While inserting data from web forms to databases, trimming the posted values to remove the spaces
from the left and right sides can be a good idea to avoid the user faults. This code have to be
located before the DB operations.
<?php
/* Stripping whitespaces from left and right sides of all posted data.
* Put this before working with posted data.
*
*/
// Remove whitespaces from left and right sides.
function removeSpaces($str) {
$newStr = trim($str);
return $newStr;
}
// If any data posted to the page, send them for trimming.
if ($_POST) {
foreach ($_POST as $var => $value) {
$value=removeSpaces($value);
$_POST[$var] = $value;
}
}
?>
