Hi, I was playing with editor and I wanted to count the number of row in a table, so I made this

function onStart(){
$this["invitati"] = DB::table('invitati')
    ->selectRaw('COUNT(*) as presenti')    
    ->get();
}

and I want to print the value of invitati, but if I try to do

<div class="grid container">
<div class="col span-2"></div>
    <div class="col span-10">
        <p>{{ invitati }}</p>
    </div>
</div>

It returns me: An exception has been thrown during the rendering of a template ("Array to string conversion").

The variable should contain the value "2", how can I print it?

Try DB::table('invitati')->count()

Thank you :)

Another question: if I recover data from a database using

$res = DB::table('invitati')->get();

it returns me an array of object. How can I do to extract value from it? I tried to do as say in this post but none of the solutions suggested seems to work.

EDIT:

Solved in this way:

DB::setFetchMode(PDO::FETCH_ASSOC);
$res = DB::table('invitati')->get();
DB::setFetchMode(PDO::FETCH_CLASS);

but still receive the same error as before (mysql_fetch_array() expects parameter 1 to be resource, array given)

EDIT 2.0

I solved making

    $nomi = array();
$cognomi = array();
$partec = array();
$regalo = array();

foreach($res as $inv)
{
    $nomi[] = $inv['nome'];
    $cognomi[] = $inv['cognome'];
    $partec[] = $inv['partecipazione'];
    $regalo[] = $inv['regalo'];
}

$this['nomi'] = $nomi;
$this['cognomi'] = $cognomi;
$this['partec'] = $partec;
$this['regalo'] = $regalo;

I know that probably this code sucks but it do what I want and is enought for now

This should do what you need

DB::table('invitati')->get()->toArray();

Thank you :D

Hi, I'm trying to do something similar except instead of printing I'm trying to push the select results from a table of a specific database to the default database of my plugin through a routes but doing this I'm getting a Undefined index: id_couleur so something must be wrong in how my array is defined

<?php

use Macro\Mes\Models\Couleur;
use Illuminate\Support\Facades\Db;

Route::get('hello', function () {

$fact = Db::connection('fact')
  ->table('glo_couleur')
  ->select(['id_couleur','tag_couleur','desc_couleur_fr','desc_couleur_en','ref_html'])
  ->where('obsolete','=', 0)
  ->orderBy('tag_couleur', 'ASC')
  ->get()
  ->toArray();

Couleur::create([
  'id_couleur' => $fact['id_couleur'],
  'tag_couleur' => $fact['tag_couleur'],
  'desc_couleur_fr'=> $fact['desc_couleur_fr'],
  'desc_couleur_en'=> $fact['desc_couleur_en'],
  'ref_html' => $fact['ref_html'],
]);
  return "Colors created";
});

It probably means your select statement is returning nothing from from the database.

if (empty($fact)) {
    return "Nothing to do";
}
