I am doing a simple little piece of code to grab a get variable.
$tab = $this->input->get('tab');
But this variable is returning empty. I am calling this in a controller, and in one controller it is working, but another it is not. It is such a small simple piece of code I am not sure what is going wrong.
My url is:
http://localhost:8888/opportunities/?tab=Blood%20Drive
Even when I do something like this:
log_message("INFO", print_r($this->input->get(), true)
The entire get array is empty...

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' => $data]) and to retrieve the data use session('session_name'). Let me know if this helps!
If you want ti redirect after something like a login or an activation process you can do it with something like this:
return redirect()->to('login')
You can specify the path from your web.php file as you can see in my example in 'myPath'
As #DerickMasai correctly pointed out it is better to use named routes instead of hard coding the path itself.
Naming a route can work like so:
Route::get('/login', [LoginController::class, 'index'])->name('login');
I used Codeigniter to build my site, and everything is going peachy, except when it comes to dealing with pagination. Because database queries are driven by data passed from my URL, this is screwing everything up. I'm SURE I'm overlooking something obvious, but this is my issue:
/events/town/venue/event-name
All fine and works as expected; the method takes the parameters from the URL to get the data and deliver it. But my question is - what do I do when I want to paginate my Events page? I.e.
/events/2
/events/3
...etc
As far as my controller, and my routes are concerned, the page number here is considered a town, which it isn't. How do I get around this?
Many thanks
"Test" your town or "page number" uri segment, if it is integer then
you sure know that you are looking for pagination thing, otherwise
"normal" behavior of your controller/method pattern.
using PHPs is_numeric.
A little pseudo code:
if (is_numeric($this->uri->segment(n))) {
//pagination stuff
} else {
//regular behavior
}
In case you are using aplication/config/routes.php consider using _remap() instead (for this certain controller).
or use routes as following:
$route['events/(:num)'] = "events/page/$1"; //pagination "behind the scene" with method "page" (that is not seen by user).
$route['events/town/venue/(:any)'] = "events/town/venue/$1";
I know that in a .phtml file you do it like this for example:
<?php echo $this->helper('derco_core')->getStoreUrl('dcmotosesp')?>
I want to do the same thing inside a static block. Thanks in advance.
There is no 'clean' way of getting an url for a specific store using shortcodes ({{store url}}).
...because the store shortcode handler end like this (see Mage_Core_Model_Email_Template_Filter::storeDirective()):
return Mage::app()->getStore(Mage::getDesign()->getStore())->getUrl($path, $params);
This means that the store cannot be passed as a parameter.
The following might work but it's a bit ugly. The idea is to send the parameter ___store through $_GET telling Magento to switch to a specific store.
TEST LINK
(replace 'store_code_here' with your specific store code).
An other option would be to extend the method mentioned above and allow it to receive a store_code parameter.
I use this Processing Output function _output(), it work very good with me, but in my controller some output like json, image, i wonn't proccessed by this function!!
so,How _output() function works only in specific type of header?
_output, like _resolve is a catch-all (It's in the docs and I've seen it in the code). It will fire every time and there really isn't a way around that. It's sort of the point of those functions, actually.
You do have options, however, in what you'd like to do with the data once you have it, but then you are limited to either putting a private var in your controller (before you call view, you set a flag, $this->_myFlag = 'BITMAP' or something) or parsing output's parameter (that can get expensive fast).
After that, you're stuck out of luck.
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.
