Upload File, Renaming

I'm using a basic file uploader and using time in the naming process. This isn't too much of an issue though because all uploaded items will be stored in a corresponding users folder so there's not much chance of a naming clash.

However, I think I've gone wrong somewhere with the script and its storing it under a temp name as the outputted file name went from:

To

Ideally, I'd like the name to be time()_$title and output like:

Not entirely sure how to set this in the code though.

if(isset($_POST['addissue'])) {
 
// use date and time
 
    $random_digit=time();
 
    $target='../publication/1/36/'.basename($_FILES['pdf']['tmp_name'].$random_digit.'.pdf');
    if(move_uploaded_file($_FILES['pdf']['tmp_name'],$target)){
 
 
   
 
/* 
       echo "<input type='text' value='".basename( $_FILES['pdf']['tmp_name']). "$random_digit.pdf' name='pdf'>";
*/
 
}else{
    //There's an error
}
 
    }

What is the best way to move it from a temp name into a custom name? I thought simply removing the ['tmp_name'] would do the trick but it didn't.

Thanks

 

To get a name as you want just change on line no. 7
It will be something like

$target='../publication/1/36/'.$random_digit.'_'.$_FILES['pdf']['name'];

Fantastic thank you.

 

Just another query. This is all working, but now I need to limit the type to PDF only. While I've got this working, its uploading the PDF file before checking/displaying the error and then dropping the file. Is there a way to check before the file uploads? The reason I need to do this is because the files could be onwards and upwards of 50mb so it would obviously take time to upload.

//Add issue
 
 
if(isset($_POST['addissue'])) {
 
    if ($_FILES['pdf']['type'] != "application/pdf") {
 
// Type is not PDF display error
 
    $dialog = '<font color="red"><strong>Error</strong> We can only accept PDF files at this time.
 
} else {
 
 
 
 
    // use timestamp to create unique title
 
    $random_digit=time();
 
    // declare where to upload the file
 
    $target='../publication/1/36/'.$random_digit.'_'.$_FILES['pdf']['name'];
 
    // move the file
    if(move_uploaded_file($_FILES['pdf']['tmp_name'],$target)){
 
 
    // file has been uploaded, set message
        $dialog = '<font color="green"><strong>Success</strong></font> Your publication has been uploaded and is now awaiting moderation.';
 
}else{
    //There's an error
        $dialog = '<font color="red"><strong>Success</strong></font> There was a problem uploading your publication.';
 
    }
 
  }
}

PHP:

 

See http://www.codestore.net/store.nsf/unid/DOMM-4Q8H9E for an example of how to do this in Javascript. That will stop the upload before it occurs if the filetype is wrong.
