在页面上获取请求删除POST信息

Question

I have a page called test_photo.php, which people get directed to from a form after doing a POST request

<form id="search_photos" action="test_photo.php" method="post">
    <select name="photographer" id="photographer">
        <option selected="selected" value="x">Any Photographer</option>
    </select>

    <--Removed for clarity sake -->

    <input name="Submit" value="Search Now &gt;" id="Submit" type="submit">
</form>

on the page that we post to (test_photo.php) we have pagination to help break up the huge amount of data that gets displayed. This is handled by a GET request the url may look something like http://foobar.com/xpath/test_photo.php?page=0.

The problem is that whenever someone perform a get request on the page the POST data disappears. Does anyone know any way in which we can solve this.

Answer 1

Okey, trying to rule out the obvious here.

You are mixing GET and POST in a way that is incorrect. You should only address POST if you have a form with values you don't want exposed and those values are no longer needed after submitting (like logging in). Here you have values that you carry on to the next page etc.

This will never work because if you post a form, the POST-values are only available right after you submitted the form. If you try to do a clean refresh (not reposting the form), you will see that the values are gone.

What you should do it posting the form as POST and then building a query of GET-parameters.

Like

page.php?page=1&photographer=1&location=3

This is a correct way to address filters. Just look at how Google is storing the current search-query (google.com?q=your search). The rule is "values needed across different pages"? Just GET. This will also make it possible for people to bookmark searches or send them to other people with all the filters applied.
