I appreciate everyones help. Below what I ended up with to actually delete
the checked boxes.
Lewis
// Deletes specified rows by teacherID.
if(isset($delete_teacher) && isset($deleteID)) {
while (list($key, $num)= each($_POST[deleteID])){
$delete_query = mysql_query("delete from
teacher where teacherID = $num");
print $delete_query;
print "";
}
}
//Checkbox and Submit lines...
print "";
print "";

Re: [PHP-DB] Checkboxes to gather rows to delete
I think the problem is that I need to put the array into a comma delimited
group

Re: [PHP-DB] Checkboxes to gather rows to delete
Thanks. The below code returns each ID in an array like so...
Array ( [0] =>101 [1] => 201 ). Thanks for the help!
Lewis
$teacherID = $_POST[teacherID];
$deleteID = $_POST[deleteID];
if(isset($delete_teacher)) {
This is where I should loop through checking for the chosen ones to
delete.
}
print "";
print "";

Re: [PHP-DB] Checkboxes to gather rows to delete
Thats just it. I am just not sure what to do with the array before my
"delete from" query now that I have it :-)
Thanks...

Re: [PHP-DB] Checkboxes to gather rows to delete
I appreciate all of the quick replies. I do have globals off. Currently, I have the values for each ID being returned in a array Array ( [0] => 101 [1] => 201 ) where 101 and 201 were the id's of the rows I checked. I have to say I like the way of doing it that Mathieu has shown using the explode function. Thanks again.

[PHP-DB] Checkboxes to gather rows to delete
I have a mysql database with a table using one column as a primary key. (rowID). On a php page I use a query to list all of the rows of the table and have a checkbox beside each row that should be used to check if you would like to delete this row. Can someone give me an example using post to pull the boxes that need to be deleted. Thanks!
