У меня есть серия выпадающих. Я хочу использовать выбранную комбинацию, чтобы решить, на какую страницу будет перенаправлен пользователь. При отправке я объединяю выбранные значения в переменную PHP $ str. 

 if(isset($_POST['formSubmit'])) 
            {
                $varProjects = $_POST['projects'];
                $varObjects = $_POST['objects'];
                $varYears = $_POST['years'];
                $varMonths = $_POST['months'];
                $userOnly = $_POST['userOnly'];

                $str = $varProjects.'-'.$varObjects.'-'.$varYears.'-'.$varMonths.'-'.$userOnly;

Затем я вызываю функцию. 

echo '<script type="text/javascript">';
                echo 'foo('.$str.')';
                echo '</script>';

Который выглядит так 

<script type="text/javascript">
 function foo(bar) {
      if(bar == "all-all-all-all-") {
          $('#content').load('extern.php');
      }
  }
</script>

Я пробовал передавать переменные, подобные этой, на другие страницы, и это работает, может быть, это что-то внутри функции? Спасибо.

Это то, что ваш код производит 

foo(all-all-all)

Вместо 

foo("all-all-all")

Это потому, что вы неправильно кодируете строку, в ней отсутствуют кавычки. Я предлагаю всегда использовать json_encode при создании переменной из PHP. Это всегда создаст что-то, что является допустимым для JS, будь то строка с символами, которые должны быть закодированы, логическое значение, или число, или массив 

<script type="text/javascript">
  foo(<?php echo json_encode($str)?> ) ;
</script>
