在下面的codeigniter代码中没有在文本框中输入数据并提交它。它应该抛出表单验证。在我的情况下，只有表单验证不会抛出它是必需的，除了email.Pls帮助我解决问题。 控制器：
function create_member()
{
$this->load->library('form_validation');
// field name, error message, validation rules
$this->form_validation->set_rules('name', 'Name', 'trim|required');
$this->form_validation->set_rules('college_name', 'college_name', 'trim|required');
$this->form_validation->set_rules('email_address', 'Email Address', 'trim|required|valid_email');
$this->form_validation->set_rules('phone_number', 'Phone Number', 'trim|required');
$this->form_validation->set_rules('address', 'address', 'trim|required');
$this->form_validation->set_rules('message', 'message', 'trim|required');
$this->load->helper('date');
if($this->form_validation->run() == FALSE)
{
$this->load->view('contact_view');
}
else
{
$this->load->model('contact_model');
if($query = $this->contact_model->create_member())
{
$this->load->view('contact_view');
redirect('contact', 'refresh');
}
}
}
}
查看：
<?php
echo form_open('contact/create_member');
echo form_input('name', set_value('name', ' Name'));
echo form_input('email_address', set_value('email_address', 'Email Address'));
echo form_input('college_name', set_value('college_name', 'college_name'));
echo form_input('address', set_value('address', 'address'));
echo form_input('phone_number', set_value('phone_number', 'phone_number'));
echo form_textarea('message', set_value('message', 'message'));
echo form_submit('submit', 'Submit');
?>

在您的视图中，您已在这些输入中设置了值。如果规则仅为form validation，则required将返回true。您不应该为这些输入设置默认值，但使用placeholder属性显示消息，而输入字段没有值。
您的视图中还有另一个问题。你的表格没有结束。
您可以在echo form_close();
form_submit

在视图中你应该添加这一行
<?php echo validation_errors(); ?>
你的代码
echo validation_errors(); // line to display error
echo form_open('contact/create_member');
echo form_input('name', set_value('name', ' Name'));
echo form_input('email_address', set_value('email_address', 'Email Address'));
echo form_input('college_name', set_value('college_name', 'college_name'));
echo form_input('address', set_value('address', 'address'));
echo form_input('phone_number', set_value('phone_number', 'phone_number'));
echo form_textarea('message', set_value('message', 'message'));
echo form_submit('submit', 'Submit');
