How to Show Which Question a User Is on When Taking My Quiz

How to display a Yes/No dialog box on Android?

AlertDialog.Builder really isn't that hard to use. It's a bit intimidating at first for sure, but once you've used it a bit it's both simple and powerful. I know you've said you know how to use it, but here's just a simple example anyway:

DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
switch (which){
case DialogInterface.BUTTON_POSITIVE:
//Yes button clicked

case DialogInterface.BUTTON_NEGATIVE:
//No button clicked

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage("Are you sure?").setPositiveButton("Yes", dialogClickListener)
.setNegativeButton("No", dialogClickListener).show();

You can also reuse that DialogInterface.OnClickListener if you have other yes/no boxes that should do the same thing.

If you're creating the Dialog from within a View.OnClickListener, you can use view.getContext() to get the Context. Alternatively you can use yourFragmentName.getActivity().

How to create a dialog with “Ok” and “Cancel” options

You're probably looking for confirm(), which displays a prompt and returns true or false based on what the user decided:

if (confirm('Are you sure you want to save this thing into the database?')) {  // Save it!  console.log('Thing was saved to the database.');} else {  // Do nothing!  console.log('Thing was not saved to the database.');}

Property [title] does not exist on this collection instance

When you're using get() you get a collection. In this case you need to iterate over it to get properties:

@foreach ($collection as $object)
{{ $object->title }}

Or you could just get one of objects by it's index:

{{ $collection[0]->title }}

Or get first object from collection:

{{ $collection->first() }}

When you're using find() or first() you get an object, so you can get properties with simple:

{{ $object->title }}

Check if PHP session has already started

Recommended way for versions of PHP >= 5.4.0 , PHP 7, PHP 8

if (session_status() === PHP_SESSION_NONE) {


For versions of PHP < 5.4.0

if(session_id() == '') {
