So the State Key will be ID and it is going to be 'a.id' in Table Key, equals in 'Comparisons Operator'. It is this Filter Type that makes the item load. There are many ways to load items.

Please go and watch the tutorial on Dynamic Get on GitHub. There is a place, I just show you called Wiki. In the Wiki, there are links to all the different tutorials. You should really watch all of that. My encouragement is to really watch everything. I have often seen people ask the question [00:55:35](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h55m35s) in the issue area which is dealt with in the tutorials. I'm sorry we all have a lot of things to do and so if I don't answer these questions but simply point you to the tutorial I hope you understand.

### Two Dynamic Gets Created - Second Return One Greeting

We've got in the Dynamic Get all the value selected that we want and also how to limit it. The tweak is in place and the limiting factors. We don't need to join it to any other tables, we simply going to [00:56:09](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h56m09s) return these values. We could add the username values if we wanted. We wanted to show who created this. We could say created by, go to Joint, click on the Join Database Tables not Join View Tables because we want to use the user table and we want a single [00:56:46](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h56m46s) item returned and on Field it will be a.created_by and in the Joint Field it will be b.id and we want the username. We don't need the id, we already got that so just the user_name. We could just say [00:57:19](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h57m19s) greeted_by. He's the one sending the greeting. Save and close. Now we've got two Dynamic Gets, a Listgreeting, and a greeting. This is what you need to build first. Again starting at the Database looking at what is the data I want [00:57:54](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h57m54s) on the page?

The 'Username' is needed but not the ID, it is already there, so only the 'user_name' is necessary.

We want the Listgreetings and so this Listgreetings gives us a few Snippets. Do know that the Snippets are not always accurate because it's very difficult for me to always know exactly how the implementation is going to work out. I'm giving you a snippet which is how I expect you to use the data. You can adjust that and this is where your knowledge of PHP will [01:02:10](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h02m10s) come into play. You should know what this and that little arrow items is because we are working with an object. You must know what it means? How to use an object? How to interact with an object? How to parse over it? How to grab its values? How to update its values? All this is part of your own background that you need to bring to JCB. JCB is not going to crank out customized Site Views the way it does the Admin Views. My idea was when it comes to Site Views I always want to do something different and I just want to have the ease of getting all the data on the page and then be creative. I haven't spent much time to make this as automatic, I want to set up of the back end and the Admin Views because this is what makes your component different from every other [01:03:15](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h03m15s) Component out there. We want to encourage you to do you do a lot of preparation and thinking about Data Structures in relationships because your Dynamic Get can grab from so many data places and bring all that data to you in a nice object which you can then parse and display with a lot of permission switches as I will show you in a moment. That is giving you a little backdrop on why the Dynamic Get and the Site View even the Custom Admin View, it's relationship and why it is like that.

Basically looping through those items is this these two strings and is all we need. I could grab a list view(select a snippet). We are busy working on adding the Bootstrap Library to JCB. At the moment we got UIkit version 2 linked to JCB. And I've selected the list option for this Uikit. Uikit is a library developed by YOOtheme. If you do not know UiKit I would encourage you to go Google that and then [01:04:46](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h04m46s) you'll see it's quite a nice library to use. We have voted that Bootstrap is the better one and so we are migrating to Bootstrap. We will still support UiKit as much as we can. We are going to loop over the items. Show the name. Nothing is yet clickable, nothing is editable. It is to get you introduced to using Site Views. Save and close.

Now we going to go back to our Component and we are going to add the Site View to it. You might ask why don't we just add the Component to the Site View when we create the Site View? That was an idea that I did play with. But because of Database relationships and all kinds of reasons I felt that the better approach would be to link Site Views at the Component area instead of at the Site area. This gives us the option to use Site Views quite easily within other Components. That was really the idea behind it We might rethink this and we might reshuffle this in the future. I mean this is the first time I build such a Component called JCB. Who knows what happens if we start refactoring it in a more Advancement program is get involved. It might become even far better than it is now. [01:06:20](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h06m20s) This is how it works at the moment.

You can't change the type because the Type up at the top of the page needs to correspond with the type in the XML. Changing the type in the XML will not work.

We don't need any of these other fields, so we can just remove them. We don't want the filter to be set to raw. We would rather use the word string. Since we don't want any HTML at this stage in our greetings. If you want HTML now in the greeting you can use the Save HTML. I see it's not in this list but it does exist.

If we go without installing we go to the Component you will see that it hasn't updated the view because this was open. Before doing anything I would suggest reopening the view, refresh the page. So that the changes will show.

But we did add a new text field. If we go to the Compiler and we compile the Component, you will see that it dynamically incremented the version 2_0_1. If we go without installing we go to the Component you will see that it hasn't updated the view because this was open. Before doing anything I would suggest reopening the view, refresh the page. So that the changes will show.
### Install The New Changes

We can go back and install the new changes. If we go to a Hello World we should be able to open the Hello World and we should see the Alias there and if we click save, it should dynamically add a new Alias. We'll have to do this for every item, because the Aliases are saved or created only once you saved the item. I'm just opening all of them quickly. Usually a user using your Component, you only going to ship this Component when you've got everything in place. They wouldn't have to do all this gymnastics to make sure that all the values are in place. If by some reason you will have to help them along with some Custom Scripting. [01:19:58](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h19m58s) Now that we got all our items set and it has an Alias, we can start working on those links.

We can check whether this alias is being brought to the page by adding a php.var_dump.

We can look and see there's the Alias and it created that slug we spoke about. We got the slug for every item and that is the first step in setting up a well-form link for opening one of these items.

I can tell you if you want to build Components for Joomla and you want to go outside of the box and build things that are unique and completely different from what other people are doing and this is really just the basics.

### Use PHP For Creating A Link

We going to setup a href here around this name. But we are going to use php to take care of creating a link for us. Here we are simply going to say php echo. I'm going to go and show you where we get the class name for what we want to do here. Back in the code you will see that there is in the helpers class a [01:23:11](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h23m11s) file called route.php. You can open that and you'll see that you have what is now called Hello_worldHelperRoute. If you scroll down, we don't have this stage have. Oh yes we haven't added the the site view for the single record. So there are some values missing here. I should have first done that. I'll go do that now, but we'll come back to this file. There is another file or I should say class that works together with this class .[01:23:48](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h23m48s) It's these two classes with their methods that we were going to use to build our link.

### Create Site View For The Single Record

Let's create that display Site View. So I've removed the var_dump from this view. I'm going to save and close this. I could have set save a new. I'm going to create another Site View. We are going to call this Greet. We can't call it greeting because like we said there is already a greeting in the front. Or Greeted that one might be better. We going to make a nice display here. I'm using [01:24:40](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h24m40s) Panel. I'm going to copy the Panel Snippet and paste it in Default View. The title I'm going to make the name. The content will be the greeting. Now I don't want two of those, so I'm going to take out this one.

But he will basically view one Greeting. It will also show you who setup the greeting. We can close this. We got this Greeted Site View. We can go to the Admin area [01:25:36](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h25m36s) of the Joomla Component area. I'm going to click on Edit. And actually add a Site View to the Component. Same way we did before. Can I say I want Greeted. I don't want it to have an Add Menu. It must have Has Metadata. [01:25:59](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h25m59s) It's not a Default View. I also want Access there. By Default it's not Public. Save and close. We'll Compile the Component again. I've compiled and install it.
