Question

Good day,

I’m having a ton of trouble with the following php code,
the pseudo code for it as follow:

Check if a relationship exists in the table
if it doesn’t exist add a relationship to the table.
otherwise get the current relationship and return it.

the code goes as follow:

    $result = mysql_query("SELECT * FROM friends WHERE (user_id = '" .$me. "' AND user_id2 = '" .$other. "') OR (user_id2 = '" .$me. "' AND user_id = '" .$other. "')");
if($result == false){
    mysql_query("INSERT INTO `friends`(`user_id`, `user_id2`, `status`) VALUES ('" .$me. "', '" .$other. "', 'pending')");
    echo("Friend Request Sent"); 
}
else{
    $res = mysql_query("SELECT 'status' FROM friends WHERE (user_id = '" .$me. "' AND user_id2 = '" .$other. "')");
    $rows = array();
    while($r = mysql_fetch_assoc($res)) {
        $rows[] = $r;
    }
    echo json_encode($rows); 

}

Thanks in advance

Answer 1

you should try the below if condition

if(mysql_num_rows($result)){
     mysql_query("INSERT INTO `friends`(`user_id`, `user_id2`, `status`) VALUES ('" .$me. "', '" .$other. "', 'pending')");
     echo("Friend Request Sent"); 
}

and also else block should be same as first query, and it should look like

else{
    $res = mysql_query("SELECT 'status' FROM friends WHERE (user_id = '" .$me. "' AND user_id2 = '" .$other. "') OR (user_id2 = '" .$me. "' AND user_id = '" .$other. "')") ;
    $rows = array();
    while($r = mysql_fetch_assoc($res)) {
       $rows[] = $r;
    }
    echo json_encode($rows); 
}
