Question

I have series of checkboxes whom value I am taking and generating a string like….if checkbox is selected I add ‘1’ to string and if it is not selected I add ‘0’ to string.

<input type="checkbox" name="auth_0" id="auth_0" class="checkboxes" value="Yes"/>

My php script is…

if (isset($_REQUEST["save"])) {
/*      echo $_REQUEST['auth_0'];*/
   for ($i = 0; $i <= 49; $i++) {
        if ($_REQUEST['auth_[$i]'] == 'Yes') {
            $auth_string .= '1';
        } else {
            $auth_string .= '0';
        }
    }
    echo $auth_string;
}

Though string is generating but its value is always 0 in both cases that if checkbox is selected or not.

Answer 1

    if ($_REQUEST['auth_[$i]'] == 'Yes') {
    //            ^---------^--- should be " instead

using ' tells PHP to not parse/interpolate variable values inside the string. use " instead.
