[PHP-DB] Settings to Allow Precise File Upload Bytes
Please advise the proper settings (Apache/PHP/HTML/MySQL/Anything else
I missed) to allow a specific byte size upload and to deny 1 byte over
with error reporting in LAMP/AJAX. I've heard of Flash and Gears
solutions, but these require additional installs for the user -- just
to know the file size before an upload.
The server is Apache 2.
PHP is 5.1.6
HTML has
!DOCTYPE html
input type=hidden name=MAX_FILE_SIZE value=103 /
input type=file name=attachment /
PHP ini :
file_uploadsOn On
upload_max_filesize 2M 2M
post_max_size 8M 8M
I believe MySQL max_allowed_packet 1,048,576 was affecting the MySQL
INSERT, so I changed MAX_FILE_SIZE to 103 above.
Now I am seeing cases where
if(isset($_FILES['attachment']) $_FILES['attachment']['size'] 0){
evaluates to FALSE
How can I know that a file upload was attempted yet failed or will fail?
My last test case had the web page still claiming it was busy, yet I
noticed that the above condition must have evaluated to FALSE, failing
silently due to missing error reporting on my part (or the system's
part).
I am willing to make 2 requests:
1) just to find out if the attempted upload will fail and inform the user.
2) for the actual upload if it should succeed.

Do you know the correct settings on any applicable LAMP/AJAX stack to

hopefully something is in $_FILES['attachment']['error']?

All checking of how large a file is has to happen client-side. Due to
security reasons, languages such as javascript are not allowed to view any
details about files on your disk, and thus can't be used to determine the
filesize before sending anything to the server.
The reason flash and gears can do this, is because these are designed
differently and actually form a separate program inside your browser, which
is not limited in its activity, as javascript (and vbscript in IE) are.
So... you can use Flash and Gears to prevent upload of a too large file to
your server. But not plain HTML and/or javascript. Since the server does not
check the size until AFTER it has fully downloaded the file, there is no
setting in Apache, PHP, MySQL (which has absolutely nothing to do with
uploading at all), etc. Which are all server-side and ran after the upload
has finished.
In other words: use the Flash/Gears solution, or just decide you don't mind
if a large file is uploaded. In the last case you can always reject the file
afterwards.

[PHP-DB] Re: Settings to Allow Precise File Upload Bytes
My browser is claiming it is still busy from a 1MB (1030001 bytes)
upload where I was trying to find out if it is setting
$_FILES['attachment'].
Thanks Maciek. It makes sense that I should be looking at
$_FILES['attachment']['error'] before the size. I'm just surprised
it's still hanging. I'm using jquery mobile which has extra file
upload concerns (although there is no problem when the file is small
enough).
The MySQL part was included so that this post could help others if
they missed a setting in their LAMP/AJAX stack, but I had narrowed my
specific issue down to PHP $_FILES['attachment'].
Thanks for all your help Jim.

No, the server downloads, the client uploads. Downloading is performed by
the receiving end (in this case, the server), while uploading is done by the
serving end (in this case, the client). But that's a minor thing.

I decided to post here instead of trying various permutations.
MySQL max_allowed_packet was mentioned because even if you correct #8,
MySQL can choke on what Apache allowed through, and I included the DB
list.
After rereading your post I noticed I had failed to read correctly. I'm
sorry. However, I still believe that the MySQL settings are not of any
interest here. The limitation should IMO be performed by PHP (or even
apache). By the time it gets to MySQL, all such checks should already have
been done. So let's ignore MySQL for now.
As for PHP:
$_FILES['attachment']['error'] should be 0 if the file is uploaded
correctly. If it's 0, then you should throw an error regardless of size.
So, assuming $_FILES['attachment']['error'] == 0,
$_FILES['attachment']['size'] will give you the exact filesize in bytes.
Check against this number, and you should be fine.
However, if the upload size was higher than php.ini's upload_max_filesize,
$_FILES['attachment']['error'] will have the value 1 (constant:
UPLOAD_ERR_INI_SIZE), and will not be available to handle.
So, in short, with code like:
define('CUSTOM_MAX_UPLOAD_SIZE', (10*1024*1024) ); // 10MB
if( isset($_FILES['attachment']) $_FILES['attachment']['error'] = 1 )
{
if( ($_FILES['attachment']['error'] == 1) or
($_FILES['attachment']['error'] == 0 $_FILES['attachment']['size']
CUSTOM_MAX_UPLOAD_SIZE) ) {
exit('ERROR: upload too big');
} else {
// process the upload, store it, etc.
}
} else {
// something went wrong while uploading
}
You should be fine.
Of course, you should also check that your max request body size is large
enough in Apache, though usually it allows requests far larger than PHP
does.
Hope this helps, and sorry if I sounded rude at first,

[PHP-DB] Help to improve MySQL query
A database was designed with the following tables: Incidents _ id (auto incremented int) ... Calls _ id (auto incremented int) incidentId (foreign key) status (varchar 32) ... The status of the last Call is the status of the related Incident. Statuses can be Not started through various states up to Completed. The status column never has the text Open. If the last Call for the related Incident is not Completed, then it is considered to be Open. My task is to getIncidentsWithStatus(Open) using PHP. The existing inefficient method is in the PHP function getIncidentsWithStatus($status = Open), made worse by mingling with PHP and then another MySQL query. It first finds $theHugeListOfIncidentIds of the last Calls OF ALL INCIDENTS, then uses Calls.id IN ($theHugeListOfIncidentIds) AND Calls.status NOT LIKE 'Completed'. The reason this was done was that if Calls.status NOT LIKE 'Completed' was used first, then the result would include all Incidents. A) What would be an efficient MySQL query with the database in the present state to getIncidentsWithStatus(Open)? I can think of two alternatives, which require the database to be modified: 1a) Add a trigger to update a new column named statusFromCall in the Incidents table when the Calls.status is updated. 1b) Add PHP code to update the new column named statusFromCall in the Incidents table when the Calls.status is updated. 2) Then just query for Incidents WHERE statusFromCall NOT LIKE 'Completed'.

[PHP-DB] Partial UPDATE execution? Perl DBI MySQL
Has anyone ever seen a partial execution of an UPDATE statement? I'm using Perl DBI to update a table in MySQL. The strangest thing to me is that a varchar(35) field which holds a custom date/time format was updated correctly, but other tinyint(1) fields were not set correctly, and 1 of 3 text fields which were supposed to add the new log to existing logs in the 3 fields did not appear in the 1 field, but did in the other 2. I found the query in the mysql query log file and some of the text had newlines. So I thought the query may have failed at this point, BUT when manually executing the query in phpMyAdmin, it executed fine. I thought the whole query would fail due to possibly not escaping some characters. BUT, like I said before, even this logic is incorrect because some fields were updated before my manual attempt at testing the query. The only similar behavior I've seen is using C/C++ with printf and sometimes you need to add a flush statement so the text really prints. Basically for 5 years, this script has used the following sequence (prepare, execute, finish). But there have been recent changes to the script. Only one record is showing this strange behavior (but it most likely touches code that other records do not). After the successful manual execution of the statement, the 3 text fields do not verify my claim that 1 in 3 had previously failed. BUT the custom date/time field was confirmed by a few people to have been updated (when other fields were not), so I may not be going crazy. This is a single UPDATE statement. No transactions are involved. TIA
[PHP-DB] Fun with MySQL collation, HTML charset and PHP utf8_encode
How do I avoid having so much fun using utf8_encode throughout my document?
I was thinking of using output buffering and then making 1 call to
utf8_encode, but I think a better question is, how do I stop using
utf8_encode completely?
The docs say that utf8_encode Encodes an ISO-8859-1 string to UTF-8.
So if I start with a UTF-8 string, why should I need to use
utf8_encode? Am I really starting with a UTF-8 string if I set MySQL
to utf_unicode_ci for that field, set the content type with
header('Content-type: text/html; charset=utf-8'); and set the HTML
charset with meta http-equiv=content-type content=text/html;
charset=utf-8 ?
In MySQL 5.0.22, I had a Type text, Collation latin1_swedish_ci field
(default settings, I believe) which I pasted the character é from
the French Keyboard Viewer on a Mac Leopard machine into phpMyAdmin
2.11.1.2. This is an e with an accent on top (in case it is not
rendered properly in your email client).
Hmm, pulling the phpMyAdmin version reveals:
MySQL charset: UTF-8 Unicode (utf8)
MySQL connection collation: utf_unicode_ci
I retrieve the field using mysql_fetch_assoc and display it in an HTML
page rendered by PHP with and without
header('Content-type: text/html; charset=utf-8');
and
meta http-equiv=content-type content=text/html; charset=utf-8
The document was originally saved in Dreamweaver 8 as a Unicode
Normalization Form: C (Canonical Decompositon, followed by Canonical
Composition) without Include Unicode Signature (BOM) -- great more
encoding to worry about in my editor.
The rendered view I see in Firefox 2.0.0.12 is a question mark ?
where the French character should have appeared. If I use
utf8_encode, the character appears as it should.
I had changed the MySQL Collation to utf8_general_ci and
utf8_unicode_ci and I still have to use utf8_encode to see the
character appear properly.
Luckily I'm on PHP 4.3.10, so I can't see what mb_check_encoding would
report -- if that would even help normally.
Don't you just love Monday fun?

[PHP-DB] Query Across DBMS Boundaries (Linked Database Servers?)
Is there something which can perform a query across different database systems?
It would extend the database.table.field notation to maybe
dbms.database.table.field and allow queries across MySQL and MSSQL
such as:
//$sql =
SELECT MySQLidentifier.aDatabase.aTable.aField,
MSSQLidentifier.anotherDatabase.anotherTable.anotherField
FROM MySQLidentifier.aDatabase.aTable,
MSSQLidentifier.anotherDatabase.anotherTable
WHERE MySQLidentifier.aDatabase.aTable.aKeyField =
MSSQLidentifier.anotherDatabase.anotherTable.anotherKeyField
//Or through JOINS, etc.
I've seen the linked server option in MSSQL. Technically I can write
to MSSQL, but company policy prohibits it. To steer clear of
ambiguity, personally I've decided that I will also not create
triggers (or any object) on MSSQL (which is a write in my mind).
Basically I will only read information from MSSQL.
I was thinking of PDO, which raises an interesting distinction of
data-access abstraction layer versus database abstraction (which as I
understand means no SQL rewrite or missing feature emulation -- SQL
rewrite example: TOP n prefix versus LIMIT n suffix). The PDO
developers may be close to creating such a feature.
$MySQLidentifier = new PDO('mysql:host=localhost;dbname=test', $user, $pass);
$MSSQLidentifier = new PDO('mssql:host=localhost;dbname=test', $user, $pass);
$dbh = new PDO_LinkedServers($MySQLidentifier, $MSSQLidentifier);
$dbh-exec($sql);
Looking at MSSQL's OPENQUERY syntax, I don't even know if MSSQL
provides this extended query notation. It just seems to allow a query
on a remote (or distributed) server.
Regards.

Wow! I just found the Federated Storage Engine. http://dev.mysql.com/tech-resources/articles/mysql-federated-storage.html It's not in our SHOW ENGINES though. I still welcome comments. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Form mail() problem
Normally I'd say, If it's been working fine for 3 months; then just stopped working; don't get angry at the PHP programmer; check with the network admin as to what changed. But it's interesting that your error came from an MS Windows machine, while you have links at the bottom from an Apple machine. Did someone move your working code from one machine to another?

Not sure what you mean. global $db should bring to local scope a reference to the object that has the data base connection. PHP complaints that it cannot access properties or methods of that object in the obj/f1/ scope I tried using the $GLOBALS['db'] with same results. In the one that failed, you used the invalid keyword globals. In the one that worked, you used the valid keyword global. When I said hopefully, I was wondering if you could use $GLOBALS['db'] but there may be other issues since you said that also failed. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Re: passing a mysqli object via globals
no worries I give up. It is really weird I know Hope some day I will get enlighted. In one file, any method within a class is happy with the global $db...on a different (same file !!!) class no method is happy with accessing $db via global... So you confirmed that you are using global instead of what you posted to the list as globals? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Sending value to another page...
I was going to guess: echo ($_GET['OrderNumber']); But I don't use that form. I use echo $_GET['OrderNumber']; But now I need to check out that quoted URL ... ?'OrderNumber'=TEST222808 as well. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Sending value to another page...
I just tested ?'OrderNumber'=TEST222808 and it works with and without quotes. The problem is you have echo (['OrderNumber']) when you need echo $_GET['OrderNumber']; or possibly echo ($_GET['OrderNumber']); -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
