Is there an easier way to get and URL parameters similar to that when appending pagination?
Link
Instead of going #if(Input::has('param1') Input::get('param1') #endif
Thanks
You can always default to something if the parameter is missing
{{ Input::get('param1', 'default value') }}
I actually couldn't find a solution to this after researching (I'm sure there is a way, but couldn't find it) so I just decided to create a quick function, a little arbitrary, but works...
$url = '?';
foreach(Input::all() as $input => $value)
$url .= $input . '=' . $value . '&';

I'm trying to make my test app in multilanguage way.
This question has two correlated questions:
First question:
I followed the second answer in How to create multilingual translated routes in Laravel and this help me having a multilanguage site and the route cached, but I've a question and some misunderstanding.
It's a good practice overwrite an app config as they do int the AppServiceProver.php, making:
Config::set('app.locale_prefix', Request::segment(1));
Isn't better to work with the Session::locale in any case?
Second question:
In my case I've two languages, and in the navbar I want to print just ENG when locale is original language, and ITA when session locale is English.
If I'm in the Italian page, the ENG link in the navbar should point to the same English translated page.
Working with the method used in the other question, I hade many problems caused by the:
Config::set('app.locale_prefix', Request::segment(1));
We overwrite the variable in the config file local_prefix, and every time I switch to English language the locale_prefix will change to 'eng' and this sounds me strange, another thing I did is this:
if ( $lang && in_array($lang, config('app.alt_langs')) ){
return app('url')->route($lang . '_' . $name, $parameters, $absolute);
}
We use the alt_langs where are defined only the alternative languages, and this is a problem cause if I pass the local lang, in my case 'it', like lang parameter, this will not be found cause, from the description, the alt_lang should not contain the locale language and you will be able to get only the translated string.
If I change the:
if ( $lang && in_array($lang, config('app.alt_langs')) ){
return app('url')->route($lang . '_' . $name, $parameters, $absolute);
}
in:
if ( $lang && in_array($lang, config('app.all_langs')) ){
return app('url')->route($lang . '_' . $name, $parameters, $absolute);
}
Now using app.all_langs I'm able to choose which URL you want and in which language I want.
How do I get the translated URL?
In the blade file I need to get the translated URL of the page, and if read the other question, we used the $prefix for caching the routes and giving to the route a new name ->name($prefix.'_home'); in this way I can cache all the route and I can call the routes using blade without prefix {{ route('name') }} but, needing the translated url of the actual page a made this on the top of the view:
#php
$ThisRoute = Route::currentRouteName();
$result = substr($ThisRoute, 0, 2);
if ($result =='it' ){
$routeName = str_replace('it_', '', $ThisRoute);
$url = route($routeName,[],true,'en');
} else {
$routeName = str_replace('en_', '', $ThisRoute);
$url = route($routeName,[],true,'it');
}
#endphp
Doing this I get the actual route name that should be it_home I check if start with it_ or en_, I remove the it_ or en_ prefix and I get the translated URL, now you can use the $url as <a href="{{ $url" }}>text</a> cause if I call the {{ route('page') }} I get the link, with the locale language.
This code is not very good, I know, but I written in 5 minutes, need more implementation, and check, but for the moment is just to play with Laravel.
It's a good way?? How can I do it better (except the blade link retrieving)?? Many solution I found used middleware, but I would like to avoid a link in the navbar like mysite.com/changelang?lang=en
Is a good approach overriding the app.locale_prefix?
First
according to your question, it's a bad practice to save the preferences into .env or session because as soon as the session is finished the saved language will be removed also it's common when you need to store any preferences related to your website such as (Color, Font, Language, ...etc) you must store any of them into the cache.
Second
honestly, your code is a very strange and NOT common way and there are two ways to handle what do you need
First
There is a very helpful and awesome package called mcamara it'll help you too much (I recommend this solution).
Second
you can do it from scratch using the lang folder located in the resource folder and you must create files with the same count of the needed languages then use the keys that you'll define into these files into views and you can prefix your routes with the selected language you can use group method like so
Route::group(['prefix' => 'selected_lang'], function() {
Route::get('first_route', [Controller::class, 'your_method']);
});
or you can add the selected language as a query string like so localhost:8000/your_route?lang=en you can follow this tutorial for more info.
I have a statement like "Animal Association" from the database. I want to get its short form. It means, only the first letter of each word like this "AA". In the blade file, I got the whole statement as follows,
<p>{{ $animal->user->club->name}}</p>
So, how can I get a short form of this name?
Thank You!
If you are using MySQL 8+, then a raw select with REGEXP_REPLACE should work here:
$users = DB::table('animals')
->select(DB::raw("SELECT REGEXP_REPLACE(name, '(\\w)\\w+\\s*', '$1')"))
->get();
This very common problem where we ran into, I can provide you a function that will solve your problem. I am sharing two solutions and you can use any of these solutions.
using function
You can use this function in your model and solve your problem.
public function getNameAbbreviate($string){
$abbreviation = "";
$string = ucwords($string);
$words = explode(" ", "$string");
foreach($words as $word){
$abbreviation .= $word[0];
}
return $abbreviation;
}
There is probably no one-line solution, the solution which I provided is readable and understandable.
using regex
This solution is easy to apply and in case you can't make the first method work then go with this.
<p>{{ preg_split("/\s+/", $animal->user->club->name) }}</p>
using regex we can get a direct solution but I personally don't like it or recommend it.
I use display value or data. In case of a single value use loop, but I know this is a bad habit. How can I solve this? for example I use this:
#foreach($result as $result)
{{$result->data}}
#endforeach
First of all, your code doesn't tell anything, and also you have this code all wrong.
You can't name a pointer as the same name of the array, ($result as $result ???) you will have wrong results or errors.
Also inside the froeach you are referencing a variable that doesn't exists (?).
In my opinion "foreach" is necessary to loop through arrays.
I really don't know what are you trying to do, so that would be great if you expand your question and provide more information.
You can replace that with some code like this:
#if($result)
{{$data}}
#endif
You can try code below see
//example in file ExampleController.php
use App\Posts;
public function showAll(){
$data = Posts::all();
return view('showall',['result'=>$data]);
}
//file web.php
Route::get('/show-all','ExampleController#showAll');
//show-all.blade.php
#foreach($result as $value)
{{$value.title_name}}
#endforeah
The request is simple, however, I cannot find a way to implement it. I have links like:
httр://mysite.com/index.php?lang=EN
httр://mysite.com/index.php?route=add&lang=EN
httр://mysite.com/index.php?route=view&lang=EN
and so on. What I want is to create 301 redirects so that EN could be changed to GB. For example, if a customer opens httр://mysite.com/index.php?route=add&lang=EN, he should be redirected to httр://mysite.com/index.php?route=add&lang=GB.
I have searched for this for days and have failed to find a working solution. Please help.
Does it have to be done in .htaccess? Here's a relatively simple way of doing it in PHP:
<?
if ("EN" == $_GET['lang']) {
$params = $_GET;
$params['lang'] = "GB";
$query_strings = array();
foreach ($params as $key => $value) {
$query_strings[] = $key . "=" . $value;
}
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.mysite.com?" . join($query_strings, "&");
}
Bottom line is that it may be easier to fix this problem on a level where you can isolate each query parameter and look at just the lang parameter and determine whether to do a redirect.
With regular expressions (as you would need to use in .htaccess) it's harder to isolate just the lang part. You would also need one line per language you want to redirect and maintain the list.
Got stuck at some stuff. In short, I need to extract some certain data from a webpage.
Basically, I need to extract /title/tt0118615/ from
Anaconda"
by using preg_match() or whatever other ways. That's a piece of the code from the page which is extracted by the php code below:
<?php
$url = "http://www.imdb.com/find?s=tt&q=Anaconda";
$raw = file_get_contents($url);
echo preg_match ("/^(href=\"\/title\/tt)\"$/", $raw, $data);
echo "data: $data[1]";
?>
I know I'm wrong at the pattern, so that's why I'm posting my question here.
Thanks in advance.
I think this pattern will work in your case:
preg_match("/a href=\"([^\"]*)\"/", $raw, $data);
$data will be an array containing your results, $data[1] is the one you're looking for
$url = "http://www.imdb.com/find?s=tt&q=Anaconda";
$raw = file_get_contents($url);
preg_match_all('%b\.gif\?link=(/title/.*?)\'%i', $raw, $imdbcode, PREG_PATTERN_ORDER);
$imdbcode = $imdbcode[1][0];
echo $imdbcode; #echo's /title/tt0118615/
