#70802 Hello all
Im writting a web setup file on my esp8266 using the NodeMCU.
I can send easily data to the web page but Im having problems getting data from the page.
Check the above below code:

"
...
buf = buf.."MQTT..User..:<input type=\"text\" name=\"Gmqttuser\"><br><br>"
buf = buf.."MQTT..Pass..:<input type=\"password\" name=\"Gmqttpass\"><br><br>"
buf = buf.."<a href=\"?pin=GO1\"><button>Save&Restart</button></a>&nbsp&nbsp&nbsp;<a href=\"?pin=GO2\"><button>Leave without SavingOFF</button></a></p>"
"
I´m able to get the data from the buttons from the ?pin but how can I get the value inside the text boxes???

Thanks
.Pedro

#70826 Thanks for the reply.
It works perfectly.
I leave Below the code of the TCP socket that gets values from the web browser and saves it in a file

local function HTTP_start()
srv=net.createServer(net.TCP)
srv:listen(80,function(conn)
conn:on("receive", function(client,request)
request= string.gsub(request,"%%21", "!")
request= string.gsub(request,"%%26", "&")

local t={} ; i=1
for str in string.gmatch(request, "([^"..":".."]+)") do
t[i] = str
i = i + 1
end

local y={} ; i=1
for str in string.gmatch(t[1], "([^".."=".."]+)") do
y[i] = str
i = i + 1
end

if (y[10] ~= nil ) then
y[2]= string.gsub(y[2],"%&Gssidpass", "")
y[3]= string.gsub(y[3],"%&Gip", "")
y[4]= string.gsub(y[4],"%&Gmask", "")
y[5]= string.gsub(y[5],"%&Ggateway", "")

if string.match(y[10], "Save&Restart") then
