单击链接时单击计数器 PHP/JS
[英]Click counter when link is clicked PHP/JS
问题描述
I have a little script here that counts clicks when link is clicked and stores it in.txt file, but it works fine when I have only "click=yes" under href.
我这里有一个小脚本，可以在单击链接时计算点击次数并将其存储在 .txt 文件中，但是当我在 href 下只有“click=yes”时它工作正常。 But I can't make it to track clicks when I have link to external site.但是当我链接到外部站点时，我无法跟踪点击次数。
Here is my code:这是我的代码：
<?php
if(!file_exists('counter.txt')){
file_put_contents('counter.txt', '0');
}
if($_GET['click'] == 'yes'){
file_put_contents('counter.txt', ((int) file_get_contents('counter.txt')) + 1);
header('Location: ' . $_SERVER['SCRIPT_NAME']);
die;
}
?>

<body>
<h1><?php echo file_get_contents('counter.txt'); ?></h1>
<a href="http://www.google.com?click=yes" target="new">clickMe</a>
</body>
</html>
My guess is it has to do something with header('Location: '. $_SERVER['SCRIPT_NAME']);我的猜测是它必须对 header('Location: '. $_SERVER['SCRIPT_NAME']); 做些什么but I can't figure it out so I could really use some help.但我想不通，所以我真的需要一些帮助。
And is it somehow possible to have multiple links save to the same file, and when I show it on website it's sorted from largest number to smallest?是否有可能将多个链接保存到同一个文件，当我在网站上显示它时，它是从大到小排序的？ I have an idea how to do it with MySQL database but I can't use it at place where this will be implemented.我知道如何使用 MySQL 数据库来完成它，但我不能在将要实现它的地方使用它。
Thanks in advance!提前致谢！ Cheers!干杯!

Your server never sees the URI being accessed as the client leaves your page. 当客户端离开您的页面时，您的服务器永远不会看到正在访问的URI 。 To do something like this, it may be best to set up a redirect which works like this 为此，最好设置一个像这样的重定向
<a href="/goto.php?href=http://www.google.com" target="_blank">click me</a>
(Make sure the external site's URL is URL encoded as you're passing it as a GET component of a URL to your own page) （在将外部网站的URL的GET组件传递到自己的页面时，请确保外部网站的URL是经过编码的URL ）
Then in goto.php you store your click and send a redirect header 然后在goto.php存储点击并发送重定向标头
if(!file_exists('counter.txt')){
file_put_contents('counter.txt', '0');
}
file_put_contents('counter.txt', ((int) file_get_contents('counter.txt')) + 1);
header('Location: ' . $_GET['href']);
Now you can track these clicks, you can add your domain-specific counters in goto.php instead of your text file 现在您可以跟踪这些点击，可以将特定于域的计数器添加到goto.php而不是文本文件中

You could use Javascript to catch click on a link , send data via AJAX call. 您可以使用Javascript捕获链接的点击，并通过AJAX调用发送数据。 Here is small sample using JQuery. 这是使用JQuery的小样本。
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
$(
function() {
$('a').click(linkClicked);
}
);
//this funciton will be called on every click on any link on page
function linkClicked() {
var url = $(this).attr('href');
//call PHP script to save URL ./saveurlclicks.php?url=CLICKEDURL
$.get('./saveurlclicks.php', {'url': url})
//be sure to return true so user can navigate further
return true;
}
</script>
</head>
<body>
<a href='/some href' >asasa</a>
<a href="www.google.com" >google</a>
</body>
</html>
<?php
//saveurlclicks.php
// here we save links in file but using serialized array
// if you need to get count of links clicked ,
// have a second script that unserializes array and sort it in revers order
$url = @$_GET['url'];
$counterFile = 'counter.ser';
if ($url) {
if(file_exist($filename))
$links = unserialize(file_get_contents($filename));
else $links=array();
if (!isset($links[$url])) {
$links[$url] = 0;
}
$links[$url] ++;
file_put_contents($counterFile, serialize($links));
}

I love the simple solution by Paul S., but if you want to track the clicks with date, you can do something like this:我喜欢 Paul S. 的简单解决方案，但如果您想跟踪带日期的点击次数，您可以这样做：
03/03/2022 14
04/03/2022 2
<?php
$dateexists = false;
if(!file_exists('counter.txt'))
{ $fh = fopen('counter.txt', 'w');
fclose($fh); }
$datecounts = file('counter.txt', FILE_IGNORE_NEW_LINES);
foreach($datecounts as $key => $datecount){
list($date, $count) = explode("\t", $datecount);
$count = (int) $count;
if($date == date('d/m/Y'))
{ $datecounts[$key] = $date."\t".++$count;
$dateexists = true; }
}
if(!$dateexists)
{ $datecounts[] = date('d/m/Y')."\t1"; }
$fh = fopen('counter.txt', 'w');
if (flock($fh, LOCK_EX)) {
foreach($datecounts as $datecount)
{ fwrite($fh, $datecount.PHP_EOL); }
flock($fh, LOCK_UN);
}
else
{ //couldn't lock, might want to do stuff here }
fclose($fh);
header('Location: ' . $_GET['href']); // the redirect
?>
