Buenas
Recién empiezo yo tb con AJAX, y estuve usando la clase
xajax
Si vas a usar esa clase, podrías usar el siguiente código, adaptando la función agregar a tus necesidades de MySQL
Código PHP:
<?php
require ('xajax.inc.php');
class myXajaxResponse extends xajaxResponse
{
function addCreateOption($sSelectId, $sOptionText, $sOptionValue)
{
$this->addScript("addOption('".$sSelectId."','".$sOptionText."','".$sOptionValue."');");
}
function addCreateOptions($sSelectId, $aOptions)
{
foreach($aOptions as $sOptionText => $sOptionValue)
{
$this->addCreateOption($sSelectId, $sOptionText, $sOptionValue);
}
}
}
function agregar($tabla)
{
$objResponse = new myXajaxResponse();
if ($tabla == 1) {
$aOptions['One'] = 1;
$aOptions['Two'] = 2;
$aOptions['Three'] = 3;
} else {
$aOptions['Four'] = 4;
$aOptions['Five'] = 5;
$aOptions['Six'] = 6;
}
$objResponse->addCreateOptions("select1",$aOptions);
return $objResponse;
}
$xajax = new xajax();
$xajax->registerFunction("agregar");
$xajax->processRequests();
?>
