$tel = '<font color="red"><b>Your telephone number is invalad</b></font>';

}
else
{
  
  $GLOBALS['message'] = "true";
  
}
$GLOBALS['tel'] = $tel;
}

if($_POST['submit'])
{
checkphone();
 }
 if(!$message){
?>

<?php


function checkemail()	{
global $mail;
$email = $_POST['email'];
	if (!preg_match('/^([a-zA-Z0-9])+([a-zA-Z0-9\.\\+=_-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/', $email)) {
	$mail = '<font color="red"><b>Your Email is invalid</b></font>';
	
	}
	else
	{
	$GLOBALS['message'] = "true";
	}
	$GLOBALS['mail'] = $mail;

**jolicious** · 06-17-2008, 11:56 PM

Thanks for the code and sorry for the slow reply. I would like to ask whats the difference between Globals and SuperGlobals and what do they do. Thanks

**fileserverdirect** · 06-18-2008, 07:57 PM

Globals are variables that are universal throughout the script. So if $var was set inside a function, it could not be accessed by the outside script unless it was a global variable (or vica versa).
SuperGlobals are variables set by PHP itself. A SuperGlobal variable is something like $_SESSION['var']; or $_SERVER['PHP_SELF'];. You cannot create any new superglobals, but you can set them, like: $_COOKIE['time'] = "November 5 1985";. All superglobals start with $_ to Identify them as superglobals and not any ol' user defined variable.
Any other Questions?

**jolicious** · 06-23-2008, 01:56 AM

Thank you for your wonderful explanation on globals and superglobals. I would like to ask afew questions. Can php and javascript work properly together ? And is there a function or way to retrieve the data after clicking the submit button when there is an invalid input ? I'm asking those questions as my supervisor suggested that I can use java to solve the problem but as I'm new to programming it would take quite awhile to learn java. I would like to know how to retrieve data from MS access via php too. I've been searching the web for quite awhile now but most of them I've found are using Visual Basic. Some websites states that ODBC connections are required to make a connection. What is the ODBC connections that is stated and how can I get them ?

Update:I've just came back from my oversea project attachment and now I'm doing my project on another computer with IIS installed into it. I'm manage to setup the IIS and dreamweaver to work together via internet tutorials. However a PHP notice is shown below the form when I run the form. This is the notice : PHP Notice: Undefined index: submit in C:\Inetpub\wwwroot\project5.php on line 28 PHP Notice: Undefined variable: showtel in C:\Inetpub\wwwroot\project5.php on line 33 PHP Notice: Undefined variable: tel in C:\Inetpub\wwwroot\project5.php on line 62 PHP Notice: Undefined variable: mail in C:\Inetpub\wwwroot\project5.php on line 69. No codes were add nor changed during this transition. Thank you for helping me out.
I've temperarily solved the above problem by using error_reporting(E_ALL ^ E_NOTICE). But is there any other way to solve it ?

**jolicious** · 06-30-2008, 08:41 AM

Hi, I've managed to connect to MS Access via ODBC. However a new problem has occured. After clicking on the submit button on the confirmation page, the data from the form are supposed to be saved to the database. But each time I click on the submit button, an internal error 500 would occur. I've tried looking for the error and I feel that it could be due to the code not being able to caputure the data from the form.
Here is the code for the form:

Code:

<?php
error_reporting(E_ALL ^ E_NOTICE);
?>
<?php

function checkphone()    {
global $tel;
$phone = $_POST['hometel'];
  if (!preg_match('/^[0-9]{8}$/', $phone)) {
$tel = '<font color="red"><b>Your telephone number is invalad</b></font>';
  $GLOBALS['tel'] = $tel;       }
 else{
     $GLOBALS['showtel'] = "true";
  }
}


 function checkemail()	{
global $mail;
$email = $_POST['email'];
	if (!preg_match('/^([a-zA-Z0-9])+([a-zA-Z0-9\.\\+=_-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/', $email)) {
	$mail = '<font color="red"><b>Your Email is invalid</b></font>';

	$GLOBALS['mail'] = $mail; }
  else
  {
    $GLOBALS['showmail'] = "true";
  }
	}

 if($_POST['submit'])
{
checkphone();
checkemail();
 }
 	if(!$showtel||!$showmail){
	?>

**jolicious** · 06-30-2008, 09:35 AM

I've found the code thats producing the error its in the database submittion codes. The code thats give an error is :

Code:

<?php
error_reporting(E_ALL ^ E_NOTICE);
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<?php
echo "Your data is successfully submitted";
?>
<?php
$name = $_POST['name'];
$admin = $_POST['admin'];
$gender = $_POST['gender'];
$address = $_POST['address'];
$hometel = $_POST['hometel'];
$hp = $_POST['hp'];
$email = $_POST['email'];
$course = $_POST['course'];
$year = $_POST['year'];
$path = $_POST['path'];
$title = $_POST['title'];
$supervisor = $_POST['supervisor'];
$odbc = odbc_connect('FYP', '', '') or die('Could not connect to ODBC database!');
$input = "INSERT INTO fyp (Name, AdminNumber, Gender, Address, Hometelephone, MobilePhone, Email, AcadCourse, Year, Path ,Projecttitle, ProjectSupervisor) VALUES ("$name", "$admin", "$gender", "$address", "$hometel", "$hp", "$email", "$course", "$year", "$path", "$title", "$supervisor")";
$result = odbc_exec($odbc, $input) or die (odbc_errormsg());
odbc_close($odbc);
?>
</body>
</html>

If i change the " to ', it will submit an empty data input to my database. It seems it can't retreive the data from the form. Can anyone help me out on this code ?

**fileserverdirect** · 06-30-2008, 03:20 PM

O.K. I am so sorry that I have not replyed to any of your posts this past week. I am currently on vacation right now and will be come for a few days but then I will be away again for about two more weeks. I am writing to you from a public library, so please do not take this personal

. I may be able to reply to your upcoming posts, but it may take a while.

-----
POST 1:

Can php and javascript work properly together ?

Yes, very well, it all depends on what your goal that your trying to reach
--

And is there a function or way to retrieve the data after clicking the submit button when there is an invalid input ? I'm asking those questions as my supervisor suggested that I can use java to solve the problem but as I'm new to programming it would take quite awhile to learn java. I would like to know how to retrieve data from MS access via php too. I've been searching the web for quite awhile now but most of them I've found are using Visual Basic. Some websites states that ODBC connections are required to make a connection. What is the ODBC connections that is stated and how can I get them ?

I am sorry that I cannot really help you with this part, I ownly know 1 database language and that's MySQL.
--

However a PHP notice is shown below the form when I run the form. This is the notice : PHP Notice: Undefined index: submit in C:\Inetpub\wwwroot\project5.php on line 28 PHP Notice: Undefined variable: showtel in C:\Inetpub\wwwroot\project5.php on line 33 PHP Notice: Undefined variable: tel in C:\Inetpub\wwwroot\project5.php on line 62 PHP Notice: Undefined variable: mail in C:\Inetpub\wwwroot\project5.php on line 69. No codes were add nor changed during this transition. Thank you for helping me out.
I've temperarily solved the above problem by using error_reporting(E_ALL ^ E_NOTICE). But is there any other way to solve it ?

Try using echo phpinfo(); in both enviorments and compare them and see what you need to switch on or off for this to work correctly.

----
POST 2\3:

In your second post you have one error that could be causing everything to mess up:

<form action="databaseupdatingtestrun.php" enctype="multipart/form-data" method= "post">

That should be this

<form action="databaseupdatingtestrun.php" enctype="multipart/form-data" method="post">

Try that and maybe that might solve the question on your Third post

Any more Questions?

**jolicious** · 07-01-2008, 01:05 AM

Sorry for disturbing you on your vacation. I've tried deleting the empty space but the error is still there. I've tried using a simple code to test if the data can be captured but it still display as a black space.
This is the code :

Code:

<?php
echo "Your data is successfully submitted";
?>
<?php

echo '<p>Name:  '.$_POST['name'].' <br />';

?>

Its ok if you are too busy. You have been really helpful and I thank you from the bottom of my heart.

**fileserverdirect** · 07-01-2008, 03:11 PM

This:



echo '<p>Name:  '.$_POST['name'].' <br />';

Should be this:



echo '<p>Name: '.$_POST["name"].' <br />';

or even:



echo "<p>Name: $_POST['name'] <br />";

Did this solve your problem?
