Search result and pagination class

[eluser]djalilk[/eluser]
Hi everybody,

I need to create a search system with a keyword which displays a large result so I have to use pagination.
The problem is: how too keep the keyword variable available for all pagination pages ?
I have tried put it in an URI segment but if someone searches a word with forbdiden characters like ' an error is displayed, the 2nd solution is to put it in a session variable but it is totaly ignored by codeigniter.

Has anyone faced this problem ?

Thank you.

last days i did the search controller with pagination, you have keep you keywords with you url to keep it live, than you url is like is

Code:

http://localhost/ur_site/search/keyword/20

function search($keyword)

pagination config
$config['base_url'] = 'http://localhost/ur_site/search/'.$keyword.'/';
$config['uri_segment'] = 3;

if you calling function than you uri_segment can be 4 well check and accordingly you search will go, im also looking for good solution well its also working fine with me

Thank you for answering.

This solution worked for me but what if the submited keyword contains a forbiden character like "'" ? This is not accepted and will return an error.

any example of the forbidden char please put or have you find any problem.

For exemple if the keyword is "Banque D'a"
The following error is returned:


An Error Was Encountered

The URI you submitted has disallowed characters.

[eluser]umefarooq[/eluser]
then we can do one thing, use php urlencode and urldecode for that, tell where error is coming while search or while pagination,

[eluser]djalilk[/eluser]
This is the url I get when I use urldecode: welcome/search/banque+d'/16/1

And the same error is returned :

The URI you submitted has disallowed characters.


Below the search method I'm using

Code:

function search($keyword = null , $city= null ,$offset = null) {





if( $this->input->post('item') ) {

     $keyword = $this->input->post('item');
     $city = $this->input->post('city_id');


}

$config['base_url'] = site_url().'/welcome/search/'.urlencode($keyword).'/'.$city;
$config['total_rows'] = $this->Place->totalProductBySearch($keyword, $city);
$config['per_page'] = '1';





$this->pagination->initialize($config);
$data['result'] = $this->Place->find(urldecode($keyword), $city , $config['per_page'], $offset);
echo  $this->pagination->create_links();


$data['main'] = 'result';
$data['citys'] = $this->city->getcitysDropDown();
$this->load->vars($data);
$this->load->view('template',$data);

}

You can use my URI-safe base_64 encoding helper. http://ellislab.com/forums/viewthread/107741/. It obfuscates the data somewhat, but it works. I also created an alternate URI syntax library which may also help. http://ellislab.com/forums/viewthread/10...10/#551378

the alternative is to do it how the CI forums do it, which is to store the query if i recall, into a search database along with how many it found and generate a hash for it, then you pass the hash along in the URL.

[eluser]djalilk[/eluser]
Does it mean that every query will be stored in a database ?
