个外部页面,你没有发布,所以如果有什么东西不在那里工作,也可以方便地发布它.
另请注意,表单中的$ row数组变量之间有空格.您必须通过删除空格将这些链接在一起(请参阅我编辑的部分).当涉及到这些错误时,PHP并不宽容.
那你的HTML.我冒昧地纠正了这一点
<html>
<head>
<title> Delegate edit form</title>
</head>
<body>
<p>Delegate update form</p>
<?php
$usernm="root";
$passwd="";
$host="localhost";
$database="swift";
mysql_connect($host,$usernm,$passwd);
mysql_select_db($database);
$sql = "SELECT * FROM usermaster WHERE User_name='".$Username."'"; // Please look at this too.
$result = mysql_query($sql) or die (mysql_error()); // dont put spaces in between it, else your code wont recognize it the query that needs to be executed
while ($row = mysql_fetch_array($result)){ // here too, you put a space between it
$Name=$row['Name'];
$Username=$row['User_name'];
$Password=$row['User_password'];
}
?>
另外,尽量具体."它不起作用"对我们没什么帮助,一个特定的错误类型通常是有用的,加上任何指示代码应该做什么(好吧,这里有点明显,因为它的登录/注册编辑在这里,但对于更大的代码块应该总是解释)
