laravel, I click the search button so there is an error message "Whoops, looks like Something went wrong."
public function kategori(Request $request)
{
$keyword = $request['keyword'];
$kota = $request['city'];
$City= City::where('nameCity','<>',$kota)->get();
$Kate=Category::where('categoryType',$keyword)->get();
// $branch = Branch::where('branchName','LIKE',"%{$keyword}%")->paginate(30);
$branch = DB::table('mi_branch')->join('mi_resto_category', function ($join) use ($kota,$keyword)
{
$join->where('categoryType', 'LIKE', "%{$keyword}%");
$join->on('mi_branch.branchCategory', '=', 'mi_resto_category.categoryId');})
->where('branchVenue','=',"{$kota}")->orWhere('branchAddress','LIKE',"%{$keyword}%")
->where('branchVenue','=',"{$kota}")->orWhere('branchName','LIKE',"%{$keyword}%")
->where('branchVenue','=',"{$kota}")->orWhere('branchPointRules','LIKE',"%{$keyword}%")
->where('branchVenue',"{$kota}")->get();
return view('v_bykategori',compact(['brand'],['branch'],['kota'],['City'],['Kate'],['keyword']));

I have a problem when trying to access any route without parameter:
When I wrte any route without {uname} parameter like this or any other one:
http://127.0.0.1:8000/login/
show me this error :
and it is in the home in another controller?
These is my routes:
Route::get('/{uname?}', [HomeController::class, 'home'])->name('home');
Route::get('/info/{uname?}', [HomeController::class, 'info'])->name('info.me');
Route::get('/skills/{uname?}', [HomeController::class, 'skills'])->name('skills');
Route::get('/education/{uname?}', [HomeController::class, 'education'])->name('education');
Route::get('/achievements/{uname?}', [HomeController::class, 'achievements'])->name('achievements');
Route::get('/services/{uname?}', [HomeController::class, 'services'])->name('services');
Route::get('/contact/{uname?}', [HomeController::class, 'contact'])->name('contact');
Route::post('/send-email', [HomeController::class, 'sendEmail'])->name('send-email');
Route::get('/dashboard/index', [DashboardController::class, 'index'])->name('dashboard.index');
Route::resource('/dashboard/about', AboutController::class);
Route::resource('/dashboard/skills', SkillsController::class);
Route::resource('/dashboard/education', EducationController::class);
and here is my HomeController:
class HomeController extends Controller
{
function home($uname) {
$user = User::where('name', '=', $uname)->first();
$about = $user->about;
return view('home', compact('user', 'about'));
}
function info($uname) {
$user = User::where('name', '=', $uname)->first();
$about = $user->about;
return view('info', compact(['user', 'about']));
}
function skills($uname) {
$user = User::where('name', '=', $uname)->first();
$about = $user->about;
$skills = $user->skills;
return view('skills', compact(['skills', 'user', 'about']));
}
I have already tried those and nothing changed:
PHP artisan route: cache
PHP artisan cache:clear
Your home route is a catch-all route as you have an optional parameter right after your first dash (/). This will always catch first and stop any other routes from running because it will always match your current url. To solve this you need to put this kind of route as your last route.
As for your error it's because your not finding any user. If ->first() doesn't find a matching row it will return null, and if it's null you will get an error if you're treating it as an object. You either need to check if $user is null and set $about based on that or use firstOrFail and then create a response for that error.
Your error on line 13 of HomeController...
can't find user with your condition and return null and you in line 14 want get about from null....
you have to choose :
1 :
function home($uname) {
$user = User::where('name', '=', $uname)->first();
$about = $user->about ?? null ;
return view('home', compact('user', 'about'));
}
2:
function home($uname) {
$user=$about=null;
if(isset($uname)){
$user = User::where('name', '=', $uname)->first();
$about = $user->about ?? null ;
}
return view('home', compact('user', 'about'));
}
also you can change first() to firstOrFaill() in first method to get 404 page
$uname is an optional parameter. When it's not available no user could be found. You should check if $user is not null and return an error page or something like that, when $user is null.
if ($user !== null) {
$about = $user->about;
return view('home', compact('user', 'about'));
} else {
return view('error');
}
I need to Store when have data in [Booking] but din't store anything to [scan]
public function store(Request $request, $id){
$event = event::findOrFail($id);
$booking = booking::where('student_id',Auth::user()->student_id)
->where('name',Auth::user()->name)
->where('event_id',$event->id);
if($booking!=NULL){
$requestData = $request->all();
scan::create($requestData);
return redirect('event/' . $event->id .'/scan');
return view('event.scan', compact('event','scan','booking'));
}else{
return redirect('event/' . $event->id .'/scan');
}
}
but when using $booking==null
it store anything can't check in booking
Your query is incomplete. It lacks of any final query method like get(), first() or exists()
Also you have two return statements inside the if block. Only the first will be executed, the second one will be ignored.
The correct code should be like this:
public function store(Request $request, $id){
$event = event::findOrFail($id);
$booking = booking::where('student_id',Auth::user()->student_id)
->where('name',Auth::user()->name)
->where('event_id',$event->id)
->get(); // look this line
if($booking!=NULL){
$requestData = $request->all();
scan::create($requestData);
return redirect('event/' . $event->id .'/scan'); // I think this should not be here, right?
return view('event.scan', compact('event','scan','booking')); // this is being ignored.
}else{
return redirect('event/' . $event->id .'/scan');
}
}
you can update your method like so. its much clearer and readable (i think anyway).
public function store(Request $request, $id)
{
//use first to get a booking or use get() for collections of booking
$booking = Booking::where('student_id', auth()->user()->student_id)
->where('event_id', $id)
-first();
if (is_null($booking)) {
return redirect('event/' . $id . '/scan');
}
return view('event.scan', [
'event' => Event::findOrFail($id),
'scan' => Scan::create($request->all()),
'booking' => $booking
]);
}
Hope this helps
Cheers
I have an Laravel 5.4 Framework.I am going to send Json Request (in Controller) using Post Method.I would like to know how to how to convert Json Data to XML Data in Laravel
I have tried below code but its not working
public function store(Request $Request)
{
echo json_decode($Request);
}
You can do something like this its just an example
$age = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");
$root=null;
$xml = new SimpleXMLElement($root ? '<' . $root . '/>' : '<root/>');
array_walk_recursive($age, function($value, $key)use($xml){
$xml->addChild($key, $value);
});
echo $xml->asXML();
In your case : json_decode outputs array
public function store(Request $Request)
{
$data=json_decode($Request);
$root=null;
$xml = new SimpleXMLElement($root ? '<' . $root . '/>' : '<root/>');
array_walk_recursive($data, function($value, $key)use($xml){
$xml->addChild($key, $value);
});
echo $xml->asXML();
}
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']);
}
}
Assalamualaikum guys, i have some problems with my code. i tried to make search by using request parameters on laravel. and here is my code views.
$maintenance->with([
'user_post' => function($query, Request $request){
if($request->has('searchBy') && $request->has('searchQuery'))
{
$parse_query = explode('.',$request->query('searchBy'));
$is_user = $parse_query[0] == 'user_post'? true : false;
if($is_user)
{
$query->where($parse_query[1],'LIKE','%'.$request->query('searchQuery').'%');
}
}
},
'dt_project'
]);
when i tried to execute on browser, it return
1/1) ErrorException
Undefined variable: request
what should i do? thanks to the moon and back. hehehe
try this, change your line 2 to:
'user_post' => function($query) use($request){
explanation:
Request $request can only be used in controller functions like:
public function store(Request $request)
{
//code here
}
in order to pass the $request parameter inside another function, use use (this is also known as variable inheriting):
public function store(Request $request)
{
$user= User::with(['roles' => function($query) use($request){
^^^
$query->where('roles.id', $request['role_id'])->first();
}])->get();
}
