Currently working on a share button for Vk however having a dynamic site, I need the button to automatically use the correct page URL.
This is the code snippet they offer for a static site, how could I adjust this for multiple pages ?
<a href="http://vk.com/share.php?url=http://example.com" target="_blank">
最简单的方法是通过 JavaScript:
document.getElementById("vkShare").href = 'http://vk.com/share.php?url='+document.location.href;
<a id="vkShare" target="_blank">Share to VK</a>
您可以使用像这样的窗口对象来获取当前页面的 URL: window.location.href
。
simple works on all sites
function share(){ function copyToClipboard(text) { window.prompt('share us',text); } copyToClipboard(window.location.href); }
<button onclick="javascript:share();">share </button>
Using php to get the url, try to use $_SERVER['HTTP_HOST']
to get the host and $_SERVER['REQUEST_URI']
to get any query string attached to the url.
<?php $uri = $_SERVER['REQUEST_URI']; $host=$_SERVER['HTTP_HOST']; //$complete_url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; //To use whether HTTP OR HTTPS if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === "on"){ $htp = "https"; }else{ $htp = "http"; } $complete_url = $htp."//:".$host.$uri; ?> <a href="<?=$complete_url?>" target="_blank">
