First, it depends on how you want to do it, the easy way (JS framework) or hard way (built-in javascript functions). I don't know if you have experience with JS, but you need to make javascript send a POST or GET request to a page with the content using the format "/url?post=[...]" which you would process like any other form using PHP. From briefly searching google for "PHP AJAX tutoria"l, I found this. It covers sending the request without using a framework. If you're going to use a framework I suggest either MooTools or jQuery. I prefer Mootools mostly because it's geared more toward programmers and I find the native extensions very useful. Edit: To post when the character count is a set amount, you simple do this (using Mootools): var ta = $('myTextarea'); ta.addEvent('keyup', function() { var length = ta.get('value').length; if(length >= 10) { var value = length.substr(0, 10); // Send POST request } }

Where are you getting the $cnumber variable from? I'm assuming you getting it from the url (/my/url?cnumber=123). In this case, you may need to get the variable from the $_GET superglobal since register_globals may be turned off (and should be left off for security reasons). $cnumber = $_GET['cnumber']; You should also use error_reporting(E_ALL) to check for any missing variables or small errors.

It looks like your problem is you are submitting your form as a POST. You should use GET and in the pagination, do something like this: <a href="path/to/page?keyword=$_GET['keyword']&page=x">Page x</a>

In your query you need to put SQL_CALC_FOUND_ROWS when you use a limit in order to get all of the rows found, like this: SELECT SQL_CALC_FOUND_ROWS ... Note that there is no comma after the SQL_CALC_FOUND_ROWS. After you execute the query, you execute another query: SELECT FOUND_ROWS() That will return all of the results found, which can be used to calculate how many pages there are. Also, if you are going to be searching, I suggest you look into FULLTEXT searching with MySQL. It's quite powerful and easy to do. You'll have to set your content column to index for fulltext searching though. http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html
