How to write to {global:myfield}

Hi Max

let me know why {global:local}  or {globals:local} show me the current value "1" in   html-box

and  in php-box  echo $this->global['local']; or echo $this->globals['local'];  doesn't show anything

kind regards

sorry I already realized of my mistake echo $this->globals('local');    with round brackets ;-)

Hi Max when Try to update global variable from my form I get this error

$this->globals('local')=2;

Hi teldrive

It's not possible to update the variables in the globals, you need to create a form variable and update it if you need:

$this->set("local", $this->globals("var"));

$this->get("local"); // this is how you get it now

$this->set("local", "new"); // now you can change it

Hi Max

I must be missing something, I tried all this but I couldn't change the global variable from "1" to "2"

$this->set("local", $this->globals("local"));

$this->data['local']=$this->get("local");

echo $this->data['local'];

$this->set("local", "2");

echo "first attempt ".$this->globals("local");

$this->set( $this->globals("local"),"2");

echo "second attempt ".$this->globals("local");

$this->data['local']=2;

$this->set( $this->globals("local"),$this->data['local']);

echo "third attempt ".$this->globals("local");

thanks in advance

The global variable can NOT be changed, you can only get it and use it 😉

Ok , understood then you have to change the concept "global variable" by "global constant"😊

by the way should be very interesting to change it in order to avoid to create a table to make easier programming

Yes, that would fit better 😊

But why did you need to change the global variable ? why not use a local variable ?

I have an web-app to change plates database for an ANPR system, by default (for security reasons) web app only work with private IP address

If I need to test a new feature  remotely I change global variable to use IP public(only for administrator)  in a settings web page. Of course I can use settings table to do it, but I was exploring the possibility to use global variable to do it ;-)

I think you can do this with a local variable at the form itself, but I can not imagine it well to try it

Wehen I try : 

$this->set("local", $this->globals("var"));

I get an error : Call to undefined method G3\A\E\Chronoforms\L\Page::globals()
