Keep database taken content on a page when entering the url in different browser/tab

I have a website in which i take some content (specified in a form) from a database with php, then json_encode it to javascript code and then place it on the page. Whether i save this content in php session or not when i enter the page url from another tab or browser it doesnt show the content. I think that this is because i dont go through the form and the javascript is executed on the client(aka the variable in which i save the content is empty). My question is how can i show the content with just entering the url of the page, not going through the form. I suppose i should save the content on the server, but how?
Here's the code of the page with the form:
http://hostcode.sourceforge.net/view/2356.
Here's the code of the page on which i show the content:
http://hostcode.sourceforge.net/view/2355

Javascript refresh page automatically

I have an HTML page. Everytime I add new content to the page, the user needs to refresh the page in order to see the new content.
What I want to do is to refresh the page automatically for them regardless of browser.
I tried putting the following but the screen flickers so many times that it does not prove to be useful:
<script type="text/javascript">
location.reload();
</script>

The JavaScript you show there does indeed reload the page. Every single time the page loads, as soon as it reaches that JavaScript. The flickering you're seeing is probably the fact that it in an infinite cycle of reloading. What you need to do is perform an AJAX request to the server to find out if there is new content, and then reload the page if there is. Or, alternatively, use the AJAX to actually update the new content on the page.
