  • Answer:

    If your familiar with building links, you could send input data in a $_GET variable, paste your validation code then redirect to a dynamic link built with the same location as the 1st input. Set up statements to control what to display: <?php if(isset($_POST['gaurav'])){ //Code to validate POST data from input 1 header("location:index.php?postData = true") } if (isset($_GET["postData"])) { echo '<input type="url" name="url" />'; //Code to validate POST data from input 2 } //....and so on ?> That's just a crude example of using GET to dynamically display data through links, best used with urlencode() for security measures, POST already does this. You'll want to refresh the page for each click and use conditionals to decide what to display next. This is best done with an MVC framework like CodeIgniter.

You do NOT want to do that. The moment you make a page writeable you have set up a big hole in the site security. Any hacker can post a script link in their typed url and that link can then make the page edit to include their own code. A common use for this is to make the site an open spam relay if it is hosted as usual on a server with access to email. another is to make your site re-direct as a bank account phishing site, or worse a child porn site. This is often then also used to gain access to other pages on the site. A very quick way to get your site blocked. If you want content on a page to change the correct way is to use a database and then use php to read in appropriate data as required, this allows totally dynamic page building according to user, and the type of content you want to show them. For the operation you show, the best option if to make the click swap out one type and name one as a property of the page and swap in the other type and name using Javascropt onclick. So the page never changes.
