how get reference in firebase

[Abdullah]

I am using firebase. I decided to have each users post under their uid, but somehow i cant make the reference and display it. I want to be able to display all data under every user uid.

//this is my reference now :         
var gettingPostRef = firebase.database().ref().child('Posts/');
//if i use this it gives only the current login user posts:
var gettingPostRef = firebase.database().ref().child('Posts/' + uid);

but i would like to have all data under all uid to be displayed may i know how to make this reference properly,thanks.
--- my code----firebase realtime-----

var gettingPostRef = firebase.database().ref().child('Posts');
gettingPostRef.on("child_added", function (znapshot) { // for getting all users posts
    root.child('users/').child(uid).once('value', function (userSnapshot) { //for getting users name
        var username = userSnapshot.child("Info/UserName").val().displayName;
        var gettingPost = znapshot.val();
        console.log(gettingPost)
        //checking for current users
        var arr = znapshot.val();
        var arr2 = Object.keys(arr);
        console.log("arr:" + arr2);
        //getting the value from database
        var url = gettingPost.url;
        var caption = gettingPost.caption;
        var date = gettingPost.Date;
        var title = gettingPost.title;
        console.log('File available at', url);
    })
})

----this is my firebase structure----

function myfunctionfirst() { $(".postingContent").on("click", function () {
firebase.auth().onAuthStateChanged(function (user) {
        if (user) {
            // User is signed in.
            // select unique name for everytime when image uploaded 
            // Date.now() is function that give current timestamp 
            var name = "123" + Date.now();

            // make ref to your firebase storage and select images folder 
            var storageRef = firebase.storage().ref('/SocialPost/' + name);
            var uid = user.uid;

            // put file to firebase 
            var uploadTask = storageRef.put(selectedFile);

            // all working for progress bar that in html 
            // to indicate image uploading... report 
            uploadTask.on('state_changed', function (snapshot) {
                var progress =
                    (snapshot.bytesTransferred / snapshot.totalBytes) * 100;
                var uploader = document.getElementById('contentBar');
                uploader.value = progress;
                switch (snapshot.state) {
                    case firebase.storage.TaskState.PAUSED:
                        console.log('Upload is paused');
                        break;
                    case firebase.storage.TaskState.RUNNING:
                        console.log('Upload is running');
                        break;

                }
                document.getElementById('submit').setAttribute('disabled', 'true');

            }, function (error) {
                console.log(error);
            }, function () {
                //getting the time posted

                var d = new Date();
                var year = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
                var dd = d.getDate();
                var mm = d.getMonth();
                var month = year[mm];
                var yyyy = d.getFullYear();
                var today = month + " " + dd + ", " + yyyy
                /////
                var downloadURL = uploadTask.snapshot.downloadURL;
                firebase.database().ref('Posts/' + uid).push({
                    url: downloadURL,
                    title: $("#name").val(),
                    caption: $("#message").val(),
                    user: uid,
                    Date: today,
                });
                // get the uploaded image url back 
                uploadTask.snapshot.ref.getDownloadURL().then(
                    function (downloadURL) {

      document.getElementById('selected-images').src = downloadURL;
                    });
            });

        } else {
            // No user is signed in.
        }
    });
});
};

Hey @Abdullah

Can you elaborate a little? For example, what you are getting back right now? What does your log say? etc?
