Prestashop 1.6.1 如何将输入数据从 tpl 文件中的表单发布到 mysql db？

Question

来自希腊的问候，

我正在尝试将一些输入数据从位于 tpl 文件中的表单发布到我的数据库中的表中。

我尝试了很多方法都没有成功。 （我是 prestashop 模块开发的新手）

提前感谢您的帮助。

我创建表单的文件是： 项目模块.tpl

<h4>{l s='Project Module' mod='projectmodule'}</h4>
<div class="separation"></div>
<form name="text_fields" method="post" action="">
    <table>
        
        <tr>
            <td class="col-left">
                <label>{l s='First Field:'}</label>
            </td>
            <td>
                {include file="controllers/products/input_text_lang.tpl"
                    languages=$languages
                    input_name='firstfield'
                    input_value=$firstfield}
                <p class="preference_description"></p>
            </td>
        </tr>

        <tr>
            <td class="col-left">
                <label>{l s='Second Field:'}</label>
            </td>
            <td>
                {include file="controllers/products/input_text_lang.tpl"
                    languages=$languages
                    input_name='secondfield'
                    input_value=$secondfield}
                <p class="preference_description"></p>
            </td>
        </tr>

        <tr>
            <td class="col-left">
                <label>{l s='Third Field:'}</label>
            </td>
            <td>
                {include file="controllers/products/input_text_lang.tpl"
                    languages=$languages
                    input_name='thirdfield'
                    input_value=$thirdfield}
                <p class="preference_description"></p>
            </td>
        </tr>

        <tr>
            <td><input type ="submit" name = "submit_form" value = "Submit" /></td>
        </tr>
    </table>
</form>

我的主要 php 文件是： 项目模块.php

public function install()
    {

        include(dirname(__FILE__).'/sql/install.php');

        return parent::install() &&
            $this->registerHook('displayAdminProductsExtra');

        
    }

    public function uninstall()
    {

        include(dirname(__FILE__).'/sql/uninstall.php');

        return parent::uninstall();
    }

    public function prepareNewTab()
    {
        
        $this->context->smarty->assign(array(
            'languages' => $this->context->controller->_languages,
        ));

    }
    
    public function hookDisplayAdminProductsExtra($params)
    {
        if (Validate::isLoadedObject($product = new Product((int)Tools::getValue('id_product'))))
        {
            $this->prepareNewTab();
            return $this->display(__FILE__, 'projectmodule.tpl');
        }
    } 

我在数据库中创建表的文件是：install.php

$sql = array();

$sql[] = 'CREATE TABLE IF NOT EXISTS `' . _DB_PREFIX_ . 'projectmodule` (
    `id_projectmodule` int(11) NOT NULL AUTO_INCREMENT,
    PRIMARY KEY  (`id_projectmodule`),
    `firstfield` varchar(255) NOT NULL,
    `secondfield` varchar(255) NOT NULL,
    `thirdfield` varchar(255) NOT NULL    
) ENGINE=' . _MYSQL_ENGINE_ . ' DEFAULT CHARSET=utf8;';

foreach ($sql as $query) {
    if (Db::getInstance()->execute($query) == false) {
        return false;
    }
}

标准方式：

你必须在你的模块中添加“actionProductUpdate”钩子。

您还必须有您的自定义对象模型。

public function hookActionProductUpdate($params)
{
    require_once (_PS_MODULE_DIR_ . $this->name .'/models/ProjectModuleCore.php');
    $id_product = (int)Tools::getValue('id_product');
    if($id_product && Tools::getValue('submit_form')) {
        $id = null;
        // Some code to get if exist $id
        $fn = new ProjectModuleCore($id);
        $fn->id_product = $id_product;
        $fn->firstfield = Tools::getValue('firstfield');
        $fn->secondfield = Tools::getValue('secondfield');
        $fn->thirdfield = Tools::getValue('thirdfield');
        $fn->save();
    }
}

在“ProjectModuleCore.php”文件中：

<?php
class iProductFnbCore extends ObjectModel
{
    public $id_product;
    public $firstfield;
    public $secondfield;
    public $thirdfield;

    public static $definition = array(
        'table' => 'projectmodule',
        'primary' => 'id_projectmodule',
        'fields' => array(
            'id_product' =>      array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'required' => true),
            'firstfield' =>              array('type' => self::TYPE_STRING, 'validate' => 'isString'),
            'secondfield' =>         array('type' => self::TYPE_STRING, 'validate' => 'isString'),
            'thirdfield' =>          array('type' => self::TYPE_STRING, 'validate' => 'isString'),
        )
    );
}

注意：这只是一个示例代码，没有验证和...
