Forgot these:

String getCurrentInputValues(){
  values[“numberValue1”] = input1;
  values[“numberValue1A”] = input1A;
  values[“numberValue1B”] = input1B;
  values[“numberValue1C”] = input1C;  
  values[“numberValue2”] = input2;
  values[“numberValue2A”] = input2A;
  values[“numberValue2B”] = input2B;
  values[“numberValue2C”] = input2C;
  values[“numberValue3”] = input3;
  values[“numberValue3A”] = input3A;
  values[“numberValue3B”] = input3B;
  values[“numberValue3C”] = input3C;
  values[“numberValue4”] = input4;
  values[“numberValue4A”] = input4A;
  values[“numberValue4B”] = input4B;
  values[“numberValue4C”] = input4C;
  values[“numberValue5”] = input5;
  values[“numberValue5A”] = input5A;
  values[“numberValue5B”] = input5B;
  values[“numberValue5C”] = input5C;

Hi.
Take a look at “arrays” with Arduino. You can save your values in arrays and then, loop through them.
This is just the basic definition: https://www.arduino.cc/en/reference/array
And here’s a basic example: https://docs.arduino.cc/built-in-examples/control-structures/Arrays
This is just the starting point, then, you should be able to search for more information if you want to apply it to your specific project.
I hope this helps.

Many thanks Sara, will look into it.

Also, you should look into structs

Thanks Steve, A new command for me, will see if I can relate it to my problem. many thanks.

Once you understand structs and arrays, then you can think about arrays of structs. Basically each item, in your case an “input”, would be one struct with all of the properties that you want to keep in it. Adding another item would only require adding a new struct rather than having to declare all of the properties over again. If you need another property it’s just a simple matter of adding it to the struct definition.

Perhaps an example:
 

struct input {

  String request; // Parameter in HTTP POST request HTML form
  String formValue; //Variable to save value from HTML form to search for
  String path; // File path to save input value permanently
  String value; // Current input value
  int pin; // Input pin
}

 
input input 1 = {“input1”, “”, “/input1.txt”, “”, 1};
etc
 
 

wow, I will try and follow your example, and digest it on a small scale. Many thanks Steve

Hi,
Have read a lot about struct & arrays and tried a simple program to try and understand, see below, but I have an error, “expected identifier before numeric constant” in it is on line 4   ‘struct tablet[2] {‘ I don’t know if I am on the right track, or if I need a Library ? please could you help. 
 
 
 
 
struct tablet[2] {
  String request;
  String formValue1;
  String formValue2;
  String formValue3;
  String path;
}
int i;
 
void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
 
}
 
void loop() {
  // put your main code here, to run repeatedly:
 
for (i=0; i<2; i++){
 
  Serial.print (tablet[i].request);
  Serial.print (tablet[i].formValue1);
  Serial.print (tablet[i].formValue2);
  Serial.print (tablet[i].formValue3);
  Serial.print (tablet[i].path);
 
 
delay(5000);
}

When you declare the struct you don’t use array notation. You use that only with the variables that you create. So take out the [2] after the struct name.

let’s see if I can explain it better. Think of a struct as declaring a blueprint for something, let’s say a drawer. It will have sides, a back, a front, a pull etc. each time you create a drawer it may have different lengths, widths etc. The blueprint has a name you give it and then you create instances of the blueprint. Each instance can be placed in an array.

Thanks Steve, removed [2],  and put it on the end with a variable array.
Also tested changing the values.
So I have been working with project 4.1 in the ESP32 Web server book and will go back to using only 2 input forms (instead of the 5 inputs I have got working) to see if I can change the way it works using Struct instead.
This code works OK  thanks to you.  many thanks
struct tablet_def {
  String request;
  String formValue1;
  String formValue2;
  String formValue3;
  String path;
} tablet_monitor[2];
int i;
 
 
 
void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
 
}
 
void loop() {
  // put your main code here, to run repeatedly:
 
for (i=0; i<2; i++){
  Serial.println (i);
  Serial.print (“request “); Serial.println (tablet_monitor[i].request);
  Serial.print (“formValue1 “);  Serial.println (tablet_monitor[i].formValue1);
  Serial.print (“formValue2 “); Serial.println(tablet_monitor[i].formValue2);
  Serial.print (“formValue3 “); Serial.println(tablet_monitor[i].formValue3);
  Serial.print (“path “); Serial.println (tablet_monitor[i].path);
 
  }
delay(5000);
 
tablet_monitor[0].request = “This  Request”;
 
tablet_monitor[1].path = “/input1.txt”;
}

Structs are a good intro to Object Oriented Programming. This is where everyone should be going.

Thank you all for this informative discussion.
I’ll close this issue now.

Sara

Thank you
