I'm struggling to find a way to convert my object to the correct format.
I want to replace a function that we currently use on generating detailed array, as you can see below everything is static.
private function departmentArray($content=[])
{
return [ static::$A_DEPT_ID => $content
, static::$O_DEPT_ID => $content
];
}
A sample result when that runs is this
{"3":{"complete":0,"incomplete":0},"5":{"complete":0,"incomplete":0}}
I converted the method
private function departmentArray($content=[])
{
$depts = d::getAllMainDepartment();
$dept_array = [];
foreach ($depts as $dept) {
$dept_array[] = array($dept->id => $content);
}
return $dept_array;
}
The resulting format looks like this
[{"3":{"complete":0,"incomplete":0}},{"5":{"complete":0,"incomplete":0}}]
How can I maintain the same format on the first version of code?
You don't push into an associative array, you use the new key as an index.
$dept_array[$dept->id] = $content;
Maybe this is an easy question.
I have a variable which save the user id in it.
$user_id = $_REQUEST['user_id'];
and then I have the URL like this :
try
{
$response = $client->delete('admin/user/**USER ID SHOULD HERE**',[
'headers' => ['Authorization' => $_SESSION['login']['apiKey']]
]);
}
I already try to put variable $user_id like this admin/user/$user_id in that URL but nothing happens.'
This is the delete method()
public function delete($url = null, array $options = [])
{
return $this->send($this->createRequest('DELETE', $url, $options));
}
Am I wrote something wrong ?
Thanks :)
PHP variables will not be parsed inside of a single quoted string. You should use "admin/user/$user_id" if you want the variable's value to be used.
So you could write it like this:
$response = $client->delete("admin/user/$user_id",[
Or simply by concatenating the string and user id variable using .:
$response = $client->delete('admin/user/'.$user_id,[
SOLVED
I have route that does a POST route towards store() in the controller.
I'm trying to test if the action is working properly.
Controller:
public function store() {
$d= Input::json()->all();
//May need to check here if authorized
$foo= new Foo;
$d = array();
$d['name'] = $d['name'];
$d['address'] = $d['address'];
$d['nickname'] = $d['nickname'];
if($foo->validate($d))
{
$new_foo= $foo->create($d);
return Response::json(Foo::where('id','=',$new_foo->id)->first(),200);
}
else
{
return Response::json($foo->errors(),400);
}
}
Now I'm trying to test this using a new class called FooTest.php
Here is the function i'm currently trying to do to make the check work:
public function testFooCreation()
{
$jsonString = '{"address": "82828282", "email": "test#gmail.com", "name":"Tester"}';
$json = json_decode($jsonString);
$this->client->request('POST', 'foo');
$this->assertEquals($json, $this->client->getResponse());
}
when I run phpunit in my cmd, I get an error stating that "name" is undefined. I know i'm not actually passing anything to the request so I'm positive that nothing is actually being checked, but my question is how do I actually pass my json strings to check?
Everytime I put the $json inside the client request, it asks for an array, but when I convert my json string to an array, json_decode wants a string.
UPDATE
I was messing around with the passing of input data and I came across this:
$input = [
'name' => 'TESTNAME',
'address' => '299 TESTville',
'nickname' => 't'
];
Input::replace($input);
Auth::shouldReceive('attempt')
->with(array('name' => Input::get('name'),
'address' => Input::get('address'),
'nickname' => Input::get('nickname')))
->once()
->andReturn(true);
$response = $this->call('POST', 'foo', $input);
$content = $response->getContent();
$data = json_decode($response->getContent());
But whenever I run the test, i still get "name:undefined" It's still not passing the input i've created.
$d= Input::json()->all();
The above statement gets Input in $d.
$d = array();
Now the last statement again initialises $d as an empty new array.
So there is no: $['name'] . Hence, Undefined.
I think, that's the problem with the above code.
Hope it helps :)
I was able to pass the input into a POST route from the test.
public function testFooCreation(){
$json = '{"name":"Bar", "address":"FooLand", "nickname":"foobar"}';
$post = $this->action('POST', 'FooController#store', null, array(), array(), array(), $json);
if($this->assertTrue($this->client->getResponse()->isOk()) == true && $this->assertResponseStatus(201)){
echo "Test passed";
}
}
Turns out that in order for me to actually pass input into the controller through test POST, I have to pass it through the 7th parameter.
I hope this helps others.
of course you get an error , just look at your code
$aInputs = Input::json()->all();
//May need to check here if authorized
$foo= new Foo;
$d = array();
$d['name'] = $d['name'];
$d['address'] = $d['address'];
$d['nickname'] = $d['nickname'];
your assigning the array to it self, which is empty
Edit
Thanks for all the input on this, I did find error in my question so modifying now. Sorry for that.
I am trying to figure out how to return the last object in the JSON string I have rendered. The two functions I am working with:
public function revision($return = false)
{
$id = $this->input->post('galleryID');
$data = array('revision_count' => $this->revision->count_revision($id) );
if($return){
return json_encode($data);
}
else {
echo json_encode($data);
}
}
public function last_revision()
{
$allRevisions = json_decode($this->revision(),true);
return end($allRevisions);
}
The issue is that end() returns error stating that 1st parameter should be array.
Thanks for any help on this.
It is important to note here that json_decode returns an instance of stdClass by default. Try using json_decode($jsonstring, true) to return the JSON as a PHP associative array.
However, You haven't included what the $this->revision() method does. Could you possibly show that portion of the code, since that is the function you are getting a return value from?
Edit:
Alright, after we saw the right function in your code, here are a couple of things I would like to say:
You have added a $return parameter to your revision method, but you aren't using it when you need to. You should change $this->revision() to $this->revision(true) in your last_revision method.
If you're going to return data from the revision() method, there's not much of a point in json_encodeing it, just to json_decode the result. Just pass back the raw data array.
Once you have changed both of these things, this should work:
$allRevisions = $this->revision(true); return end($allRevisions['revision_count']);
You can change the edit_function() to:
public function edit_revision($return = false)
{
$galleryID = $this->input->post('galleryID');
$revisionID = $this->input->post('revisionID');
$data = array('revision_images' => $this->revision->get($galleryID, $revisionID) );
if($return)
return json_encode($data);
else
echo json_encode($data);
}
and then:
public function last_revision(true)
{
$allRevisions = json_decode($this->revision());
return end($allRevisions);
}
Maybe you need convert that json output to an php array (json_decode() function), then you could get the last item with array_pop() function:
https://php.net/array_pop
I get a strange error using json_decode(). It decode correctly the data (I saw it using print_r), but when I try to access to info inside the array I get:
Fatal error: Cannot use object of type stdClass as array in
C:\Users\Dail\software\abs.php on line 108
I only tried to do: $result['context'] where $result has the data returned by json_decode()
How can I read values inside this array?
Use the second parameter of json_decode to make it return an array:
$result = json_decode($data, true);
The function json_decode() returns an object by default.
You can access the data like this:
var_dump($result->context);
If you have identifiers like from-date (the hyphen would cause a PHP error when using the above method) you have to write:
var_dump($result->{'from-date'});
If you want an array you can do something like this:
$result = json_decode($json, true);
Or cast the object to an array:
$result = (array) json_decode($json);
You must access it using -> since its an object.
Change your code from:
$result['context'];
To:
$result->context;
Use true as the second parameter to json_decode. This will decode the json into an associative array instead of stdObject instances:
$my_array = json_decode($my_json, true);
See the documentation for more details.
Have same problem today, solved like this:
If you call json_decode($somestring) you will get an Object and you need to access like $object->key , but if u call json_decode($somestring, true) you will get an dictionary and can access like $array['key']
It's not an array, it's an object of type stdClass.
You can access it like this:
echo $oResult->context;
More info here: What is stdClass in PHP?
As the Php Manual say,
print_r — Prints human-readable information about a variable
When we use json_decode();, we get an object of type stdClass as return type.
The arguments, which are to be passed inside of print_r() should either be an array or a string. Hence, we cannot pass an object inside of print_r(). I found 2 ways to deal with this.
Cast the object to array.
This can be achieved as follows.
$a = (array)$object;
By accessing the key of the Object
As mentioned earlier, when you use json_decode(); function, it returns an Object of stdClass. you can access the elements of the object with the help of -> Operator.
$value = $object->key;
One, can also use multiple keys to extract the sub elements incase if the object has nested arrays.
$value = $object->key1->key2->key3...;
Their are other options to print_r() as well, like var_dump(); and var_export();
P.S : Also, If you set the second parameter of the json_decode(); to true, it will automatically convert the object to an array();
Here are some references:
http://php.net/manual/en/function.print-r.php
http://php.net/manual/en/function.var-dump.php
http://php.net/manual/en/function.var-export.php
Try something like this one!
Instead of getting the context like:(this works for getting array index's)
$result['context']
try (this work for getting objects)
$result->context
Other Example is: (if $result has multiple data values)
Array
(
[0] => stdClass Object
(
[id] => 15
[name] => 1 Pc Meal
[context] => 5
[restaurant_id] => 2
[items] =>
[details] => 1 Thigh (or 2 Drums) along with Taters
[nutrition_fact] => {"":""}
[servings] => menu
[availability] => 1
[has_discount] => {"menu":0}
[price] => {"menu":"8.03"}
[discounted_price] => {"menu":""}
[thumbnail] => YPenWSkFZm2BrJT4637o.jpg
[slug] => 1-pc-meal
[created_at] => 1612290600
[updated_at] => 1612463400
)
)
Then try this:
foreach($result as $results)
{
$results->context;
}
To get an array as result from a json string you should set second param as boolean true.
$result = json_decode($json_string, true);
$context = $result['context'];
Otherwise $result will be an std object. but you can access values as object.
$result = json_decode($json_string);
$context = $result->context;
Sometimes when working with API you simply want to keep an object an object. To access the object that has nested objects you could do the following:
We will assume when you print_r the object you might see this:
print_r($response);
stdClass object
(
[status] => success
[message] => Some message from the data
[0] => stdClass object
(
[first] => Robert
[last] => Saylor
[title] => Symfony Developer
)
[1] => stdClass object
(
[country] => USA
)
)
To access the first part of the object:
print $response->{'status'};
And that would output "success"
Now let's key the other parts:
$first = $response->{0}->{'first'};
print "First name: {$first}<br>";
The expected output would be "Robert" with a line break.
You can also re-assign part of the object to another object.
$contact = $response->{0};
print "First Name: " . $contact->{'first'} . "<br>";
The expected output would be "Robert" with a line break.
To access the next key "1" the process is the same.
print "Country: " . $response->{1}->{'country'} . "<br>";
The expected output would be "USA"
Hopefully this will help you understand objects and why we want to keep an object an object. You should not need to convert an object to an array to access its properties.
You can convert stdClass object to array like:
$array = (array)$stdClass;
stdClsss to array
When you try to access it as $result['context'], you treating it as an array, the error it's telling you that you are actually dealing with an object, then you should access it as $result->context
Here is the function signature:
mixed json_decode ( string $json [, bool $assoc = false [, int $depth = 512 [, int $options = 0 ]]] )
When param is false, which is default, it will return an appropriate php type. You fetch the value of that type using object.method paradigm.
When param is true, it will return associative arrays.
It will return NULL on error.
If you want to fetch value through array, set assoc to true.
I got this error out of the blue because my facebook login suddently stopped working (I had also changed hosts) and throwed this error. The fix is really easy
The issue was in this code
$response = (new FacebookRequest(
FacebookSession::newAppSession($this->appId, $this->appSecret),
'GET',
'/oauth/access_token',
$params
))->execute()->getResponse(true);
if (isset($response['access_token'])) { <---- this line gave error
return new FacebookSession($response['access_token']);
}
Basically isset() function expect an array but instead it find an object. The simple solution is to convert PHP object to array using (array) quantifier. The following is the fixed code.
$response = (array) (new FacebookRequest(
FacebookSession::newAppSession($this->appId, $this->appSecret),
'GET',
'/oauth/access_token',
$params
))->execute()->getResponse(true);
Note the use off array() quantifier in first line.
instead of using the brackets use the object operator for example my array based on database object is created like this in a class called DB:
class DB {
private static $_instance = null;
private $_pdo,
$_query,
$_error = false,
$_results,
$_count = 0;
private function __construct() {
try{
$this->_pdo = new PDO('mysql:host=' . Config::get('mysql/host') .';dbname=' . Config::get('mysql/db') , Config::get('mysql/username') ,Config::get('mysql/password') );
} catch(PDOException $e) {
$this->_error = true;
$newsMessage = 'Sorry. Database is off line';
$pagetitle = 'Teknikal Tim - Database Error';
$pagedescription = 'Teknikal Tim Database Error page';
include_once 'dbdown.html.php';
exit;
}
$headerinc = 'header.html.php';
}
public static function getInstance() {
if(!isset(self::$_instance)) {
self::$_instance = new DB();
}
return self::$_instance;
}
public function query($sql, $params = array()) {
$this->_error = false;
if($this->_query = $this->_pdo->prepare($sql)) {
$x = 1;
if(count($params)) {
foreach($params as $param){
$this->_query->bindValue($x, $param);
$x++;
}
}
}
if($this->_query->execute()) {
$this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ);
$this->_count = $this->_query->rowCount();
}
else{
$this->_error = true;
}
return $this;
}
public function action($action, $table, $where = array()) {
if(count($where) ===3) {
$operators = array('=', '>', '<', '>=', '<=');
$field = $where[0];
$operator = $where[1];
$value = $where[2];
if(in_array($operator, $operators)) {
$sql = "{$action} FROM {$table} WHERE {$field} = ?";
if(!$this->query($sql, array($value))->error()) {
return $this;
}
}
}
return false;
}
public function get($table, $where) {
return $this->action('SELECT *', $table, $where);
public function results() {
return $this->_results;
}
public function first() {
return $this->_results[0];
}
public function count() {
return $this->_count;
}
}
to access the information I use this code on the controller script:
<?php
$pagetitle = 'Teknikal Tim - Service Call Reservation';
$pagedescription = 'Teknikal Tim Sevice Call Reservation Page';
require_once $_SERVER['DOCUMENT_ROOT'] .'/core/init.php';
$newsMessage = 'temp message';
$servicecallsdb = DB::getInstance()->get('tt_service_calls', array('UserID',
'=','$_SESSION['UserID']));
if(!$servicecallsdb) {
// $servicecalls[] = array('ID'=>'','ServiceCallDescription'=>'No Service Calls');
} else {
$servicecalls = $servicecallsdb->results();
}
include 'servicecalls.html.php';
?>
then to display the information I check to see if servicecalls has been set and has a count greater than 0 remember it's not an array I am referencing so I access the records with the object operator "->" like this:
<?php include $_SERVER['DOCUMENT_ROOT'] .'/includes/header.html.php';?>
<!--Main content-->
<div id="mainholder"> <!-- div so that page footer can have a minum height from the
header -->
<h1><?php if(isset($pagetitle)) htmlout($pagetitle);?></h1>
<br>
<br>
<article>
<h2></h2>
</article>
<?php
if (isset($servicecalls)) {
if (count ($servicecalls) > 0){
foreach ($servicecalls as $servicecall) {
echo '<a href="/servicecalls/?servicecall=' .$servicecall->ID .'">'
.$servicecall->ServiceCallDescription .'</a>';
}
}else echo 'No service Calls';
}
?>
Raise New Service Call
</div> <!-- Main content end-->
<?php include $_SERVER['DOCUMENT_ROOT'] .'/includes/footer.html.php'; ?>
It is most likely when it tries to access the data with the generic bracket array accessor and not an object operator. Always ensure the variable type is before accessing the data.
While decoding the JSON, the response will be generated as stdObject instances
Rather than calling $result['context'];, access it by $result->context;
If it needs to call as an array itself, decode the JSON by passing the second parameter as true like
json_decode($jsonData, true);
Change it for
$results->fetch_array()
