I need some help here i want to know how do i integrate php login portal in html pages cause i have few pages in html and few php for more information see the attach file.
You can't include php file in html page(only option is to use iframe). Just create one more php file on that include the php login page and html page
You can, but it isn't recommended. You can do it by changing the mapping for .html files so they are processed as .php pages, but that just adds work to the server running .html files through the php scripting engine. If you want to keep the form in an HTML Page, just make sure the form is posted to the appropriate PHP for processing.
You can make an index.php or whatever you need that contains HTML elements, and then for your login form, just call the php file with an include. Works best for me. Your php files can contain all html for that matter, its just when it sees that <?php it knows to use php to process the page.
