How do I split string and display it in a table in Laravel Framework? I fetch data from my database that consists of one column but in a string such as { 1234, normal, r4r3r2 }. I want to split it into three different parts/values by commas and display it in a table of three columns.
For now, I only can display the data without splitting the them.
My HomeController:
public function index()
{
$test = Test::all();
return view('home')->with('test', $test);
}
My home.blade.php:
<ol>
#foreach($test as $row)
<li>{{ $row->data }}</li>
#endforeach
</ol>
First explode the $test variable to get Array,
<ol>
#foreach(explode(',',$test) as $row)
<li>{{ $row }}</li>
#endforeach
</ol>
After explode using foreach single key we can access from the array.
I hope it helps.
You can explode you string in blade file like this
#foreach(explode(',', $row->data) as $fields)
<li>{{$fields}}</li>
#endforeach
And using of your model you can also done like this
class Test extends Model
{
public function getDataAttribute()
{
return explode(',', $this->data);
}
}
it's return your data explode with comma separated array.
i'm new in laravel, i have some problem to make database as variable to be shown on blade template,
example i want to get any data from database :
{{$get = DB::table('perangkat')->get()}}
then:
#foreach ($get as $got)
{{$got->jabatan}}
#endforeach
if the result of the $got->jabatan is kepala, But i want the result is Change To "Kepala Desa", How can i do ??
Please Help Mee ...
Write database related stuff in model or controller in a method and pass that value to view. It will be very neat and clear
public function getData(){
$get = DB::table('perangkat')->get();
return view('myblade', ['data' => $get]);
}
In your view
#foreach ($data as $got)
{{$got->jabatan}} Desa
#endforeach
Also can you update where you get Desa .so i can update answer according to that.
Updated
you keep different roles in array and do some think like this
<?php
$role=['a'=>'operator','b'=>'admin'] ; ?>
#foreach ($data as $got)
<?php $result = isset($role[$got->jabatan]) ? $role[$got->jabatan] : null; ?>
{{$result}}
#endforeach
company.php
function showdata{
$sql= "this syntax sql";
}
//show data
$company = new company();
#foreach ($company->showdata() as $got)
{{$got->jabatan}}
#endforeach
I need to check for a name in an array of names but I having trouble passing an array instead of a collection to the in_array() method.
My blade code looks something like this
#foreach($ecn->areas as $area)
{{ $area->area }}:<br>
<ul>
#foreach($area->people as $person)
#if(in_array($person, $ecn->signatures->name ))
<li><del>{{ $person }}</del></li>
#else
<li>{{ $person }}</li>
#endif
#endforeach
</ul>
#endforeach
I know my problem is in the way im trying to access the list of signatures.
#if(in_array($person, $ecn->signatures->name ))
I can access them in another part of the page doing this
#foreach($ecn->signatures as $signature)
{{ $signature->name }}<br>
#endforeach
and everything is fine.
How can I access and pass the list of signatures as an array in this scenario?
If you want to use in_array() version for Laravel Collections then you can use:
$collection->contains($needle)
It woks just like in_array.
If $needle is an integer, an id for example, don't forget to pluck first, like so:
$collection->pluck('id')->contains($needle)
You can use the lists or pluck method on the signatures collection to get a new collection of all the names. From there, you can either use the contains() method on the collection, or you can use the all() method to turn the collection into an array and use in_array directly.
I would suggest doing this outside of the foreach loop, so you're not generating this new collection and array every iteration.
Array:
// controller
$names = $ecn->signatures->lists('name')->all();
// blade
#if(in_array($person, $names))
Collection:
// controller
$names = $ecn->signatures->lists('name');
// blade
#if($names->contains($person))
You can also use contains() with a closure, which would let you get away with not creating an intermediate collection, but it's a little harder to read:
Contains with closure:
// blade
#if($ecn->signatures->contains(function ($key, $value) use ($person) {
return $value->name == $person;
}))
As per Laravel Docs
The get method returns an array of results where each result is an instance of the PHP StdClass object.
So you must convert your stdClass object to a array in your controller itself.
foreach ($ecn->signatures as $signature)
$nameArray[] = $signature->name;
and then you can use in_array in the blade template
#if(in_array($person, $nameArray))
I have a problem with Laravel. So what am I trying to do? I'm trying to get the location from all my examples. This actually works, so as you can see I get the id of all the examples and find the locations of it from another table in my project. The var_dump in the foreach gives what I need. But I need this data outside the foreach, I need to send it to my view afterwards. But the second var_dump, the one outside the foreach only gives the location of the first id.
So my question: is there a way to get the full $locations outside the foreach.
$ids= DB::table('example')
->select('id')
->get();
foreach($ids as $id)
{
$locations = example::find($id->id)->locations()->get();
var_dump($locations);
}
var_dump($locations);
This is my view:
#foreach($examples as $example)
<h1>{{$example->name}}</h1>
#foreach($locations as $location)
{{$location}}
#endforeach
#endforeach
I see al the locations from al the $examples in every $example if I print it like this, I hope you understand my question.
Try this:
// Define locations array
$locations = [];
// Then do the following for each example:
// Define the array for locations of each example outside of the loop
$locations[$example->name] = [];
foreach ($ids as $id) {
// Add each location to the $locations array
$locations[$example->name][] = example::find($id->id)->locations()->get();
}
Or if you want to get a little bit more fancy, you can use array_map instead of foreach:
$locations[$example->name] = array_map(function ($id) {
return example::find($id->id)->locations()->get();
}, $ids);
Then in the view, you simply take out the locations from the right key for each example:
#foreach ($examples as $example)
<h1>{{ $example->name }}</h1>
#foreach ($locations[$example->name] as $location)
{{ $location }}
#endforeach
#endforeach
You don't have to use the $example->name as the key, just make sure it's unique for each example you want to fetch locations for.
I hope this helps.
There is no need to build the $locations array. You can use the relationship in the view just fine.
In your controller:
// whatever your logic is to get the examples
$examples = example::with('locations')->get();
In your view:
#foreach($examples as $example)
<h1>{{$example->name}}</h1>
#foreach($example->locations as $location)
{{$location}}
#endforeach
#endforeach

When I use the following foreach I show the information
#foreach ($subastas as $subasta)
{{$subasta}}
#endforeach
Now I try to use the following code
#foreach ($subastas as $subasta)
#foreach ($subasta->subastas as $sub)
{{$sub}}
#endforeach
#endforeach
And I recieve this error
Trying to get property of non-object (View: C:\xampp3\htdocs\laravel\resources\views\prodcercanos.blade.php)
Any solution for this problem ?
The question is , how I can render the json in laravel ?
The controller to recieve the JSON
public function productoscercanos ($lat,$long){
$subastas = Subasta::all();
$categorias = Categoria::all();
$provincias = Provincia::all();
$cercanos = User::with(array('municipio', 'subastas'))->get();
$coordA = Geotools::coordinate([$lat,$long]);
$output = [];
foreach ($cercanos as $p) {
if(count($p->subastas)>0){
$coordB = Geotools::coordinate([$p->municipio->latitud,$p->municipio->longitud]);
$distance = Geotools::distance()->setFrom($coordA)->setTo($coordB);
$dis = $distance->in('km')->haversine();
$output[$dis] = $p."<p>$dis</p>";
}
}
ksort($output);
return view('prodcercanos')->with('categorias',$categorias)->with('provincias',$provincias)->with('subastas',$output);
}
$json = (your json file);
$subasta = json_decode($json);
then you should be able to use the json as a object now.
Try array syntax in the second foreach loop.
#foreach ($subasta['subastas'] as $sub)
{{$sub}}
#endforeach
Your code is outputting exactly what is defined. First look at how the controller is building the array.
$output[$dis] = $p."<p>$dis</p>";
$p is a User model from the variable $cercanos, appending it to $dis results in it being converted into JSON and added to your output array which your view iterates and outputs.
It looks like you are trying to add the distance to the user and pass it on.
Instead use an Accessor & Mutator to add an extra attribute to your model then pass on the $cercanos list to the view, from there you can render using a for each and grab the value.
#foreach($cercanos as $c)
{{ $c->username }} {{ $c->dis }}
#endforeach
Update
Once you have added your accessor and mutator you will be able to sort using Collections built in method.
$cercanos->sortBy('dis');
