image upload

rkeppert

I have a .php script to upload a image file to the server and place the image name into a field of my db, so that the photo can be called when viewing the details page...

however, the images upload in whatever name the person has them saved in...

i want to change that, so that it will rename the file based on 2 session variables, as follows:


$_SESSION['constid']       _       $_SESSION['lastname']

not sure how i change the code to do this... but here is the original code:

any help is much appreciated.... i'm trying to get this whole system up and running this week..

thanks.

(only the upload portion provided... the put name into db is working!)


##### IMAGE HANDLING #####

// Where the file is going to be placed 
$target_path = "uploads/images/";

/* Add the original filename to our target path.  

Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['photo']['name']); 
$_FILES['photo']['tmp_name'];  

$target_path = "uploads/images/";

$target_path = $target_path . basename( $_FILES['photo']['name']); 

##### END IMAGE HANDLING #####

That code you've shown us doesn't move or copy any files.

This code is part of the form processing script.

On the page, there is a file selection, and this code is what uploads the file to the server, places it in the correct directory.

In another section of the code that is not displayed here, it places the file name into the database associating the image file with the record that has been created.

What I need to do is have the file renamed when it is uploaded to the server, so that it is in the format of:

userid_lastname.jpg

where

userid comes from the session variable ['constid']

and

lastname comes from one of the fields in the form when submitted ['lastname']

....

Hope this helps.

Thanks.

You made all that clear in your first post. The code you have shown us neither uploads anything nor moves anything. It does appear to set the same variable 4 different times though.

Maybe I am a little confused here, so I'm gonna try to explain what I am seeing, along with the full code being used.

In the HTML form: (where the user selects the file to upload)


<p align="left">PHOTO:
<input type="hidden" name="MAX_FILE_SIZE" value="100000000" />
<input type="file" name="photo" style="width: 222px;" / onKeyUp="highlight(event)" onClick="highlight(event)">

The form processing script: (which tells the server what to do with all the information)


##### IMAGE HANDLING #####

// Where the file is going to be placed 
$target_path = "uploads/images/";

/* Add the original filename to our target path.  

Result is "uploads/images/filename.extension" */
$target_path = $target_path . basename( $_FILES['photo']['name']; 
$_FILES['photo']['tmp_name'];  

##### END IMAGE HANDLING #####

Now. The above code actually does upload the file to the server. How this is uploading the file is beyond me, because what I'm seeing and from everything I've read it should be something like this:


$HTTP_POST_FILES['photo']['name'];

copy($HTTP_POST_FILES['photo']['tmp_name'],
       ($HTTP_POST_FILES['photo']['name']);

So what I need to do with either of the codes is to have the file that is uploaded renamed automatically based on one of the server variables:


$_SESSION['constid']

and the input from a form field from the originating page:


$_POST['warnum']

which is passed from the original form to the .php file with the above name,
set up so that the file name once it is saved to the server would be:

constid _ warnum . jpg

What I can't figure out is how to change the code so that it renames the file to what I need it saved as, so that when the record is called from the database (which has a field in it where the file name is saved with the record) it will display the image file on the details page, along with the record that was accessed.

I think from the details page that I have created, it will call the image by specifying the image location as " uploads/images/['$photo'] "

I hope I am making sense here.... If not please tell me and I will clarify anything that I can.

No it doesn't. All the following code does is to set a variable called $target_path:

##### IMAGE HANDLING #####

// Where the file is going to be placed 
$target_path = "uploads/images/";

/* Add the original filename to our target path.  

Result is "uploads/images/filename.extension" */
$target_path = $target_path . basename( $_FILES['photo']['name']; 
$_FILES['photo']['tmp_name'];  

##### END IMAGE HANDLING #####

I would imagine that $target_path is later used as the destination for a function like [man]move_uploaded_file[/man] or [man]copy[/man] but cannot be sure because you haven't shown us any code containing those function calls.

IF $target_path is indeed the value that gets set to determine where your file gets put then you should set it to something else...whatever you want. You might try something like this:

$target_path = "uploads/images/" . $_SESSION['constid'] . '_' . $_SESSION['lastname'];

HOWEVER I cannot be sure that will do what you want. ALSO you should be careful about what happens when some user tries to upload two photos. Will the file names be different? Might you have to delete some existing file before overwriting it with a new one?
