Zend File Upload -- Access data in file

Question

I'm building a site in Zend that requires the ability to upload a list of email addresses via a file upload. This will end up populating a distribution list table.

What I'd like to do is have the user complete the form, including the attached file, then upon submit, I will parse the file and submit the form for each line of the file.

Ex. User completes the form with the distribution list name, and uploads a file ( properly formatted)

On submit, I need to parse the file for each email address, then add a row of data to the table with the distribution list name and a new address.

Any ideas, I'm open to all suggestions.

Thanks for the help, you guys are awesome

Assuming that you are actually getting the file onto the server already (as described in the manual), then you're not really dealing with a Zend, or even an upload, issue, any more. You're simply dealing with a "read and parse data in a file" issue.

Start by looking at PHP's filesystem documentation

Assuming your files aren't huge, and you've got one email address per line, you might do something like:

<?PHP
$data = file_get_contents('/path/to/your/uploaded/file');
$data = explode("\n",$data);
foreach($data as $address){
   //validate each address, and if valid, safely insert into your database
}

if you've got many thousands of email addresses in the file, you might want to avoid loading them all into memory at once. In that case, use fopen, and loop/fgets each line.

If you need to parse CSV data, fgetcsv will save you many headaches.

See the code examples at the above-linked PHP manual pages for more guidance on looping over file data.
