datepicker calendar uses javascript and php
On the checkout page I have successfully replaced the original 'Customer Notes' and added a new field there by following cherie's excellent directions in this post: http://forum.x-cart.com/viewtopic.php?t=9400&postdays=0&postorder=asc&high light=change%20order%20details&start=15 Now I would like to add a datepicker - a small popup calendar to pick a date - that will enter the chosen date into a text field (my new field). The original script consists of 3 php files as follows:
main.php
Code:
<html>
<head>
<title>Example of Datepicker</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body bgcolor="#eeeeee" text="#000000"><Script Language="JavaScript">
function showCalendar(frm,textbox){
window.open("Calendar.php?frm=" + frm + "&txt=" + textbox,"DatePicker","width=250,height=230,status=no,resizable=no,top=200,left=200");
}
function getObject(obj){
alert(obj.value);
}
</Script>
<form name="frm">
<input type="text" name="txtCalendar">
<button type="button" onclick="showCalendar('frm','txtCalendar')">Click for Date</button>
</form>
</body>
</html>
Calendar.php
Code:
<?php
include 'DatePicker.php';
//Get form and textbox from calling paging
$frm = $_GET['frm'];
$txt = $_GET['txt'];
?>
<html>
<head>
<title><< Delivery Date Calendar >></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<Script Language="JavaScript">
function getSelDate(SelDate){
var frm,txt;
frm = '<?php print "$frm" ?>';
txt = '<?php print "$txt" ?>';
window.opener.document.forms[frm].elements[txt].value = SelDate;
window.close();
}
</Script>
</head>
<body bgcolor="#999999" text="#000000">

This all works great when all pages are in the same directory. Now to make it work with my XCART!!! So... I have added the following to skin1/customer/main/checkout_notes.tpl:
Code:
<TR valign="top">
<TD>{$lng.lbl_delivery_date}:</TD>
<TD></TD>
<TD nowrap>
{include file="datepicker/datepicker_js.tpl"}
<form name="frm">
<input type="text" name="txtCalendar">
<button type="button" onclick="showCalendar('frm','txtCalendar')">Click for Date</button>
</form>
</TD>
</TR>
have added the folder skin1/datepicker and the template file skin1/datepicker/datepicker_js.tpl as follows:
Code:
{literal}
<Script Language="JavaScript">
function showCalendar(frm,textbox){
window.open("datepicker/Calendar.php?frm=" + frm + "&txt=" + textbox,"DatePicker","width=250,height=230,status=no,resizable=no,top=200,left=200");
}
function getObject(obj){
alert(obj.value);
}
</Script>
{/literal}
and added the folder xcart/datepicker with the two files Calendar.php and DatePicker.php in this folder.
So now on the checkout page there's a text box and a "Click for Date" button. Onclick a calendar window pops up. Good so far! When I click a date on the calendar I get a javascript error:
Code:
Error: window.opener.document.forms[frm] has no properties
Source File: http://mywebsite.com/xcart/datepicker/Calendar.php?frm=frm&txt=txtCalendar
Line: 11
Any ideas on how to make this work? Many thanks in advance for your help! |
