How to set PHP tag $value into a Javascript parameter?

Question

Script I'm using:

if(isset($_GET['cap']) && isset($captions[$_GET['cap']])){
    $cap = $captions[$_GET['cap']];
}

if(isset($cap)){

}

How can I insert the $cap inside a JavaScript parameter?

Example:

tracks: [{
    file: 'http://mylink.com/caption.srt',
    label: 'English',
    kind: 'captions',
    'default': true
}],

Is your JavaScript inside the php file or whether they are separate? — Rohith K N

Do like this:

<?php

if(isset($_GET['cap']) && isset($captions[$_GET['cap']])){
    $cap = $captions[$_GET['cap']];
?>
<script>
   tracks: [{
      file:<?php echo $cap; ?>,
      label: 'English',
      kind: 'captions',
     'default': true
}],

 </script>
<?php
}
?>

You can combine JS and PHP, by keeping JS inside a PHP if statement, it shall work as you expect

OR

You may try this:

 <?php

if(isset($_GET['cap']) && isset($captions[$_GET['cap']])){
    $cap = $captions[$_GET['cap']];

 echo"<script>tracks:file:".$cap.",label: 'English',kind: 'captions','default':true}],</script>"


}
?>

Value "tracks" is inside an echo, I think will not work.

It's working! I did some changes in your script and it's perfect right now, thanks! It wasn't working because I forgot the ".$cap." syntax to call the php function.

This would assign the value into file

tracks: [{
    file: '<b><?= $cap ?></b>',
    label: 'English',
    kind: 'captions',
    'default': true
}],

In your script

 <script>

   var cap = '<?php echo $cap; ?>'
   tracks: [{
      file:cap,
      label: 'English',
      kind: 'captions',
     'default': true
}],

 </script>

Now cap is can be use in your scripts.

How can I insert the $cap onto "file:" instead of link?

Once you share the cap variable in your file cap has value of $cap .You can use it your script!

make sure the js and php scipts are loaded in the same file!
