I have a query which show information from two tables in foreach loop on my blade view. This is the controller
public function details( $id ){
$details = Item::find($id)->report;
return view('details', compact('details'));
}
On my view I have
#foreach($details as $itemDetails)
....
#endforeach
Is it possible to show before foreach single variable from this query like?
{{ $details->id }}
#foreach($details as $itemDetails)
....
#endforeach
I want to get the $id.
Yes you can, try this:
$details[0]->id;
Try to understand the concept, every time you use model to get some data it returns an array of object like:
array(
0 => stdClass Object,
1 => stdClass Object,
and so on
)
So to access the data we use foreach() loop or you can directly call the index as done above.
But if you are calling index directly then put a check for its existence using isset()
I am trying to fetch data from a table by using a custom class .But it says htmlentities() expects parameter 1 to be string.
This is My DateTimeFormat Class .Here vitals is a table.which have vita_name attribute.
public static function get_vital_details($vital_id)
{
$result = DB::table('vitals')
->select('vita_name')
->where(['id' => $vital_id])
->get();
return $result;
}
This is the view i am trying to access the data .
<?php $vitalsinfo=DateTimeFormat::get_vital_details($vitaldetails->vital_id) ?>
#foreach($vitalsinfo as $vitalsinfo)
{{$vitalsinfo}}
#endforeach
i Am new to laravel .Any suggestions would be more than welcome. Thank You
You're trying to dipslay object as string, so try to use first() instead of get() to get just one object instead of collection:
$result = DB::table('vitals')
->select('vita_name')
->where(['id' => $vital_id])
->first();
And do just this (instead of #foreach construction) to display property of an object:
{{ $vitalsinfo->vita_name }}
I am simply (for my own testing purposes) trying to take data from a collection and pass it to a view. I am using Laravel.
I am getting my data from the GitHub API, converting it and putting it in a collection. From here it's passed to a view, but I can't output each individual field.
Here's some code:
$httpClient = new Client();
$response = $httpClient->get('https://api.github.com/users/<randomuser>');
$json = json_decode($response->getBody(), true);
$collection = collect($json);
return view('github')->with('github', $collection);
and my Blade file is
#foreach ($github as $git)
{{ $git }}
#endforeach
Now I thought it would be something as simple as {{ $git->email }} to output it, but I don't think the array keys are been sent (?)
Can anybody point me in the right direction of where I am going wrong?
Thanks in advance.

Because it's a key => val array, you should loop it as such...
#foreach ($github as $key => $val)
Key: {{ $key }} ~~ Value: {{ $val}} <br />
#endforeach
However if you are looking to just grab the email, use the Collection's get method.
$email = $github->get('email')
Simple use get() method in your blade
$github->get('login')
Try this,
in your controller use View and in function
$data['github_data'] = $collection;
return view('github', $data);
and in blade
{{ dd($github_data) }}
When you are working with Laravel try to check if you have the correct structure before trying to manipulate it.
In this case, check that:
You are getting what you expect in $response after call $httpClient->get (if you are using Guzzle).
You have a $json with the structure that you expect to receive.
You have a Collection instance after calling collect().
You can use dd() or var_dump() to see what data structure you have. What´s probably happening is that you don´t have the structure that you think.
I need to check for a name in an array of names but I having trouble passing an array instead of a collection to the in_array() method.
My blade code looks something like this
#foreach($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))

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');
