Zabbix 2.0: Getting graph image with cURL, graph ID changes?

[arimbun]

Hi guys,

There was a script written in PHP that I got somewhere off the net. Basically, given a graph ID, what it does is make a curl request to grab a graph image from the Zabbix server. You can then use the image for displaying on your website.

The code looks like this:

/**
     *
     * GraphImgByID v1.1
     *
     * It's free use it however you want.
     * ChangeLog:
     * 1/23/12 - Added width and height to GetGraph Function
     *
     * $author (c) Travis Mathis - [email protected]
     *
     * @param $graphid
     * @param $width
     * @param $height
     * @param $period
     * @return string
     */
    public function get_graph_image_by_id($graphid, $width, $height, $period) {
        //CONFIGURATION
        $z_server = 'http://zabbix.url/zabbix/';
        $z_user   = 'user';
        $z_pass   = 'pass'

        //NON CONFIGUREABLE
        $z_tmp_cookies = "";
        $z_url_index   = $z_server . "index.php";
        $z_url_graph   = $z_server . "chart2.php";
        $z_login_data = "name=" . $z_user . "&password=" . $z_pass . "&enter=Sign in&autologin=1&request=";

        // file names
        $filename_cookie = $z_tmp_cookies . "zabbix_cookie_" . $graphid . ".txt";

        //setup curl
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $z_url_index);
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $z_login_data);
        curl_setopt($ch, CURLOPT_COOKIEJAR, $filename_cookie);
        curl_setopt($ch, CURLOPT_COOKIEFILE, $filename_cookie);

        // login
        curl_exec($ch);
        // get graph
        curl_setopt($ch, CURLOPT_URL, $z_url_graph . "?graphid=" . $graphid . "&width=" . $width . "&height=" . $height . "&period=" . $period);
        $output = curl_exec($ch);
        curl_close($ch);
        // delete cookie
        unlink($filename_cookie);
        return base64_encode($output);
    } 

The problem I am having is that the ID of a graph that I had setup changed recently for unknown reasons. I was able to find out when I inspected the graph image with Firebug - the <img> tag's "src" attribute contains a different graph ID to the one I had hardcoded before.

Is there a way to fix a graph ID to the custom graph that I had setup?

Thank you so much!
