thanks for the response daniel.<br>
<br>
i figured this out shortly after i posted the question.<br>
<br>getting the symbols by id [1 ... numSymbols] does indeed work.<br><br>ak<br><br><div class="gmail_quote">On Thu, Apr 3, 2008 at 12:00 PM, Daniel Morissette <<a href="mailto:dmorissette@mapgears.com">dmorissette@mapgears.com</a>> wrote:<br>

<br>
i would also like the user to be presented with a list of all the symbols defined in the mapfile that i am working with. i have gone through the API but haven't come across any functions that will allow me to accomplish this. does such functionality exist in the API?<br>

The mapObj's getNumSymbols() and getSymbolObjectById() methods should allow you to do something like this (untested):<br>
<br>
<br>
$numsymbols = $map->getNumSymbols();<br>
<br>
# Start looping at 1 since symbol 0 is the default symbol<br>
for ($id=1; $id < $numsymbols; $id++)<br>
{<br>
$symbol = $map->getSymbolObjectById($id);<br>
# Do something with $symbol here... see the symbolObj class docs...<br>
}<br>
