Simple Search: Passing Form Variable to URI Using CodeIgniter

Question

I have a search form on each of my pages. If I use form helper, it defaults to $_POST. I\'d like the search term to show up in the URI:

http://examp         


        

Answer 1

Check out this post on how to enable GET query strings together with segmented urls.

After enabling that you can use the following method to retrieve the additional variables.

// url = http://example.com/search/?q=text
$this->input->get('q');

This is better because you don't need to change the permitted_uri_chars config setting. You may get "The URI you submitted has disallowed characters" error if you simply put anything the user enters in the URI.

Answer 2

I don't know much about CodeIgniter, but it's PHP, so shouldn't $_GET still be available to you? You could format your URL the same way Google does: mysite.com/search?q=KEYWORD and pull the data out with $_GET['q'].

Besides, a search form seems like a bad place to use POST; GET is bookmarkable and doesn't imply that something is changing server-side.

Answer 3

As far as I know, there is no method of accomplishing this with a simple POST. However, you can access the form via Javascript and update the destination. For example:

<form id="myform" onsubmit="return changeurl();" method="POST">
<input id="keyword">
</form>

<script>
function changeurl()
{
    var form = document.getElementById("myform");
    var keyword = document.getElementById("keyword");

    form.action = "http://mysite.com/search/"+escape(keyword.value);

    return true;
}
</script>

Answer 4

There's a better fix if you're dealing with people without JS enabled.

View:

<?php echo form_open('ad/pre_search');?>
   <input type="text" name="keyword" />
</form>

Controller

<?php
    function pre_search()
    {
        redirect('ad/search/.'$this->input->post('keyword'));
    }

    function search()
    {
        // do stuff;
    }
?>

I have used this a lot of times before.

Answer 5

Here is the best solution:

$uri = $_SERVER['REQUEST_URI'];

$pieces = explode("/", $uri);

$uri_3 = $pieces[3];

Thanks erunways!
