How to write a code of a combobox

Hi,

Try this code:

Combo-BOX - Abstraction With function you can retrieve the combo-box
structure with its data
<?php
function GetCombo_Where($db, $nombre, $tabla, $campo_lista, $campo_graba,
$campo_seleccionado,$valor_seleccionado,$where)
{
$query="SELECT * FROM $tabla ";
$query.=($where)?"WHERE ".$where:"";
$db -> query ($query);
$cant_registros = $db -> num_rows ( );
$string = "<select name=".$nombre.">";
if ($seleccionado=="")
$string .="<option></option>";
for ($i=1;$i<=$cant_registros;$i++)
{
$db -> next_record ( );
$value = $db -> Record[$campo_graba];
if ($valor_seleccionado == $db -> Record[$campo_seleccionado])
$string .= "<option selected value = ".$value." >";
else
$string .= "<option value = ".$value." >";
$string .= $db -> Record[$campo_lista];
$string .= "</option>";
}
$string .= "</select>";
return $string;
}
?>
hope this helps.

Thanks
