Accessing Pivot table data in laravel - sql

Question

I have 3 tables in database named tbl_product_manager, tbl_tags, tbl_categories. tbl_product_manager and tbl_categories are linked to one to one relations and tbl_tags and tbl_product_manager is linked with many to many relations with pivot table tbl_product_tag. I had used eloquent for this. I am able to perform insert and update operation in those tables but I am stuck in viewing data through HTML.
This is my controller code for view:
public function getProducts()
{
$productList = ProductManagementModel::getAllProducts();
//var_dump($productList); die();
$i = 1;
$products = '';
foreach($productList as $product) {
$products .= '<tr class="odd gradeX">';
$products .= '<td>'.$i++.'</td>';
$products .= '<td>'.$product->product_name.'</td>';
$products .= '<td>'.$product->category_name.'</td>';
$products .= '<td>'.$product->product_cost .'</td>';
if($product->is_active=='1') {
$products .= '<td>'.'<a href="javascript:void(0)" class="unpublish-selectedproduct" id="'.$product->id.'" >'.
'<span class="label label-success"><i class="icon-ok"></i></span></a> &nbsp'.'</td>';
} else {
$products .= '<td>'.'<a href="javascript:void(0)" class="publish-selectedproduct" id="'.$product->id.'" >'.
'<span class="label label-warning"><i class="icon-minus-sign"></i></span></a> &nbsp'.'</td>';
}
$products .= '<td>'.$product->updated_at.'</td>';
$products .= '<td>'.
'<i class="icon-pencil"></i> Edit '.
'<a href="javascript:void(0)" class="delete-selectedproduct" id="'.$product->id.'" >'.
'<i class="icon-trash" ></i> Delete</a>'.'</td>';
$products .= '</tr>';
}
return View::make('admin.product_management.list', array('products' => $products));
}
Model of table tbl_product_manager
<?php
use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;
class ProductManagementModel extends Eloquent implements UserInterface, RemindableInterface {
use UserTrait, RemindableTrait;
protected $table = 'product_manager';
public function categories(){
return $this ->hasOne('CategoriesModel','id');
}
public function tag()
{
return $this->hasMany('TagModel','id');
}
public static function getAllProducts(){
return $product = DB::table('product_manager')
->join('categories', 'product_manager.category_id', '=','categories.id')
->select('product_manager.id', 'categories.id','product_manager.*', 'categories.category_name')
->groupby('product_manager.id')
->get();
}
public function tags() {
return $this->belongsToMany('TagModel', 'product_tag', 'product_id', 'tag_id');
}
}
Model of table tbl_tag
<?php
use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;
class TagModel extends Eloquent implements UserInterface, RemindableInterface {
use UserTrait, RemindableTrait;
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'tags';
public function productManagement()
{
return $this->hasMany('productManagementModel');
}
public static function getAlltags()
{
return $tags = DB::table('tags')
->get();
}
public function products() {
return $this->belongsToMany('productManagementModel', 'product_tag', 'tag_id', 'product_id');
}
}
model of pivot table tbl_product_tag
<?php
use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;
class ProductTagModel extends Eloquent implements UserInterface, RemindableInterface {
use UserTrait, RemindableTrait;
protected $table = 'product_tag';
public $limit;
public static function productTags()
{
return $productTag = DB::table('product_tag')
->get();
}
}
I am making the html view in controller itself. I want to use eloquent for to access the data of tbl_tag which is linked with the pivot table and the parent table(tbl_product_manager) is also linked with the pivot table.

You didn't show how are you trying to display tags. Looks like you just to display all tags for each product. In this case, load the data:
$products = ProductManagementModel::with('tags')->get();
And then display it:
#foreach ($products as $product)
{{ $product->name }}
#foreach ($product->tags as $tag)
{{ $tag->name }}
#endforeach
#endforeach
