how do i Call a php function inside of echo function??

I have added an adsense share function to my WPMU/BP site.

I am using the T2 method of adding an adsense unit to show on only the first post on the index page.
found here http://www.tamba2.org.uk/wordpress/adsense/

These two parts are used to define and show adsense only on the first post
1st part

<?php
$postnum = 1;
$showadsense1 = 1;
?> 

Code (markup):

2nd part

<?php if ($postnum == $showadsense1) {
echo '
<script type="text/javascript"><!--
google_ad_client = <?php get_adsense_code(); ?>;
/* xxxxxxxxxxxxxx */
google_ad_slot = "xxxxxxxxx";
google_ad_width = xxx;
google_ad_height = xxx;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
';
} ?>

<?php $postnum++; ?>

Code (markup):

Now inside of the second part you will notice

<?php get_adsense_code(); ?>

Code (markup):

after google_ad_client =. What this is doing is showing as is when i am viewing the page source. I believe it to be because of a function inside of a function.

My question is would anyone know of a fix for this or is this something that doesnt have a fix.

Thank you

 

try

<?php if ($postnum == $showadsense1) {
echo '
<script type="text/javascript"><!--
google_ad_client = '.get_adsense_code().';
/* xxxxxxxxxxxxxx */
google_ad_slot = "xxxxxxxxx";
google_ad_width = xxx;
google_ad_height = xxx;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
';
} ?>

PHP:

 

Thank you very much for the reply.
It now pulls the code correctly but when it does it puts it in a different spot then defined. ie it should be after google_ad_client = but is now above <script type="text/javascript">. It also shows the publisher # on the page. here is a userblog so you can see what it does.

Just for the record, you cant run different Publishers ID's on different google_ad_slots so you will need to use old style google ads or default the ads by removing the line. google_ad_slot = "xxxxxxxxx";


At a glance $postnum++; is posting the number ?

Please post your function code that calls the numbers from wherever they are stored then we can give you the correct variable to use.

 

<?php get_adsense_code(); ?> is the function code that calls for the numbers

$postnum++ is the post number

and thanks for letting me know about adsense, will adjust

 

<?php 
if ($postnum == $showadsense1) {
$adsense_code = get_adsense_code();
echo '
<script type="text/javascript"><!--
google_ad_client = "'.$adsense_code.'";
/* xxxxxxxxxxxxxx */
google_ad_width = xxx;
google_ad_height = xxx;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
';
} ?>

PHP:

and remove <?php $postnum++; ?>

Assuming get_adsense_code() gets a number thats returned ( thats why I asked for the code ) $adsense_code = get_adsense_code(); will activate the function and $adsense_code will echo it to the page.

 

The output works correctly but for some reason it still shows it before <script type="text/javascript"> instead of after google_ad_client =

if i remove <?php $postnum++; ?> its shows adsense on every post instead of just the first.

i have tested removing <?php $postnum++; ?> like you said but the output is the same and adsense is on every post.

current code being used

<?php 
if ($postnum == $showadsense1) {
$adsense_code = get_adsense_code();
echo '
<script type="text/javascript"><!--
google_ad_client = '.$adsense_code.';
/* 336x280, TOPfirstPOST */
google_ad_width = 336;
google_ad_height = 280;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
';
} ?>
<?php $postnum++; ?>

Code (markup):

 

I have fixed this, Thanks for your help everyone!
