Well I guess from my point of view there are several ways depending upon
the requirements.  Others that are better with OOP will chime in I'm sure.

This I'll get flamed for, but you can use one instance of core as a global:

class A extends framework_class {
  var $core;

  function A() {
$this-core = $GLOBALS['core'];
$this-core-go();
  }
}

//in global scope in bootstrap or whatever
$core = new core();

Along the same lines but more OOP and without globals, maybe use a
registry class and store core in the registry. This also uses one
instance of core:

class Registry {
protected $_objects = array();

function set($name, $object) {
$this-_objects[$name] = $object;
}

function get($name) {
return $this-_objects[$name];
}
}

class A extends framework_class {
  var $core;

  function A($registry) {  //dunno if you need a reference here or not
$this-core = $registry-get('core');
$this-core-go();
  }
  //i guess you could also pass in core, but registry will give you all
objects in the registry
  //function A(core) {
//$this-core = $core;
//$this-core-go();
  //}
}

//this is in your bootstrap or whatever
$core = new core();
$registry = new registry();
$registry-set('core', $core);

Or, if you don't need an object, call it statically:

class A extends framework_class {

  function A() {
core::go();
  }
}

Re: [PHP] Forms validation and creation- easier solution?

[Manuel Lemos]

Hello,

on 05/20/2009 11:09 AM Paul M Foster said the following:
 Both this class and Manuel Lemos' form generation class (from
 phpclasses.org) will create beautiful forms for you. However, you may
 find that the amount of [repetitive] typing you do will be equivalent or
 greater than simply creating the form by hand.
 
 The best solution would probably be a form you fill out which asks you
 about all the fields you want, and then generates the code to paint the
 form. There are commercial solutions which do this, and some (not that
 great) free solutions. I'm working on one myself, which will eventually
 be a sourceforge/freshmeat project.

Thank you for mentioning my package, but I am not sure what you mean.

The Forms Generation and Validation package seems to do exactly what you
describe and more.


IMHO, creating forms by hand is by no means simpler, especially if you
want to include browser side (Javascript) validation.

I mean, I am not masochist to create something that will give me more
work in the end to develop PHP forms based applications than if I would
type HTML manually.

Furthermore, the plug-ins that come with the package dramatically reduce
the amount of code you need to type to achieve the same generating
common HTML inputs manually.

Anyone can judge by yourself by going here and see several example forms
and the actual code that it takes to generate them:

http://www.meta-language.net/forms-examples.html

For instance this scaffolding plug-in generates CRUD forms that you
often need to manage data stored for instance in databases.

http://www.meta-language.net/forms-examples.html?example=test_scaffolding_input

For those interested to check it out, the actual class package can be
downloaded from here:

all features:

Re: [PHP] Shared memory - linx and PHP newbie

[Richard W]

Thanks Daniel for your suggestions.

What I have found are:
1) I'm assuming the key is good. A value of 1947143245 is returned.

2) I have set the permission of the shared memory (program.SCShared) to
777 octal (full read/write/execute access). The group and owner of the file
is my login ('eclipse'). According to the PHP manual for shmop_open(..), I
do not need to set the 'mode' parameter of this function (eg, to 0777)
because I'm trying to connect to an existing shared memory block. Despite
this, I've tried  setting mode=0777, but errors were generated when I ran
the code. I event tried changing the user and group to 'www-data' with no
luck.

3) I added the debug_backtrace and the display result was array(0) {}
inserted where debug_backtrace() was added as shown, but I'm not sure what
the result really means:

CODE

?php
$shm_key = ftok(/dev/shm/program.SCShared, 't');

var_dump(debug_backtrace());

if ($shm_key  0)
{
echo \nftok failed. Error message is $php_errormsg br;
}

$shm_id = shmop_open ($shm_key,w,0,0);

if ($shm_id == FALSE)
{
echo \n Shared memory doesnt exists br;
}
else
{
echo \n Shared memory exists br;
}

$shm_size = shmop_size ($shm_id);

var_dump(debug_backtrace());

echo \n the size of shared memory is $shm_size br;

$shm_data = shmop_read($shm_id, 0, 32);

if ($shm_data == FALSE)
{
echo \nCould not read data. : $php_errormsg br;
}
else
{
echo \nRead successful br;
}

echo \n read1 is $shm_data br;

$shm_data = unserialize($shm_data);

echo \n read2 is $shm_data br;

$i = strpos($shm_data, \0);

if ($i === FALSE)
{
echo \n String is NULL br;
}
else
{
$result = substr($shm_data, 0, $i);

print_r($result);

echo br;
}

shmop_close($shm_id);

echo \nDetached from shared memory;

?

=

===RESULT OF CODE
array(0) { } Shared memory exists
array(0) { } the size of shared memory is 1
Read successful
read1 is PHP_SM�'
read2 is
String is NULL
Detached from shared memory
=

4) The data I expecting to read is 9876.54321 because this is the first
string in memory. A 'cat' of the shared memory is shown:


r...@ts7800:shm# cat program.SCShared
9876.5432101.230034.50678.9010002345.678900

5)  Is there anything else that  can try?

Regards,
Richard.

  Any help will be greatly appreciated, especially answering 2) as to why I
  can't read the data.

Are you certain that the problem lies within the shmop reading?
 Check to see if the file is actually being accessed properly, the key
 is good from your ftok(), etc.  You may also want to make sure that
 things as basic as permissions and 'who created' vs. 'who can read'
 (since you're trying to run it from the web server) match up
 appropriately.

With just a cursory glance, the shmop_read() piece itself looks
 fine, which suggests to me that there may be other problems.  See if
 the logs spit anything out, or try to debug the things with an `or
 die(Here's the error.\n);` tacked onto the end of the suspected
 lines.  If it's crashing out, consider a cachegrind or
 debug_backtrace() run.

As for the memory being read, I'd agree that it does seem that it
 is, since shm_open() is returning something other than FALSE, but that
 doesn't mean that it's `=== TRUE` either.  It may instead be returning
 a message or another unexpected result that, in empty(), may evaluate
 to TRUE and allow it to echo out the message in your test condition.

Hi All,

are there any *disadvantages of setting session.auto_start to true in terms

[PHP] urgent CSS question

[PJ]

Sorry, but no one suggested a mailing list for CSS and the W3 Schools
Forum has problems.
This is the only reliable mailing list with professionals, so please
excuse my off-path question as it is rather urgent.

Why do I get completely different formatting with two identical classes?
I want to change part of the formatting on just one page on the site
using the exact same class with some changes so I don't modify other
pages. I copied div#frame to div#frame1 and changed the class on the
page to id=frame1. But now the page no longer displays the formatting
as with id=frame - e.g. p produces 16px font-size instead of 12px.

In general, I'd suggest creating page-specific style variations by 
sticking a class on the body (e.g. body class=article ) and using 
that as a hook to modify the styling of the class whose formatting you 
want to be different.


.thing {

That's not a very secure sudoers file.

But you probably don't want to use sudo to this anyway.

What you probably should do is write a shell script (IE w/ perl) that is 
suid root and executable by apache that adds the user to your system.


I don't know what your sudo error is, but have you looked at your sudo 
log file?


Make damn sure you validate the $username variable whatever solution you 
end up using.

Those are actually id names not class names, but it's not illegal in 
either case.


HTML id attributes must follow this:

http://www.w3.org/TR/html401/types.html#type-id

XML id attributes must follow this:

http://www.w3.org/TR/REC-xml/#NT-Name

The class attribute is a CDATA list:

http://www.w3.org/TR/html401/types.html#type-cdata

Pretty much the only thing illegal in a classname is whitespace.

You may be thinking of the restriction that HTML/XML id attributes may 
not /begin/ with a number.

Ok, I have duplicate classes - #frame and #frame1.
What I don't understand is why switching from #frame to #frame1 should
change formatting. The two classes are absolutely the same, the only
difference is the 1 in the name. I would logically assume that the
interpreter or whoever is operating this stuff would understand that the
page is using a different class, whether it is the same name as another
or not. If I create still another class and start to format the various
sections of that class, I will wind up with the identical class as
#frame1.  So where is the logic here? This is utterly incomprehesible
and seems to the the typical mess that we find in using CSS. It seems to
me that what I am trying to do is logically and intuitively clear and
simple.
I think you can see the implications of such confusion in creating a
different class - how can I rely on it doing what one would expect?

 In general, I'd suggest creating page-specific style variations by

Re: [PHP] urgent CSS question

On 22/5/09 13:27, PJ wrote:

Ok, I have duplicate classes - #frame and #frame1.


Let's get our terminology straight:

ids are not classes; classes are not ids.

ids look like:

id=thing

and are selected like:

#thing

classes look like:

class=thing other-thing

and are selected like

.thing

An element may have zero or one IDs.

An element may have zero or more classes.

id is supposed to be unique within a given document.

The same classname may be used multiple times in the same document.

See:

http://css.maxdesign.com.au/selectutorial/advanced_idclass.htm


What I don't understand is why switching from #frame to #frame1 should
change formatting.


#frame targets an element with id=frame while frame1 targets an 
element with id=frame1. So I'm not sure what these have to do with one 
another.



The two classes are absolutely the same, the only
difference is the 1 in the name.


Which is to say they are utterly different, since they have different names.


I would logically assume that the
interpreter or whoever is operating this stuff would understand that the
page is using a different class, whether it is the same name as another
or not.


I'm sorry, I don't know what you mean.


If I create still another class and start to format the various
sections of that class, I will wind up with the identical class as
#frame1.


Again, I don't know what you mean.


So where is the logic here?


Without seeing some clear test case links that reproduces the problem 
for us, I really can't comment about that.



It seems to me that what I am trying to do is logically and intuitively clear

 and simple.

What you're trying to do really isn't clear to me. Being able to see the 
problem (and the underlying code) might help.

i had a small misunderstanding regarding variable reference...now its clear

but..

the output of

?php
$x = 1;
$a1 = array($x);
var_dump($a1);
?

is
array(1) {
  [0]= int(1)
}

while for

?php
$x = 1;
$a1 = array($x);
var_dump($a1[0]);
?

it is

int(1)

can u tell me what  signifies here??

To get the results you expect, you should remove the  from the
assignment, as this is assigning by reference, rather than by value like
Shawn said, or use an  for $a2 as well.

it would be funny to change the root password! Needless to say, I added
a lot of safeguards into the both the PHP script and the Bash script to
protect the system users and enforce a strict naming policy on what was
allowed to change, so that only users in the form 'prefix_joebloggs',
'prefix_simon', etc were allowed. Luckily the system was all still in

 In general, I'd suggest creating page-specific style variations by 
 sticking a class on the body (e.g. body class=article ) and using 
 that as a hook to modify the styling of the class whose formatting you 
 want to be different.
 
 .thing {

 .article .thing {
  font-style: italic;

 for example.

That hook on the body tag is a good one, which I wish I'd thought of a
few weeks back! I've been using PHP to pull in external stylesheets
based on the current script name for a project I'm working on, as each
page has unique tweaks on common elements. It's not like I don't even
use selectors even now!

 Those are actually id names not class names, but it's not illegal in

 HTML id attributes must follow this:

 The class attribute is a CDATA list:

 Pretty much the only thing illegal in a classname is whitespace.
 
 You may be thinking of the restriction that HTML/XML id attributes may

There are certain bugs in IE that can cause problems with using what it
considers reserved words for ID's or class names. I've run into problems
before, particularly when using DXHTML (you know what I mean!) with
elements that had ID's called 'name', etc, even when referencing the
elements correctly with the getElementByID() DOM call. Also, I believe
there used to be a bug in IE (not sure what versions) where classnames
that were the same as ID's caused problems.

Re: [PHP] Forms validation and creation- easier solution?

 Hello,
 
 on 05/20/2009 11:09 AM Paul M Foster said the following:
  Both this class and Manuel Lemos' form generation class (from
  phpclasses.org) will create beautiful forms for you. However, you may
  find that the amount of [repetitive] typing you do will be equivalent or
  greater than simply creating the form by hand.
 
  The best solution would probably be a form you fill out which asks you
  about all the fields you want, and then generates the code to paint the
  form. There are commercial solutions which do this, and some (not that
  great) free solutions. I'm working on one myself, which will eventually
  be a sourceforge/freshmeat project.
 
 Thank you for mentioning my package, but I am not sure what you mean.
 
 The Forms Generation and Validation package seems to do exactly what you
 describe and more.
 
 
 IMHO, creating forms by hand is by no means simpler, especially if you
 want to include browser side (Javascript) validation.
 
 I mean, I am not masochist to create something that will give me more
 work in the end to develop PHP forms based applications than if I would
 type HTML manually.
 
 Furthermore, the plug-ins that come with the package dramatically reduce
 the amount of code you need to type to achieve the same generating
 common HTML inputs manually.
 
 Anyone can judge by yourself by going here and see several example forms
 and the actual code that it takes to generate them:
 
 http://www.meta-language.net/forms-examples.html
 
 For instance this scaffolding plug-in generates CRUD forms that you
 often need to manage data stored for instance in databases.
 
 http://www.meta-language.net/forms-examples.html?example=test_scaffolding_input
 
 For those interested to check it out, the actual class package can be
 downloaded from here:
 
 http://www.phpclasses.org/formsgeneration
 
 Here you may watch an extensive tutorial video that covers practically
 all features:
 
 http://www.phpclasses.org/browse/video/1/package/1.html
 


Here's what I was talking about. Assuming you simply type out your form
fields like this:

input type=text name=address size=30 value=123 Main St./

Now, if you do it with a class like yours:

$arr = array('type' = 'text',
'name' = 'address',
'size' = 30,
'value' = '123 Main St.');

$form-AddInput($arr);

(I haven't looked at your class in a while, so I may have invoked it
slightly incorrectly.)

If you compare the typing involved in the first case with the typing
involved in the second case, you can see that it's more in the second
case.

Yes, your forms generation class includes a tremendous amount of proven
code, including a bunch of Javascript validation, all of which the
programmer doesn't have to develop himself.

The only real complaint I have about your class is that the class file
itself (forms.php) is 158+ K bytes, which must be loaded every time you
surf to a page for the first time.

[PHP] DOM Source of Selection

Hi

I am working on a project wherein i have to extract information from a
webpage and use it for processing. However that information becomes
available only when i manually select a part of the webpage and view its
source information (DOM source of selection ). Now i want this to be
automated . Is there any way in PHP by which i can directly refer to that
particular DOM and load its source , say directly into a variable .

Bottom line is when using a public list, if you don't want your e-mail 
address to be public you use something like yahoo or gmail for the list 
mail.


Spam bots can and do subscribe to public lists to harvest e-mail 
addresses, if you are subscribed to a popular public list the spambots 
have your e-mail. That's just the way of things.

They executed someone for this and still voted Bush in? Sheesh!

I've never had any problems with ending classes with numbers, actually
using it on a site at the moment that highlights keywords, by enclosing
said words within span class=highlightx tags, where x is a number.
No bugs in any browsers we've tested: IE, Fx, Opera, Safari, Chrome,
Konqueror.

In the first instance you are var_dumping the entire array so it shows

specific var so you get the value of the var int(1).  I'm not sure if
there is a reason that it doesn't show that it is a reference, but the
same is true here:

$x = 1;

var_dump($y);

[PHP] IE can't download, FF can: SSL ? Need special headers?

[Dee Ayy]

The following code has been working for about 6 years.  The only
change I am aware of is that now it is being served from a server
requiring SSL to access it.

header(Content-type: $type);
header(Content-length: $size);
header(Content-Disposition: attachment; filename=\$name\);
echo $data;

It still works in FF, so I assume the variables are being filled in.
For example:
header(Content-type: application/pdf);
header(Content-length: 75485);
header(Content-Disposition: attachment; filename=\test.pdf\);

In DebugBar HTTP(S) after the GET request which had to be authorized
by htaccess it reports:

Content-Type: application/pdf

Should HTTP/1.1 200 OK be HTTPS/1.1 200 OK?  If so, how can I get
that set?  Is there some funky header I need?

Oh, the IE 7 error is:
Internet Explorer cannot download my_php_file.php?a_name=a_value from
my.site.com.

Internet Explorer was not able to open this Internet site.  The
requested site is either unavailable or cannot be
found.  Please try again later.

FYI: If the user cannot choose a filename to save as, it gets saved as
my_php_file.php which needs to be renamed to extension .pdf to be
viewed in a PDF viewer.
So if you have any helpful headers to force the filename, I'd
appreciate that too.  Apparently Content-Disposition: attachment;
filename=test.pdf doesn't work (on FF and maybe other browsers).

There is an issue with Internet Explorer 6

I'm not sure about IE7 specifically, but IE is touchy about
downloading documents - especially PDFs. Here are a few things I keep
in mind that have worked so far:

For all browsers, we send the following headers (which you appear to
be setting):
- Content-Type with the correct MIME type
- Content-Disposition as attachment with the file name. I have found
that the filename should be urlencoded to prevent problems with the
file name not being recognized by the browser.
- Content-Length
- Content-Transfer-Encoding: binary

For MSIE, identified by user-agent* we also add cache control since IE
has a problem handling PDF documents when the headers direct it to not
cache the document:
- Expires: date('r', strtotime('+3 hours'))
- Cache-Control: max-age=60
- Pragma: public

* Yes, I know user-agent isn't very reliable, but generally it won't
hurt other browsers if these headers are added to someone who happens
to be spoofing IE.

This has worked pretty well for us so far, and these are being served
via SSL. (Not that they need to be, since they are just blank forms,
but it prevents warnings since the rest of the site is SSL.)

From what I can tell, IE has a problem with PDFs that are not cached.
It seems that to handle the documents, it saves a copy in the temp
folder and then directs Adobe to open that file when it spawns the
reader. When you tell IE not to cache the document, it dutifully
obliges, but it still tells Adobe to open the file from the temp
folder. At least, that's what it looks like it tries to do.


To get around the filename problems, you could also use some sort of
mod_rewrite where the URL requested is the actual PDF name but let PHP
handle the request if the above doesn't work for you.

Why are you saving the file first as PHP and then renaming to PDF?
Below is the code that I use (which uses the DOMPDF class from

it and forces a download if IE

$dompdf = new DOMPDF();
$dompdf-load_html($html);
$dompdf-render();

// The next call will store the entire PDF as a string in $pdf

  $pdf = $dompdf-output();

// You can now write $pdf to disk, store it in a database or stream it
// to the client.

//check if IE,since it doesn't like the stream, so we save it to disk and

  $browserCheck = browserDetection();

[PHP] Legal $_SESSION names

[tedd]

Hi gang:

While we're discussing what's legal in css, here's a couple of things 
I've found about sessions.


I found that starting a session with a number doesn't work.

$myvar = $_SESSION['1myvar'];

I also found that dumping a session to a variable with the same name 
may cause problems, such as:


$myvar = $_SESSION['myvar'];

Regardless of what anyone may say to the contrary, it doesn't work 
everywhere. I found that out the hard way. The fix is simply to use a 
different name for the variable, such as:


$my_var = $_SESSION['myvar'];

Hopes this help someone.

Cheers,

tedd

The second case won't work if you have register globals turned on I
believe, as it will attempt to create $_SESSION['myvar'] as $myvar. I
believe that RG might have something to do with the first as well. I
seem to remember a thread a while back talking about sessions not being
able to use numbered indexes because they are a special super global.

The second case won't work if you have register globals turned on I
believe, as it will attempt to create $_SESSION['myvar'] as $myvar. I
believe that RG might have something to do with the first as well. I
seem to remember a thread a while back talking about sessions not being
able to use numbered indexes because they are a special super global.

You are right, but here's the rub -- when you have register globals 
turned on and you use:


$myvar = $_SESSION['myvar'];

This sometimes works and sometimes fails. I had an entire site where 
I had been using the same names for attributes and variables 
throughout and suddenly one page didn't work. All other pages worked 
just fine, but this single page didn't.


I searched high and low for an answer and found a vague reference 
where someone else had run into a similar problem and found the 
solution was to change the variable name. So I did with that single 
page and everything worked.


Why did that single page not work and everything else did? I haven't 
a clue, but I will say that I reduced the problem to that 
specifically and that *was* the problem.


Additionally, why was that problem not realized in the other pages on 
the same site -- I don't know, but this was an example of sometimes 
it works, and sometimes it doesn't -- a heck of a way to run a 
railroad.

Re: [PHP] IE can't download, FF can: SSL ? Need special headers?

[Dee Ayy]

I went with this, modified from http://php.he.net/readfile docs example 1:

header('Content-Description: File Transfer');
header('Content-Type: '.$type);
header('Content-Disposition: attachment; filename='.basename($name));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: '.$size);
echo $data;

And it works in FF 3.0.10 and IE 7 and Safari 3.2.1.
I thought it would be some header magic.



Bastien,
I think because I was not urlencoding or not basenaming the filename,
it would come through as the name of the script if the name had a
space in it.  test.pdf actually came through with the name test.pdf.
But the real filenames are like QUOTE Part 1-2 Prospect Name.pdf.

Thanks everybody.

I was looking up those other header names and case sensitivity when I
found the readfile example.  DebugBar reports a different case than
what I sent, so I thought that could be an issue too (like
Content-Length versus Content-length).  Moot for me now though.

Re-RTFM I guess.

Regards.

Re: [PHP] IE can't download, FF can: SSL ? Need special headers?

[Dee Ayy]

Acceptable results, but could be better.

basename works correctly for only Safari (filenames with spaces are correct).
FF truncates the name starting with the first space.
IE puts an underscore in place of a space.

urlencode puts a plus sign in place of a space for all 3 browsers.

But I've always had a note telling the user to rename the file to
something useful, so I'll keep basename and not check the agent.

Thoughts?

Find the Computed Style and how it was inherited (cascaded).

In Internet Explorer, use DebugBar.

Good one.

Put it back on me rather than the browser developers.

But that's in line with my requesting the user to use underscores.
I'll implement this str_replace.  Thanks.

 I've asked the user to use underscores, but they really shouldn't have
 to.  Safari gets it right.
 
I've found that

header(Content-Disposition: attachment; filename=\$filename\);

seems to work for me

note, that's untested as i wrote it there, but i had a similar problem
at work and found that enclosing the filename in double quotes worked
for all the browsers i tested on.

 On 22/5/09 13:27, PJ wrote:
 Ok, I have duplicate classes - #frame and #frame1.

 Let's get our terminology straight:

 ids are not classes; classes are not ids.

 ids look like:

 id=thing

 and are selected like:

 #thing

 classes look like:

 class=thing other-thing

 and are selected like

 .thing

 An element may have zero or one IDs.

 An element may have zero or more classes.

 id is supposed to be unique within a given document.

 The same classname may be used multiple times in the same document.

 See:

 http://css.maxdesign.com.au/selectutorial/advanced_idclass.htm

 What I don't understand is why switching from #frame to #frame1 should
 change formatting.

 #frame targets an element with id=frame while frame1 targets an
 element with id=frame1. So I'm not sure what these have to do with
 one another.

 The two classes are absolutely the same, the only
 difference is the 1 in the name.

 Which is to say they are utterly different, since they have different
 names.

They may have different names, but does that change their functionality?
They are identical except for the 1 in the title of the id. So, if I
change the one id to the other in the same code, I don't understand why
the formatting would change? Obviously, the parents and the children
have not changed unless there's some weird hanky-panky going on.
The simple reason to change the id is to avoid messing up the appearance
of other pages that are using the same css file. Or do I have to make a
new css file for every page; that would be a little ridiculous, wouldn't
it? And to follow the logic here, if I create a different id and in the
end it turns out to be identical to the original frame except for the
name, shouldn't it function the same.
There is no need to see sample code because the code does not change THE
ONLY THING THAT IS CHANGED IS THE ID NAME ! and, I mean only the name...
the only plausible explanation would be the change within the css file
and that implies that there is something funny going on within that
file. Or are there unseen elements being kept alive when there is a
change in the nomenclature of the id?
Or does the browser keep things in memory or are the memory modules
having neuron crises?
As I have stated before, this is the kind of thing that drives one crazy
trying to understand the un-understandable.
 I would logically assume that the
 interpreter or whoever is operating this stuff would understand that the
 page is using a different class, whether it is the same name as another
 or not.

 I'm sorry, I don't know what you mean.

 If I create still another class and start to format the various
 sections of that class, I will wind up with the identical class as
 #frame1.

 Again, I don't know what you mean.

 So where is the logic here?

 Without seeing some clear test case links that reproduces the problem
 for us, I really can't comment about that.

 It seems to me that what I am trying to do is logically and
 intuitively clear
  and simple.

 What you're trying to do really isn't clear to me. Being able to see
 the problem (and the underlying code) might help.

[PHP] Rogue 'if - elseif' code

[Andre Dubuc]

Hi,

I'm having problems with a chunk of 'rogue' code that does not perform as 
expected (it does not pass the expected date, but an empty value). Most of 
the time, it works - so I'm wondering whether it might be a browser issue. 
(The latest failure occurred with Firfeox 3.0 browser on an NT 5.1 OS.) The 
code is stored on an Unix server, running PHP 5.x. 

I've isolated it down to multiple if - elseif statements that check long dates 
for completeness, day month and year. The code then applies it results 
printing one of following: the full date - 22 May 2009, month-year - May 
2009, or just the year, 2009. My question is whether the ORDER of checking is 
important, i.e, whether checking for the null sets BEFORE full sets or AFTER. 

I've added debugging code to be able to get the raw POST values so I can 
manually enter it into the db, but I would really appreciate some help here. 
The code is old -- I wrote it seven years ago, and had worked well until I 
modified it, but I no longer have the original working code. 

[The first conditional line of the code checks whether the user has entered 
the birth date, then it checks for the death date. The $_SESSION stuff is 
debugging code.]


?php


$yd = $_POST['death'];
$yb =  $_POST['birth']; 


if ($_POST['bday'] == Day  $_POST['bmonth'] == Month

That depends on:

1) The contents of your CSS file, which I can't see.
2) Whether you've made any errors when modifying your HTML, which I 
can't see either.

Re: [PHP] Forms validation and creation- easier solution?

[Manuel Lemos]

Viva,

on 05/22/2009 10:36 AM Paul M Foster said the following:
 IMHO, creating forms by hand is by no means simpler, especially if you
 want to include browser side (Javascript) validation.

 I mean, I am not masochist to create something that will give me more
 work in the end to develop PHP forms based applications than if I would
 type HTML manually.

 Furthermore, the plug-ins that come with the package dramatically reduce
 the amount of code you need to type to achieve the same generating
 common HTML inputs manually.

 Anyone can judge by yourself by going here and see several example forms
 and the actual code that it takes to generate them:

 http://www.meta-language.net/forms-examples.html

 For instance this scaffolding plug-in generates CRUD forms that you
 often need to manage data stored for instance in databases.

 http://www.meta-language.net/forms-examples.html?example=test_scaffolding_input

 For those interested to check it out, the actual class package can be
 downloaded from here:

 http://www.phpclasses.org/formsgeneration

 Here you may watch an extensive tutorial video that covers practically
 all features:

 http://www.phpclasses.org/browse/video/1/package/1.html

 
 
 Here's what I was talking about. Assuming you simply type out your form
 fields like this:
 
 input type=text name=address size=30 value=123 Main St./
 
 Now, if you do it with a class like yours:
 
 $arr = array('type' = 'text',
 'name' = 'address',
 'size' = 30,
 'value' = '123 Main St.');
 
 $form-AddInput($arr);
 
 (I haven't looked at your class in a while, so I may have invoked it
 slightly incorrectly.)
 
 If you compare the typing involved in the first case with the typing
 involved in the second case, you can see that it's more in the second
 case.

That is because you are just thinking about the typing of the generated
HTML. To generate and validate forms, you also have to consider the code
you write to validate and process the forms because the HTML forms do
not process by themselves.

You need to think about the security of your application, so you also
need to validate submitted values, discard invalid values, escape
outputted values, and so on. All that is done with a couple of calls to
the forms class.


 Yes, your forms generation class includes a tremendous amount of proven
 code, including a bunch of Javascript validation, all of which the
 programmer doesn't have to develop himself.
 
 The only real complaint I have about your class is that the class file
 itself (forms.php) is 158+ K bytes, which must be loaded every time you
 surf to a page for the first time.

That used to be an issue in the 20th century in the PHP 3 days. Since
PHP 4, the PHP code is no longer interpreted. The Zend engine compiles
the PHP code in Zend op codes in the first stage. In the second stage
the op codes are executed. If you use a cache extension like APC, Turck
MMCache, XCache, etc.. the first step is skipped after the first
execution and the size of the original code is not relevant because it
is already compiled in shared memory.

Anyway, the class has all that code because it is necessary to implement
all it supports.

implementing forms.


This is fairly simple to roll-your-own.

I do it from metadata. I check MySQL metadata for data types,  
lengths, and defaults. In addition, my metadata tables contain:

 -- field captions
 -- field-use descriptions and business rules (generates CSS pop-up  
help)

 -- the type of control used
 -- the source of data for controls (I call system codes: like the  
lists of choices for comboboxes and radio buttons -- I keep almost  
all of these in a single table.)

 -- whether data in a field is required
 -- whether the data in a field are visible, editable, or new-record- 
only editable
 -- whether the data are encrypted (core data class handles the  
encryption/decryption)

 -- data entry order
 -- any non-standard user rights to the data.
 -- Simple business rules (like maximums, minimums and ranges of  
acceptable values)
 -- easy validation categories: birthdates, eMail formatting, USA  
phone numbers  postal codes, US social security #'s, credit card  
format, and the like.


The last two can generate JavaScript, too (still working on that).

 -- I also am working on more complex validation being automatic:  
across fields or tables, dependent on other variables, etc.


By standardizing the format of metadata and the means of storing  
system code values, plus core CSS class names, you can use this  
across projects.

Ok, I'm glad the there are some people out there  who want to get down
to the bottom of things.
I can attach or maybe put up a link on a website where you can look at
the code and the css.
But regardless of any test caste, nothing changes the fact that whatever
the html code, whatever the php code, these are sonstant and nothing is
changed. Switch between id frame and id frame1 and things change.
nothnig, I meant, nothing is changed in between. The difference is in
the css, and nothing else.
I'll post the location later tonight or , more likely, tomorrow am.

 Please help me. I need your help.
 Thanks and regards.
 
 That's not a very secure sudoers file.
 
 But you probably don't want to use sudo to this anyway.
 
 What you probably should do is write a shell script (IE w/ perl) that is 
 suid root and executable by apache that adds the user to your system.
 
 I don't know what your sudo error is, but have you looked at your sudo 
 log file?
 
 Make damn sure you validate the $username variable whatever solution you 
 end up using.

Yeah I know my script don't care at all about security. I'm keeping it fot
the sake of simplicity.
After making it 'work', I will take a look seriously about security.
So, why it not create user for me?
thanks and regards

I'm not that familiar with sudo, but I suspect it may have to do with 
the fact apache is a user without a shell.


look in the sudo log file.
If you don't see anything, look in /var/log/secure and /var/log/messages 
and /var/log/httpd/error_log


If you don't see the problem, log into a root shell. Then run

su apache

to become the apache user and try the command and see what happens.

Really though, this isn't a job for sudo.
It's a job for a suid root shell script (I'd suggest perl or python or 
maybe tcl/expect).

[PHP] How to assign eval() to variable?

[Afan Pasalic]

hi,
I have on one website boxes with information, pulled from mysql. the 
content can be string, php code, url of other website or url to specific 
file etc.


currently, I have something like this:

// connect to db
// mysql_query() to get box content and content_type

switch($content_type)
{
  case 'string':
 echo $content;
 break;

  case 'php_code':
 eval($content);
 break;

  case 'website':
 echo 'iframe'.$content.'/iframe;
 break;

  case 'file'
 require_once($file);
 echo $file_content;

  // etc.
}

but, now I have to change the code to assign content to variable and the 
variable will be printed later. I tried something like this:



switch($content_type)
{
  case 'string':
 $record = $content;
 break;

  case 'php_code':
 $record = eval($content);
 break;

  case 'website':
 $record = 'iframe'.$content.'/iframe;
 break;

  case 'file'
 require_once($file);
 $record = $file_content;

  // etc.
}

and it works - except eval() part. cant do $record = eval($content); 
?!?!?!?


thanks
