I can't seem to figure these parts out...I have the highlight and table up and running, but these are the parts I'm having difficult with. Help would be awesome!

 

 

"Generate Table with POST using these values"

    Values used in table generation: Clicking this button will submit a form with three table values (row, col, highlight) using the POST method . These POST values will be used in the generation of the table.

    Default Values: The three select boxes are preset to the default values when the page is first entered or the "Generate Table using default values" link is clicked.

    Select Box has Memory: The three select boxes in the form "remember" the values selected from each POST.

 

"Generate Table using GET. "

 

    Always has URL parms: Clicking this link will generate the table using the values stated in the URL parms within this link. This link always has URL parms and is never without them.

    Default Values: The URL parms of this link are set to the default values when the page is first entered or the "Generate Table using default values" link is clicked.

    Acquires POSTed values: The URL parms of this link are set to the values chosen in the three select boxes each time the form is POSTed.

 

Some functions required to use:

 

    The builtin Apache global $_SERVER['REQUEST_METHOD'] was used to determine if the incoming request was a POST or a GET.

    The builtin PHP function count() will return the number of rows in an array.

 

What I have so far:

if ($_SERVER['REQUEST_METHOD'] == 'GET')

I'm guessing this is what you were after.

I cannot reproduce that error, the link works for me. Are you using the code as is, or did you change it?

 

I think I am using the same code:

 

<?
include "greenarray.php";

$rows = 10;
$cols = 10;
$highlight = 5;

$rows = (!empty($_GET['rows'])) ? $_GET['rows'] : $rows;
$cols = (!empty($_GET['cols'])) ? $_GET['cols'] : $cols;
$highlight = (!empty($_GET['highlight'])) ? $_GET['highlight'] : $highlight;

$rows = (!empty($_POST['rows'])) ? $_POST['rows'] : $rows;
$cols = (!empty($_POST['cols'])) ? $_POST['cols'] : $cols;
$highlight = (!empty($_POST['highlight'])) ? $_POST['highlight'] : $highlight;

?>
