Re: [PHP] Uploaded CSV -> database
Amazing - it works! The uploaded file is always stored in the temp
directory, so that issue was kind of moot. Here's my complete code,
if anyone else has this same need:
if(isset($_FILES['userfile']['tmp_name'])) {
$csvfile = fopen($_FILES['userfile']['tmp_name'], "r");
if($csvfile == FALSE) die('error opening file');
while(($datarow = fgetcsv($csvfile, 1000)) !== FALSE) {
$name = isset($datarow[0]) ? $datarow[0] : '';
$addr = isset($datarow[1]) ? $datarow[1] : '';
$city = isset($datarow[4]) ? $datarow[4] : '';
$state = isset($datarow[5]) ? $datarow[5] : '';
$zip = isset($datarow[6]) ? $datarow[6] : '';
$query = "insert into dealers
(account_id,name,addr,city,state) values
('$account_id','$name','$addr','$city','$state','$zip');";
$result = mysql_query($query) or die(mysql_error());
}
fclose($csvfile);
}
I was really surprised at how short & simple this turned out to be.
There is plenty of room for error-checking in the above snippet, but
what's there works when there are no problems.

Re: [PHP] Uploaded CSV -> database
This discussion is starting to go over my head, but fgetscv works with
uploaded files (in PHP5 anyway). Here's some sample code:
if(isset($_FILES['userfile']['tmp_name'])){
$csvfile=fopen($_FILES['userfile']['tmp_name'],"rb");
if($csvfile==FALSE){die('error opening file');};
while(($aryData=fgetcsv($csvfile))!==FALSE){
//etc
}

Re: [PHP] Uploaded CSV -> database
Actually I think fgetcsv will work with any valid file pointer and at
least in PHP 5, the streams implementation will allow you to use a variety
of protocols to create the stream.
http://us2.php.net/manual/en/wrappers.php
I understand that it isn't even too teribbly difficult to implement your
own stream if one isn't already to your liking, but I'm afraid I haven't
found need to go beyond the simple read-a-file-from disk style operation.

It looks like all of those tips will easily cover me for the latter
half of the operation. Any tips on how to get the uploaded CSV file
into memory in order to attack it with fgetcsv()? I'd rather
not ever
have to actually write the file to the server's disk.
Thanks!
If you are using the "standard" file upload facilities, your file is
being
written to disk when it is being uploaded. As far as I can tell,
fgetcsv()
will only read a file from disk:
$num fields in line $row: \n";
$row++;
for ($c=0; $c < $num; $c++) {
print $data[$c] . "\n";
}
}
fclose ($handle);
?>
If you are instead using a socket connection to receive the file in a
stream
from the client, you could assign it to a string variable, and use
explode().
These are fairly uncharted territories for me, so others will likely have
better answers.

[/snip]
Once you have performed move_uploaded_file() you will have to fopen and loop
through the file to read and perform error checking. After you have
processed the file you could then unlink() it, removing it from the server's
disk. Here is an example where Excel files are uploaded as tab delimited
text;
/*real file name*/
$fileName = ($HTTP_POST_FILES['docfile']['name']);
$docWork = "/path/to/file/after/move/";
move_uploaded_file($HTTP_POST_FILES['docfile']['tmp_name'], $docWork .
$fileName) or die("File cannot be uploaded");
/*
** open uploaded file and do stuff to it
*/
$i = 0;
$fileTab = fopen($docWork.$fileName, "r");
while(!feof($fileTab)){
$fileLine = fgets($fileTab, 1024);
$arrLine = explode("\t", $fileLine);
$cmLength = strlen($arrLine[0]);
/* do other stuff here */
}
fclose($fileTab);
