[PHP] htmlentities, links, javascript
hi all, i have a script that calls a popup like this: a href=/popup.php?name=Choicesamp;product_id=15 target=_blank onclick=openWindow(this.href,600,200,'yes'); return false;Choices/a the amp; is there to make sure the page validates. the problem is that some browsers seem to be incorrectly translating this to: [REQUEST_URI] = /popup.php?name=Choicesamp;product_id=15 instead of: [REQUEST_URI] = /popup.php?name=Choicesproduct_id=15 a couple of browsers that have choked on this: [HTTP_USER_AGENT] = Mozilla/4.0 (compatible; MSIE 4.0; Windows 95) [HTTP_USER_AGENT] = Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/103u (KHTML, like Gecko) Safari/100 i have safari 1.2.1 installed on one of my development machines, and have had no trouble with the bad REQUEST_URIs. does anyone have some insight into the problem? i've posted a demonstration here: http://hartshorne.ca/sandbox.php you'll have to view the source of the popup to see if the was translated properly. thanks, beau -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] IE6 with latest hotfixes breaks forms ...
Marc: This could be related to the problem I described in detail a few days ago. Here was my solution: http://marc.theaimsgroup.com/?l=php-generalm=107751892631059w=2 Please let us know if this helps! Beau We're having a weird problem with some of our PHP forms, where, when a client uses IE6 with the latest hotfixes, they are reporting that have to re-submit a couple of times for it to take ... as if somehow the data isn't being passed down properly to the FORM/ACTION ... We're using sessions to pass the data around, and it seems to work with every other browser we've used, including IE6 previous to the latest hotfixes ... but, could it be something that *we* aren't doing right, or is there a known bug with sessions + IE6? Some sort of work around? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] PHP or MSIE Problem? -- SOLVED
I described a situation where MSIE for Windows would not post all of a
form's fields under fairly unique circumstances. This problem occurs in
MSIE 5, 5.5, and 6 (with the most recent hotfixes applied). No other
browsers seem to be affected. When:
1. A form is submitted with the enctype attribute set to
multipart/form-data.
2. No http header is sent to explicitly select a character encoding that
matches form input, or if the http header and xml prolog and/or meta
http-equiv=content-type tag do not select the correct character
encoding[1].
3. The user has input a character into one of the form fields, such as
[TM], a curly quote, or some other character that could have been
copy-pasted from a word processor, that is not defined in the character
set identified by some combination of an http header, xml prolog, and
meta tag.
4. There is at least one unchecked checkbox on contained in the form
(thanks Pablo!).
MSIE will not return all of the name/value pairs sent in the posted form
to the server. If you check the checkbox, the form will post normally.
The earliest reference to this problem that I could find was in a German
Usenet post[2,3], where the special character was the Euro sign.
Although the behaviour is a little buggy, we can't blame MSIE for
getting it wrong.
I've posted a new version of my page that sends the correct header:
?php header('Content-type: text/html; charset=utf-8'); ?
And that uses the correct meta tag:
meta http-equiv=content-type content=text/html; charset=utf-8 /
I've omitted the xml prolog because of other problems that it can cause
with MSIE 6.
The page is still posted here:

[PHP] PHP or MSIE Problem?
All, When I submit a form from MSIE, under certain circumstances some of the fields don't make it into the $_POST array. I am building a CMS that accepts images and text entered into an HTML form. If I submit a form from MSIE, and if the text contains special characters (like T [TM] for example), some of the $_POST fields are not populated in PHP. This problem does not occur on Mozilla or Safari. The php version is 4.3.4, and is running on Linux. The MSIE version is 6.0.2800.1106.xpsp2.030422-1633. Here's a demonstration of the problem: http://hartshorne.ca/sandbox.php Can anyone tell me if this is a common problem? Is this a purely MSIE bug, or could PHP be a factor? Thanks!!

RE: [PHP] Cleaning up HTML table structure
Jens, I would suggest that you try writing a script that keeps track of how many tags have been opened (look for ), versus how many tags have been closed ([^]*/) on a line-by-line basis. Using that number, you should be able to indent the code properly. Let us know what you've got so far.

[PHP] instantiating objects
I'm just starting to use PEAR, and have seen several ways of
instantiating the PEAR objects:
$form = new HTML_QuickForm();
$form = new HTML_QuickForm();
$dbh = DB:connect(dsn);
$dbh = new DB();
$mail_object = Mail::factory('sendmail', $params);
Can anyone explain (or point to dome docs that explain) what the
differences are, and when I should be using which method to work with
PEAR objects?
Thank you,
Beau

[PHP] php and file uploads/downloads
Hi, I'm working on a system that allows users to upload and then download pdf files. Each file is related to a mySQL database entry. To keep things simple and consistent, I'd like to store the pdf files like this on the server: [PRIMARY_KEY].pdf But when a user downloads the file, I'd like them to receive something like: [TITLE].pdf Is there a way to get php to rename the file when a user tries to download it?

[PHP] writing functions to preform mysql queries
Hi,
I'm trying to separate my database query code from my application logic.
I want to do this by creating a small application-level library with
functions that INSERT, DELETE and UPDATE specific information in a mysql
database. So I created a file called news_mysql.lib.php and put it in a
/library directory. It has functions that look something like this:
function get_news_item($id)
{
// boundary and error checking, strip out potentially nasty SQL
stuff
// build the SQL statement
$result = $mysql_query($sql);
return mysql_fetch_array($result);
}
// and so on...
My news.php file looks something like:
require_once('path/to/library/news_mysql.lib.php');
$id = $_GET['id'];
$news_item = get_news_item($id);
if (count($news_item) = 0) {
echo 'h1Error/h1'; // deal with the error
} else {
echo 'h1' . $news_item['headline'] . '/h1';
echo 'h4' . $news_item['date'] . '/h4';
echo 'p' . $news_item['body'] . '/p';
}
// and so on...
This works great for UPDATE, INSERT and DELETE statements, but not so
well for SELECT statements that return more than one row.
The first problem is that mysql_fetch_array() works so well for stepping
through the mysql result set, but I don't know how to duplicate it's
functionality in a library function.
The second problem is that even though I might SELECT information from
the same table in a database several times in my application, each time
the query might be a little different. Sometimes I want the information
sorted in a certain way, for example. So I don't want to use a bunch of
bit flags to identify exactly which information I need.
The best I can come up with is to make an exception for the one function
that will return more than one record, and get it to accept an SQL
string as input (instead of a couple parameters), to return a mysql
resource identifier, and then to use mysql_fetch_array on that resource
identifier and step through the results in a while loop as I would
normally.
What's the better way of doing this?
Thank you,
Beau

[PHP] php programming style
Hi,
I'm curious if it's bad coding style for a function to return a value on
success, or simply false on fail. Here's what I mean:
?php
function foo($number)
{
if (is_numeric($number)) {
return $number . ' is a number.';
} else {
return false;
}
}
if ($string = foo(1)) {
echo $string;
} else {
echo 'error';
}
?
Is this ok?
Thank you,
Beau

RE: [PHP] php programming style
I think that some of the above question might help you out. However,
from a programming standpoint i like to make sure that my functions
return the same type at least. Some feel different about this and
return various type (ie, int, strings, arrays)...
I agree that it should return a consistent type. I was planning on
returning a populated array on success, or a boolean false on fail.
Instead, I will return an empty (but initialized) array on fail, and use
the count() function to test for failure like this:
?php
function foo()
{
/* if the result set is empty */
return array();
}
$my_array = foo();
if (count($my_array) = 0) {
// nothing in array
echo 'nothing';
} else {
// do something with data
echo 'something';
}
?

RE: [PHP] Output Buffering - Am I using it correctly?
I guess that this means I am out of luck here. Anyone know a cleaner method for delivering spreadsheets? Can you get the server to write it to a file, and then let the client download the file normally?

RE: [PHP] Output Buffering - Am I using it correctly?
Can you get the server to write it to a file, and then let the client download the file normally? [/snip] Believe me, if I could have taken that way out I would have done it. I am researching some classes, but they all seem to take just as long to create the spreadsheet. What about something like this: 1. Script loads. Script writes everything to some file. 2. Script is finished writing everything to file. 4. Script does a browser redirect and the user starts downloading the file normally. It just seems like the server doesn't want to have to deal with streaming a large database result set to a web browser.

RE: [PHP] Is php even right for this design?
The admin users will need to run long processes that take about 5-15 minutes each. They cannot timeout and they must be done throughout the day while general users are working in the application as well. Is there a big problem with this? What steps should I take to ensure these long processes complete and do not timeout. What about turning these long processes into perl scripts or C programs that can be exec()ed? They'll probably run faster, and they won't time out. I've never done this myself. It's just a suggestion -- does it make sense to do it this way?

RE: [PHP] PHP Execution Timer
This function:
function getmicrotime()
{
list($usec, $sec) = explode( ,microtime());
return ((float)$usec + (float)$sec);
}
is provided on this page:
http://www.php.net/manual/en/function.microtime.php
and is needed for the code below to work properly.
Beau
?
$timerOn = 1; // set to 0 if you want to turn it off $timestart =
getmicrotime(); ?
Bottom:
?
if($timerOn)
{
$timeend = getmicrotime();
$timer = $timeend - $timestart;
echo timer: $timer;
}

Similar things could be done with MySQL quereies, but I haven't looked
into it.

[PHP] Session problems: Warning: write failed: Disk quota exceeded
Hi,
Recently, my php app has started to throw these warnings:
Warning: write failed: Disk quota exceeded (122) in Unknown on line 0
Warning: Failed to write session data (files). Please verify that the
current setting of session.save_path is correct (/tmp) in Unknown on
line 0
I narrowed it down to this code:
?php
session_start();
session_register('anything');
?
(A test file containing only that will throw those two warnings.)
The php version is 4.2.2. This script is running in a shared hosting
environment. My guess is that the ISP has misconfigured php, and has not
set the appropriate permissions to the /tmp directory.
Does this make sense? Or is there something that I've missed?
Thank you,
Beau
