Variables available in after [insert_php]

    When I use [insert_php] and populate a variable, is it available outside of the [insert_php] block? Like in my <script>

    ie.

    <head></head>
<body>
  [insert_php]
    $testVar = "Hello";
    echo $testVar . "\n";
  [/insert_php]
  <script type="text/javascript">
    document.write($testVar);
  </script>
</body>

    only produces
    Hello

    It should produce
    Hello
    Hello

    Correct?

    Am I missing something?

    Thanks!

    Sorry, no variable created in an [insert_php] block is available outside that block. More information here:

    To use it in a script tag, it can be done something like this:

    [insert_php]
$testVar = "Hello";
echo $testVar . "\n";
echo '<script type="text/javascript">';
echo "document.write($testVar);";
echo '</script>';
 [/insert_php]

    Thanks for the reply – that’s kind of what I thought also – and had tried something like that before. Here is some more code and I still just get one “Hello” – and we should get two – right?

    ...
       $testVar = "Hello";
       echo $testVar . "\n";
       echo '<script type="text/javascript">';
       echo "document.write($testVar);";
       echo '</script>';
       echo "PHP Code out...";
    [/insert_php]

    Ah the PHP variable needs to be quoted so JavaScript treats it as a string.

    echo "document.write('$testVar');";

    Your JavaScript console should have told you about the error.

    Ah – you’re correct. Thanks so much.
    I’ll check my console more often also.

    Thanks
