Hello to everyone who is seeing this! I am a Laravel beginner, using Laravel for API-s calls. I cannot find an appropriate solution how to pick up parameters from GET method that looks like this:
http://localhost:8000/api/products/searchv2/cat=category1&cat=category2
Now I want to receive in my Laravel controller this array
$categories = ["category1", "category2"]
I think the solution is very easy, but due to minimal experience, I cannot find the right answer on the internet or Laravel documentation. Thanks to everyone who tried to help me!
According to this answer, you can use the [] syntax like you would with form fields to create an array. So in your case, the URL would be:
http://localhost:8000/api/products/searchv2/?cat[]=category1&cat[]=category2
And $_GET['cat'] should return an array, so in theory $request->get('cat') would also return an array.
Using Commas
Another way would be to make use of commas, e.g.:
?cat=category1,category2,category3
You could then use explode:
$categories = explode($request->get('cat'));

Laravel pagination trouble with offset
Investigating into my code, I found that when a random alike parameter is given through a route, it will do an like query or I don't know, but it will still work as it will get the first part of the parameter:
The route I'm trying to "ensure" goes like this:
Route::get('/videos/cats/{race_id}/{cat_id}, [App\Http\Controllers\MeowController::class, 'getCatVideo']);
Can someone help me to get that exact parameter as integer, or prevent a route from working if the parameter is not exactly the given one?
Thank you in advance.
Parameters are required by default.
To validate parameter:
Route::get('/videos/cats/{race_id}/{cat_id}, [App\Http\Controllers\MeowController::class, 'getCatVideo'])
->where('race_id', '\d+')
->where('cat_id', '\d+');

I have a page that list apartments depending on book dates like this
mypage.com/finder?date-from=2011-03-04&date-to=2011-03-12
Everything is right, I am getting the date-from and date-get from the url and searching the database with those values. The problem is when I paginate and I click to go to another page the url changes to.
mypage.com/finder?page=9
and get an error Value must be provided
The correct url must be
mypage.com/finder?date-from=2011-03-04&date-to=2011-03-12&page=9
I am using paginate at the controller and $searchResult->links(); to generate the links
What can I do pass the date values from page to page so the pagination works?
Thanks
If you want to tack on existing query string data, use this:
$searchResult->appends(array(
'date-from' => Input::get('date-from'),
'date-to' => Input::get('date-to'),
));
Read the docs: Appending To Pagination Links.
You can shorten that a little:
$searchResult->appends( Input::only('data-from', 'date-to') );
which ends up being the same thing.
you can do this using the 'appends' feature. There are examples in the documentation: http://laravel.com/docs/pagination
I am struggling to understand something that I am sure one of you will be able to easily explain. I am somewhat new to MVC so please bear with me.
I have created a controller that handles all of the work involved with connecting to the Twitter API and processing the returned JSON into HTML.
Route::get('/about', 'TwitterController#getTweets');
I then use:
return View::make('templates.about', array('twitter_html' => $twitter_html ))
Within my controller to pass the generated HTML to my view and everything works well.
My issue is that I have multiple pages that I use to display a different Twitter user's tweets on each page. What I would like to do is pass my controller an array of values (twitter handles) which it would then use in the API call. What I do not want to have to do is have a different Controller for each user group. If I set $twitter_user_ids within my Controller I can use that array to pull the tweets, but I want to set the array and pass it into the Controller somehow. I would think there would be something like
Route::get('/about', 'TwitterController#getTweets('twitter_id')');
But that last doesn't work.
I believe that my issue is related to variable scope somehow, but I could be way off.
Am I going down the wrong track here? How do I pass my Controllers different sets of data to produce different results?
EDIT - More Info
Markus suggested using Route Parameters, but I'm not sure that will work with what I am going for. Here is my specific use case.
I have an about page that will pull my tweets from Twitters API and display them on the page.
I also have a "Tweets" page that will pull the most recent tweets from several developers accounts and display them.
In both cases I have $twitter_user_ids = array() with different values in the array.
The controller that I have built takes that array of usernames and accesses the API and generates HTML which is passed to my view.
Because I am working with an array (the second of which is a large array), I don't think that Route Parameters will work.
Thanks again for the help. I couldn't do it without you all!
First of all, here's a quick tip:
Instead of
return View::make('templates.about', array('twitter_html' => $twitter_html ))
...use
return View::make('templates.about', compact('twitter_html'))
This creates the $twitter_html automatically for you. Check it out in the PHP Manual.
Now to your problem:
You did the route part wrong. Try:
Route::get('/about/{twitter_id}', 'TwitterController#getTweets');
This passes the twitter_id param to your getTweets function.

I am trying to build a Search with Pagination in Codeigniter and would love some help with it.
So far, I've realized that I can not use BOTH url segments and query strings together. Using only query strings produces very ugly URLs.
I understand that Codeigniter destroys the GET and I'm trying to put it back in. Ergo... if I place this in the constructor of the search controller, will my problems be solved?
parse_str(substr(strrchr($_SERVER['REQUEST_URI'], "?"), 1), $_GET);
As in, if it works for me, is there anything I need to be aware of security wise?
So far, I've realized that I can not use BOTH url segments and query strings together.
Sure you can. Try this in your config:
$config['uri_protocol'] = "PATH_INFO";
That should get things started. Now, since CI abandons and empties the $_GET variable, you need to repopulate it like this:
parse_str($_SERVER['QUERY_STRING'],$_GET);
Now the only real concern here is that, if you have global XSS filtering on, you should know that you just manually parsed the query string into the global $_GET variable. This means you haven't passed it through any XSS filters. In CI 1.x you can access the filter through the input library like this:
$myvar = $this->input->xss_clean($_GET['myvar']);
In CI 2.x you do it through the security library like this:
$myvar = $this->security->xss_clean($_GET['myvar']);
Of course, it goes without saying that you can extend the Controller class to have a get() method that does all this automatically such that you can do this:
$myvar = $this->get('myvar');
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
