yii2 select2 by kartik-v 设置默认值 [英] yii2 select2 by kartik-v set default value

问题描述

我有一个关于 yii2 kartik-v widget select 2 的问题.

I've a question about yii2 kartik-v widget select 2.

小部件附加到我视图中的一个字段

the widget is attached to a field in my view

<?=
$form->field($model, 'address')->widget(Select2::className(), [
    'options' => ['placeholder' => 'Inserta an address '],
    'pluginOptions' => [
        'allowClear' => true,
        'minimumInputLength' => 3,
        'ajax' => [
            'url' => Url::to(['register/addresses']),
            'dataType' => 'json',
            'data' => new JsExpression('function(params) { return {q:params.term}; }')
        ],
        'escapeMarkup' => new JsExpression('function (markup) { return markup; }'),
        'templateResult' => new JsExpression('function(address) { return address.name; }'),
        'templateSelection' => new JsExpression('function (address) { return address.name; }'),
    ],
    'pluginEvents' => [
        "select2:select" => "function(e) {
                      // some function

                }",
    ],
]);
?>

如果在我的控制器中我想为此字段设置一个值

if in my controller i want to set to this field a value

like: $model->address = "Some Value"; 在视图中字段保持空白

like: $model->address = "Some Value"; on the view the field remain blank

我能做什么?

更新！

正如文档所说，如果我使用此插件的 ajax 版本，我可以使用选项:'initValueText'.所以我试图设置 'initValueText' =>$model->address, 但结果是一样的

As the documentation say i can use the option: 'initValueText' if i use the ajax version of this plugin. So i've tried to set 'initValueText' => $model->address, but the result is the same

推荐答案

嘿，我遇到了与 #ajax 相同的问题，既没有显示占位符，也没有显示 initValueText我做的是这个

hey i had the same issue with #ajax neither placeholder nor initValueText were showing what i did was this

<?php
    $product = $model->product_id ? Product::findOne($model->product_id)->name : 'select ....';
    echo $form->field($model, 'product_id')->widget(Select2::classname(), [
        'initValueText' => $product, // set the initial display text
        // 'options' => ['placeholder' => 'select ....'],
        'pluginOptions' => [
            'allowClear' => true,
            'minimumInputLength' => 3,
            'ajax' => [
                'url' => Url::to(['list']),
                'dataType' => 'json',
                'data' => new JsExpression('function(params) { return {q:params.term}; }')
            ],
            'escapeMarkup' => new JsExpression('function (markup) { return markup; }'),
            'templateResult' => new JsExpression('function(product_id) { return product_id.name; }'),
            'templateSelection' => new JsExpression('function (product_id) { return product_id.name; }'),
        ],
    ]);?>

如果型号是新的，则显示select ...."，否则显示产品名称因为选项"也没有做太多希望这对某人有希望

if the model is new 'select ....' is shown else the product's name since "options" is not doing much either hope this will be hopeful to someone
