Printing PHP to Javascript

Question

I have the following php script which returns a string of numbers with commas separating them:

<?php include "printqueryrows.php"; ?>

returns

 2.00 , 1.00 , 21.16 , 6.75 , 6.00 , 6.25 , 3.00 ,

I have a javascript chart creator that requires the data in the following format:

<script type="text/javascript"> ...
                {
                name: 'London',
                data: [2.00 , 1.00 , 21.16 , 6.75 , 6.00 , 6.25 , 3.00 , ]
              }
</script>

In order to include the results from the php file in the data field (so that it prints out the numbers, separated by commas, I use this script:

<script type="text/javascript"> ...
    data: [<?php include "printqueryrows.php"; ?>]
</script>

However, this is not printing the data. If I do this line individually in another script, the data prints. But it doesn't print when I try to print it into this javascript file. Any suggestions? Thanks!

Correct me if I'm wrong, but you're just putting data: etc without curly brackets? — Daedalus

Does the HTML-File with the javascript-code have the correct file extension? (.php) — Stefan Neubert

Try setting var queryrows = <?php include "printqueryrows.php"; ?>; in a script tag. Then after put either alert(queryrows); or console.log(queryrows) to check the value is being set correctly — Damon

Please be aware that echoing into JavaScript context may make your application vulnerable to XSS attacks if any of the data is user-generated. — FtDRbwLXw6

You need to ensure that the file that contains your Javascript is itself a PHP script - make sure it ends in .php. If you're not sure if it's worked, check the source of the resulting web page. It should not contain <?php anywhere in the browser-side source.

Thanks for the tip. I had some extra <?php in there

Check two things :

Make sure that JS is embedded in a file with .php extension
Make sure that your printqueryrows.php does :

echo "2.00 , 1.00 , 21.16 , 6.75 , 6.00 , 6.25 , 3.00 , ";
