check if radio button is checked wihout using javscript or jquery
I have a form in which i have two radio buttons, both having name attr equal with "status", i want to check if the user checked at least one radio button and if not throw an error message, and set a flag variable to 1 to make some further checks.
i trying by checking that way
if(!isset($_POST["status"]) || empty($_POST["status"])){echo "<p> you must choose missing/found</p>";$flag =1;}
but i have the error msg from the beginning before the user press the submit button. I know is because the radio buttons are not set but how do i do that without using javascript?

Radios usually require usingisset()and not (just)empty(). You should show us the form for this that contains the radios and the form's method.

Check$_SERVER['REQUEST_METHOD']to see if the form has been posted before checking whether the radio button was selected or not.

@rickdenhaan thank you, it worked.. can you give me a brief explanation of how $_SERVER['REQUEST_METHOD'] works?

$_SERVER['REQUEST_METHOD']contains the HTTP request method used to access the page. At the initial visit, the form is not submitted and the browser has (most likely) issued aGETrequest. Most (certainly not all!) forms are submitted using thePOSTrequest method, so checking for that before attempting to process the form can usually solve problems like this.

If you submit the form with a button element with attributes type="submit" and name="something", a variable is set for this button also in the request. Eg. $_POST['something'].
So if you check if this variable is set, you know the form is submitted.
if(isset($_POST['something'] && (!isset($_POST["status"]) || empty($_POST["status"]))){
echo "<p> you must choose missing/found</p>";
$flag =1;
}
