noob with noob question


I’ve read several tutorials, but I can’t seem to be able to get my drop down menus to work, I have 10 options and I want when they hit submit the same page shows info exclusive to that option, how do I do that?


Please be more specific with your subject. “noob with noob question” isnt very descriptive and gets rather annoying after a while. :)

Can you post some code so we can take a look at what you are trying to do?


When you get the data from the form, compare it to an array of the possible choices and echo out the ones that don’t match.


sorry about the title :D , anyway, after I compare it to an array, do I do something like if($array[] = 1) {echo “blah”}; like that? Im very new to arrays
here’s the code if it will help

<form action="<?php echo $HTTP_SERVER_VARS['PHP_SELF'];?> method="POST">
<select name="select">
$select = $_POST['select'';
$select = array(
        '1' = '1',
        '2' = '2',
        '3' = '3',
        '4' = '4',
        '5' = '5',
        '6' = '6',
        '7' = '7',
        '8' = '8',
        '9' = '9',
        '10' = '10');

$x.='<select name="select" id="select" onChange="location = this.options[this.selectedIndex].value;">';
	$x.='<option value="#">-Select a Method-</option>'."n";
foreach($select as $key => $method)
	$x.='<option value="?select='.$key.'"'.($key == $select ? 'selected' : '').'>'.$method.'</option>'."n";

	echo $x;



Info on Arrays - or there are a number of websites that explain them - google ‘php arrays’

Psuedocode Ex:

create the possible choices array - look at array()
find out how many options there are - look at count() 
    by not hard coding it you can add options with out worrying about it
start the display (table, form, whatever)
loop through the array - look at 'for' or maybe 'foreach' loops
    if the value of the array element does not equal the $_POST variable 
        echo/print the array element
    end if
end loop
stop the display


Wouldn`t it have been easier just to do:

1 2 3 4 5 6 7 8 9 10 </select?

Or am I missing something?

As your values are the same in the array, you don`t need to have key value pairs in this instance. You could just have done:

$select = array( '1', '2', '3', '4', '5', '6', '7'', '8'', '9'', '10');

Your foreach loop would just have been foreach ($select as $key) and then just echo key for both value and method.

As for accessing things after, well once someone selects something from your drop down, its going to redirect with a $_GET variable. For example:


You then need to do something based on the value selected. For example:

if ($_GET[‘select’]==1)
//do something

or you can use a switch statement:

switch ($_GET['select']) { case "1": do something; break;
 case "2":
 do something;


and so on. Its also worth noting that your drop down is also called ‘select’, so make sure you dont get your $_POST[‘select’] and $_GET[‘select’] mixed up.

Hope this helps.


thanks, that got it!
