Booking Dates


I'm familiar with easy php/mysql-applications, but i've run into a problem now. I'm trying to build a booking system(for training purpose), and I'm kind of stuck when it comes to this:

* each booking record in db has a "from" and a "to" date(DATE format)
* how can i return available objects when a user searchs for "available objects from 2006.01.01 to 2006.03.01 ?

Compare Two Dates In A Booking System
i want to compare two dates called booking_start_date and booking_end_date to make sure that the booking start date comes before the booking end date. at the moment both dates are just stored as dates in the mysql database. anybody know how i could do this?

and also does anybody know how i can find the number of days that the booking is for based on the dates that the user has entered as it will be needed for me to calculate the price of their overall booking.

Booking Code
i cant even get it to work in the browser at the moment it gives me the error:

Parse error: parse error, unexpected T_ELSE in C:APACHE2Apache2htdocsadd_book.php on line 91

which is the else in the lines which is before the form starts:

else {
$accommid = $_POST['accommID'];

i have confused myself completly with all the if's and elseif's and the brackets that go with each. however i am trying to do a booking script that will search to see if the dates that the users have entered are avaialable for a particular accommodation.

also i need to be able to solve the concurrent user problem to ensure that an accommodation cant be double booked. Code:

Ticket Booking System

2 - What do you do to release these 'seats' if someone closes their

Online Booking Calender
I wanted to put a calender on my website to allow people to see up coming clasess we have and allow them to booking/pay for them also. I would add them in the back end and how many spots are availble and when someone clicks on to pay for the class and checks out all the way it would subtract it from the total amount.

I would also like it to show on the date when all spots are gone Sold out and when only one is left only 1 spot left. I would like to see if there is a script out already that does this now. I am new to php/mysql so it would be great to find this.

Online Booking System
I've been scouring the web for an example, but just need pointing in the right direction. Ultimately I want to do this myself, just a simple booking system is required.

Essentially how the system works is that when someone comes to the show they need a website assessing. The first stage is to select an engineer which will carry out the assessment.

Once you have done this a screen appears with the available time slots with text fields which needs to be completed for that specific engineer to fill in the site requirements.

An idea perhaps is to create an online calender which I've already coded so that they can click on a specific date, and on the same page the time slots available.

Offering Dates And Booked Dates In A Table As DATE Datatype Using MYSQL.
Availability dates in offering dates except booked dates. For Example: Offering dates are :

01-09-2005 to 27-09-2005
01-11-2005 to 30-11-2005

Booked dates are :

10-09-2005 to 23-09-2005

Availability dates should be

01-09-2005 to 09-09-2005
24-09-2005 to 27-09-2005
01-11-2005 to 30-11-2005

we are looking for a slim open source course booking system with the
following features:
* users can enroll for courses, cancel their bookings
* maximum number of participants
* administrator's pages: list of participants and their contact details
(email, phone etc.)

So far, we have found an extension to the mambo CMS
http://mamboxchange.com/projects/akreservations/
and a rather smaller application (privately developed)

However, are there better alternatives?

Desired features:
* open source
* currently active development
* as "slim" as possible (mambo is quite a heavy weight!), may be even
without using a mysql database (like for example the slim version 1.x
of the gallery php application).

Checking Room Availability For Hotel Booking System
I was wondering if anyone could help me with a problem I'm having.
I've been using Dreamweaver to create a hotel booking system for a
friend of mine, using MySQL (version 4.0.21) and PHP 5. The bit I'm
struggling with is checking the Room Availability based on dates that
are typed into a textfield and then returning a list of the available
rooms on the next page.

The three tables involved in this function are:

CREATE TABLE `room` (
Room_Number tinyint(1) UNSIGNED NOT NULL,
Price_Double_per_Night decimal(5,2) NOT NULL,
Price_Twin_per_Night decimal(5,2) NOT NULL,
Price_Single_per_Night decimal(5,2) NOT NULL,
Price_Double_per_Week decimal(5,2) NOT NULL,
Price_Twin_per_Week decimal(5,2) NOT NULL,
Price_Single_per_Week decimal(5,2) NOT NULL,
PRIMARY KEY(`Room_Number`),
)
TYPE=InnoDB
ROW_FORMAT=fixed;

CREATE TABLE `room_booking_link_entity` (
Room_Number tinyint(1) UNSIGNED NOT NULL,
Room_Booking_ID int(11) NOT NULL,
Single_Double_Twin enum('Single','Double','Twin') NOT NULL,
PRIMARY KEY(`Room_Number`, `Room_Booking_ID`),

CREATE TABLE `room_booking` (
Room_Booking_ID int(11) NOT NULL AUTO_INCREMENT,
Customer_ID int(11) NOT NULL,
Bill_ID int(11) NOT NULL,
Date_of_Arrival date NOT NULL,

I've just discovered that MySQL 4.0.21 does not support subqueries.
I'm basically stuck with this version of MySQL. I think I've got
round the subquery problem by using a multi query option as follows:

1.Create a temptable that will store all of the room numbers that
have bookings for the particular dates requested as follows:

SELECT DISTINCT a.room_number INTO temptable
FROM booking_link_entity AS a INNER JOIN room_booking AS b
WHERE b.departure_date >$_POST[‘ARRIVAL'] And b.arrival_date <
$_POST[‘DEPART'];

2.Left join this with the room table and pull out rows with no match

SELECT a.room_number, b.room_number
FROM room AS a LEFT JOIN temptable AS b ON a.room_number=b.room_number
WHERE b.room_number IS NULL;

3.Delete temp table

I've tried doing this in Dreamweaver, but to no avail. I have a
feeling it is too complex for Dreamweaver.

My php knowledge is very basic and was wondering if anyone could give
me some pointers as how to do this in PHP?.

Dates In Range Falling Between Existing Dates
The latest quandry I have is that I need to:

a: check whether any dates in a date range entered by a client in a form (datefrom, dateto) conflict with any existing date ranges already in the database.

-this is a check to see whether the dates that a customer is trying to book are not already booked-
Obviously its easy to get the numbers out of the database (i.e. 28/12/2006 or whatever format) and from the form but how to I convert this 'range' actually into a range I can loop through that will return true if any of the dates are the same (i.e. already booked)?

b: is similar in that I want to check how many of the clients entered dates fall into the pre assigned high, mid and low season ranges in the database and multiply each of those days by the corresponding price.

I'm currently using

SELECT * FROM production WHERE date > &#55614;&#57159;-01-01' AND date < &#55614;&#57159;-01-04'

but that returns between the dates and doesn't include the the last date. Hopefully that makes sense to everyone. I'm using mysql 5.

$diff=$fromdatetime-$todatetime;echo "Diff = " $diff; echo "<br />";

changed like if $fromyear is 2007-01-01 & $toyear is 1997 -03-15

MYSQL, PHP And Dates
I need to create a system where listings can be entered into a database and show when they were listed, and an expiration date. I will need to compare those listings with the current date that they are viewed on also in order to decide whether or not a listing is expired or not. So, if when I store the listing, I format the date with:

Expiration_date = "$yyyy-$dd-$dd" and store it as "INT" in mysql,
store the date added using date("YmdHis") as "INT",
could I then run a search using something like:

SELECT * FROM $table WHERE DAYOFWEEK(exp_date) > DAYOFWEEK(NOW()) and MONTH(exp_date) > MONTH(NOW()) and YEAR(exp_date) > YEAR(NOW());

Please let me know what you think, I am sort of confused on this one. I am pretty sure that I will use php's timestamp, but will need to be able to compare it to that of mysql's NOW().
