Customfields saved values not display on portal

[zstergios]

When I configure the settings are saved and everything works great, if I start the portal to change some settings, the last saved values are not display and default value is displayed.

The thrid parameter is default value. I expected to see the last saved value instead. Is it bug or I missing something?

#BEGIN
  WiFiManagerParameter custom_weburl("weburl", "Web URL","https://NAME.domain.com", 128, "placeholder=\"Web URL\"");
  wm.addParameter(&custom_weburl);

  wm.setSaveParamsCallback(saveParamCallback);
  wm.setMinimumSignalQuality(10);
  wm.setConfigPortalTimeout(180);
  //wm.setConfigPortalBlocking(true);
#END

you have to restore saved values, wm doesnt know what you saved

How to restore them?

This way causes restarts

String getParam(String name){
  //read parameter from server, for customhmtl input
  String value;
  if(wm.server->hasArg(name)) {
    value = wm.server->arg(name);
  }
  return value;
}

and that way returns empty value probably because it's before adding the "custom_weburl" to wm.addParameter

  const char* url =  custom_weburl.getValue();
  WiFiManagerParameter custom_weburl("weburl", "Web URL",url, 128, "placeholder=\"Web URL\"");

if(wm.server->hasArg(name)) { value = wm.server->arg(name); } return value; } there's a bug, since wm.server at that moment is equal to nullptr. then you cannot get the custom_field value.

What do you mean? Thats called in a callback whats the scope here?

you can just try to compile and run the Advanced samples, while using custom_field, if you want to get custom_field value, it will crash, since wm.server is equal to nullptr.

Still not sure what you are calling, this happens in the example with no changes?

while compile and running this sample https://github.com/tzapu/WiFiManager/blob/master/examples/Advanced/Advanced.ino

you will find that custom field value with name "customfieldid" cannot be get and store, at that moment calling wm.server, it's nullptr. you will never have a chance to use hasArg or arg to check and get the value.

But its only called from the callback is it not?
