mysql statement help!!!

[mrcniceguy]

i have this weird problem and i dont know how to make it work.
the problem appears after i consider the OR statement.without or statement the first part is working .
So idont how to use this statement in mysql.
i hope someone can help me.
Down is my script.

$po=$_POST['postid'];
$poster=$_POST['poster'];
$user=$_SESSION['user'];

 $checkz=mysql_query("SELECT DISTINCT poster FROM postcomment WHERE ((postid='$po') and (poster !='$poster')) OR ((postid='$po') and (poster !='$user'))"); 
         $countt=mysql_num_rows($checkz);	
		 
		 if($countt>0){
		 
		   while($row=mysql_fetch_array($checkz)){

		   $postern=$row['poster'];
                echo" $postern<br/>";
             }
}

my problem is here

$checkz=mysql_query("SELECT DISTINCT poster FROM postcomment WHERE ((postid='$po') and (poster !='$poster')) OR ((postid='$po') and (poster !='$user'))");

i eve tried this but didn`t work either.

$checkz=mysql_query("SELECT DISTINCT poster FROM postcomment WHERE ((postid='$po') and ((poster !='$poster')  or (poster !='$user')));

I couldn't notice anything wrong in the query. Did you check the result only for the second part like the following and get the results you expected ?

$checkz=mysql_query("SELECT DISTINCT poster FROM postcomment WHERE   ((postid='$po') and (poster !='$user'))");

[mrcniceguy]

yeah!when i checked the result for the second part i got the result i expected.
Thats why i`m wondering what might be wrong here wit the OR statement.

[CFROG]

The query looks fine, what is the difference between $poster and $user ?

[mrcniceguy]

Actually i`m trying to send notifications to people.
$poster is the owner of the post and $user is the one commenting,which means the logged in member which can happen.
so below is my whole script....when i was writing it seemed to be fine but when i started to test it ,is when i experience this weird problem.
So the problem is in line 63-64.
other parts of the script are fine even the DISTINCT FUNCTION ALSO OK.

<?php   session_start();
include"config.php";
$user=$_SESSION['user'];
$userid=$_SESSION['id'];
$names=$_SESSION['name'];

if(isset($_POST['submitpostcomment'])){

$po=$_POST['postid'];
$poster=$_POST['poster'];
$comment=$_POST['comment'];


$query = "INSERT INTO postcomment  SET comment='$comment',poster='$user',postid='$po'" ;
$result=mysql_query($query);
$statusid2= mysql_insert_id();
    if($result) {

     echo"Comment posted successfully<br/>";
	 
	 
	 //NOTIFICATION TO THE PEOPLES
 //select the gender of the poster to be used if his/her commenting own photo
 $ddaaa=mysql_query("SELECT genders FROM  profile WHERE users='$user'");
       $sszz=mysql_fetch_array( $ddaaa);
        $jinsia=$sszz['genders'];
	    if($jinsia==p){
		$jinsia='his';
		}else{
		 $jinsia='her';
		}
 
 
 
 
   //check to see if the one commenting is the owner of the post
     if($poster!=$user) {
	 
      	 
    //select email of the owner of post
      $dd=mysql_query("SELECT emails,genders FROM  profile WHERE users='$poster'");
       $ss=mysql_fetch_array($dd);
       $owneremail=$ss['emails'];
	   
	   //INSERT INTO NOTICATION TABLE
	  mysql_query("INSERT INTO notification SET type='post',action='commented your post',typeid='$po',sender='$user',receiver='$poster',status='0'");

You could try something like this:

$array = array($user, $poster);

$checkz=mysql_query("SELECT DISTINCT poster FROM postcomment WHERE postid='$po' AND poster NOT IN ('".array($array)."')

[mrcniceguy]

okey=))i will try this and inform you .

[mrcniceguy]

This also didn`t work.
What its doing is taking all poster frm where id=$post without considering $array .
this is what i`m also getting with my script.
If u have time for this please can u test it for me .
i mean u create a simple comment system where all people who comments will be notified when somebody else comment including the owner of the comment.
sometimes i think may be mysql have changed their commands .why is OR and NOT IN not working ?

[Manuz]

Hey ..
1. Try to echo out the query and paste it in mysql.......
2. r u getting any error?
3. whether the output of the query returns null or any value...

[mrcniceguy]

i`m not getting any error!!!
when i echo the result it gives the values names of all the poster where id='$po' which is postid.
what i want is to exclude the $user the logged member and $poster the owner of the poster in my query.
ACTUALLY its VERY STRANGE error! thats why i`m asking if somebody can test it for me...to see where i`m going wrong.

[Manuz]

Hey,
So i think you got the required result , but need to removal something for this rit?
Whether you need to remove $user and $poster from the result or query ?
Or explain me what s ur requirement or output

[CFROG]

Maybe you can try AND instead of OR and see what that does.

[daryll1]

Should it not be,

$checkz=mysql_query("SELECT DISTINCT poster FROM postcomment WHERE postid='".$po."' AND ((poster !='".$poster."')  OR (poster !='".$user."'")));

I can't see what the extra brackets were doing and I capitalized the AND and OR, I find it easier to read the statement then.

[mrcniceguy]

@CFROG,its unbelievable....after i tried the AND instead of OR everything worked as i wanted..

$checkz=mysql_query("SELECT DISTINCT poster FROM postcomment WHERE postid='".$po."' AND ((poster !='".$poster."')  AND (poster !='".$user."'))");

when u suggested that,i didn`t even test coz for me it did not sound correct.
Just today decided to try it,and this is just bcoz there was no way i could solve this question(tried alot of tricks) And HURAAAAAAAAAAAAAAAAAAA it worked.
THANKX TO ALL WHO CONTRIBUTED ON THIS THREAD.

[CFROG]

LOL ... now that hurts, you didn't even try it.

[mrcniceguy]

yeah man!i`m sorry.
i was very sure that the OR can`t be replaced by AND...
i real appreciate for ur suggestion.
