You can strip the <br/> from the string using:
$string = str_replace ('<br/>', '', $string);

To make an array in an HTML form...
<input type="checkbox" name="correspondence_reference[172]" value="1"
checked /> 172
<input type="checkbox" name="correspondence_reference[173]" value="1" /> 172
<input type="checkbox" name="correspondence_reference[174]" value="1" /> 172
...
Do that for each reference value. Then, in your PHP when you're grabbing the
POST data, you can just loop through the array to see what's been "checked"
- actually, only the "checked" items will show in the array. So, let's say,
from above, the 172 and 174 checkboxes were checked, the POST array would
contain the following...
<?
foreach ($_POST['correspondence_reference'] as $index => $value) {
echo "$index => $value";
}
?>
// Output
172 => 1
174 => 1
It doesn't really matter what the "value" of the checkboxes are. As long as
you know the index, then you're good and you can use that information
appropriately. This is one approach. I know there are others though...
Good luck,
