I have a problem with my join tables works inside sql

      $sel_ms="SELECT * from users INNER JOIN likes ON users.id=likes.user_id and likes.post_id='$id'";

i have a problem with my code when i type this sql on database as for example

      $sel_ms="SELECT * from users INNER JOIN likes ON users.id=likes.user_id and likes.post_id='470'"; 

it returns true i mean two person who have liked my post but inside my brauzer i faced with the problem and can not find exact persons who liked it it shows me all USERS I am passing parameters properly and it works for each post and for each button those are the files which i worked on maybe i have a proble with loops but i do not know why it is not returning me the exact users?

> And span which holds id=$id and button modal this contains id of each post when i click it returns me the id of each post

    <div id="loaded_msg">
          <form method="POST">
          <p>

            <?php

             echo"
               <button type='button' id='#exampleModal' class='btn btn-primary' style='margin-left:530px; margin-top:-35px;' data-toggle='modal' data-target='#exampleModal'>
                 +
                </button>";

        ?></p>
    </form>
        </div>

wHEN i click on button it should return me users who has liked it 

database looks like this

    table->likes has (l_id,post_id,user_id)
    table->users has (id,f_name,etc)
