How to output Adsense code in wordpress theme Safely!!

Hi Guys,
1.I need help in correctly or safely outputting user entered Adsense/ads code from options panel to the front end in themes.
2.Is it necessary to avoid inline javascript in backend in options panel also?
Any help will be much appreciated.

if you want to safely output javascript, you need to use esc_js( $code ) as that will escape anything bad that might be injected into the code.

Hi Gareth,
Thanks for the quick reply but that is safe way of entering data in variables, it will stripout the adsense code and make it un usable

no it shouldn’t, it will only escape good javascript, esc_js is a sanitization for removing bad code. WordPress has a lot of esc_ functions to strip out bad code.

This is what is outputted when using esc_js

<script type=‘text/javascript’>\n var googletag = googletag || {};\n googletag.cmd = googletag.cmd || [];\n (function() {\n var gads = document.createElement(‘script’);\n gads.async = true;\n gads.type = ‘text/javascript’;\n var useSSL = ‘https:’ == document.location.protocol;\n gads.src = (useSSL ? ‘https:’ : ‘http:’) +\n ‘//www.googletagservices.com/tag/js/gpt.js’;\n var node = document.getElementsByTagName(‘script’)[0];\n node.parentNode.insertBefore(gads, node);\n })();\n</script>\n

it’s changing line breaks to /n so remove them all beforehand, see if that fixes it…

if esc_js doesn’t work then look at esc_attr, have a look at all the sanitization classes in WP.

Escaping will not work Gareth, I want to know how authors who have recently approved themes circumvent the problem.
Thank you for helping.
