PHP IF statement help

[talor123]

hey, im new to this site and php..

everytime i enter this code

		$new_user = $_POST["user"];
	$new_password = $_POST["password"];
	$new_password_confirm = $_POST["password_confirm"];
	$new_first_name = $_POST["first_name"];
	$new_sex = $_POST["sex"];
	$new_email = $_POST["email"];


if (empty ($_POST['$new_user'])){ 
header("Location: login.php?message=Enter+a+Username.");
exit;
}

(thats the part with errors)

it tells me i have the "if" statement wrong.. ive also tryed

if($new_user == 0)header("Location: login.php?message=Enter+a+Username.");

exit;

}

 

..ive tryed lots n they all come up with errors, please tell me how to fix it..

and btw this script just meants to make it so when your signing up on the form you cant leave spaces blank..

 

thank you

<?php
// ...

if($new_user == 0)header("Location: login.php?message=Enter+a+Username.");
   exit;
   }

// ...
?>

You haven't included the opening bracket for this IF statement.

It should be:

 

<?php
// ...

if($new_user == 0) { header("Location: login.php?message=Enter+a+Username.");
   exit;
   }

// ...
?>

exit;

}

hey i tryed what you put down.. it comes up saying Parse error: "parse error, unexpected T_IF"  nany ideas what else to do?

just copy and paste and save as login.php

 

 

 

<?php

if(isset($_POST['submit']))

{

$new_user = $_POST["user"];

//$new_password = $_POST["password"];

//$new_password_confirm = $_POST["password_confirm"];

//$new_first_name = $_POST["first_name"];

//$new_sex = $_POST["sex"];

//$new_email = $_POST["email"];

 

if (empty ($new_user)){

header("Location: one.php?message=Enter+a+Username.");

exit;

}

}

 

if(isset($_GET['message'])) {

echo "$_GET[message]";

}

 

echo "

<form action='one.php' method='post'>

<input type='text' name='user' />

<input type='submit' name='submit' value='Submit' />

</form>

";

 

?>

..that would cut lots of stuff out(my full code for the login has lots more to it)..  is there a way i can use a javascript function in a php script?? EG:

<?
javascript:check_all('');

// php stuff goes here
>?

 

or a code to put at then end of a javscript function that runs a php script??..

 

because i just made a javascript up that checks if the fields are empty, thats why it would be good if i could run the javascript function then if everythings filled out it would run the php script.. or something along those lines..

 

thanx
