php recall

Heres another problem that may be impossible

PHP Code:


elseif((($opt=="a")&&($id)) or ($opt=="b")){             print("

can I print dependant on the results?

ie if id is odd print this
if id is even print that

If you understand what I am trying to do you must be psychic

If it is possible How do I do it?

I did a little fix with the PHP bbcode..

I've seen some the code you want in some user note on php.net.

But i can't find it now...

I think google must be used for this

When I find it, I'll post it

Thanks Allowee this is a great cause of frustration at the moment

I know what I want but getting it is another matter.

Sorry, I am not psychic

I didn't understand your question... the solution may not be as simple as this but I thought I'd give it a shot:

PHP Code:


<?php

elseif( (($opt=="a")&&($id)) or ($opt=="b") )
{
  $prt_str = ( $id%2 ? 'is Odd' : 'is Even' );
  echo $prt_str ;
}

?>

sorry for being so vague:-?
I want to search a table that stores player stats. The details of the players are similar but the points are worked out on there position. ie Goalie or Striker
What I want to do is if a player whos position is Goalie is called by the select menu rather than printing all the columns in the row it just prints the relevant columns that I want displayed. Alternatively if Striker is selected the relevant columns are printed for that position.
At the moment on the selection of either position all the columns are displayed for both position. This can be a little confusing for the viewer.

??:
Is that clear as mud now?

Unfortunately your 'clear as mud' explanation made it even worse, if before I thought I understood, now I am certain I don't!

Perhaps if you try to explain what you're trying to with some pseudocode that might help.

OK deep breath..... and here we go

PHP Code:


if ($opt=="teamplayerstats")
                    {
                    $stats = mysql("$db","SELECT * FROM players,stats,actplayers WHERE players.team = '$id' and players.id=actplayers.id and actplayers.active='1' and stats.season='$se' and stats.playerid=players.id");                
                    }
                else
                    {
                    $sql="SELECT * FROM players,stats,actplayers,teams WHERE players.position = '$position' and players.id=actplayers.id and actplayers.active='1' and stats.season='$se' and stats.playerid=players.id and players.team=teams.id and teams.division='$divname'";
$stats = mysql("$db",$sql);                
                    }
//$stats = mysql("$db","SELECT * FROM players,stats WHERE stats.playerid=players.id");                
$totalplayers=mysql_numrows($stats);
$j=0;
while($j < $totalplayers) 
{
$hname = mysql_result($stats,$j,"name");
$hid = mysql_result($stats,$j,"id");
$position = mysql_result($stats,$j,"position");
$manofthematch = mysql_result($stats,$j,"manofthematch");
$games = mysql_result($stats,$j,"games");
etc 
etc

OK now if position Goalie is selected how do I get for example just games and manofthematch to print and if Striker is selected just name, position and id to print?

Or is it impossible without extensive rewritting, a bottle of jack daniels and wall to bang my head against?

Hope this as cleared the mud a little or have I now turned the light off as well?

Actually I am still lost... but based on your last few sentences (inside your last post), I think you should think about something like this; just so you keep your code clean, clear and easier to manage:

You're trying to do 2 things based on different selects? So, I assume this is off a form? Try incorporating a 'hub' function (for lack of a better term); let's say we name it : process_player()

PHP Code:


<?php

function process_player()
{
  switch( $_POST['position'] ) // 'goalie' or 'striker'
  {
    case 'striker' :
      $html = do_striker_stuff(); // do specific stuff for this player in a custom function
      break;
    case 'goalie' :
      $html = do_goalie_stuff();  // do specific stuff for this player in a custom function
      break;
  }
  return( $html );
}

// the script now may look something like this:

if( isset($_POST['position']) )
{
  echo process_player();
}
?>

(screwing top onto bottle of jack daniels and removing head from wall) That looks like what I want to do.

I will give it a go and see how long it takes before the top comes off again.

Thanks JdS

Couldnt get it to work using the methos you suggested

BUT

Got it to work using

PHP Code:


{if ($position==Offensive){print(" <table

etc for each position.
but my code is now really messy

??: but who cares as long as I know what it is doing

Now for the next problem

I want to limit my calculations

PHP Code:


if ($games)
{$pperg=$points/$games;
$gaa=$goals/$games;}

how do I limit the number of decimal places and get it to round up or down? Sorry to ask so many questions but I always seem to get so far and then hit a full stop or the wall again
