I have been experimenting with ATK4 for a while now and it's just wonderful!
Migrating to 4.2 I came across a problem with Forms updated and not returning the inserted id.
Here is an example:
class page_kids_new extends Page {
function init() {
parent::init();
$this -> add('H1') -> set('New Kid');
$f = $this -> add('Form');
$f -> setModel('Kid');
$f -> addSubmit('Opslaan');
if ($f -> isSubmitted()) {
$id = $f -> update();
$js = $this -> js() -> univ() -> successMessage('Record Saved # ' . $id);
$js -> execute();
}
}
}
The data saves nicely in the database (new record).
For some reason it's returning the Form Object. Output to browser is: Record Saved # Object Form(boaadmin_kids_new_form)
Hope someone can help. Thanks in advance.
Probably the behaviour is changed... Need to ask Romans about this! ;) Have you tried $id = $f->get('id'); AFTER the update?

im quite new in laravel framework, and im from codeigniter.
I would like to add new key and value from database
static function m_get_promotion_banner(){
$query = DB::table("promotion_banner")
->select('promotion_banner_id','promotion_link','about_promotion')
->where('promotion_active','1')
->get();
if($query != null){
foreach ($query as $key => $row){
$query[$key]['promotion_image'] = URL::to('home/image/banner/'.$row['promotion_banner_id']);
}
}
return $query;
}
that code was just changed from codeigniter to laravel, since in codeigniter there are no problem in passing a new key and value in foreach statement
but when i tried it in laravel i got this following error :
Indirect modification of overloaded element of Illuminate\Support\Collection has no effect
at HandleExceptions->handleError(8, 'Indirect modification of overloaded element of Illuminate\Support\Collection has no effect', 'C:\xampp\htdocs\laravel-site\application\app\models\main\Main_home_m.php', 653, array('query' => object(Collection), 'row' => array('promotion_banner_id' => 1, 'promotion_link' => 'http://localhost/deal/home/voucher', 'about_promotion' => ''), 'key' => 0))
please guide me how to fix this
thank you (:
The result of a Laravel query will always be a Collection. To add a property to all the objects in this collection, you can use the map function.
$query = $query->map(function ($object) {
// Add the new property
$object->promotion_image = URL::to('home/image/banner/' . $object->promotion_banner_id);
// Return the new object
return $object;
});
Also, you can get and set the properties using actual object properties and not array keys. This makes the code much more readable in my opinion.
For others who needs a solution you can use jsonserialize method to modify the collection.
Such as:
$data = $data->jsonserialize();
//do your changes here now.
The problem is the get is returning a collection of stdObject
Instead of adding the new field to the result of your query, modify the model of what you are returning.
So, assuming you have a PromotionBanner.php model file in your app directory, edit it and then add these 2 blocks of code:
protected $appends = array('promotionImage');
here you just added the custom field. Now you tell the model how to fill it:
public function getPromotionImageAttribute() {
return (url('home/image/banner/'.$this->promotion_banner_id));
}
Now, you get your banners through your model:
static function m_get_promotion_banner(){
return \App\PromotionBanner::where('promotion_active','1')->get();
}
Now you can access your promotionImage propierty in your result
P.D:
In the case you are NOT using a model... Well, just create the file app\PromotionImage.php:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class PromotionImage extends Model
{
protected $appends = array('imageAttribute');
protected $table = 'promotion_banner';
public function getPromotionImageAttribute() {
return (url('home/image/banner/'.$this->promotion_banner_id));
}
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'promotion_banner_id','promotion_link','about_promotion','promotion_active'
];
just improving, in case you need to pass data inside the query
$url = 'home/image/banner/';
$query = $query->map(function ($object) use ($url) {
// Add the new property
$object->promotion_image = URL::to( $url . $object->promotion_banner_id);
// Return the new object
return $object;
});
I've been struggling with this all evening, and I'm still not sure what my problem is.
I've used ->get() to actually execute the query, and I've tried by ->toArray() and ->jsonserialize() on the data and it didn't fix the problem.
In the end, the work-around I found was this:
$task = Tasks::where("user_id", $userId)->first()->toArray();
$task = json_decode(json_encode($task), true);
$task["foo"] = "bar";
Using json_encode and then json_decode on it again freed it up from whatever was keeping me from editing it.
That's a hacky work-around at best, but if anyone else just needs to push past this problem and get on with their work, this might solve the problem for you.
I'm trying to pull a column out of the database, simple enough right? I'm using codeigniter's active record.
My Model Function
public function getcolumn($field, $table, $kfield, $key)
{
$this->db->select($field);
$this->db->from($table);
$this->db->where($kfield, $key);
$query = $this->db->get();
$results = $query->result();
return $results;
}
My Controller has:
public function users()
{
$body['handle'] = $this->admin->getcolumn('handle', 'users', 'userid', $userid)
$this->load->view('template/header');
$this->load->view('admin/users', $body);
$this->load->view('template/footer');
}
now when I print_r that variable in my view I get "Array ( [0] => stdClass Object ( [handle] => Zanigade ) ) "
Since I'm trying to use this function as a global "grab and go" function without writing a ton of functions, why won't it just return the name? What am I doing wrong? I've been playing with the output for 3 hours and I know this is a stupid easy fix and I'm just missing the mark.
Any help will be appreciated.
Put it all together using the "chaining" capability like so
$results = this->db->get()->row()->$field;
We get() one row() which (should) contain a field named $field.
It seems you are returning the result instead of single row, try this
public function getcolumn($field, $table, $kfield, $key)
{
$this->db->select($field);
$this->db->from($table);
$this->db->where($kfield, $key);
$query = $this->db->get();
return $query->row()->$field;
}

i'm still really new to CodeIgniter. and i'm trying to find out how to delete row from my table. because when i use this function, i can;t delete my row.
does anyone know about the solution for this? and how can i get status if the delete is success or not?
public function deleteEpass($serial)
{
$this->db->trans_start();
$this -> db -> where('serial', $serial);
$this -> db -> delete('epass');
$this->db->trans_complete();
return $this->db->trans_status();
}
affected_rows( ) should return the number of rows affected. so you can use this.
$this -> db -> where('serial', $serial);
$this -> db -> delete('epass');
return $this->db->affected_rows();
$this->db->trans_begin();
$this->db->where('serial', $serial);
$this->db->delete('epass');
if (($this->db->trans_status() === FALSE)) {
$this->db->trans_rollback();
return FALSE;
} else {
$this->db->trans_commit();
return $this->db->affected_rows();
}
I have a problem, right now Im using this foreach loop on CakePhp on which I want to add all the values which are still not on the table for the respecting user. To give a little more context, the user has a menu. And the admin can select which one to add for the user to use. On the next code I receive a array with the menus which will be added as so:
//This is what comes on the ['UserMenuAccessibility'] array:
Array ( [menu_accessibility_id2] => 2 [menu_accessibility_id3] => 3 [menu_accessibility_id4] => 4 [menu_accessibility_id5] => 5 [menu_accessibility_id8] => 8 )
I get the ids of the menus which want to be added to the table for the user to use. And I use the next code to add the menus to the table if they are not there still:
//I check if the array has something cause it can come with no ids.
if (!(isset($this->request->data['UserMenuAccessibility']))) {
$this->request->data['UserMenuAccessibility'] = array();
}
$UserMenuAccessibility = $this->request->data['UserMenuAccessibility'];
foreach ($UserMenuAccessibility as $key => $value) {
$conditions = array(
'UserMenuAccessibility.menu_accessibility_id' => $value,
'UserMenuAccessibility.users_id' => $id
);
if ($this->User->UserMenuAccessibility->hasAny($conditions)) {
} else {
$valuemenu['UserMenuAccessibility']['users_id'] = $id;
$valuemenu['UserMenuAccessibility']['menu_accessibility_id'] = $value;
if ($this->User->UserMenuAccessibility->save($valuemenu)) {
} else {
$this->Session->setFlash(__('The user could not be saved. Please, try again.'));
}
}
}
For some reason the array is only saving the last new id which is not on the table and not the rest. For example if I have menu 1 and 2 and add 3 and 4 only 4 gets added to the table. For some reason I cant add all the missing menu ids to the table. Any ideas why this is happening?
Thanks for the help on advance.
It looks like your code will save each item, but each call to save() is overwriting the last entry added as $this->User->UserMenuAccessibility->id is set after the first save and will be used for subsequent saves. Try calling $this->User->UserMenuAccessibility->create() before each save to ensure that the model data is reset and ready to accept new data:-
$valuemenu['UserMenuAccessibility']['users_id'] = $id;
$valuemenu['UserMenuAccessibility']['menu_accessibility_id'] = $value;
$this->User->UserMenuAccessibility->create();
if ($this->User->UserMenuAccessibility->save($valuemenu)) {
}
In cakephp 2.0 $this->Model->create() create work fine. But if you are using cakephp version 3 or greater then 3. Then follow the below code
$saveData['itemId'] = 1;
$saveData['qty'] = 2;
$saveData['type'] = '0';
$saveData['status'] = 'active';
$saveData = $this->Model->newEntity($saveData);
$this->Model->save($materialmismatch);
In normal case we use patchEntity
$this->Model->patchEntity($saveData, $this->request->data);
It will only save last values of array so you have to use newEntity() with data
In cakephp3, patchEntity() is normally used. However, when using it for inserting-new/updating entries in a foreach loop, I too saw that it only saves the last element of the array.
What worked for me was using patchEntities(), which as explained in the patchEntity() doc, is used for patching multiple entities at once.
So simplifying and going by the original code sample to handle multiple entities, it could be:
$userMenuAccessibilityObject = TableRegistry::get('UserMenuAccessibility');
foreach ($UserMenuAccessibility as $key => $value) {
$userMenuAccessibility = $userMenuAccessibilityObject->get($value);//get original individual entity if exists
$userMenuAccessibilities[] = $userMenuAccessibility;
$dataToPatch = [
'menu_accessibility_id' => $value,
'users_id' => $id
]//store corresponding entity data in array for patching after foreach
$userMenuAccessibilitiesData[] = $dataToPatch;
}
$userMenuAccessibilities = $userMenuAccessibilityObject->patchEntities($userMenuAccessibilities, $userMenuAccessibilities);
if ($userMenuAccessibilityObject->saveMany($requisitions)) {
} else {
$this->Session->setFlash(__('The users could not be saved. Please, try again.'));
}
Note: I haven't made it handle if entity doesn't exist, create a new one and resume. That can be done with a simple if condition.
In hook_user_update I'm retrieving a facebook profile pic and saving a record in the file_managed table. That much is going well. But I also want to save a record for a file field attached to the user entity. Normally what I do in these hooks is assign the values to $edit['field_something'], and I think that's the correct way to do this. That has always worked for other field types, but it is not working for the file field. You can see toward the end of the function where I dump the vars to confirm that I have something suitable to assign to $edit['field_something'] -- at least, I think it's suitable. I get no errors, but no record is created in the field_data_field_image table. What am I missing? Thank you!
/**
* Implementation of hook_user_update().

*/
function hifb_user_update(&$edit, $account, $category) {
if (empty($account->field_image['und'])) {
$fbid = $edit['field_facebook_id']['und'][0]['value'];
if (!empty($fbid)) {
$url = 'http://graph.facebook.com/' . $fbid . '/picture?type=large';
if ($file_contents = file_get_contents($url)) {
$size = getimagesize($url);
$ext = image_type_to_extension($size[2]);
$filename = 'fb_' . $fbid . '_u_' . $account->uid . $ext;
$uri = file_default_scheme() . '://' . $filename;
// Saves the file to the default files directory and creates the record in files_managed table.
$file = file_save_data($file_contents, $uri, FILE_EXISTS_REPLACE);
//var_dump($file); die;
/* Here's an example from the var_dump: object(stdClass)#120 (8) { ["fid"]=> string(3) "576" ["uri"]=> string(30) "public://fb_767816596_u_1.jpeg" ["filename"]=> string(21) "fb_767816596_u_1.jpeg" ["filemime"]=> string(10) "image/jpeg" ["uid"]=> string(1) "1" ["status"]=> int(1) ["timestamp"]=> int(1339686244) ["filesize"]=> int(2919) } */
// Creates record in field_data_field_image table??
$edit['field_image']['und'][0] = (array)$file;
}
}
}
}
I believe the reason it doesn't work is because in hook_user_update, the update has already occurred. So setting a value for $edit has no effect. The same code that I posted in the question works fine in hook_user_presave.
