I have been struggling with a sketch for days now, and have finally achieved something very close to my goal.
Here is what I have working, and the ")<---" in the CODE will show where I was able to get things working, and what lines I entered.
ATTN: This WORKS. Will NOT FAIL due to /html tag, though I don't understand why. No complaints. Just curious.
CODE:
// Command for server GET and POST request.
void serverCmd(WebServer &server, WebServer::ConnectionType type, char *url_tail, bool tail_complete)
{
int chk;
float t = dht.readTemperature(); )<------ THIS block of 3 lines.
float h = dht.readHumidity();
if (type == WebServer::POST)
{
bool repeat;
char name[20], value[16];
do
{
repeat = server.readPOSTparam( name, 20, value, 16);
if (strcmp( name, "On" ) == 0)
{
setLatchChannelOn( atoi(value) );
}
if (strcmp( name, "Off" ) == 0)
{
setLatchChannelOff( atoi(value) );
}
if (strcmp( name, "AllOff" ) == 0)
{
sendRawValueToLatch1(0);
sendRawValueToLatch2(0);
}
} while (repeat);
server.httpSeeOther(PREFIX);
return;
}
server.httpSuccess();
if (type == WebServer::GET)
{
P(message) =
"<html>"
"<head>"
"<meta http-equiv=\"refresh\" content=\"5\">" )<-----THIS line
"<title>"
"PAGE"
"</title>"
"</head>"
"<body>"
"<H1 style='font-family:hobo std;'> PAGE</H1>"
"<form action='/page' method='POST'>"
"<p><button name='AllOff' value='0'>All Off</button></p>"

}
The only thing I have left to figure out is how to get the T/H figures to print ABOVE the relay buttons, rather than below, but when I move the lines of code that pertain to the T/H data, it makes my buttons disappear, or the Buttons/Title disappear depending on where I place the code. Which is somewhat confusing.
Maybe someone can help with that part?
Thank you,
Darren
