我正在使用CodeIgniter，它与Bootstrap一起构建一个网站，该网站有一个联系人页面。
我无法对PHP/FormHelper构建的文本字段进行样式化，因为我不确定在哪里使用标记，我尝试过的每个解决方案都会导致额外的文本字段，或者只显示插件，或者什么都没有。
控制器：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Welcome extends CI_Controller {
/**
* Index Page for this controller.
*
* Maps to the following URL
* http://example.com/index.php/welcome
* - or -
* http://example.com/index.php/welcome/index
* - or -
* Since this controller is set as the default controller in
* config/routes.php, it's displayed at http://example.com/
*
* So any other public methods not prefixed with an underscore will
* map to /index.php/welcome/<method_name>
* @see http://codeigniter.com/user_guide/general/urls.html

protected $sendEmailTo = 'you@you.com'
protected $subjectLine = ""; // actually set on line 39.
// views
protected $formView = 'contact';
protected $successView = 'contact_success';
protected $headerView = ''; //null to disable

{
$this->load->library('form_validation');
$this->load->helper('url');
$this->subjectLine = "Contact form response from " . $_SERVER['HTTP_HOST'];
$this->form_validation->set_rules('name', 'Your name', 'trim|required');
$this->form_validation->set_rules('email', 'Your Email', 'trim|required|valid_email');
$this->form_validation->set_rules('message', 'Message', 'trim|required|xss_clean');
if($this->form_validation->run() == FALSE) {
// show the form
if ($this->headerView) { $this->load->view($this->headerView,$this->data); }
$this->load->view($this->formView,$this->data);
if ($this->footerView) { $this->load->view($this->footerView,$this->data); }
} else {
// success! email it, assume it sent, then show contact success view.
$this->load->library('email');
$this->email->from($this->input->post('email'), $this->input->post('name'));
$this->email->to($this->sendEmailTo);
$this->email->subject($this->subjectLine);
$this->email->message($this->input->post('message'));
$this->email->send();

视图：

<?php echo validation_errors(); ?>

我想使用的示例引导CSS：
<div class="input-group">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
首先，您应该在php标记之外构建标记，并只使用php来回显各个输入，您可以将所需的属性作为数组参数传递给form_input()，更多信息请点击此处。
示例：
<div class="input-group">
<span class="input-group-addon">@</span>
<?php echo form_input(array("class"=>"form-control","placeholder"=>"Username"))?>
</div>
表单的codeigniter+bootstrap最棒的地方是，一旦设置了一些配置默认值，你就不必考虑它了。进行一些配置来保存bootstrap代码，并使用codeigniter表单助手为表单字段所需的代码创建数组。这样一来，所有重要的事情都会发生在配置文件中，并且视图非常简单。
// in config file -- this is bootstrap code that is repeated over and over
// so i just make some quick configs to hold the html code
$config['btcgroup'] = '<div class="control-group">';
$config['btclabel'] = array(
'class' => 'control-label'
);
$config['c2divs'] = '</div></div>';
// quick form field example
$config['spnam01'] = 'Shipping First Name';
$config['spary01'] = array(
'name' => 'sp01',
'maxlength' => '60',
'size' => '20',
'class' => 'input-medium',
'placeholder'=> 'First name'
);
$config['sphelp01'] = '<p class="help-block"> Required Field </p>';
// and put it together in the view for form field sp01
echo $btcgroup.form_label($spnam01.$formreq, 'sp01',$btclabel ).$btcontrols.form_input($spary01,set_value('sp01')).form_error('sp01');
echo $c2divs;
没有html代码来构建表单。一旦您有了自己喜欢的模板，我们就不会尝试混合php和html-您可以非常快速地创建表单。（注意，这个例子可能缺少一些东西，但它应该让你开始）
