I'm trying to save the data that "buchen.php" get in php variables but I keep getting the following error
Warning: Undefined array key "reise_id" in buchen.php on line 4
Warning: Undefined array key "platz_geb" in buchen.php on line 5
Can anyone tell what could be wrong here?
var xhr = new XMLHttpRequest();
xhr.open('POST', 'buchen.php');
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.send(JSON.stringify({
reise_id: "<?php echo $reise_id; ?>",
platz_geb: platz_blau
}));
//buchen.php
$reise_id = $_POST['reise_id'];
$platz_geb = $_POST['platz_geb'];
Instead of grabbing the POST variables as always, try the following on the PHP code:
$json = file_get_contents('php://input');
echo $json;
