Passing A Php Variable In External Js File

I've read lots of thread on here but I am still unable to get a variable passed from PHP to an external JS file and wondered if someone could assist? In my PHP file I have the foll

Solution 1:

if you want your external javascript to be dynamic you can make it a php file and give the correct header, example:

<scripttype="text/javascript"src="/js/track.php"></script>

track.php

<?php// javascript generator
Header("content-type: application/x-javascript");
?>
document.write('<IFRAMESRC="<?phpecho$company['website'] ?>"WIDTH="300"HEIGHT="400"></IFRAME>');

Solution 2:

PHP file (don't forget echo and quoting):

<scripttype="text/javascript">var pass_this_variable = '<?phpecho$company['website']; ?>';
</script><scripttype="text/javascript"src="/js/track.js"></script>

JS file (use pass_this_variable instead):

document.write('<IFRAMESRC="'+pass_this_variable+'"WIDTH="300"HEIGHT="400"></IFRAME>');

Solution 3:

You should fix this line: var pass_this_variable = <?php echo $company['website']; ?>;

Adding echo and it should work

Solution 4:

JavaScript provides you the functionality of ajax for the purpose of reading the PHP or text files. Why don't you create the HTML iframe inside a PHP file with your variables parsed and then take back the response and "throw" it inside a div.

Solution 5:

The code for your PHP file:

$cmp = $company['website'];
echo'<input type="hidden" id="cmp1" name="cmp1" value="' . $cmp . '" />';

The code for your JavaScript (.js) file to get the PHP file value:

var company = document.getElementById('cmp').value;
