PHP $ _POST数据未在页面之间传递

Question

I've been trying to make a simple html form that passes data to a php page, eventually for insertion into a sql database. I've made forms successfully for but for some reason can't find what the data isn't getting passed in this instance.

Using var_dump($_POST), I see upon submission of the html form there is no data being transferred. I have tried var_dump both within and outside of a if(isset($_POST['submit'])) {}, both with no success. I'm beginning to think it's possibly an issue with my php install or something along those lines?

HTML FORM:

<form action="programinsert.php" method="POST">
<p>
<label for="program_title"> Program Title: </label>
<input name="program_title" type="text" id="program_title">
</p>
<input type="submit" value="Submit">
</form>

programinsert.php:

<?php
session_start();
define('DB_NAME', 'rluh_website');
define('DB_USER', 'root');
define('DB_PASS', 'swang');
define('DB_HOST', 'localhost');
$link = mysqli_connect(DB_HOST, DB_USER, DB_PASS);
if(!$link) {
    die('Error: ' . mysqli_error($link));
}
$db_select = mysqli_select_db($link, DB_NAME);
if(!$db_select) {
    die('Cannot use ' . DB_NAME . ': ' . mysqli_error($link));
}
var_dump($_POST);
?>

Thanks for the replies everyone. The issue in the end seemed to be when running the web pages (which are hosted locally) from the IDE I am using, PhpStorm. PhpStorm opens up the pages under localhost:63342, rather than plain localhost. Erasing these numbers let the data pass through as expected.

I believe you need to GET what is being posted by the form.

Are you sure database information is correct ? And try adding a "/"
