retain input data on page reload

[bluerain25]

hi guys,

somebody help me please i need to know how to retain any input on page reload. I have 2 chained combo box (province and city) when a user choose a province, the next combobox should be populated. I use a script that reload the form to execute a query that filters the cities under that province. I was able to do that but the input data were gone on reload. do anyone have a sample code that will retain all the input data?

thanks in advance

Hey, It is easier if you show us a sample of your script source, so we could help. However

Assuming I have this two elements

Choose CityOhioDenver

Then my Php code may look like:
<?php
require "form_class.php" ;

if(array_key_exists("push",$_pos,)){
if($_POST["cboCity"] == "-1")){

echo " You have not selected a city!";
//Call my Print form function
$formdisp = new form ;
$formdisp ->displayform($_POST["cboCity"]) ;

}

}

?>

I am been a bit OOP Compliant here and assume that you have a form class which you created and invoke. don't mind my MVC paradigm.

hope this helps else post ur script for me here.
