Why Won't my PHP Form Code work Correctly?

Question

I am trying to create a form in php with an else/if statement that asks the user for their name and age. It greets them with a welcome message and their name, and then if their age is 16 or over, the statement echos "You are old enough to volunteer for our program." If the user is under the age of 16, the statement will echo "Sorry, try again when you are older. Here is my code:

<form action="" method="post">
Name: <input type="text" name="postName">
Age: <input type="text" name="age"><br /><br />
<input type="submit">
</form>
<br />

Hello, 

<?php

echo $_POST['postName'];

?>

!
<br>


<?php

$age = 'age';

if ($age>=16)
{

    echo $_POST["you are old enough to volunteer for our program!"];
}

else {
    echo $_POST["Sorry, try again when you're 16 or older."];
}

?>

The input form is shown correctly, but "Sorry, try again when you're 16 or older" already appears when I open the web page and when I put my name and age in there, the welcome message with the users name works correctly, but absolutely nothing happens with the age statement. It still just says "try again when you're older" no matter what age I put in. HELP :(

Side note, I think you just want to do `echo "You are old enough to volunteer for our program!";` I doubt your key name is *"you are old enough to volunteer for our program!"* — Rasclatt, Feb 06 '17 at 04:45

For starters you need to use $_POST["age"] and not age. Also you should check if you are using get or post using $_SERVER['REQUEST_METHOD'].

If ($_SERVER['REQUEST_METHOD'] == "POST") {
   // HandleForm
} else {
   // showForm
}

what is 'handleform' and 'showform'? I'm very new to php – Evan Michael Higgins Feb 06 '17 at 04:55
Your code that shows the form and handles the form. For your example below the
is handleform and above is show form. – Catprog Feb 06 '17 at 04:58
so then where would I put the "if ($age>=16) if there is already an IF statement for the If ($_SERVER['REQUEST_METHOD'] == "POST") ? – Evan Michael Higgins Feb 06 '17 at 05:01
Inside the if statement. Such as like this answer http://stackoverflow.com/a/11839302/4639242 – Catprog Feb 06 '17 at 05:04
Do i do the same for GET? Like this? if ($_SERVER['REQUEST_METHOD'] == "GET") { – Evan Michael Higgins Feb 06 '17 at 05:39
Nope the get is handled in the else. – Catprog Feb 06 '17 at 07:58
