How can I get value in config_override.php via js

I don't think this is possible out of the box (although I have a workaround below) for security reasons. The values in config/config_override include stuff like database connection details, which you might not even want your highest privileged application users (i.e. Administrators) to know. The way I'd implement this is by creating a custom endpoint:

http://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_7.6/API/Web_Services/Extending_Web_Servi…

The main change I'd make to the endpoint api in the example is:

 public function MyGetMethod($api, $args){
  global $sugarconfig;
  return $sugarconfig['custom_value'];
  }

You could then get the value using the loadData function in your controller like this:

loadData: function () {
        var _this = this;
        App.api.call('GET', App.api.buildURL('name_of_your_endpoint', null, null, ''), null, {
            success: function (custom_value) {
                _this.custom_value = custom_value;
                _this.render();
            }}
        );
    },

Let me know if you have any trouble with this method.

Hi Autchara Chaiprom,

You can also use in the config_override.php the following:

$sugar_config['additional_js_config']['custom_parameter'] = 'custom_value';

After, you will be able to access the 'custom_parameter' with the following js code:

App.config.custom_parameter

When you initialize the js class you can also use:

initialize: function(options) {
        this._super('initialize', [options]);
        this.custom_value = App.config.custom_value;
}

Hope this helps too.

Autchara Chaiprom This is a much better solution than my own, mark this as the correct solution.

There may be times when you want to get the config.php values or you can't change config_override, but 95% go for Jorge's solution.    

Thank you both very much. Its work.

in config_override.php

$sugar_config['additional_js_config']['custom_parameter'] = 'custom_value';

In js controller

initialize: function(options) {  
        this._super('initialize', [options]);  
        this.custom_value = App.config.custom_parameter;  
} 

and I found that it not change value immediately when we change in config_override until we repair and rebuild.

Is there solution for change value immediately, no need repair and rebuild ?

From what I was able to see in the source code, those 'additional_js_config' only become available in the JS when you perform Quick Repair & Rebuild or when you clean the cache directory.

Thank you for explain, I got it.
