Ok, so I have been trying to create a dynamic database driven form. In
the form, there is a list of checkboxes that come from a table in the
database. I can create the list just fine, but when I want to use the
data in the checkboxes, I keep screwing up. There are a few things that
need to be done with the data, but right now, so I can figure out what the
heck I'm doing wrong, all I want to do is submit the form and display the
values. I keep getting this error:
Warning: Invalid argument supplied for foreach() in
/usr/local/packages/apache-1.3.27/htdocs/amccomb/prodev/customer_form.php
on line 563
Why am I so confused about this?
Anyway, here is a snippet of code that is giving me errors. (the form
itself is soooo long, I don't
want to post everything).
Join these list servs:
<?$query = "SELECT * FROM list_serv_t WHERE retired_flag is NULL
OR
retired_flag = 0 ORDER BY list_serv_name";
$search_results = mysql_query($query) or die("Select Failed!"); ?>
<?while ($search_result = mysql_fetch_array($search_results)) {?>
<INPUT
TYPE="checkbox"
NAME="list_serv[<? echo
$search_result['list_serv_cd']; ?>]"
SIZE="20"
MAXLENGTH="50"
VALUE="1"><? echo
$search_result['list_serv_name'] ?> <BR>
<?
}
foreach( $_POST['list_serv'] as $list_serv_cd => $quantity) {
$quantity *= 1; // make it numeric
if($quantity) { // if one exists
echo $list_serv_cd;
}
}
?>
