Maybe it's a stupid question so I will not write a lot..
I have an index.php file with two Jquery Mobile pages each has a form passing variables a function with php_self which inserts datas into Mysql tables. Each form has a table with the latest inserted datas next to it. But the first page's form's table was refreshed only, if I used the second page's form, I needed to push the browser's refresh button to see the latest datas.
I was advised to use data-ajax="false" in the form tags. This worked but the sites lost the css formatting because it redirected the pages to a strange address. For example the original address is mysite.com/index.php#page2 with the data-ajax="false" it will be mysite.com//index.php#page2 or similar. I use the latest stable Jquery Mobile with CDN. Thanks for the answers.
