search query not working in laravel - php

Question

I need to return the results of what the user write in the search bar, but when i press search to test it nothing happens.
this is how i created the search bar
<form class="form-inline" role="search" action="{{ route('search-source') }}" method="POST">
{{ csrf_field() }}
<div class="form-group">
<input type="text" class="form-control" name="searchbar" placeholder="Find a source!">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
in my controller i have the following code to find what the user has entered in the search bar. It searches the datebase for a title thats like whats written in the search bar. If nothing is found it return's an error (this is working).
if a row higher than 0 return it need to bring that result back to the page
public function searchSource(Request $request){
$this->validate($request,[
'searchbar' => 'required',
]);
$find = $request['searchbar'];
$query = Source::where('title','LIKE', '%'.$find.'%')->where('user_id', Auth::user()->id)->get();
if(count($query) > 0) {
return redirect()->route('sources-index')->with(['query' => $query]);
}else{
return redirect()->route('sources-index')->with('customerror', 'nothing found, try a different searchterm.');
}
}
back on the page it need to get the result if there is asked for a searchterm, else it need to give everything of the database
#if(!empty($query))
#foreach($query as $querys)
<tr>
<td class="source-cell">
{{$querys->title}}
</td>
<td>
{{$querys->summary}}
</td>
<td>
{{$querys->course->name}}
</td>
</tr>
#endforeach
#else
#foreach ($sources as $source)
<tr>
<td class="source-cell">
{{$source->title}}
</td>
<td>
{{$source->summary}}
</td>
<td>
{{$source->course->name}}
</td>
</tr>
#endforeach
#endif
I tried dd() on a couple of places and everything worked fine, except on the page, i tried dd($query) after the if statement nothing happend.
I tried it after the foreach nothing happend.
But when i tried it before the if statement i got an error
Undefined variable: query (View:
...\resources\views\sources\index.blade.php)
What am i doing wrong.

Answer 1

In your above code $query is misspelled
Change
#if(!empty($uery))
to
#if(!empty($query))
Modify your controller like below :
public function searchSource(Request $request){
$this->validate($request,[
'searchbar' => 'required',
]);
$find = $request['searchbar'];
$query = Source::where('title','LIKE', '%'.$find.'%')->where('user_id', Auth::user()->id)->get();
return redirect()->route('sources-index')->with(['query' => $query]);
}
Modify your view like below :
#if(!empty($uery))
#foreach($query as $querys)
<tr>
<td class="source-cell">
{{$querys->title}}
</td>
<td>
{{$querys->summary}}
</td>
<td>
{{$querys->course->name}}
</td>
</tr>
#endforeach
#else
nothing found, try a different searchterm.
#endif
#if(!empty($sources))
#foreach ($sources as $source)
<tr>
<td class="source-cell">
{{$source->title}}
</td>
<td>
{{$source->summary}}
</td>
<td>
{{$source->course->name}}
</td>
</tr>
#endforeach
#else
nothing found, try a different searchterm.
#endif
Because in your else part redirection does not have $query variable.

Answer 2

redirect()->with() uses session to store the data, so you'll need to change the code to:
#if (session()->has('query'))
#foreach(session('query') as $querys)
Or, you need to change redirect() part to this:
return view('query.index', compact('query'));

# Peter Arents Could you please try as below
$query = Source::where('title', 'LIKE', "%$find%")->where('user_id', '=', Auth::user()->id);
