  12. Check here If(empty($username){ echo ' user name is required'; } At the same time We have written a jQuery that prompt the message 'user name is required' if he/she submit an empty value. Here all warning message will be printed at the same time, and it is going to be a bad idea since we have two messages at the same time. So how to handle this?!
  13. Is jquery/Ajax better than real/raw PHP for form validation ?! What if JavaScript is turned off on the browser?! why after someone refreshing a page on the browser, the variables used to echo error after invalid data is being submitted will return the undefined variables error?! And how to handle form validation including an empty form field, maximum amount of value entered and so on

  21. One sure-fire way to get people to not help you is to tag them and plead for their help. What RewriteRule have you tried to do this? "Can't" do that with just mod_rewrite. The problem is that you want to replace spaces with hyphens. What you can do is rewrite /article/this-is-new-product to /article?title=this-is-new-product. So first make your article.php support that. When that's ready, What RewriteRule have you tried to do this? check on the htacess above
