In my Laravel web application, getting error like "Call to a member function setPath() on a non-object" while using pagination.
My code is
In model,
public function scopegetApartments()
{
$list1 = DB::table('properties')->orderBy('id','DESC')->paginate(1);
$list = array();
foreach($list1 as $listeach){
$imgs = DB::table('property_images')->where('property_id',$listeach->id)->get();;
$images = array();
foreach($imgs as $img){
array_push($images, $img->image);
}
$lists = array(
'id'=>$listeach->id,
'name'=>$listeach->name,
'rent'=>$listeach->rent,
'shortdescription'=>$listeach->shortdescription,
'images'=>$images,
);
array_push($list, $lists);
}
if(count($list)>0){
return $list;
}else{
return '[]';
}
}
In view,
$apartmentlist->setPath('serviceapartments');
echo $apartmentlist->render();
How to resolve this problem?

$chatterreply->save();
$chatterreplies = Chatterreply::where('chatter_post_id',$request->chatter_post_id)->get();
$chatter_editor = config('chatter.editor');
if ($chatter_editor == 'simplemde') {
// Dynamically register markdown service provider
\App::register('GrahamCampbell\Markdown\MarkdownServiceProvider');
}
echo "<pre>"; print_r($chatterreplies); die;
return view('chatter::discussion', compact('chatterreplies','chatter_editor'))->with('chatter_alert','Add Comment Successfully');
}
And Here Is Where I am passing the variable
$chatter = session()->pull('chatter');
return view('chatter::discussion', compact('discussion', 'posts', 'chatter_editor'))->with('chatterreplies',$chatter);
I am trying to update method in Laravel but error is:
"Call to a member function tradereason() on boolean"
I also check same question of other people asked but there're a lot of different in my process. I have lot tables.
let me show you my create code and update method coding.
Create method code:
public function store(Request $request)
{
$tradeID= Auth::user()->trade()->create($input);
$input = $request->all();
$reasons = $request->input('reason');
//Loop for creating KEY as Value
$data = [];
foreach($reasons as $key => $value) {
$data[] = ['reason_id' => $value];
};
if( $data > 0 ) {
foreach ($data as $datum) {
$tradeID->tradereason()->save(new TradeReason($datum));
}
}
}
this is my tring code for update method:
public function update(Request $request, $id)
{
$tradeID= Auth::user()->trade()->whereId($id)->first()->update($input);
$input = $request->all();
$reasons = TradeReason::whereId($id)->first();
$reasons->update($input);
$reasons->tradereason()->sync($request->input('reason'));
$data = [];
foreach($reasons as $key => $value) {
$data[] = ['reason_id' => $value];
};
if( $data > 0 ) {
foreach ($data as $datum) {
$tradeID->tradereason()->whereId($id)->first()->update($datum);
}
}
}
update returns a boolean. So, don't overwrite $tradeID with the results of update.
$tradeID = Auth::user()->trade()->whereId($id)->first();
$tradeID->update($input);
Calling update on the Builder returns an 'int'. Calling update on the Model returns a 'bool'. They don't return Model instances.
// bool
$tradeID= Auth::user()->trade()->whereId($id)->first()->update($input);
The model instance would be what is returned from the first call:
$tradeID = Auth::user()->trade()->whereId($id)->first(); // assuming it finds a record
You can update that, you can use it in the foreach loop.
I am trying to get the data in my view in codeigniter but it gives me a Message: Undefined variable: topics_array
here is my model :
public function studentTopics($courseId, $periodId)
{
$this->dbi->select('topicitem.TopicItemID, topicItem.Content');
$this->dbi->from('topicitem, topics, periods');
$this->dbi->where('topics.PeriodItemID', $periodId)
->where('topics.TopicItemID = topicitem.TopicItemID')
->where('topics.PeriodItemID = periods.PeriodItemID')
->where('periods.CourseID', $courseId);
$res = $this->dbi->result_array();
return $res;
}
here is my controller
public function student_topic($courseId, $periodId)
{
$this->load->library('table');
$this->load->model('Student_model');
$data['topics_array'] = $this->Student_model->studentTopics($courseId, $periodId);
$this->load->view('Student/StudentView', $data);
}
and my view
<?php
$courseID = $this->uri->segment(4);
$periodID = 1;
foreach ($topics_array as $key =>$value) {
echo "<tr>
<td>".$value['Content']. "</td>
</tr>"; }?>
You seem to be missing a get().
$res = $this->dbi->get()->result_array();
return $res;
Hope this will help you :
change this line of code : $res = $this->dbi->result_array();
$this->dbi->select('topicitem.TopicItemID, topicItem.Content');
$this->dbi->from('topicitem, topics, periods');
$this->dbi->where('topics.PeriodItemID', $periodId)
->where('topics.TopicItemID = topicitem.TopicItemID')
->where('topics.PeriodItemID = periods.PeriodItemID')
->where('periods.CourseID', $courseId);
$query = $this->dbi->get(); // missing this line of code
$res = $query->result_array();

This my controller function
public function update_monthly() {
$data = $this->student_model->get_due_info();
foreach ($data as $value) {
$due = $this->student_model->get_due_by_id($value);
$grade = $this->student_model->get_grade_by_id($value);
$grade_due = $this->student_model->get_due_by_grade($grade);
$new_due = $due + $grade_due;
$this->db->set('md_due',$new_due, FALSE);
}
}
I am getting following error
A PHP Error was encountered
Severity: Notice
Message: Array to string conversion
Filename: database/DB_active_rec.php

A Database Error Occurred

Model Code
public function get_due_by_id($id) {
$this->db->select('md_due');
$this->db->from('monthly_due');
$this->db->where('md_student_id', $id);
$query = $this->db->get();
return $query->result_array();
}
public function get_due_by_grade($id) {
$this->db->select('dt_fee');
$this->db->from('due_table');
$this->db->where('dt_grade', $id);
$query = $this->db->get();
return $query->result_array();
}
public function get_grade_by_id($id) {
$this->db->select('grade');
$this->db->from('student_info');
$this->db->where('student_gen_id', $id);

public function get_due_info() {
$this->db->select('md_student_id');
$this->db->from('monthly_due');
$query = $this->db->get();
return $query->result_array();
}
Pass $value['md_student_id'] to the model instead of $value in controller.
$data = $this->student_model->get_due_info();
foreach ($data as $value) {
$due = $this->student_model->get_due_by_id($value['md_student_id'] );
$grade = $this->student_model->get_grade_by_id($value['md_student_id']);
$grade_due = $this->student_model->get_due_by_grade($grade[0]['grade']);
//Add remaining logic
}
you are passing whole the array to your model not just the value you want
$due = $this->student_model->get_due_by_id($value);
the right thing is to pass
$value['md_student_id']
this is the value you actually want to pass
replace your code with this
foreach ($data as $value) {
$due = $this->student_model->get_due_by_id($value['md_student_id'] );
$grade = $this->student_model->get_grade_by_id($value['md_student_id']);
$grade_due = $this->student_model->get_due_by_grade($grade[0]['grade']);
$new_due = $due + $grade_due;
$this->db->set('md_due',$new_due, FALSE);
}
Ok I want to pass two variables from a controller to a model but I get some kind of error. Am I passing variables on right way? My syntax is:
Controller:
public function add_tag(){
if(isset($_POST['id_slike']) && isset($_POST['id_taga'])){
$slika = $_POST['id_slike'];
$tag = $_POST['id_taga'];
$this->load->model("Member_model");
$res = $this->Member_model->add_tags($slike, $tag);
foreach ($res->result() as $r){
echo $r->name;
}
}
else{
echo "";
}
}
Model:
public function add_tags(){
$data = array(
'tags_id' => $tag ,
'photos_id' => $slika
);
$check = $this->db->query("SELECT tags_id,photos_id FROM bridge WHERE bridge.tags_id='{$tag}' AND bridge.photos_id={$slika} ");
if($check->num_rows()==0){
$this->db->insert('bridge',$data);
$res = $this->db->query("SELECT name FROM tags where `tags`.`id`='{$tag}' ");
return $res;
}
}
you are passing variables correctly, but do not get them correctly in the model, which should look like this:
public function add_tags($slike, $tag){
//your other code
}
The following code write on the controller file:-
$data = array();
$this->load->model('dbmodel');
$data['item'] = $this->dbmodel->getData('*','catagory',array('cat_id'=>21));
$this->load->view('listing_view', $data);
The following code write on the dbmodel file:-
public function getData($cols, $table, $where=array()){
$this->db->select($cols);
$this->db->from($table);
$this->db->where($where);
$query = $this->db->get();
$result = $query->result();
return $result;}
