Hi guys, i have a bit of a long one. I’m trying to combine a code from randomnerdtutorials to another one i highly modified from them as well. The thing is, they both use different way to create the HTML web page. The one for the relays creates the page directly from the main.cpp file where the one I’m working on uses an external file (index.html) and publishes it via SPIFFS.
So what I’m trying to do is insert the portion of the main.cpp file used to create multiple HTML button:
String processor(const String& var){
//Serial.println(var);
if(var == "BUTTONPLACEHOLDER"){
String buttons ="";
for(int i=1; i<=NUM_RELAYS; i++){
String relayStateValue = relayState(i);
buttons+= "<h4>Relay #" + String(i) + " - GPIO " + relayGPIOs[i-1] + "</h4><label class=\"switch\"><input type=\"checkbox\" onchange=\"toggleCheckbox(this)\" id=\"" + String(i) + "\" "+ relayStateValue +"><span class=\"slider\"></span></label>";
}
return buttons;
}
return String();
}
Into my own button that bypasses the %BUTTONPLACEHOLDER%:
<label class="button1">
<input type="checkbox" onchange="changeState(); toggleCheckbox(this);" id="1">
<span class="button" id="button1" style="color: #4CAF50">Pull</span>
</label>
I only have one relay and the thing that’s bugging me is when they create the button, they put
id="" + String(i) + "" “+ relayStateValue +”>
Where they get the relayStateValue from the main.cpp:
String relayState(int numRelay){
if(RELAY_NO){
if(digitalRead(relayGPIOs[numRelay-1])){
return "";
}
else {
return "checked";
}
}
else {
if(digitalRead(relayGPIOs[numRelay-1])){
return "checked";
}
else {
return "";
}
}
return "";
}
I really have no clue what to do, i dont know if it would help to provide the whole code, if so i can dot that.
