I've been working on a formmail and I'm trying to get two checkboxes to work. I can get them to echo the correct information but I want the user to be alerted when they haven't picked at least one checkbox. This is my code:
HTML
<td>
<input type="checkbox" name="date1" value="Yes">July 7-11
</td>
<td>
<input type="checkbox" name="date2" value="Yes">July 14-18
<td>
PHP
$date1 = $_POST['date1']; // required
$date2 = $_POST['date2']; // required
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$date1)) {
$error_message .= 'You did not choose a date.<br />';
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$date2)) {
$error_message .= 'You did not choose a date.<br />';
}
$email_message .= "July 07-11: ".clean_string($date1)."\n";
$email_message .= "July 14-18: ".clean_string($date2)."\n";
It makes me choose both checkboxes before it will send the email. I've tried having the inputs have two values and forcing at least one but I can't seem to get anything to work.
