¿Cuál es la diferencia entre formulario y chtml en yii?

confusión entre formulario y chtml

Solía ​​​​formar para escribir formulario y enviar a la base de datos que funcionaba bien, pero para algunos lugares particulares, según la búsqueda de Google, usé CHTML en lugar de formulario. pero cuando envié ese formulario a la base de datos

El valor del campo de texto CHTML no se envía a la base de datos

aquí va mi código

_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>

por qué estas personas me votaron negativamente, escribí mi problema real, soy nuevo en yii, si tu experto es como un experto, no hagas tonterías -

1 Respuestas

Echa un vistazo aquí Crear formulario. Desde Yii 1.1.1 hay un widget llamado CActiveForm así que cuando usas este widget, creas las entradas del formulario con $form->textField($model,'username')En lugar de usar CHtml::activeTextField($model,'username')pero ambos funcionan de la misma manera.

Entonces, si ese campo no se guarda en la base de datos, probablemente se deba a que no lo ha agregado a las reglas de su modelo.

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

¿Qué quieres que compruebe? - Puigcerber

Usé chtml para la lista desplegable; ese valor no se envía a la base de datos. Devendar

¿Has añadido las reglas al modelo? ¿Estás guardando el modelo en el controlador? - Puigcerber

lo siento amigo, estoy agregando el código completo del controlador y Ver - 1 min - Devendar

¿Cuál es el campo que no se guarda? - Puigcerber
