|-
|0:00
|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.
|-
|0:10
|Now I'll show you how to upload this file and move it to the uploaded folder here which is currently empty.
|-
|0:18
|If you recall, we're referring to a temporary area that is being stored on our web server.
|-
|0:25
|Its not of much use right now.
|-
|0:29
|We have all our properties here, so I'll say properties of the uploaded file so we know what we're doing.
|-
|0:34
|We have all our specific properties here.
|-
|0:38
|I've given all of them easy to remember variable names so we don't need to comment each of these individually.
|-
|0:46
|First thing we will do is create an 'if' statement to check if there are any errors.
|-
|0:53
|Here if error code is bigger than zero meaning it has been issued by an error code then I'll say 'die'
|-
|1:03
|And I will give an error message out "File couldn't..."
|-
|1:11
|Or 'Error uploading file, code error'.
|-
|1:20
|This will give the user an error code.
|-
|1:23
|Now the 'else' part.
|-
|1:25
|I'll add these curly brackets to keep that simple and in a single line.
|-
|1:29
|So 'else' I want to use a function called 'move_uploaded_file'.
|-
|1:39
|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'
|-
|1:51
|So I'll type 'uploaded' and a forward slash.
|-
|1:59
|And at the end of that we'll concatenate the name the file that we've uploaded.
|-
|2:07
|So here it would just be 'name'.
|-
|2:10
|This shows the user just adding the inter variables here.
|-
|2:15
|Otherwise we would have to type these, for example - temp name.
|-
|2:19
|Then go here and place it like this.
|-
|2:22
|It gets quite messy and hard to read.
|-
|2:25
|So its easier to just keep these variables here.
|-
|2:33
|Okay so now I'll get rid of these or rather I'll keep these.
|-
|2:37
|And lastly echo out a message saying 'Upload complete'.
|-
|2:41
|Lets try this.
|-
|2:47
|I logon to our page and pick our file - 'intro to avi'.
|-
|2:51
|I'll click on upload and we can see that upload is complete.
|-
|2:55
|Lets check my file.
|-
|2:57
|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.
|-
|3:08
|So we've successfully uploaded our file here.
|-
|3:13
|There are a few more things that we need to do.
|-
|3:15
|Undo another 'if' statement or undo this 'if' statement.
|-
|3:20
|We are going to check for specific file types that we don't want uploaded.
|-
|3:24
|So for example lets say I don't want avi files to be uploaded.
|-
|3:30
|What I could do here is say - if error is bigger than zero, don't upload files.
|-
|3:37
|Otherwise I'll start a new 'if' statement inside the else
|-
|3:41
|And I'll create a block here.
|-
|3:47
|And these are the conditions for the file.
|-
|3:51
|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.
|-
|4:09
|As you saw in the first part of this, as I echoed it out, it was equal to video dot avi.
|-
|4:19
|And then we're saying that if it is equal to video dot avi then upload the file.
|-
|4:28
|I'll just move it down here and I will put that into the 'else' block.
|-
|4:32
|So now I have - if the video is equal to avi then die and the message is 'That format is not allowed'.
|-
|4:44
|Okay so now I'll delete this from our uploaded directory and I'll come back to my initial uploaded file.
|-
|4:54
|I'll choose intro dot avi and when I click upload it says that that 'format is not allowed'
|-
|5:01
|And if you go to my uploaded directory you can see that the folder is empty.
|-
|5:06
|Nothing has been uploaded.
|-
|5:08
|Now instead of avi let us say I want to ban 'images with png' extension.
|-
|5:15
|I'll change it here and upload my file again.
|-
|5:23
|You can see that because its an accepted file format, we get the message 'Upload complete' and its been transferred to my uploaded folder.
|-
|5:33
|Lets delete that again. Oh! I canceled it. Lets delete that again.
|-
|5:42
|Okay. So what we've seen here is how to specify a specific type.
|-
|5:47
|What we also can do is specify a specific file size.
|-
|5:51
|I'll say 'or' using this 'or' operator and I'll say 'or' the size is bigger than half a megabyte.
|-
|6:04
|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.
|-
|6:14
|So that's five hundred thousand bytes which is equal to 0 point 4 megabytes. I'll just say half a megabyte for now.
|-
|6:29
|This will evaluate the size and say is it bigger than half a megabyte.
|-
|6:38
|Then it will say this format is not allowed.
|-
|6:43
|So I'll change this message to accommodate 'Format not allowed or file size too big'.
|-
|6:56
|So you can create an if statement for each of these that is for evaluating your type and evaluating your size.
|-
|7:03
|You just need to take this condition and put it in another 'if' statement.
|-
|7:09
|So I go back here and I'll choose my file again.
|-
|7:12
|Just making sure its there.
|-
|7:14
|Click upload and it'll say 'Format not allowed'.
|-
|7:19
|Now if you go back to our code this is not in png format but it is exceeding the size limit.
|-
|7:25
|Lets change this to 2 million which is 2 megabytes.
|-
|7:31
|Refresh and send that.
|-
|7:33
|We can see that our upload has been completed because this is only one megabyte in size.
|-
|7:39
|That's all I have on File Upload for now.
|-
|7:44
|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.
|-
|7:54
|If you don't want big files on your web server this is a good way to control it.
|-
|7:58
|Its very easy to create as you've seen.
|-
|8:01
|Practice this and you'll be quite impressed with how useful this can be.
|-
|8:05
|If you've got any questions please don't hesitate to ask.
