【中文标题】如何使用php将上一页可点击的url保存在数据库中？【英文标题】：how to save previous page clikable url in database using php? 【发布时间】：2017-03-24 06:55:52 【问题描述】：我在项目中有以下 div。点击“request for demo”按钮后，它将重定向到下一个窗口到注册表（链接在javascript函数中提到）。单击按钮并保存注册后，我想将相关的 div id 保存在数据库中。
以下是我的 html 和 javascript
<div class="row">
<div class="col-md-4 col-sm-6 pos-vertical">
<span><b>Supermarkets, Fruits & Vegetables</b></span>
<hr>

</div>
<div class="col-md-4 col-sm-6 pos-vertical">

</div>
<div class="col-md-4 col-sm-6 pos-vertical">

<button type="button" onclick="openWin()" class="modalBtn btn btn-default" id="Fashion Jewellery Shop" >Request for Demo</button>
</div>
</div>
在每个 div 按钮上调用以下函数，
<script>
function openWin()
window.open("register.php");
</script>
点击每个 div 按钮后，表单将在新窗口中打开，
<div class="register">
<div class="container">
<div class="row main">
<div class="main-register main-center">
<form class="" method="post" id="contact-form">
<div class="form-group">
<div class="cols-sm-10">
<div class="input-group">
<span class="input-group-addon" id="register-icon"><i class="fa fa-user fa" aria-hidden="true"></i></span>
<input type="text" class="form-control" id="name" placeholder="Enter your Name"/>
</div>
</div>
</div>
<div class="form-group">
<div class="cols-sm-10">
<div class="input-group">
<span class="input-group-addon" id="register-icon"><i class="fa fa-envelope fa" aria-hidden="true"></i></span>
<input type="text" class="form-control" id="email" placeholder="Enter your Email"/>
</div>
</div>
</div>
<div class="form-group">
<div class="cols-sm-10">
<div class="input-group">
<span class="input-group-addon" id="register-icon"><i class="fa fa-phone fa" aria-hidden="true"></i></span>
<input type="text" class="form-control" id="contact_no" placeholder="Enter your contact number"/>
</div>
</div>
</div>
<input type="hidden" id="requestType">
<div class="form-group ">
<button class="btn btn-primary btn-lg btn-block register-button submit">Register</a>
</div>
</form>
<span class="success" style="display:none">Thank You for Register with us.</span>
</div>
</div>
</div>
</div>
表单将使用 ajax 和 php 保存
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"></script>
<script type="text/javascript" >
$(function()
$(".modalBtn").click(function()
var formName = $(this).attr("id");
$('#requestType').val(formName);
$('.success').hide();
$('.error').hide();
$('#contact-form').show();
$("#demoModal").modal();
);
$(".submit").click(function()
var name = $("#name").val();
var requestType = $('#requestType').val();
var contact_no = $("#contact_no").val();
var email = $("#email").val();
//alert(requestType);
var dataString = 'name='+ name + '&contact_no=' + contact_no + '&email=' + email+ '&requestType=' + requestType;
if(name=='' || contact_no=='' || email=='')
$('.success').fadeOut(200).hide();
$('.error').show();
else
$.ajax(
type: "POST",
url: "register.php",
data: dataString,
success: function()
$('.success').fadeIn(200).show();
$('.error').fadeOut(200).hide();
$('#contact-form').hide();
);
return false;
);
);
</script>
插入数据的php代码是，
<?php
require('connection.php');
if($_POST)
$id = $_POST['regid'];
$name = $_POST['name'];
$contact_no = $_POST['contact_no'];
$email = $_POST['email'];
$requestType = $_POST['requestType'];
if ($id == '')
$sql = "INSERT INTO registration(name,contact_no,email,requestType) VALUES ".
"('".$name."', '".$contact_no."', '".$email."','".$requestType."')";
$query_result = mysql_query( $sql );
if(!$query_result )
echo 'Could not enter data: ' . mysql_error();
else
//header("Location: lead-view.php?s=Y");
$successMsg = 'Record instered successfully';
?>
我想在提交相关潜水点击按钮的表单后将这些 div id 保存为 url。 url 将保存在数据库的“requestType”字段中。请帮忙。
【问题讨论】：
【参考方案1】：您可以使用 sessionStorage 来传递 requestType 值。 https://www.nczonline.net/blog/2009/07/21/introduction-to-sessionstorage/
在调用 openWin() 时，将 div 值传递给它。例如：
<button type="button" onclick="openWin('abc')" class="modalBtn btn btn-default" id="Supermarkets, Fruits and Vegetables" >Request for Demo</button>
然后将这个值保存在sessionStorage中，如下：
function openWin(div_value)
sessionStorage.setItem("registerType", div_value);
window.open("register.php");
您可以在 register.php 中检索此变量：
var registerType = sessionStorage.getItem("registerType");
将此值添加到注册表中的隐藏输入控件并保存到数据库。
<input type="hidden" id="requestType">
【讨论】：
但是表单会保存 register.php 点击每个 div 按钮后，相同的 register.php 表单将在新窗口中打开并保存在数据库中以上是关于如何使用php将上一页可点击的url保存在数据库中？的主要内容，如果未能解决你的问题，请参考以下文章
