nested sets - What does node mean in MySQL? -

-

Can anyone explain the meaning of nodes in MySQL?

This is talking about a nested set.

I am reading a document from Codeigniter's wiki and I'm not sure what to include in my $ node. GetSubTreeAsHTML (line 704) presents the field for each node Return to the given node *: GetSubTreeAsHTML (array $ node, [array $ field = Array ()]) * array $ node: * node to start from array $ field: node to display for each field

You are part of the code you are looking at. Full code of the function.

In this case the "node" refers to the data node. Nested sets are good because they allow you to select a whole branch of hierarchy with only the start node.

It seems that the function specifies that a tree part of HTML starts with the node you specify. The backendpro interface has to give hierarchical data somewhere.

Edit : The nested set not is a MySQL-concept, but there is a good article about Nested and MySQL here:

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...

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option. However, when I select a new value and I save ...

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...
