|Welcome back.  In the first part of this tutorial, I showed you how to take out specific properties of our uploaded file using this form here.

|Now I'll show you how to upload this file and move it to the uploaded folder here which is currently empty.

|If you recall, we're referring to a temporary area that is being stored on our web server.

|Its not of much use right now.

|We have all our properties here, so I'll say properties of the uploaded file so we know what we're doing.

|I've given all of them easy to remember variable names so we don't need to comment each of these individually.

|First thing we will do is create an 'if' statement to check if there are any errors.

|Here if error code is bigger than zero meaning it has been issued by an error code then I'll say 'die'  

|Or 'Error uploading file, code error'.

|Now the 'else' part.  

|So 'else' I want to use a function called 'move_uploaded_file'.

|Then we'll take the temporary name 'temp', which is the first parameter of this function and the second parameter is the destination which is 'uploaded folder'

|So I'll type 'uploaded' and a forward slash.

|And at the end of that we'll concatenate the name the file that we've uploaded.

|So here it would just be 'name'.

|Otherwise we would have to type these, for example - temp name.

|So its easier to just keep these variables here.

|Okay so now I'll get rid of these or rather I'll keep these.

|And lastly echo out a message saying 'Upload complete'.

|Lets try this.

|I'll click on upload and we can see that upload is complete.  

|Lets check my file.

|Upload folder and click on my uploaded sub directory you can see that the file is here whereas before - it had been stored in the temporary directory on my web server.

|Undo another 'if' statement or undo this 'if' statement.  

|So for example lets say I don't want avi files to be uploaded.

|What I could do here is say - if error is bigger than zero, don't upload files.  

|Otherwise I'll start a new 'if'  statement inside the else

|And I'll create a block here.

|And these are the conditions for the file.

|I'll say - if the type of file - that's our type variable, t-y-p-e, 2 equal to signs, equals video dot avi.

|And then we're saying that if it is equal to video dot avi then upload the file.

|I'll just move it down here and I will put that into the 'else' block.

|So now I have - if the video is equal to avi then die and the message is 'That format is not allowed'.

|Okay so now I'll delete this from our uploaded directory and I'll come back to my initial uploaded file.

|I'll choose intro dot avi and when I click upload it says that that 'format is not allowed'

|And if you go to my uploaded directory you can see that the folder is empty.

|Now instead of avi let us say I want to ban 'images with png' extension.

|You can see that because its an accepted file format, we get the message 'Upload complete' and its been transferred to my uploaded folder.

|Lets delete that again.  Oh! I canceled it.  Lets delete that again.

|I'll say 'or' using this 'or' operator and I'll say 'or' the size is bigger than half a megabyte.

|This is half a megabyte, which is five hundred thousand bits sorry bytes.  I think I made a mistake and said bits instead of bytes.

|Then it will say this format is not allowed.

|So I'll change this message to accommodate 'Format not allowed or file size too big'.

|So you can create an if statement for each of these that is for evaluating your type and evaluating your size.

|You just need to take this condition and put it in another 'if' statement.

|So I go back here and I'll choose my file again.

|Just making sure its there.

|Click upload and it'll say 'Format not allowed'.

|Now if you go back to our code this is not in png format but it is exceeding the size limit.

|Lets change this to 2 million which is 2 megabytes.

|That's all I have on File Upload for now.  

|This is all you need to know to use this to keep out specific file types and file sizes that are too large for your web server.

|If you don't want big files on your web server this is a good way to control it.

|Its very easy to create as you've seen.
