How to call a javascript script in single.php header

I asked this question on wordpress forum,seems like noone have any idea of this
I am having to display both ad sense and cpalead javascript in all posts,so while making itself calling cpalead javascript for the header,what should I do with this?

single.php starts with



<?php get_header(); ?>
<?php
global $options;
foreach ($options as $value) {
if (get_settings( $value['id'] ) === FALSE) { $$value['id'] = $value['std']; } else { $$value['id'] = get_settings( $value['id'] ); } }
?>
<div id="container">

<div id="left-div">

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?>

 

<?php if (is_single()) { ?>

Add code here

<?php } ?>

try that in ur header.php

 

No I dont want it to include the script in my main header.But only call it in single.php file as its header and retain the home and other pages without that script.I hope you understood what I meant,thnks in advance

 

when u put that code in your header.php then it will only show when the single.php is called

 

No if I put that Javascript in my header,it will harm my search engine ranking,thats why I cant do that,what I need is to call the header function as a seperate .js file

 

I am not sure about your question. Still I think this

1) in single.php why cant you include the js script like this

<?php
echo "<script type='javascript'>";
include "your js file name with path";
echo "</script>";

?>

PHP:

If you are trying to call the function inside the js file you can do it like this.

<?php
 
echo "<script type='javascript'>functionName();</script>";

?>

PHP:

Hope this helps.
