[SOLVED] If Queries

[supanoob]

Ok so i have the followng if query but it doesnt seem to be working. Basically i want to check to see if they person is at one of 2 places by checking the co_ord_y and co_ord_x.

 

<?php

if ($town == '1')
{
if ($co_ord_y != '14' && $co_ord_x != '20' || $co_ord_y != '19' && $co_ord_x != '15')
{
echo "You are no longer near a river.";
DIE();
}
}

?>

 

Well everytime i get to one of the coords it throws the "You are no longer near a river."

What do you expect to happen? And where do you set the $co_ord_y and $co_ord_x variables?

 

ps: There called statements, not queries. And integers should not be surrounded by quotes, this makes them strings.

the coords are set in the database when someone moves from 1 place to another, and if they are at the right places i want the grid for them to fish on to be shown. removing the 'from the numbers didnt help any.

If your recieving the message echo 'You are no longer near a river', it is because your if statement returns true. Simple.

 

I don't know what you want.

i only want it to show when they are not on those coords if you know what i mean? so when they are not on  20x 14y or 15x 19y

Try this.

 

<?php

if ($town == 1)
{
if (($co_ord_y != 14 && $co_ord_x != 20) || ($co_ord_y != 19 && $co_ord_x != 15))
{
echo "You are no longer near a river.";
DIE();
}
}

?>

 

[supanoob]

nah that didnt work ><

[trq]

What does this output?

 

<?php

die("y = $co_ord_y x = $co_ord_y");
if ($town == 1) {
  if (($co_ord_y != 14 && $co_ord_x != 20) || ($co_ord_y != 19 && $co_ord_x != 15)) {
    echo "You are no longer near a river.";
    die();
  }
}

?>

[supanoob]

y = 14 x = 14

 

ummm, thats abit strange, even in the database it says 14y 20x

[MmmVomit]

Actually, this should do it

 

<?php

if ($town == 1)
{
if (($co_ord_y != 14 || $co_ord_x != 20) && ($co_ord_y != 19 || $co_ord_x != 15))
{
echo "You are no longer near a river.";
DIE();
}
}

?>

 

[trq]

Hehe, because it was a typo on my part.

 

die("y = $co_ord_y x = $co_ord_x");

[supanoob]
