(Apologies for double posting. I posted the same query here - http://forum.joomla.org/viewtopic.php?f=474&t=398025&p=2150391#p2150391
Let me say that Joomla is a wonderful application for web developers/ administrators/ users alike. Now, let me come to my issue.
I use Joomla 1.5.15, and use TinyMCE Editor 2.0. Please check attached images.
I have been trying to put in Google cart/ checkout in my webpage. And, everytime i put in <form action="abdcdedf......" target="_top">, and i preview the code, the button works fine. BUT, after I save it, and run it in a browser (tried in Chrome, Opera, IE 8, Firefox), the button doesn't go anywhere, and when i go back and check the HTML, there is no <form action>, there is only <form tag="_top"> and some more <form> parameters.
I tried using 'no editor', using 'jce', using 'xvalidator', and then 'tinymce 2.0' --> all of them strip/ clean the HTML, which, of course, I deeply detest.
Browsing through the forums here in Joomla, as well Help in Google Checkout, I figured it might be one of the editors, and went through all -- and right now, since i am using TinyMCE2.0 - I modified the settings there too - according to some postings. The editor's settings changed by itself - in prohibited settings. I deleted everything that was there, but after i saved my HTML code, and came back to look at the editor's settings, there is 'applet, iframe, script' there.... Don't know how!! I need it to work asap.
I also checked in with the wiki, as well as the other suggestions here. I did NOT want to hack in to the core, before any other suggestions were made by anybody here.
If someone can help, i would be extremely glad. Thanks a lot, in advance.
