I need to retrieve session variable data inside an ajax call. Here is my try.
$('#update').click(function(){
var number = $('#num').val();
var curuser = <?php echo $_SESSION['userName'];?>
if( number != '' && number.length==9 )
{
$.ajax({
data:{number:number},
success:function(data){
$('#number_add').val(number);
$('#new_data_Modal').modal('show');
}
});
}
});
Seems like var curuser = <?php echo $_SESSION['userName'];?>
prevents opening my model(new_data_Modal) after button(update) click. When I remove that line it works fine(Model is opening as previous).
But alert("<?php echo $_SESSION['userName'];?>")
is working and it prints the session variable as well.
Can someone show me where I made the wrong?

If this is a string you need to wrap the variable in quotes:
otherwise, when PHP code is executed you will get a syntax error:
You can check the source code of the generate HTML to see what is the output.
NOTE: Your javascript code needs to be a PHP file with a PHP extension, it can be your HTML or JavaScript file. You can use JS file as PHP script in script tag
<script src="code.php"></script>
If you’re outputting JavaScript values from your php script you should use json_encode, that way any data type will work and there is no risk of your code breaking if you data has a quote or new line in it.
