[thelist] RE: Arrays and Multiple Select?

[Les Lytollis]

Name your select box "Type_Of_Event[]" and bingo! php knows it has an array
to handle

Incindentally, if you use $HTTP_POST_VARS as the array in the while loop,
you can see exactly what your form is posting.

<TIP Type="PHP" Author="Lez">
If you often use n-dimensional arrays in your code this is a handy little
helper function you can use to see what going on

<pre>
  <?php
    function get_array_elems($arrResult, $where = "array") {
      while(list($key,$value)=each($arrResult)) {
        if (is_array($value)){
          get_array_elems($value, $where . "[$key]");
        }
        else {
          echo "$key=$value<br>\n";
        }
      }
    }  
  ?>

</pre>
