Help with if elseif

[Cornhusker40]

echo "Next Increment Number: $next_increment<br><br>";

 

if ($next_increment <="10") {

  echo "Chapter 1";

} elseif ($next_increment >="11" || $next_increment <="20") {

  echo "Chapter 2";

} elseif ($next_increment >="21" || $next_increment <="30") {

  echo "Chapter 3";

} elseif ($next_increment >="31" || $next_increment <="30") {

  echo "Chapter 4";

}

 

What I am attempting to do is to obtain the next ID number for the mysql table field and set the chapter field accordingly as per the portion of the script above.

Currently the $next_increment = 21, but when I run my script it displays Chapter 2, not Chapter 3?

I have checked the tutorials/help, etc. couldn't find any similar situations.

Can anyone help me?

Tks

because your condition is true where $next_increment >="11" .. 21 is greater than or equal to 11.

 

You probably mean to use && instead of || 'cause right now you have:

 

elseif ($next_increment >="11" OR $next_increment <="20")

 

So, either condition can be true, doesn't have to be both.

Change || to &&.

 

Your IF conditions state $next_increment >= "11" || $next_increment <= "20".  This says IF next_increment is morethan or equal to 11, echo Chapter 2.  At this point, $next_increment IS more than 11 therefore it displays "Chapter 2" as the line meets the first condition and doesnt have to meet the 2nd one.

 

If you Change || (OR) to && (AND) then it has to be >= 11 AND <= 20.

Tks jd307 - how obvious!
