i am creating a friend request system that allow user to send request to each other to add as friends like facebook and i have 2 conditions that if :
- the user is the profile owner he can not add him self i will echo an error msg
- the user is not the owner of the profile it will echo a message that say wait then the request is send
if the user has already send the request i will echo a message to infor the user that a request had been send.
but the error is that i am in the first condition because the system display that the user is the owner profile but this is wrong
can anyone help me ??
this is a chunk of code
function addAsFriend(a,b){
//alert("Member with id:" + a + "request friendship with the memeber with id:" + b);
var url = "script_for_profile/request_as_friend.php";
$("#add_friend").text("please wait...").show();
$.post(url,{request:"requestFreindship",mem1:a,mem2:b},function(data){
$("#add_friend").html(data).show().fadeOut(12000);
});
}
<div class="interactContainers" id="add_friend">
<div align="right"><a href="#" onclick="return false" onmousedown="javascript:toggleInteractContainers('add_friend');">Cancel</a></div>
