codeignite trying to get property of non-object not resolved - codeigniter

I am attempting to access the result set from a model query in the view. I have the following:
Controller:
$courseId = $this->session->userdata('courseId');
//echo "Course: ".$courseId;
if(isset($courseId) && $courseId != '')
{
$result = $this->Course_model->loadBasicDetailsEdit($courseId);
$data['basicCourseDetails'] = $result;
$this->load->view('course/basicDetails', $data);
}
Model:
function loadBasicDetailsEdit($courseId)
{
$this->db->select('*');
$this->db->where('course_id', $courseId);
$this->db->from('course');
$query = $this->db->get();
if ( $query->num_rows() > 0 )
{
return $query->result();
} else {
return FALSE;
}
}
and in the view I tried to print_r() and got this:
Array ( [0] => stdClass Object ( [course_id] => 8 [title] => Photography [summary] => [description] => [price] => [member_id] => 12 [category] => [audience] => [goals] => [date] => 2013-09-26 [production] => 0 ) )
I tried to access this using $basicCourseDetails->title or $basicCourseDetails['title']
but neither are working. Any hint as to why this is happening?
Regards,

try this:
foreach($basicCourseDetails as $basic){
echo($basic->title);
}
or something like this:
echo($basicCourseDetails[0]->title);

This is an array of objects
Array ( [0] => stdClass Object ( [course_id] => 8 [title] => Photography [summary] => [description] => [price] => [member_id] => 12 [category] => [audience] => [goals] => [date] => 2013-09-26 [production] => 0 ) )
Contains one stdObject in the array, so, first objects is 0, if there were more, then second item could have index 1 and so on. To retrieve data from the first (here is only one) stdobject you may use
echo $basicCourseDetails[0]->title; // title will be printed

You can send data to the view page by this line of code which is mentioned in above question.
$result = $this->Course_model->loadBasicDetailsEdit($courseId);
$data['basicCourseDetails'] = $result;
$this->load->view('course/basicDetails', $data);
But when you will access these data in view then you need to access all data one by one by using foreachloop in the view page.
For example if you have a view page like basic_details.php inside course folder then you need to write code like this to access these data.
foreach ($basicCourseDetails as $key => $value) {
$name = $value->name;
}
The above foreachloop can be written in view page where you want to access data.

I need To All Data In $qryy It Return Only Last Record

How I Return all data of $qryy it's return me only last record. How I need return all off data.
public function get_subcategory(){
$qry = $this->db->get("shopping_category");
foreach($qry->result() as $row){
$this->db->where("c_id",$row->id);
$qryy = $this->db->get("shopping_subcategory");
}
return $qryy;
}
You can try this
public function get_subcategory() {
$result = [];
$qry = $this->db->get("shopping_category");
foreach ($qry->result() as $row) {
$this->db->where("c_id", $row->id);
$qryy = $this->db->get("shopping_subcategory");
$result[] = $qryy;
}
return $result;
}
The reason you get the last record is, every time you loop data through foreach it keeps replacing $qryy = $this->db->get("shopping_subcategory");
to fix this you can simply change $qryy into an array $qryy[] like this.
To improve your query. you can simply try
$qryy = [];
$this->db->select("shopping_subcategory.*");
$this->db->from("shopping_category");
$this->db->join('shopping_subcategory', 'shopping_category.id = shopping_subcategory.c_id');
$sql= $this->db->get();
$qryy = $sql->result_array();
$data['category'] = $qryy;
$this->load->view('view_name', $data);
In view
$category will show your data
I think it solve your problem. would you mind if you give it a try?
since you want from table shopping_category is only id i try to fetch it so it's not a heavy duty on your server.
$result = [];
$qry = $this->db->select("id")->get('shopping_category');
foreach ($qry->result() as $row) {
$this->db->where("c_id", $row->id);
$qryy = $this->db->get("shopping_subcategory")->result();
$result[] = $qryy;
}
return $result;
Hope that helps :)
you should use another approach to resolve your problem: use joins to query the database only once:
$this->db->join("shopping_subcategory t2","t2.c_id=t1.id");
$qry = $this->db->get("shopping_category t1");
return $qry->result();
if you output above with print_r($qry->result()), you get similar to below:
Array
(
[0] => stdClass Object
(
[ID] => 1
[company_ID] => 1
[name] => aaa
)
[1] => stdClass Object
(
[ID] => 2
[company_ID] => 1
[name] => bbb
)
[2] => stdClass Object
(
[ID] => 4
[company_ID] => 2
[name] => ccc
)
)
to resolve your approach: you need to make $qryy an array, to store each subquery data, right now you are overwriting the variable $qryy with each loop and therefore only get the last result:
$qry = $this->db->get("shopping_category");
$qryy=array();
foreach($qry->result() as $i=>$row){
$this->db->where("c_id",$row->id);
$qryy[$i] = $this->db->get("shopping_subcategory")->result();
}
return $qryy;
if you output above with print_r($qryy), you get similar to below:
Array
(
[0] => Array
(
[0] => stdClass Object
(
[ID] => 1
[company_ID] => 1
[name] => aaa
)
[1] => stdClass Object
(
[ID] => 2
[company_ID] => 1
[name] => bbb
)
)
[1] => Array
(
[0] => stdClass Object
(
[ID] => 4
[company_ID] => 2
[name] => ccc
)
)
)
therefore, depending which approach you use, you'll need to take care of your data output differently.

whereBetween passing array

Hi I have query where I want to pass an array to whereBetween query.
for example I have an array which looks like this
Array
(
[product_id] => Array
(
[0] => 31337
[1] => 31366
)
[lands] => Array
(
[0] => 12
[1] => 23
)
)
Now I want search those product_id which are between [0] => 31337 and [1] => 31366 and same goes to land I want to find the lands where Between [0] => 12 and [1] => 23
now say I have a variable $filters which has the this above array in it and I pass it like this to the query like below.
public function scopeDynamicInBetweenFilter($query, $filters)
{
if(!empty($filters)){
return $query->whereBetween($filters);
}
return $query;
}
It gives me an error
Type error: Too few arguments to function Illuminate\Database\Query\Builder::whereBetween(), 1 passed and at least 2 expected
it does like this at
Builder->whereBetween('product_id' => array('31337', '31366'))->whereBetween('lands' => array('12', '23'))
what could be done to achieve this.
You could try to loop through the filters and apply it to the query
public function scopeDynamicInBetweenFilter($query, $filters)
{
if(! empty($filters)) {
if (is_array($filters)) {
foreach ($filters as $key => $value) {
$query->whereBetween($key, $value);
}
}
}
return $query;
}
Try this:
if(!empty($filters)){
return $query->whereBetween('product_id', $filters['product_id'])->whereBetween('lands', $filters['lands']);
}

sorting and filtering not working in custom admin module

I am trying to implement an admin module in magento which has a grid in the first page and grids in the tabs while editing the grid entities.
The main grid works fine, but the grids in the tabs are not working fine.
The problem I found while I debugged the code is that, I am loading the collection in the grid with field filtering, ie I am filtering the collection with filter that is the user id. I did this because I need only data of a single user from the table. This made the entire problem, the data in the grid is coming correctly, but the filtering,sorting and searching feature inside grid is not working and returning a 404 not found error page. I tried removing the field filter I added while getting the collection, then it works fine but all the data in the table is coming which is the opposite to my requirement.
Is there any possible solution to this. Here is the way I am trying to do:
protected function _prepareCollection() {
$collection = Mage::getModel('merchant/subscriptions')->getCollection()->addFieldToFilter('user_id', Mage::registry('merchant_data')->getId());
$this->setCollection($collection); //Set the collection
return parent::_prepareCollection();
}
Thanks in advance.
ok My problem is solved there is a mistake in my code. In the grid file the function below was wrong.
public function getGridUrl() {
return $this->getUrl('*/*/transactiongrid', array('user_id',Mage::registry('merchant_data')->getId(), '_current' => true));
}
The correct method was
public function getGridUrl() {
return $this->getUrl('*/*/transactiongrid', array('user_id'=> Mage::registry('merchant_data')->getId(), '_current' => true));
}
Filter action is dependent on your below method:
public function getGridUrl() {
return $this->getUrl('*/*/grid', array('user_id' => Mage::registry('merchant_data')->getId(),'_current'=>true));
}
now this is how you will prepare collection:
protected function _prepareCollection()
{
$regData = Mage::registry('merchant_data');
if(isset($regData))
$regData = $regData->getId();
else
$regData = $this->getRequest()->getParam('user_id');
$collection = Mage::getModel('merchant/subscriptions')->getCollection()->addFieldToFilter('user_id',$regData);
...
When I dumped $regData I got this:

Use Array Data in CodeIgniter Model as SQL?

In my controller, I am passing data to the model using the following code:
$data = array(
'gid' => $this->input->post('gid'),
'name' => $this->input->post('name'),
'pic' => $this->input->post('pic'),
'link' => $this->input->post('link')
);
var_dump($data);
$this->Login_model->insert_entry($data);
In my model, what I want to do is use the gid value as part of an SQL statement, like so:
$get_gid = $this->db->query('SELECT * FROM users WHERE gid = $gid');
Obviously this doesn't work, so I'm just wondering how I get the gid from $data and use it in my SQL statement?
Tested using
$get_gid = $this->db->where('gid', $data['gid'])->get('users');
print_r($get_gid);
However output is:
CI_DB_mysql_result Object ( [conn_id] => Resource id #30 [result_id]
=> Resource id #33 [result_array] => Array ( ) [result_object] => Array ( ) [custom_result_object] => Array ( ) [current_row] => 0
[num_rows] => 0 [row_data] => )
Did you try gid = $data['gid']
I assume that yours model method looks like this:
insert_entry($data)
{
here active record or query...
}
If yes try to display query to see if $data['gid'] is visible there
You can try it by
$this->db->get_compiled_select();
Or after query runs
$this->db->last_query();
Try this way:
$data = array(
'gid' => $this->input->post('gid'),
'name' => $this->input->post('name'),
'pic' => $this->input->post('pic'),
'link' => $this->input->post('link')
);
$gid = $data['gid'];
$this->db->where('gid',$gid);
$this->db->from('users');
$query = $this->db->get();
if($query)
{
//you can return query or you can do other operations here like insert the array data
//$this->db->insert('yourtable',$data);
return $query;
}
else
{
return FALSE;
}
You can try:
$get_gid = $this->db->query('SELECT * FROM users WHERE gid = '.$data['gid'].');
You just Forget after query $query->result().

pass multi-dimensional array from controller to view codeignighter

how do i pass a multi diminutional array to a view?
controller code
public function index(){
data['navs'] = array(
'name' => array('one', 'two', 'three'),
'link' => array('one', 'two', 'three'));
$this->load->view('adminView', $data);}
view code
<?php if ($navs) {
foreach ($navs as $nav) {
echo('<li>' . $nav->name . '</li>');
}
}?>
First of all you need to build the array, the right way. It should be something like:
$data['navs'] = array( array( 'name' => 'one',
'link' => 'linkone'),
array( 'name' => 'two',
'link' => 'linktwo')
);
$this->load->view('adminView', $data);
Then in your view:
foreach($navs as $n){
echo "<li><a href='{$n['link']}'>{$n['name']}</a></li>";
}
Once in the view, refer to your data as array elelements, not object properties (you are passing the array of arrays, not array of objects). Based on your controller, your view code should look like that:
foreach ($navs as $nav) {
echo('<li>' . $nav['name'] . '</li>');
}
However, that won't output the right result because your $nav['link'] and $nav['name'] are two arrays. You'd need to call any of their elements or change controller accordingly.
