Please help to fix this issue with like counting.i create a news feed like facebook using php mysql and ajax.
problem is that when i click on like button it prints like count from (this value) and showing to all, let say i have 5 posts and like current value for different posts are 100, 200 , 70 , 80 , 578. when I click on first post ajax success count 100+1 = 101 for first post and for all other post printting same 101 likes. now if i will go to 2nd post and its like value 200, ajax will show 200+1 =201 like. so after click on 2nd post all 5 posts like will show 201. its creating problem for me. I understand that after ajax success i mentioned to show the value to div class (.ajax_like_result), thats why its showing in every post, same result until i am not clicking on different post.
how to fix this so that when I click on any post it wil show only its real like value??
I try to change the DIV attribute id , instead of class then it only works for first post. other post totally not working. if i set div atribute to class then like is working but printing incorrectly as i mentioned above.
I have pasted below- html , php and ajax code . thanks for your help.
