Combine multiple ajax permission calls into one.

Depending on how larger your tables are, and how large the latency between you and the server, the UI speed increases can be quite dramatic.

Add the following function to astpp/assets/js/module_js/generate_grid.js around line 360

function build_buttons_multi(buttons_arr) {
    var jsonObj = []; //declare object
    if (buttons_arr == "") {

    }
    var btn_field = [];
    var button_property = new Array();

    for (var key in btn_arr) {
        if (btn_arr[key] != null)
            btn_field.push(btn_arr[key]);
    }

    var obj = {};
    var post_data = [];
    for (var i = 0; i < btn_field.length; i++) {
        if (btn_field[i] != "") {
            var btn_str = btn_field[i];
            button_property = btn_str.toString().split(',');

            var layout = 'small';

            if (typeof button_property[6] != 'undefined' && button_property[6] != '') {
                layout = button_property[6];
            }

            obj = {
                'button_name': button_property[7],
                'current_url': window.location.href,

        success: function (response) {
            //console.log('result is ', response);
            result = JSON.parse(response);
            //console.log('result is ', result);
            // alert(button_property[0]+'---'+response_trim);
            $.each(result, function(idx, val) {
                //console.log('idx is ',post_data[idx].button_property);
                if (val == 0) {
                    if (post_data[idx].button_property[5] == 'popup') {
                        jsonObj.push({
                            //name: gettext_custom(button_property[0]), 
                            name: post_data[idx].button_property[0],
                            bclass: post_data[idx].button_property[1],
                            iclass: post_data[idx].button_property[2],
                            btn_url: post_data[idx].newURL,

                }
            });
        }
    });
    return jsonObj;
}

Add the following to astpp/application/modules/login/controllers/login.php around like 720

function customer_permission_list_multi()
{
    $postData = $this->input->post()['post_data'];
    if (!isset($postData)) {
        echo '0';
        return;
    }
    foreach ($postData as $k => $button_array) {
        //$button_array = $this->input->post();
        //var_dump($button_array['button_name']);
        $permissioninfo = $this->session->userdata('permissioninfo');
        $currnet_url = $button_array['current_url'];
        $url_explode = explode('/', $currnet_url);
        $module_name = $url_explode[3];
        $sub_module_name = $url_explode[4];
        //var_dump($button_array['button_name']);
        //var_dump($permissioninfo[$module_name][$sub_module_name][$button_array['button_name']]);
        if ((isset($permissioninfo[$module_name][$sub_module_name][$button_array['button_name']]) 
        && $permissioninfo[$module_name][$sub_module_name][$button_array['button_name']] == 0) or $permissioninfo['login_type'] == '-1' or $permissioninfo['login_type'] == '0' or $permissioninfo['login_type'] == '3') {
            //echo 0;
            $perm[$k] = 0;
        } else {
            //echo 1;
            $perm[$k] = 1;
        }
    }
    echo json_encode($perm);
}

Modify the following line in astpp/assets/js/module_js/generate_grid.js in function build_grid() around line 208.

Change

buttons: build_buttons(buttons),

To

buttons: build_buttons_multi(buttons),

Also, for additional speed improvements, remove language translation(?) by changing the following line around 272

Change

custom_display = gettext_custom(collumn_property[0]);

To

custom_display = collumn_property[0];

Add static file caching to nginx

Add the following to /etc/nginx/sites-available/astpp.conf around line 28, below the log entires in the server { section.

# Enable cache for static files
location ~* \.(js|css|png|jpg|jpeg|gif|ico|po)$ {
        expires 2d;
        add_header Cache-Control "public, no-transform";
}

and restart nginx

systemctl restart nginx

I am seeing "astpp.conf" located in /etc/nginx/conf.d/
