PHP SHoppiing cart without Database

Hi,

This can be done simply by using:
(A) Shopping Process:
1. Session (say, in PHP it will be $_SESSION) variable to keep the information (of user/products/cart)
2. Using text file to store user specifi events & upon successful completion of the process (i.e. user decides & send the order via email/fax) those text files can either be saved for future reference or upon a spefic period of time...can be deleted to save space

(B) Coming to the 2nd part i.e. email->fax, here you have to use some service providers like:
http://www.efax.com/
http://www.faxaway.com/about.shtml#internet_fax

[There are many more...just use Google]

As it stands...ideally you should use a scripting language like PHP/ASP/JSP to help you work with user activity (e.g. selecting & adding a product to his/her cart & moving on....& then finally placing the order...whereby sending an email...which in turn sends the fax).

So, by this process you will be able to eliminate the requirement of the Database for the time being...but if you really look for a robust structure, you should be looking forward to store user information in the Database when an user submits an order. Yes, you will collect that info & it will be sent to you via email->fax. But, what happens the 2nd time the same user comes bak to your site (which I am sure you will love to have...repeat business)? Coz. as per this structure...your user will again have to fill in all the information & then submit (to some extent this can be narrowed down by using cookies..but I will suggest using an economical DB like MySQL).

Hope this helps.

http://ph.php.net/session
http://ph.php.net/function.mail

you can use session in storing the data before sending it via email.
you can also mail() in sending an email.

additional hint:
//this means that the client others 2 boxes of pizza 1
$pizza1 = $_SESSION['Pizza1'] = 2;
$pizza2 = $_SESSION['Pizza2']   = 0;

$message ='Pizza 1 =' $pizza1. 'and Pizza 2 ='. $pizza2;
mail("oder@pizza.com", "Order Pizza",$message);

Just out of curiosity, how do you plan on avoiding abuse of this site without any login function or any user validation of some kind? If just anyone can go to this site and order a pizza how will the resteraunt know the legitimate orders from the fakes?


Alan

Dear Alan
You are right but the money which i will get from myclient won't be enough tomake site with database.if he wont cheap service then he will not get database andd if he need database then he must pay more.

So resturant or my client will get order my email and then they will phone him and confirm order.

I assume Amir plans to validate every order by confirming over the phone...then only delivering.
Else...if someone is paying (after placing an order)...no harm in delivering I guess. ;)

WC

all what is that i don't need database support bcz my client won't pay more for database support of the site. And the simple way is all Order or Details must send my email

Ok, I see. Thanks for the info. The reason I asked is I have written a similar system for some local resteraunts and I made it account based with logins because of the fear of abuse and fake orders and I was wondering if you had found a way around it that I didnt think of.

You are correct though, if the client doesn't want to pay for a "proper" site, then he gets what he pat he pays for.

BTW maybe you would consider awarding 500 points for that effort, huh?
JP

While I agree that you have made a nice effrot, Begging for points is very unbecoming. Have some pride man!


Alan

woops second last line should read

print("Address: <textarea name=addr rows=5 cols=40></textarea><br>");

'Maybe you would like to give me some points as well Alan ;-)
Dignity? Bah!

You can have all my points, they are menaingless. If I could trade them in for a toaster oven or t-shirt or something that would be one thing. I am here stricly for the feeling I get when I help someone fix a problem. <;o)


Alan

Cool down guys. Let us ensure that a problem gets a proper solution. As long as the purpose is served...what teh heck with points. :D

Regards
WC

PS: Jdpipe...cool snippet. Loved it...didn't try that though ;)

Hey WC no worries it's cool. I just write that code then only afterwards realised I'd gone to all that effort for so few points, I thought wow that's so far beyond the call of. Blush.
JP

Not sure who needs to "cool down" but I hope my comments where not taken as inflamatory. They where not menat to be. I was just suggesting that we as experts offering answers shouldn't be asking for points as it makes us look like we are here begging for points. It was said in jest and menat to be 'humorous'. I apologize if it was taken wrong.


Alan

Hi there, just to add my 2c worth, or 2p worth in my case, although your client doesn't wish to pay more money for the use of a database and login system, it might be worth explaining to him fully why using such a system would be adventageous.  Such as the easily additional of new toppings, or changing prices of different pizzas, not to mention the security and order tracking and statistics and so on.  At least then you've done your part and informed him of how it could be and that security and fake orders might cause him problems if he uses the system this way.

Obviously you've probably already told him this, in which case I'm sorry for mentioning it again :)

It might also be an idea to use a CSV file format with the different pizza's and toppings in, at least then it's a bit easier for him to change prices and add new items.

Cheers

Hi bimal Linux

I have tryed quick.Cart but i don't know how to use same programming concepts with my existing site

http://www.royalpizzaonline.de/shop/chines.php
http://www.royalpizzaonline.de/shop/Indien.php

please let me know if youhave some idea

regards
amir

hi  jdpipe

So i have seen your code it#s work fine but i ghave no idea how i can fix your code toworks with my existing webpage.

http://www.royalpizzaonline.de/shop/chines.php
http://www.royalpizzaonline.de/shop/Indien.php

thanx

Hi Amir

I'm afraid I can give you much more than I've already given. The array '$db' defines the list of products along with their descriptions, prices, categories. The array '$dbcat' defines the categories which you will display. You can add extra HTML at the top and bottom of the file I gave you to improve the layout of the page.

Hope that helps
