Are you posting any data to this page, as the code is expecting $_POST['languages']

I presume this is a way to show a different block of text based on the users selection... however, if none is made (ie. posted) it will not work.

The block of English doesn't need to be in there twice either - so I have left this in as just the default.

If so, try this (although untested):

<?php 
if(!isset($_POST['languages']))
{
$_POST['languages'] = array('English');
}

foreach ($_POST['languages'] as $language) {
switch ($language) {
case 'Japanese' :
echo "<p>ようこそラフバラ学生連合には、ラフバラ大学では学生の大半は第2の故郷。のためのウェブサイトで、もはや、情報閲覧、お問い合わせフォームを使用することを躊躇しないでください。</p>

<p>してくださいの'デモ再生機能'は、このウェブサイトからあなたの経験を最大限に活用する。何が起こるのか、明らかに必要がある場合英語を話すことがありますか、または別の日程や場所から見ることができます参照してくださいに使用する言語を変更します。</p>

<p>別の便利な機能がある場合は、場所、言語、および、選択した日付に応じて異なる事実を見ることができる'疑似事実'の機能です。</p>";

Actually, what is the foreach needed for? Shouldn't there only be a single language posted? If so, try this:

<?php 
if(!isset($_POST['languages']))
{
       $_POST['languages'] = 'English';
}

switch ($_POST['languages']) {
case 'Japanese' :

You normally get that error message if the argument of foreach is NOT an array.

Pretty well what the error message said!

Foreach iterates through an array, if you dont give it an array then it cant iterate and throws the error.
