ok... first of all... can i send and get checkboxes values to/from $_GET just like $_POST or is there some issues?

i am using this code on the form

Code: Select all

<form name="form1" method="get" action="index.php">

<$php
querydb="select * from uploadsites";
$result=mysql_query($querydb);
while ( $array=mysql_fetch_array($result) ){
	echo "<input type=\"checkbox\" name=\"".array[]." value=\"".$array["id"]."\">". $array["name"].
	"<br>";
}
?>
</form>

but i am having troubles figuring out where to get the values from.
shouldnt they be in

Code: Select all

$_GET["array"];
?


btw, what's the easyest way to print an associative array?

#1. simply using array() as the field name will not work. You'll have to give it a name and add [] after it. For example,

Code: Select all

<input type="checkbox" name="box[]">
If you passed that using $_GET, your url would look something like this

page.php?box=x&box=y&box=3&box=4&box=43

Depending on the amount of checkbox values you had.

The best way is to use $_POST.

I'm not sure what will happen if you print_r($_GET['box']); but you could test it out and see if you get your values into an array.

I had some errors using the quotes...

it was echoing somthin like

Code: Select all

<input type="checkbox" name=">


thx for the printinig tip... btw it outputs something like this
Array ( [0] => 2 [1] => 4 [2] => 5 )

Yeah, you'll have errors using the quotes if you don't escape them properly. You would want to do something like this:

Code: Select all

echo "<input type=\"checkbox\" name=\"box[]\" value=\"".$array['id']."\">";
And since it is working apparently by your output.. you could assign a variable to the array.

Code: Select all

$checkboxvalues = $_GET['box'];

Don't forget that unchecked checkboxes will not get sent by the browser, which is very annoying for dynamically created checkbox names.

thats actually ok for me... i notice that and its cool..

this way i can loop the array containing the ids of the elements checked at once.
