Question

第二次发布此问题。希望我会得到一些必要的答案。

好吧，我是PHP的新手。我知道这是一个天真的问题，但我面临两个问题。

1）我应该根据所选的选项值显示div中字段'display_duration'的数据（选择框选项是从表中的字段'priority'获取的）。当用户点击声明选择选项“高”时，持续时间（3-4周）应显示在Div。

中

我的第二个问题是计算调度和到达日期，并在单独的div标签中显示结果。格式应为'01-Jan-2017'(dd-MMM-yyyy)。

arrival date = current date+arrival_interval_days(a field given in table);

同样适用于发货日期的计算。到达和发送日期计算也基于所选的优先级选项。

感谢您的帮助。

Answer 1

jquery应该有变化

$("#priority_duration").text(employeeData.display_duration);

此行应替换为

 $("#priority_duration").html(employeeData.display_duration);

您要返回true或false以获取下拉选项，因此只有response data而不是equals to(==)才能获得(!== 0) public function checkduration($priority_id){ $result = $this->db->query("SELECT priority_id, display_duration FROM tblpriority WHERE priority_id='".$priority_id."'"); $is_priority = $result->fetchAll(); if(count($is_priority)!== 0){ //return true; //Here instead of return true you need to pass the data what you get in response return $is_priority; } else{ return false; } }如果我错了，请检查并告诉我。

第二个答案。

如果您正在计算表格中给出的current_date + interval的到达日期，那么如果您没有更新间隔，则每天都会更改日期。它将永远延伸到下一个日期。在表格中给定持续时间的间隔

Answer 2

首先在order.php类中更改函数

public function checkduration($priority_id)
    {
        $result       = $this->db->query("SELECT priority_id, display_duration,dispatch_interval_days,arrival_interval_days FROM tblpriority WHERE priority_id='" . $priority_id . "'");
        $priorityData = $result->fetchAll();

        return $priorityData;
    }

而且，在ajax call（）中，php文件应如下所示。

<?php

use Cosmo\ConfigSettings;
use Cosmo\DAL\Order;

//End
//Application/DB Configuration
$config   = ConfigSettings::getInstance();
$basePath = $config->getBasePath();
//End

$response = [];

if (!empty($_REQUEST["priority_id"])) {
    print_r($_REQUEST);
    print_r($_REQUEST);
    $priority_id                        = $_REQUEST['priority_id'];
    $addUser                            = new Order();
    $priorityData                       = $addUser->checkduration($priority_id);
    $response['display_duration']       = '';
    $response['dispatch_interval_days'] = '';
    $response['arrival_interval_days']  = '';
    if (!empty($priorityData)) {
        $response['display_duration']       = $priorityData[0]['display_duration'];
        $response['dispatch_interval_date'] = date('j-M-Y', strtotime("+{$priorityData[0][dispatch_interval_days]} days"), time());
        $response['arrival_interval_date']  = date('j-M-Y', strtotime("+{$priorityData[0][arrival_interval_days]} days"), time());
    }
}
header('Content-Type: application/json');
echo json_encode($response);
exit;

现在，您可以在客户端显示所有数据，并以格式（201-Jan-2018）计算到达和发送日期

并且还为到达和派遣添加了2个div，并按优先级填充了ajax响应值。

<?php
use Cosmo\ConfigSettings;
use Cosmo\DAL\Order;

//End
//Application/DB Configuration
$config = ConfigSettings::getInstance();




$priority_list_data = new Order();
$priority_data = $priority_list_data->getPriorityList();
$priority_option = '<option value=""></option>';
if ($priority_data != false) {
    for ($i = 0; $i < count($priority_data); $i++) {
        $priority_option .= '<option value= "' . $priority_data[$i]['priority_id'] . '" >' . $priority_data[$i]['priority'] . '</option>';
    }
}
?>


<div class="panel-body">
    <span class="pull-left">Priority:</span>
    <select class="form-control" id="priority_selected">>
        <?php echo $priority_option; ?>
    </select>
    <div class="small" id="priority_duration" ></div>

    <div class="small" id="arrival_date" ></div>
    <div class="small" id="dispatch_date" ></div>
</div>

<script type="text/javascript" src="/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
    $(document).ready(function(){
        // code to get all records from table via select box
        $("#priority_selected").change(function() {
            var id = $(this).find(":selected").val();
            var dataString = 'priority_id='+ id;
            $.ajax({
                url: '_getEmployee.php',
                dataType: "json",
                data: dataString,
                cache: false,
                success: function(employeeData) {
                    if(employeeData) {
                        $("#priority_duration").html(employeeData.display_duration);
                        $("#arrival_date").html(employeeData.arrival_interval_date);
                        $("#dispatch_date").html(employeeData.dispatch_interval_date);

                    } else {

                        $("#priority_duration").hide();

                    }
                }
            });
        })
    });


</script>
