Can you please take a look at this code, from some reason it doesn't work.

OK, I forgot one quotation but the topic is not about that. I am saying that I don't understand the distinguished code.

May 15, 2016

I'm working of registration form and I have a problem with understanding one of the codes.

<?php // Script 8.9 - register.php
define ('DEFINE', 'register');
include('templates/header.html');
print '<h2>Registration Form</h2>
  <p>Register so that you can take advantage of certain features like this, that, and the other things</p>';
print '<style type="text/css" media="screen">
  .error { color: red; }
 </style>';
 if ($_SERVER['REQUESTED_METHOD'] == 'POST') {
    $problem = FALSE;
	if (empty($_POST['first_name'])) {
	   $problem = TRUE;
	   print '<p class="error">Please enter your first name!</p>';
	}
    if (empty($_POST['last_name'])) {
	   $problem = TRUE;
	   print '<p class="error">Please enter your last name!</p>';
	   }
	if (empty($_POST[email'])) {
	   $problem = TRUE;
	   print '<p class="error">Please enter your email address.</p>';
	   }
    if (empty($_POST['password1'])) {
	   $problem = TRUE;
	   print '<p class="error">Please enter a password.</p>';
	}	 
    if ($_POST['password1'] != $_POST['password2'])	 {
	   $problem = TRUE;
	   print '<p class="error">Your password did not match your confirm password.</p>';
	}
	if (!$problem) {
	print '<p>You are now registered.</p>'
	}
	$_POST = array();
} else {
	print '<p class="error">Please try again!</p>
   }
}
?>

this part:

if (!$problem) {
	print '<p>You are now registered.</p>'
	}

Why are we using exclamation mark here? I already defined $problem = FALSE at the beginning of the whole code. That means that there is no problem. If we reverse it to TRUE it will mean that there is a problem with registration but in that case the user shouldn't see "You are now registered". The if condition is fulfilled in any case because with don't have any '<', '>' or '=='.

If you wish to use PHP then the file extension needs to be changed to .php

Thank you, I didn't know this...In the book it's not mentioned. Now it works fine.

May 13, 2016

I don't think so, this html executes and I see content.

here is the page:

I'm making now a template and within header.html I placed two date functions but when I run the code I don't see them on the browser. Don't know why, everything is by the book.

I don't understand this array function although I read php manual.

This is an example:


<?php
$array1 = array('blue'  => 1, 'red'  => 2, 'green'  => 3, 'purple' => 4);
$array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan'   => 8);

var_dump(array_diff_key($array1, $array2));
?>

and this is output:

array(2) {  ["red"]=>  int(2)  ["purple"]=>  int(4)}

I don't see any connection here, why is for example key red different from the key blue in the second array but the key blue from the first arrays differs from the key green in the second array? Or I got this completely wrong?

May 3, 2016

Thanks, and I learn't a new function.

May 2, 2016

So the author of this book is wrong? That's strange...

p.s. I understand that you are right. It doesn't work.

May 1, 2016

I'm working on multidimensiona arrays, I ran this code thru php checker and everything looks fine.

But it sends message:

No BOM. By the way, what is bom?

April 29, 2016

Windows, UTF-8 apply to opened ANSI files.

April 29, 2016

Still the same thing...I give up and moving forward.

April 29, 2016

OK.

handle_reg.php

April 29, 2016

I added '?wellthisis=bull' and receive the same message.

April 29, 2016

And again:
Parse error: syntax error, unexpected '{' in C:\xampp\htdocs\my-site\handle_reg.php on line 33

April 28, 2016

if ( is_numeric($_POST['year']) && (strlen($_POST['year'] ) == 4)) {
	if ($_POST['year'] < 2015) {
		$age = 2015 - $_POST['year'];
	} else {
		print '<p class="error">Either you entered your birth year wrong or you come from the future!</p>';
    $okay = FALSE;		
	} 
	
 }	else {
		print '<p class="error">Please enter the year you were born as four digits.</p>';
		$okay = FALSE;
	}

April 28, 2016

After copypaste of your code I receive the same message. If you want I can attach html and php code that you can see it yourself.

April 28, 2016

And now again I receive that '{' is unexpected. I don't understand what is wrong with this curly brace...It's not about parenthesis now...

April 28, 2016

I fixed the previos problem but now the message is: - Please enter the year you were born as four digits.

...and I entered 4 digits. Any idea why this conditional doesn't work?

April 28, 2016

I receive the same message after eding the parenthesis, that '{' is unexpected...

April 28, 2016

Again a thing I don't understand, I'm working on nesting conditionals:

<?php // Script 6.2 handle_reg.php
$okay = TRUE;
if (empty($_POST['email'])) {
	print '<p class="error">Please enter your email address.</p>';
	$okay = FALSE;
}

if (empty($_POST['password'])) {
	print '<p class="error">Please enter your password.</p>';
	$okay = FALSE;
} 
if (empty($_POST['confirm'])) {
	print '<p class="error">Please enter your password.</p>';
	$okay = FALSE;
}
if ($_POST['password'] != $_POST['confirm']) {
	print '<p class="error">Your confirmed password does not match the original password.</p>';
	$okay = FALSE;
}
if ( is_numeric($_POST['year']) AND (strlen($_POST['year'] == 4) ) {
	if ($_POST['year'] < 2015) {
		$age = 2015 - $_POST['year'];
	} else {
		print '<p class="error">Either you entered your birth year wrong or you come from the future!</p>';
    $okay = FALSE;		
	} 
	
 }	else {
		print '<p class="error">Please enter the year you were born as four digits.</p>';
		$okay = FALSE;
	}


if (!isset($_POST['terms']) AND ($_POST['terms'] == 'YES') ) {
	print '<p class="error">You must accept the terms.</p>';
	$okay = FALSE;
 }

if ($okay) {
print '<p>You have been successfully registered.</p>';
print "<p>You will turn $age this year</p>";
}
?>

it says:

Parse error: syntax error, unexpected '{' in C:\xampp\htdocs\my-site\handle_reg.php on line 32

line 32 is: if ( is_numeric($_POST['year']) AND (strlen($_POST['year'] == 4) ) {

Why is opening curly brace unexpected?

April 27, 2016

I used double quotes, it works great. Thank you.

April 27, 2016

An another problem, php code checker see no mistake:

<?php // Script 6.2 handle_reg.php
$okay = TRUE;
if (empty($_POST['email'])) {
	print '<p class="error">Please enter your email address.</p>';
	$okay = FALSE;
}

if (empty($_POST['password'])) {
	print '<p class="error">Please enter your password.</p>';
	$okay = FALSE;
} 
if (empty($_POST['confirm'])) {
	print '<p class="error">Please enter your password.</p>';
	$okay = FALSE;
}
if ($_POST['password'] != $_POST['confirm']) {
	print '<p class="error">Your confirmed password does not match the original password.</p>';
	$okay = FALSE;
}
if (is_numeric($_POST['year'])) {
	$age = 2016 - $_POST['year']; 
} else {
	print '<p>Please enter the year you were born as four digits.</p>';
	$okay = FALSE;
}
if ($_POST['year'] >= 2016) {
	print '<p class="error">Either you enter your birth year wrong or you come from the future!</p>';
	$okay = FALSE;
}

if ($okay) {
print '<p>You have been successfully registered.</p>';
print '<p>You will turn $age this year</p>';
}
?>
</body>
</html>

and I receive:

Registration Results

You have been successfully registered.

You will turn $age this year

I don't understand why it doesn't show $age variable, the formula should be OK.
