Question

我想将uploadFile添加到：https://github.com/thyseus/yii2-message

我在模型中的Message.php添加了public function rules() { return [ [['title'], 'required'], [['file2'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg'], [['title', 'message', 'context'], 'string'], [['title'], 'string', 'max' => 255], [['to'], IgnoreListValidator::class], [['to'], 'exist', 'targetClass' => Yii::$app->getModule('message')->userModelClass, 'targetAttribute' => 'id', 'message' => Yii::t('app', 'Recipient has not been found'), ], [['to'], 'required', 'when' => function ($model) { return $model->status != Message::STATUS_SIGNATURE && $model->status != Message::STATUS_DRAFT; }], ]; }

这是我在模型中的规则：

    <?= $form->field($model, 'message')->textarea(['rows' => 6]) ?>
    <?php
    echo $form->field($model, 'file2')->widget(FileInput::classname(), [
        'options' => ['accept' => 'image/*'],
    ]);

// With model & without ActiveForm
        echo '<label class="control-label">Add Attachments</label>';
        echo FileInput::widget([
            'model' => $model,
            'attribute' => 'file2',
            'options' => ['multiple' => true]
        ]);
        ?>

这是我的观点：

  $model = new Message();
    $model->attributes = $attributes;
    var_dump($attributes);
    die;

这是我的sendMessage函数

array(4) { ["to"]=> array(1) { [0]=> string(2) "65" } ["title"]=> string(3) "asd" ["message"]=> string(30) "asd  . " ["file2"]=> string(0) "" }

为什么上传文件后我的结果是这个？

var gulp        = require('gulp');
var browserSync = require('browser-sync').create();
var sass        = require('gulp-sass');


gulp.task('serve', ['sass'], function() {

    browserSync.init({
        proxy:"dummy.com"
    });

    gulp.watch("craft/web/sass/*.scss", ['sass']);
    gulp.watch("craft/templates/*.html").on('change', browserSync.reload);
});

gulp.task('sass', function() {
    return gulp.src("craft/web/sass/*.scss")
        .pipe(sass().on('error', sass.logError))
        .pipe(gulp.dest("craft/web/css"))
        .pipe(browserSync.stream());
});

gulp.task('default', ['serve']);

file2为空！

设置表单时，需要提及multipart / form-data。请查看以下示例。
