Question

我无法为我的表单设置if writable表单验证。

我知道codeigniter表单验证是post。我认为这可能会起作用。

如果文件或文件夹不可写，我需要能够显示我的错误chomd 644 or 777

目前已知错误正在显现。

我有表单验证库和表单自动加载。

控制器

我的更新我现在可以收到错误，显示我必须在控制器上添加它。

$this->form_validation->set_rules('cache', '', 'callback_isWritable');

public function isWritable() {
$folder_cache = FCPATH . APPPATH . 'cache';

if (is_writable($folder_cache )) {
return true;
} else {
$this->form_validation->set_message('isWritable', 'Cache Folder ' . '<b>' . $folder_cache . '</b>' . ' is not writable');
return false;
}    
}

您需要创建一个自定义回调来用于此目的。

您需要在与验证码相同的类中创建这样的函数。

//by adding the extra underscore the method is not reachable from the browser
public function _isWritable($filename)
{
    if (! is_really_writable(APPPATH . 'cache')) {
        $this->form_validation->set_message('isWritable', 'Cache Folder is not writable');

        return false;
    }

    //additional if statements to check each of the additional folders...

   return true;
}

然后你只需将它添加到像这样的规则

$this->form_validation->set_rules('saveChecks', '', 'callback__isWritable');

您可以通过执行

输出表单错误

echo form_error('saveChecks');

如果可写表单验证不工作CI
