Yes, now it works. This is beyond my knowledge, thank you.

April 26, 2016

This is interesting...when I open a file in browser ( file > open ) it shows "password" and "confirm password". But when I run it through server ( localhost ) nothing again. Any idea why this glitch?

April 26, 2016

No, and the case is that other inputs are there ( Email Address etc. ). Now I will correct this mistake.

edit: After eding <body> everything stays the same, no password.

April 26, 2016

I created a HTML registration form with input type password but when I run HTML in my xampp server I see no "password" nor "confirm password". Verification shows that my syntax is OK.

I'm attaching this file if you are interested to take a look.

posting.html

April 22, 2016

Ok, I see it> $_POST['last_name];

I forgot a single quotation mark after last_name.

And I also spotted a mistake in line 14. Now everything is fine. I will do my best to try to figure out these beginners mistakes before I post here.

April 22, 2016

I have a problem with this code:

<!DOCTYPE html PUBLIC "-//W3C//DTDXHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

</head>
<body>
<?php // Script 5.2 - handle_post.php
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name];
$posting = $_POST['posting'];
$name = $first_name . ' ' . $last_name;
print "<div>Thank you, $name, for your posting":<p>$posting</p></div>";
?>
</body>
</html>

After I enter data to html form it says:
Parse error: syntax error, unexpected 'posting' (T_STRING), expecting ']' in C:\xampp\htdocs\my-site\handle_post.php on line 12

April 22, 2016

I don't know how is this possible but now html form runs just fine...

April 22, 2016

Do you want me to place this file on external server? I'm not sure how to do that yet. :sorry:

If with html file is the same procedure with wordpress using FileZilla I may try but don't feel like opening new free server address right now.

April 22, 2016

The same problem occures after the change. I don't get why. This is by the book. :Unsure:

April 22, 2016

This is my code:

and this is what I receive:

Any idea why this is happening?

April 14, 2016

beginner's mistake, thanks again. :Bucktooth:

April 14, 2016

Thank you. Now I'm working on ecommerce task. I made a html form for entering data about purchasing and php to handle it and calculates things.

The message that I receive is:

I don't understand what is wrong in line 16: $tax = $_POST['tax'];

The php code checker signalizes the same error.

April 12, 2016

I minor problem this time. I'm practising sending data to server without html form. So, the first code is html with <a href=...> and the second is php that receives data from html.

<!DOCTYPE html PUBLIC "-//W3C//DTDXHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 <li><a href="hello.php?name=Sophie">Sophie</a></li>
 
</ul>
</div>
</body>
</html>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML

	$name = $_GET['name'];
	print "<p>Hello,<span style=\"font-weight:bold;\">$name</span>!</p>";
	?>
22 </body>
23 </html>

This time I received:

3 4 5 6 7 8 9

Hello,Michael!

22 23

Why those numbers appeared? They are propably lines in notepad++.

April 10, 2016

A friend helped me with editing code, this is how it should look:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html" charset="utf-8"/>
    <title>Your Feedback</title>
</head>
<body>
<?php // Script 3.3  handle_form.php
// This page receives data from feedback.php
// It will receive: title, name, email, response, comments, and submit in $_POST.
$title = $_POST['title'];
$name = $_POST['name'];
$response = $_POST['response'];
$comments = $_POST['comments'];
print "<p>Thank you, {$title} {$name}, for your comments</p>
<p>You stated that you found this example to be '{$response}' and added:<br />{$comments}</p>";
?></body>
</html>

So basically, he only added curly braces in quotes to variables in paragraph...

April 10, 2016

I use notepad++. I will procceed with next task and see what will happen. Maybe I'll come back to these that don't work.

April 9, 2016

Yes, I gave a php extension and I use XAMPP that has php installed.

By the way, it did execute php code for some simple things such as phpinfo function. Whenever I made a mistake that needed to be fixed after I did it the server didn't respond well.

April 9, 2016

No hidden extension, I follow the book "PHP for the web" by Larry Ullman. Everything is as in the book. After first few fails I even copy-pasted codes but nothing changes...

After rerunning your edited code it says:

Thank you, '.$title.' '.$name.', for your comments'; echo '

You stated that you found this example to be \''.$response.'\' and added:
'.$comments.'

'; ?>

April 9, 2016

Now the response is:

Thank you, '.$title.' '.$name.', for your comments'; echo '

You stated that you found this example to be \''.$response.'\' and added:
.'$comments.'

'; ?>

Using print should be ok, I have a feeling that something is wrong with my server, XAMPP is in actions but I don't get why these kind of responses for different files that I tried to execute.

April 9, 2016

what I get when I fulfill the html form is:

Thank you, $title $name, for your comments

You stated that you found this example to be '$response' and added:
$comments

"; ?> /body>

April 9, 2016

I am sorry, I don't understand your previous comment.

And I have a similar problem with my next task. I created two files ( html form and php ) but it doesn't execute properly.

Check it if you wish:

Yes, it's with utf-8. It's interesting that when I first wrote the code I made a mistake on line 18. When I corrected that mistake and tried to execute the code but the message was the same.

April 5, 2016

I corrected this line to:

 print "<h1>Basic Info</h1><p>My name is $name, I am $age years old.<br/>My nationality is $nationality. My lastname is $lastname</p>";

...but it still doesn't work and the message I receive is the same.

April 5, 2016

I'm working on my php skills and I run .php files on XAMPP server but it signals parse error even when php code checker sees no problem.

This is one of the codes that I wrote:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML
1.0 Transitional//EN"
 "http://www.w3.org/TR/xhtml1/DTD/
xhtml1-transitional.dtd">
 <html xmlns="http://www.w3.org/1999/xhtml"
xml:lang="en" lang="en">
 <head>5 <meta http-equiv="content-type"
content="text/html; charset=utf-8" />
 <title>Quotes</title>
 </head>
 <body>
 <?php // Script 2.4 - pursue3.php
 $name = "M";
 $age = 29;
 $lastname = 'B';
 $nationality = "S";
 print "<h1>Basic Info</h1><p>My name is $name, I am $age years old.<br/>My nationality is $nationality. My lastname is $lastname</p>"
 ?>
 </body>
 </html>

When I execute this code on my localhost it says: "Parse error: syntax error, unexpected '?' in C:\xampp\htdocs\my-site\pursue3.php on line 18"

It happened with last 3 php files that I wrote. I know what a parse error is, I just don't see where I made any mistake.

March 26, 2016

I'm learning PHP from w3school tutorial and I need explenation about "!", for example take a look at this code:

<?php
$int = 100;

if (!filter_var($int, FILTER_VALIDATE_INT) === false) {
echo("Integer is valid");
} else {
echo("Integer is not valid");
}
?>

Why is there exclamation mark in this code?

And one more thing: if filter_validate_int ( or any other filter ) is false that is because the filter didn't catch any error and therefore, in this case integer, is valid. Did I get this correct?
