通過href鏈接獲取價值

Question

我正在嘗試從href鏈接獲取值，並在數據庫中使用if。 但是我無法獲得價值。

以下是我的按鈕代碼，

 <a class="btn btn-info" href="scheduleSetTime.php?id='. $id .'">' . 'Set Time' . '</a> 

scheduleSetTime.php

 <div class="container bs-docs-container"> <div class="panel panel-default"> <div class="panel-heading">Schedule Activity</div> <div class="panel-body"> <div id="formbox"> <form id="formTable"> <table class="table table-hover"> <thead> <tr> <th>Start Time</th> <th>End Time</th> <th>Monday</th> <th>Tuesday</th> <th>Wednesday</th> <th>Thursday</th> <th>Friday</th> <th>Saturday</th> <th>Sunday</th> <th></th> </tr> </thead> <tbody> <tr> <th> <input type="text" class="form-control" name="startTime" id="starttime" width="50px"> </th> <th> <input type="text" class="form-control" name="endTime" id="endtime"> </th> <th> <input type="checkbox" name="Monday" value="1" id="monday"> </th> <th> <input type="checkbox" name="Tuesday" value="1" id="tuesday"> </th> <th> <input type="checkbox" name="Wednesday" value="1" id="wednesday"> </th> <th> <input type="checkbox" name="Thursday" value="1" id="thursday"> </th> <th> <input type="checkbox" name="Friday" value="1" id="friday"> </th> <th> <input type="checkbox" name="Saturday" value="1" id="saturday"> </th> <th> <input type="checkbox" name="Sunday" value="1" id="sunday"> </th> <th> <input type="button" class="btn btn-success" value="Add" id="send"> </th> <th>Click the Add button to add to the list below</th> </tr> </tbody> </table> </form> </div> <table class="table table-hover"> <thead> <tr> <th>Start Time</th> <th>End Time</th> <th>Monday</th> <th>Tuesday</th> <th>Wednesday</th> <th>Thursday</th> <th>Friday</th> <th>Saturday</th> <th>Sunday</th> <th></th> <th></th> </tr> </thead> <tbody id="comment"> </tbody> </table> 

我用於scheduleSetTime.php的JavaScript，

 $(document).ready(function() { function showComment() { $.ajax({ type: "post", url: "registerarray.php", data: "action=showcomment", success: function(data) { $("#comment").html(data); } }); } showComment(); $("#send").click(function() { var starttime = $("#starttime").val(); var endtime = $("#endtime").val(); if (document.getElementById('monday').checked) { var monday = $("#monday").val(); } if (document.getElementById('tuesday').checked) { var tuesday = $("#tuesday").val(); } if (document.getElementById('wednesday').checked) { var wednesday = $("#wednesday").val(); } if (document.getElementById('thursday').checked) { var thursday = $("#thursday").val(); } if (document.getElementById('friday').checked) { var friday = $("#friday").val(); } if (document.getElementById('saturday').checked) { var saturday = $("#saturday").val(); } if (document.getElementById('sunday').checked) { var sunday = $("#sunday").val(); } var dataString = "starttime1=" + starttime + "&endtime1=" + endtime + "&monday1=" + monday + "&tuesday1=" + tuesday + "&wednesday1=" + wednesday + "&thursday1=" + thursday + "&friday1=" + friday + "&saturday1=" + saturday + "&sunday1=" + sunday + "&action=addcomment"; $.ajax({ type: "post", url: "registerarray.php", data: dataString, success: function(data) { showComment(); $("#formTable")[0].reset(); } }); return false; }); }); 

我的registerarray.php，

 <?php $action = $_POST["action"]; if ($action == "showcomment") { require_once 'dbfunction.php'; include_once 'checkLoginStatus.php'; $con = getDbConnect(); $schedule_Id = $_GET["id"]; $staff_Id = $staff_information["staff_Id"]; if (!mysqli_connect_errno($con)) { $show = "SELECT * FROM scheduletime WHERE schedule_Id = '$schedule_Id' AND staff_Id = '$staff_Id'"; $result = mysqli_query($con, $show); $html = ""; while ($row = mysqli_fetch_array($result)) { $r = "<tr>"; $r .= "<td>" . $row["startTime"] . "</td>"; $r .= "<td>" . $row["endTime"] . "</td>"; $r .= "<td>" . $row["Monday"] . "</td>"; $r .= "<td>" . $row["Tuesday"] . "</td>"; $r .= "<td>" . $row["Wednesday"] . "</td>"; $r .= "<td>" . $row["Thursday"] . "</td>"; $r .= "<td>" . $row["Friday"] . "</td>"; $r .= "<td>" . $row["Saturday"] . "</td>"; $r .= "<td>" . $row["Sunday"] . "</td>"; $r .= "<td></td>"; $r .= "</tr>"; $html .= $r; } header("Content-type: text/plain"); echo( $html); mysqli_close($con); } else { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } ?> <?php } else if ($action == "addcomment") { require_once 'dbfunction.php'; $con = getDbConnect(); $schedule_Id = $_GET["id"]; $starttime2 = $_POST['starttime1']; $endtime2 = $_POST['endtime1']; $monday2 = $_POST['monday1']; $tuesday2 = $_POST['tuesday1']; $wednesday2 = $_POST['wednesday1']; $thursday2 = $_POST['thursday1']; $friday2 = $_POST['friday1']; $saturday2 = $_POST['saturday1']; $sunday2 = $_POST['sunday1']; $staff_Id = $staff_information["staff_Id"]; if (mysqli_connect_errno($con)) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } else { $query = "INSERT INTO scheduletime (schedule_Id, staff_Id, startTime, endTime, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday)" . "VALUES ('$schedule_Id', '$staff_Id', '$starttime2', '$endtime2', '$monday2', '$tuesday2', '$wednesday2', '$thursday2', '$friday2', '$saturday2', '$sunday2')"; mysqli_query($con, $query); } echo "Your comment has been sent"; mysqli_close($con); } 

scheduleSetTime.php的視圖

在registerarray.php中，我使用了$ _GET [“ id”]; 獲取ID號，但沒有成功。 還有另一種獲取id值的方法嗎？

Answer 1

當用戶單擊您的按鈕之一時，GET變量id將發送到scheduleSetTime.php。 您嘗試在registerarray.php中檢索它。

一個解決方案是：

1. 在scheduleSetTime.php中以de id為值將隱藏的輸入元素添加到表單中。 例如：

    <input type="hidden" name="id" value="<?php echo htmlentities($_GET['id']); ?>" id="id"> 

2. 在POST請求中將此id值發送到registerarray.php。 在聲明dataString之后添加以下代碼dataString達到目的：

    dataString += "&id=" + $("#id").val(); 

3. 在registerarray.php中檢索id 。 由於id是作為POST變量發送的，因此應在registerarray.php中將$_GET['id']與$_POST['id'] 。

那應該解決您的問題！
