Re: starting a website in PHP and My SQL

Sorry - that was a bit cryptic.

Your main html sections will probably be "static", e.g. navbars, sidebars, footers, banners etc etc

If you want to give total control - you'll probably need to created 'template' files to hold the various 'static' elements. You don't need a templating system - you can create your own. The following example is just that - not to be taken too seriously - just one way. There are far better ways of doing things I'm sure.

In /templates/main.php

PHP Syntax (Toggle Plain Text)
<?php
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/config.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/functions.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/dtd.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/head_n_body.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/bannerarea.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/nav.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/side.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/main_content.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/footer_n_end.php");
?>
<?php
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/config.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/functions.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/dtd.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/head_n_body.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/bannerarea.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/nav.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/side.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/main_content.php");
  include("{$_SERVER['DOCUMENT_ROOT']}/includes/footer_n_end.php");
?>

Then in your actual displayed page, you could have something like:

PHP Syntax (Toggle Plain Text)
<?php
  include("{$_SERVER['DOCUMENT_ROOT']}/templates/main.php");
?>
<?php
  include("{$_SERVER['DOCUMENT_ROOT']}/templates/main.php");
?>

And that's it. The static content (structural html and the odd piece of static text/logos etc) can be drawn from the individual include files AND/OR from a DB, which is handled by the include files.

The dynamic data from the DB can be placed into placeholder variables within the include files.

PHP Syntax (Toggle Plain Text)
<?php
  $navlist = getNavItems($_SERVER['PHP_SELF']);
//there are better ways of doing this - the function could spit out parsed html containing the navlist (from the DB) pertaining to that page
 ?>
<ul id="nav">
  <?php echo $navlist;?>
</ul>
<?php
  $navlist = getNavItems($_SERVER['PHP_SELF']);
//there are better ways of doing this - the function could spit out parsed html containing the navlist (from the DB) pertaining to that page
 ?>
<ul id="nav">
  <?php echo $navlist;?>
</ul>

Re: starting a website in PHP and My SQL

depends how deep you want to go.

A simple solution would be to login and use a $_SESSION variable to store the verified details.

Each page will have:

<?php
include('includes/login.php');
?>

The login.php file could have something like this:

PHP Syntax (Toggle Plain Text)
if(isset($_SESSION['username'])){
  echo "<p>{$_SESSION['username']} logged in <a href='logout.php' title='log out from site'>[logout]</a></p>";
}else{
?>
<form action="includes/authenticate.php" method="post">
  <label for="username">Username:</label>
  <input type="text" name="username" id="username" />
  <label for="pw">Username:</label>
  <input type="password" name="pw" id="pw" />
<?php
   if(isset($_SESSION['login_error'])){
     echo "<p class='beware'>Username and/or password not correct</p>";
   }
?>
  <input type="submit" name="login" id="login" value="Login" />
</form>
<?php
}
?>
if(isset($_SESSION['username'])){
  echo "<p>{$_SESSION['username']} logged in <a href='logout.php' title='log out from site'>[logout]</a></p>";
}else{
?>
<form action="includes/authenticate.php" method="post">
  <label for="username">Username:</label>
  <input type="text" name="username" id="username" />
  <label for="pw">Username:</label>
  <input type="password" name="pw" id="pw" />
<?php
   if(isset($_SESSION['login_error'])){
     echo "<p class='beware'>Username and/or password not correct</p>";
   }
?>
  <input type="submit" name="login" id="login" value="Login" />
</form>
<?php
}
?>

The above is a very simple login form / logout link display based on $_SESSION variables. The authentication.php page accepts the data from the form and uses this (via $_POST variables) to check against users in the DB. If OK, set the session variables and kill the $_SESSION['login_error'] variable if set. If not OK, set the $_SESSION['login_error'] = 1.
Then return the user to the referring page with the header() command.

Please read up on php/mysql security BEFORE going live with an authentication script. Data validation/verification/sanitizing are essential.

Re: starting a website in PHP and My SQL

It's better if you use ready classes... try: phpclasses.org

Easier, not necessarily better. Learning should be an active experience, rather than passive. If we take the 'classes is better' stance, we'd use Wordpress or similar. Of course some elements of app building will have to rely on ready-made scripts, e.g. wysiwyg editors.

Re: starting a website in PHP and My SQL

I don't know about his Skills, but a starter can't Code everything from scratch! Classes are coded by more experienced coders, and they are provided with examples...

If he (phpangel) wants to learn php & mysql, i would suggest Lynda.com:
1. PHP with MySQL Essential Training (you will learn how to code a php/mysql a simple article site, form the scratch)
2. PHP with.MySQL Beyond the Basics (PHP gallery/OOP)

I agree - you can't do everything from scratch - the above links you note are good places to do some effective learning. My quibble is that a beginner will get very little from professional-level classes as they are usually OOPed and use the most efficient way of presenting conditionals (e.g. ternaries) - this is baffling for many!

Script bunnies can build decent sites, but if something goes wrong, they have little to no idea of how to fix it. As I mentioned a mix of ready-mades for things like wysiwyg editors and novel coding should be encouraged.

Re: starting a website in PHP and My SQL

Croeso (you're welcome) - good hunting.
BTW - you can't go far wrong with a decent book on PHP5/MySQL5. I won't go on and on, but books are peer-reviewed and are usually full of good practice. O'Reilly and Wrox have good publications.
