Passing PHP variable into JavaScript
javascript, php
Solution
In your PHP file you could set your user as a global varibale:
<script type="text/javascript">
var ptamzzNamespace = {
sessionUser : '<?php echo $_SESSION['user']; ?>'
}
</script>
Include this before including your external JavaScript code.
Then in your JavaScript file you can use it:
$.("#btn').click (
function() {
alert(ptamzzNamespace.sessionUser);
}
)
Additionally: If you're not sure if your session varibale can contain quotes itsself, you can use `addslashes()` to fix this problem:
`<?php echo addslashes($_SESSION['user']); ?>` even if this will maybe produce something you don't really want to display (because it produces a string with slashes) it will help that your code will not fail. (Thanks to Artefacto)
Would this be an option for you?
Problem
I've a PHP session variable, `$_SESSION['user']`, alive throughout the session. In the head section, I've my JavaScript file included, `scripts.js`. How do I pass the session variable into the JavaScript file if I want something like the following. ``` $.("#btn').click ( function() { alert('<?php echo $_SESSION['user']; ?>'); } ) ``` As the `<?php ?>` isn't recognized in the JavaScript file, the code above doesn't work. So I've to put in the PHP file itself, but how do I keep it in the JavaScript file?
