hello guys i am stuck in a small but horrible problem.i am redirect page to itself using $_server[''PHH_SELF] method but the problem is that i apply the insert query at the top of my html page but it shows me that you are not connect to the DB.

<?php

if(isset($_POST['action']))
{
$con = mysql_connect("localhost","root","");
if ($con)
  {
  die('connected: ' );
  }
  
  else{
	  
	  echo "not connected"; [B][U]// ITS ECHO ME NOT CONNECT WHAT THE PROBLEM I CANT FIGURE IT OUT[/U][/B]
	  }

$db_selected = mysql_select_db("project", $con);



echo $classess = $_POST['class_name'];
$sql = mysql_query("INSERT INTO `classes` (class_name) VALUES ('$classess')");

	

}

?>

Hello
First why you have set die() if connection is successful?

Your problem is not from the PHP_SELF. Your problem is at the top of your code.
You have set $_POST["action"] for it you have to set

<input name="action">

the action at <form> is only to set location for your form. try only with $_POST instead ..
Other thing is to look at your database password you haven't set any? (perhaps for the demo only)..

<?php

if(isset($_POST))
{
$con = mysql_connect("localhost","root","");
if ($con)
  {
  die('connected: ' );
  }
  
  else{
	  
	  echo "not connected"; // ITS ECHO ME NOT CONNECT WHAT THE PROBLEM I CANT FIGURE IT OUT
	  }

$db_selected = mysql_select_db("project", $con);



echo $classess = $_POST['class_name'];
$sql = mysql_query("INSERT INTO `classes` (class_name) VALUES ('$classess')");

	

}

with

action="<?php echo $_SERVER['PHP_SELF']; ?>"

You set to which file you want to post your form data. Its not a POST data which you send only a url which you use.

The $_POST["names"] are coming from your inputs like this one

<input type="text" name="INPUTNAME"  />

This will come out as $_POST["INPUTNAME"]

For your script I can offer you just one easy check
At start just set

if($_POST) { YOUR PHP CODE }

This will work only if you have posted data to your page(with your form).

problem in $_server['php_self']
