It is, and variables *are* case sensitive in PHP.

Where do you actually define $password?

You are absolutely correct. Just check mysql_num_rows has at least one record.

You could always store a copy of the $_POST array into the users $_SESSION array (or even just the values you want) when the form has been submitted then easily restore them from there.

There's a hell of an echo in here.

You are NOT coming to this board for every error in this CMS. Read this: http://www.php.net/manual/en/migration5.php

Variables are not interpolated within single quotes.

At the top of any scripts. Preferably somewhere where it will be included into every page.

If you really have these types of concerns don't use shared web hosting.

Asking the types of questions you are asking I would suggest the first thing to do would be to forget the idea of a 'social networking' site for now and learn HTML & CSS. Once you are comfortable with them, you could probably start looking at learning PHP.

Without knowing what code it is you downloaded it's pretty hard to help. If it's a framework of some sort you can likely just put it on your include_path and use an auto loader of some sort. Have you tried looking through the documentation for clues?

Yes. You need to make sure all classes are included properly.

It is an extension, so yes. You will need to ask your host if they support it or if they could install it.

Please, we have tags for use when posting code, please use them.

Have you actually got a specific question? Where exactly are you stuck? Have you even looked at twitter's developer documentation?

Take a look at the ffmpeg extension.

There might be a little more to it than that, ie some other parts of the script might relie on you being logged in, but yeah, I'd start there.

Right near the top of that script you are checking to see if the user is logged in.

HTML/CSS - I started making sites around 1998 - 1999. Iv'e never been much of a designer though. ASP (VBScript) - Worked with between 1999 - 2002. Python - I switched from Windows to Linux and Python looked interesting. 2002 PHP - Getting back into web development. 2004 There are of course other languages which I've used. Bash I use on a daily basis and have done since I started using Linux, and I've played with my fair share of Perl. I've been using PHP for a long while now and really am starting to look for alternatives (even though I'm employed mostly as a PHP developer). I'm not really that interested in web development either these days, which is OK, we don't make web sites (as such) where I work. I'm thinking Ruby is looking like a prime candidate for good use. Been playing around with it for probably the last 12 months, and in the last few months looking at Rails. Node.js is also pretty interesting.
