I have now tried to add many of the security hints on a web page and
come to a problem.
I am checking if the allowed fields match the sent fields.
>From the database I get the information if a checkbox is checked or not:
<?php if($DB_a =="y") {
$checked="checked";
} else {
$checked="";
}
?>
<input type="checkbox" name="R_a" value="y" <?php echo $checked ?>
If the user takes out the checkmark the value will become "" and the
field will not submitted which results in a missing field.
$allowed = array();
$allowed[]='form';
$allowed[]='R_a';
$allowed[]='R_b';
....
$sent = $array_keys($_POST);
if($allowed == $sent) {
... do some checking ...
} else {
echo "Expected input fields do not match!";
}
break;
How can I force a "n" for not checked in the input field? or how can I
solve that?
bye
Ronald
