I am using wordpress site and sending user to open a particular chat on whatsapp. Its working fine in case of simple text send like this:
<a href="whatsapp://send?text=Hi" class="wabtn">Chat</a>
But i want to let the users to open a particular contact. I have seen this functionality in iOS but dont know weather its also applicable in php or not. Here is the code i am trying:
<a href="whatsapp://send?abid=9226266566&text=Hi" class="wabtn">Chat</a>
There are the links that i found for help:

What you are mentioning is NOT dealing with PHP, since PHP is a server-side language and you are only dealing with HTML (client-side).
Nevertheless, that being said, you should better use the official solution that replaces ABID need. I’ve mentioned it and another schema solution that also seems to be working (july 2017) in THIS OTHER ANSWER (because S.O. policies I had to put a link to the solution, no duplicates).
