Obtain a backtrace of the program (assuming your on unix):
Run gdb with php as the program:
> gdb /path/to/php
when the gdb prompt somes up type the word 'run' with the options
and filename you would normally would pass to php:
(gdb) run [options] phpfile.php
Once it finishes with your crash then type 'bt':
(gdb) bt

Hi all,
I am wondering what would be the best way to handle checkboxes. I am
making a site that will display several items in a 20-items-per-page
format and each item will have a checkbox next to it for the user to
select them. Now, what I need to do is to record the items selected by
the user when clicking the “Next button” into a MySQL table. Should I
name all the checkboxes the same, using the item IDs as values and then
use an array to see which ones where selected or maybe another thing?
Thanks in advanced,
Cesar Aracena

You could try this:
<input type="hidden" name="box1" value="0">
<input type="checkbox" name="box1" value="1">
So basically when it get submitted, you'll have either a 0 or 1 response
to know whether or not it has been checked.
Does this help?

It could be a solution but only working with a few items. My list(s)
will be filled up with hundreds of items grabbed automatically out of
another MySQL table... would it help too? Maybe naming the checkboxes
with each item own ID... anyone?

I think I'd just use like
<input type="checkbox" name=box[1] value=1>
<input type="checkbox" name=box[2] value=1>
<input type="checkbox" name=box[3] value=1>
<input type="checkbox" name=box[4] value=1>
then you can loop through it with foreach($_POST[box] as $BoxID => $Value)
.. I assume the recieving script knows what boxes it expects?

You could name them as:
<input type="checkbox" name="choice[]" value="1">
<input type="checkbox" name="choice[]" value="2">
etc...
Then $_POST['choice'] will be an array of the boxes chosen.
$list = implode(',',$_POST['choice']);
will give you a comma separated list of all items chosen.

What you could do is this:
$query = "SELECT field_name FROM table"
$result = mysql( $dbname, $query );
while( $dataRow = mysql_fetch_assoc( $result )) {
echo '<input type="checkbox"
name=checkboxes[]
value="' . $dataRow['field_name'] . '">';
}
On submission, all your checboxes will be here:
$_POST['checkboxes']
and you can iterate through that to see what fields/checkboxes
were set. No fuss, no muss and no billion if( isset( $checkbox )).

ASP doesn't do an upload meter by magic. PHP can do anything ASP can

So true.. I use PHP a lot to dynamically generate DHTML and JScript,
which of course are tied to ways to get data back to PHP from
jscript/dhtml results. My latest project is dynamically generating "cool
menus" using Thomas Brattli's Coolmenus library (jscript/dhtml) with PHP
and database results.
A while back, out of sheer boredom, I wrote a PHP script which
dynamically generates a PHP script using database results, saves it to a
database, and then
"grabs" and executes the new script. I havent used that for anything
except playing around and burning time/killing boredom. However, I also
have a PHP program which you can run and edit the source code for the
program inside the program itself, hit render and all of a sudden you
are running the new version of the program. It is so cool that it is
just plain sick. I use this methodology all the time - every day,
everyone loves it, and my fridge has good food in it as a result. My
point is that nothing is impossible, it is all just a matter of how you
perceive things and how you react to these perceptions. Free your mind
and the paychecks will follow, not to mention good code will just flow
from your fingertips. :)

Basically it is just a lean and mean content editor I wrote that saves
anything (html, php, yada yada-you-name-it) to a database. I use it
inside an "environment framework" system I created which controls
logging in and using the editor. So you go to the 'site', log in, and
then you can run the editor and whatever other apps you have been given
user-level access to. Your access level also determines what content
you can access. Low level access users can edit only their own
content. "Super elite" users can view/edit all content of all users,
and as well can edit the HTML/PHP, etc. of the site itself. As "super
user elite", you can also select the content editor and edit the source
code (PHP) of the content editor. Really, you can edit any application
that is inside the environment framework system. ...hmmm.. Based on a
setting defined for each peice of content in the database, when you
click 'render', some PHP files may be written to a specified file system
while other content 'chunks' stay in the database and never rendered out
as files. These chunk files can but do not contain PHP... this is used
for just content or referencing actual content chunks.. so I created a
very basic macro psuedo language using PHP.. I call it metaChunk but I
imagine the name may already be taken, otherwise this email acts as my
copyright to that name according to the Berne Copyright convention. :)
LOL ... An example of a content 'chunk' as seen in the editor (just an
example that does not *really* exist - just typing junk from my head
that would parse):
<b>Hello !!$:varuser!!<b><br>
You have logged in !!$:logins!! times<br><br>
!!displayChunk:menu.js!!
!!displayChunk:userscreen!!
!!includefile:funk.php!!
The output is of course an HTML document that the end-user sees in ye
olde browser.
This is all a couple of years old and since then I have found others
that have developed similar things.. lots of CMS systems and macro
languages..... someone said my metaChunk psuedo lang looks like
"struts", which I have yet to see for myself or bother to read about.
So Chunks can include and run PHP, display and render other chunks, and
display variables. One day I may expand it. I'd like to release all
this to open source but I just cant afford to do that yet, and a
contract with my employer is another deterent. I am guessing others out
there are in the same boat. I have been PHP'ing since late 98 but
working on this stuff specifically since 2k. In my 3 years of
developing this stuff, I have made a point to not examine open source
code so as to keep everything 'original'. I am just an old school
programmer/ex hacker from the 80's that refuses to rip others off as I
have already been ripped off a time or two in the past both in the music
biz and the technology biz, including *major* media companies to say the
least....
If you were to put <? echo "Hello, World!"; ?> inside the database as a
content 'chunk', it will just display the PHP to the web-browser instead
of actually executing the code. All in all this whole deal just makes
my life easier since I dont need my users being able to exec any code.
Just FYI, this project started in late 2000 after my return from Los
Angeles where I was recording at Paramount. I bought a Commodore 64 SX
at a yard sale for $5.00 US. I got a copy of CNET 10.0 BBS out of a
dusty old box and set it up for fun. It became my reference point for
the first few months to create a BBS like system for the web which was
similar to the old days of BBS, unlike the majority of BBS type systems
on the web today. Just trying to be unique and different in my own
old-school way. I blab about all of this vaguely at my doomstar.com
site, which implements these tools and my employer is also allowing me
to reuse my codeBase in applications I develop for their clients.
Note to all: please send private replies as any further discussion
could quickly become 'off topic' for the php-general list. I am
interested in meeting other like minded people whom already know how to
code and just want to throw ideas around for fun and inspiration.
Thanks for you interest in my work! It is greatly appreciated.

try java scripts, there is a function called "onChange()", you can attach
this
with your combo box and can submit (SELF) the form upon the content change
in
combobox.
I have done this long time back, i'll send you the coding if still i have

Thank you. I did the following:
if (isset($_POST[MI]) && (preg_match('/^[[:alpha:]]{1,1}$/', $_POST[MI]) == 0))
and zero is caught.

I believe I spoke too soon. If I use isset() then even if I leave the
field empty it still returns true. I am trying to view the documentation for
this function but php.net seems to be timing out now.

That is because the browser is sending in the POST data:
MI=
Thus, php does set it to ''.
Use something like this instead:
if (strlen($_POST['MI'])) ...
btw, you should really quote your array keys.

Most of my program functions use the first approach
I have what ever must be given because the nature of the functions only
exists because it does certain things.
I then have the last argurment passed be an array. This will contain all
the data that I might want to use inside the function other then the
required fields.
for example I have a 'BOXTOP()' and 'BOXBOTTOM()' function set.
for the 'BOXTOP()' function I require the first argument but after that is
an array.
with this, I can customize the with of my box and if it isn't given it
defaults to a predefined with.
I can do the same thing with themes, colors, borders, cellpadding,
cellspacing, etc...
Then it will pass this same information to the corresponding 'BOXBOTTOM()'
function.
This keeps things very nice and clean.
inside the 'BOXTOP()' function is a mess, but once it is how you want it,
you will find that it is very easy to work with functions formated like
this.

hi,
Are you sure the data is posted from HTML
through POST ? try adding the lines below:

if(is_array($HTTP_POST_VARS) && !empty($HTTP_POST_VARS )) {

$_POST;
Also it is now a superglobal in php 4.3 and doesn't need to be
global'ed inside of functions.

btw! if you use it inside a function, you need
to declare it as global!

Hi,
I have a form with checkboxes that POSTs to a PHP script.
What is posted [ from phpinfo() ]:
_POST["color-1"] on
_POST["color-4"] on
_POST["color-6"] on
Parser:
foreach($_POST as $ThisVar=>$ThisVal){
if(ereg("color-", $ThisVar) AND $ThisVal=="on" OR $ThisVal==1){
$newVarA=explode("-", $ThisVar);
$colors.="$newVarA[1]:";
}
}
Expected Output:
$colors="1:4:6:";
Real Output:
$colors=":1:4:6:";
I can work with the output I am getting, however, I am curious why I am
not getting the "expected output". Can anyone shed light on this? I am
using PHP 4.3.2 compiled under a unix environment. Is this a bug in
ereg or am I just not seeing something obvious in my foreach?
Thanks,
Kris

Just an addendum.. My parser has $colors=""; right before the foreach
loop.

Do you have anything else in _POST that's equal to 1? I didn't look up
order of operation, so I may be off here, but your if condition might not be
doing what you are expecting. Try using parentheses to group it like this
if(ereg("color-", $ThisVar) AND ($ThisVal=="on" OR $ThisVal==1)){ (I'm
guessing that's what you want). Why are you using ereg anyway? You're not
using a regular expression so strstr would work just as well and be slightly
faster.

There is more post data than this.

Your logic, as jennifer pointed, isn't probably what your
expecting. You're POST data has a value of 1 somewhere.
Also, ereg is very expensive for doing exact string matches like
you are doing there, best to use the str* functions avaible to do
tasks like this. ie:
if ('color-' == substr($ThisVar, 0, 6))
And then no need to explode into an array and then extract the
value (more overhead).. since the format is known you can do
something like:
$colors .= substr($ThisVar, 6);
HTH,
Curt

You have POST var with value of 1 somewhere before.

Hope I can be of any help again .. what you are doing seems rather
complicated... what if you have your checkboxes like:
<input type=checkbox name="checkbox[colors][1]" value="on">
<input type=checkbox name="checkbox[colors][4]" value="on">
<input type=checkbox name="checkbox[colors][6]" value="on">
and the recieving script just doing:
if (isset($_POST['colors']) && is_array($_POST['colors'])) $colors =
join(':', $_POST['colors']);
PHP will only register indexes in the $_POST['colors'] array for the boxes
that are checked, all your colors are in one array, so one simple join would
do the trick .. won't it? The if in front of it is just to prevent any
"undefined index" notices .. might you have E_ALL set as error level.
.. wait .. getting a message .. yeah, there's a better way
$colors = (isset($_POST['colors']) && is_array($_POST['colors'])) ? $colors
= join(':', $_POST['colors']) : '';
now your $colors variable will always be set with a string value.
Grtz,
Wouter
Ps. anybody knows when syntax highlighting is gonna be an option in MS
Outlook? Would be neat, wouldn't it?

Hi,
I’m coding a function that will create a set of directories using
execution of shell commands within the function. Then the function saves
different sizes of images in each directory. Later in the function I
open one of these directories to list the content in them. The problem
is that the directoris don’t exist when the function is trying to list
the content in them. When I execute the function again with exactly the
same parameters there is no problem, then the directories exist!
I’m thinking that the shell commands are somehow set in some kind of
buffer or queue and are not executed until the rest of the php code is
executed?
Could this be true? If anyone has anything to say on this I’d appreciate
it.
BTW I'm using RH8.0 and PHP 4.2.2

$news is not valid, therefore your query failed. Use mysql_error() to
find out why.

Hi
I just want to ask if I have to translate this expression: struct stat
in:
<structfield>sb</structfield> is a regular, system defined, struct stat.
Apparently, it is not translatable and I was asked to no do it; but some
translators did it: for ex. the French translation.
So, please do I have to translate it or keep it like it is?
and if it is translatable, does this expression mean: structure statistics ?
and is "struct stat" a file ?
Regards
Hafid

Hi,
I'm translating the file / chapters / streams.common.xml and I'm facing some
problems so I need some help please:
1. "memory mapped files"
I don't understand the meaning of this expression, so I can just make a
temporary translation in this moment. I need to know the meaning or function
of these files. Is this meaning right > "the files which memory is mapped?"
2. I ask you to simplify your texts. I remarked that I affronted the same
problem with other groups when translating like French and Spanish groups.
Example: How would you express this sentence in a simple way:
<function>php_stream_copy_to_mem</function> allocates a buffer
<parameter>maxlen</parameter>+1 bytes in length using
<function>pemalloc</function> (passing <parameter>persistent</parameter>).
The difficulty is here: a buffer <parameter>maxlen</parameter>+1 bytes in
length
Do you mean: maxlen buffer or buffer maxlen ????

hello,
you can use the split() method to break this up into pieces. Unless you
are doing a large number of inserts on tables with several keys mysql
will not be troubled too much by the number of queries you run.

Maybe you should be using the LOAD_FILE() function in your query?
Quote:
LOAD_FILE(file_name)
Reads the file and returns the file contents as a string. The file
must be on the server, you must specify the full pathname to the file,
and you must have the FILE privilege. The file must be readable by all
and be smaller than max_allowed_packet. If the file doesn't exist or
can't be read due to one of the above reasons, the function returns NULL:
mysql> UPDATE tbl_name
SET blob_column=LOAD_FILE("/tmp/picture")
WHERE id=1;
