如果我们有一些像(“http://example.com?s=12&p=13&w=14”)这样的链接来分享它以及如果你的网站的网址是如何添加whatsapp共享按钮

After sharing the URL in whatsapp, it was not complete. It picks the URL up to ...http://example.com?s=$sender. After $sender, the URL end was not there.

<a class='' href='whatsapp://send?text=<?php echo "http://example.com/?s=$sender&r=$receiver&d=$d&m=$m"; ?>' data-action='share/whatsapp/share'>Share</p></div></a>

I was expecting the url (http://example.com?s=$sender&r=$receiver&d=$d&m=$m)

but I only got (http://example.com?s=$sender) in the whatsapp chat.

What is the solution to my problem?

you should learn how to concat between text and php

if you have variable var and equal to Abanoub

$var = "Abanoub";

and you want to echo hello $var you should do it as:

echo "Hello " . $var;

we use "." to concat between text and php var so you should write

<?php echo "http://example.com/?s=".$sender."&r=".$receiver."&d=".$d."&m=".$m; ?>

One solution I found. We can use the encoded URL in the WhatsApp link instead of decoded URL. I think used URL encoder in PHP.
