Re: [PHP-DB] mysql not valid resource. .
A thought - if he's getting the 'not a valid resource' from just the code he posted, then his problem is with the $connessione variable, and not the query itself. Check to make sure the connection is up at all/etc. and *it* is a valid resource. Generally (well, in the simple case - which is the general case) you only have the one database connection, and don't need to bother passing it around. Also, make sure you're using resources in the right places later - many times people will use the result ($query) as if it contains the rows returned, instead of being a resource identifier to get the rows. cheers, -- - Martin Norland, Sys Admin / Database / Web Developer, International Outreach x3257 The opinion(s) contained within this email do not necessarily represent those of St. Jude Children's Research Hospital.

Re: [PHP-DB] Finding duplicate contacts..
Well, if you want to be as certain as you can - you're going to need to stick to a fairly rigorous check. What you could do is export the DB into something PHP can quickly load right in (something serialized, for e.g.) every X minutes, and then at the end of the day run your 'rigorous test'. One thing that (might) spare you, is once you've checked a set against itself, you shouldn't need to check it again [depends on how changes are handled]. If you track the records that are changed updated or added, and every few hours (or nightly) check back over that - you'll have a fairly fast performing system that has few likely dupes on the whole. Now, in my opinion you might want to stick with the idea of hitting the DB directly (depends) - but toss in some 'real world sanity checking'. Without seeing the query, I can't say if you haven't already - but chances are you can do quicker passes frequently, and occasionally do the slower more thorough checks. Most peoples last names don't change often - and when they do, they could easily also change phone number and address. Toss in 'soundex' to handle typos if doing it at the DB level, or you can use levenshtein distance [levenshtein()] to catch the occasional typo if hitting the info in PHP. Another thing to note - if you know you're going to have duplicates no matter what your efforts, you might just want to automatically accept new records and let the system mark anything that looks dupe for a human to check over, saving you all that checking on the entry end of things (which I guess are done in batches, PDA sync or some such?) If you realize there will be no fast perfect solution, you can start getting creative with a couple different levels and find a pretty happy balance. cheers, -- - Martin Norland, Sys Admin / Database / Web Developer, International Outreach x3257 The opinion(s) contained within this email do not necessarily represent those of St. Jude Children's Research Hospital. [EMAIL PROTECTED] wrote: We have a table with contacts and we need to determine if someone's already in there but with possibly slightly different info or if the old data contains duplicates. Current criteria (I'm sure there's better): If home phone matches any existing home, work or alt phones. If work phone matches any existing home, work or alt phones. If alt phone matches any existing home, work or alt phones. If a concat of last name, street address and zip match any existing. Table currently contains about 60,000 entries (imported from old system) and we can expect it to grow. Indexes are on home, work and alt phones, as well as last name, street address and zip. Tried it without indexes, it was slow.. tried it with indexes.. still about the same speed. Tried seeing if putting the dupe check into a prepared statement sped it up any. It didn't. Analyzed table. Same speed. Out of 60,000 entries, we have roughly 40,000+ unique phone numbers (that's doing a union on all three phone number columns). So even pre-compiling just that list and querying another table is going to be similar in time issues it seems. For new contacts being brought in, we might have 30-60 at a time (maybe more) so this query would end up being run on each of the 30-60. At 1.5-2 sec for each query, that ends up being a full minute or two to do the whole scan. If I pull the phone #'s and name/address/zip combies into an array in PHP first, it's only like 12 secs, but each user would end up pulling it (and maybe store in a session variable or something) and re-pull it periodically to make sure it's semi-fresh.

I'd suggest using telnet and issuing your get statement right there
telnet yourserver 80

this should give you exactly what your server returns on such a request,
minus any customizations it has for the useragent. View source can lie

There is a function called MM_findObj which does exactly what you

Below is the funtion, and whenever you want to refer to oddly named form
elements, you call MM_findObj('oddlyNamedFormElement[]') (and it returns
an object reference to the form element that you can use normally).
[snip]
An addendum to that, two points:
(mixed js and html examples, patently obvious which is which though)
1) You can use this for more than just form elements, if you give an
item an id. e.g.
div id=my_great_divhello world/div
h8_ie_my_great_div = MM_findObj(my_great_div);
2) This is just a general warning, but I used to stumble into it a lot.
IE creates variables/objects in the document namespace, essentially
polluting it - good for convenience, bad for cross-browser anything. As
an example:
input name=nothing
can be used as just nothing e.g.:
alert(nothing);
... and in fact, you get errors when you try to do things like:
nothing = MM_findObj(nothing);
because IE doesn't like to overwrite its pretty little objects. Which
nobody asked for. The only solution is to use different names for the
javascript variables describing/referring to your form/other elements.
h8_ie_nothing = MM_findObj(nothing);

It looks like you are using register_globals on your development

scripts if you don't rely on this.
http://us2.php.net/register_globals
though register globals itself isn't strictly a security issue, it is a
convenience that can cause unwanted/undue variable namespace pollution.
I'd recommend you disable it on your development machine ( in your
php.ini configuration file ) and then you'll have to set about changing
any variables that are coming from get/post - e.g.
if (isset($submit)) {
becomes
if (isset($_POST['submit'])) {
and the likes.
It's odd that your PHP 5 installation has this enabled - the default
changed to it being off in PHP 4.2.0, and certainly hasn't changed back.

It looks like you are using register_globals on your development
machine. You'll likely find it easier to write safer/cleaner PHP
scripts if you don't rely on this.
http://us2.php.net/register_globals
though register globals itself isn't strictly a security issue, it is a
convenience that can cause unwanted/undue variable namespace pollution.
I'd recommend you disable it on your development machine ( in your
php.ini configuration file ) and then you'll have to set about changing
any variables that are coming from get/post - e.g.
if (isset($submit)) {
becomes
if (isset($_POST['submit'])) {
and the likes.
It's odd that your PHP 5 installation has this enabled - the default
changed to it being off in PHP 4.2.0, and certainly hasn't changed back.

I meant if there should even be a separate page for receiving the POST data. It will depend on how you have things setup, as to whether or not Page1 should POST to Page4 or just POST back onto itself. For e.g. 'detail' pages I tend to have POST to themselves, so you add an item in the page then it enters edit mode. Similarly with list pages, when modifying properties of a listed entity - e.g. activate, delete, share.

Once that's all fixed, go to step 5.

Re: [PHP-DB] Headers sent error msg on one server but not the other ...... .
David Martínez wrote: I suggest you to activate Output Buffering at beggining of your code. It's so easy and should not modify the output of your code. This prevents your error Headers already sent. At the first line of your PHP code, insert ob_start() and in the end of your code insert ob_clean_flush(). If you do not want to use Output Buffering you should remove any character sent, including Cr Lf (\n\r). I think it's so hard and I don't recommend it. Depending of your server, PHP can evaluate \n\r as nothing or evaluate \n\r as an output. Personally I disagree with this. Yes it's easy, but you should never enable a feature to fix a bug or problem when it can be tracked down (although obviously in time critical situations, using it as a 'band aid' is - sometimes - necessary). With a quick pointer he was able to find it, and not impact the performance of his web server (output buffering will take more memory - since it's obviously buffering all the output) More importantly though, with output buffering - no content is sent to the client until you flush - in your suggestion at the end. This isn't always an issue since many scripts do much of their processing at the top anyway, but if nothing is sent to the browser - the users will (the majority of the time) see the page they were on, and continue interacting with it thinking their request didn't go through. This will only increase load on your server and, depending on what the users are doing (and how your backend is written) could throw someone or something into a state of confusion. cheers, -- - Martin Norland, Sys Admin / Database / Web Developer, International Outreach x3257 The opinion(s) contained within this email do not necessarily represent those of St. Jude Children's Research Hospital. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm going to go out on a limb and answer your problem instead of your question - because I don't personally see your proposed method as a good solution for the problem. Put simply, it's impractical to try to approximate how the end users browser will render content, and no matter what you do, you'll constantly be tweaking for exceptions. Instead, we'll attack with the best weapon we have, HTML and CSS. There are a number of ways you can get what you want, but you'll likely have to play with all of them just to get a single working solution. 1) thead/tfoot http://www.w3.org/TR/html4/struct/tables.html#h-11.2.3 This is likely the best bet and simplest way to get what you want - I assume the reason you are wanting to break the content up is because 2) CSS pagebreak options 'page-break-before' and 'page-break-after' can be set to 'always', 'auto', 'left', and 'right' - left and right are for printing on both sides - and afaik 'left' isn't supported by anyone, and 'right' has very limited support - still, as far as pagebreaks, you'll mostly be just forcing them with an always. It's worth noting that this is CSS2 - but it is some of the rare CSS2 that is supported in browsers [though not necessarily all, since there are even CSS1 properties not (properly) supported by all major browsers] 3) PRE tags if all else fails If you can't get any of these solutions to work, you can force your output to behave as expected with PRE tags and approximations. This basically brings you back to your original question - counting linebreaks and characters and the likes, counting the lines by stripping the html output to determine how many characters really would go out (with the ob_* functions, remember though - you're just analyzing, don't leave the html out unless you really want to!). - except it changes to have you cater your output more to be predictable. Also, remember to account for htmlentities if that's an issue, = amp;, etc. Really not a fun solution to entertain, IMO.

Alternatively, if you are using MySQL, you can use DATE_FORMAT to achieve
the same result.
### ORIGINAL CODE ###
while ($row = mysql_fetch_array($result)){
$monthName = array (, Jan, Feb, Mar, Apr, May,
Jun, Jul, Aug, Sep, Oct, Nov, Dec);
echo pb.$monthName[substr($row['start'], 4, 2)].
.substr($row['start'], 6, 2)./bbr\n.$row['details'].\n/p\n\n;
}
Yep, also - no need to redeclare $monthName each iteration. If you
wanted you could also just declare it thusly:
$monthName = array (01 = Jan, 02 = Feb, 03 = Mar, 04 =
Apr, 05 = May, 06 = Jun, 07 = Jul, 08 = Aug, 09
= Sep, 10 = Oct, 11 = Nov, 12 = Dec);
... incidentally, Oct/Nov/Dec should have worked previously afaik, PHP
is fairly forgiving. You can probably also get away with just using
round() to get your integers where you need them, instead of the
declaration above.

Re: [PHP-DB] Sybase CALL statement problems
Anthony Robins wrote: When retrieving ODBC results from Sybase SQL Anywhere 6 and 9 from a CALLed procedure, the output to the browser is being arbitrarily truncated. ?php $DataSourceUserID = user; $DataSourcePassword = pass; $DataSourceName = source; $ODBCConnect = odbc_connect($DataSourceName,$DataSourceUserID,$DataSourcePassword); $CallSQL = CALL mladselmeans( '', 0, , 0, , 0, , 'mladsite', 1 ); $CallTest = odbc_exec( $ODBCConnect, $CallSQL ); odbc_result_all($CallTest); ? The resulting output does contain proper data, but as I said, it simply gets chopped off at a seemingly random point (I have had it chop anywhere from 1500-25000 characters off). The amount of truncation seems to vary depending on the results of the CALL, and when the results are the same, the truncation is the same. Perhaps the strangest thing is that I know for a fact that all of the data is being returned by Sybase... If I use output buffering and send the contents of the buffer to a file before the end of the script, all of the data makes it into the file, but still not to the browser. Trying to free the odbc resource or close the connection results in no output at all. A number of possibilities come to mind - some hackish unfortunately. You say with output buffering the contents make it into the file, but not the web browser. Have you checked your logfiles to see if there is anything - perhaps the script is terminating early, etc. Print something after the table as well, see if that doesn't help. It certainly sounds like something is being buffered. There are reports that this function doesn't return the total number of rows correctly, but nothing more on that as to whether that indicates a problem or not. http://www.php.net/manual/en/function.odbc-result-all.php Also - you may want to view the source, or open that output buffering generated file in a web browser - and see if the same problem persists. It could just be bad data inside the database that's causing for e.g. !-- or span display=none or who knows what - to make it *appear* that the content is truncated. Obviously - you could try something hackish where you output buffer to a file, then emit the file to the browser - but if its all getting into the file I'd say the problem lies elsewhere, and that *shouldn't* work anyway, or if it does it's just a buffering problem in the first place. definitely check all logs. twice.

Re: [PHP-DB] Sybase CALL statement problems
Anthony Robins wrote: I have checked my logfiles, and everything seems to be running smoothly and error free. The truncation occurs wether I use the odbc_result_all function or something like: WHILE( odbc_fetch_row( $CallTest ) ): FOR( $ii = 1; $ii = odbc_num_fields( $CallTest ); ++$ii ): PRINT (odbc_field_name( $CallTest, $ii ) . = . odbc_result( $CallTest, odbc_field_name( $CallTest, $ii ) ) . br); ENDFOR; PRINT (brbr); ENDWHILE; So it is not a problem with odbc_result_all. I have compared the source of the resulting page with the output buffering generated file and it is definitely truncating, no -- or span display=none or anything similar... In one case, the browser page source was 12,196 characters in length compared to 37,127 characters in the output buffer file. As you said, there are some 'hackish' things that I have tried such as tacking on several thousand characters of whitespace to the end of the output, which still truncates, but ends up truncating in the middle of the whitespace... I refuse to resort to something like this. [snip] (silly question) a flush() does nothing? You could also try turning on output buffering, and then just ob_flush()'ing when done (and turn it back off). http://www.php.net/manual/en/function.flush.php mentions some caveats (specifically - some that may apply to you - w32 servers, and mod_gzip). The fact that adding whitespace 'helps' really screams it's a buffering problem IMO. http://www.php.net/odbc_longreadlen mentions truncation, but it's talking about TEXT/BLOB and the likes, since you *can* get the full results, I doubt this is meaningful.

Juffermans, Jos wrote: Hi, [snip] Hello, again. I'm afraid phrasing a question multiple ways over a course of days tends not to have much success. In an effort to avoid populating google with just the question, I will give to you what I would try. ( please note the irony of this now. ) I'm trying to connect to an Oracle database (using ocilogon) which is in a different country and connected to our serverfarm via a VPN (the database has no public access). Unfortunately the VPN or the database is not always available. In those cases I will present the visitor with a page explaining that the service is unavailable. [snip] Is it that it's not always available, or that it needs time to 'come back up'. You may want to try running some random low-traffic application over it to make sure it remains running. Some simple SNMP protocol or even simpler just connect to a remote GKrellM. Heck, a ssh connection with top running would do - just something that is constantly transmitting a trickle of data. My problem is that ocilogon takes a long time to return control if the connection cannot be established - often even more than 30 seconds. I've learned that if a connection can be established it'll happen in only a few seconds (usually within 1 second) and am convinced that if the connection is not established in eg 5 seconds, there is no point in waiting another eg 30 seconds. How can I tell ocilogon to timeout after eg 5 seconds (like you can with fsockopen)? [snip] I can't claim whether or not it will work since I don't have an Oracle server handy, so I will merely name functions and talk a bunch. Essentially, you want ocilogon (complex network function to login to a networked Oracle [in this case] server) to timeout just like fsockopen (fairly simple function to open a socket, including network resources). My suggestion is to try connecting using fsockopen, with the timeout. If it successfully connects - chances are, the majority of the time, your ocilogon that follows will work as well. Unfortunately, the stream_set_* functions rely on a valid stream resource, so they won't work with ocilogon (if there was any chance they would). That would have been a nice route to go otherwise. Another dirty little trick you might use is running the ocilogon in a separate script and making use of set_time_limit() to make sure it doesn't run too long. Just be sure not to set_time_limit() for your whole set of scripts, unless you really want them to abort after the 5 or 10 second limit you're setting ocilogon (unlikely). cheers, -- - Martin Norland, Sys Admin / Database / Web Developer, International Outreach x3257 The opinion(s) contained within this email do not necessarily represent those of St. Jude Children's Research Hospital. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No no no - include() should be the same as if you just placed the code right where the include is, so it would apply it to the whole script. You'll have to call out separately and make it another process, and exec or something - a small script whose sole intention is to determine if the VPN is up. exec() or the likes - like I said - dirty trick/hack.

I will of course research the legality of this before we implement the script. I just wanted to know if this was even feasible before we meet about this. I don't even know where we should start. Sure, you're just issuing POST requests with data from your database, and parsing the output - and entering that extracted data back into your database again. A better question, however, would be how are you planning to handle this once you are ready to run it - are you just storing the address at each corner of your 'covered regions'? You'll need some kind of fuzzy lookup to be able to do all this. Maybe a better solution would be to just link directly to the county auditors website with instructions, allowing the users to do their queries as they're needed?

Try adding

I'm not really sure this is really good practice. Sure, php allows it
but I think you should try to avoid them.
[snip]
It's excellent practice to use dynamic variables* when you need them.
There are simply no practical ways around them in many cases, and they
can make cleaner and shorter code in many many places.
For truly dynamic pieces of code, there's really just no other way
(creating an arbitrary class object for an arbitrary database table and
calling common methods (e.g. validate_data(), add()) on said classes.
Of course, when you're doing things like this, you need to make sure
you're sanity checking your data that much more, as you can get into
namespace issues if you aren't careful.
but if you're careful, you can get fun scary things like this!
$this-{$this-form} = new $this-form;
or this!
$this-result[$table_name][$view_name] =
${{$table_name}{$view_name}}-add($view_data);
... be sure to comment your code :)
* Note: I call them dynamic variables, I have no clue if that's the
'accepted' term for them. Makes sense to me, though.

I really appreciate if you can point me to documentation to how can do this properly or you can help me with some experiance you have doing this. I wasn't going to chime in, but after reading some replies I feel I have to. Bottom line - you need to give more details. The design of the database will not depend greatly on the amount of data inside it, unless there are operations/calculations to be done on/with it. Most people talk number of rows / tables / read|write operations / joins / etc. when talking database design, instead of size - as with proper indexes, the size can affect things very little. For example - if you're designing a database to store 20GB raw movie files - then you might want to rethink storing the gigs of data inside the database, then suddenly you aren't working with a large database at all. So, if you can't give more details - you're going to have to search on your own. Otherwise, you might want to speak up with some more info so you can get better recommendations. My only suggestion with the information you've given - is basically what Bastien said - multiple big iron and big fast hard disks / SAN. Other than that, I can only suggest that you design it well :) P.S. - I wanted to toss in a troll reply about trying SQLLite, since it comes with PHP! - but that's mean P.P.S. - I was also tempted to link to a great tutorial on this - an arbitrary resume writing tutorial, as a mean spiteful joke about being in over your head - but that's just too mean.

You're going to have to merge the results within PHP.
not a valid resource is an error you get when you try to read from a
result set and what you pass it isn't a resource for a result set.
I think you're doing something along the lines of:
$result1 = query_database_one($somequery);
$result2 = query_database_two($someotherquery);
$result = array_merge($result1, $result2);
while (mysql_fetch_row($result)) {
// foo
}
...
Which won't work on any level. mysql_fetch_row takes a resource, it's a
pointer to give the database to retrieve the row. When you do your
query to the database, the database does the query but doesn't return
the full result - instead it just returns a resource to the result, so
you can get it as you need it.
I suggest you start from that information and work forward.

That would work if you just wanted to iterate over both resultsets and
do the same thing, yes. Say, if you had lists of users who signed up for
something in two separate databases, you could print them all out with
that. Since he said union and not join - that is probably his intention.
I can't decide if that code is beautiful or horribly ugly though... I
would have to say it's beautiful so long as the 'just do it' is very
short - if the 'just do it' should be a function - then you should just
suck it up and do two while's. Also, for every result in $result2, you
have to poke at the first database and say any more yet?, which is
hackish.
slick 'obfuscated perl' entry type fix though :) [okay, it's not
obfuscated in the traditional sense]

Re: [PHP-DB] Shopping Cart
the search,
sort them however you want - default to product id, have an option to
sort by price, etc.
It's just a listing of products, like before, they just happen to be
filtered to a specific vehicle/make/model/etc. Join that cart search to
the products table on the pid, pull the information of interest, and
have at it. That cart search is just a table holding metadata on a
product, there's no need to list it until you've already chosen a
specific product.
If you're talking about not knowing how to sort it in SQL:
$my_order_field = 'products.price';
$order_direction = 'ASC'; // DESC
SELECT cart_search.*, products.price, products.desc, products.cat_num
from cart_search, WHERE make='{$_POST[make]}' AND
model='{$_POST[model]}' AND year='{$_POST[year]}' AND products.pid =
cart_search.pid ORDER BY $my_order_field $order_direction;
but maybe I'm misunderstanding the problem, you seem to have everything
under control...
P.S. - If you have it (the data) in digital form, I highly recommend
setting up an import. Your interface won't get the testing it would
otherwise, but it will sure save a huge heap of hours, for someone at
least. If you get updates in digital form, you can always diff them and
just add the new bits. The error rate approaches zero much faster
without the human factor.

These are the two columns we need for this. [snip] Now I want the scores added up. So using the + not * (times) but just adding. So for Bob is 5 + 3 = 8 and this figure must than be placed in another table with that name. What I want to do is just have one code written up so I don't need to change it. So in other words the code would include all 22 tables and the method to add each other together and update to the actual main scoring table. So the score aRE updated once a week. I don't mind if I need to trigger the update (preffered) from a php page/script. That's not the problem but I want to know what code I would use to grab these details and add them up using all 22 tables in the one script. So each time the script is ran it will re-calculate all tables to make sure they are correct if an update is made to a score. So the script would grab all 22 tables score and nickname and than match the nickname and update their score in the scoring table. What I have is this: My Tables are round 1 through to round22 and the scoring totals go into table called tipping. So round1 through to 22 need to be calculated and keeping the totals for each nickname correct with their totals. Don't want the scores to be jumbled with a different nickname. How would I do this that would be a pretty fast process and reliable? If you need more information please let me know. Each round table will have identical Nicknames in each, none will have more or few, same amount. Keeping in mind each round that has not had a total set is defaulted as nothing in the score field, it's blank. But if it's required to have a value of 0 in there for the calculations to work I can default this in. If anyone can help me here it would be great, I have been stuck on this for a while. There is only going to be like 15 names max in each round to do totals for so it's not a huge database. Thanks for your time. [snip] well - two options spring to mind... 1) use a single table, with 23 columns instead of 2. Then sum the columns in your query. - 1 query, no loops required. 2) have your script pull everything and add it all up. - 22 queries, a loop for each, array storing scores indexed by name. anything else is going to be a join from hell. With only 22 tables and 15 rows in each table, you literally won't be able to blink before either of these methods would be finished calculating your totals. Whatever you code up will be as reliable as the code used for it :) A better question to ask is, will this be something that cycles yearly or regularly? If so, you'll want to be storing some identifier for the event/session/quarter/year/etc. - in which case any join option would be insanely further compliated, and all of your queries would need the chunk added.

Actually I disagree strongly unless your intention is to be able to read the rows yourself ! As the stated intention is to add up scores (doing the maths) in fact much more efficiently you want to have just 3 columns in a single table, tblBlah : UserRoundNumber RoundScore Bob 1 6 Bob 2 2 Bob 3 3 Steve 1 5 Steve 3 1 Steve 4 6 [snip] Now you've got a list of rounds and the average score per round. And you don't have to write a gigantic query across 23 tables like SELECT tbl1.RoundScore, tbl2.RoundScore, tbl3.RoundScore, tbl4.RoundScore even if that was practical (you'd have to use outer joins and the result set would be huge). Using multiple tables, or even multiple columns is deeply inefficient for this. You can set up a couple of queries to merge all the tables into one in a few minutes, it's called database refactoring and in your case would improve the manageability of your data by10x. [snip] Using multiple tables was described for comparison reasons, to show why it was not a good idea. Using multiple columns is the most space/time efficient - assuming players aren't only playing a few rounds. It is, however, not the most *flexible*, as you're saying. You need to modify the number of columns if things ever change, though you aren't limited to the number of players. Your database is fully normalized, but has the penalty of storing more data (minor), and is slightly more work on him if he wishes to display a summary, which I assumed was also part of his intention. Your way is the way I would do it for a full proper application, my suggestions were the way I would do it if it is something where the rules simply don't change (think sports/etc.) - I gave quick and simple suggestions for (what I saw as) a quick and simple app. I agree with your solution wholly, if his deadline isn't in 2 hours. Unfortunately, all too often our deadlines are yesterday. For this sort of table, you would create an index on each of the 3 columns to imccrease the query speed massively. A nice side effect apart from speed, is that data stored in this way takes up no space if a (new) user hasn't completed any rounds (for example ;-) [snip] One should be indexing all their tables properly :P All good valid points, well said.

The relevant bits:
GROUP_CONCAT([DISTINCT] expr [,expr ...]
[ORDER BY {unsigned_integer | col_name | expr}
[ASC | DESC] [,col_name ...]]
[SEPARATOR str_val])
mysql SELECT student_name,
- GROUP_CONCAT(test_score)

Or:
mysql SELECT student_name,
- GROUP_CONCAT(DISTINCT test_score
- ORDER BY test_score DESC SEPARATOR ' ')
- FROM student
- GROUP BY student_name;
The default separator is the comma. Just toss in a 'GROUP_CONCAT(year)

You're calling a classes method statically when it cannot be called as

You need to create an instance of the object, then call the method

E.G. instead of:
DB::connect('some','variables');
you have to use:
$mydb = new DB;
$mydb-connect('some','variables');

Re: [PHP-DB] Updating many records at a time
Steve McGill wrote:
I have a situation where I am doing lots of complex sorting on records that
already exist in a MySQL table. The table has a 'sort_order' field which
means I can do a simple ORDER BY sort_order to keep it nice and quick on
SELECT, it's only UPDATE which is slow.
If I change the order that I want 1 rows to be displayed, I am currently
making 1 SQL queries such as:
UPDATE products SET sort_order=0 WHERE id='5';
UPDATE products SET sort_order=1 WHERE id='2';
UPDATE products SET sort_order=2 WHERE id='32';
and so on.
Obviously I'd love to be able to put all of this into one query.
Is there some way I can combine this with IN() ?
UPDATE products set sort_order= WHERE id IN('5','2','32');
Many thanks in advance for any help / advice.
What is the exact operation you're doing? Is there any possibility you
can do UPDATE products SET sort_order=sort_order+1 WHERE sort_order
30 for e.g. - as in you insert an 'item' at spot 30 and want all the
rest below it to be bumped up one.
You can certainly use IN(), but there is a (quite high) limit on how
long the query string can be. It's pretty ridiculously high actually,
but something to consider.
Personally, I'd look at how you're doing things - see if there isn't an
alternative way to do it like outlined above. I'm assuming these aren't
just some precalculated ordering, they're manually ordered for some
reason? If it's not 'we want to manually order them' - In a products
database, I would think you could just have an ORDER BY product_group,
product_name or some such.

Comment out the 'require' line - and run your test script. I expect
you'll get the result Ok. If so, you have something somewhere that's
already including DB.php.
Are you running this test script from within something, or do you
actually include some 'common libraries' (your own custom, or some
frameworks?). You may also try changing it to require_once, in case
something is already require'ing it.
The error is clearly stating that there's already a class DB defined.
It's defined somewhere.

$_POST is likely empty, because the user requesting the page has likely
not submitted the form (yet). What you probably want (since you aren't
going to lower the error reporting levels) is:
if ( isset($_POST['op']) $_POST['op'] == 'ds' ) {
// do your operation here
} else {
// print your form/etc. here
}
You may want to use a different quoting style - I can't recall the name,
but it's taken from perl
echo EOF
form action=$_SERVER[PHP_SELF] method=POST
...
the rest of your stuff, then on its own line right at the beginning of
the line (no tabs/etc. :( )
...
EOF;
it basically echo's until it sees that delimiter, that could be EOD or
STOP or whatever (well, there might be reserved words issues - I could
more easily check if I could remember the name of the quoting style...)

No no no - you're confusing the guy further. He's taking an array post

I did try that, but the input is going into one column or it is take
the last array value and put it each chart in the table.
input type=checkbox name=games[] value=football /
in that case, these are the value i got in mysql: f, o, o, t
foreach($_POST['games'] AS $game = $value)
$valuecount = count($_POST['games']);
for($i =0; $i $valuecount; $i++)
$sql = mysql_query(insert into interest
values('$value[0]','$value[1]','$value[2]','$value[3]'));
[snip]
what he wants is (I think):
foreach($_POST['games'] AS $game_name) {
$sql = mysql_query(insert into interest values('$game_name'););
}
or something similar. The idea is that they check 3 boxes for football,
soccer, and hockey - and it inserts three rows into the database. It
seems like we want to be inserting more than just the game though -
surely the user it's associated with / etc.
Moses - be sure to use curly brackets {} around blocks. Your above code
only runs the $valuecount = bit inside the foreach, which is why
you were spared it running 'squared' times (e.g. 2 games = 4 times, 3 =
9, 4 = 16). The foreach and the for($i= code above are both there to
accomplish the same thing, but $value stores the last seen value, so it
would have looked as if you were still inside the foreach's scope.
Stick with the foreach imo, since you don't need the counter. (you can
get it back by using your foreach, the counter is the $game = part -
in my example I left it out since it's unnecessary.

Here is a brief background of the problem:

4) I am using a JavaScript application for my navigation menu. I
chose this because I need collapsing menus. There are lots of functions
under each category; if I were to use HTML for the menu, my users would have
to scroll way down to get to where they want to go - especially the ones
still using 800X600 monitor resolution. A php function calls the JavaScript
menu and changes what is displayed based on the session array data.
Here is the problem:
My JavaScript menu DOES NOT always display. It displays about 95% of the
time. When it displays, it displays correctly (based on the session data).
When it doesn't display, I hit reload and it usually reappears. What's
worse, it seems to happen randomly! I could click the same link 10 times
and it will work perfectly. The 11th time it might not show up.
Here is the small amount of information I know about the problem:
I have read through the list server achieves and think the problem may lie
with the fact that Javascript has to run at the Web Browser end and PHP has
to run at Server Side. This probably explains how it is possible that the
two are not in sync but it does not explain WHY this happens about 5% of the
time. It also does not explain why it happens only to the JavaScript while
always displaying the results of my php functions.
[snip]
Your problem is that your javascript menu functions don't use an onload
handler. What you need to realize is that the DOM may not have finished
loading all the objects in the page, even though the object may have
been printed out to the browser.
so the (pseudo code) equivalent of:
---
input type=submit id=op name=op value=Operation /
script language=JavaScript
operation_button = my_find_item_func('op');
/script
---
may be holding null for 'operation_button' because op hasn't been added
to the DOM yet. You have to wait until the page fully loads, then call
a function to find that 'op' button.
The reason it works most of the time, is probably because it's not being
triggered until you mouseover the menu. Try loading the page with your
mouse nowhere near where the menus should go, and the problem may
'disappear' (note: obviously not a solution). There's no guarantee, but
that's a distinct possibility.
Search for body.onload or window.onload functions.
Also, whatever dropdown code you're using - if they don't describe doing
this, you probably can find better. Any sane packaged dropdown code
should be explicit about requiring the user to use onload to instantiate
things.

Re: [PHP-DB] mysqli connection problem
My intention of setting the reply-to was not to offend, or claim you were wrong - merely to move the discussion to the list I felt (and still feel - as I've done it again) is most appropriate for the question. anyway, back to the task at hand ( first: I'm assuming you restarted apache after changing your php.ini - otherwise, that's your problem. ) Whatever the case, the error message clearly shows that it is not reading the value, however it's set - because the error is still showing a blank string for the socket. If it were a permissions problem with the socket, you wouldn't be getting that exact error - at the very least, it would still show the correct socket path. More likely, it would also error with a cannot open socket or equivalent. You may wish to examine ini_get(), ini_get_all(), phpinfo(), or php_ini_scanned_files(), to verify if it is set, or to see if it's being overwritten somewhere.

You just posted a mail saying problem solved, RTFM - but I just spent a
few minutes tracking it down before realizing it was staring me in the
face - and I didn't want others to miss out on the fun.
Basically, it boils down to the fact that you were accessing the same
objects properties throughout all your accesses within the class.
Namely, $this-who_fricking_knows. (technically $this-null I suppose...
interesting question, don't feel like creating a dummy class just to
find out though).
$this-$mysql_link should have been $this-mysql_link
$this-$mysql_result should have been $this-mysql_result
etc.
dynamic variables are very handy however. You'll find yourself using
them a lot if you have lots of similar tables/etc. that you need to
write the same 'thing' for over and over again.

Sometimes helpful but not always if you have alot of
includes in it. ;)
So I'd say it's this part the error is:
if ($c=OCILogon(scott, tiger, orcl)) {
I didn't take this one up initially because it's all carbs - no
nutritional value.
The entirety of his example is commented except for the single line
(line 3) calling OCILogon. Since the error isn't that the function is
undefined, and it (to my eyes) describes nothing - I stayed quiet.
The line you're suggesting he check (line 6) is in fact commented out.
It does bring to light, however, the suggestion that he check whether he
should be passing more arguments to the function.
You make a good point - that is that the example code is there to make
sure things are working, and then to start changing it - get a good
baseline, and work from there. Sound advice - would that more heeded it.

If you're quoting these values, you should be having no problem.

Looking at the page, and the code block - the code likely isn't running
three times. You have 3 rows in the database, and in your while() loop,
you print out the data for each row 3 times. You'll notice on the
sidebar in the webpage you have essentially 9 'blocks' of news - they
images for them loop (a b c, a b c, a b c) and the text for them repeats
( d d d , e e e , f f f ).
Change your loop to print just once, and have a counter that sets the
image to load (and if the counter goes beyond 3 - either have it not
display the image, or add more images :), or limit the query to only
return the latest three (add limit 0, 3 to the query) )
