Call to a member function on a non-object [duplicate]
(8 answers)
Closed 1 year ago.
I'm trying to load into Select2 the selected value extracted from the DB. Id values are saved in a JSON field that contains the id values or the field '*' that I manage as 'All'.
I want to search first_name and last_name in the users' table.
AJAX
<script>
$(document).ready(function() {
$('#plaintiffId').select2({
ajax: {
url: '{{ route('admin::reports.plaintiffId') }}',
dataType: 'json',
delay: 250,
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
first_name: item.user.first_name,
last_name: item.user.last_name,
}
})
};
},
cache: true
}
});
</script>

Route::get('reports/plaintiffId', 'Admin\ReportController#plaintiffId')->name('reports.plaintiffId');

I get this error in the network
When I double-clicked on 500 in the network tab. It open a new tab, I see this error Call to a member function when() on string
$search is a string from request. You can use when only on Query Builder / Eloquent.

I want to filter the data in my table. I want if I select the first box it will show the data accordingly and if I select the second box it will show the data accordingly but the problem is that if I select the first box here the data does not show then the second box has to be selected.
Here is my controller code
public function UpazilaWiseReportShow(Request $request){
$data = [];
$data['report_data'] = Report::distric()->status(1)
->where('upazila_id',$request->upazila_id)->where('fiscal_year', $request->fiscal_year)
->get();
return view('adc.reports.upazilla-wise-data', $data);
}
here is my view code
<script>
$(document).ready(function() {
$('#upazila_id').on('change', function() {
getFilterData();
});
$('#fiscal_year').on('change', function (e) {
getFilterData();
});
});
function getFilterData() {
$.ajax({
type: "GET",
data: {
upazila_id: $("[name=upazila_id]").val(),
fiscal_year: $("[name=fiscal_year]").val()
},
url: "{{url('adc/upazila-wise-report')}}",
success:function(data) {
$("#report_data_table").html(data);
}
});
}
</script>
You should check if your $request has your needed fields. So you have to check if your request has these fields. You can use when method for it.
With the code below, you can either select fiscal year or upazila_id or both.
$data['report_data'] = Report::distric()
->status(1)
->when(
isset($request->upazila_id),
function ($query) use ($request) {
$query->where('upazila_id', $request->upazila_id);
}
)
->when(
isset($request->fiscal_year),
function ($query) use ($request) {
$query->where('fiscal_year', $request->fiscal_year);
}
)
->get();

You have $term parameter in your controller but you dont send any parameter to your controller, you should send term parameter by ajax to your controller
I am trying to get parent and child data and show it in Select2.
Model
// JobTypes model
public function jobs()
{
// one type of job has many jobs
return $this->hasMany('App\Jobs', 'id'); // id refer to jobs.id
}
// Jobs model
public function job_types()
{
// one job only belongs to one type of job
return $this->belongsTo('App\jobTypes');
}
Controller
$keyword = $this->request->get('q');
$categories = \App\JobTypes::with(['jobs' => function ($query) use ($keyword) {
$query
->whereHas('job_types')
->orWhereDoesntHave('job_types')
->where('name', 'LIKE', "%$keyword%");
}])->get();
return $categories;
View
$('#goals').select2({
maximumSelectionLength: 2,
ajax: {
url: '{{ url('showjobs') }}',
processResults: function(data) {
return {
results: data.map(function(item) {
return {
id: item.id,
text: item.name,
//childern
children: data.map(function(child){
return {
id: child.id,
text: child.name
}
})
// end childern
}
})
}
}
} });
But the result is not expected.
So, I want all of child data above coming from 'jobs' table. I've tried many times to solve this problem but still stuck here.
I did a multiselect input dropdown using select2. However, I dont really sure how to fetch the data that I call from database in the dropdown so that I can view it in datatable. Here are my codes:
Script for input dropdown select2:
$('.ethnicity').select2({
placeholder: 'Select..',
ajax: {
url: '/select2-autocomplete-ajax_ethnicity',
dataType: 'json',
delay: 250,
processResults: function ($ethnicity) {
return {
results: $.map($ethnicity, function (item) {
return {
text: item.Bangsa_updated,
id: item.id,
}
})
};
Controller for input dropdown so it will select the input typed:
public function ethnicity(Request $request)
{
$ethnicity = [];
if($request->has('q')){
$search = $request->q;
$ethnicity = DB::table("user")
->select("id","ethnic")
->where('ethnic','LIKE',"%$search%")
->get();
}
return response()->json($ethnicity);
}
The above code only to select the data from database without fetch data to datatable.
The controller below to catch data into datatable (I used this for simple dropdown, however dont know how to change so it is useful for above input dropdown.
public function fnFilter(Request $request)
{
if(request()->ajax())
{
if(!empty($request->dataGender))
{
$data = DB::table('user')
->select('id', 'Fn', 'Ln')
->where('ethnic', $request->ethnicity)
->get();
}
else
{
$data = DB::table('user')
->select('id', 'Fn', 'Ln', 'Umur', 'Phone', 'Dob','St', 'Country','Zip','Ct','Jantina')
->get();
}
return datatables()->of($data)->make(true);
}
$dataName = DB::table('modified_dpprs')
->select('ethnic','Jantina')
->groupBy('ethnic')
->orderBy('ethnic', 'ASC')
->get();
return response()->json($dataName);
Blade is:
<select id="ethnicity" class=" ethnicity form-control select2-allow-clear" style="width:200px;" name="namaDUN" multiple >
<option value="">Select</option>
My idea is to put the result from controller function ethnicity into function fnFilters. But I dont know how can do it.
you can return response in select2 (controller function) required format
like
$final_array = [];
$ethnicity = DB::table("user")
->select("id","ethnic");
if ($request->search != '') {
$search = $request->search ;
$ethnicity=$ethnicity->where('ethnic','LIKE',"%$search%");
}
// loop the results to make response
foreach($ethnicity->get() as $key => $value):
$final_array[$key]['id'] = $value->id;
$final_array[$key]['text'] = $value->ethnic;
endforeach;
return ['results' => $final_array];
// function ends here
and select 2 tag in blade file like this
$('.ethnicity').select2({
placeholder: 'Select..',
ajax: {
url: '/select2-autocomplete-ajax_ethnicity',
minimumInputLength: 3,
data: function (params) {
var query = {
search: params.term,
page: params.page || 1
}
return query;
}
}
});
public function index(Request $request)
{
$search_book = $request->id;
$proc=DB::select(DB::raw("SELECT * FROM BOOKS WHERE BOOKID = '$Search_book'")
if ($search_book!="") {
return response()->json($proc);
return view('status.status',[
'proc' => $proc
]);
}
How to return 2 data
To determine if a request is an ajax request, you can use the ajax() method on a Request object injected into the controll action:
public function index(Request $request)
{
$results = DB::table('books')
->where('bookid', $request->id)
->get();
if ($request->ajax()) {
return response()->json($results);
}
return view('status.status', [
'proc' => $results
]);
}
I went ahead and fixed the SQL injection vulnerability in your query for you by swapping the query for a proper one. It could still be improved by using a Book model instead of a plain database query, but it is fine this way as well.
The query from your comment can be simplified by replacing the left join. Simply take the sub query as base and right join it with processspj:
DB::table('processtrans as pt')
->leftJoin('processmaster as pm', 'pm.pcm_id', '=', 'pt.pct_pcm_id')
->rightJoin('processspj as ps', 'ps.pc_id', '=', 'pt.pct_pc_id')
->where('pt.pct_pc_id', $request->id)
->select([
'ps.*',
'pm.pcm_bname',
'pt.created_at',
'pt.updated_at',
'pt.pct_id',
'pt.pct_leadtime',
'pt.pct_pcm_id',
'pt.pct_pc_id',
'pt.pct_planfinishdate',
'pt.pct_startdate',
'pt.pct_status',
])
->get();
$(document).ready(function(){
$("#dl_books").change(function()
{
var getValue=$(this).val();
$.ajax({
type: 'GET',
url: '{{route('status')}}',
data: {id:getValue},
success:function(data)
{
//Json for value textbox
$("#txtbookname").text(data[0].pcm_bname);
}
});
});
});
Just save the rendered view in a variable and do a json response:
public function index(Request $request) {
$results = DB::table('books')
->where('bookid', $request->id)
->get();
if ($results) {
$view = view('status.status', [
'proc' => $results
])->render();
return response()->json(['view'=> $view, 'proc' => '$results']);
}
}
