I've used it sucessfully many times. It may the other person's unfamiliarity with arrays and variables

I created the below function which will handle both single choice and multiple choice drop down values and mark them as selected when the user views that drop down again.


function my_select($name,$rows,$multiple,$array_list,$match)
//this select box takes the above 5 arguements to create details
1. $name = the name of the select box
2. $rows = the number of displayed rows (1 as the default)
3. $multiple = does the select allow multiple choices (boolean value 0 for no, 1 for yes
4. $array_list = the options (in a value:display pair ie "1:Informatique","2:Voyages","3:Immobilier")
5. $match = the items to be selected if trying to keep a value ( is "" if no values present or comma separated list if multiple)


 $numOpts = count($match);
 if ($numOpts>1){
 }elseif ($numOpts==1){

echo "<select name=\"$name\" ";
echo "size=\"$rows\" ";
if ($mutiple==1){ echo " MULTIPLE "; }
echo ">";


for ($i=0;$i<$count;$i++){
  //take apart the array key:value pairs
  $elements = explode(":",$array_list[$i]);

  //compare matches to list to see if the item is selected
  if (($numOpts<2)&&($matches == $elements[0])){
     echo "<option value=\"".$elements[0]."\" SELECTED>".$elements[1];
     echo "<option value=\"".$elements[0]."\" SELECTED>".$elements[1];
     echo "<option value=\"".$elements[0]."\">".$elements[1];
}//end for
echo "</select>";

}//end function

I was just told that having an array pulling multiple
selections from a user out of a list box is a bad

Can this be true ?
I was under the assumption it was perfectly effective.

Thank you, Stuart
