I am trying to get my php form to pull data from an sql database but I want to use the check boxes to filter the information it brings back. Can anybody help me on how to get this coded correctly.

You give the checkboxes the same values that are stored in the table

(This code assumes the type columns in the database table are INT)

$typeList = join(',', array_map('intval', $_POST['Type']));

$sql = "SELECT * FROM APS WHERE Paycode='ANM' AND type IN ($typeList) ORDER BY `Date` DESC";

The Type column in SQL is text, would it still work?

[Barand]

if text then the values need to be escaped with real_escape_string

eg

$db = new mysqli(HOST,USERNAME,PASSWORD,DATABASE);

$arr = array (
    'Jones',
    "O'Neill",
    'Smith'
);
$list  = "'" . join("','", array_map(array($db,'real_escape_string'), $arr)) . "'";
echo $list;    //--> 'Jones','O\'Neill','Smith'

Thanks, I will give that a try

Sorry to be a nuisance Barand, Still can't get the coding to work properly. I have been at it all day and about to pull my hair out. I can't get any data to display at all. Not sure what is going on. Even if I change checkbox selections noting happens.

Your form method is GET

Your checkboxes are now called SelType

You haven't submitted the query

 

Apart from that ...

 

try

$SelType = join(',', array_map('intval', $_GET['SelType']));

$sql = "SELECT * FROM APS WHERE Paycode='ANM' AND Type IN ($SelType) ORDER BY `Date` DESC";  
$result = mysql_query($sql);

Awesome!! Thanks heaps. It is working and just how I want it to.

What happened to "text" type

[WAMFT1]

I added another field into the SQL to use the int value for querying and print the text on the display. I then wrote into the export query my end to assign 1 to commission, 2 to wealthtrac and 3 to rebate to insert into the online SQL. That way I would have the best of both worlds.

Better to create a lookup table

 

TABLE type
 +------+------------+
 | type | typeDesc   |
 +------+------------+
 |  1   | commission |
 |  2   | wealthtrac |
 |  3   | rebate     |
 +------+------------+

 

and use a join to get the description

That is what I have done internally before I export to SQL, but I guess it makes more sense to reduce the size of the file and server space.
