Having a look in the doc, this code works :
$customers = Customers::find();
$numberPage = $this->request->getQuery("page", "int");
$paginator = new Paginator(array(
"data" => $customers,
"limit" => 10,
"page" => $numberPage
));
But this one doesn't work, and I really don't understand why
$customers = Customers::find()->filter(
function ($customer) {
// Return only customers with a valid e-mail
if (filter_var($customer->email, FILTER_VALIDATE_EMAIL)) {
return $customer;
}
}
);
$numberPage = $this->request->getQuery("page", "int");
$paginator = new Paginator(array(
"data" => $customers,
"limit" => 10,
"page" => $numberPage
));
Then, I get an "internal error". Strange, $customers object seems altered.
Any idea ?
By advance, thank you.
Result of Model::find() should be an instance of Phalcon\Mvc\Model\Resultset what is accepted by paginator of Phalcon\Paginator\Adapter\Model.
Result of Resultset::filter() method is an array of model instances, what is not an instance of Resultset. To paginate arrays there is Phalcon\Paginator\Adapter\NativeArray paginator implemented.

The following method is intended to return an array with another array, 'data' and an Object (The result of some eloquent query).
It is however returning an array with two objects in it; $data is somehow being converted to an object with multiple child-objects, rather than being an array of objects. It should be noted that a dd($data) before the return statement reveals that it is indeed an array of objects. I think that somehow the Laravel middleware that handles response is returning this as an object instead...
Any idea how to work around this?
public function getTestData($id) {
$participants = Participant::where('test_id', $id)->with('testRecords')->get();
$finalRecordValue = TestRecord::where('test_id', $id)->orderBy('created_at', 'desc')->first();
$data = [];
foreach ($participants as $participant) {
foreach ($participant->testRecords as $testRecord) {
if (!array_key_exists((int)$testRecord->capture_timestamp, $data)) {
$data[$testRecord->capture_timestamp] = (object)[
'category' => $testRecord->capture_timestamp,
'value' . "_" . $participant->id => $testRecord->score
];
} else {
$data[$testRecord->capture_timestamp]->{"value" . "_" . $participant->id} = $testRecord->score;
}
}
}
return [$data, Auth::user()->tests()->findOrFail($id)];
}
Try this before excuting return sentence or in it:
array_values($data);
if I have an Eloquent Model called Post, and the mysql table has:
integer ID,
string Text
How do I convert this JSon:
{ post: { text: 'my text' } }
To the relevant Post object that, once received in the controller, I can save to the database like this:
public function store(Post $post)
{
$post->save();
}
I'm not looking to build the logic that would do that for me, but for the Laravel way (or could it be that there isn't one? I googled it with no relevant results).
Convert json to array
Hydrate model from array
$data = '{
"unique_id_001":{"name":"John","email":"JD#stackoverflow.com"},
"unique_id_002":{"name":"Ken","email":"Ken#stackoverflow.com"}
}';
$object = (array)json_decode($data);
$collection = \App\User::hydrate($object);
$collection = $collection->flatten(); // get rid of unique_id_XXX
/*
Collection {#236 ▼
#items: array:2 [▼
0 => User {#239 ▶}
1 => User {#240 ▶}
]
}
*/
dd($collection);
fill looks like the method you want. To avoid adding every attribute to your $filled array, which you would need to do if you wanted to use the fill method, you can use the forceFill method.
It accepts an associative array of attributes, so the JSON will have to be decoded, and we'll have to get the inner post key:
$rawJson = "{ post: { text: 'my text' } }";
$decodedAsArray = json_decode($rawJson, true);
$innerPost = $decodedAsArray['post'];
Once we have the decoded data, we can create an instance of the Post eloquent model and call forceFill on it:
$post = new Post();
$post->forceFill($innerPost);
$post->save();
This is similar to doing:
$post = new Post();
foreach ($innerPost as $key => $value) {
$post->$key = $value;
}
$post->save();
Just turn it to array and fill an eloquent
$arr = json_decode($json, true);
$post = new Post;
$post->fill($arr);
It's way simple as like followings:
$json_post = { "post": { "text": "my text" } };
$post = new Post(
json_decode($json_post, true)
);
Now, you can run all eloquent methods on the most $post, ex:
$post->save()
I tested with laravel v7.11.0
Can you try it like this?
public function store($poststuff)
{
$post = new Post;
$post->text = $poststuff['text'];
$post->save();
}
I used Yii 2.
To be clear:
The two tables, content and task, is 1:1 relation, task.content_id =
content.id;
and I referenced
doc.
in view file, I used Gridview to show data.
and I wanna the content is also searchable even it is in another
table.
Maybe the following sql can explain what I want:
SELECT
c.content,
t.publish_status
FROM
content c, task t
WHERE
c.content LIKE '%keywordInContent%' AND
t.publish_status = 1 AND
c.id = t.content_id
ORDER BY
updated_at
LIMIT 20;
Here is my controller code：
public function actionIndex()
{
$searchModel = new TaskSearch;
$dataProvider = $searchModel->search(Yii::$app->getRequest()->get());
return $this->render('index', [
'dataProvider' => $dataProvider,
'searchModel' => $searchModel,
]);
}
and search model code:
public function search($params)
{
$query = Task::find()->trashed(Task::TRASHED_NO);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
if (!($this->load($params) && $this->validate())) {
return $dataProvider;
}
$query->andFilterWhere(['publish_status' => $this->publish_status]);
return $dataProvider;
}
I have settled it by searching like clause before and adding the resulted content_id to searchModel query, code like follow:
if (!empty($this->keyword)) {
$contentIdArr = Content::find()->select('id')->where(['like', 'content', $this->keyword])->column();
if (empty($contentIdArr)) {
$contentIdArr = -1;
}
$query->andFilterWhere(['content_id' => $contentIdArr]);
}
I wonder is there a way to construct the sql I wrote at begin in Yii 2 ?
thanks for help.
Could you try this:
public function search($params)
{
$query = Task::find()->trashed(Task::TRASHED_NO);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
if (!($this->load($params) && $this->validate())) {
return $dataProvider;
}
if(!empty($this->keyword))
$query->leftJoin('content', 'content.id=task.content_id')
->andWhere(['publish_status' => 1])
->andWhere(['LIKE', 'content', $this->keyword])
->orderBy('updated_at');
return $dataProvider;
}
But the updated_at shouldn't be part of the search, I guess. This is more about sorting. Look here for an example.
I think you can do it by first getting Content data and have a relation with Task model.
You can achieve relation by this link. Relation in Content model:
public function getTask()
{
return $this->hasOne(Task::className(), ['content_id' => 'id']);
}
and search query
$searchResult = Content::find()
->select('content, publish_status')
->with('task')
->where(['LIKE', 'content', 'keywordInContent'])
->andWhere(['publish_status' => 1])
->orderBy('updated_at')
->limit(20)
->all();
I think this might help you.
I'm trying to pass an object into the Laravel Excel sheet method but I'm not sure how. I get an undefined variable error - which I realize is because I'm inside a function that doesn't have scope to reach the object.
Ultimately I'm loading up regtypes from one table - attendees from another and creating a sheet for each regtype that contains all attendees of that type.
My code:
public function export()
{
$date = date('Y_m_d');
\Excel::create('CMO_Connect_Attendees_Export_'.$date, function($excel) {
$regtypes = Regtype::all();
foreach ($regtypes as $regtype) {
if( $regtype->attendees(3)->count() ) {
$excel->sheet('Attendees', function($sheet) {
$date = date('Y_m_d');
$attendees = new Attendee;
$atts = Attendee::where('block_id', '=', \Input::get('block_id'))
->where('regtype_id', '=', $regtype->id)
->get();
$sheet->setStyle(array(
'font' => array(
'name' => 'Arial',
'size' => 12,
'bold' => false
)
));
$sheet->loadView('attendees.export', array('atts' => $atts))->with('curdate',$date)->with('regtype_name',$regtype->name);
});
} //endif
} //endforeach
$excel->export('xls');
});
}
As I was writing this up I figured it out, pretty simple I should have known as it's simply a method of a Laravel Facade, so you pass the object as an array like so:
$excel->sheet('Attendees', array('regtype' => $regtype), function($sheet) {
I'm trying to build my first app on CodeIgniter. This is also my first time trying to stick to OOP and MVC as much as possible. It's been going ok so far but now that I'm trying to write my first model I'm having some troubles. Here's the error I'm getting:
A Database Error Occurred
Error Number: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Castledine' at line 3
SELECT * FROM (authors) WHERE author = Earle Castledine
Which, as you'll see below, relates to the following line in my model:
$this->db->get_where('authors', array('author' => $author));
I'm not quite sure why it's throwing the error. Is it because Earle Castledine isn't in quotes? If so, why doesn't CI put them in there? I would doubt that's the issue, rather to think it's my fault, but I'm not sure.
I'm having another issue as well. Neither tags nor authors are getting inserted into their respective tables. Their insert statement is wrapped in a conditional that's supposed to be making sure they don't already exist, but it seems to be failing and the insert never happens. I assume it's failing because the tags aren't getting put in the database and it's down in the author section before it tosses the error. I know how to do this with pure PHP but I'm trying to go about doing it the pure CI ActiveRecord way.
Here's the statement I'm using:
if ($this->db->count_all_results() == 0)
And I'm using that instead of what I'd normally use:
if (mysql_num_rows() == 0)
Am I doing it wrong?
Here are my model and controller (only the functions that matter), commented as best I could.
Model:
function new_book($book, $tags, $authors, $read) {
// Write book details to books table
$this->db->insert('books', $book);
// Write tags to tag table and set junction
foreach ($tags as $tag) {
// Check to see if the tag is already in the 'tags' table
$this->db->get_where('tags', array('tag' => $tag));
// trying to use this like mysql_num_rows()
if ($this->db->count_all_results() == 0) {
// Put it there
$this->db->insert('tags', $tag);
}
// Set the junction
// I only need the id, so...
$this->db->select('id');
// SELECT id FROM tags WHERE tag = $tag
$query = $this->db->get_where('tags', array('tag' => $tag));
// INSERT INTO books_tags (book_id, tag_id) VALUES ($book['isbn'], $query->id)
$this->db->insert('books_tags', array('book_id' => $book['isbn'], 'tag_id' => $query->id));
}
// Write authors to author table and set junction
// Same internal comments apply from tags above
foreach ($authors as $author) {
$this->db->get_where('authors', array('author' => $author));
if ($this->db->count_all_results() == 0) {
$this->db->insert('authors', $author);
}
$this->db->select('id');
$query = $this->db->get_where('authors', array('author' => $author));
$this->db->insert('authors_books', array('book_id' => $book['isbn'], 'author_id' => $query));
}
// If the user checked that they've read the book
if (!empty($read)) {
// Get their user id
$user = $this->ion_auth->get_user();
// INSERT INTO books_users (book_id, tag_id) VALUES ($book['isbn'], $user->id)
$this->db->insert('books_users', array('book_id' => $book['isbn'], 'user_id' => $user->id));
}
}
Controller:
function confirm() {
// Make sure they got here by form result, send 'em packing if not
$submit = $this->input->post('details');
if (empty($submit)) {
redirect('add');
}
// Set up form validation
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<h3 class="error">', ' Also, you’ll need to choose your file again.</h3>');
$this->form_validation->set_rules('isbn','ISBN-10','trim|required|exact_length[10]|alpha_numeric|unique[books.isbn]');
$this->form_validation->set_rules('title','title','required');
$this->form_validation->set_rules('tags','tags','required');
// Set up upload
$config['upload_path'] = './books/';
$config['allowed_types'] = 'pdf|chm';
$this->load->library('upload', $config);
// If they failed validation or couldn't upload the file
if ($this->form_validation->run() == FALSE || $this->upload->do_upload('file') == FALSE) {
// Get the book from Amazon
$bookSearch = new Amazon();
try {
$amazon = $bookSearch->getItemByAsin($this->input->post('isbn'));
} catch (Exception $e) {
echo $e->getMessage();
}
// Send them back to the form
$data['image'] = $amazon->Items->Item->LargeImage->URL;
$data['content'] = 'add/details';
$data['error'] = $this->upload->display_errors('<h3 class="error">','</h3>');
$this->load->view('global/template', $data);
// If they did everything right
} else {
// Get the book from Amazon
$bookSearch = new Amazon();
try {
$amazon = $bookSearch->getItemByAsin($this->input->post('isbn'));
} catch (Exception $e) {
echo $e->getMessage();
}
// Grab the file info
$file = $this->upload->data();
// Prep the data for the books table
$book = array(
'isbn' => $this->input->post('isbn'),
'title' => mysql_real_escape_string($this->input->post('title')),
'date' => $amazon->Items->Item->ItemAttributes->PublicationDate,
'publisher' => mysql_real_escape_string($amazon->Items->Item->ItemAttributes->Publisher),
'pages' => $amazon->Items->Item->ItemAttributes->NumberOfPages,
'review' => mysql_real_escape_string($amazon->Items->Item->EditorialReviews->EditorialReview->Content),
'image' => mysql_real_escape_string($amazon->Items->Item->LargeImage->URL),
'thumb' => mysql_real_escape_string($amazon->Items->Item->SmallImage->URL),
'filename' => $file['file_name']
);
// Get the tags, explode by comma or space
$tags = preg_split("/[\s,]+/", $this->input->post('tags'));
// Get the authors
$authors = array();
foreach ($amazon->Items->Item->ItemAttributes->Author as $author) {
array_push($authors, $author);
}
// Find out whether they've read it
$read = $this->input->post('read');
// Send it up to the database
$this->load->model('add_model', 'add');
$this->add->new_book($book, $tags, $authors, $read);
// For now... Later I'll load a view
echo 'Success';
}
}
Could anyone help shed light on what I'm doing wrong? Thanks much.

Where you are using count_all_results(), I think you mean to use num_rows(). count_all_results() will actually create a SELECT COUNT(*) query.
For debugging your problems...
If you want to test if an insert() worked, use affected_rows(), example:
var_dump($this->db->affected_rows());
At any point you can output what the last query with last_query(), example:
var_dump($this->db->last_query());
You can also turn on the Profiler so you can see all the queries being run, by adding in the controller:
$this->output->enable_profiler(TRUE);
I managed to figure this out on my own. The controller didn't really change, but here's the new model:
function new_book($book, $tags, $authors, $read) {
// Write book details to books table
$this->db->insert('books', $book);
// Write tags to tag table and set junction
foreach ($tags as $tag) {
// Check to see if the tag is already in the 'tags' table
$query = $this->db->get_where('tags', array('tag' => $tag));
// trying to use this like mysql_num_rows()
if ($query->num_rows() == 0) {
// Put it there
$this->db->insert('tags', array('tag' => $tag));
}
// Set the junction
// I only need the id, so...
$this->db->select('id');
// SELECT id FROM tags WHERE tag = $tag
$query = $this->db->get_where('tags', array('tag' => $tag));
$result = $query->row();
// INSERT INTO books_tags (book_id, tag_id) VALUES ($book['isbn'], $query->id)
$this->db->insert('books_tags', array('book_id' => $book['isbn'], 'tag_id' => $result->id));
}
// Write authors to author table and set junction
// Same internal comments apply from tags above
foreach ($authors as $author) {
$query = $this->db->get_where('authors', array('author' => mysql_real_escape_string($author)));
if ($query->num_rows() == 0) {
$this->db->insert('authors', array('author' => mysql_real_escape_string($author)));
}
$this->db->select('id');
$query = $this->db->get_where('authors', array('author' => mysql_real_escape_string($author)));
$result = $query->row();
$this->db->insert('authors_books', array('book_id' => $book['isbn'], 'author_id' => $result->id));
}
// If the user checked that they've read the book
if (!empty($read)) {
// Get their user id
$user = $this->ion_auth->get_user();
// INSERT INTO books_users (book_id, tag_id) VALUES ($book['isbn'], $user->id)
$this->db->insert('books_users', array('book_id' => $book['isbn'], 'user_id' => $user->id));
}
}
