Trying to post data by clicking button, but in response getting null in php script
here is html
<input type="button" id="btn" value="View Menu" style="padding: 5px 10px; background-color:green;"/>
here is jquery
var action = 1;
$("input").on("click", sendData);
function sendData() {
if ( action == 1 ) {
$("#btn").css("background", "red");
var getData = 1;
$.post({
url: "drain.php",
type: "POST",
data: {"getData" : getData}
});
action = 2;
} else {
$("#btn").css("background", "green");
var getData = 0;
$.post({
url: "drain.php",
type: "POST",
data: {"getData" : getData}
});
action = 1;
}
}
And here is the PHP Script where I'm trying to receive data (getData)
$rcvd_data=filter_input_array(INPUT_GET,[
'data'=>FILTER_SANITIZE_STRING,
'dev_id'=>FILTER_SANITIZE_STRING
]);
if($rcvd_data !== FALSE && !is_null($rcvd_data)) {
$fp=fopen('drain.txt', 'a+');
fwrite($fp, implode(', ', [
0=>date('Y-m-d h:i:s A', time()),
1=>$rcvd_data['data'],
2=>$rcvd_data['dev_id']
]) . PHP_EOL);
}
$getData = $_POST['getData']; // here the posted data is recieved
echo "@".$getData."#";
die();

As @Dave says, you have not shown us everything. You saygetting null in php script- so show us the PHP script. If you want to check if your AJAX is firing at all, use your browser's dev tools, watch the network tab to see if the POST happens, and inspect it to see what data is POSTed.
