I have 2 table :
product_group
product
which is every product have group_id as Foreign Key in the table.
I try to call every product by group_id.
this is my list_group view :
<i class="icon-line-ellipsis"></i>
I try to attach the group_id in URL.
this is my controller :
public function get_product_by_group($group_id)
{
if($this->uri->segment(3))
{
$this->load->database();
$group_id = $this->input->get('group_id', TRUE);
$data['product_data'] = $this->group_model->list_product_by_group($group_id);
$this->load->view('fend/list_product', $data);
}
else
{
redirect('list_group');
}
}
This is my model :
function list_product_by_group($group_id)
{
$this->db->select('*');
$this->db->where('group_id', $group_id);
$query = $this->db->get('product');
return $query->result();
}
and the last is list_product view :
<?php
foreach($product_data as $value)
{
?>
<div class="masonry-thumbs col-3" data-big="2" data-lightbox="gallery">
<img class="image_fade" src="<?= base_url('uploads/'. $value->product_picture);?>" alt="Gallery Thumb 1">
</div>
<?php
}
?>
I got no error, but the data did not appear in product_view.
Thanks for your help :))
If you remove the line $group_id = $this->input->get('group_id', TRUE); it will solve your problem.
Here is the explanation:
Your controller function name is public function get_product_by_group($group_id) so when you go to this link localhost/norwin/list_group/get_product_by_group/1 1 will be passed as $group_id into your get_product_by_group function.So your final function will be like this
public function get_product_by_group($group_id='')
//write this way so that you can call the url like
//localhost/norwin/list_group/get_product_by_group
{
if($group_id)//no need to check uri->segment
{
$this->load->database();
$data['product_data'] = $this->group_model->list_product_by_group($group_id);
$this->load->view('fend/list_product', $data);
}
else
{
redirect('list_group');
}
}

I have a controller it take multiple model function results and pass it to controller I did it like this
adpreview_ctrl.php
public function showBusinessReviews($vehicleid){
$data=array();
$data['details']=$this->ads_model->getBusinessReviews($vehicleid);
$data['noOfReviews']=$this->ads_model->countReviews($vehicleid);
$this->load->view('pages/templates/header');
$this->load->view('pages/viewReviews',$data);
$this->load->view('pages/templates/footer');
}
public function countBusinessReviews($vehicleid){
$data['details']=$this->ads_model->countReviews($vehicleid);
$this->load->view('pages/templates/header');
$this->load->view('pages/viewReviews',$data);
$this->load->view('pages/templates/footer');
}
}
viewReviews.php
<?php
foreach($noOfReviews as $reviewAmount){
echo $reviewAmount.'Reviews';
}
foreach($details as $review){
$Breview=$review->rating;
if($details==null)
{?>
<?php echo '<center><b><h3>No any reviews has been posted yet!</h3></b></center>';?>
<input type="submit" name="ok" class="btn btn-primary btn-lg" value="ok">
<?php }
else{
?>
Ads_model.php
public function getBusinessReviews($Vehicleid){
$status="Approved";
$this->db->select("*");
$query=$this->db->where('Vehicleid',$Vehicleid);
$query=$this->db->where('Status',$status);
$query=$this->db->get('businessreviews');
return $query->result();
}
public function countReviews($Vehicleid){
$status="Approved";
$this->db->select("*");
$query=$this->db->where('Vehicleid',$Vehicleid);
$query=$this->db->where('Status',$status);
$query=$this->db->get('businessreviews');
return $query->num_rows();
}
what I need to know is, it gives error saying it cannot identify $noOfReviews.
foreach($noOfReviews as $reviewAmount){
echo $reviewAmount.'Reviews';
}
I need to know how to retrieve multiple model function data in view,
and $noOfReviews only gives the no of reviews, a user has given. So their, without using a foreach loop how can i get the value of that, using a foreach loop is not necessary here.
Try this:
model:
public function countReviews($Vehicleid) {
$status = "Approved";
$this->db->select("*");
$query = $this->db->where('Vehicleid', $Vehicleid);
$query = $this->db->where('Status', $status);
// it will return with only the number of data
return $query->count_all_results('businessreviews');
}
viewReviews.php
<?php
// show number of reviews
echo $noOfReviews . 'Reviews';
// show details if exists
if(!empty($details)) {
foreach($details as $review) {
// echo what you want
}
} else {
echo 'No details.';
}
?>
Please help me. i can not use my dataTable properly. what I want to do is
select from table and use thewherefunction. but i cant do it properly.
here is my controller code
public function reporttable ()
{
$zz = array('empnumber' => $this->input->post('empnumber'));
//$this->db->order_by("surname", "asc");
$this->datatables->select('date_auto,particulars,earned_VL,aul_VL,balance_VL,aulx_VL,earned_SL,aul_SL,balance_SL,aulx_SL,date_leave,action_taken')
->from('tblreport')->where($zz);
echo $this->datatables->generate();
}
this is my supposed query:
select * from tblreport where empnumber = (the empnumber in my textbox.)
there, i get a value from a textbox to my view. but it didn't work. i know that is wrong. can you please help me with my problem? thank you.
<p align="center"> <?php echo $this->table->generate();?></p></div>
<?php foreach ($tblemployee as $row){?>
<input type="text" name="empnumber" readonly="readonly" value="<?php echo $row->empnumber;?>"/>
<input type="hidden" name="empnumber" value="<?php echo $row->empnumber;?>"/>
here is my view for guide. thank you.
as Simple you can use
In Controller
$data['tblemployee'] = $this->model_name->reporttable($id)//assign your data base value to variable
$this->load->view('your view name',$data )
in Model
public function reporttable($id)
{
$query = $this->db->query("select * from tblreport where empnumber = '$id'");
$result = $query->result_array();
return $result; // this will return your data as array
}
In view
<?php
foreach ($tblemployee as $row)
{
echo $row['id];
}?>
Try this :
To make it more simplier.
In model :
public function reporttable ($id){
$this->db->select('*');
$this->db->from('tblreport');
$this->db->where('empnumber', $id);
$query = $this->db->get();
return $query->return_array(); // use this if so want to return many query if not you can also use first_row('array')
}
In controller :
public function function_name (){
$data['variable_name'] = $this->model_name->reporttable($id); // change the model_name by your own model where your function reporttable is located and use the variable_name for your view,
$this->load->view('view_name' , $data); // load the view page you want to display.
}
In Controller
$data['tblemployee'] = $this->model_name->reporttable($id)//assign your data base value to variable
$this->load->view('your view name',$data )
in Model
public function reporttable($id)
{
$query = $this->db->query("select * from tblreport where empnumber = '$id'");
$result = $query->result_array();
return $result; // this will return your data as array
}
In view
<?php
foreach ($tblemployee as $row)
{
echo $row['id];
}?>
I am trying to get data from a database and display it using a model, controller, and view.
Here is my model
public function waitlist_view() {
$data = array();
$this->load->database();
$this->db->select('*');
$this->db->from('waitlist');
$query = $this->db->get();
return $query->row();
}
Here is my controller
public function waitlist() {
$data['title']="parents_viewlist";
//redirect if not logged in
if(($this->session->userdata('logged_in')!= 1) && ($this->session->userdata('type')!='parent')) {
redirect('login/index');
}
$this->load->model('parents_model');
$data['row'] = $this->parents_model->waitlist_view();
$this->load->view('templates/cpsheader', $data);
$this->load->view('templates/cpsmenu');
$this->load->view('parents/parents_viewlist', $data);
$this->load->view('templates/cpsfooter');
}
Here is my view
<div>
<?php echo $row->waitlist_id; ?>
<?php echo $row->ay_code; ?>
<?php echo $row->school_id; ?>
<?php echo $row->waitlist_status; ?>
</div>
It doesnt display anything on the page when I pull it up. Any help would be appreciated!
in your model use result() to get data :
public function waitlist_view() {
$this->load->database();
$query = $this->db->get('waitlist')->result();
return $query;
}
in your controller :
$this->load->model('parents_model');
$data['row'] = $this->parents_model->waitlist_view();
$this->load->view('templates/cpsheader', $data);
$this->load->view('templates/cpsmenu');
$this->load->view('parents/parents_viewlist', $data);
$this->load->view('templates/cpsfooter');
Now use loop on $row in your view to print data.
In your controller print the data returned from db as:
echo "<pre>";print_r($data);echo "</pre>";exit;
add this line just after $data['row'] = $this->parents_model->waitlist_view();
Let us know what result are you getting.
It was hard to come up with a title. I am using CodeIgniter with models/views/controller. I have the following tables in my MySQL database that are relevant:
In my model I have the following function:
function get_shoptable() {
$this->db->from('productshop')->where('productId', $this->productId);
$query = $this->db->get();
return $query->result();
}
In my controller I use the above function like
$data['bookshop'] = $this->Product_model->get_shoptable();
In my view I am foreaching $bookshop. My problem is, what is the best wayto show shopName, instead of showing shopId. Taking in regards that $bookshop should be as it is (except of shopid), because I am creating a HTML table with product data.
Try some like this:
function get_shoptable() {
$this->db->from('productshop')
->join('shop', 'productshop.shopId = shop.shopId')
->where('productshop.productId', $this->productId);
$query = $this->db->get();
return $query->result();
}
Model:
function get_products() {
$this->db->select('productshop.productUrl, productshop.price, productshop.deliveryTime, productshop.shippingCast, productshop.inventory, productshop.productId, productshop.shopId, shop.shopName');
$this->db->from('productshop');
$this->db->join('shop', 'productshop.shopId = shop.shopId');
$this->db->where('productshop.productId', $this->productId);
return $this->db->get()->result_array();
}
Controller:
function products() {
$data['products'] = $this->model_name->get_product();
$this->load->view('products', $data);
}
VIEW:
<?php foreach($products as $p): ?>
<h1><?php echo $p['productUrl']; ?></h1>
<h1><?php echo $p['shopName']; ?></h1>
<?php endforeach(); ?>
get an overlook to active class of codeigniter for details of functions
function get_shoptable()
{
$this->db->from('productshop')
$this->db->join('shop', 'productshop.shopId = shop.shopId')
$this->db->where('productshop.productId', $this->productId);
$query = $this->db->get();
return $query->result();
}
im creating a function to delete a contact record, then once deleted go to the view company page.
so here is my controller
public function delete($id) {
if (isset($_GET["delete"]))
{
$this->Contacts_model->delete($id);
$url = "/company/view/" . $cid;
redirect($url);
}
}
and here is my model
public function delete($id)
{
$this->db->where('id', $id);
$this->db->delete('contacts');
}
on my view:
<a href="/contacts/delete/<?php echo $data['id']; ?>
which this works and will delete the contact, but obviously wont redirect to the company/view page becuase the CID isnt being passed.
i thought about adding this to the delete link
<a href="/contacts/delete/<?php echo $data['id']; ?>?delete&cid=<?php echo $data['cid']; ?>"
so that cid is being passed through the url. would this work some way?
You can pass the cid in the url like
delete
In your controller function get the second parameter as $cid or from uri segment
public function delete($id,$cid) {
if (isset($_GET["delete"]))
{
$this->Contacts_model->delete($id);
$url = "/company/view/" . $cid;
redirect($url);
}
}
Here is uri segment documentation
