Re: [PHP] included file var scope
In index.php rather than declaring vars like so... $var = 'value'; ...declare them in the $GLOBALS array like so... $GLOBALS['var'] = 'value'; $var is then in the global scope regardless of where it was set. -Stut That would work. However I'm looking for a more generic solution, independent of the system that is being included. So basically I want to be able to include a file in my function while stepping out of the context of the function itself. E put all those variables in a singleton. then just use MyGlobals::getInstance()-myvar all over the place and you can do whatever you want with them. of course don't forget to include the class definition everywhere you want to use it greets, Zoltán Németh -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

why not? you would use 2 sql queries while I would use one most of the
time and 2 in case of already reserved ID - that is almost twice as much
processor time
that may count much if the routine is used frequently
Go ahead, try it, and tell me how much time it cost.
From experience, there are things one can spend
their time optimizing and there are other things
that one should be able to see that aren't worth

I've been wrong before, but you're open to prove me wrong again, if you like.
okay, I've got up earlier and made a little benchmark. The result
suprised me, and proved you right. ;)
here is the code:
?php
$db = mysql_connect(localhost, testuser, test);
mysql_select_db(testdb);
// method 1
$time = microtime(TRUE);
for ($i = 1; $i = 5000; $i++) {
$done = FALSE;
while (!$done) {
$id = md5((microtime(TRUE) * (rand(1,1000) / 100)));
$sql = SELECT * FROM idtest WHERE id='$id';
$result = mysql_query($sql);
if (!($row = mysql_fetch_array($result))) { $done = TRUE; }
}
$sql = INSERT INTO idtest (id,cnt) VALUES ('$id', $i);
mysql_query($sql);
}
$end = microtime(TRUE) - $time;
echo method 1 time: . $end . br;
// clean up table
$sql = DELETE FROM idtest;
mysql_query($sql);
// method 2
$time = microtime(TRUE);
for ($i = 1; $i = 5000; $i++) {
$done = FALSE;
while (!$done) {
$id = md5((microtime(TRUE) * (rand(1,1000) / 100)));
$sql = INSERT INTO idtest (id,cnt) VALUES ('$id', $i);
$result = mysql_query($sql);
if ($result) { $done = TRUE; }
}
}
$end = microtime(TRUE) - $time;
echo method 2 time: . $end . br;
?
and the output:
method 1 time: 97.1539468765
method 2 time: 93.4973130226
this clearly shows that the method I suggested is only slightly faster,
so that difference really isn't worth mentioning as you said :)
however, the difference may be slightly bigger when using better ID
generation functions, mine above is very basic so it might have more
repetitions...

One of the problems with the above style is that if the query fails for
some other reason (typo, no permissions, database temporarily
unavailable, etc) the code will run indefinitely (or until it gets
killed for too much time). That's a very dirty way to manage failed
inserts due to dupes.
yes, of course. that's good only for this small test, not for real life
use ;)
for real use one should check mysql_errno end take action based on that

basically yes
but if you want the id of the row you just inserted, using

The reason I have to use it as I posted is because I am using
Microsoft SQL server instead of MySQL. And I haven't found a php

you wrote something earlier as far as I can remember about a MSSQL
function scope_identity() which returns the last inserted id
why not use that?
greets
Zoltán Németh
So, to come out with a comparable function with pretty reliable
results, I follow this process:
1. User enters data into form
2. User submits form
3. Save page inserts info into the database
4. Directly after the insert statement is my SELECT MAX query
5. I assign the retrieved value to a hidden field
6. I pass this value to the next form
I figure the odds of another record being inserted inbetween the time
it takes to go from step 3 to step 4 are very, very minimal. We're
talking about MAYBE a 2-3 millisecond gap?

doesn't show croatian letters... I also tried with encoding utf-8, same
thing...

what is the charset of the webpage displaying the form which triggers
this function? it must be set to the same value as the email otherwise
your email sending function won't receive the croatian letters at all,
so it cannot send them too...

these errors mean that your mysql user 'ODBC' has no password, while you

it is not recommended to have a user without password, so you should

The user data changes frequently and I need to be able to track user information changes, numbers of accounts they are assigned to etc. So rather than updating the user information or keeping one user and tying them to multiple accounts it is easier to maintain a specific user per account for our strict tracking needs. This way I can view all accounts the user is associated with, track user information changes over months/years and provide detailed statsical reports to auditors. I'm sure you could do all that stuff with one copy of the user data and user-account links stored separately... greets Zoltán Németh On 3/20/07, Jim Lucas [EMAIL PROTECTED] wrote: Dan Shirah wrote: I had thought about having the multiple submissions on a single form, but with the amount of user information that is collected and the variable amount of users that may need to be entered this method would not be ideal. (A single form that you have to scroll down a far way and the potential to not have enough user inputs is what prevents this method from being used) Each account is unique. It is possible that the same user could be on multiple accounts, therefore the account will be tied to the user each time. No account_id will be duplicated, but the user table can hold the same user multiple times tied to different accounts. Why duplicate data? Why not do it as suggested? What do you mean by not ideal ??

One table stores all of the account information, the other table stores all of the user information. Table 1 account_id - is the primary key and is unique to each account Table 2 user_id - is the primary key and is unique to each user account_id - will be set to whatever the account id is in Table 1 You are suggesting that when they click Enter another user for this account that I save the account/user information to the database and then when the form refreshes have something like: if (!isset($_POST['submit'])) to determine if this is a continuance of a multiple user submission? And then I should select the account_id that was just created? Using something like: SELECT scope_identity() FROM accounts Or is there a better way to determine the recently created account_id so I can use it for any other user data that is created for this account? Hi Dan, Yes, there is a better way. What you have described is probably more complex than you need, and requires more clicking by the user than is necessary. First of all, do you allow multiple accounts for the same user? If so, you're going to run into troubles with querying later on with the current data schema. Generally, when I'm working with inter-linking data like you describe, I construct it as: Table 1 account_info: account information account_id Table 2 user_info: user information user_id Table 3 account_link: user_id account_id This way, you never duplicate user information, and it is very easy to link or unlink users from accounts. In the web form, if you allow adding up to 3 users maximum, why not just put all of the input on a single page? [html] Account information: Form Field 1: ... User #1 (required) Name: _ ... User #2 (optional) Name: _ ... User #3 (optional) Name: _ ... [/html] In addition, you might consider either using an AJAX-based dropdown, or populating a static dropdown with previous users (assuming the list of users is short), so that if a previous user is entered into the account, that name can be used. In addition, if you have all 3 users on one page, you can validate them all at once, check for accidental duplicates (i.e. if a name matches an existing user, bring up the form and ask if they intend to create a new user, or wish to use the existing one). There are lots of options. If you do decide to do a multi-page form, with database submit right at the last step, there is an example of how I've done this in the code for pear.php.net's election creation interface, at http://cvs.php.net/viewvc.cgi/pearweb/public_html/election/new.php?view=markup . This code makes use of simple php-based templates found in: http://cvs.php.net/viewvc.cgi/pearweb/templates/election-new-step1.tpl.php?view=markup http://cvs.php.net/viewvc.cgi/pearweb/templates/election-new-step2.tpl.php?view=markup

I moved it to a test server and could get it to work but only

Put ?php phpinfo();? into the mypage.php and see if its Master

If they are, then it worked, and you SHOULD see the errors.
Well they weren't different so I guess it didn't work. Seems odd

me that get_ini would show it has having been changed but phpinfo
doesn't.
Sounds like a bug to me -- They ought to at least agree on what the

Check the bug reports and file one, I guess:

I thought I might try a modification of your virtual hosts
suggestion. Perhaps create a virtual host with the same document root
as the main virtual host but turn display_errors on globally for the
debug vhost using phpflag. First I tried it in a .htaccess file and
then in my main apache config file, httpd.conf. Each time resulted in
the error:
Invalid command 'phpflag', perhaps mis-spelled or defined by a module
not included in the server configuration.
you misspelled it, there is no phpflag command actually.
there is php_flag command and php_value command which you can use
in .htaccess files (php_flag for flags which can have On/Off states
only, php_value for others)
hope that helps

I'm starting to think that all of the ini override stuff was
implemented in a later version of PHP than I'm using. Haven't figured
out when it was implemented yet though.

You changed your html code, you have id=1, and in your PHP code you
are requesting img, so change
centerimg src=image.php?id=1 width=200 border=1 alt=/center
to
centerimg src=image.php?img=1 width=200 border=1 alt=/center
But i must also say, it is NOT safe to input data from ?img= directly
into your database, someone could do a SQL injection right away with
this code!.
He's not using image.php to insert. Earlier he mentioned using phpmyadmin to
insert the image, that was the way I used too. First learn to display an
image, this way its easier to know if any upload script you make up later is
working correctly.
evil code can be injected into any sort of sql statement. so it is not
depending on whether he's using the php for insert or not.

}
I hope for you that there's only one item with this id, if not, there
would come an error again, so a while loop is not needed, and second,
now you don't define $encodeddata and $title anymore, try this piece
of code instead of the one above:
$row = @mysql_fetch_array($result);

echo $row['filecontents'];

key, not a value, and array_search searches vor values, in this case it
searches for the value 'date18' and then try's to get the key of that value,
but date18 is a key, so it would probably return false.
Then how would I search for the Key date18 and once I find it how would I
get the value of that key.
$array['date18']
Because even if I change the date18 to it's value
03-13-2007 I still get the error Wrong datatype for second argument. I have
also tried print_r(array_keys($array)); and I get The first argument should
be an array.
first, you should make clear what array you use where
what is the output of var_dump($_REQUEST) ?
and what is the output of var_dump($array) ?
if there is difference between the above two, then there might be some
bug in your code where you create $array from $_REQUEST

Hi,
I would like to know if there is a way how PHP code can extract from
ElementID some property values.
for example, i have the following PHP page :
?php
print div class='maindiv' id='id_maindiv'my main div/div;
$new_Width = somefunction();
print div class='childdiv' id='id_childdiv'
style='width:.$new_Width.px;'my child div/div;
?
in my CSS file (which is link to my HTML page), i have :
.maindiv
{
width : 300px;
height : 400px;
background-color : #EEBBEE;
}
.childdiv
{
background-color : #BB;
}
my PHP code should be able :
- to extract the width of id_maindiv ID (so to get 300px) and to reduce it
by 50px
the problem is that i tried with Javascript and if the property
(style:width) is not define DIRECTLY to HTML code (but only in CSS file),
the javascript is not able to return the value (but only 'undefined').
So i would like to know if PHP could help me in this way ?
I think you can not do it with PHP.
But you can do it with javascript. you have to read the offsetWidth
property of the object, then set it's style.width like
if (document.getElementById('whatever').offsetWidth 300) {
document.getElementById('whatever').style.width = 300;
}
hope that helps

Hi,
I'd like to thank everybody who have helped me till now. All your
advices were very helpfull... :)
But I have a problem again
I need to build a script which will have have the following functions:
1.Be able to select 3 columns from a MySQL database(idnetify the
columns by ID) and put the column contents into 3 textarea objects.
(for example title,Text1,Text2 each into i textarea).
2.Edit and MySQL update the textarea contents
And all in one script.
The script has a $id = $_GET['id'] variable which holds the
information about the certain table id.

This is the script, I have dealt with both problems but when I click on
the update button (submit button) i get an error msg:
Access forbidden!
You don't have permission to access the requested object. It is either
read-protected or not readable by the server.

it should be

because of security reasons

here you don't need $result I think, you could just use

I have several other javascript calls on the page where this call

The original image gets displayed correctly. But in place of the thumbnail
image i get loads of junk text data. I guess the hmtl tags are all in order
as the original image is perfectly displayed.
What have i missed. Any comments, help etc will be appreciated.
either create a filename for the thumbnail and add it to the imagepng()
call as second parameter and reference it in the thumbnail img tag
or put the thumbnail creation in a separate file, say thumbnail.php
then the img tag should be like
echo img src=\thumbnail.php?img= . $photo_img_name . \;
and the thumbnail.php should send out some content-type header e.g.
Content-Type: image/png and then call your function like
echo thumbnail_img($_GET['img']);

Hi,
I'm building an CMS system (for practice and experience :)).

I have a index.php that takes the news from the database and publishes
them. And by the end of every news on index.php I have a link ('a

That leads to a page that has the full news.

And in index.php I have the following code:
while ($row = mysql_fetch_array($result))
{
$id= $row['id'];
etc...

In the database I have two tables one for a short version of news for
index.php and another for fullNews.
In full news the query is: select title,newsFull from fullnews where
id='$id';
In the database i'm 100% sure there is a id = 1 in both rows.
I really dont know what is the problem.
ehh, what is the problem? you didn't tell.
I guess that the fullnews page don't display the news correctly, right?
if so, please show us the code of that page
btw, why are you using two tables?
everything could be put in one with fields like title,shorttext,fulltext
and so on...
and then there would be only one id for one article, which could reduce
confusion and eliminate some possible problems

I shall look into all of it. In the meantime, I am trying a different solution and would appreciate your review of the technique: http://www.sperling.com/a/c/ The point of this experiment is to speak the numbers required for a CAPTCHA protection scheme. I've had a few blind users report that this works for them, but considering all the different platforms and talents on this list, I thought that I would ask Does this work (i.e., speak the numbers) for you? The numbers to be spoken are printed on the top of this page for your notice. If you would be so kind, please review, provide me your platform type and success. Thanks. tedd PS: What does this have to do with php?

Re: [PHP] How to call image from mySql to php file
2007. 02. 21, szerda keltezéssel 06.26-kor Chris Carter ezt írta:
I have a field in database called logos which has one value
images/logos/some_logo.jpg
In my php I am trying to call it in my php file as image. With this code.
$sno = $_REQUEST['sno'];
$query=SELECT logos FROM table WHERE sno = '$sno';
be aware of sql injection. check the data before putting it into a
query.
and also, I do not recommend using $_REQUEST, it is better to use
$_POST/$_GET instead
$result=mysql_query($query);
$num=mysql_numrows($result);
this is
mysql_num_rows($result);
correctly
mysql_close();
$logos=mysql_result($result,$i,logos);
I recommend mysql_fetch_row or mysql_fetch_assoc instead
http://hu.php.net/manual/en/function.mysql-fetch-row.php
http://hu.php.net/manual/en/function.mysql-fetch-assoc.php
if you have several rows in the result then do something like
while ($row = mysql_fetch_row($result)) {
// here you have a filename in $row[0]
// do whatever you want to do with it, for example:
echo pimg src=\ . $row[0] . \/p;
}

I am developing a site at the moment which is causing a very unusual trait in both mozilla and opera browsers. http://www.reedsandmore.com.au/index2.php For example.. * Click on Clarinet Reeds More * Click on Bb Clarinet Reeds * You will see the first page showing the first 12 items (hopefully it will) * Scroll to the bottom and click on Next * Look at the page that gets refreshed... it's the first page again. Yet in the URL it shows the URL for page=2 * Now to actually bring up page 2, you can click on RELOAD, or simply click on Next at the bottom of the screen again. This will bring up the proper page 2. * Now do the same to bring up page 3. Same thing occurs. Page 2 is re-displayed, and page 3 will not come up until you click on Next again, or click on RELOAD. * The same thing happens in reverse back down through the pages. If anyone can point me in the right direction of this or if you have come across this in the past, please any assistance would be greatly appreciated. The code is valid to XHTML 1.0 Transitional as my initial thought was that something wasn't valid. I tried it with Firefox on Ubuntu Linux and IE on XP and the problem appears on both.

Re: [PHP] Manual contradiction concerning string access?

2007. 02. 20, kedd keltezéssel 17.15-kor Christian Heinrich ezt írta:
Dear list,
today, I read in a german PHP forum about a problem with accessing an
offset of a string.
For example, if you have a variable like
$string = this is my string;
and you want to access the third character at once, I would suggest to use
$string{2}
so this will return the i.
The (german!) manual says about that:
(http://de.php.net/manual/de/language.types.string.php#language.types.string.substr)
*Anmerkung: * Für Abwärtskompatibilität können Sie für den selben
Zweck immer noch die Array-Klammern verwenden. Diese Syntax wird
jedoch seit PHP 4 missbilligt.
(Translation:)
*Note: *For downwards compatibility you may use the array brackets as
well. But as of PHP 4, this syntax is deprecated.
The english manual says: (Link:
http://de.php.net/manual/en/language.types.string.php#language.types.string.substr
)
*Note: * They may also be accessed using braces like $str{42} for the
same purpose. However, using square array-brackets is preferred
because the {braces} style is deprecated as of PHP 6.
I'm a little bit confused by now. Which style should I pick? I use PHP 4
and 5. Is there any other difference?
It would be great if someone could solve that contradiction within the
manual, too.
Thanks in advance.
Sincere regards

Reason is, that in order to pop the key-value pair, you do:

$arr_keys = array_keys($arr);
$key = array_pop($arr_keys);

I benchmarked array_keys() function and it is very slow on big arrays
since PHP has to build the array.
benchmark this:
end($arr);
list($key, $value) = each($arr);
array_pop also removes the element from the array so add one more line:
unset($arr[$key]);

since PHP has to build the array.
benchmark this:
end($arr);
list($key, $value) = each($arr);
array_pop also removes the element from the array so add one more line:
unset($arr[$key]);
Yeah, but he's not actually popping the last element of $arr, he's
just using it to get the last key from $arr_keys.
well, sorry, I didn't examine his code just read his original question
saying a function that acts like array_pop()
it's now up to him to decide whether he wants to unset that element or
not :)

Hi there,
I've got two bloody beginner questions: I've created a form with various
text input fields. One is to hold a numeric value (age). Upon submission, I
try to retrieve the value of this field like this:
$age = $_POST['_txtAge'];
later, I use the $age variable to create a message...
$message = Name: . $name . \n;
$message .= Email: .$email . \n;
$message .= Age: . $age . \n;
$message .= Gender: . $gender . \n;
$message .= Info: . $info;
then I send the message:
mail([EMAIL PROTECTED], A Request, $message, _getMailHeaders($name,
email));
Now on to my questions:
$message contains the values of all fields correctly except the age field
(input of all others are alphabetic, only age has numeric content). Why is
this?
what do you mean by incorrect? what is the test input you give and what
result do you get?
Secondly, mail sends my message correctly. But the return adresse set in
_getMailHeaders is not used. Instead, some identification from the server is
used. Why is that?
it is (if you use sendmail on the server) because sendmail sets reply-to
to the user running it by default. so it gets set to the user the script
runs as (usually www-data or something like that). it can be overridden
by the -f switch I think. like this:
mail($to, $subject, $message, $headers, -f.$frommail);
hope that helps
Zoltán Németh
Here the function _getMailHeaders:
function _getMailHeaders($senderName, $senderAddress) {
ini_set(sendmail_from, $senderAddress);
$headers = 'MIME-Version: 1.0' . \r\n;
$headers .= 'Reply-To: ' . $senderName .''. $senderAddress. '' . \r\n;
$headers .= 'Content-type: text/html; charset=iso-8859-1' . \r\n;
$headers .= 'To: PostOffice [EMAIL PROTECTED]' . \r\n;
$headers .= 'From: ' . $senderName . '' . $senderAddress . '' . \r\n;
ini_restore(sendmail_from);

ehh, sorry, I didn't think you use safe mode. If you can not switch it
off, then try to contact your system admin to install a sendmail
alternative which can be configured to read the reply-to header from the
mail headers passed to it by the caller - AFAIK sendmail itself cannot
be configured this way, but I might be wrong
as for the age value:
it is simply incorrect because it is always empty... input might be for
example 25, but the var $age contains always an empty string.
well, you should check the field in your form. does it have exactly the
same name? maybe you misspelled it... (don't forget that it is
case-sensitive, so _txtAge is not equal with _txtage for example)

Can you help? I'm a programmer (C++)
so the concept of debugging code should not be new to you.
so hello to print_r(), var_dump() and echo - they are your friends.
e.g. stick the following at the top of your script (to start with):
var_dump(
$_POST['_txtAge'],
$_POST
);
my guess is your form element name and post array key are not identical.

The logic involved in finding events that match the user-entered dates works
like so:
1. we create a range of dates from the start and end dates specified by the
user
2. we then poll the database for any events that encompass or intersect this
range (using the start_date and end_date fields from events table).
3. we then find out the frequency of the event ie weekly, monthly and then
map out its lifetime.
4. we then go through those dates, and for any that match a date in the user
range, the event on that date (ie all it details, name, venue, date, start
time etc) is added to an array.
...etc etc
So we eventually have a large multidimensional array whose elements contain
arrays of events that fall on a specific date.
I am using usort to ensure the events are sorted by date, but I also want to
sort by time, for instance if there are five events on one day I want to
sort them by start_time.
Here's an example of how the event array looks:
element [0] contains an array as follows ('date', 'name' venue',
'start_time', 'category...');
element [1] contains an array as follows ('date', 'name' venue',
'start_time', 'category...');
I tried using array_multisort but it didn't seem to do what I wanted. I want
to sort by date, then start_time if the dates are equivalent.
Any ideas?

I think i have found where i am going wrong.
Its in the comparison login for the db result.
So i select * from jfjfjfjf where custno=$_POST[number]
But now i am getting messed up with if cust no not found then all i get
is a blank page but hoping for an error
because you get an empty result set if no match is found
so check it like
if ($row = mysql_fetch_array($result)) {
// ok, found
} else {
// not found, error
}
or whatever sql you use
hope that helps

I'm not totally clear what the question was in there. Personally I
keep this simple...
?php
$_POST['number'] =
(isset($_POST['number']) ? trim($_POST['number']) : '');
$_POST['email'] =
(isset($_POST['email']) ? trim($_POST['email']) : '');
if (empty($_POST['number']) or
empty($_POST['email']) or
empty($_POST['password']))
{
die('All fields must be entered');
}
// Find the customer/user/whatever you need from the given details
if (not found)
{
die('Unable to locate customer/user/whatever');
}
// Set up the session here, or however you're tracking the
// current customer/user/whatever
header('Location: /somewhere_else');
?
Hope that helps.

of getting 07, 08, 08, 10 I get 7, 8, 9, 10...how can I get it to output the
two year for 07, 08, 09 without it cutting off the zero?
I think it is because when you calculate $short_years it is an integer.
So insert the following before echoing it out:
if ($short_years 10) {$short_years = 0 . $short_years;}

Nopthing wrong with globals as long as they aren't used to punt data
around from function to function. I find globals quite useful when used
for configuration. I usually use a double level array. The first index
is a grouping index such as someProject the second index is the name
of the property. I could use a database table, but why incur an extra
query. I could use a class, but why increase complexity, I could use
functions, but complexity again.
I greatly agree with this. I use config arrays, and put all
initialization which sets up the elements of the config arrays in an
include file which is included everywhere.
And inside functions these config arrays are my only globals (besides
the superglobals of course).

it will break in the highly unlikely situation that someone uploads a url

an also for things like:

1. a beasty little regex.
2. use the output of parse_url().
parse_url is a great idea, I think I will use that in the future
thanks Jochem

the second is by far the better way of doing this, below a couple of
examples:
?php
var_dump(
parse_url(http.mydomain.com/foo.php?id=1),
parse_url(https://www.foo.org/html.html?arg=a;),
parse_url(ftp://leet.haxordl.org;)
);
?
hopefully the OP has enough brains (I'll assume he does given the 'Dr' title
he carries :-)
to figure out how to use the output to be able to always generate a valid url
from whatever
people are sticking in his form (and/or return a suitable error if someone
tries to insert
some complete rubbish)

you don't have to change the user input part, the user may enter all the

[PHP] preg_match problem
Hi all,
I have a simple checking like
if (preg_match(/[\w\x2F]{6,}/,$a))
as I would like to allow all word characters as mentioned at
http://hu2.php.net/manual/hu/reference.pcre.pattern.syntax.php
plus the '/' character, and at least 6 characters.
But it throws
Warning: preg_match(): Unknown modifier ']'
and returns false for abc/de/ggg which string should be okay.
If I omit the \x2F, everything works fine but / characters are not
allowed. Anyone knows what I'm doing wrong? Maybe / characters can not
be put in patterns like this?
Thanks in advance,
Zoltán Németh

1. You're making your life harder with those double quotes. \x2F is
interpolated by PHP, before the PCRE library has a chance to see the
string.
2. Use a different delimiter and you'll be able to use slash characters
in the pattern freely.
preg_match('~[\w/]{6,}~', $a);
Thank you very much, it's working fine now.

Here is the code:
Here is the entire page:
!-- nav/box 1 starts here --
?php
include(../include/etc_inc.php);
$connection = mysql_connect($host,$user,$password)
or die (couldn't connect to server);
// connect to database
$db = mysql_select_db($database,$connection)
or die (Couldn't select database);
// query a from client

order by companyName;

echo span class='navCompany'{$aaa['companyName']}/spanspan
class='navArrow' /span\n;
// query b from job
$query = SELECT * FROM job
WHERE companyId='{$aaa['companyId']}';
$result2 = mysql_query($query)

foreach($aaa as $jobType)
{
$bbb = mysql_fetch_array($result2,MYSQL_ASSOC);
echo span class='navText'a
href='single_page_t2.php?art=.$bbb
['pix'].'{$bbb['jobType']}/a/span\n;
}
first, do you want to allow several jobs for the same company to be
stored in the DB and appear on the page, right? (if not, then why are
you storing them in separate tables?)
second, you should do it with one query I think
something like SELECT t1.*, t2.* FROM client t1, job t2 WHERE
t1.companyId=t2.companyId ORDER BY t1.companyId
and then you can do all stuff in one loop
while ($aaa = mysql_fetch_array($result))
and you don't need that foreach stuff at all (which also seems to be
screwed up...)
echo br;

and here you should not run the whole query again
you should specifically query the one which should appear
maybe you should use a parameter for it, place it into the link in the
first query loop, get it here and query based on it
like SELECT * FROM job WHERE id={$_GET['job_id']} or whatever
and just echo the data from that record
hope that helps

Hi all,
Try this:

no-one here supports Zend.
it outputs \{}, thus breaking existing scripts.
AFAICT the escaping in that string is wrong - the fact that it did work
the way you want it to is probably sheer luck.
lastly I ran your tests and determined at the least that the 'break'
occur *prior* to 5.2. at a guess it probably changed in 5.0, here are my
results:
# php -r 'echo php,phpversion(),:\n; $a = ; var_dump(\{$s});' ;
php5 -r 'echo php,phpversion(),:\n; $a = ; var_dump(\{$s});'
OUTPUT:
php4.3.10-18:
string(2) {}
php5.1.2:
string(3) \{}
be pragmatic - fix your script :-)
is this the correct form:
$a = '';
echo \{$a\};
if I want to get {} a result?
(I think it is)

all input fields go to $_POST/$_GET depending on the form method you

just do it like
select name=\tyyppi\
and then you will have that value in $_POST['tyyppi'] or $_GET['tyyppi']

so you want to print the same form fields for each iteration on the same
page?
then I would use a method like
echo select name=\record_$count_tyyppi\
which results in
select name=\record_1_tyyppi\ for record 1 and so on
and you can access the values in $_POST/$_GET like
$_POST[record_$count_tyyppi]

2007. 01. 12, péntek keltezéssel 23.30-kor Richard Lynch ezt írta:
I have this process that dumps out database records to static HTML pages.
The basic algorithm goes like:
//Set any un-parented item (a root in the thread) to be its own parent:
update entry set original_id = entry_id where original_id is null
//collect any dirty entries (changed in db, need to re-publish)
$dirty = select entry_id from entry where dirty = 1
while (list($entry_id) = mysql_fetch_row($dirty)){
//find the whole thread:
$followups = select entry_id, X, Y from entry where original_id =
$dirty_id
//there is an ORDER BY which is not relevant
//get some thread metadata from the first row's X field
list($junk, $X) = mysql_fetch_row($followups);
//$X is the same for all rows...
echo h1$X/h1\n;
//reset to row 0
mysql_data_seek($followups, 0);
while (list($entry_id, $X, $Y) = mysql_fetch_row($followups)){
echo p$Y/p\n;
}
}
So, how come *SOMETIMES*, seemingly at random, I get:
Warning: mysql_data_seek(): Offset 0 is invalid for MySQL result index
116 (or the
query data is unbuffered) in
/www/acousticdemo.com/web/complaints/publish.cron on
line 26
Line 26 is, obviously, the mysql_data_seek call above...
I do not *THINK* there is any other process anywhere deleting rows
from the table -- it should be an ever-growing table...
So is the query data being unbuffered out from under me due to some
my.cnf setting?...
Or am I just plain wrong, and *something* is deleting from the entry
table?
I Googled for the error message, and found about a 26,000 web sites
that are exhibiting this error, rather than the folks discussing this
error. :-v
The few I was able to weed out were obvious logic errors, which I
don't think I have.
I've read the mysql_unbuffered_query on php.net and think I understand
it in respect to mysql_query et al.
I guess I'm looking for reassurance that it's definitely my mistake
somewhere in the mess I've made, and that I'm looking for a delete
query, and it's not a subtle bug or feature I'm failing to understand.
