Button to fetch user back to their previous URL instead of clicking on the browser Back button

[eluser]tkaw220[/eluser]
Hi,

I would like to implement a "continue shopping button" on shopping cart page to return customer to their previous URL. Any idea how I could achieve this? Using session? cookie? How?

Thanks for the help.

i would figure to use the cache class... just cache the page then once they decide to return to where they where before just call that cached page.

Hi jgetner,

Do you have any sample code using the CI cache class? I am not familiar with that class. Any reference would be great.

Billion thanks. Have a nice day.

Save $_SERVER['HTTP_REFERER'] in the session when a user requests the cart contents or presses on "checkout".

When the "continue shopping" button is pressed, check if you have this session variable, and if so, if it's a URL from your site (to prevent redirects to other sites), and if so, redirect() to it.

Code:

if (isset($this->input->server('HTTP_REFERER')))
{
    $this->session->set_userdata('prev_url', $this->input->server('HTTP_REFERER'));
}
else
{
    $this->session->set_userdata('prev_url', base_url());
}

// when Continue Shopping button clicked.
redirect($this->session->userdata('prev_url'), 'location');

To make sure you're storing a URL from your site:

Code:

if (isset($this->input->server('HTTP_REFERER')) && strpos($this->input->server('HTTP_REFERER'), base_url()) === 0)
{
    ....
}

Many thanks to both of you. Now I have a working function to redirect customers back to their previous location. Again, thank you.

Cheers,
Edwin

tkaw220, Make sure you change my if statement to the way WanWizard stated, I have already updated my code for the change.

Not a bad idea, I've noticed I have to copy&paste; to much...
