PHP Ver 7 - Undefined index: eating - Post method

Question

I was making a simple form for getting data stored into variable.

My HTML Code:

<form class="form-horizontal" role="form" method="post" action="result.php">

    <div class="form-group">
      <label for="eat" class ="control-label col-md-3">Eating:</label>
        <div class="col-md-6">
            <input type="number" class="form-control" id="eating" placeholder="Hours Spent Eating Everyday">
        </div>
    </div> 
</form>

<div class="col-md-12">
<center><button type="submit" class="btn btn-default">Let's Know What You DID!</button></center>
</div>

MY PHP Code:

<?php 
$eat = $_POST["eating"];
?>

Error I'm Getting:

Notice: Undefined index: eating Notice: Undefined variable: eating Please help me out, I am using WAMP with Version 7 of PHP.

How is that form submitted? – arkascha Nov 26 '16 at 14:48 — arkascha, Nov 26 '16 at 14:48

Change this line

<input type="number" class="form-control" id="eating" placeholder="Hours Spent Eating Everyday">

to

<input type="number" class="form-control" name="eating" placeholder="Hours Spent Eating Everyday">

POST is referencing the name, not the ID.

I also dont see a submit button, you might want to add that to your answer – RiggsFolly Nov 26 '16 at 14:53
@RiggsFolly Edited the main post. – Nov 26 '16 at 14:55
Are you including the submit button within the form code? It needs to be before `` – Ben Nov 26 '16 at 14:56
@Ben Lol yes, i am. – Nov 26 '16 at 14:57
Its not me with the question. @AviThour all inputs must be between the `

` including the submit button – RiggsFolly Nov 26 '16 at 14:57
Also make sure you're actually inputting a value when your testing it. You're not checking if the value is set before using it in your PHP code so if it is left blank then it isn't going to work. – Ben Nov 26 '16 at 15:00

In html:

<input type="number" class="form-control" id="eating" placeholder="Hours Spent Eating Everyday" name="eating">

In php

If(isset($_POST["eating"])){
 $eating = $_POST["eating"];
}

Alright, fixed all my errors. Thanks alot! – Nov 26 '16 at 15:03
I am getting error at this line: $totalhours = $eating; and the error is: Undefined variable: eating – Nov 26 '16 at 15:05
@AviThour This is likely because you aren't entering a value for eating when the form is being submitted. This means the variable isn't set because of the is set check. – Ben Nov 26 '16 at 15:08
@Ben I am entering a value for sure and i don't know why its error. – Nov 26 '16 at 15:10
