First off I would like to say that I have done ample research on jquery pagination tutorials and scripts and the ones I have tried had worked, but just not the way I wanted them to.
What I am looking for is a jquery+php pagination that has 5 buttons. One for the first page, last page, next page, previous page, and manually enter a page to go to (which would also display the current page). I am new to pagination and have no idea how to integrate or alter current scripts, but I'm willing to learn as long as I can have the 5 buttons stated above and use php mysql queries. Thanks for the help!
UPDATE: I can do this with only php (would have to reload the page) but I do not know how to do this with jquery
UPDATE2: I figured out how to have the user manually input page number, but I still do not know how to do the other for buttons. For the next and previous buttons, I think I need to return the current page, but I have no idea how to do this :/
The trick is you use limit and offset parameters in your mysql query. Depending on what page number of the result you are serving, you can modify the ordered mysql query to fetch the result from that offset. It's pretty simple to work with that after you understand how to paginate in mysql queries.
In order to accomplish this you simply need to enable your application to make an ajax call to fetch the 'more info' results. That ajax call should take two parameters, an OFFSET and a LIMIT. Simply store these values locally in the application (via hidden elements, JS cookies, etc) to reference. Next time the 'more info' button is pressed you increment the OFFSET by the LIMIT and repeat.
NOTE: It's important that your query that is fetching the results is also using an ORDER BY. If you are relying on the server to order the results the same automatically you could potentially repeat results if the data is being updated often.

I have a file which displays the resultset of a query. Now there is an option to compare the individual records (maximum upto 4 simultaneously). Problem is when I switch to next page, the previously selected values for comparison are lost (as the same file loads new records afresh, through pagination algorithm). Is there anyway, I could pass the selected values from the first selection and thereon to the final call(of same page). Technology being used is PHP, MySQL & Javascript. Any help would be highly appreciated. Thanks!
This is a shot in the dark without some sample code or a clear explanation of the pagination, but if you are using a form then you can pass the selections to hidden fields, session variables or some other scoped variable. It appears you are using AJAX, but without the code, I can't give you specifics. If you have full access to the code then a click function on the selection of the elements would allow you to pass the variables via AJAX store them via JAVASCRIPT.
If you can provide a few more details, my answer can be more specific. I would have just asked for clarification but I just joined and don't have the 'reputation' for that yet. ;-)
I'm just looking for some advice in this post.
I am currently using pagination via a $_GET variable in the url. However I am not paginating by first calculating a count and then using a LIMIT clause. Instead I am retrieving all values to paginate, then placing them in an array which is then sliced, so the first 10 items of the array are displayed on the first page, and the next 10 on the second page, etc. There is a reason for this madness.
However, this results in the entire query running every time a user clicks a different page number.
Is it at all possible to instead use jQuery/AJAX, so that I can run the query once, then simply cycle through the array without having to reload the page?
Any help would be greatly appreciated.
Thanks
Yeah if you have to get everything out in your query anyway you might as well divide everything up into pages in one go and put them on your page ready to be hidden/shown. Then your page links/buttons will just need to hide the current page and show the page clicked. Shouldn't be too much work.
I am tying to put some user data from the database using php.
The database contains so many record and i am displaying it using mysql_fetch_row() and this gives me the fields of first row.
Now the problem is a have two buttons namely next and previous. And when a click next the fields in the next row has to be obtained the they should be inserted into page without loading the page once again. I am facing problem with this.
I am using php for server side programming and html, css for client side programming.
I think that no one will give you the answer. Too many to write. You need to read about ajax (this is the technology that will allow you to do some action without page reloading).
You need to write javascript(you can use some library like jquery) function which will open some php page with the data that you want and then update your site.
Here you have some nice tutorial:

I have piece of code which refresh data periodically (after 5 sec.), and put it into a table.
This table has sorting option, and checkbox to select a particular row.
Now problem is when i want to sort or choose a row using checkbox, because of auto refresh it set whole table data in previous position. Means if any data i had sorted will not show sorted and/or checked row will be unchecked again.
Please provide me some suggestion how to handle this issue.
Thanks
Your alternative might be to do an AJAX call to pull the data periodically instead of refreshing the whole page via PHP. That way you'll be able to send the correct parameters to handle the sort towards the logic within PHP.
OR
You can push named parameters/actions within the url for sorting purposes. Then use URL's on the table header and the page reloads with a url of something like:
http://example.com/table/sort:asc
http://example.com/table?sort=asc
And then your logic could appropriately pick the previously selected areas up.
if (isset($_GET['sort'])) {
//Do sorting stuff
}
I am not sure the correct terminology for the process that I am trying to describe. I don't even know which platform is underlying the technique. If you understand my description, please give the link to the site(s) and or the keyword name of the process. I think it is done by AJAX, but I am not certain. I use php as the backend code, I just need to find a way to dynamically display the results. Please give suggestions. I forgot the name of the sites that use this, and my link history expired.
TIA
Description:
The page would have a search form and options. After the user submits, the search is initiated, and the results appear inside the dedicated result area. The page does not refresh, just the info inside the result area.
The display area will show 20 (or whatever) results (lines). There will be next, and previous buttons. If you hit next, the next set of results will display.
I am writing a code that generates 20 results for each display. There is no set number of results, so the results might have a start/first page, but do not have an end page.
Each time the user hits 'next', the program would generate/load new results. It would also store previous results, so that when a user hits 'prev', the previous results can instantly come up.
What techniques/program are theses?
Having recently handled pagination with Code Igniter (php framework), the following links might help you and anyone else out:

Usability is important and AJAX pagination introduces some important questions that need addressing regarding pagination, the following article will give some usability guidelines for displaying results in a table:

Code Igniter Prototype Framework Ajax Pagination:
http://codeigniter.com/wiki/AJAX_Pagination_with_CI_Pagination_Library/
Since we're using jQuery, we chose the following, Codeigniter jQuery framework for AJAX pagination

It is not AJAX for sure.
Nobody uses AJAX for the pagination.
And there are about zillion pagination examples over internet
The only thing is never described in articles is how to persist search options for the other pages.
But it's simple enough: http_build_query() can help you
You need to have a GET/POST form submitted via AJAX which contains the fields in the search term and page number.
If you are going to set the page size to 20 results, page_num=4 will show results from 61-80 results.
Usually search results are GET instead of POST (Ex: See Google search results ) along with the page_number as another attribute and value.
#IVAN .. good to know that the library came helpful..
About that searching option; check the recent commit in github
http://github.com/neotohin/CodeIgniter-Ajax-pagination-Library there is an additional parameter added for searching.
I think the simple code in readme is enough for understanding the mechanism.
You could use datatables
https://datatables.net/
https://datatables.net/examples/data_sources/server_side.html
With this plugin using jquery also you could use server sided page request , you just have to handle the plugin post using Ajax.
post automatically sends row , page offset column, search criteria you just have to provide the json encode return
and the plugin automatically has library in featuring pagination, search sort number of rows per page and the table formatting.
Needed are jquery, and the plugin css and js for this to work
let me know if you understood my explanation.
thanks (=
