Yii2

Question

根据Core Validators指南，minSize和maxSize被描述为

the minimum/maximum number of bytes required for the uploaded file.

但是没有说明这些属性适用于多少个文件。

是每个文件还是所有文件的总大小？

Answer 1

在验证器代码中，它检查方法 validateValue() 中的大小，因此每个文件的大小为 min/max，而不是所有文件。

foreach ($files as $file) {
    $result = $this->validateValue($file);
...

错误示例：

[
    "The file \"git-flow cheatsheet.png\" is too big. Its size cannot exceed 819.2 KiB.",
    "The file \"IMG_20170531_134929.jpg\" is too big. Its size cannot exceed 819.2 KiB.",
    "The file \"Lenovo sound recorder icon.jpg\" is too small. Its size cannot be smaller than 409.6 KiB.",
    "The file \"memorable-linux-milestone_502911b05dc45.jpg\" is too small. Its size cannot be smaller than 409.6 KiB."
]

Yii2 - 文件验证器的 minSize 和 maxSize 适用于多少个文件？
