Hello, here is the code I wanna use PHP function in this JavaScript.

money: <?php $kullanici_bilgileri->bakiye ?>

I wrote it like this but that is not working for me.

Answer 1

To print any text in PHP you should use the echo or print function. So this line:

<?php $kullanici_bilgileri->bakiye ?>

Should be:

<?php echo $kullanici_bilgileri->bakiye; ?>

Edit: As far as I know is that you can't pass a PHP string without using the quotes in your javascript code otherwise you will get errors like

Uncaught SyntaxError: Unexpected identifier

So replace:

money: <?php $kullanici_bilgileri->bakiye ?>

With this:

money: '<?php echo $kullanici_bilgileri->bakiye; ?>',

Answer 2

As @Variable pointed out. if you would like to output a string, you will need to add quotes around it.

An alternative to have a proper typecast in JS is using json_encode , example:

{
    ...
    money: <?php echo json_encode($kullanici_bilgileri->bakiye) ?>,
    ...
}

With this approach, you don't need to worry about forgetting the quotes.
