How to call a view based on a condition using a db query

Question

I have 6 views, I want to call a view based on a condition, in my case I'm loading contracts, each contract is within a specific view

• contract_1.blade.php
• contract_2.blade.php
• ...
• contract_6.blade.php

How can I call the view contract_1.blade.php when contract_1 is selected? to explain this more, I have Contract class:

namespace App;

use \DateTimeInterface;
use Carbon\Carbon;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Spatie\MediaLibrary\HasMedia;
use Spatie\MediaLibrary\InteractsWithMedia;
use Spatie\MediaLibrary\MediaCollections\Models\Media;

class Contract extends Model implements HasMedia
{
    use SoftDeletes;
    use InteractsWithMedia;
    use HasFactory;

    public const TYPE_LOCATION_SELECT = [
        'contract_1' => 'Contrat de bail meublée',
        'contract_2' => 'Contrat de bail vide',
        'contract_3' => 'Contrat de bail commercial',
        'contract_4' => 'Contrat de bail saisonnier',
        'contract_5' => 'Contrat de bail professionnel',
        'contract_6' => 'Contrat de bail d\'habitation',
    ];

    public $table = 'contracts';

    protected $appends = [
        'attachment',
    ];

    protected $dates = [
        'start_rent_date',
        'end_rent_date',
        'created_at',
        'updated_at',
        'deleted_at',
    ];

    protected $fillable = [
        'user',
        'type_location',
        'full_name',
        'dob',
        'identity',
        'address',
        'estate_type_id',
        'estate_location',
        'rent_period',
        'start_rent_date',
        'end_rent_date',
        'equipments',
        'superficie',
        'etage',
        'porte',
        'charges',
        'garantie',
        'total_amount',
        'created_at',
        'updated_at',
        'deleted_at',
    ];

    public function registerMediaConversions(Media $media = null): void
    {
        $this->addMediaConversion('thumb')->fit('crop', 50, 50);
        $this->addMediaConversion('preview')->fit('crop', 120, 120);
    }

    public function estate_type()
    {
        return $this->belongsTo(Estate::class, 'estate_type_id');
    }

    public function getStartRentDateAttribute($value)
    {
        return $value ? Carbon::parse($value)->format(config('panel.date_format')) : null;
    }

    public function setStartRentDateAttribute($value)
    {
        $this->attributes['start_rent_date'] = $value ? Carbon::createFromFormat(config('panel.date_format'), $value)->format('Y-m-d') : null;
    }

    public function getEndRentDateAttribute($value)
    {
        return $value ? Carbon::parse($value)->format(config('panel.date_format')) : null;
    }

    public function setEndRentDateAttribute($value)
    {
        $this->attributes['end_rent_date'] = $value ? Carbon::createFromFormat(config('panel.date_format'), $value)->format('Y-m-d') : null;
    }

    public function getAttachmentAttribute()
    {
        return $this->getMedia('attachment');
    }

    protected function serializeDate(DateTimeInterface $date)
    {
        return $date->format('Y-m-d H:i:s');
    }
}

My generated pdf file is called getpdf.blade.php

{{$contract_type = \App\Contract::where(['location_type' => $contract->location_type])}}
@if ($contract_type == contract_1)
@extends('layouts.contract_1')
@else
extends('layouts.contract_2')
@endif

I'm getting this error:

ErrorException htmlspecialchars() expects parameter 1 to be string, object given (View: /var/www/app/resources/views/admin/contracts/getpdf.blade.php)

I'm not sure where the mistake is.

Answer 1

Your error is on the first line, you are literall doing {{ $variable = object }} but that object is not stringable, so it does not know how to turn the object to a string.

So, this:

{{$contract_type = \App\Contract::where(['location_type' => $contract->location_type])}}

should be:

@php
$contract = \App\Contract::where(['location_type' => $contract->location_type])->first();
@endphp

And then, the if:

@if ($contract_type == contract_1)

should be:

@if ($contract->type_location == "contract_1")

Have in mind that ->first() could return no object (null), so doing $contract->type_location could throw an error. In that case, I would recommend to check how to solve those types of issues depending what PHP version you have.
