Multiple Image Upload

darkknight943

Hello,

I have stong background in many applications, however I am somewhat new to PHP. I have a few things I am trying to do. I would like to be able to have a user upload multiple images to a folder on my remote server. 5 images to be exact.

I have seen many different basic scripts but have yet to run accross one that entails everything I would like to see. I would like to have some sort of security in the code to prevent any mallicious files from being uploaded to my server.

I am also looking for a way to Rename the files. For Example I will have users uploading 5 images of themselves and I would like to give a unique name to each image but also group those 5 images so I know they are all from the same person.

Example.

xyz1
xyz2
xyz3
xyz4
xyz5

The next person to upload would have something different

yyy1
yyy2
etc.

and last I would like to have a field were the user can enter their email address, so I know whos pictures are whos when they upload into the upload folder on the server. In other words someway to identify the person uploading.

I don't know how difficult this is. I have seen bits and pieces in scripts around but unfortanetly I don't exactly know how to put it all together.

Any help would be much appreciated.

Thank you for your time.

if the user added his email address, save in a database, call it email table

save a random key with the email, and a registration date, to be able to send a vaerification link to the email. If the user clicks on the link, then ask a password. If a user wanted to upload 5 images with a reserved email address which has verified, ask that password. You need to handle the several cases:
email hasn't been verified, delete it from the database.

If a user don't know the password, access should denied, and the uploaded images will deleted.

On upload, you register the email address into the email table, and have the email_ID(the primary key)

Create a folder with the email_ID, where you upload the images. If 2 user wanted to upload frog.jpg, the names won't overwrite each other.

How you should store the images and its file names in database?

User uploaded 5 files. You can use the $_FILES array to know the file types. If these are the acceptable, you save the base-names into the images table, then evry names will have a unique primary ID. You save the email_ID into the images table as foreign key. Lets move the uploaded files from the temporary folder into its destination place renamed based on the primary keys from last inserts.
upload folder/{$email_ID}/$last_insert
==>>> for cycle to list the uploaded files, checking the types will fill error message if any. The examples are good on php.net about move_uploaded_files()

Hello, jjozsi.

You deinetly seem like you kow what your talking about, but unfortanetly I am quite lost with all of this. I don't have clue how to this. I understand the concept with a MYSQL database and how it would all integrate but I have no idea as to what the PHP code would look like to make all of this work and how to setup the MYSQLdatabase.

I won't even try to ask you to help with all of this because I'm sure its way to time consuming. Thank you for your help though. I really appreciate it, but this sounds a bit to advance for me. Do you have any easy suggestions.

Realistically if I can just get the images to upload into a folder on my server and have someway to identify the user. Maybe have the 5 upload fields and then a field for them to put their email address in. I just need to know how I could group the 5 images with the email address on the server.

Or better yet is there a way so that the 5 images "names" with the persons email address is emailed to me when they upload. Kinda of how a standard form would work that sends you the users input they typed in a form's fields?

If this is a possibility I could see the users email address and the images "names" they uploaded and go to my server and grab the necesary photos from the file...

Thanks

Do you have any easy suggestions.

yes, this project consists of little pieces.

database for the tables
create tables for emails and images
3 registration into the email table with password
4 email verification with an email activation sen via mail()
5 file field form
6 after a submit you need to check the 5 file formats
7 if the user tried to upload images with an email address which has'nt been activated, you need to stop uploading.
8 email and password added, all ok, you need to select the email's primary key from the emails table, and save the file names into an images table, where you store the email's primary key.
9 you need to rename the images according to the last inserted primary keys.

3 images uploaded, the newest value in the primary field 6,7,8

you can rename the files into the upload folder 6 , 7 , 8

I can help with a limited version, where i determined the maximum image per email uploads. cos i've got an upload form generator for projects like your's.

lets see this page: video tutorial here about a project like this watch in HD

darkknight943

Sorry its still to complicated for me. I'm afraid I need to be walked through it in detail. I did try your generator though.

I made 6 fields.

1 email address field.
5 Image upload fields.

I got the php code and the sql code, setup the database and inserted the code.

created the form folder, placed the php code in it, and created an upload folder.

However I am getting an error.

Parse error: syntax error, unexpected T_STRING in /home/content/y/u/k/yukon721/html/form/uploadimages.php on line 37

This is line 37 of the code:
$f_User Name=isset($POST["f User Name"])? mysql_real_escape_string($POST["f User Name"]):"";

Any ideas?

Thanks

spaces in the variable name is not suggested.

darkknight943

OK, got rid of spaces. That took care of that error, now I'm getting

Warning: mysql_connect() [function.mysql-connect]: Lost connection to MySQL server during query in /home/content/y/u/k/yukon721/html/form/uploadimages.php on line 10
Can't connect to MySQL

Here is Line 10 of the code:

$connection=mysql_connect("$hostname","$user","$pass")

darkknight943

Nevermind... I got it to connect to the databse, still having a few issues though. Keep you posted after I play with it a bit.

Thank you

darkknight943

OK so I got the uploadimages.php page to show correct.

Name
Email
image_1
image_2
image_3
image_4
image_5

I can enter the information and choose the image I want to upload, but when I hit the submit button, instead of going to my access.html page it says:

Please check these errors:
Email is a required field.
image_1 is a required field.
image_2 is a required field.
image_3 is a required field.
image_4 is a required field.
image_5 is a required field.
Name
Email
image_1
image_2
image_3
image_4
image_5

Name is the only field that doesn't error. All the fields have a image or text in them but it comes back with those fields required????

Any ideas? Sorry, I wish I was better with this stuff. I'm a designer, not so much a developer. My specialty is Flash and I just never reallydove into all this PHP, MYSQL stuff, although I would really like to learn.

Thanks.

darkknight943

I got it to work. Thank you so much. You've really helped so much, you have no idea. I've been trying to get something like this to work for quite sometime.

I have a couple more questions for you.

Do you have any php snippets of code that will check to see if the files being uploaded are images? (JPEG, JPG, GIF, PNG)

And is there any snippet of code that will stop duplicate files. in other words if someone uploads the same named image file it will automatically rename it for me instead of overwrite it?

That would be great if you do.

Thanks again.

hy,
i'm back from an interruption 🙂

the required fields can set in the generator around the 'is required field' textfield.

If you did not see the video i suggest lets have a look it. i'm explained how to set the required field.

This snipet if not always a full solution, but makes the biggest part you need to create a table in mysql, and make an INSERT sql code.

i have miles of codes to check if an image is in a correct format, but the shortest is the better. After upload, you can check the $_FILES["file_variablename"]["type"] to know the file's file type. i often solve it with an array.

$accept=array("image/jpeg", "image/pjpeg", "image/png" , "image/gif");

how to know if the uploaded file is in a rightr format?

check if the file type is in the array:

if(!in_array($_FILES["file_variablename"]["type"] , $accept))
$error[]="The uploaded file is not acceptable!";

$uploadfolder="images";
$file=basename($_FILES["upl"]["name"]);
if(file_exists("$uploadfolder/$file"))
{
$file= sha1(microtime()) . $file;
}
move_uplo........
.... entire code.

Hello,

I was able to get everything to work for one database a couple months ago. You helped me out tremendously. However I need to create a new database and for some reason I am getting the error when I created it.

Unknown column 'email' in 'field list'

Any ideas why this might be happening?

Is there a field name email in your table? Did you mispelled, try Email ...
You should open a new thread to answer this new project. If you can, please send me the new thread's url, cos I haven't got time to watch the new questions.
