I have an html page with checkboxes:
<form action=mailform2.php method=POST>
<input type=checkbox name=option[] value="Modern Mississippi">Modern Mississippi<br>
<input type=checkbox name=option[] value="Civil Rights">Civil Rights<br>
<input type=checkbox name=option[] value="Military History">MilitaryHistory<br>
<input type=submit name=submit value=Submit>
and mailform2.php containing:
echo "you selected: <br>";
/* line 81 */ foreach ($_POST[option] as $a)
{
echo "$a";
}
but I'm getting the error:
you selected:
*Warning*: Invalid argument supplied for foreach() in */var/www/sites/mdah-test/museum/mmhsurvey/mailform2.php* on line *81*
I googled some checkbox/foreach pages on google, but I don't see where I'm going wrong. I'm running php 5.2.5 on Apache 2.2.4 on Fedora Linux. Any help?
