чем разница между формой и CHTML в YII

Question

путаницы между формой и CHTML

я использовал для образования, чтобы написать форму анса представить в базу данных работает нормально, но для некоторых конкретных мест, в соответствии с поиском Google используется CHtml вместо форма. но когда я представил эту форму в базу данных

CHTML значение TextField не подает в базу данных

здесь идет мой код

_form.php

<script language="javascript"> 

function firstlang(flang,slang,tlang,math,scien,soci) 
{ 

var sflang=parseInt(flang)+parseInt(slang)+parseInt(tlang)+parseInt(math)+parseInt(scien)+parseInt(soci); 
document.getElementById('totalmarks').value=sflang; 
if(sflang>=300 && sflang<400) 
{ 
var flang='C'; 
document.getElementById('grade').value=flang; 
} 
else if(sflang>=400 && sflang<500) 
{ 
var flang='B'; 
document.getElementById('grade').value=flang; 
} 
else if(sflang>=550 && sflang<=600) 
{ 
var flang='A'; 
document.getElementById('grade').value=flang; 
} 
} 

</script>

Answer 1

Посмотрите здесь Creating Form. Так как Yii 1.1.1 есть виджет CActiveForm , то при использовании этого виджета вы создаете входы формы с $form->textField($model,'username') вместо CHtml::activeTextField($model,'username'), но оба работают одинаково.

Так что если это поле не сохраняется в базе данных, это, вероятно, потому, что вы не добавили его в правила своей модели.

public function rules() { 
    return array(
     array('username', 'safe'), 
    ); 
)
