Can you combine js and php?

I have a function in my Javascript script that needs to talk with the PHP to get the data in my database. But I'm having a small problem because I start the PHP in the for loop in Javascript, and then inside that for loop I get the data in my database. But the pointer in the for loop inside the PHP code is not working.. I guess the problem is in escaping? Or maybe it's not possible at all.

Here's my code:

(function() {
  var data = [];
  for(var i = 0; i < 25; i++) {
    data[i] = {
       data1: "<a href='<?= $latest[?>i<?=]->file; ?>'><?= $latest[?>i<?=]->title; ?></a>", // The problems
       data2: ....
    };
  };
});

I think you are confused, you are trying to use a variable of javascript in php.

You cannot do this:

<?= $latest[?>i<?=]->file; ?>'

Which expands to:

<?php
   $latest[
?>
 i
<?php
]->file;
?>

how can you possibly know the value of i, if i is a variable generated in the client side?, do not mix the ideas, i is defined in the browser and the php code is on the server.

1.Pass the javascript variable to the URL to another php page.

window.open("<yourPhpScript>.php?jsvariable="+yourJSVariable);

2.Then you can use this variable using $_GET in the php script.

$jsVaribleInPhp=$GET['jsvariable'];
//do some operation
$yourPhpResult;

3.Perform any server side operation in the Php and pass this result.

header("Location:<your starting page>?result=".$yourPhpResult);

4.Redirect back to the page you started from thus passing the result of PHP.

Php and Javascript have different roles in web development. This task can also be performed if there's a php script and js in the same page. But that I leave for the readers to work it out.

Hope this helps!!

Hi,

My javascript is,

var fvisit  = setTimeout(function(){
        $.niftyNoty({
            type: 'dark',
            title: 'Hello',
            message: 'Lorem ipsum dolor sit amet consectetuer <br> adipiscing elit sed diam nonummy nibh.',
            container: 'floating',
            timer: 55000
        });
        clearTimeout(fvisit);
     }, 3000);

PHP script,

<?php echo validation::safeOutputToScreen($Auth->getAccountScreenName()); ?>

I try combine script like below,

var fvisit  = setTimeout(function(){
        $.niftyNoty({
            type: 'dark',
            title: 'Hello <?php echo validation::safeOutputToScreen($Auth->getAccountScreenName()); ?>',
            message: 'Lorem ipsum dolor sit amet consectetuer <br> adipiscing elit sed diam nonummy nibh.',
            container: 'floating',
            timer: 55000
        });
        clearTimeout(fvisit);
     }, 3000);

But get output like,

Hello getAccountScreenName()); ?>

Thanks

You cannot run PHP inside javascript. You can get away with certain things such as having html that invokes javascript functions in PHP variables etc..
