HTML form submit request

Question

What the difference with POST and REQUEST? Does it recommend if I plan to submit the whole form without the need to write parameters?

link.php?param=1&param=2&param=3

• Pekka: I do not understand what you are talking about. Do you mean the difference between POST and GET? I still don't understand the 2nd part of your question though
• proyb3: Nevermind, learn for others then.

Answer 1

$_REQUEST includes $_COOKIE, $_GET and $_POST.

If you know the type of your request, you are best to use $_GET or $_POST.

• proyb3: so if I POST from index.php to be submit to link.php, how can I get the params to retain in url address with link.php?
• Gazler: You do a submit your form as a GET to pass the variables through the querystring.
• netrox: if you want the form to add values in the URL, you use "<form method="GET" action="blah">

Answer 2

$_POST contains POST data, while $_REQUEST contains POST, query string and cookie data.

Use the specific superglobal as that way you only get data from where you expect.

• proyb3: so if I POST from index.php to be submit to link.php, how can I get the params to retain in url address with link.php?
• Quentin: If you want to pass the data to the handler for the POST request, make them hidden inputs. If you want to make the result of the POST request bookmarkable / linkable, follow the POST-Redirect-GET pattern: en.wikipedia.org/wiki/Post/Redirect/Get
• Omar Al-Ithawi: @proyb3: I guess you should change the <form method="post"> to <form method="get"> is that what you want?
