I am trying to create a short PHP script that takes $_POST data from a form and does a little math. It generates a table based on the input and an accumulator. However, I canont seem to get the $_POST form input to send to the .php file. I have the correct attributes set for the form tag and I have the method set to "post" in my .html file. I get a jarbled mess when I click the submit button. Im not entirely sure what the deal is. I'm a beginner at this stuff. here's my PHP script
<?php
isset($_POST['loan'])
$amount = ($_POST['$amount']);
$payments = ($_POST['$payments']);
welcome();
createTable($amount, $payments);
function welcome(){
print (<header><h1>Welcome to your personalized Loan Calculation</h1></header>
print <table class=center>);
print <thead><tr><th>Month</th><th>Balance</th></thead>;
}
function createTable ($amount, $payments){
$balance = $amount;
$month=1;
while $balance >= 0);{
$balance = $balance-$payments;
if $balance < 0{
else ($balance = 0) ;
finish($balance, $month);}
createReport($month, $balance);
$month
}
}
function createReport ($month, $balance){
print ("<tr><td>$month</td><td>$balance</td></tr>");
}
function finish($amount, $balance, $month) {
print ("<tr><td> $month </td><td> $balance </td></tr>");
print ("</tbody><tfoot>");
print ("<tr><td colspan=2>Your original balanace was $amount </td></tr>");
print ("<tr><td colspan=2>Developed by Me :) </td></tr>");
}
?>
Now, I've added and removed all of the double-quotes around the table rows several times thinking this was the issue. Using XAMPP to test it out.
any suggestions? been stumped on this for a few days now.
This image is what is rendered when submit button is clicked.

the file should be with .php extension to be able to render PHP
