Re: Beginner question on using PHP and POST

Show all headers | View raw

Dan,

Two things:

> $food=htmlspecialchars($_GET["food"]);

You are POSTing, but are inspecting the $_GET array ?  No wonder you do not 
get anything (see what I did there ? :-) )

Suggestion: Try to inspect the $_POST array instead.

Some info: https://www.php.net/manual/en/reserved.variables.post.php

> I tried echo, readfile, etc but got nothing...

Correction, you did not /see/ anything.

Next time when you are not sure what, or even if you should see anything 
delimit the output with a few know characters.   My favorites are the square 
brackets:

echo "[". $food ."]"

Maybe throw in a carriage-return and linefeed for good measure too:

echo "[". $food ."]\r\n"

remark: Apologize for any errors or glaring omissions - I'm a PHP novice 
myself too. :-)

Regards,
Rudy Wieser
