This seems like a simple question but I haven't been able to find the relevant answer!
I'm trying to use render_page for the URL that looks like sensors/edit/20
This was my attempt, but I get the error Unable to load the requested file: sensors/edit/20.php
$this->common->render_page($basics,'sensors/edit/'.$sensorID,$data);
I tried adding $sensorID to the $data array, but then I get the error that there are too few arguments being passed to my function edit($sensorID).
Is there a way to use render_page with a URL that passes an argument?
Here is the render_page function:
public function Render_page($basics=array(),$viewname="",$data=array()){
$CI =& get_instance();
$CI->load->view('template/top',$basics);
$CI->load->view('template/header');
$CI->load->view('template/leftnav');
if(is_array($viewname)){
foreach ($viewname as $view){
$CI->load->view($view,$data);
}
}
else{
$CI->load->view($viewname,$data);
}
$CI->load->view('template/footer');
}
Because the 2nd parameter of function $viewname is NOT an URL, but a name of view file in /application/views/ directory. In this case Ci search 20.php file in /application/views/sensors/edit/ directory which is not exist
Pass an argument in URL using render_page in Codeigniter:
redirect('sensors/edit/' . $sensorID);

I have a url: /feedback?page=1 and in my route (not a controller, just a route method) I have the following method inside a route group (the $userId var is from the group prefix):
Route::prefix('accounts/{userId}/feedback')->group(function() {
Route::get('/', function(Request $request, $userId) {
die(var_Dump($request->query('page')));
});
...
}
This returns null. I have tried input('page') to no success either. What am I blatently doing wrong?
I've also tried dd($_GET) which strangely returns nothing.
With dd($_GET) not working it led me to investigate whether the server was passing the query string... I looked into the nginx config and I wasn't passing $query_string to the index file. So, that's that.
Have to include use Illuminate\Http\Request; in the beginning.
You can use dd($request->query('page')) instead of die(var_dump())
I have a route defined in routes.php similar to:
Route::get('something/{firstId}/{secondId}/{thirdId}/{nthId}', 'SomeController#read')->name('read');
In my controller, I have it setup like this, which works perfectly:
public function read($firstId, $secondId, $thirdId, $nthId, Request $request){
...
}
I don't need $firstId, $secondId, etc for the particular method. I just need the $nthId. Is it possible to setup my controller so I can just grab the nth parameter and simplify my code? For example:
public function read($nthId, Request $request){
...
}
You can set argument list using variadic a preceeding ... there is an interesting caption on php.net arguments page and here is it:
Therefore in your case you would have:
public function read(Request $request, ...$ids){
$id2 = $ids[1]; //here is the second path parameter in /id1/id2/id3/..n
...
}
One thing is that variadic parameters have to be last in the declaration.
Ps: I might not be totally correct about injecting other parameters but at least with the example above, it worked correctly.
I cant figure out what is causing this error. I have checked to see if the parameters are correct and they seem to be. Also if anybody has an alternative way to get all the parameters in the route rather than listing them all please do tell. I can't find another way.
public function savePaymentDetails(Request $request, $code, $message, $mPAN, $type, $exp, $name, $TxnGUID,
$ApprovalCode, $CVVMatch, $GT_MID, $GT_TRANS_ID, $GT_Val_Code, $ProcTxnID,
$session, $card_brand_selected, $CRE_Verbose_Request, $CRESecureID,
$trans_type, $content_template_url, $allowed_types, $order_desc, $sess_id,
$sess_name, $return_url, $total_amt, $submit, $ip_address, $customer_lastname, $customer_firstname)
{
$code2 = $request->get('code');
echo $code2;
echo $code;
}
The route
Route::get('return/{code}/{message}/{mPAN}/{type}/{exp}/{name}/{TxnGUID}/{ApprovalCode}/{CVVMatch}/{GT_MID}/{GT_Trans_Id
}/{GT_Val_Code}/{ProcTxnID}/{session}/{card_brand_selected}/{CRE_Verbose_Request}/{CRESecureID }/{trans_type}/{content_template_url}/{allowed_types}/{order_desc}/{sess_id}/{sess_name}/{return_url}/{total_amt
}/{submit}/{ip_address}/{customer_lastname}/{customer_firstname}', 'PaymentController#savePaymentDetails');
Here are the parameters returned by the URL that I need to get
/return?code=000&message=Success&mPAN=XXXXXXXXXXXX1111&type=Visa&exp=1218&name=test+visa&TxnGUID=6041323& ApprovalCode=VI0151&CVVMatch=M>_MID=672840408068703>_Trans_Id=016142173277748>_Val_Code=AACA&ProcTxnID=6041323&session=e91dd8af53j35k072s0bubjtn7&card_brand_selected=Visa&CRE_Verbose_Request=1&CRESecureID=gt153545888233SB&trans_type=+2&content_template_url=https%3A%2F%2Fexample.com%2Fpublic%2Ftemplate&allowed_types=Visa|MasterCard|American+Express&order_desc=6&sess_id=e91dd8af53j35k072s0bubjtn7&sess_name=session&return_url=https%3A%2F%2Fexample.com%2Fpublic%2Freturn&total_amt=1.51&submit=submit&ip_address=10.108.231.98&customer_lastname=visa&customer_firstname=test
The route rule you define actually match the url like this
code/message/mPAN/type/exp/name/TxnGUID/ApprovalCode/CVVMatch/GT_MID/GT_Val_Code/ProcTxnID/session/card_brand_selected/CRE_Verbose_Request/trans_type/content_template_url/allowed_types/order_desc/sess_id/sess_name/return_url/submit/ip_address/customer_lastname/customer_firstname
instead of
return?code=blab&blablabal=blab
You url dismatch any route you define , so a not found exception was thrown .
If you are trying to get all url parameters you can just write your route like that .
Route::get('return', 'PaymentController#savePaymentDetails');
And get parameters in your controller :
$parameters = $requests->all();
What's more , if you are trying to save something to your database , you'd better use the post method , you can find more When should i use post or get.
I am trying to pass data to a view using the boot method in the AppServiceProvider, and have followed the steps outlined in one of the Laracast fundamentals videos. However, I am getting an error in my controller when trying to use this variable.
In my AppServiceProvider:
public function boot()
{
view()->composer('home', function($view){
$view->with('current', Post::orderBy('created_at', 'desc')->first());
});
}
So this should pass the data to my home view as far as I understand, so that I don't need to keep referencing it in all the methods I have in the controller for that view. I then have a homeController with the following method:
public function index()
{
//Get user
$user = Auth::user();
//OMDB API setup - Get Movie name, remove spaces, add into API request
$movie_one = str_replace(" ", "+", $current->movie_one);
$movie_two = str_replace(" ", "+", $current->movie_two);
return view('home', compact(array('user')));
}
Previously I was adding a variable called current in this method to get an entry from my Post table, but wanted to add it to the AppServiceProvider as I will have to re-declare it in other methods as well. The issue I have is that I try to use the $current object again in this method, but it isn't available to it? I get the following error:
ErrorException in homeController.php line 30:
Undefined variable: current
What can I do here? Can I pass that data from to a controller as well as the home view? Or is that not possible?
the code you written inside the boot method, will only be accessible inside home view, if you want to access the Post object inside controller too, you have to follow this, through this you can access your Post object in controller, as will as view.
app()->singleton('current',function($app){
return Post::orderBy('created_at', 'desc')->first();
});
So in your code, you can access the Post object like this,
$post_obj = App::make('current');
$post_obj->movie_two;
or directly
App::make('current')->movie_two;
Normally I would just use URL GET parameters but CodeIgniter doesn't seem to like them and none of the URL helper functions are designed for them, so I'm trying to do this the 'CodeIgniter way'.
I would like to build a page where the model can accept a number of different URI paramters, none necessarily present, and none having to be in any particular order, much like a regular URL query string with get parameters.
Let's say I have the following url:
http://example.com/site/data/name/joe/
Here not including the controller or the method there would be one parameter:
$params = $this->uri->uri_to_assoc(1);
print_r($params);
// output
array( [name] => [joe] )
If I wanted 'joe' to change to 'ray' I could do this:
echo anchor('name/ray');
Simple enough but what if there are more parameters and the position of the parameters are changing? Like:
http://example.com/site/data/town/losangeles/name/joe/
http://example.com/site/data/age/21/name/joe/town/seattle
Is there a way to just grab the URL and output it with just the 'name' parameter changed?
Edit: As per landons advice I took his script and set it up as a url helper function by creating the file:
application/helpers/MY_url_helper.php
Basically I rewrote the function current_url() to optionally accept an array of parameters that will be substituted into the current URI. If you don't pass the array the function acts as originally designed:
function current_url($vars = NULL)
{
$CI =& get_instance();
if ( ! is_array($vars))
{
return $CI->config->site_url($CI->uri->uri_string());
}
else
{
$start_index = 1;
$params = $CI->uri->uri_to_assoc($start_index);
foreach ($vars as $key => $value)
{
$params[$key] = $value;
}
$new_uri = $CI->uri->assoc_to_uri($params);
return $CI->config->site_url($new_uri);
}
}
It works OK. I think the bottom line is I do not like the 'CodeIgniter Way' and I will be looking at mixing segment based URL's with querystrings or another framework altogether.
You can use the assoc_to_uri() method to get it back to URI format:
<?php
// The segment offset to use for associative data (change me!)
$start_index = 1;
// Parse URI path into associative array
$params = $this->uri->uri_to_assoc($start_index);
// Change the value you want (change me!)
$params['name'] = 'ray';
// Convert back to path format
$new_uri = $this->uri->assoc_to_uri($params);
// Prepend the leading segments back to the URI
for ($i=1; $i<$start_index; $i++)
{
$new_uri = $this->uri->segment($i).'/'.$new_uri;
}
// Output anchor
echo anchor($new_uri);
I'd recommend wrapping this in a helper function of some sort. Happy coding!
Why not use CodeIgniter's built in URI Class? It allows you to select the relevant segments from the URL which you could use to create the anchor. However, unless you created custom routes, it would mean that your methods would need to accept more parameters.
To use the URI Class, you would have the following in your method:
echo anchor($this->uri->segment(3).'/ray');
Assuming /site/data/name are all CodeIgniter specific (/controller/method/parameter)
Now, I think this could be made a lot easier if you were using routes. Your route would look like this:
$route['site/data/name/(:any)'] = 'site/data/$1';
Effictively, your URL can be as detailed and specific as you want it to be, but in your code the function is a lot cleaner and the parameters are quite descriptive. You method would defined like this:
function data($name) { }
To extend your route to accept more parameters, your route for the the example URL "http://example.com/site/data/age/21/name/joe/town/seattle" you supplied would look like this:
$route['site/data/age/(:num)/name/(:any)/town/(:any)'] = 'controller/data/$1/$2/$3';
And your function would look like this:
function data($age, $name, $town) { }
