    Setting POST variables

    Hello

    I want to create a script that creates POST's as per a tables contents

    Table Structure
    ID NAME ACTIVE
    1 BOO 1
    2 DOO 1
    3 KOO 1
    4 FOO 1

    The above is my table structure. Right now everything is set to active so I would place this as my POST VARS.

    $_POST['1']
    $_POST['2']
    $_POST['3']
    $_POST['4']

    Now I manually set them on the belief that there would also be 4 ID's. If one was to become inactive, lets say ID 3 did. Then all that should be displayed is:
    $_POST['1']
    $_POST['2']
    $_POST['4']

    How do I achieve this? How can I make it work. I believe I would use some type of while loop with the _POST command. It appears to not work when I do this though.

    Not sure why you want to set $_POST particularly - it will not be carried over to the next request if that is your thinking - but you should be able to do this by looping over the query results:

    PHP Code:
    $result mysql_query("SELECT *  FROM mytable");
    $_POST = array();
    while (
    $row mysql_fetch_assoc($result)) {
        
    $_POST[$row['ID']] = $row['NAME'];

    Mmmm so if I had this on the field:

    <input type="checkbox" name="1" />
    <input type="checkbox" name="2" />
    <input type="checkbox" name="3" />
    <input type="checkbox" name="4" />
    <input type="checkbox" name="6" />
    #5 is missing due to being in active
    <input type="checkbox" name="7" />

    And I used what you mentioned but vise versa.

    $result = mysql_query("SELECT * FROM mytable WHERE active = '1'");
    $row = array();
    while ($row = mysql_fetch_assoc($result)) {
    $row['ID'] = $_POST[$row['ID']];
    }

    I could then do some type of foreach on $row and run a sql for each entry that would work?
