Theres a video on youtube based on a tutorial that describes how to create a web forum, whilst demonstrating the neccessary skills required: http://www.youtube.c...oLPKTxzw&fmt=18

Problem is - I don't understand how to create layouts like he done. I understand a bit of CSS:

 body. {
  background-color: gray;
  border: 2px solid orange;
  font-family: verdana;
  }
 

I can use it in conjunction with <div> tags, but I don't understand how to create full alignments. Take this site for an example, the way it displays all the user generated information in a table like form, printing towards the bottom of the page. After, if it reaches a certain length, it uses pagenition to prevent a stretched page.

I don't understand how I manually create layouts such as the ones you see on this site and other sites.

I also have another annoyance that's bugging me; how can I get php to display certain layouts if a user is logged in for instance, or to not display that layout and to display another if the user isn't logged in.

I tried this...

 if($a == 2)
 {
 echo "
 <div id="test'> Sorry, you must be logged in to do that.  Please login: <a href="login.php"> login </a></div>
";
}
else
 {
 echo "
 <div id="logged_in"> Thank you for logging in '$user' </div>
 ";
}

I need some help on designing layouts in conjunction with PHP

well with the code ur trying it is amost correct, but you are saying $a is equal to 2, you need to say if it equal to 2 then do this so it would look like this

if ($a == 2) {
do this code 
} else {
do the other 
}

a single = sets the variable to the value after it, but to compare a variable to a value you need to use a double ==, so this would be the same for not equal to which looks like !=, not sure if i have explained that well. if you take a look on google for php comparison operators it will be explained a little better or go to the following link on php.net

http://uk2.php.net/m....comparison.php

this might help explain a little more about the problem with your different displaying for logged in and not. i hope this helps you out a little

I'm not talking about small errors we tend to make when writting something up. A little = sign being missing is not the issue. The issue is layouts. I'm trying to design layouts in conjunction with PHP. Thanks anyway.

To write a full layout is a lot of job. I always write everything in (x)html/css and after finish ,b>ALL HTML and CSS codes which will be needed in the future</b> I start interpreting PHP.

for my CSS, I use Dreamweaver, since that's the easier way to go... i don't actually understand CSS at all, really =/

but to display different CSS styles, just set them all up... like this:

<?php
if($a == '1'){
//display CSS Style 1
}elseif($a == '2'){
//display CSS Style 2
}else{
//display CSS Style 3
}

or, if you're going for whether or not someone is logged in, check their sessions using isset or empty...

Alright, sortof getting the hang of writting CSS for layouts. Here's an instance of how I'd write a webpage currently...
[code]
<html>
<head>
<style type="text/css">
#login
{
position: relative;
top: 250px;
left: 250px;
width: 250px;
height: 250px;
background-color: #CCCCCC;
border: 2px solid black;
font-family: verdana;
font-size: 10pt;
padding: 10px;
}
</style>
<body>
<?php
$a = 1;
if($a = 1)
{
echo "
<div id='login'>
<form action='test.php' method='post' id='login'>
Username:
<input type='text' name='username' id='username'>
Password:
<input type='text' name='password' id='password'>
<center><input type='submit' value='login' id='submit'></center>
</div>
";
else
{
print "Welcome $a";
}
?>
</body>
</html>
