I just start coding in PHP, i wrote my first php + mysql program for inserting data through web form. it works fine, but whenever i refresh the page, it automatically saves null record to my database. i know the solution in .NET is ispostback, but not in php? can somebody give me some idea in PHP.
Code is here:
<body>
<form action="mySQLTest.php" method="post">
First Name :<input type="text" name ="txtFirstName"/> <br/>
Last Name: <input type="text" name ="txtLastName"/> <br/>
Age : <input type="text" name= "txtAge" /> <br/>
<input type="submit"/>
</form>
<?php
$con = mysql_connect("localhost","root","");
if(!$con)
{
die('Could not Connect:' .mysql_error());
}
mysql_select_db("test", $con);
if($_REQUEST[])
{
$sql1 = "Insert into info(FirstName, LastName, Age) Values('$_POST[txtFirstName]','$_POST[txtLastName]','$_POST[txtAge]')";
}
if(!mysql_query($sql1, $con))
{
die('Error: '.mysql_error());
}
else
{
echo "1 Record Added";
}
mysql_close($con)
?>
</body>
