Uploaded tmp file not found in query - php

Question

I'm fairly new to php and CakePHP, and I'm trying to execute the following code after uploading a text file (2kb):
$filefullname = $this->request->data['File']['file']['tmp_name'];
debug($filefullname);
move_uploaded_file($filefullname, WWW_ROOT.'tmp.txt');
$query = 'LOAD DATA LOW_PRIORITY INFILE "'.WWW_ROOT.'tmp.txt'.'" INTO TABLE agencies FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY """" LINES TERMINATED BY "\r" IGNORE 1 LINES';
debug($query);
$this->Agency->query($query);
Though the file can be found, I get the following output:
'C:\Windows\Temp\phpB413.tmp'
'LOAD DATA LOW_PRIORITY INFILE "C:\Data\myphpapplication\app\webroot\tmp.txt" INTO TABLE agencies FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY """" LINES TERMINATED BY "\r" IGNORE 1 LINES'
Error: SQLSTATE[HY000]: General error: 29 File 'C:\Data\myphpapplication\app\webroot\tmp.txt' not found (Errcode: 13)
SQL Query: LOAD DATA LOW_PRIORITY INFILE "C:\Data\myphpapplication\app\webroot\tmp.txt" INTO TABLE agencies FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY """" LINES TERMINATED BY "\r" IGNORE 1 LINES
How can I fix this?

Answer 1

Most likely the file is there, but MySQL doesn't allow you to read files from that location. MySQL is fairly restrictive from where it reads LOAD DATA ... INFILE, with good reasons. You may need to move your file first to a path that MySQL can read from, or change the settings for your MySQL server.
From the MySQL 5.1 manual:
Note that, in the non-LOCAL case, these rules mean that a file named
as ./myfile.txt is read from the server's data directory, whereas the
file named as myfile.txt is read from the database directory of the
default database. [...]
And:
Windows path names are specified using forward slashes rather than
backslashes. If you do use backslashes, you must double them.

#JvO is guiding you down the right path. I think you're missing a couple of important elements, one of which is moving the uploaded file from its initial temp directory on the server to a place where MySQL can officially read it (it won't read it from a temp directory for security reasons).
Here's an example from a project I did, which uploaded a CSV file and then MOVED it to a readable directory. I first uploaded it with the move_uploaded_file function, and then created a variable describing the uploaded path of the new file for use in a LOAD DATA query.
move_uploaded_file($_FILES["fCSV"]["tmp_name"],"user_uploads/SG".$dapID ."/". $_FILES["fCSV"]["name"]);
$csvfile = "user_uploads/SG".$dapID ."/". $_FILES["fCSV"]["name"];
In your LOAD DATA query, you're missing the "LOCAL" keyword, which tells MySQL to read the file from a specified directory, otherwise it's looking for it in the database directory (the use of "Field1" etc. below is for demo purposes only and you should have your real table field names in there):
$sqlLoad = "LOAD DATA LOCAL INFILE '".$csvfile."' INTO TABLE my_table FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES (Field1,Field2,Field3,Field4) SET ID =".$id
Lastly, you really need to read through this page in the MySQL manual. It covers many of the issues you're dealing with along with providing examples:
