Question

Is there anyway I can use a php variable in the JQuery script?

Example:

• PHP variable: $sr2
• Excerpt of JQuery script (with variable): $('#a2_bottom_$sr2')

How can I make it so the variable is valid in that JQuery part?

Thanks

What you could simply do is use your PHP to echo out the code to initiate a JavaScript variable.

<script type="text/javascript">
<?php

  $phpVar = "foo";
  echo "var phpVariable = '{$phpVar}';";

?>
</script>

Once the PHP code is parsed, and the HTML is sent to the user – all they will see is the result of the PHP echo –

<script type="text/javascript">
  var phpVariable = 'foo';
</script>

Now your phpVariable is available to your JavaScript! So you use it like you would in any other case –

$("div."+phpVariable);

That will retrieve us any <div> element with a foo class –

<div class="foo"></div>
