[PHP] two dimensional array or two arrays?

[Tom Beidler]

I have some code I use to create pulldown menus. It's as follows;

$categoryarry = array(,1,2,3,4,5);
while (list($key,$value) = each($categoryarry)) {
  if ($value == $srch_cat) {
$cat_option .= option value=\$value\selected$value/option\n;
  } else {
$cat_option .= option value=\$value\$value/option\n;
  }
}

It works fine when the pulldown value and displayed text are the same, ie.

option value=JohnJohn/option

But now I would like to change so the value is different then what's
displayed in the menu, ie.

option value=1John/option

I've never used two dimensional arrays but I thought it might be what I need
to look into. Or should I have to arrays and use one for the value and the
other for the item displayed in the pulldown menu.

Any help appreciated.

Thanks,
Tom

this should do it for you.

$categoryarry = array(array(,none),array(1,John),array(2,Jim));
foreach($categoryarray as $value) {
  if($value[0] == $srch_cat) {
$cat_option .= option
value=\$value[0]\selected$value[1]/option\n;
  } else {
$cat_option .= option value=\$value[0]\$value[1]/option\n;
  }
}

Your $categoryarry is a 2d array, try :

  print_r($categoryarry);

But, I think you want to do :

  $categories = array('Sasheen','Tom','Fred');

Now, if you do this :

  while(list($key,$value) = each($categories)) {
  
print $key : $value\n;
  }

You'll get :

  0 : Sasheen
  1 : Tom
  2 : Fred

Could also define your array like so :

  $categories = array('a' = 'foo', 'b' = 'bar');

Which, if run through our loop above, will give us :

  a : foo
  b : bar

See?  Play with it a bit, it'll start to make more and more sense.

Regards,
Philip
