Re: [PHP] two dimensional array or two arrays?

[Philip Olson]

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.

Philip

[Anton Stroganov]

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) {
$cat_option .= "$value[1]\n";
  } else {
$cat_option .= "$value[1]\n";
  }
}

[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) {
$cat_option .= "$value\n";
  } else {
$cat_option .= "$value\n";
  }
}

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

John

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

John

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
