I have cookie date stored in a serialized array which I would like to access via the Blade template.
If a cookie value is set matching the current field name, then I want to show it. I am currently using the following code, but I'm not sure how to access the array value.
{{{ Cookie::has('myBookingDetails') ? Cookie::get('myBookingDetails') : old('name') }}}
The value of the myBookingDetails cookie looks like this:
a:4:{s:4:"name";s:13:"Joe Bloggs";s:5:"email";s:29:"joe#domain.co.uk";s:5:"phone";s:11:"0777777777";s:3:"reg";s:6:"123456";}
How can I access the "name" value via Blade?
The data is serialized. You need to use unserialize() function to get the data.
$data = unserialize(Cookie::get('myBookingDetails'));
$name = $data['name']
Check for existence before use.
Don't know if previous answer solved your enigma, but I could give some help.
I fought with a similar case. Seems that in template - in laravel 5.1 - I couldn't access directly to cookies:
Cookie::get('cookiename') simply returns null
cookie('cookiename') returns a Symfony\Component\HttpFoundation\Cookie, but $cookie->getValue() returns (again) null.
The good old $_COOKIE['cookiename'] returns the right cookie, so you could simply go with unserialize( $_COOKIE['myBookingDetails'] )['name']; !
PS: It should be better to handle with cookies in controller and pass a normal variable to the view!

I wan to use CI session in a external script and I got following data from database.
__ci_last_regenerate|i:1446535049;ci_UserID|s:1:"2";ci_UserName|s:24:"example#xyz.com";logged_in|b:1;
I have tried unserialize and unserialize(base64_decode($data)) but I am fail yet.
Please help to extract this data.
I got the solution here
So I have used session decode
session_decode('__ci_last_regenerate|i:1446535049;ci_UserID|s:1:"2";ci_UserName|s:24:"example#xyz.com";logged_in|b:1;');
So session decode stored all the encrypted data in normal php session.
Which I can access using: echo $_SESSION['ci_UserID'];
Well guys thanks for the help
If this is a session variable, you can use CodeIgniter's own session library. Consider the following code (in a controller):
$this->load->library('session'); // load the session library
$session_data = $this->session->all_userdata(); // get all session data
print_r($session_data); // print and get the corrresponding variable name, e.g. "item"
$var = $this->session->userdata('item'); // pick one that suits your needs, e.g. item
Sorry, I have read "the external script" only after having posted the code. This obviously only works in the CI framework.
For an external script you may need to have a closer look. The variables are separated by ";" and "|" and then serialized, so this might work (not tested):
$row = explode(';', '__ci_last_regenerate|i:1446535049;ci_UserID|s:1:"2";ci_UserName|s:24:"example#xyz.com";logged_in|b:1;'); // load the database row
$userid = explode('|', $row[1]);
$userid = unserialize($userid[1]); // now $userid holds the value "2"
I have a website where the front page contains a search form with several fields.
When the user performs a search, I make an ajax call to a function in a controller.
Basically, when the user clicks on the submit button, I send an ajax call via post to:
Route::post('/search', 'SearchController#general');
Then, in the SearchController class, in the function general, I store the values received in a session variable which is an object:
Session::get("search")->language = Input::get("language");
Session::get("search")->category = Input::get("category");
//I'm using examples, not the real variables names
After updating the session variable, in fact, right after the code snippet shown above, I create (or override) a cookie storing the session values:
Cookie::queue("mysite_search", json_encode(Session::get("search")));
And after that operation, I perform the search query and send the results, etc.
All that work fine, but I'm not getting back the values in the cookie. Let me explain myself.
As soon as the front page of my website is opened, I perform an action like this:
if (!Session::has("search")) {
//check for a cookie
$search = Cookie::get('mysite_search');
if($search) Session::put("search", json_decode($search));
else {
$search = new stdClass();
$search->language = "any";
$search->category = "any";
Session::put("search", $search);
}
}
That seems to be always failing if($search) is always returning false, and as a result, my session variable search has always its properties language and category populated with the value any. (Again: I'm using examples, not the real variables names).
So, I would like to know what is happening here and how I could achieve what I'm intending to do.
I tried to put Session::put("search", json_decode($search)); right after $search = Cookie::get('mysite_search'); removing all the if else block, and that throws an error (the ajax call returns an error) so the whole thing is failling at some point, when storing the object in the cookie or when retieving it.
Or could also be something else. I don't know. That's why I'm here. Thanks for reading such a long question.
Ok. This is what was going on.
The problem was this:
Cookie::queue("mysite_search", json_encode(Session::get("search")));
Before having it that way I had this:
Cookie::forever("mysite_search", json_encode(Session::get("search")));
But for some reason, that approach with forever wasn't creating any cookie, so I swichted to queue (this is Laravel 4.2). But queue needs a third parameter with the expiration time. So, what was really going on is that the cookie was being deleted after closing the browser (I also have the session.php in app/config folder set to 'lifetime' => 0 and 'expire_on_close' => true which is exactly what I want).
In simple words, I set the expiration time to forever (5 years) this way:
Cookie::queue("mysite_search", json_encode(Session::get("search")), 2592000);
And now it seems to be working fine after testing it.
Is there any way that I can reset some value from the Input on the server side. Let's say, I am getting the value in foo i.e. Input::get('foo') on the server side, but I don't want that in Input. How may I reset that?
Now all I can think of is getting $formData = Input::except('foo') to get all the input values except foo and the processing this $formData instead. But I don't want to change my whole implementation for that, so is there any otherway provided by Laravel?
Was as simple, as the following:
Input::merge(array('foo' => null));
I know that CakePHP params easily extracts values from an URL like this one:
http://www.example.com/tester/retrieve_test/good/1/accepted/active
I need to extract values from an URL like this:
http://www.example.com/tester/retrieve_test?status=200&id=1yOhjvRQBgY
I only need the value from this id:
id=1yOhjvRQBgY
I know that in normal PHP $_GET will retrieve this easally, bhut I cant get it to insert the value into my DB, i used this code:
$html->input('Listing/vt_tour', array('value'=>$_GET["id"], 'type'=>'hidden'))
Any ideas guys?
Use this way
echo $this->params['url']['id'];
it's here on cakephp manual http://book.cakephp.org/1.3/en/The-Manual/Developing-with-CakePHP/Controllers.html#the-parameters-attribute-params
You didn't specify the cake version you are using. please always do so. not mentioning it will get you lots of false answers because lots of things change during versions.
if you are using the latest 2.3.0 for example you can use the newly added query method:
$id = $this->request->query('id'); // clean access using getter method
in your controller.
http://book.cakephp.org/2.0/en/controllers/request-response.html#CakeRequest::query
but the old ways also work:
$id = $this->request->params->url['id']; // property access
$id = $this->request->params[url]['id']; // array access
you cannot use named since
$id = $this->request->params['named']['id'] // WRONG
would require your url to be www.example.com/tester/retrieve_test/good/id:012345.
so the answer of havelock is incorrect
then pass your id on to the form defaults - or in your case directly to the save statement after the form submitted (no need to use a hidden field here).
$this->request->data['Listing']['vt_tour'] = $id;
//save
if you really need/want to pass it on to the form, use the else block of $this->request->is(post):
if ($this->request->is(post)) {
//validate and save here
} else {
$this->request->data['Listing']['vt_tour'] = $id;
}
Alternatively you could also use the so called named parameters
$id = $this->params['named']['id'];
I have a piece of code I can't figure out how it actually works.
Its flow is like this, looks very easy
Get information to display for example $info
Display information using $this->set('columnname', $info);
Is that set function built-in in cakephp? columnname can also be page's content/type. this set will display info in the page. Where is that page source I need to see? For example perhaps it is stored somewhere in some view that has something like <span id=x></span> it then may only need to get the id and replace something inside the span.
Yes set is built-in in cakephp.
You set variables from controller to pass it to view, like in your controller
$this->set("your_info", $info);
Then in view you can access it as:
echo "This is the info set from controller:".$your_info;
//or if its an array, do
print_r($your_info);
Did you mean something like that. Hope it helps
