Facing trouble to insert php variable in javascript code

Question

I'm trying to insert php variable in a javascript code but unable to get the result. Code is:

<?php $twitterusername = get_option_tree( 'twitter_name', '', 'true' );?>

<script type="text/javascript">document.write(unescape("%3Cscript src='http://twitterforweb.com/twitterbox.js?username=$twitterusername&settings=0,1,2,248,279,ffffff,0,c4c4c4,101010,1,1,336699' type='text/javascript'%3E%3C/script%3E"));</script>

Actually my text editor is not marking $twitterusename inside the script as valid php code. Please help me out.

Try this:

<script type="text/javascript">document.write(unescape("%3Cscript src='http://twitterforweb.com/twitterbox.js?username=<?php echo $twitterusername;?>settings=0,1,2,248,279,ffffff,0,c4c4c4,101010,1,1,336699' type='text/javascript'%3E%3C/script%3E"));</script>

As it's a PHP variable, you need to echo it out with PHP, not javascript.

So you need to replace

$twitterusername

with

<?php echo $twitterusername; ?>

Even though it's inside the <script> tags, it's going to echo out whatever $twitterusername is as long as it's in PHP tags.

If your server supports shortcode, you could use

<?=$twitterusername;?>

making it slightly shorter.

<script type="text/javascript">document.write(unescape("%3Cscript src='http://twitterforweb.com/twitterbox.js?username=<?=$twitterusername;?>settings=0,1,2,248,279,ffffff,0,c4c4c4,101010,1,1,336699' type='text/javascript'%3E%3C/script%3E"));</script>

It is not valid php code, you need to mark it as so using <?php echo $twitterusername; ?>.

Your final code would look like:

<?php $twitterusername = get_option_tree( 'twitter_name', '', 'true' );?>

<script type="text/javascript">document.write(unescape("%3Cscript src='http://twitterforweb.com/twitterbox.js?username=<?php echo $twitterusername; ?>&settings=0,1,2,248,279,ffffff,0,c4c4c4,101010,1,1,336699' type='text/javascript'%3E%3C/script%3E"));</script>

You need to use php tags (<? ?>) to insert variable.

<script type="text/javascript">document.write(unescape("%3Cscript src='http://twitterforweb.com/twitterbox.js?username=<?=$twitterusername?>&settings=0,1,2,248,279,ffffff,0,c4c4c4,101010,1,1,336699' type='text/javascript'%3E%3C/script%3E"));</script>

It's because you are using your PHP variable outside PHP tags.
