Accessing $post in function scope


Accessing $post in function scope

it fixes the issue The other functions do not receive the $post you expect when the loop is inside your function. The $post variable only "exists" inside that function.
One simple way to solve it would be to just put your $post variable in the global scope:
code :
function get_grid(){
    global $post;
    $posts = get_field( 'featured_projects', 'user_'.get_post()->post_author );
    /* all the other code that works fine outside
       a function should work fine inside too now */
}

Accessing a function defined inside a function from the global scope?

fixed the issue. Will look into that further You cannot access a function context from the "outside world". Well, to be accorate you could do it in some older js engines which allowed for accessing .__parent__ attributes, but that is old'n'busted and no longer available.
However, you would need to either expose some functions within your closure, or you creating a namespace object where you write all of your logic in (which also has to be available in the parent context).
code :
(function( $ ) {
    function myFunc() {
        // do stuff
    }

    function anotherFunc() {
    }

    window.myFunc = myFunc; // expose myFunc globally
}( jQuery ));
var myNameSpace = { };
(function( $ ) {
    myNameSpace.myFunc = function() {
        // do stuff
    };
}( jQuery ));

// somewhere else
myNameSpace.myFunc();

this one helps. I'd suggest you use a third function to separate your logic
As for the propOne, you can see my comment in your question, just put var in front of it.
code :
execute();

function init(app) {
    app.DivNamingPushArray = getNamingArray();
}

function execute() {
    var app = {};

    //call the "init" function
    init(app);

    console.log(app.DivNamingPushArray);

}

function getNamingArray() {
    //our empty array for pushing
    var DivNamingPushArray = [];

    //object where we define our properties that will be used later
    var namingScheme = {
        "parentId": {
            "firstChild": "blah",
            "secondChild": "blahblah",
            "thirdChild": "blahblahblah"
        }
    }

    //loop through the namingScheme object and push into array
    for (var propOne in namingScheme) {
        DivNamingPushArray.push(propOne);
        for (var  propTwo in namingScheme[propOne]) {
            DivNamingPushArray.push(namingScheme[propOne][propTwo])
        }
    }

    return DivNamingPushArray;
}

jQuery function scope and accessing the function outside the scope

it helps some times The simple answer is to use the global scope with namespacing, this will allow you to use the object in different files as well.
code :
(function($, win) {

    win.MYTEST= {

       init: function() {
          alert('Hello World');
       }
       exec: function() {
            alert('function executed');
       }
    }

}(jQuery, window))
const MYTESTModule = (function($) {

    return MYTEST= {

       init: function() {
          alert('Hello World');
       },
       exec: function() {
            alert('function executed');
       }
    };

}(jQuery));

export default MYTESTModule;

it fixes the issue Well, its pretty easy. $http returns a promise. So use that nice addition to create you own promises.
What currently happens at your code is the following:
code :
accessScopeFunction();
foo();
function accessScopeFunction()
{
    var promise = $http(
        {
            method: 'POST',
            url: 'http://localhost/sjb/public/admin/groups/assing/angular/get/databasename'
        }
    ).then(
        function successCallback(response)
        {
            $scope.getDatabaseName = response.data.event_db;
            console.log($scope.getDatabaseName);
        },
        function errorCallback(response)
        {
            return 'Fault';
        }
    );

    // Return the promise
    return promise;
};
function foo()
{
    var promise = $http({
            method: 'POST',
            url: 'http://localhost/sjb/',
            data: {
                'databasename': $scope.getDatabaseName
            }
        }
    ).then(
        function successCallback(response)
        {

        }, function errorCallback(response)
        {

        }
    );

    return promise;
};
$scope.init = function (group_year_id, year)
{
    accessScopeFunction().then(
        function ()
        {
            foo();
        }
    );
};
foo().then(function () { ... })
