i tried to view data from database as per shown but get this error
$testjson = new TestJson ;
$testjson = $testjson->Where('id',2)->get();
return view('viewjson')->with('alldata',Json_decode($testjson));
user below code to view data
#foreach($alldata as $key => $value)
{{ $key }} - {{ $value }} <br>
#endforeach
can't get scope data
0 - {"id":2,"token":"2020-04-06 12:02:15","data":"{\"scope\":[\"volvo\",\"saab\",\"opel\",\"audi\"]}","created_at":"2020-04-06 12:02:15","updated_at":"2020-04-06 12:02:15"}
database
$testjson = new TestJson ;
$testjson = $testjson->Where('id',2)->get();
return response()->json(['data' => $testjson]);
If you are displaying in laravel view then no need to convert in json
$alldata = TestJson::find(2);
return view('viewjson', compact('alldata'));
And in laravel view
#foreach($alldata ?? [] as $key => $value)
#if($key == 'data')
#foreach(json_decode($value->data) ?? [] as $innerKey => $innerValue)
{{ $innerKey }} - {{ $innerValue}} <br>
#endforeach
#else
{{ $key }} - {{ $value }} <br>
#endif
#endforeach

I have an import feature where users can import records from a .csv file. It works fine if the user is importing a file with multiple records but if one tries to import a .csv that has only one record it throws an error, "Invalid argument supplied for foreach()" and spits out this reference code for the error.
<?php $__currentLoopData = $line; $__env->addLoop($__currentLoopData); foreach($__currentLoopData as $field): $__env->incrementLoopIndices(); $loop = $__env->getLastLoop(); ?>
As stated this error only occurs when there is a single record in the import .csv, if one were to add additional records to the .csv the import feature the process works fine.
Here is the blade's foreach code, what's going on?
<table class="table">
#if (isset($headers))
<tr>
#foreach ($headers as $field)
<th>{{ $field }}</th>
#endforeach
</tr>
#endif
#if($lines)
#foreach ($lines as $line)
<tr>
#foreach ($line as $field)
<td>{{ $field }}</td>
#endforeach
</tr>
#endforeach
#endif
<tr>
#foreach ($headers as $key => $header)
<td>
<select name="fields[{{ $key }}]">
<option value=''>Please select</option>
#foreach ($fillables as $k => $fillable)
<option value="{{ $fillable }}"
#if (strtolower($header) === strtolower($fillable)) selected #endif>{{ $fillable }}</option>
#endforeach
</select>
</td>
#endforeach
</tr>
</table>
Here is the controller
public function parse(Request $request)
{
$file = $request->file('csv_file');
$request->validate([
'csv_file' => 'mimes:csv,txt',
]);
$path = $file->path();
$hasHeader = $request->input('header', false) ? true : false;
$reader = new SpreadsheetReader($path);
$headers = $reader->current();
$lines = [];
$lines[] = $reader->next();
$lines[] = $reader->next();
$filename = Str::random(10).'.csv';
$file->storeAs('csv_import', $filename);
$modelName = $request->input('model', false);
$fullModelName = 'App\\'.$modelName;
$model = new $fullModelName();
$fillables = $model->getFillable();
$church_id = $request->input('church_id');
$interest_tags = $request->input('interest_tags');
if ($modelName == 'Interest') {
$custom_fields = CustomField::where('created_by_team_id', $church_id)->pluck('name')->toArray();
if (! empty($custom_fields)) {
$fillables = array_merge($fillables, $custom_fields);
}
}
$is_adding_new_religious_background = $request->input('is_adding_new_religious_background', false) ? true : false;
$redirect = url()->previous();
return view(
'csvImport.parse_import',
compact('headers', 'filename', 'fillables', 'church_id', 'interest_tags', 'hasHeader', 'modelName', 'lines', 'redirect', 'is_adding_new_religious_background')
);
How does one modify this so that it functions for both single record and multi-record imports?
I think you have to check the second #foreach in your blade template. You need to check if if $line is empty before loop.
When i am passing the below in view blade shows the entire Json structure fetching from mongo.
{!! $fees !!}
output :
[{"_id":"5e04a06ca445f78401a16d0a","University":[{"fees":"$200"},{"month":"June"}]}]
Now how to fetch the nested content.I want to show Fees = $200 and Month = June in the blade
Tried like this but result is 'blank' on the blade without any error. Is there any issue with the nested open/closing :[, which is just after 'University:' in the above JSOn input. Please suggest
#foreach ($fees as $value)
{{$content[] = $value->['University'] }}
#foreach ($content as $key)
<h1>{{ $key['fees'] }}</h1>
<h1>{{ $key['month'] }}</h1>
#endforeach
#endforeach
My earlier steps are given here :
Laravel not fetching result from mongodb
Edit(1) :
I tried like this so the structure on blade view.
<?php
$get_result = json_decode($fees, true);
#$get_result = implode(",", array_flatten($get_result));
#print_r($get_result);
#$get_result2 = json_encode($get_result, true);
echo "</br>";
print_r($get_result)
?>
output :
Array ([0] => Array ([_id] => 5e04a06ca445f78401a16d0a [University]
=> Array ([0] => Array ( [fees] => $200 ) [1] => Array ( [month] => June ) )))
Also,
<?php
echo htmlentities (print_r (json_encode ($fees), true));
?>
output:
"[{\"_id\":\"5e04a06ca445f78401a16d0a\",
\"University\":[{\"fees\":\"$200\"},{\"month\":\"June\"}]}]"
Also from Controller i tried as below:
..
public function getFees()
{
# database fetch test (with any one of the db query)
$fees = Finance::all();
$fees = Finance::where(['University.month' => 'June'])->get()->toArray();
$fees = Finance::where('University.month', 'June')->first();
$fees = Finance::where('University.month', 'June')->get();
# Return test (with any one of the return)
return view('tables')->with('fees', json_encode($fees, true));
return view('tables', compact('fees'));
return view('tables')->with(compact('fees'));
return view('tables')->with('fees', $fees);
}
..
Edit(2) :
in view blade i tried as below but getting exception as : Trying to get property 'fees' of non-object
<?php
$fees = json_decode($fees, true);
#echo "</br>";
#print_r($fees)
?>
#foreach ($fees[0] as $value)
#php $content = $value->University #endphp // or without #
#foreach ($content as $key)
<h1>{{ $key['fees'] }}</h1>
<h1>{{ $key['month'] }}</h1>
#endforeach
#endforeach
Edit(3) as per suggestion by Chandan.
<?php
$fees = json_decode($fees);
$univ = $fees[0]->University;
//print_r($univ);
foreach ($univ as $key => $value)
{
foreach($univ[$key] AS $k =>$v)
{
echo $k." " .$v;
}
}
?>
output :
fees $200month June
only thing the output is merges without comma separated.
Can I show them as below
fees = $200
month = June
or as a html
<td>{{$k}}</td><td>{{$v}}</td>
You can try this:
$fees = json_decode($fees);
$univ = $fees[0]->University;
//print_r($univ);
foreach ($univ as $key => $value) {
foreach($univ[$key] as $k =>$v){
echo $k .'= '.$v.' ';
}
}
It should be working as below:-
#foreach ($fees as $value)
{{$content[] = $value->['University'] }}
#if($content->['fees']!==null)
<h1>{{ $content['fees'] }}</h1>
#else
<h1>-</h1>
#endif
#if($content->['fees']!==null)
<h1>{{ $content['fees'] }}</h1>
#else
<h1>-</h1>
#endif
#endforeach
I'm using Laravel framework.
I've got a table with some JSON I want to iterate over, I've cast the table to an array. This is the format;
{"Height": "#m", "Width": "#m", "Weight": {"now": "#kg", "previous": "#kg"}}
My controller returns the view;
$person = Person::find($ID);
$data = $person->tableJson;
return view('person.person_details', compact('person', 'data'));
And in the view itself:
#foreach ($data as $value)
Width: {{ $value->tableJson['Width'] }} <br>
Height: {{ $value->tableJson['Height'] }} <br>
Weight (now): {{ $value->tableJson['Weight']['now'] }} <br>
Weight (previous): {{ $value->tableJson['Weight']['previous'] }} <br>
<hr>
#endforeach
I have that working. The thing is I want to replace the hard coded titles (Width, Height, etc) with the keys in the JSON itself. That way I can (hopefully) dynamically populate a table without knowing what the JSON contains.
When looping your $data use actual keys in that:
$data = [0: ["Height" => "#m", "Width" => "#m", "Weight" => ["now" => "#kg", "previous" => "#kg"]]];
foreach ($data as row) {
foreach ($row as $header => $val) {
if (is_string($val)) {
echo "{$header}: {$val}<br/>";
} else {
foreach ($val as $type => $subVal) {
echo "{$header} ($type): {$subVal}<br/>";
}
}
}
echo "<hr/>";
}
I am trying to convert this PHP code:
<?php
foreach ($arr as $v) {
echo '<tr><td>' . $v['bookTitle'] . '</td><td>';
$ar = array();
foreach ($v['authors'] as $key => $value) {
**$ar[] = '' . $value . '';**
}
echo implode(' , ', $ar) . '</td></tr>';
}
?>
into Laravel code, but have problems
#foreach ($arr as $v)
<tr><td> {{ $v['bookTitle'] }}</td><td>
<?php $ar = array(); ?>
#foreach ($v['authors'] as $key => $value)
***$ar[] = . $value . ;*** //{{ Html::link("all?authorID= $key", "$value")}}
#endforeach
{{implode(' , ', $ar)}}</td></tr>
#endforeach
Can someone please help me with this?
#foreach ($arr as $v)
<tr><td> {{ $v['bookTitle'] }}</td><td>
#php $ar = array(); #endphp
#foreach ($v['authors'] as $key => $value)
#php $ar[]; #endphp = {{ Html::link("all?authorID= $key", "$value")}}
#endforeach
{{implode(' , ', $ar)}}</td></tr>
#endforeach
FatalErrorException
Cannot use [] for reading
Your mistake is at this line. The $val is not exist as your are make each object in loop to $value variable
$ar[] = . $val . ;
Secondly, the blade syntax is like below. Refer to Docs for detail usage.
#foreach ($v['authors'] as $key => $value)
<td>{{ $value }}</td>
#endforeach
Note: Please keep the long code in controller instead of routes/web.php
As you're using Larvel 5.4.x, you can simply do the following and not have to re-write it using blade:
#php
foreach ($arr as $v) {
echo '<tr><td>' . $v['bookTitle'] . '</td><td>';
$ar = array();
foreach ($v['authors'] as $key => $value) {
$ar[] = '' . $value . '';
}
echo implode(' , ', $ar) . '</td></tr>';
}
#endphp
Albeit it's not the best solution, but, until you can move this logic into the controller and not have it within the view, it might be a good interim solution.
If you open up the following link for Control Structures within the Laravel documentation: https://laravel.com/docs/5.4/blade#control-structures and scroll down to the heading named "PHP" it should give you everything you need.
how can I make sure I use more foreach in my blade, without the content repeating more than once?
$review = Review::orderBy('created_at', 'desc')->paginate(9);
$info_games = array();
$games = array();
foreach ($review as $value) {
$info_games[] = InfoGames::where('id_game', $value->id_game)->first();
$games[] = Games::where('id', $value->id_game)->first();
}
return view('front.pages.review.list', compact('review','info_games','games'));
and my blade:
#foreach ($review as $value)
#foreach ($info_games as $info_game)
<div>
<img src="https://gamelite.net/{{$info_game->image}}">
<p>{!! str_limit($value->body, 150) !!}</p>
</div>
#endforeach
#endforeach
{!! $review->render() !!}
use array_filter($array) . It will return unique .
in your case
$info_games = array_filter($info_games);
