如何从表单数据获取数组

Question

我在我们的项目中正在使用Metronic Form Repeater。

我的表单标签没有任何加密或内容类型。

<form class="m-form" action="<?php echo $action; ?>" method='POST'></form>

提交表单时，我可以看到如下数据

不幸的是，当我打印$ _POST时，看到一个空数组。

表格代码

<div class="form-group  m-form__group row" id="m_repeater_1">
    <div data-repeater-list="" class="col-lg-12">
        <div data-repeater-item class="form-group m-form__group row align-items-center">
            <div class="col-md-3">
                <div class="m-form__group m-form__group--inline">
