Country/State Dropdown in CakePHP -

-

How do I deal with the combo box in the ideas with the form assistant? For example:

Select the country box (Selecting the country will filter the selected country states) Select the States box

This will be with the help of JavaScript / Junkies etc. I came to an example with the main AJAX assistant of cake, but it would be great if someone could help in javascript example.

Thanks

thoughts / edit.ctp 

  & lt; Script type = "text / javascript" & gt; $ (Document) .ready (function () {$ ('# country'). Change (function () {$ ('# state'). Load ('/ controller / getstates /' + $ (this) .val ( ));});}); & Lt; / Script & gt; & Lt; Select ID = "Country" name = "country" & gt; & Lt; Option value = "1" & gt; Greece & lt; / Options & gt; & Lt; / Select & gt; & Lt; Span id = "state" & gt; & Lt; Select name = "state" & gt; & Lt; Option value = "" & gt; & Lt; / Options & gt; & Lt; / Select & gt; & Lt; / Span & gt;

and the controller.php 

  function getStates (int countryID) {$ this- & gt; Set ('selectbox', $ this-> state - & gt; address ('list', array ('conditions' = & gt;' state.ountry_id = '. $ Country id,' field; = & gt; ; Array ('description'));}

and thoughts / getstates.ctp 

  & lt; select name = "state" & gt; ; & Lt; Option value = "" & gt; & lt; / option & gt; & lt; php foreach $ option as option $) echo '& lt; Option value = "'. $ Option [' id ']." & Gt; '. $ Option ['description']. ' & Lt; / Options & gt; I hope I can not forget anything

-
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.
