Add a checkbox in the admin product page (Prestashop) - prestashop-1.7

Question

I have created a module to add different fields in the admin of the product sheet and I have a registration problem for the checkboxes my other input works very well. I don't see where the problem is coming from. Here is my product class:
<?php
class Product extends ProductCore
{
public $solde_display;
public $only_marketplace;
public $on_vp;
public $boost_product;
public $price_market;
public $tagmodele;
public function __construct($id_product = null, $full = false, $id_lang = null, $id_shop = null, Context $context = null)
{
parent::__construct($id_product, $full, $id_lang, $id_shop, $context);
// Boolean
self::$definition['fields']['solde_display'] = array('type' => self::TYPE_BOOL);
self::$definition['fields']['only_marketplace'] = array('type' => self::TYPE_BOOL);
self::$definition['fields']['on_vp'] = array('type' => self::TYPE_BOOL);
self::$definition['fields']['boost_product'] = array('type' => self::TYPE_BOOL);
// Text
self::$definition['fields']['price_market'] = array('type' => self::TYPE_FLOAT, 'validate' => 'isPrice');
self::$definition['fields']['tagmodele'] = array('type' => self::TYPE_STRING);
}
}
My template:
<div class="m-b-1 m-t-1">
<h2>{l s='Champs supplémentaires (Générale)' mod='overrideoptions'}</h2>
<div class="form-group">
<div class="col-lg-12 col-xl-5">
<div class="checkbox">
<label for="on_vp">
<input type="checkbox" name="on_vp" id="on_vp" value="1" {if $on_vp}checked="checked"{/if}>
Produit en Vente Privée
</label>
</div>
</div>
<div class="col-lg-12 col-xl-5">
<div class="checkbox">
<label for="solde_display">
<input type="checkbox" name="solde_display" id="solde_display" value="1" {if $solde_display}checked="checked"{/if}>
Solde display
</label>
</div>
</div>
<div class="col-lg-12 col-xl-5">
<div class="checkbox">
<label for="only_marketplace">
<input type="checkbox" name="only_marketplace" id="only_marketplace" value="1" {if $only_marketplace}checked="checked"{/if}>
Disponible uniquement en Place de marché !
</label>
</div>
</div>
<div class="col-lg-12 col-xl-5">
<div class="checkbox">
<label for="boost_product">
<input type="checkbox" name="boost_product" id="boost_product" value="1" {if $boost_product}checked="checked"{/if}>
Boost Product (Google Shopping)
</label>
</div>
</div>
</div>
<div class="form-group">
<label for="tagmodele">Tag modele</label>
<input type="text" class="form-control" name="tagmodele" id="tagmodele" placeholder="Tag modele" value="{$tagmodele}">
</div>
</div>
the Tag model registers very well except the checkbox.
Thanks for your help

Maybe too late but if it can help someone else...
You need to override the following file override/controllers/admin/AdminProductsController.php and add the logic to save your checkboxes such as
class AdminProductsController extends AdminProductsControllerCore
{
protected function copyFromPost(&$object, $table)
{
parent::copyFromPost($object, $table);
$object->solde_display = (int)Tools::getValue('solde_display');
$object->only_marketplace = (int)Tools::getValue('only_marketplace');
[...]
}
}
