Hi,
ok, quick description of the problem, I'm trying to reference the postdata from some checkboxes. Unfortunately the checkboxes are dynamically generated therefore I don't know how many there are and thus can't name them individually.
I remember reading that naming them with square brackets (as "name[]") will automatically create an array in the postdata (meaning $_POST[name] is an array) is this true?
anyway, the fact is that my checkboxes are not posting. I print_r($_POST) and it comes back with all expected posts BUT not the checkbox postdata, even if I don't name them with [].
I will post code here for reference, but it's quite long. - <?PHP
-
//$visible=array();
-
echo("<LINK REL=StyleSheet HREF=\"stylesheet.css\" TYPE=\"text/css\">");
-
-
function push(&$array, &$object){
-
$array[] =& $object;
-
}
-
function CleanA($array) {
-
while ($count < count($arr)) {
-
if ($arr[$count] == "") {
-
unset($arr[$count]);
-
}
-
$count++;
-
}
-
return $arr;
-
}
-
-
-
echo("<BODY scroll=\"auto\"><script type=\"text/javascript\">\nfunction changeText(val){\nvar txtArea = document.getElementById('desc');\ntxtArea.value = val;\n}\n</script>");
-
-
$datetoday=date("d/m/y");
-
include("dbconnect.php");
-
db_connect();
-
-
-
echo("<BR><center><FORM name=main action=$PHP_SELF?TID=$TID method=\"post\" >");
-
echo("<SELECT name=\"related\" onChange=this.form.submit()><OPTION></OPTION>\n");
-
$stkgrpqueryedit="SELECT DISTINCT id, service FROM serv_resp_service ORDER BY service ASC";

Hi.
Yes this is true. If you create <input> elements named 'name[]', PHP will threat all of them as an array.
Keep in mind tho, boxes that are not checked will not be included in the post.
For example. -
<?php
-
// Print the FORM
-
$numberOfBoxes = 10;
-
echo '<form action="?" method="POST">';
-
for($i = 0; $i < $numberOfBoxes; $i++) {
-
echo '<br /><input type="checkbox" name="box[]" value="box'. $i .'" /> Box '. $i;
-
}
-
echo '<br /><br /><input type="submit" name="boxSubmit" />';
-
echo '</form>';
-
-
// Check if the data has been posted an print it
-
if(isset($_POST['boxSubmit'])) {
-
echo "<pre>";
-
echo "\n<b>Boxes checked:</b>";
-
foreach($_POST['box'] as $boxName) {
-
echo "\n - $boxName";
-
}
-
echo "</pre>";
-
}
-
?>
-
Will print out all the boxes you checked. The rest will not be a part of the array.

Thanks for confirming that, in that case i'm even more confused. if that is the case the code I am using should definately work, but for some reason the post for the checkboxes is never set...

I see you have two <form> elements. Are you sure you are submitting the right one?

Heya, Tarantulus.
Have you tried submitting the form with the checkboxes checked? Checkboxes do not show up in form results at all unless they are checked.

Doh!
thanks Atli,
I noticed that the checkboxes were in the wrong form element.
