i try to use ajax-solr and my autocomplete and result work.
But i have problem on first load.
I would like to delete the first request on all index.
Because i would like to see only my searchbar on my page.
I didn't find where is problem.
Thank you
If you followed the ajax-solr Reuters tutorial, then you probably have a Manager.doRequest() call after you initialize the widgets, etc. Just remove that line to not send the first request.

This is a little bit hard to understand even the title I put. Sorry about that I just do not know how to clearly explain this, but I will try...
So for example I have a controller and inside that controller I have a function which return the data in the table of my database. then in the last column of every row, I make view,add,edit,delete options as links. When a user clicks on the add for example, they will redirect to an add page. After they submit the form of the add page. they should be redirected to the first page that return the data from the table. but the problem is, the variables of foreach loop in the first page do not got recognized by laravel anymore. because they do not got processed since the route does not goes to the controller and to the function that return the data instead it goes to add function.
So I want to know is there anyway to solve this? If you could provide sample code, I would appreciate a lot thanks
From your explanation, I believe the code to go back to the original page after adding, editing etc is simply return redirect()->back(). This will take the user back to the previous page. As for data continuity, one approach would be considering using sessions. They save data globally and can be accessed from any controller once saved. To do this, simply save the data with session(['session_name' => $data]) and to retrieve the data use session('session_name'). Let me know if this helps!
If you want ti redirect after something like a login or an activation process you can do it with something like this:
return redirect()->to('login')
You can specify the path from your web.php file as you can see in my example in 'myPath'
As #DerickMasai correctly pointed out it is better to use named routes instead of hard coding the path itself.
Naming a route can work like so:
Route::get('/login', [LoginController::class, 'index'])->name('login');
I want extract a number provided by javascript object in site, but I really don't understand that I am doing.
I tried different versions using alike examples and guidelines in import.io site and other tutorial sites, but I got only 1 of two results: extracted all numbers on given page or nothing at all.
I tried e.g. //[contains(.,"Unikālo apmeklējumu skaits:")]#type ; //[contains(.,"Unikālo apmeklējumu skaits:")] . Most likely it's necessary to add there something else, but I just don't know that.
Link I am interested in to extract from is: https://www.ss.lv/msg/lv/clothes-footwear/womens-clothes/trousers/ikcbb.html and information necessary is a number after text "Unikālo apmeklējumu skaits:" which is given by javascript.
Hopefully someone will be able to help me with this problem.
For someone who is new in web-scraping this should be a hard task, I'll ty to explain it. First of all, the xpath to get to that location could be something like this:
'//td[#class="msg_footer" and contains(text(), "Unik")]'
Now you have that tag (and what it contains), but if you check it doesn't contain the number you need, that content is being dynamically loaded with a javascript, and the javascript is this one:
<script type="text/javascript"><!--
var ss_w='rādīt numuru';
document.write( '<scr'+'ipt id="contacts_js" src="/js/2015-10-27/37863/VHoBGkpqSV8bfwkdTX9AXEpZXCVDlASIQ1ZV3kK.js?t='+new Date()+'"></scr'+'ipt>' );
--></script>
which could be gotten from the response with this xpath:
'//script[contains(text(), "contacts_js")]/text()'
from that string, you should replicate the url that comes in src, so this url for example:
/js/2015-10-27/37863/VHoBGkpqSV8bfwkdTX9AXEpZXCVDlASIQ1ZV3kK.js?t=
and add to the end the current date, as javascript creates it with new Date(). Then you should make a request to that url (adding the previous response domain), so something like:
https://www.ss.lv/js/2015-10-27/37863/VHoBGkpqSV8bfwkdTX9AXEpZXCVDlASIQ1ZV3kK.js?t=Wed%20Oct%2028%202015%2020:56:42%20GMT-0500%20(PET)
check that the date is urlencoded. it should return a response like:
var PHONE_CNT=-1;var PHONE_CNT2=-1;var PHONE_CNT3=-1;var EMAIL_CNT=-1;var SHOW_CNT=22;var PH_c="";var PH_1=0;var PH_2=0;var PH_3=0;
pcc_id=0;PH_1=gpzd("JTg3aCU3QyU1QnolN0MlN0JYcWh6JTVCdCU5NSU4QyU5MnV4ayU5QXElN0IlOTQlNUNweiU5MGtvJTdCJThFJTVF","55937369");
where you can check that the value inside SHOW_CNT is the number you want.
If you want to know how I figured out which request and which script was populating that response tag, well that I did using firebug, searching for SHOW_CNT inside all of the responses that involve calling to your URL, which pointed to the request I specified, and then trying to check who was requesting that.
Hope it helped.
support#import.io are the guys to speak to, they give free advice and help trouble shoot problems just like this all the time.
There are all kinds of tips and tricks you can use... for example import.io provide (an undocumented beta) JavaScript Pre-render service that would likely work for you in this scenario. API publish failures are sometimes caused by timeouts while waiting for sites to render JS, this would fix that.

I've been searching for a day or 2 for an answer to this question, but I haven't found one yet. I've got an external application which is modifying a TSV file (adding data) periodically. I'm using the Basic Line Chart example to display the data and it looks really nice:
Now I want the data to update when the TSV file is updated. I want to be able to set an auto-refresh on the data where it pulls from the tsv file and repopulates the graph without refreshing the entire page.
I tried just wrapping up the current code in a function and calling setInterval on that function, but the data remains the same each time (maybe because it's cached?).
Ideally the solution to this would be a function which can be called to Update whenever I'd like (based on a user event, timer, whatever).
Any ideas, links, or suggestions for alternate ways to accomplish the same goal would be much appreciated!
As a bonus question: I understand D3 may not be the right choice for this sort of Psudo-Real-Time data display. Are there other packages which lend themselves to this sort of thing more? The app generating the data is a C# application (in case that ends up mattering).
Edit: As a supplementary explanation, imagine this example but with the data being read from a file: http://mbostock.github.com/d3/tutorial/bar-2.html
If you are executing an Ajax call to fetch the data from the server and you think caching is a problem, you can try busting the cache by setting the cache parameter in jquery's ajaxSetup to false anywhere in your code:
$.ajaxSetup({cache: false});
From the docs:
If set to false, it will force requested pages not to be cached by the
browser. Note: Setting cache to false will only work correctly with HEAD and
GET requests. It works by appending "_={timestamp}" to the GET parameters. The
parameter is not needed for other types of requests, except in IE8 when a
POST is made to a URL that has already been requested by a GET.
This is my first time getting my hands dirty with CI so I'm getting a little confused.
I'm wanting to accomplish a couple things with my question. First of all, I'd like to always use the default controller without having it to appear in the url. For example, I created a new class named after my site (Example.php) and that works fine. However, if I want to call the search function in my controller I then have to go to example.com/index.php/example/search/.
The second thing I want to accomplish is when I run a search I'll get a nice looking url like so: example.com/search/This+is+a+search (I haven't gotten to removing the index.php portion but I know to use a htaccess). I'm not worried about the actual mechanics of the search, just that I'd like to format the url in this way.
I originally experimented with using a Search class but that found that it doesn't allow me put the search in the url because the second parameter should be a function and not the extra stuff.
Thanks for any help.
In application/config/routes.php file add $route to redirect everything to your controller.
Something like this:
$route['([^\/]+)'] = 'content/index/$1';
$route['([^\/]+)\/([^\/]+)'] = 'content/index/$1/$2';
This will redirect urls like example.com/A and example.com/A/B to a controller named content. Parameters A and B will be passed to method index.
I'm having a little trouble with a CodeIgniter route when there is a query (stuff after the ?) in the URI. I know it is good practice to replace queries with routes in CI, but I'm importing in a premade messageboard that already does everything with queries. This is my route:
$route['messageboard/:any'] = "messageboard/index";
Any in this case refers to a script name. So if it's messageboard/admin.php, I have it load a view that loads my premade messageboard's script "admin.php". It's working just fine if I do messageboard/admin.php. It does fine if I do messageboard/admin.php?. If I put a parameter into the query, however, the route won't correctly send the user to the messageboard controller, and instead sends them to a 404. Does anyone have any ideas on how to make this work? I would be eternally grateful. Thanks!
Okay guys, I solved it. I needed to change three things. The first was mtvee's suggestion, which lets it read query strings. The second one you're going to want to change the $config['permitted_uri_chars'] in the config file to include an equals sign, since it starts off disabled and all query strings will be of the for ?a=34 or something like that. The third is you need to go to $config['uri_protocol'] and change it from AUTO to PATH_INFO. Once I did those, it worked.
I'm sure the syntax is:
$route['messageboard/(:any)'] = "messageboard/index"; //<-- notice brackets
and not
$route['messageboard/:any'] = "messageboard/index";
I believe CI doesn't do GET out of the box. Check out Enabling Query Strings here http://ellislab.com/codeigniter/user-guide/general/urls.html
