Question

我是PHP的新手。我正在建立一个注册页面。当我提交一个按钮时，它会插入到数据库中，这没关系。但是当我想在所有字段都填满时重定向它不重定向。我也使用了header（）。

使用header（）时，它只是重定向但不考虑验证。空字段也在提交。我只是想验证表单，在验证之后，然后提交按钮工作，然后存储并重定向到下一页，在我的情况下是“sucess.php”。

这是代码：

<html>
<head>
<title>Register</title>
<style>
.error{color:blue}
</style>
</head>
<body>
<?php

     $link=mysqli_connect("localhost","root","","all");
        if(!link){echo "not connected";}
$query=mysqli_query($link,"insert into test(name,email,gender,password,cpassword)values('$_POST[name]','$_POST[email]','$_POST[gender]','$_POST[password]','$_POST[cpassword]')");

     $nameErr=   $emailErr= $genderErr= $passwordErr= $cpasswordErr="";
     $name= $email= $gender= $password= $cpassword="";

 if($_SERVER['REQUEST_METHOD']=="POST")
 {
     if (empty($_POST['name']))
     {
         $nameErr="Name required";
     }
     else
     {
         $name=test($_POST['name']);
     }



     if (empty($_POST["email"]))
     {
         $emailErr="Email required";
     }
     else
     {
         $email=test($_POST['email']);
     }
     if(!filter_var($email,FILTER_VALIDATE_EMAIL))
     {
         $emailErr="Invald Email";
     }

     if (empty($_POST["password"]))
     {
         $passwordErr="Password required";
     }
     else
     {
         $password=test($_POST['password']);
     }
     if (empty($_POST["cpassword"]))
     {
         $cpasswordErr="cpassword required";
     }
     else
     {
         $cpassword=test($_POST['cpassword']);
     }
}


function test($valid)
 {
     $valid=trim($valid);
     $valid=stripslashes($valid);
     $valid=htmlspecialchars($valid);
     return $valid;
 }  
 if(test($valid)==true)
 {
    header("location:Sucess.php");
}
{
else "sorry";
}
?>

<p><span class="error">*Required</span></p>
<form method="POST" action=""><?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>>
Name:<input type="text" name="name" value="<?php echo $name;?>"><span class="error">*<?php echo $nameErr;?></span><br><br>
Email:<input type="text" name="email" value="<?php echo $email;?>"><span class="error">*<?php echo $emailErr;?></span><br><br>
Gender<input type="radio" name="gender" value="female">Female<span class="error">*<?php if(isset($gender)&&$gender=="female"){ echo "checked";}?></br></span>
<input type="radio" name="gender" value="male">Male<span class="error">*<?php if(isset($gender)&&$gender=="male"){echo "checked";}?></br></span>
Password:<input type="password"  name="password" value="<?php echo $password;?>"><span class="error">*<?php echo $passwordErr;?></span><br><br>
Confirm Password:<input type="password" name="cpassword" value="<?php echo $cpassword;?>"><span class="error">*<?php echo $cpasswordErr;?></span><br><br>
<?php if($password!==$cpassword){echo "<b><u>password doesnot match<u><b>";}?><input type="submit" name="submit" value="SubmiT">
</form>
</body>
</html>

PHP提交按钮不重定向，如果重定向，则表单未验证
