Yes, by installing the curl libraries. If you are using Windows and PHP
5.0, you can get the curl library DLL from the PECL collection:

http://www.php.net/get/pecl-5.0.4-Win32.zip/from/a/mirror

If you are using Linux, you can add the --with-curl (or was it
--enable-curl) configure argument and re-compile PHP.

Dear you,

Now, I want to define a set of array varible with table structure as the
following:

Result page:

Source page:

<table>
<tr>
for($i=1;$i<5;$i++)
{
<td><input type=checkbox name='f<? echo $i;?>[]' value='1'></td>
}
</tr>
</table>

Only display the result of zero array, eg :
f1[0]
f2[0]
f3[0]
f4[0]

So, how to write the source (Web page - when user click the submit
button) by using loop ?

attached mail follows:

Hi,

There are a couple of problems with your code. The first is that you
have global variables enabled, which makes things easier, but also makes
things less secure. You should definitely disable them in your php.ini
file if possible.

Also, when you put the square brackets after gmev (gmev[]), you turn
$_POST['gmev'] into an array. Yet your code just checks to see if the
$_POST['gmev'] variable has any value at all, which of course, it does.

> if ($gmev) {
> $checked = ' checked="checked"';
> } else {
> $checked = '';
> }

Therefore, when you go to present the form, $checked always has the
string from the first case in the if statement, since you're not
specifying which part of the $gmev array you really care about.

My suggestion to everyone dealing with these form problems, which are a
general pain... Use Lampshade. It's so much easier! You can do this all
in three lines of code: two to set up your choices for the form element,
and one to draw the element itself.

http://www.thinkcomputer.com/software/lampshade

I'd be glad to help you with it if you have any questions.

Best of luck,

Hi All,

As my previous mail about fail on PHP5-MySQL, then I removed all of php.ini (included -recomended and -dist).
Then used phpinfo(), I found there is php still work and found and informed "Configuration File(php.ini) Path = C:\WINNT".

How can this be happenned?
(I believe, this will answer why cannnot load MySQL extension problem on my Win2000)

Thanks in advance for your answer.

attached mail follows:

Actually, my problem is when used phpmyadmin it was generate error "cannot load mysql extension". Then I'm trying to resolve as refer php-manual(included edit system environment), googling but the result is none.

I'm give up, and remove all php.ini to ensure is the problem on php.ini or others.

Any idea, what is wrong?

if there is no php.ini php defaults to whatever is the default for all settings.
and your on windows - php (IIRC) looks for a php.ini in the windows dir if it can't
find on elsewhere (sometimes it live there too)

possibly or php can't find the extension or it a case of that you need to be using the mysqli
extension (and load that) instead mysql.

As you have already found, the default location for php.ini on windows
is the windows directory ( c:\winnt\ on W2k )
PHP5 does not now load MySQL be default since the licence restrictions
changed, and you now need to select the correct version of extension to
match the version of MySQL.
So you need to 'uncomment' extension=php_mysql.dll or
extension=php_mysqli.dll for pre or post Version 4 MySQL

I was uncomment php_mysql.dll and added php_mysqli.dll, put edited php.ini as recommended, also added libmysql.dll on c:\winnt\system32. But it still doesn't work, it still generate "cannot load mysql extension, ...".

Previously, I was edit system variables(edit Path variable by add ;c:\php;c:\php\ext and add PHPRC > value c:\php), also edit Registry as the following :
[HKLM\SOFTWARE\PHP]
"IniFilePath"="C:\PHP"

PHP installed on C:\PHP
Apache 2.0 on C:\Program Files\Apache Group\ ...
MySQL on C:\Program Files\MySQL

I hope, someone can help me to solve the problem before I'm return back to PHP4.

Thanks and Thanks

is that $gmev being created automatically? if so you are
using register_globals - which is one step in the direction of the
dark side - for the love of <insert preferred god/icon/hero/etc> use
the element in the $_POST superglobal array instead i.e.

$_POST['gmev']

it wants an array - your not giving it an array.

how do you think it should be resolved? what about checking the variable
before blindly using it - time to find a way to check if a var is an array
(or even exists in the scope of the current code) ... there is a function
that does this - it's name is so selfevident that I'm not even going to name it

- seek and you shall find.

IMHO every halfbaked php coder should read it ;-)

to cut it short for those to busy, or what not, Rasmus offered his
his vision of php6 (which seems will be the version that will first
bring the awesome unicode [and date?] functionality to the masses
- hey thats us! :-) ) and there seems to be pretty much unanimous
agreement on his main points (lots of discussion on more issues/ideas
other people have brung up in response)

the future's bright, the future is green.

I suppose I am halfbaked. Maybe even a bit burnt and crispy on the
edges, Jochem.

Greatest news I've heard in a long time. Remove register_globals and
magic_quotes_*! Wow. Well, considering that they've been the cause for
most of the simpler PHP hacks that could have been prevented had not
register_globals been active. :P

I am not so sure that removing function aliases and making identifiers
case-sensitive is academic purity alone, though. I consider that a very
good step towards more easily managed code, that way there's only one
function, and no aliases, or case-specific variations thereof.

After reading the responses to Rasmus' post I am delighted to see that
most of the list has agreed to this as well, splendid. Some of these
were what I had expected for 5.x though, so in part I am disappointed
that they were not already removed/implemented.

the problem is BC. given that so many massive changes are scheduled for
what will become 6.0 that will entail BC breakage anyway the core guys seem
to think its a good point to break some more. I think it's sensible,
breaking BC is a dangerous thing to do and not to be taken lightly when you
have a user base as massive as that of php.

in the mean time we have a faster 'execution model' to look forward to
in 5.1 - _faster_ OO code! yippee :-)

don't know if that is true - but then you don't say whether the machine your on
is running in safe_mode.

you don't even say what errors - why don't you present some output from your script,
no point in anyone running it somewhere else really is there?

******
oh and DONT post a new question as a reply to an existing thread - bad bad bad.
******

most probably your script (or rather the user it is running as - most likely something
like 'apache' else the user account given to you on the box in question) doesn't have
write permissions for the dir you want to move the upoaded files to.

or maybe the directory /release_pics/ doesn't even exist, $uploads_dir
need to contains path not a halfbaked URL - I'm assuming that your document root
is not / ... so try something like:

$uploads_dir = '/PATH/TO/YOUR/WEB/DOCUMENT/ROOT/release_pics/';

btw you have to replace the '/PATH/TO/YOUR/WEB/DOCUMENT/ROOT' bit with
something valid ;-)

oh and try checking the return values of functions (e.g. move_uploaded_file)
- they might give you a hint. also check your error logs and start using
functions like print_r(), var_dump() to see what's going on inside your script...

[snip]Can you place the following code just before the header() line,
and post what it prints?

die($this->CMS_base_path);

In other words, tell us what the $this->CMS_base_path field contains
when that line is executed.[/snip]

It contains 'https://cms.mydomain.com', which is what it is supposed to
contain.

It's redirecting to the correct domain, just the incorrect page.

attached mail follows:

[snip] I can think of a few, and my first instinct is to check to see
whether your script produces any errors in one environment that it
doesn't in the other. If you're displaying errors, they can affect the
behavior of your scripts when you're also using header(). Replace
header() with echo and compare the behavior.

Also, comparing php.ini can help you identify differences in
configuration. Configuration directives can be modified through other
means, but this is a good starting point (and a good candidate for
version control anyway - inconsistencies can cause you to waste time and
effort).[/snip]

Hi, Chris.

I turned on error reporting for that script in production and no errors
occurred.

However, and this is even stranger to me, if I add the following after
the call to header()

die('foo');

the page redirects to the correct url.

I remove die('foo'); and it redirects to itself again.

I'll take a look at the two ini files to see if I can spot any
differences, but I'm stumped as to what in there might cause just this
one page to redirect to itself rather than the prescribed URL.

The form submits to a controller url, and then is validated using a form
generation/validation class I use for all my applications. If the
validation fails it redirects back to the form page, with the
appropriate form id appended to the url. If the validation succeeds,
the delete event method is called, at the end of which the redirect back
to the main event page should occur, but is not for some reason, unless
I add that line of code after it.

I know the form is validating since the event is deleted, since, well,
it is deleted, and there is no form id appended to the url when it is
redirected.

Any other ideas?

Thanks,

Pablo
