i am trying to validate a form so that all required fields are filled before submission. If they are not filled then an error message should appear..

But I keep getting this error:
"Parse error: parse error, unexpected '{' in C:\Program Files\wamp\www\template1\updateReceipt.php on line 31
"

Here is the code

<?php

include("connect.php");

if (!isset($_POST['Submit']))
{

$GpoNumber =$_POST['GpoNumber'];
$invoice=$_POST['invoice'];
$amount=$_POST['amount'];
$receiver=$_POST['receiver'];
$dateIn=$_POST['dateIn'];
$submitter=$_POST['submitter'];

// create empty error variable
$error = "";

// check for data in required fields
if (($GpoNumber == "") || ($invoice == "") || ($amount == "") || ($receiver == "") || ($dateIn == "") || ($submitter == "")) {
    $error = "Please fill in all the required fields!";
}

// validate GpoNumber
[COLOR="Red"]if ((ctype_alpha($GpoNumber) == FALSE {[/COLOR]
    $error = "Please enter a valid GpoNumber <br/>";
}

// validate invoice
if ((ctype_alpha($invoice) == FALSE {
     $error = "Please enter a valid invoice <br/>";
}

// validate amount
if ((is_numeric($amount) == FALSE {
    $error = "Please enter a valid amount <br/>";
}

// validate receiver
if ((ctype_alpha($receiver) == FALSE {
    $error = "Please enter a valid receiver <br/>";
}


// validate date
if ((is_numeric($dateIn) == FALSE {
    $error = "Please enter a valid date <br/>";
}

// validate submitter
if ((ctype_alpha($submitter) == FALSE {
    $error = "Please enter a valid submitter <br/>";
}

Well, read the line in red very carefully. Don't you see a missing ) after false ? Don't forget to change it everywhere.


Edit:
1. Don't create duplicate threads as it will not help you in any way.
2. Please use [code=php] [/code] tags to wrap your code. It really helps.

nav33n is right

I agree with nav33n but I suppose newbies to daniweb aren't familiar to the code tag concept. Also in addition, I would secure that mysql query of yours. The corrected and easier to read code is as follows:

<?php

include("connect.php");

if (!isset($_POST['Submit']))
{

$GpoNumber =$_POST['GpoNumber'];
$invoice=$_POST['invoice'];
$amount=$_POST['amount'];
$receiver=$_POST['receiver'];
$dateIn=$_POST['dateIn'];
$submitter=$_POST['submitter'];

// create empty error variable
$error = "";

// check for data in required fields
if (($GpoNumber == "") || ($invoice == "") || ($amount == "") || ($receiver == "") || ($dateIn == "") || ($submitter == "")) {
$error = "Please fill in all the required fields!";
}

// validate GpoNumber
if ((ctype_alpha($GpoNumber) == false) {
$error = "Please enter a valid GpoNumber <br/>";
}

// validate invoice
if ((ctype_alpha($invoice) == false) {
$error = "Please enter a valid invoice <br/>";
}

// validate amount
if ((is_numeric($amount) == false) {
$error = "Please enter a valid amount <br/>";
}

// validate receiver
if ((ctype_alpha($receiver) == false) {
$error = "Please enter a valid receiver <br/>";
}


// validate date
if ((is_numeric($dateIn) == false) {
$error = "Please enter a valid date <br/>";
}

// validate submitter
if ((ctype_alpha($submitter) == false) {
$error = "Please enter a valid submitter <br/>";
}

thanx dude for giving percisious time

maybe i forgot to mention that I am not very good at PHP i have just started working with it.

so cwarn 23 i dont really understand when you say "I would secure that mysql query of yours".

And nav33n when I place the ) after false I still get the same error .

@SheSliq,

if ((ctype_alpha($GpoNumber) == FALSE

This needs 2 ) to close the opening braces.

if((ctype_alpha($GpoNumber) == FALSE))

Or simply,

if(ctype_alpha($GpoNumber) == FALSE)

And cwarn23 is talking about possible sql injection to your code. A bad user can inject your query with all sorts of unwanted value and take over your database! (drop,truncate, insert, whatever).
Use, mysql_real_escape_string for the user's input to avoid such thing to happen. Also, have a look at cwarn23's code. He has used all kinda prevention techniques to save you from a sql injection! :)
