check the server method post or get using php

Here is a basic usage method for checking if the server is in post or get mode. most normal pages are served in get mode.

You can send data back to a page using get by adding variables to the string like the following:

index.php?myvariable=value

1st lets see what the current server method by assigning $_SERVER['REQUEST_METHOD'] to a variable.

if(isset($_SERVER['REQUEST_METHOD'])) {
  $server_request_method = $_SERVER['REQUEST_METHOD'];
} else {
  $server_request_method = "";
}

The current server method is: GET

Check for POST method

if($_SERVER['REQUEST_METHOD']=="POST") { 
  // grab some post variables... if there are any. 
}

Check for GET method

if($_SERVER['REQUEST_METHOD']=="GET") { 
  // grab some get variables... if there are any. 
}

Testing Postback

here you can post back some data to see if its working correctly. if you dont set the action of the form it should post back to the current url. clicking submit below will post back the test variable with the value foo


if($_SERVER['REQUEST_METHOD'] == "POST") {
  if(isset($_POST['test'])) {
    $test_data = $_POST['test'];
    $test_data = strip_tags($test_data);
    $out .= "Post Test Result: 
$test_data
";
  }
}

Test result will appear below.
