Your if should be like this:

if(isset($_POST['submit'])){
    // check the form inputs
} 

[bradgrafelman]

Or:

if(!isset($_POST['submit']) || $_POST['submit'] == '') {
    // error msg here
}

[nrg_alpha]

if(isset($_POST['submit_x']) && isset($_POST['submit_y'])){
   // do whatever here...
}

Cheers,

plz see

1.html

<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">
 <p>Your name: <input type="text" name="name" size="20" maxlength="40"
value="<?php if (isset($_POST['name'])) echo $_POST['name'];
?>"/></p>
 <p>Your user: <input type="text" name="user" size="20" maxlength="40"
value="<?php if (isset($_POST['user'])) echo $_POST['user'];
?>"/></p>
 <p><input type="submit" name="submit" value="REGISTER"/></p>
</form>

1.php

<?PHP
include_once('1.html');
include_once('db.php');

if(isset($_POST['submit'])){
 if($_POST['name'] != "" || $_POST['user'] !=""){
$name = $_POST['name'];
$user = $_POST['user'];
echo "hi '.$user.' ";
$insert = mysql_query("insert into user values ('".$name."', '".$user."')")
or die("Could not insert data because ".mysql_error());

}else
echo"you entered empty information";
}

?>

when I request 1.php on browse
the result is

you entered empty information

I dont want this msg appear till the user click on submit button

I think you've fixed your problem, I don't get any error message when I first load the page.

<?PHP
include_once('1.html');
include_once('db.php');

if(isset($_POST['submit'])){
	if($_POST['name'] != "" || $_POST['user'] !=""){
		$name = $_POST['name'];
		$user = $_POST['user'];
		echo 'hi ' . $user;
		$insert = mysql_query("insert into user values ('".$name."', '".$user."')")
		or die("Could not insert data because ".mysql_error());
	}else
		echo"you entered empty information";
}

?>

I don't want this msg appear till someone press (submit) button

you entered empty information 

it is confusing. this msg appears in places which I don't want.
when I make refresh also I can see this msg
when I make redirect also it is there.

I need it to disappear untill someone press submit button
then it can show

SHOW YOUR PAGE IN CONTEXT!

You have a html block of code and then a php block of code. Since you have the page being submitted to itself, I assume both those code blocks come form the same file. If you will show the entire file, perhaps, that will help us get to the bottom of the issue. However, the following code...

if(isset($_POST['submit'])){
//...
}

...SHOULD prevent the message "you entered empty information" from being on the page load. However, we cannot know this for sure unless we see your page in context.
