i am quite a beginner in PHP and i wanted to create a input: If you click a button, Javascript will submit it and add linebreak (\n) at the end of what you wrote in the input box, and PHP will write the final result into a file called result.txt. However, when checking result.txt, there is nothing written at all.
HTML
<input id="test" type="text">
<form id="formie" action="test.php" method="post">
<input id="testz" type="text" name="really" hidden="hidden" disabled="disabled"><br>
<button onclick="trigger1()">Submit</button>
</form>
<!-- 2 input boxes, the hidden one is meant to be set to have the final result and with it i do the request -->
<script>
var int;
function trigger1() {
int = document.getElementById('test').value;
document.getElementById('testz').value = int + "\n";
document.getElementById('formie').submit();
}
</script>
PHP
<?php
$postreq = $_POST["really"];
$finaldata = $postreq;
file_put_contents("result.txt", $finaldata, FILE_APPEND);
header("Location: https://domain.tld/test.html");
exit;
?>
No error when stopping the redirect (domain.tld/test.html) and no error in server logs. Why is this happening? I even tried to check this with jshint.com and phpcodechecker.com and both told me no errors
