我如何 return 将安装错误返回到 Prestashop 1.7 中的模块管理器?
How can I return an install error back to the Module Manager in Prestashop 1.7?
我正在尝试调试我的模块安装,其中有几次它会根据某些字段 return false。根据哪个失败,我想显示一个输出。我试过:
\Tools::displayError('This worked.');
array_push($this->context->controller->errors, $this->l('This worked.'));
我的安装是这样的:
public function install() {
\Tools::displayError('This worked.');
array_push($this->context->controller->errors, $this->l('This worked.'));
return (parent::install() && false); // Force a fail to test
}
然而,我似乎得到的只是:
Unfortunately, the module did not return additional details.
我已经在 Internet 上查找修复程序,但 have only come across outdated ones。任何帮助将不胜感激。
编辑:我的构造函数将 need_instance 设置为 1:
public function __construct() {
...
$this->need_instance = 1;
...
parent::__construct();
...
}
更新:为了帮助未来的观众,Db
class 的 insert
功能自动将前缀添加到 table 名称。删除 self::DB_PREFIX
解决了这个问题。
return \Db::getInstance()->insert('iezon_portfolio', array(
'img_link' => pSQL($img),
'title' => pSQL($title),
'description' => pSQL($description),
'company_name' => pSQL($company),
'company_url' => pSQL($company_url),
'testimonial' => pSQL($testimonial),
'is_favourite' => (int) $fav,
));
尝试这样的事情:
public function install()
{
if ($this->checkForErrors()) {
$this->_errors[] = $this->l('Error message');
return false;
}
...rest of the code...
}
