POST without POST data? - php

Question

I am using the following statement to check for post data and set a variable if it comes through via the URL:
if($_SERVER['REQUEST_METHOD']=='POST')
{
$sort = $_GET['sort'];
} else {
$sort = "mgap_ska_id";
}
I need the variable to be assigned a value via POST, but only if the value is passed through the URL. If the URL doesn't contain the variable, the value needs to the a string I can pass to a query. Is it better to use if/then or is some other method better?
Thanks

Answer 1

You have two conditions:
If it's a post request
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
}
Use the get variable if present
$sort = isset($_GET['sort']) ? $_GET['sort'] : 'mgap_ska_id';
Just put them together:
$sort = 'default'; // If it's a get request
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$sort = isset($_GET['sort']) ? $_GET['sort'] : 'mgap_ska_id';
}

Answer 2

just check
if(isset($_GET['sort']){
$sort = $_GET['sort'];
}
else{
$sort = "mgap_ska_id";
}
but don't forget to check for valid data. Never trust a users input.

Answer 3

also you may try following will work with POST and GET Methods
if(isset($_REQUEST['sort']){
$sort = $_REQUEST['sort'];
}
else{
$sort = "mgap_ska_id";
}
For your reference
You should use $_GET when someone is requesting data from your
application.
And you should use $_POST when someone is pushing (inserting or
updating ; or deleting) data to your application.
Either way, there will not be much of a difference about performances : the difference will be negligible, compared to what the rest of your script will do.

Make sure you have a form input field named "sort":
$sort = '';
if($_SERVER['REQUEST_METHOD']=='POST'){
// Sent by POST
$sort = $_POST['sort'];
} else if ($_SERVER['REQUEST_METHOD']=='GET'){
// Sent by GET
$sort = $_GET['sort'];
} else {
// Neither - set a default.
$sort = "mgap_ska_id
}
echo $sort;
