如何在安装Joomla时显示自定义错误！ 1.6 - 1.7组件？
[英]How to show custom error while installing a Joomla! 1.6 - 1.7 component?
问题描述
I am writing an install script for a Joomla! 
我正在为Joomla编写安装脚本！ 1.7 component. 1.7组件。 How can I modify the install() section of the script so that in case of failure, I can show the user a nicely formatted HTML error? 如何修改脚本的install()部分，以便在出现故障时，我可以向用户显示格式错误的HTML错误？
Currently, I only return false from the install() routine, which results in a cryptic error message: 目前，我只从install()例程返回false ，这会产生一个神秘的错误消息：
Component Install: Custom install routine failure
The component.php file in joomla/installer/adapters/component.php has the following code, which leads me to suspect that I can't change the abort() message. joomla/installer/adapters/component.php的component.php文件具有以下代码，这使我怀疑我无法更改abort()消息。
if ($this->parent->manifestClass && method_exists($this->parent->manifestClass, 'install'))
{
if ($this->parent->manifestClass->install($this) === false) {
// Install failed, rollback changes
$this->parent->abort(JText::_('JLIB_INSTALLER_ABORT_COMP_INSTALL_CUSTOM_INSTALL_FAILURE'));
return false;
}
}
Solution 解
Before returning an error, I can raise an error, that appears nicely in a yellow box. 在返回错误之前，我可以引发错误，该错误在黄色框中很好地显示。
JError::raiseNotice(1, "Error Message <html code>");
return false;
