$_GET and $_POST

mzanimephp

Hi, I need to learn more about the $GET and $POST globals. 🙁 Anyone know a good online tutorial that talks specifically about those? I want to learn how to use PHP to activate forms.

There is nothing to discuss really. $GET contains all GET data (aka stuff from the QUERY_STRING), and $POST contains all POST data. PHP just uses what HTTP provides, so this is pretty straight forward. Forms or no forms, doesn't matter, a form is just one way to create GET and/or POST data...

No wonder I was having trouble thinking of anything to write to him/her... !!

:o guys... I am wanting to know how to create simple forms which users can input text and then receive a result accordingly. I know this is done using $_POST but for the most part thats all I know.

So I guess my question is - what is the most basic bit of PHP code that can be used to build a (working) submit form? Once I figure out the basic requirements I can expand upon that and start eventually experimenting with more advanced stuff.

sigh 🙁

form.html:

<form action="hello.php" method=post>
Enter your name, please:<input type=text name=your_name><br>
<input type=submit name=submit value="Go!">
</form>

hello.php:

<?
echo "Hello, ".$_POST['your_name']."!!";
?>

simple ... you can build from here ...
