I need to upload a csv file to a server. works fine for smaller files but when the file is 3-6 meg its not working.
$allowedExtensions = array("csv");
foreach ($_FILES as $file) {
if ($file['tmp_name'] > '') {
if (!in_array(end(explode(".", strtolower($file['name']))), $allowedExtensions)) {
die($file['name'].' is an invalid file type!<br/>'. '<a href="javascript:history.go(-1);">'. '<< Go Back</a>');
}
if (move_uploaded_file($file['tmp_name'], $uploadfile)) {
echo "File is valid, and was successfully uploaded.
";
} else {
echo "Possible file upload attack!
";
}
echo "File has been uploaded";
}
//upload form
<form name="upload" enctype="multipart/form-data" action="<? echo $_SERVER['php_self'];?>?action=upload_process" method="POST">
<!-- MAX_FILE_SIZE must precede the file input field -->
<input type="hidden" name="MAX_FILE_SIZE" value="31457280" />
<!-- Name of input element determines name in $_FILES array -->
Send this file: <input name="userfile" type="file" />
<input type="submit" value="Send File" />
</form>
I have also added this to htaccess
php_value upload_max_filesize 20M
php_value post_max_size 20M
php_value max_execution_time 200
php_value max_input_time 200
Where am i going wrong?
What is the value of $_FILES['userfile']['error']? Have a look here:
http://php.net/manual/en/features.file-upload.errors.php
Also, whats with this:
if ($file['tmp_name'] > '') {
I don't think that's very healthy.
Check your php.ini file and see if upload_max_filesize in there is set higher than 3 MB, I don't know if the .htaccess has precedence over the php.ini.
The default upload limit on debian php5 is 2MB if I recall correctly, but I am not sure what system you are running on.
You can also check the php values if you create a file e.g. info.php and put it in the same directory as your "problem php script".
The file content should look like this <?php phpinfo(); ?>
This will give you all php relevant values referring to the directory you are in, hope it helps.
Just some suggestions to your code
($file['tmp_name'] > '') should be something like ( ! empty($file['tmp_name']))$_SERVER['php_self'] should be capitalised because it is a constant, i.e. $_SERVER['PHP_SELF'].Check your apache error logs and the error should be there?
