sql - Single or multiple mysql rows? (shopping basket) -

-

I am currently creating a custom e-commerce site (in php, but this is not really relevant for this question is).

I just got to make a shopping cart, and can not decide between the following 2 options:

Option 1:
Basket table:

  • Users
  • Items

    • In this option, I have a line per user, in all items with Archived items and quantity of

    This format is already used in a cookie based basket for non-logged users, so there is no problem parsing the item field.

    Option 2:
    Basket_items table:

    • id
    • user
    • Item
    • Quantity

    In this option, I will have one line per line in the basket.

    Option 3:
    > Suggest a better idea.

    Conclusions

    Both of my options are equally easy to apply, so the question comes below which the basket is more efficient to update / Will be convenient.

    Thanks for any answers, nico

    option 2 is the way to go To store all the objects and quantities in the field of objects (option 1) means that you are going against the relational nature of MySQL. You have to define a format and it will have to be parsed with option 1, along with the option you have not written any additional code. In addition, with Option 2, you will be able to easily do other things in line with the line, such as total calculation, shipping amounts, etc. along with reporting on item quantity sold (just a simple question).

    Of course, if I was writing this, then I would ask myself if there is a library available - such a general functionality in the shopping cart is not again to the PHP world. , So I do not know what the options are, but I'm sure there should be something that you can reuse. So finally, I encourage you to choose Option 3 - If you avoid it, do not apply it yourself: -)

    c# - How to capture HTTP packet with SharpPcap -

    -
    I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

    jquery - SimpleModal Confirm fails to submit form -

    -
    I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
