Question

Hello i am writing a calculator in PHP and php is working fine, Now what i want is to get value from users.

Im not sure what im missing or i have to use any JS file to do it. I have inbuilt value set $v = 1000000; but i want user to set value as per there need. Also want inbuild remain for defualt user. I think im not using correct way for form.

html

<form action="index.php" method="Get">
Value: <input type="text" name="v" />
<input type="submit" />
</form>

php

<?php
$i = 0;
$v = 1000000;
do {
    $i++;
    $pay  = round($v + $i);
    echo "<tr><td><b>Value</b> $" . number_format($v) . "</td><tr>";
    $v = $v + $bid;
} while ($i <= 5);
?>

I have modified and hide my other personal codes 🙂

fixed: $v = isset($_GET['v']) ? (int)$_GET['v'] : 1000000;

Thanks in advance

Answer 1

As your form uses $_GET you have to assign that to your $v variable, but with condition, if isset.

Change:

$v = 1000000;

to:

$v = isset($_GET['v']) ? (int)$_GET['v'] : 1000000;
