Update textInput Value from DropDownList

Please I got a problem on Yii2:

I want to insert value into a textInput field based on changes in the selected option from a dropdownlist. Here is my code:

<?= $form->field($model, 'course_taken')->dropDownList(ArrayHelper::map(Courses::find()->all(),'course_code','course_code')) ?>


<?= $form->field($model, 'course_details')->textInput(['maxlength' => true]) ?>

So when the user selects a course from the dropdownlist, the textInput will display the course details of the selected row. Both course_taken and course_details are columns from the same database table.

Thanks in advance.

please try this link

Thanks.

But that did not work. My case is slightly different. Any more help, please?

Hi foxychev

Try this,

<?= $form->field($model, 'course_taken')->dropDownList(

    ArrayHelper::map(Courses::find()->all(),'course_code','course_code'), 

    [

        'prompt'=>'--Select--',

        'onchange'=>'$("#model-course_details").val($("#model-course_taken option:selected").text());'

    ])

?>

<?= $form->field($model, 'course_details')->textInput(['maxlength' => true]) ?>

Tried it but nothing happened. The course_details textinput remained blank after making selection…

<?= $form->field($model, 'course_taken')->dropDownList(

    ArrayHelper::map(Courses::find()->all(),'course_code','course_code'), 

    [

        'prompt'=>'--Select--',

        'onchange'=>'$("#course_details").val($("#course_taken option:selected").text());',

        'id'=>'course_taken',

    ])

?>

<?= $form->field($model, 'course_details')->textInput(['maxlength' => true, 'id'=>'course_details']) ?>

Set the field ID’s manually and check it.

Did that work? I’m in the same situation… I’ll try what Selvakumar suggests…

My case is kind of different how ever I tried this option to see the behavior and It didn’t work. I coded this:

<?=$form->field($ordenProducto, 'id_producto')->dropDownList(ArrayHelper::map($catProductos,'id','descripcion'),

             ['prompt'=>'-Choose a option-',

              'onchange'=>'if($(this).val() == 1){

                 $("#precio_unitario").val("333"); }'

              ]); ?>

    <?= $form->field($catProductos, 'precio_unitario')->textInput(['maxlength' => true, 'id'=>'#precio_unitario']) ?>

Is there something wrong?
