i have 2 table, 1st tabel name trans_tmbh_qty for record history value inserted to tabel 2nd frm_fancpu
this my structure tabel 1st
and this tabel 2nd with name frm_monitor
this now my full function on controller trans_tmbh_qty
public function create_action()
{
$this->_rules();
if ($this->form_validation->run() == FALSE) {
$this->create();
} else {
$data = array(
'merk' => $this->input->post('merk',TRUE),
'av_mobo' => $this->input->post('av_mobo',TRUE),
'av_prc' => $this->input->post('av_prc',TRUE),
'av_ram' => $this->input->post('av_ram',TRUE),
'av_hdd' => $this->input->post('av_hdd',TRUE),
'av_psu' => $this->input->post('av_psu',TRUE),

'user_modify_av' => $this->input->post('user_modify_av',TRUE),
'date_modify_av' => $this->input->post('date_modify_av',TRUE),
);
$fancpu = $this->input->post('merk', TRUE);
$av_fancpu = $this->input->post('av_fancpu', TRUE);
$this->M_fancpu->av_fancpu($fancpu,$av_fancpu
);
$this->M_fancpu->av_fancpu($fancpu,$av_fancpu);
$this->M_trans_tmbhqty->insert($data);
$this->session->set_flashdata('message', 'Create Record Success');

I want to update stock on qty_available_fancpu. if previously filled 10, and I inserted 5 on form. I need result 15. I have code now only replace number 10 with 5. and this my controller
$fancpu = $this->input->post('merk', TRUE);
$av_fancpu = array(
'qty_available_fancpu' => $this->input->post('av_fancpu'),
);
$this->M_fancpu->av_fancpu($fancpu,$av_fancpu);
and it my model on M_fancpu
function av_fancpu($fancpu,$av_fancpu)
{
$this->db->where('tipe_fancpu', $fancpu);
$this->db->update('tbl_fancpu', $av_fancpu);
}
You can try this solution for your problem :-
Controller.php file
class fancpu {
$fancpu = $this->input->post('merk', TRUE);
$av_fancpu = $this->input->post('av_fancpu', TRUE);
$this->M_fancpu->av_fancpu($fancpu,$av_fancpu);
}
Model.php file
function av_fancpu($fancpu,$av_fancpu) {
$this->db->set('qty_available_fancpu', 'qty_available_fancpu + ' . (int) $av_fancpu, FALSE);
$this->db->where('tipe_fancpu', $fancpu);
$this->db->update('tbl_fancpu');
}
I hope it will help.

The problem is when I entered a new name no data is added. A similar thing happen when I entered an already existing name. Still, no data is added to the database. I am still new to CodeIgniter and not entirely sure my query builder inside the model is correct or not.
In the Model, I check if the name already exists insert data only into the phone_info table. IF name does not exist I insert data into user_info and phone_info.
Controller:
public function addData()
{
$name = $this->input->post('name');
$contact_num = $this->input->post('contact_num');
if($name == '') {
$result['message'] = "Please enter contact name";
} elseif($contact_num == '') {
$result['message'] = "Please enter contact number";
} else {
$result['message'] = "";
$data = array(
'name' => $name,
'contact_num' => $contact_num
);
$this->m->addData($data);
}
echo json_encode($result);
}
Model:
public function addData($data)
{
if(mysqli_num_rows($data['name']) > 0) {
$user = $this->db->get_where('user_info', array('name' => $data['name']))->result_array();
$user_id = $user['id'];
$phone_info = array(
'contact_num' => $data['contact_num'],
'user_id' => $user_id
);
$this->db->insert('phone_info',$phone_info);
} else {
$user_info = array(
'name' => $data['name']
);
$this->db->insert('user_info', $user_info);
$user = $this->db->get_where('user_info', array('name' => $data['name']))->result_array();
$user_id = $user['id'];
$phone_info = array(
'contact_num' => $data['contact_num'],
'user_id' => $user_id
);
$this->db->insert('phone_info', $phone_info);
}
}
DB-Table user_info:
DB-Table phone_info:
Extend and change your model to this:
public function findByTitle($name)
{
$this->db->where('name', $name);
return $this->result();
}
public function addData($data)
{
if(count($this->findByTitle($data['name'])) > 0) {
//.. your code
} else {
//.. your code
}
}
Explanation:
This:
if(mysqli_num_rows($data['name']) > 0)
..is not working to find database entries by name. To do this you can use codeigniters built in model functions and benefit from the MVC Pattern features, that CodeIgniter comes with.
I wrapped the actual findByName in a function so you can adapt this to other logic and use it elswehere later on. This function uses the query() method.
Read more about CodeIgniters Model Queries in the documentation.
Sidenote: mysqli_num_rows is used to iterate find results recieved by mysqli_query. This is very basic sql querying and you do not need that in a MVC-Framework like CodeIgniter. If you every appear to need write a manual sql-query, even then you should use CodeIgniters RawQuery methods.
I want to display multiple images in a gridviews single row. For example: I have table A, Table B and table C.
Table A has my_id.
In Table B my_id is the foreign key. Along with my_id it has c_id.
Table C has c_id which is in reference in Table B.
Table C also has a filepath to display images.
in Table A i have my_id as follows:
1, 2, 3, 4, 5, 6.
In Table B i have my_id as follows.
1 ,1 ,1 ,2 ,3, 3.
In Table B i also have c_id as follows.
1, 2, 3, 4, 5, 6.
In table C my c_id's are:
1, 2, 3, 4, 5, 6. and these id's have filepath associated with each of them. They are different images.
Now my gridview should display 3 different images for my_id because of the foreign key constraints. but it displays only 1 image.
My code is below:
In my model
public function getPictogramsID()
{
$pictogramsID = SdsrefGhsPictograms::find()->where(['sdsref_id' => $this->sdsref_id])->all();
foreach ($pictogramsID as $picID){
return $picID->pictogram_id;
}
}
public function getPictogramPath()
{
$pictogramsID = GhsPictogram::find()->where(['pictogram_id' => $this->getPictogramsID()])->all();
foreach ($pictogramsID as $picID){
$pic = $picID->pictogram_filepath;
}
return $pic;
}
public function getPictogramUrl()
{
//var_dump($this->getPictogramPath()); exit();
return \Yii::$app->request->BaseUrl.'/web'.$this->getPictogramPath() ;
}
my index file grid view image code
[
'label' => 'Hazards',
'format' => 'raw',
'value' => function ($data) {
return Html::img($data->getPictogramUrl(), ['alt'=>'myImage','width'=>'20','height'=>'30']);
},
],
I am also trying to add a bootstrap tool tip to this.. tool tip is displaying successfully but I think the looping is not not done in a correct way so it is repeating my images.
here is my updated gridview code.
[
'label' => 'Hazards',
'format' => 'raw',
'value' => function ($data) {
$images = '';
// append all images
foreach($data->getPictogramName() as $name)
foreach ($data->getPictogramUrl() as $url)
$images = $images.Html::img($url,['alt'=>'','width'=>'30','height'=>'30', 'data-toggle'=>'tooltip','data-placement'=>'left','title' => $name ,'style'=>'cursor:default;']);
return $images;
}
],
You have few logical errors in model and grid view. In all these areas you are dealing with one item instead of three.
In your model
public function getPictogramsID()
{
$ids = [];
$pictogramsID = SdsrefGhsPictograms::find()->where(['sdsref_id' => $this->sdsref_id])->all();
foreach ($pictogramsID as $picID){
$ids[] = $picID->pictogram_id;
}
return $ids;// returning all three ids
}
public function getPictogramPath()
{
$pic = [];
$pictogramsID = GhsPictogram::find()->where(['pictogram_id' => $this->getPictogramsID()])->all();
foreach ($pictogramsID as $picID){
$pic[] = $picID->pictogram_filepath;
}
return $pic;
}
public function getPictogramUrl()
{
$url = [];
foreach($this->getPictogramPath() as $path):
$url[] = \Yii::$app->request->BaseUrl.'/web'.$path;
endforeach;
return $url; // returning al urls
}
Now in you view loop over all urls and append images with each url
[
'label' => 'Hazards',
'format' => 'raw',
'value' => function ($data) {
$images = '';
// append all images
foreach($data->getPictogramUrl() as $url):
$images = $images.Html::img($url, ['alt'=>'myImage','width'=>'20','height'=>'30']);
endforach;
return $images;
},
],
I want to change the date of a doctrine entity but the change is not saved.
With ajax a call this function:
public function relancerTicketAction(Request $request, $id)
{
if (!$this->get('session')->get('compte'))
return $this->redirect($this->generateUrl('accueil'));
$isAjax = $request->isXMLHttpRequest();
if ($isAjax)
{
$ticket = $this->getDoctrine()->getManager()->getRepository('CommonBundle:Ticket')->find($id);
$ticket->setDateButoire($ticket->getDateButoire()->modify('+7 day'));
$this->getDoctrine()->getManager()->flush();
$response = array("code" => 100, "success" => true, 'date' => $ticket->getDateButoire()->format('d-m-Y'));
return new Response(json_encode($response));
}
$response = array("code" => 0, "success" => false);
return new Response(json_encode($response));
}
When I alert the result I get the right new value, but after reload there is no change saved.
This function called in the same conditions works:
public function traiterTicketAction(Request $request, $id)
{
if (!$this->get('session')->get('compte'))
return $this->redirect($this->generateUrl('accueil'));
$isAjax = $request->isXMLHttpRequest();
if ($isAjax)
{
$compte = $this->getDoctrine()->getManager()->getRepository('CommonBundle:Compte')->find($this->get('session')->get('compte')->getId());
$ticket = $this->getDoctrine()->getManager()->getRepository('CommonBundle:Ticket')->find($id);
$ticket->addDestinataire($compte);
$this->getDoctrine()->getManager()->flush();
$response = array("code" => 100, "success" => true);
return new Response(json_encode($response));
}
$response = array("code" => 0, "success" => false);
return new Response(json_encode($response));
}
see the docs
When calling EntityManager#flush() Doctrine computes the changesets of
all the currently managed entities and saves the differences to the
database. In case of object properties (#Column(type=”datetime”) or
#Column(type=”object”)) these comparisons are always made BY
REFERENCE. That means the following change will NOT be saved into the
database:
/** #Entity */
class Article
{
/** #Column(type="datetime") */
private $updated;
public function setUpdated()
{
// will NOT be saved in the database
$this->updated->modify("now");
}
}
So, in your case I suggest to clone dateButoire, like this
$ticket = $this->getDoctrine()->getManager()->getRepository('CommonBundle:Ticket')->find($id);
$newDateButoire = clone $ticket->getDateButoire();
$ticket->setDateButoire($newDateButoire->modify('+7 day'));
$this->getDoctrine()->getManager()->flush();
Im working with codeigniter and have a controller and 3 model functions to read, insert and update a column of table.
i want to get count of view from db and update it per each view!
but after the update an extra row added to table! with zero value for content_id.
please check once!
this is my controller:
public function daily_report($id="")
{
$counter=$this->home_model->counter($id);
if($counter)
{
$view=$this->home_model->counter($id)->row()->view;
$views=$view+1;
$this->home_model->update_counter($views,$id);
}
else{
$views=1;
$this->home_model->set_counter($views,$id);
}
}
This is the model functions:
public function counter($id)
{
$code=$id;
$lang=$this->session->userdata('lang');
$data = $this->db
->select('view')
->from('tbl_views')
->where("content_id",$code)
->where("language",$lang)
->get();
if ($data->num_rows() > 0) {
return $data;
}else{
return false;
}
}
public function set_counter($views,$id)
{
$data = array(
'content_id' => $id ,
'view' => $views,
'language'=>$this->session->userdata('lang')
);
$this->db->insert('tbl_views', $data);
}
public function update_counter($views,$id)
{
$data = array(
'view' => $views,
);
$this->db->where('content_id', $id);
$this->db->update('tbl_views', $data);
}
I'm using codeigniter version 2.0.3. I'm trying get the number of affected rows after an update query using
$this->db->affected_rows
It always returns 1 even if no row had been updated. I tried with
mysql_affected_rows()
and it returns -1 for a query failure and 0 if no record had been updated .
Edit included my code
I'm just using
$country_id = $this->input->post('country_id');
$time=$this->input->post('time');
$insert_array = array(
'country' => $this->input->post('name')
);
$this->db->update('country_master', $insert_array, array("country_id" => $country_id,"last_updated"=>$time));
$afftectedRows=$this->db->affected_rows();
Actually my code was like this
if (!$country_id) {
$this->db->insert('country_master', $insert_array);
$id = $this->db->insert_id();
} else {
$this->db->update('country_master', $insert_array, array("country_id" => $country_id, "last_updated" => $time));
}
$afftectedRows = $this->db->affected_rows();
And i modified it to
if (!$country_id) {
$this->db->insert('country_master', $insert_array);
$id = $this->db->insert_id();
} else {
$this->db->update('country_master', $insert_array, array("country_id" => $country_id, "last_updated" => $time));
$afftectedRows = $this->db->affected_rows();
}
And its working fine now.
And thank you very much for the replies..
