I'm interested in getting into the designing of Wordpress, i can basically code a normal web-page from scratch, but was wondering how much harder it is to do it for Wordpress and if i will have to learn anything else, so please let me know and feel free to post tutorials.
Very easy, follow the guides in the codex or google around, its just a few php lines and your standard css styling GL!
WordPress is easy to work with. Download some free templates and look at their code. Strip down a template and start modifying it. Do this a couple times until you get the hang of WP basics. From there, you can try to create your own theme from scratch. Once you get good at making themes, you can sell them and make money. You can also offer custom theme creation services. Good luck with learning.
My advice is pretty much like the others on here, download a simple theme and reverse engineer it and see how it works. It is pretty easy after that and that is how I learned.
Read this, and that's enough for getting started. http://vandelaydesign.com/blog/wordpress/tutorials-for-developing-wordpress-themes/ When this is done, you will definitely know where to go, and what keyword to use in Google to learn more.
Sir, can anyone send me anylink to the wordpress e-book. i want its documentsion because i have to create a cms usin wordpress.
You want to create a CMS using Wordpress? I don't think that is allowed. Wordpress is really easy to code with. I build websites with Wordpress for all my clients. It looks like real websites too - so they never complain. If you know HTML, you know Wordpress... even though Wordpress is built on PHP, it's similar to HTML.
