PHP - 分页：$ _POST或$ _GET

Question

I'm developing a search system(multiple filters) that uses pagination with php. At first i was using the method POST with the main form. But, using POST i was unable to keep the pagination. Reason: when the user search by name, for example, as he clicks in the next pages the query get lost and return to the first page. To fix this i use GET method instead. But using GET, the url gets the parameters. And the users don't want that.

Example:

http://mysearch.com/search.php?name=joe&id=1

I just want to be

http://mysearch.com/search.php

I tried this workaround:

if(typeof window.history.pushState == 'function') {
        window.history.pushState({}, "Hide", "http://mysearch.com/search.php");
}

But when i hit the "Previous Page/Back" in the browser, the URL with the parameters come back either.

Is there a solution for this? Use GET or POST with pagination and the parameters does not shows in the URL?

You can paginate with $_POST just as easily as with $_GET and without SESSION variables/cookies, you just need to pass the pagination variables as hidden values in your HTML form.

eg - for two buttons, one of which takes you to previous page, and one to next:

//prev button
<form action="paginate.php" method="post">
    <input type="hidden" name="prev" value="0"/> 
    <input type="submit" value="Go to previous page"/>
</form>

//next button
<form action="paginate.php" method="post">
    <input type="hidden" name="next" value="2"/> 
    <input type="submit" value="Go to next page"/>
</form>

//search form
<form action="paginate.php" method="post">
    <input type="hidden" name="prev" value="0"/>         
    <input type="hidden" name="next" value="2"/> 
    <input type="text" name="search" value="User input goes here"/> 
    <input type="submit" value="Search the database"/>
</form>

The disadvantage is that POST will give 'page expired' errors when using the browser back button (but not the HTML buttons), which is not great. For that reason I'd prefer $_GET, and also because you can bookmark $_GET queries, but not $_POST.
