存储使用JavaScript数组饼干（或使用饼干作为一个数组） [英] storing cookies in an array with javascript(or using cookie as an array)
问题描述
编辑：
我用PHP解决它在某种程度上。它的那么具体，但我想如果有人需要它来分享。首先，我没有给任何具体名称的product_id的Cookie，但我只给如下所示
的onclick = \\的setcookie（'，$ FTC2。'，'到期'$ FTC2。'）;
所以每当用户点击任何产品，一个新的cookie是使用类似名称的product_id的名称创建= 2或名称= 32什么的。
然后我创建图表页面上一个foreach如下
＆LT; PHP的foreach（$ _ COOKIE为$饼干）{$回声饼干; ？}＆GT;
现在里显示所有存储的cookie值（在我的情况下，产品ID），现在我可以操纵它，因为我想和显示这是添加到也许图表它是如此简单，如此普遍的所有产品，但不知何故，我无法找到它了从早晨=））我希望这样可以节省别人的时间。
问题是：
我建立一个网上商店和我想要做的就是在显示页面showChart点击的所有产品。（一个很简单的网页，其中显示您通过点击chart_icon添加到您的图表中的产品）。我已经尝试了一些常见的几种方法，但我不能管理以某种方式做到这一点。我最后绝望的尝试是建立这个addToChart（）函数。
由于设置cookie部分作品好，我简化了code和粘贴刚才的重要组成部分（在我看来）。任何形式的帮助或建议将是AP preciated。我不希望任何人写的code我。
在此先感谢
为（$ I = 0; $ I＆LT; $ NUM; $ I ++）

JAVASCRIPT code从这里开始的。

VAR到期=新的日期（today.getTime（）+ 365 * 24 * 60 * 60 * 1000）;
函数getCookieVal（偏移）{
变种endstr = document.cookie.indexOf（;，偏移量）;
如果（endstr == -1）{endstr = document.cookie.length; }
返回UNESCAPE（document.cookie.substring（偏移，endstr））;
} 函数的getCookie（名称）{
VAR ARG =名称+=;
VAR阿伦= arg.length;
VAR CLEN = document.cookie.length;
变种I = 0;
而（I＆LT; CLEN）{
变种J = +阿伦;
如果（document.cookie.substring（I，J）== ARG）{
返回getCookieVal（J）;
}
I = document.cookie.indexOf（，I）+ 1;
如果（我== 0）打破;
}
返回null;
} 函数的setcookie（名称，值，过期，路径，域，安全）{ 的document.cookie =名称+=+越狱（值）+
（（过期）;到期=+到期：）+
（（路径）;路径=+路径：）+
（（域）;域=+域名：）+
（（安全）安全：）; } 的document.getElementById（饼干）.onclick =功能addToChart（）
{
VAR cookieValue =的document.getElementById（饼干）.value的;
VAR cookiearray =新的Array（）;
cookiearray = cookieValue.split（，）;
返回cookiearray; }
好吧，我已经解决了我用PHP的问题。它的那么具体，但我想如果有人需要它，分享它。
首先我没有给任何具体名称的product_id的Cookie，但我只给如下所示
的是点击PRODUCT_ID$ FTC2的变量， 的onclick = \\的setcookie（'，$ FTC2。'，'到期'$ FTC2。'）;
所以每当用户点击任何产品，一个新的cookie是使用类似名称的product_id的名称创建= 2或名称= 32什么的。
然后我创建图表页面上一个foreach如下
＆LT; PHP
的foreach（$ _ COOKIE为$饼干）
{
回声$饼干;
}？＆GT;
现在里显示所有存储的cookie值（在我的情况下，产品ID），现在我可以操纵它，因为我想和显示将被添加到图表的所有产品
也许它是那么容易，因此常见的，但不知何故，我无法找到它了，因为早上=））
Edit: I solved it somehow with PHP. Its so specific but I want to share it in case somebody needs it. First of all I didnt give any specific name as product_id for the cookie but I just give the variable of the product_id "$ftc2" which is clicked, shown as below
onclick=\"SetCookie('".$ftc2."', '".$ftc2."', 'expiry');
So whenever user clicks on any product, a new cookie is created with the name of the product_id like name=2 or name=32 whatever.
then I have created a foreach on the chart page as below
<?php foreach($_COOKIE as $cookies) { echo $cookies; } ?>
It displayes now all stored cookie values(in my case product ids) and now I can manipulate it as I want and display all products which is added to chart Maybe it is so easy and so common but somehow I couldnt find it out since morning = )) I hope it saves someone's hours
THE QUESTION WAS:
I am building an onlineshop and What I want to do is displaying all clicked products in showChart page.(a very simple page which shows you the products that you added to your chart by clicking on chart_icon). I have tried some several common methods but I couldnt manage to do it somehow. My last desperate try was creating this addToChart() function.
Since setting the cookie part works good I simplified the code and paste just the important parts (in my opinion). Any kind of help or suggestions would be appreciated. I dont expect anyone to write the code for me.
thanks in advance
for($i=0;$i<$num;$i++)
{
$ftc = mysql_result($result, $i, "product_image");
$ftc2 = mysql_result($result, $i, "product_id");
$ftc3 = mysql_result($result, $i, "product_name");
$ftc4 = mysql_result($result, $i, "product_preis");
$ftc5 = mysql_result($result, $i, "product_old_preis");
echo "<a href='details.php?product=".$ftc2."'><div class='products_list'>
<img width='217px' height='323px' src='".$ftc."'/>
<div class='alt_yazi2'><b>".$ftc3 ."   <font
style='float:right;'>".$ftc4."TL  <b style='text-decoration:line-through; float:right;'>".$ftc5."TL </b></font></b></a>
</br>
<div id='sepet'><a id='cookie' onclick=\"SetCookie('"cookie_product"', '".$ftc2."', 'expiry');\" href='#'>
<img width='35px' height='25px' src='images/cart_icon.png'/>
JAVASCRIPT CODE BEGINS HERE
var today = new Date(); var expiry = new Date(today.getTime() + 365 * 24 * 60 * 60 * 1000);
function getCookieVal (offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1) { endstr = document.cookie.length; }
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg) {
return getCookieVal (j);
}
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name,value,expires,path,domain,secure) {
document.cookie = name + "=" + escape (value) +
((expires) ? "; expires=" + expires : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}
document.getElementById(cookie).onclick = function addToChart()
{
var cookieValue = document.getElementById(cookie).value;
var cookiearray = new Array();
cookiearray = cookieValue.split(",");
return cookiearray;
}
Ok I have solved my problem with PHP. Its so specific but I want to share it in case somebody needs it.
First of all I didnt give any specific name as product_id for the cookie but I just give the variable of the product_id "$ftc2" which is clicked, shown as below
onclick=\"SetCookie('".$ftc2."', '".$ftc2."', 'expiry');
So whenever user clicks on any product, a new cookie is created with the name of the product_id like name=2 or name=32 whatever.
then I have created a foreach on the chart page as below
<?php
foreach($_COOKIE as $cookies)
{
echo $cookies;
}
?>
It displayes now all stored cookie values(in my case product ids) and now I can manipulate it as I want and display all products which is added to chart
Maybe it is so easy and so common but somehow I couldnt find it out since morning = ))
