Array Help

Hightower · 08-25-2009, 04:28 PM

I have another thread ongoing about sorting an array, but I have a couple of other things I would like to achieve if anybody can help me:

1) Lets say I have an array of 10 items. I only want to show 5 items on the screen. These 5 items will vary, so it might be items 1-5, or items 2-6 or items 4-8 etc. To make it easier to understand, think of a league table. Now I only want to show the two records above, and two records below based on my team of choice:

Pos 3: Team 1
Pos 4: Team 2
Pos 5: My Team
Pos 6: Team 4
Pos 7: Team 5

(Notice how positions 1-2 and 8-10 are not shown)

2) I need to echo the name of each key for the positions in the table. So lets say my array is:

PHP Code:


			
array ([1] => Team 1, [2] => Team 2, [3] => Team 3 //and so on

And I start my table snippet at position two. By echoing the key I show the position of that team - I just don't know how to do it.

Sorry if it's a bit of a mouth full, but any help is greatly apprecfiated!

Many thanks,

You could set up a combobox/textbox that asks for what starting rank you want, and another for how many they want listed.

PHP Code:


			
$rank = $_POST['rankcmb'];

$listing = $_POST['listingCmb'];

$i = 0;

foreach($yourTeamArray as $tRank => $team){

 if(){ //need to grab $rank*

  while($i <= $listing){

    echo $team;

  }

 }

}

*- need to grab $rank and compare it to the keys in the array ($tRank). I am assuming you are building an array the puts the teams in rank order. Once you compare the two, it should put the pointer at that position and just print out the teams...
