Question

我正在尝试将某些日历数据更新到数据库。但每次我更新时都会更新我的天专栏，会更新18<span class="label label-danger" xss=removed>Notice</span>它应该只更新数字 18

的日期列

我不确定为什么$this->input->post('day')添加了跨度信息。

这是我的var转储。

array (size=2)
  17 => string 'Event 17-12-15' (length=14)
  '18<span class="label label-danger" xss=removed>Notice</span>' => string '26' (length=2)

问题：


如何仅使用数字而不是使用span更新日期列？

可能导致其更新数字的范围是什么？

尝试：

$this->input->post('day', TRUE)

$this->input->post('day', FALSE)

控制器

注意：我在控制器上使用模型功能只是为了测试

<?php

    public function __construct() {

            $year = date('Y');
        } else {
            $year = $this->uri->segment(3);
        }

        $data['year'] = $year;

        if ($this->uri->segment(4) == FALSE) {
            $month = date('m');
        } else {
            $month = $this->uri->segment(4);

为什么遇到这个问题可能有几种选择。通过检查传递给您的控制器day_num来确定哪一个开始？这样做：

<script type="text/javascript">
$(document).ready(function() {

    $('.calendar .day').click(function() {

        day_num  = $(this).find('.day_num').html();
        day_data = prompt('Enter Event', $(this).find('.content').html());

        if (day_data != null) {
            $.ajax({
                url: window.location,
                type: 'POST',
                data: {
                    day: day_num,
                    data: day_data
                },
                success: function(msg) {
                    //location.reload(); turn off the reload for now.
                    alert(day_num); //what does this alert show?
                }
            });
        }
    });
});
