javascript - PHP 联系表单中的多个字段

标签 javascript php jquery form-fields

我正在创建一个表单，根据需要动态添加其他字段。

如何在 PHP 联系表单中注册这些动态字段？

另外，为什么删除按钮会导致 Bootstrap 核心 jQuery 出错？

JavaScript:

    $(document).ready(function () {
        $('#btnAdd').click(function () {
            var num = $('.clonedInput').length; // how many "duplicatable" input fields we currently have
            var newNum = new Number(num + 1);      // the numeric ID of the new input field being added

            // create the new element via clone(), and manipulate it's ID using newNum value
            var newElem = $('#input' + num).clone().attr('id', 'input' + newNum);

            //Take one from value of hidden field

最佳答案

您的 $_POST 变量中将包含新字段，并且您可以使用 $_POST['child4'] 访问每个字段(不要让您的仅像您一样输入名称数字)。你现在可能会想出一个像这样的循环

foreach($_POST as $key => $value) {
    if (strpos($key, 'child') === 0) {
        // value starts with book_
    }
}
