PHPMailer exception error
提问by Adamantus
I've written my own Code Igniter model for sending emails. All was fine until recently when I started to get this error:
我已经编写了自己的 Code Igniter 模型来发送电子邮件。一切都很好，直到最近我开始收到此错误：
Fatal error: Cannot redeclare class phpmailerException in /home/mysite/public_html/subdir/application/libraries/phpmailer/class.phpmailer.php on line 2319
致命错误：无法在第 2319 行的 /home/mysite/public_html/subdir/application/libraries/phpmailer/class.phpmailer.php 中重新声明类 phpmailerException
I'm using:
我正在使用：
CodeIgniter 2 PHPMailer 5.1
CodeIgniter 2 PHPMailer 5.1
I've tried the following to resolve it:
我尝试了以下方法来解决它：
- Added "$mail->SMTPDebug = 0" to turn off errors.
- Added: "$mail->MailerDebug = false;"
- Modified the PHPMailer to only show errors when SMTPDebug is turned on.
- Looked for and removed any echo statements
- Added try / catch blocks Tried adding / removing: $mail = new PHPMailer(true);
- 添加了“$mail->SMTPDebug = 0”以关闭错误。
- 添加：“$mail->MailerDebug = false;”
- 修改 PHPMailer 以仅在打开 SMTPDebug 时显示错误。
- 查找并删除了所有 echo 语句
- 添加了 try/catch 块尝试添加/删除：$mail = new PHPMailer(true);
Here is my controller method (company/contact) which calls my model (message_model):
这是我的控制器方法（公司/联系人），它调用我的模型（message_model）：
function contact()

$this->options->privatekey = $this->config->item('recaptcha_private');
//Form validation
$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
$this->form_validation->set_rules('name_field','Name of problem','trim|required|min_length[3]|max_length[100]');

//Set result.
if($result==-1)
$this->session->set_flashdata('result', ucfirst($this->options->task).' was not '.$this->options->change.' because of a database error.');
elseif($result==0)

//Redirect to completed controller.
redirect('completed');
}
//Validation failed or first time through loop.

}
Here is my model's method to send the emails. It used to work but without any changes I can think of now I get an exception error:

if (!class_exists("phpmailer")) {
require_once('PHPMailer_5.2.2/class.phpmailer.php');
}
This Code will clear this issue 100%..
本守则将 100% 清除此问题..

Basically one of two things is happening:
基本上发生了两件事之一：
You are "including" your PHP code twice somewhere, causing the 2nd time to generate the redeclaration error
You are using "phpmailerException" somewhere else, besides your model. Have you tried to do a "find all" in your IDE for ALL calls to "phpmailerException" - perhaps you used this name in another area for another exception?
您在某处“包含”两次 PHP 代码，导致第二次生成重新声明错误
除了模型之外，您还在其他地方使用“phpmailerException”。您是否尝试在您的 IDE 中为所有对“phpmailerException”的调用执行“全部查找”——也许您在另一个区域使用了这个名称作为另一个异常？

require_once("class.phpmailer.php") is better.
require_once("class.phpmailer.php") 更好。
Mukesh is right that require_once will solve Sift Exchanges answer #1. However, there is not need to check if the class exists as require_once does that.
Mukesh 是对的，require_once 将解决 Sift Exchanges 的答案#1。但是，不需要检查类是否存在，因为 require_once 会这样做。
