Is it possible to send the data from an input box in html to the lua server?

I'm working on a similar case. I guess the only way is to use the form action to sent the data to a URL.

I've got a form like this:

Code: Select all<form action="wifi.pht">
  SSID : <input type="text" name="APSSID" value="your ssid">
  PW   : <input type="text" name="APPASS" value="your password">
  <input type="submit" value="Set new SSID/PW">
</form>

When the button is clicked the browser is pointed to URL:

Code: Select allhttp://192.168.0.27/wifi.pht?APSSID=your+ssid&APPASS=your+password


On this page you need:
1. access to the full URL ( like $_GET in PHP)
2. some Lua code to to retrieve the parameter from the URL
3. some code to use the parameter for your own purpose.

For 1. I see no other option than change the webservercode. I declared a global variable (_GET) and copy the full URL request to it. Then it will be available for some embedded Lua script in the .PHT file of the page.

Am open for a more simple approach, anybody

Let us know when you have any progress.

With the version of the webserver I have there is no problem with using a form and the get method.
If i use a form like this:

Code: Select all<form method="GET"><br><input type="text" name="data" value=Peter>
Number<input type="text" name="number" value=17><input type="submit" value="Get"></form>


I get the variable in the reqdata table

Code: Select all<?lua for k,v in pairs(reqdata) do print (k,v) end ?>

Now if you look at the link from 4 dec by adamip, you will see a different implementation with post and log.file, so I think we are working with different versions ?

Sure here you go.
I realy think we need some kind of version numbering
