Hello guys, it’s been a long time since my last post.
Today I come to ask for help with an ajax function.
This is the full picture:
I got a form in a bootstrap modal and within the form there are 3 dropdowns and 4 textfields. Alumno and Asignatura are dependent dropdowns. That’s working fine. The problem is I need to populate the textfields below. Nota1, Nota2, Nota3 and Nota4 when I select Asignatura.
Here’s some code:
Model class Nota.php
class Nota extends \yii\db\ActiveRecord
{
/**
* {@inheritdoc}
*/
public static function tableName()
{
return 'nota';
}
/**
* {@inheritdoc}
*/
public function rules()
{
return [
[['id_alumno', 'id_asignatura', 'id_curso'], 'required'],
[['id_alumno', 'id_asignatura'], 'integer'],
[['nota1', 'nota2', 'nota3', 'nota4', 'promedio'], 'number'],
[['id_curso'], 'string', 'max' => 45],
[['id_alumno'], 'exist', 'skipOnError' => true, 'targetClass' => Alumno::className(), 'targetAttribute' => ['id_alumno' => 'id']],
[['id_asignatura'], 'exist', 'skipOnError' => true, 'targetClass' => Asignatura::className(), 'targetAttribute' => ['id_asignatura' => 'id']],
[['id_curso'], 'exist', 'skipOnError' => true, 'targetClass' => Curso::className(), 'targetAttribute' => ['id_curso' => 'id']],
];
}
/**
* {@inheritdoc}
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'id_alumno' => 'Alumno',
'id_asignatura' => 'Asignatura',
'id_curso' => 'Curso',
'nota1' => 'Nota1',
'nota2' => 'Nota2',
'nota3' => 'Nota3',
'nota4' => 'Nota4',
'promedio' => 'Promedio',
];
}
/**
* @return \yii\db\ActiveQuery
*/
public function getAlumno()
{
return $this->hasOne(Alumno::className(), ['id' => 'id_alumno']);
}
/**
* @return \yii\db\ActiveQuery
*/
public function getAsignatura()
{
return $this->hasOne(Asignatura::className(), ['id' => 'id_asignatura']);
}
/**
* @return \yii\db\ActiveQuery
*/
public function getCurso()
{
return $this->hasOne(Curso::className(), ['id' => 'id_curso']);
}
}function actionListarNota in NotaController.php
public function actionListarNotas($id_alumno, $id_asignatura)
{
//Almacena todas las notas donde 'id_alumno' = $id_alumno y 'id_asignatura' = $id_asignatura
$notas = Nota::find()
->select(['nota1', 'nota2', 'nota3', 'nota4'])
->where(['id_alumno' => $id_alumno])
->andWhere(['id_asignatura' => $id_asignatura])
->all();
foreach ($notas as $nota){
echo Json::encode($nota);
}
}_form.php view of Nota
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use yii\helpers\ArrayHelper;
/* @var $this yii\web\View */
/* @var $model app\models\Nota */
/* @var $form yii\widgets\ActiveForm */
?>
<div class="nota-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'id_curso')->dropDownList(
ArrayHelper::map(app\models\Curso::find()->all(),'id', 'id'),
[
'prompt' => 'Seleccione un curso',
'onchange' => '$.post("index.php?r=alumno/listar-alumnos&id=' . '"+$(this).val(), function(data){
$("#nota-id_alumno").html(data);
});',
]); ?>
<?= $form->field($model, 'id_alumno')->dropDownList(
ArrayHelper::map(app\models\Alumno::find()->all(),'id', 'nombre'),
[
'prompt' => 'Seleccione un alumno',
]); ?>
<?= $form->field($model, 'id_asignatura')->dropDownList(
ArrayHelper::map(app\models\Asignatura::find()->all(),'id', 'nombre'),
[
'prompt' => 'Seleccione una asignatura',
'onchange' => '$.get("index.php?r=nota/listar-notas&id_alumno=' . '"+$("#nota-id_alumno").val()' .
'+"&id_asignatura=' . '"+$(this).val(), function(data){
alert(data);
$("#nota-nota1").attr("value", data);
});'
]); ?>
<?= $form->field($model, 'nota1')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'nota2')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'nota3')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'nota4')->textInput(['maxlength' => true]) ?>
<div class="form-group">
<?= Html::submitButton('Guardar', ['class' => 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>Here’s a picture of the form and the network response. I need to populate all textfields with data I fetch from actionListarNotas. Im getting all data in the first textfield instead. Im new to ajax. Any suggestions??
Thanks in advance.
