I am learning codeigniter these days. I have done a website for my own use a couple of days ago where i have just applied pagination today but it seems there is problem with my url rewriting.
Here is my action inside my controller which grabs list of authors in a category
`public function index() {
$data['main_content'] = "templates/public/audio/author_view";
$data['authors'] = $this->author_model->get_authors();
$this->load->view("templates/public/template",$data);
}`
Here is my function that grabs value from db located inside my author model
`public function get_authors($type = 0) {
$this->db->select("author.name,author.image,author.slug");
$this->db->from("author");
$this->db->join("album","author.id = album.author_id");
$this->db->where("album.mime_type",$type);
$this->db->group_by("author.name");
$query = $this->db->get();
return $query->result();
}`
When i clicked on one of author grabbed it open all albums of selected author. then url looks link www.xyz.com/audio/album-nameHere is my code for this route.
$route['audio/(:any)'] = "audio/view_author_album";
At this stage it works fine. But now today when i applied pagination i found that this route will not do more work for me. I have added pagination in my index action Below you can see my code
public function index() {
$config['base_url'] = "http://localhost/mywebsite/audio/index/";
$config['total_rows'] = $this->author_model->get_total_rows();
$config['per_page'] = 1;
$this->pagination->initialize($config);
$data['main_content'] = "templates/public/audio/author_view";
$data['authors'] = $this->author_model->get_authors($config['per_page'], $this->uri->segment(3));
$this->load->view("templates/public/template",$data);
}
This open the details http://localhost/mysite/audio/index/2
against this url my route rule $route['audio/(:any)/(:any)'] = "audio/view_album_details"; works. It should grab the next page instead of my detail view. And url should be something like http://localhost/mysite/audio/2
I also tried $route['audio/(:num)'] = "audio/;
I will highly appropriate if anyone can help me in solving this problem.
i encounter the same issue and i solve it by using two same router
$route['a-b-c/([a-z0-9-]+)/([0-9]*)'] = "product/category/$1";
$route['a-b-c/([a-z0-9-]+)'] = "product/category/";

I have been looking at other websites and see when you search, primary something like a search term, location and category you will see a pretty url like:
example.com/black-boots/new-york/shoes
instead of what I have now which is something like:
example.com/search-results/search?=black+boots&city=new+york&category=shoes
In my route I could start with something like:
router.get('/search-results/:search/:city/:category', shopController.getSearchResults);
And in the controller I could use req.params.city and so on to get the values from the url but the part that I can't figure out is a good way to get the text input values into the url using a get request.
Using GET by default gives me the 'ugly' looking url.
Basically the part that needs to go into the form
<form method="GET" action="/search-results/search/city/category">
Comments, plus this code sample for a GET request:
const form = document.getElementById('searchform');
form.addEventListener('submit', evt => {
const who = encodeURIComponent(document.getElementById('who').value);
const where = encodeURIComponent(document.getElementById('where').value);
const what = encodeURIComponent(document.getElementById('what').value);
window.location.href = `/${who}/${where}/${what}`;
}
We got the need to display a blog posts page that display X posts - first post is displayed as a header and the rest are in 2 columns. The page has a show more button at the bottom that fetches the next page posts using ajax and adding them at the bottom.
Is it possible to get X+1 items for the subsequent pages?
Any hint, even in code are welcome since we use a sourced version of orchard installation.
So before cluttering the comments above this is my proposed solution.
I think there was a slight misunderstanding about changing the controller action which I'd like to clarify (I hope I understood everything correctly now):
Orchard.Blogs | BlogController | Item Action
public ActionResult Item(int blogId, PagerParameters pagerParameters) {
// This is all original code
Pager pager = new Pager(_siteService.GetSiteSettings(), pagerParameters);
var blogPart = _blogService.Get(blogId, VersionOptions.Published).As<BlogPart>();
if (blogPart == null)
return HttpNotFound();
if (!_services.Authorizer.Authorize(Orchard.Core.Contents.Permissions.ViewContent, blogPart, T("Cannot view content"))) {
return new HttpUnauthorizedResult();
}
// This is the actual change:
// Use the pagerParameters provided, otherwise fall back to the blog settings
pager.PageSize = pagerParameters.PageSize.HasValue ? pager.PageSize : blogPart.PostsPerPage;
// This is all original code again
_feedManager.Register(blogPart, _services.ContentManager.GetItemMetadata(blogPart).DisplayText);
var blogPosts = _blogPostService.Get(blogPart, pager.GetStartIndex(), pager.PageSize) // Your new page size will be used
.Select(b => _services.ContentManager.BuildDisplay(b, "Summary"));
dynamic blog = _services.ContentManager.BuildDisplay(blogPart);
var list = Shape.List();
list.AddRange(blogPosts);
blog.Content.Add(Shape.Parts_Blogs_BlogPost_List(ContentItems: list), "5");
var totalItemCount = _blogPostService.PostCount(blogPart);
blog.Content.Add(Shape.Pager(pager).TotalItemCount(totalItemCount), "Content:after");
return new ShapeResult(this, blog);
}
So the change is very subtle, but this way I would configure the blogs default pageSize to 7 items and for every subsequent Ajax-Request I'd provide a "pageSize"-Parameter with the desired size.
Background
I got a page where I’m showing two list views from two separate lists which both have Custom List as their ListTemplate. They got their separate jslink file cause I don’t want them to look alike.
Problem
The js link file targets both listviews since they use the same Template.
Code
(function () {
var listContext = {};
listContext.Templates = {};
listContext.ListTemplateType = 100;
listContext.Templates.Header = "<div><ul>";
listContext.Templates.Footer = "</ul></div>";
listContext.Templates.Item = LinkTemplate;
SPClientTemplates.TemplateManager.RegisterTemplateOverrides(listContext);
})();
Question
Is there any way to make the js only target a specific list?
Ended up going with Paul Hunts solution that he writes about on myfatblog.co.uk. http://www.myfatblog.co.uk/index.php/2013/09/listview-web-part-issues-with-jslink-and-display-templates-a-solution/
The script ended up looking like this and I pasted it into the jslink function where I define what listContext to override.
// Override the RenderListView once the ClientTemplates.JS has been called
ExecuteOrDelayUntilScriptLoaded(function(){
// Copy and override the existing RenderListView
var oldRenderListView = RenderListView;
RenderListView = function(ctx,webPartID)
{
// Check the title and set the BaseViewId
if (ctx.ListTitle == "List")
ctx.BaseViewID = "list";
//now call the original RenderListView
oldRenderListView(ctx,webPartID);
}
},"ClientTemplates.js");
I am attempting to switch from RouteConfig to Routing Attributes.
I am following along the Pro ASP.NET MVC 5 book from Adam Freeman and I'm trying to convert the following code that handles the paging of clients.
routes.MapRoute(
name: null,
url: "{controller}/Page{page}",
defaults: new { action = "Index", status = (string)null },
constraints: new { page = #"\d+" }
);
This works great! As I go to different URLs, the links look very nice
http://localhost:65534/Client - Default page
http://localhost:65534/Client/Page2 - Second page
Now I've decided to try out Url Attributes and having a bit of problems when it comes to how 'pretty' the links are. All of the links are working fine, but it's the 'routing rewriting' that I am trying to fix.
Here are the important parts of my controller.
[RoutePrefix("Client")]
[Route("{action=index}/{id:int?}")]
public class ClientController : Controller {
[Route("Page{page:int?}")]
public ActionResult Index(string sortOrder, string search = null, int page = 1) {
With the attribute above the Index, going to /Client or to /Client/Page gives me a 404.
Adding a blank route to catch the default page
[Route("Page{page:int?}")]
[Route]
Works for /Client and /Client/Page3, but now the rewriting of the URL is messed up. Clicking on page 3 of the pager gives me a URL of
http://localhost:65534/Client?page=3
which is not what I want. Changing the routing to
[Route("Page{page:int?}")]
[Route("{page=1:int?}")]
Works almost 100%, but the default link for /Client is now
http://localhost:65534/Client/Page
So, I am now asking for help. How can I correctly convert the original MapRoute to the attributes?
Just use:
[Route("", Order = 1)]
[Route("Page{page:int}", Order = 2)]
UPDATE
Plainly and simply, the routing framework is dumb. It doesn't make decisions about which route is the most appropriate, it merely finds a matching route and returns. If you do something like:
Url.Action("Index", "Client", new { page = 1 })
You're expecting the generated URL to be /Client/Page1, but since you have a route where page is essentially optional, it always will choose that route and append anything it can't stuff into the URL as a querystring, i.e. /Client?page=1. The only way to get around this is to actually name the route you want and use that named route to generate the URL. For example:
[Route("", Order = 1)]
[Route("Page{page:int}", Name = "ClientWithPage", Order = 2)]
And then:
Url.RouteUrl("ClientWithPage", new { page = 1 })
Then, you'll get the route you expect because you're directly referencing it.
UPDATE #2
I'm not sure what you mean by "go into PagedList.MVC and add a name property to it". It doesn't require any core changes to the code because PagedList already has support for custom page links. Just change your pager code to something like:
#Html.PagedListPager((IPagedList)ViewBag.OnePageOfItems, page => Url.RouteUrl("ClientWithPage", new { page = page }))
And you'll get the URL style you want. Attribute routing can be a bit more finicky than traditional routing, but I'd hardly call it useless. It's far more flexible than traditional routing, but that flexibility has some costs.
I've created a snippet that pulls data from a databse table and displays it in tabular format. The snippet takes an id as parameter, and this is added to the sql query.
My problem is that if I've got more than 1 snippet call (sometimes need the tabular data for different id's displayed on a page) on the same page, all table data is the same as the last database call that's been made by the last snippet.
What do I need to do to kinda not cache the snippet database calls and have them all display their own content?
I've tried setting the page to no cache-able. Also used the [! !] brackets for the snippet calls, and even used the function_exists() method, but none of them helped.
Please can someone help me?
thanks
Try this at the end of the snippet:
mysql_connect('host', 'user', 'pass');
mysql_select_db('db_name');
You need to specify the connection parameters ofcourse.
It would help to answer if you can post your snippet. I do this with multiple calls on the page without issue, so there is either something wrong inside the snippet, or you need to output to unique placeholder names.
You have encountered a glitch of ModX, and it took me a long time to solve. ModX does a lot of caching by using hashing and apparently, when multiple connections are made from within one page divided over multiple snippets, this erratic behaviour can be seen. This is most likely very unwanted behaviour, it can be solved easily but gives you terrible headache otherways.
One sympton is that $modx->getObject($classname, $id)returns null (often).
The solution is very simple:
either use a static class with a single db instance, or
use $modx->setPlaceholder($instance, $tag);, or a combination.
My solution has been:
class dt__xpdo {
private function __construct() {}
public function __destruct() {
$this->close();
}
static public function db($modx = null) {
if ($modx->getPlaceholder('dt_xpdo') == '') {
$dt_user = 'xxxxxxxxx';
$dt_pw = 'xxxxxxxxx';
$dt_host = 'localhost';
$dt_dbname = 'xxxxxxxxx';
$dt_port = '3306';
$dt_dsn = "mysql:host=$dt_host;dbname=$dt_dbname;port=$dt_port;charset=utf8";
$dt_xpdo = new xPDO($dt_dsn, $dt_user, $dt_pw);
$dt_xpdo->setPackage('mymodel', MODX_CORE_PATH.'components/mymodel/'.'model/', '');
//$modx->log(modX::LOG_LEVEL_DEBUG, 'mymodel.config.php');
//$modx->log(modX::LOG_LEVEL_DEBUG, 'Could not addPackage for mymodel!');
$modx->setPlaceholder('dt_xpdo', $dt_xpdo);
}
return $modx->getPlaceholder('dt_xpdo');
}
}
Now you can use in your code:
require_once 'above.php';
and use something like
$xpdo = dt__xpdo::db($modx);
and continue flawlessly!
