PHP: POST undefined index errors

Question

I know there are similar questions asked but none of them are helping in my case.

I have a form written as such:

    <div class = "Contact">
        <form action="formprocessor.php" method="post">
            <label>Name: </label>
            <input name="name" type="text" size="25" />

            <label>Course: </label>
            <input name="course" type="text" size="25" />

            <label>Book: </label>
            <input name="book" type="text" size="255" />

            <label>Price: </label>
            <input name="price" type="text" size="7" />

            <label>Email: </label>
            <input name="email" type="text" size="255" />

            <label>Phone #: </label>
            <input name="phone" type="text" size="12" />

            <input name="mySubmit" type="submit" value="Submit!" />
        </form>
    </div>

and relevant PHP code from formprocessor.php:

<?php
$name = $_POST["name"];
$course = $_POST["course"];
$book = $_POST["book"];
$price = $_POST["price"];
$email = $_POST["email"];
$phone = $_POST["phone"];

echo $name;
?>

Clicking the sumbit button on the form gives me these errors:

Notice: Undefined index: name in /Users/Jose/PhpstormProjects/334 Final Project/formprocessor.php on line 3

Notice: Undefined index: course in /Users/Jose/PhpstormProjects/334 Final Project/formprocessor.php on line 4

Notice: Undefined index: book in /Users/Jose/PhpstormProjects/334 Final Project/formprocessor.php on line 5

Notice: Undefined index: price in /Users/Jose/PhpstormProjects/334 Final Project/formprocessor.php on line 6

Notice: Undefined index: email in /Users/Jose/PhpstormProjects/334 Final Project/formprocessor.php on line 7

Notice: Undefined index: phone in /Users/Jose/PhpstormProjects/334 Final Project/formprocessor.php on line 8

Any help is appreciated. Thanks in advance

Is `formprocessor.php` the same script that displays the form? — Barmar, Mar 29 '16 at 03:42
No, the form is printed through a function in another PHP file. `formprocessor.php` only prints contents of `$_POST` — Jose, Mar 29 '16 at 03:45
Then I can't see a reason why this is happening. Have you tried checking what's being sent using the Network tab of Developer Tools? — Barmar, Mar 29 '16 at 03:46
Seems like the post data is not the expected one. Do print_r($_POST); in your PHP file and check the array values. — Ivan, Mar 29 '16 at 03:35

<?php
if(isset($_POST['mySubmit']))
{
    $name = $_POST["name"];
    $course = $_POST["course"];
    $book = $_POST["book"];
    $price = $_POST["price"];
    $email = $_POST["email"];
    $phone = $_POST["phone"];

    echo $name;
}
?>

I tried that; while it does get rid of the errors, the `echo $name` statements doesn't print anything. – Jose Mar 29 '16 at 03:18
do you have `action` attribute in your form as `action="formprocessor.php"` ?? – Drudge Rajen Mar 29 '16 at 03:38
If you read the form I provided in the question above it'll show that I do, indeed, have an action attribute in my form as `action="formprocessor.php"`. – Jose Mar 29 '16 at 03:42
@Jose oh yeah it is there. My bad. What do you get on `var_dump($_POST)` ?? – Drudge Rajen Mar 29 '16 at 03:45
it prints out `array(0) { }`... – Jose Mar 29 '16 at 03:49
@Jose I check your code. It is working fine . – Drudge Rajen Mar 29 '16 at 03:54

<?php
$name   = isset($_POST["name"]) ? $_POST["name"] : '';
$course = isset($_POST["course"]) ? $_POST["course"] : '';
$book   = isset($_POST["book"]) ? $_POST["book"] : '';
$price  = isset($_POST["price"]) ? $_POST["price"] : '';
$email  = isset($_POST["email"]) ? $_POST["email"] : '';
$phone  = isset($_POST["phone"]) ? $_POST["phone"] : '';

echo $name;
?>
