How to upload multiple images in one post?

Question

Yii

Here is the form. She is simple. I just need to upload all the images to the uploads root folder and so that their address remains in the database:

<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]) ?>

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

    <?= $form->field($model, 'text')->textarea(['rows' => 6]) ?>

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

    <?= $form->field($model, 'status')->dropDownList(['Черновик','Публикация']) ?>

    <?= $form->field($model, 'sort')->textInput() ?>

    <?= $form->field($model, 'date_added')->textInput() ?>

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

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

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

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

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

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

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

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

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

    <div class="form-group">
        <?= Html::submitButton('Save', ['class' => 'btn btn-success']) ?>
    </div>

    <?php ActiveForm::end(); ?>

Answer 1

Everything is in the docks: https://www.yiiframework.com/doc/guide/2.0/en/inpu...
YouTube has a lot of videos on uploading files to youtube
Yes, and everything is the same in essence as with one, sometimes there are nuances in the form:
UploadedFile::getInstancesinstead of UploadedFile::getInstancethe second method will return an object, the first array of objects. But in your form, all files have separate attributes, and not in one, so this will not affect you.

Answer 2

field($model, 'eag_img[]')
