Passing value to textarea. Is it possible?

[rossaddison]

I have the following code in view\invoice\inv\mailer_invoice.php:

<?= Field::text($form, 'body')->addInputAttributes(['id'=>'mailerinvform-body'])
                                                  ->addInputAttributes(['rows'=>20]) 
                                                  ->addInputAttributes(['class'=>'email-template-body form-control taggable'])
                                                  ->addInputAttributes(['value' =>$auto_template['body'] ?? ''])
                                                  ->hideLabel()
                    ?>

I would like to pass an email template to a textarea. But textareas by default do not accept a value attribute whereas textboxes do as illustrated in the code above. The above code works for a textbox but as expected there is limited space to work in with the text box. Is it possible to pass value to a textarea in Yii?

@terabytesoftw could you take a look?

I am using a jquery script at the bottom of mailer_invoice.php to receive the default email template under settings ie. 'Normal', from the invcontroller via $auto_template['body'] as follows:

mailer_invoice.php
<?= Field::textarea($form, 'body')->addInputAttributes(['id'=>'mailerinvform-body'])
                                                  ->addInputAttributes(['class'=>'email-template-body form-control taggable'])
                                                  ->addInputAttributes(['style' => 'height: 300px'])
                                                  ->maxlength(1500)
                                                  ->rows(120)
                                                  ->wrap('hard')
                                                  ->hideLabel()
?>

<?=
$js6 = "$(document).ready(function() {".
        'var textContent = '.$auto_template['body'].';'.
        '$("#mailerinvform-body").val(textContent);'.
        '});';
    echo Html::script($js6)->type('module');
    // Dump script with 'echo $js6' for testing
?>

The email template then changes with the following code if they select an item in the email template dropdown box.

"$(document).ready(function ()  {".
       'var new_key = "";'.
       'var new_val = "";'.
       'var template_fields = ["body", "subject", "from_name", "from_email", "cc", "bcc", "pdf_template"];'.
       "$('#mailerinvform-email_template').change(function () {".     
            'var email_template_id = $(this).val();'.
            "if (email_template_id === '') return;".     
            
            "var url =  $(location).attr('origin') + ".'"/invoice/emailtemplate/get_content/"'.'+ email_template_id;'.
            "$.ajax({ type: 'GET',".
                'contentType: "application/json; charset=utf-8",'.
                'data: {'.
                        'email_template_id: email_template_id'.
                '},'.
                'url: url,'.
                'cache: false,'.
                "dataType: 'json',".
                'success: function (data) {'.
                    'var response = parsedata(data);'.
                    'if (response.success === 1) {'.
                        'for (var key in response.email_template) {'.
                            'if (response.email_template.hasOwnProperty(key)) {'.
                                'new_key = key.replace("email_template_", "");'.
                                'new_val = response.email_template[key];'. 
                                'switch(new_key) {'.
                                    'case "subject":'.
                                        '$("#mailerinvform-subject.email-template-subject.form-control").val(new_val);'.
                                    'break;'.
                                    'case "body":'.                                        
                                        '$("textarea#mailerinvform-body.email-template-body.form-control.taggable").val(new_val);'.
                                    'break;'.                                   
                                    'case "from_name":'.

                                    'break;'.
                                    'case "from_email":'.                                    
                                        '$("#mailerinvform-from_email.email-template-from-email.form-control").val(new_val);'.
                                    'break;'.
                                    'case "cc":'.            
                                        '$("#mailerinvform-cc.email-template-cc.form-control").val(new_val);'.
                                    'break;'.                                    
                                    'case "bcc":'.            
                                        '$("#mailerinvform-bcc.email-template-bcc.form-control").val(new_val);'.
                                    'break;'.
                                    'case "pdf_template":'.
                                        '$("#mailerinvform-pdf_template.email-template-pdf-template.form-control").val(new_val).trigger('."'change');".
                                    'break;'.    
                                    'default:'.
                                '}'.                                                               
                            '}'.
                        '}'.  
                    '}'.
                '}'.
            '});'.
        '});'. 
    '});'.

No value is passed to the textarea by means of addInputAttributes('value' ... as can be done by means of the Field::text.

The above code is working but if there is a simpler way other than using javascript I will apply it.

I have looked into your suggestion but will stick with my solution for the time being. Thank you for your help.

@rossaddison according to https://github.com/yiisoft/form/blob/d2333f9a0a77f6dcb00db1ab8ee95ec4426ea133/src/Field/Text.php#L247 you need to set the object property value and it should work
