Question

我有这个表格

<form method="post" action="{$urls.base_url|escape:'htmlall':'UTF-8'}index.php?fc=module&module=cdesigner&controller=storedata" id="form-submited">
        <input type="hidden" name="link" id="cd-link">
        <input type="hidden" name="id" id="cd-id">
        <input type="hidden" name="output" id="cd-output">
        <input type="hidden" name="pret" id="cd-pret" value="100">
</form>

和此storedata.php

class CdesignerStoredataModuleFrontController extends ModuleFrontController
{
    public function init()
    {
        $this->page_name = 'storedata'; // page_name and body id
        parent::init();
    }

    /** Init Function Controller **/
    public function initContent()
    {
        parent::initContent();

        if( !is_numeric(Tools::getValue('output')) )
            exit();

        $output = (int)Tools::getValue('output');


        $pret = (int)Tools::getValue('pret'); // this is my edit

        mysql_query("UPDATE ps_customized_data SET price=24 WHERE id_customization=82"); // until here


        $link = filter_var(Tools::getValue('link'), FILTER_SANITIZE_SPECIAL_CHARS);
        $html = filter_var(Tools::getValue('id'), FILTER_SANITIZE_SPECIAL_CHARS);

        $myfile = fopen( dirname(__FILE__).'/../../views/img/files/tpl/tp_'.$output.'.html', "w") or die("Unable to open file!");
        fwrite($myfile, $html);
        fclose($myfile);

        echo '
            <script>
                document.location = "'.$link.'";
            </script>
        ';

        exit();
    }
}

我正在学习php，我不是专业人士。我想用<input type="hidden" name="pret" id="cd-pret" value="100">

的值更新sql表'ps_customized_data'列'price'

我认为我必须在storedata.php上调用sql

Answer 1

要在Prestashop中执行SQL查询，应使用Best Practices of the Db Class。不要使用mysql_query。

// Updating values
Db::getInstance()->update($table, $data, $where = '', $limit = 0, $null_values = false, $use_cache = true, $add_prefix = true)

以您的情况

$data = array(
    'price' => $pret
);
Db::getInstance()->update('ps_customized_data', $data, 'id_customization = 82');

从表单获取值并更新表sql
