I have some data input area.Here is my file.
Here is my db.php:
<?php
$username = "root";
$password = "";
try {
$db = new PDO('mysql:host=localhost;dbname=task', $username, $password);
echo "Connection Successfull";
} catch (PDOException $e) {
die("Error: Database connection");
}
?>
And my index.php is:
<?php
include "db.php";
?>
<!DOCTYPE html>
<html>
<head>
<title>This is title</title>
<link href="style.css" rel="stylesheet" type="text/css">
</head>
<body>
<div class="wrap1">
<form method="POST" action="">
<input type="text" name="name" required> Username</br></br>
<input type="email" name="email" required> Email</br></br>
<input type="text" name="website" required> Website</br></br>
<input type="submit" value="Submit">
</form>
</div>
<?php
$username = $_POST['name'];
$emailadd = $_POST['email'];
$webadd = $_POST['website'];
$sql = "INSERT INTO users (name,email,website) VALUES ('$username','$emailadd','$webadd')";
if(empty($username) || empty($emailadd) || empty($webadd)){
echo "Please input all field";
}
else{
if ($db->query($sql)) {
echo "Inserted!";
}
else{
echo "Error";
}
}
$db = null;
?>
</body>
</html>
When i first go to index.php page then it's showing some notice.
Notice: Undefined index: name in C:\xampp\htdocs\techmasters\begin\index.php on line 21
Notice: Undefined index: email in C:\xampp\htdocs\techmasters\begin\index.php on line 22
Notice: Undefined index: website in C:\xampp\htdocs\techmasters\begin\index.php on line 23
but if i input any data then it going to be inserted fine.My problem is that if i reload the browser then previous inserted data going to inserted again.How can i solve this problem?
Thanks in advanced.
