你怎么写表格?

在您的框架中是否有任何自动构建表单?

例如,假设你有这个字段数组:

$fields = array('name'=>array('type'=>'input',otherparams)
                'desc'=>array('type'=>'textarea',otherparams)
               );

基于字段,您应该像这样制作HTML:

<form>
  Name: <input name="name" type="text">
  Description: <textarea name="desc"></textarea>

//>Submit
</form>

你是手动构建你的html还是有某种自动化?

我使用Yii框架。 php自动生成html。你手工编写了一些HTML,但这是为了观点。视图还具有更改的动态php变量。实际完整的html文档通过调用带有Web地址的控制器放在一起,控制器决定哪些模型需要应用于表单以及放置模型的视图。然后它生成html。

SiteController.php

    <?php

class SiteController extends Controller
{
    /**
     * Declares class-based actions.
     */
    public function actions()
    {
        return array(
            // captcha action renders the CAPTCHA image displayed on the contact page
            'captcha'=>array(
                'class'=>'CCaptchaAction',
                'backColor'=>0xFFFFFF,
            ),
            // page action renders "static" pages stored under 'protected/views/site/pages'
            // They can be accessed via: index.php?r=site/page&view=FileName
            'page'=>array(
                'class'=>'CViewAction',
            ),
        );
    }

    /**
     * This is the default 'index' action that is invoked
     * when an action is not explicitly requested by users.
     */
    public function actionIndex()
    {
        // renders the view file 'protected/views/site/index.php'
        // using the default layout 'protected/views/layouts/main.php'
        $this->render('index');
    }

    /**
     * This is the action to handle external exceptions.
     */
    public function actionError()
    {
        if($error=Yii::app()->errorHandler->error)
        {
            if(Yii::app()->request->isAjaxRequest)
                echo $error['message'];
            else
                $this->render('error', $error);
        }
    }

    /**
     * Displays the contact page
     */
    public function actionContact()
    {
        $model=new ContactForm;
        if(isset($_POST['ContactForm']))
        {
            $model->attributes=$_POST['ContactForm'];
            if($model->validate())
            {
                $headers="From: {$model->email}\r\nReply-To: {$model->email}";
                mail(Yii::app()->params['adminEmail'],$model->subject,$model->body,$headers);
                Yii::app()->user->setFlash('contact','Thank you for contacting us. We will respond to you as soon as possible.');
                $this->refresh();
            }
        }
        $this->render('contact',array('model'=>$model));
    }

    /**
     * Displays the login page
     */
    public function actionLogin()
    {
        $model=new LoginForm;

        // if it is ajax validation request
        if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')
        {
            echo CActiveForm::validate($model);
            Yii::app()->end();
        }

        // collect user input data
        if(isset($_POST['LoginForm']))
        {
            $model->attributes=$_POST['LoginForm'];
            // validate user input and redirect to the previous page if valid
            if($model->validate() && $model->login())
                $this->redirect(Yii::app()->user->returnUrl);
        }
        // display the login form
        $this->render('login',array('model'=>$model));
    }

    /**
     * Logs out the current user and redirect to homepage.
     */
    public function actionLogout()
    {
        Yii::app()->user->logout();
        $this->redirect(Yii::app()->homeUrl);
    }
}

ContactForm.php =这是模型。

<?php

/**
 * ContactForm class.
 * ContactForm is the data structure for keeping
 * contact form data. It is used by the 'contact' action of 'SiteController'.
 */
class ContactForm extends CFormModel
{
    public $name;
    public $email;
    public $subject;
    public $body;
    public $verifyCode;

    /**
     * Declares the validation rules.
     */
    public function rules()
    {
        return array(
            // name, email, subject and body are required
            array('name, email, subject, body', 'required'),
            // email has to be a valid email address
            array('email', 'email'),
            // verifyCode needs to be entered correctly
            array('verifyCode', 'captcha', 'allowEmpty'=>!CCaptcha::checkRequirements()),
        );
    }

    /**
     * Declares customized attribute labels.
     * If not declared here, an attribute would have a label that is
     * the same as its name with the first letter in upper case.
     */
    public function attributeLabels()
    {
        return array(
            'verifyCode'=>'Verification Code',
        );
    }
}

这是观点: contact.php

<?php
$this->pageTitle=Yii::app()->name . ' - Contact Us';
$this->breadcrumbs=array(
    'Contact',
);
?>

<h1>Contact Us</h1>

<?php if(Yii::app()->user->hasFlash('contact')): ?>

<div class="flash-success">
    <?php echo Yii::app()->user->getFlash('contact'); ?>
</div>

<?php else: ?>

<p>
If you have business inquiries or other questions, please fill out the following form to contact us. Thank you.
</p>

<div class="form">

<?php $form=$this->beginWidget('CActiveForm'); ?>

    <p class="note">Fields with <span class="required">*</span> are required.</p>

    <?php echo $form->errorSummary($model); ?>

    <div class="row">
        <?php echo $form->labelEx($model,'name'); ?>
        <?php echo $form->textField($model,'name'); ?>
    </div>

    <div class="row">
        <?php echo $form->labelEx($model,'email'); ?>
        <?php echo $form->textField($model,'email'); ?>
    </div>

    <div class="row">
        <?php echo $form->labelEx($model,'subject'); ?>
        <?php echo $form->textField($model,'subject',array('size'=>60,'maxlength'=>128)); ?>
    </div>

    <div class="row">
        <?php echo $form->labelEx($model,'body'); ?>
        <?php echo $form->textArea($model,'body',array('rows'=>6, 'cols'=>50)); ?>
    </div>

    <?php if(CCaptcha::checkRequirements()): ?>
    <div class="row">
        <?php echo $form->labelEx($model,'verifyCode'); ?>
        <div>
        <?php $this->widget('CCaptcha'); ?>
        <?php echo $form->textField($model,'verifyCode'); ?>
        </div>
        <div class="hint">Please enter the letters as they are shown in the image above.
        <br/>Letters are not case-sensitive.</div>
    </div>
    <?php endif; ?>

    <div class="row buttons">
        <?php echo CHtml::submitButton('Submit'); ?>
    </div>

<?php $this->endWidget(); ?>

</div><!-- form -->

<?php endif; ?>

转到页面:http://yoursite/index.php/contact/激活SiteController中的actionContact方法。它抓取发布的联系信息,将其放入模型中,然后呈现视图。

CodeIgniter允许您使用Form Helper构建表单,但我更喜欢自己编写HTML。

试试这个(未经测试)

<?php
$fields = array('name'=>array('type'=>'input',name='fname')
                'desciprtion'=>array('type'=>'textarea',name='desc')
               );
?>
<form name="myform" action="" method="post">
<?php

foreach($fields as $key=>$value)
{
   echo "<label>$key</label>";
   echo " <$key['type'] name=\"$key['name']\" id=\"$key['id']>\">
}
?>
