Ok so processing forms is simple in php:
say you have the form:
CODE
<form action="check.php" method="post" >
<label>Enter Some Text:</label>
<input type="text" name="some_text" /><br />
<input type="submit" value="Process" />
</form>
Couple of things to take note here, action is where the information is going to be sent, and what action will be done, and method is how that information will be transfered, in this case it is post, and we will use the $_POST global array, and finally name in the input field is the value of the data that is going to get passed in the $_POST array.
So now that we have a form let's create some php to process that form. So when you hit the submit button it will go to check.php which is a file, and here is a simple thing you can do.
CODE
<?php
$text_info = $_POST['some_text'];
print $text_info;
?>
This little bit of code should print out whatever you put into your text field on the form. Notice how the name of the text field was the reference in the $_POST array. Also another handy function to know about when working with forms (and arrays in general) is the print_r() function, this takes in an array and prints out the contents of the array. I say this is useful because sometimes you can have big forms and you might mistype something, so it helps figuring that stuff out. So if you put that in the code:
CODE
<?php
print_r($_POST);
$text_info = $_POST['some_text'];
print $text_info;
?>
It should print out the contents of $_POST, also to get a better look at what print_r does you can view the page source, and it will be formatted better.
Hope this helps.
