The JavaScript I'm using is this `uikitFileUploader` custom code. Let's look at that first. We can search for it and open 'uikitFileUploader'. This is the code that gets added have a little bit of PHP, and it is saying `[[[arg0]]]_formats'`. We are asking getting the global parameters of the formats we set. Remember it is set in the global settings. We are saying that `document` is the first parameter that is passed.

Here we have `[[[arg2]]]` and `[[[arg1]]]` `progressbar`. If you think about the id, it says `progressbar` which is the third argument that is `main`.

It is targeting it here saying that is the `progressbar` we are going to use.

That is the reusable snippet. This same snippet uikitFileUploader is reused for various areas. If we were to close, and open the Media Note, It may be seen that it is really just using the same snippet. If you go to Script, you will see it is the same snippet.

Where the other one was saying `document-documents-main`. The same applies to the image. With the image there is also that kind of behavior. It says uikitImageUploader, this one is not using the FileUploader, it is using the ImageUploader which is a little different.

I will also paste this out for you to look at. Always remember these arguments behaves the same as an array which means that the first argument will always be 0, the second argument 1, and so forth. I'm using arguments in this snippet. Everywhere where I declare it, I am passing the three arguments that are required, use this `+` to pass it.

You need to figure that one out if you want people to download your documents. If it is just to upload images of course you do not need any of this. But it is only when you are going to have a downloadable file or media.

### Server Side Of Implementation

Now let's go look at the server side of this implementation. The server side is in the documents Admin View. On opening the PHP tab, we have this Ajax area. Like I showed before you need to set up the Ajax where this area targets the controller. In the controller it creates all these necessary script [00:51:54](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h51m54s) to make this method. We are going to look at the inside of that custom code to make this method available to the Ajax call. There are some values that we set because every component I use this stuff in is different, so for some we are using `images`, `documents` and `media` as the types and for some targets the `main` and `doc`.[00:52:23](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h52m23s) Regarding the `allowedView`; there is only one view in this component that is allowed to use in the Uploader and that is the document view. The `getViewID` is the function which I get the actual view name and ID. It is using the session to throw that around to insure that nobody is able to tamper with that value through the front. So that is just extra gymnastics to add another layer.
Now let's go look at the server-side of this implementation. The server side is in the documents Admin View. On opening the PHP tab, we have this Ajax area. Like I showed before you need to set up the Ajax where this area targets the controller. In the controller, it creates all these necessary script [00:51:54](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h51m54s) to make this method.

### phpAjaxUploader - Custom Code Area

We are going to look at this `phpAjaxUploader` in the custom codes area. Let's Search for it in the custom code area. I am using custom code because I am reusing it. At the moment it does not look like I am reusing it in many places, it only says it is used in component. This is not the area where I am doing my work, this is just for tutorials. I am using a different Joomla website than this one. This one is only for demonstration. I am reusing this code in many components and we have `image` formats that are allowed in the system, `Document` formats that are allowed in the system and `Media` formats that are allowed in the system.[00:53:57](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h53m57s) You can adapt this to allow whatever you like. This is the available formats. Remember in the options area of our component, it has a media area and there we have allowed documents, allowed media formats, and allowed image formats. These should be the same. It should be the same list, having the same values. But these are a field we created in Joomla, a List field. This is manually added to the components configuration area.

### Quick Demonstration How add A List Field To The Components Configuration Area

If you don't know what that is, let me quickly show you. In the component it has this component config. If your component doesn't show one like this, Hello World, it doesn't show a component config, you can go into the component and then in [00:55:16](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h55m16s) settings there is this button '_Create component config for this Joomla component_'. Close, I do not want to do Hello World, I can show you with the Document Manager. We could use the same button in Settings. We can edit it if it has not have one, you can create one. You select fields with their custom values and the tabs in which they should be displayed.[00:55:50](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h55m50s) I have selected 'Allowed Document Formats(list)', which is just a list of the formats and I set it to allow multiple selection. That is how this Allowed Media, Allowed Image, and Allowed Documents are done. Then there is the crop document image. If you do not know how to create a field, and how to set radio buttons, or list, then go review the videos about that. That is how we deal with that and that list we have looked at now is the same list as what we see here. [00:56:29](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h56m29s) It should be the same because this is the allowed, and that list shows the user what is allowed for the system. [00:57:03](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h57m03s) This is what you could say is available formats, and then those drop-downs is what you as the owner of this website, where this application will run, will allow. This list should be the same as the one there, but it also is going to be used if people post a specific type, as if it is allowed. We are going to be able to bounce this and make sure that security wise we are safe.

This is where the hidden field name, remember I said to you there's some convention in the hidden field name. Well, this is where that convention comes into play. The hidden field name is build up from 'target' and 'targetType'. If these two are not correct we are not going to save this value at all. We are building an object which we will take, since we have validated that this is definitely the allowed view, and this object and ID, then we update the database. We're done. [01:09:13](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h09m13s) We have the 'fileName' and we are going to pass the 'fileName' here in the same way, and return to the browser. That's the service side of this implementation. There are some things which I haven't explained. Like [01:09:33](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h09m33s) this resizing of the image. I didn't give much explanation. 'GetFolderPath' you don't need to write that all up. You could make this work without knowing those things. [01:09:48](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h09m48s) You could put a hardcoded path here as the filePath.

Then I fix it everywhere for every place it's been used. There is sometimes the need for decoupling some of these functions in some, but I'm trying to do as much as I can to not to that.

### SetFileNameArray - Another Function

'setFileNameArray' is another function that you saw in the upload where is it 'setFileNameArray'. This 'setFileNameArray' is key when you realize that the actual file already exists because the ID is there. That means that there are other files possibly still already in the database. With the add and basic view, we trigger the 'setFileNameArray' function to check the database [01:11:16](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h11m16s) for that specific target field, get the values, encrypt them, load new values to that and then pass it back to us. Where if the item doesn't exist, that means it doesn't have an ID, I don't know if you remember when we [01:11:35](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h11m35s) did some demonstration, I was adding multiple media files that only one ended up being remembered, that is sort of the downside of the current implementation. If the ID doesn't exist, we're not able to keep track of that. [01:11:55](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h11m55s) It's only when the ID exists, that we are able to do multiple uploads at once.

### Heads Up - Once Saved The Item - Ready To Allow Multiple
[01:12:03](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h12m03s)
I should give a little bit heads up about that. Once you have saved the item, you're ready to expand upon it and to allow multiple upload at once. The 'setFileNameArray' is dealing when you are having multiple. You'll see there are image and document. When the file I'm using is plural, it tells me that it should allow multiple. [01:12:32](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h12m32s) If it's singular, image and document, then I don't allow multiple. I'm just going to remove the old one, and add the new, done. When it is plural, we are using the 'setFileNameArray', and we are building it to be multiple.

### 'removeFile' - Some Point Do Validation

One thing I didn't emphasize here, is that we remove the files as well. There is a 'removeFile'. It also at some point does a validation to check whether the user has the permission to remove files. It will remove the file. It's also uses [01:13:23](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h13m23s) this 'setFileNameArray', but then it passes the remove variable to it. Which then means the action is not to add but to take away. You will see the action and the Add and the takeaway option. It behaves a little bit different. [01:13:41](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h13m41s) We still get back the array, we still build an object, and we still updated the database, as well as removing the file. All of this code I will dump on GitHub and the gits for you to reuse as you see fit. you'll obviously have to Adapt it And Keep it under an open-source license. That's the only requirement. [01:14:14](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h14m14s) That if all those things line-up and are in place, going back to our Admin View. 'CUSTOMCODE=phpAjaxUploader' needs to be there. These things need to be here(see video). You could pause the video [01:14:31](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h14m31s) and make sure that you have the same kind of Ajax query calls option. Here I am doing some opening of the files. You will see that I'm building what I have called 'links'. It is going a little beyond showing you a little bit of my implementation and these links eventually end up on the page. We've go back to our JavaScript, and scroll down, we will see this 'getFiledJS'.

You will see that here I have 'load the links to the page' document links, and I'm adding it to a variable called 'documentLinks'. [01:15:37](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h15m37s) In the Custom script, 'getFileJS' you'll see if I'll take this copy and search, you'll see that I'm using that array and saying, is this property there? [01:16:03](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h16m03s) And then creating a link. That is how we deal with some of that. It works very well, to sort of pass value from JavaScript to PHP, and have it available there.
Let's again look at that '`getFileJS`'. You will see that those links come into play. You will see that here I have '`/load the links to the page`'` document links`, and I am adding it to a variable called, '`documentLinks`'.

I know this was a lot of [01:16:22](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h16m22s) things to take in, and I would expect you to realize that the previous implementation is much easier. But like you've seen when someone does create a document, and they are able to easily drag and drop stuff, it crops it and gives your component a much easier feel to it. [01:16:52](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h16m52s) Instead of the old you could still do the old select, but the drag and drop have become quite popular. This implementation is very nice to have. I'm sure from what I've shown you, you should be able to get this going in your component. [01:17:14](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h17m14s) I'm not going to give support on to this, meaning that if you get stuck, you are on your own. You will need to know your JavaScript, and your PHP, and you will need to know how to debug, and how to line-up these concepts that they all [01:17:36](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h17m36s) I work in synergy together. It's not going to be easy for me to do that, especially since I do not see the code. But if there isn't any of the code that I've share on Gits, which I will also put in the description below this video. Even if that code has issues in it, [01:17:57](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h17m57s) or errors that are a very big problem or something. Then please do feel free to give me a heads up over there. We'll collaborate and improve it as necessary. At the end of the day, this feature is way behind what [01:18:19](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h18m19s) you really need. There is a media manager in Joomla which is ideal. The advantage of this way is that your user is never going to interfere with other user documents or images or stuff. If you use this concept, they will not ever go to look on your server at a list and select stuff. This is why I think people would like this, [01:18:43](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h18m43s) because they can upload stuff in and it doesn't affect other people. It doesn't make you more vulnerable as the owner of the system or who uses the application, it is a better approach. But like I said there is a Media Manager. If you go to content, there is a Media Manager and a media file type which [01:19:07](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h19m07s) works very well, and can also add this kind of functionality to your component, if this is a little bit too a big of a challenge for you.
