I want to check segment of particular URL on route and based on value of segment decide it to handle to another route.Somewhat like below:
Route::get('{module}/{seg}', function(){
if (is_numeric((Request::segment(3)) {
return Route::get('{module}/{seg}',Request::segment(2) . 'Controller#index');
}else{
return Route::get('{module}/{seg}',Request::segment(2).'Controller#index' . Request::segment(3));
}
});
I don't think above code works but can anyone suggest a working code for implementing above logic in laravel?
I'd suggest adding it as an optional parameter, and handle differences in the controller. Given your code, it might look like this, for instance:
// route
Route::get('{module}/{seg}/{param?}', 'Controller#index');
// controller
public function index($module, $seg, $param = null)
{
// for dynamic index methods
if (is_numeric($param)) {
$method = 'index' . $param;
return $this->{$method}();
}
// for non-numeric third-segment params, continue here as usual
}

I need to get the request data but i cant get ip, fullUrl and others with all() method (this only print input values), but when i use "dd(request())" this show me all data (i need the data what is printed with dd method, but like a string to save, withour the exception who print this data). Im debbuging my app so i need to save every request data in a log file, something like:
\Log::debug($request)
So,
You can use:
\Log::debug($request->toString());
or alternatively you can use
\Log::debug((string) $request);
The Laravel Request object comes from Illuminate\Http\Request which extends Symfony\Component\HttpFoundation which exposes the following code:
public function __toString()
{
try {
$content = $this->getContent();
} catch (\LogicException $e) {
return trigger_error($e, E_USER_ERROR);
}
$cookieHeader = '';
$cookies = [];
foreach ($this->cookies as $k => $v) {
$cookies[] = $k.'='.$v;
}
if (!empty($cookies)) {
$cookieHeader = 'Cookie: '.implode('; ', $cookies)."\r\n";
}
return
sprintf('%s %s %s', $this->getMethod(), $this->getRequestUri(), $this->server->get('SERVER_PROTOCOL'))."\r\n".
$this->headers.
$cookieHeader."\r\n".
$content;
}
__toString() is considered a magic method in PHP.
The __toString() method allows a class to decide how it will react
when it is treated like a string. For example, what echo $obj; will
print. This method must return a string, as otherwise a fatal
E_RECOVERABLE_ERROR level error is emitted.
You can read more about it in the official documentation.
I highly recommend to store just what you want from request data if you don't need all of them, however for both cases you can take a look at serialize and json_encode
In routes.php I have following route
Route:: get('/crm/hotel/occupant/{id}', array('uses'=>'OccupantController#occupant','as'=>'crm.hotel.occupant'));
for the above route ... if i put the controller like this it's work...but if i remove the $room_id in model calling like
$hotel = new Occupant();
.. i got an error missing argument 1 ....
public function occupant($room_id)
{
$hotel = new Occupant($room_id);
// manage page
return $hotel->occupant($room_id);
}
how to solve it ...
You can make {id} optional.
It is achieved by this:
Route:: get('/crm/hotel/occupant/{id?}', array('uses'=>'OccupantController#occupant', 'as'=>'crm.hotel.occupant'));
as explained by #vinweb you have to add a question mark ? to your id parameter,
Route:: get('/crm/hotel/occupant/{id?}', array('uses'=>'OccupantController#occupant','as'=>'crm.hotel.occupant'));
but you also have to set your variable to a default value (example taken from the official doc,):
Route::get('user/{id}', function ($id) {
return 'User '.$id;
});
So, in your case it would be probably be something like this :
public function occupant($room_id = null)
{
$hotel = new Occupant($room_id);
// manage page
return $hotel->occupant($room_id);
}
I'm trying to craft a route for a controller that will submit some data to a database. My URL is as follows:
http://example.co.uk/posts/5/edit?type=job
I've tried
Route::post('/posts/{id}/edit?type={role}', 'PostsContoller#store');
but am unsure if this will fly?
Don't add parameters in your route:
Route::post('/posts/{id}/edit', 'PostsContoller#store');
In your controller, just check if parameter exist:
$type = Input::has('type') ? Input::get('type') : null;
Don't worry about HTTP verb, as Input access for all verbs (POST,GET,PUT,DELETE...).
Edit
As pointed out by #Antoine, you can simply specify the default value in the get method
$type = Input::get('type', null);
I don't think that this is the right way to do it.
First way
If you change your route to
Route::post('/posts/{id}/edit/{role?}', 'PostsContoller#store');
You will then call the URL: GET posts/42/edit/job.
your store function in PostsController will be:
public function store($id, $role = null)
{
// some code
}
Second way
You can use another route like:
Route::post('/posts/{id}/edit', 'PostsContoller#store');
You will then call the URL: GET posts/42/edit?type=job
And you can get the type in your store function in PostsController:
public function store($id)
{
// $role will be null if type is not in the URL
$role = Input::get('type', null);
// additional code
}
I would personally go for the second way.
I am trying to load a page dynamically based on the database results however I have no idea how to implement this into codeigniter.
I have got a controller:
function history()
{
//here is code that gets all rows in database where uid = myid
}
Now in the view for this controller I would like to have a link for each of these rows that will open say website.com/page/history?fid=myuniquestring however where I am getting is stuck is how exactly I can load up this page and have the controller get the string. And then do a database query and load a different view if the string exsists, and also retrieve that string.
So something like:
function history$somestring()
{
if($somestring){
//I will load a different view and pass $somestring into it
} else {
//here is code that gets all rows in database where uid = myid
}
}
What I don't understand is how I can detect if $somestring is at the end of the url for this controller and then be able to work with it if it exists.
Any help/advice greatly appreciated.
For example, if your url is :
http://base_url/controller/history/1
Say, 1 be the id, then you retrieve the id as follows:
function history(){
if( $this->uri->segment(3) ){ #if you get an id in the third segment of the url
// load your page here
$id = $this->uri->segment(3); #get the id from the url and load the page
}else{
//here is code that gets all rows in database where uid = myid and load the listing view
}
}
You should generate urls like website.com/page/history/myuniquestring and then declare controller action as:
function history($somestring)
{
if($somestring){
//I will load a different view and pass $somestring into it
} else {
//here is code that gets all rows in database where uid = myid
}
}
There are a lot of ways you can just expect this from your URI segments, I'm going to give a very generic example. Below, we have a controller function that takes two optional arguments from the given URI, a string, and an ID:
public function history($string = NULL, $uid = NULL)
{
$viewData = array('uid' => NULL, 'string' => NULL);
$viewName = 'default';
if ($string !== NULL) {
$vieData['string'] = $string;
$viewName = 'test_one';
}
if ($uid !== NULL) {
$viewData['uid'] = $uid;
}
$this->load->view($viewName, $viewData);
}
The actual URL would be something like:
example.com/history/somestring/123
You then know clearly both in your controller and view which, if any were set (perhaps you need to load a model and do a query if a string is passed, etc.
You could also do this in an if / else if / else block if that made more sense, I couldn't quite tell what you were trying to put together from your example. Just be careful to deal with none, one or both values being passed.
The more efficient version of that function is:
public function history($string = NULL, $uid = NULL)
{
if ($string !== NULL):
$viewName = 'test_one';
// load a model? do a query?
else:
$viewName = 'default';
endif;
// Make sure to also deal with neither being set - this is just example code
$this->load->view($viewName, array('string' => $string, 'uid' => $uid));
}
The expanded version just does a simpler job at illustrating how segments work. You can also examine the given URI directly using the CI URI Class (segment() being the most common method). Using that to see if a given segment was passed, you don't have to set default arguments in the controller method.
As I said, a bunch of ways of going about it :)
In my router.php file I added this code.
$route['mission'] = "content/index/mission";
Here as you know content is controller, index is function and mission is parameter to that function.
But when i check it in my browser, it takes me to content/index .
In other words, it is not passing required parameter to index function.
Make sure your recieving the parameters through the function parameters and not using uri segments.
Controller:
// This is incorrect, and will not work
public function index()
{
$param = $this->uri->segment(3); // This wont work
}
// This is correct and will work.
public function index($param = null) // use null to prevent "undefined var error"
{
if($param != null)
{
// The param was passed and do your stuff here
}
}
