This 'setFileNameArray' is a 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. -???? -So with The add and basic view we actually trigger the set filename array 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 I decrypt them and Load new values to that And then basically 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 Actually adding multiple Media files that only one ended up Being remembered And that sort of the downside Of the current Implementation Is that if the ID doesn't Exist We're not able to actually keep track of that [01:11:55](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h11m55s) So it's only when the ID exist That we are able to Actually do multiple uploads at Once So I should actually Give a little bit heads up of the about that That you want to save the item You're actually ready to To expand upon it And to allow [01:12:13](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h12m13s) Multiple upload at Once So the set filename array is Is really dealing with multiple when you are having multiple so you'll see there is image And document Is when the file I'm using the The plural to tell me That it should allow multiple [01:12:32](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h12m32s) So if it's singular Image And document then I don't allow multiple I'm just gonna remove the old one And add the new Done And when it is plural And we are using the set filename array And we basically building It to [01:12:50](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h12m50s) actually be Multiple And then One thing I didn't Emphasize here Is That we actually remove the files as well There is a remove file right [01:13:06](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h13m06s) There's remove file And it also at some point does a validation To check whether the user has the Permission to remove files And And then will basically remove the file So that is Also and it's Also uses [01:13:23](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h13m23s) Is this file name But then it passes the remove Variable to it Which then means the action is not to add but to take Away and You will see that there The action here There is the Add and there is the take away option So behave still different [01:13:41](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h13m41s) So we still basically get back the array we still build an object and we still updated Database As well as Actually removing the file here Ok so 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 licence That's Only requirement Ok well [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 Basically That needs to be there These things Need to be here so you could Pause the film And Video [01:14:31](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h14m31s) And just make sure that you have the same kind of Ajax Query calls option And then here I am actually Doing some opening of the files You see that I'm building but I'm called links So this is going a little Beyond Just showing you a little bit of my implementation and these links Eventually End up on the page [01:14:57](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h14m57s) So we've go back to Our JavaScript Here Scroll down We see this get filed JS Now let's Again look at that get file JS Because You'll see that those links [01:15:13](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h15m13s) Actually come in To play there If I Remember correctly let see here Oh I see now is not in that JavaScript Is actually down here You see that here I got a Load the links to the page document links And I'm actually adding it to a variable called document links you see [01:15:37](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h15m37s) So in the Custom script Where is it it's not this one It's this one you'll see if I If I now search So I'll take this copy and here I'll search You'll see that I'm actually 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 And so that is how we deal with some of that And it it works very well To sort of pass value from JavaScript to PHP And have it available there Ok well I know this was a lot of [01:16:22](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h16m22s) Things to sort of take in and I would expect you to realize that that previous implementation is So much easier But like you've seen When someone actually does create a document And they Are able to so easily Just drag and Drop stuff And it just crops and It just gives your component so much an easier you know for you feel to it [01:16:52](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h16m52s) Instead of The olds you could still do the old select But the Drag and Drop is Becoming quite popular And this implementation is Really Very Very Yeah it's very nice to have And 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 really gonna give support on to this meaning that If you get stuck you on your own Because if It is really the truth that you will need to know your JavaScript you'll need to know 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 gonna be So easy for me to Do that Specially since I usually 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 have that code has issues in it [01:17:57](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h17m57s) Or errors in it that the That are like ok a very big problem or something Then please do feel free to Give me a heads up over there And we'll collaborate Improve it as Necessary At the end of the day This feature is really way behind What [01:18:19](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h18m19s) What you really need There is a media manager in In Joomla Which is actually ideal The advantage about this way is that your user is Is never gonna interfere with other users documents or images or Stuff So if you use this concept they not ever gonna actually 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 It doesn't affect other people it doesn't make you more vulnerable as the owner of the system Who uses the application So it is I think we better approach But like I said there is a media manager So if you go to content There is a media manager And there is a media file type Which [01:19:07](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h19m07s) Works very well And And can also add These kind of functionality to your component If this is a little bit too challenge To a big of a challenge for you Anyway thanks for watching I know this might again be so such a long Tutorial But I'm trying my very best [01:19:26](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h19m26s) To sort of get you on your feet and you to go.OK. +'setFileNameArray' is another function

'CUSTOMCODE=phpAjaxUploader' needs to be there. These things need to be here(see video).
