Question

I decided that I would like to track the searches that users are making on my site, so I created a MySQL table called ‘Searches’ with a few simple fields, and a model (class) to facilitate the insertion and management of the saved searches.

The model function that saves the search is:

public function create() {
    $q = $this->db->query("INSERT INTO 
                                `searches` (
                                    `section`,
                                    `keywords`,
                                    `results`,
                                    `location`,
                                    `date`
                                ) VALUES (
                                    %s, 
                                    %s,
                                    %s,
                                    %s,
                                    %s
                                )",
                                $this->section,
                                $this->keywords,
                                $this->results,
                                $this->location,
                                date('Y-m-d G:i:s'));
    $this->id = $this->db->last_insert($q);
}

…and in my controller, when the page is loaded I go:

    /* lets save the search if there is one */
    if(isset($_GET['q'])) {
        $search = $this->load->model('Searches_Single',null);
        $search->set('section','sale');
        $search->set('keywords',$_GET['q']);
        $search->set('results',$grand_total);
        $search->set('location',$this->location->id);
        $search->create();
        unset($search);
    }

What is baffling me is that 1-4 duplicate rows are often being inserted instead of the just 1 that I expect.

There are no loops, no redirecting…just a very simple pageload. Frankly, I believe this happened to me the last time I attempted this.

UPDATE

This does not happen in my local development environment…only in production (scary). Both share the exact same code…could this be a server thing?

UPDATE NUMBER 2
I am finding that this seems to be happening on page opening and closing. AKA – I check the time the page opens, and the script logs a search then…and then I check the time the page finishes loading, and the script seems to be logging a search there as well…

GAHHH

Answer 1

i determined the problem is that google robots that follow a person to the page to determine which google ad to display are triggering the second pageload and therefore creating a mirrored db insertion. sometimes multiple times on a single page load.

sigh. cmon google.
