Question

This is my php code:

<?php
  $typeid = 65;
  $subledgerid = 'subledger'.$typeid;
  $loadledger = 'loadledgers';
   ?>
   <script type="text/javascript">view_subledger('<?php echo $subledgerid;?>',<?php echo $typeid;?>,'<?php echo $loadledger;?>');</script>

This is not calling the view_subledger().

But when i call something like this it will work fine:

<script type="text/javascript">view_subledger('subledger65',65,'loadledgers');</script>

How can i call this?

Answer 1

Here is the safest way to do this:

<?php

$typeid = 65;
$subledgerid = 'subledger'.$typeid;
$loadledger = 'loadledgers';

?>

<script type="text/javascript">
view_subledger.apply(window, <?php print json_encode(array(
  $typeid,
  $subledgerid,
  $loadledger
)); ?>);
</script>

Which generates following code:

<script type="text/javascript">
view_subledger.apply(window, [65,"subledger65","loadledgers"]);
</script>

json_encode() will ensure that variables are escaped properly and with .apply() method you can pass parameter array to JS function.

Another suggested version:

<?php
$typeid = 65;
$subledgerid = 'subledger'.$typeid;
$loadledger = 'loadledgers';
$param_str = implode(', ', array_map('json_encode', array(
  $typeid,
  $subledgerid,
  $loadledger
)));
?>

<script type="text/javascript">
view_subledger(<?php print $param_str; ?>);
</script>

Generates following:

<script type="text/javascript">
view_subledger(65, "subledger65", "loadledgers");
</script>
