[PHP] Error handling strategies (db related)
How do you guys handle errors during, say, db insertions. Let's say you have an ongoing transaction which fails on the n-th insert. Ok, you roll back the transaction, no problem. How do you then inform the user? Just using the text from pg_result_error or something? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If it's a normal user, give them some info about what went wrong but not the specific error returned. If it's an admin with dev knowledge (i.e. you) then consider handing out the returned error as well. Rule of thumb: aim to inform the user without confusing. There's nothing worse than This didn't work, sorry - why didn't it work?? Was it my fault? Can I get it to work somehow?

Developers are usually lazy about error reporting because it's much easier to just return the error code. Some parsing is very useful to the user, since overtly technical information is just confusing. The error should never be something that the user himself can avoid (since you're supposed to have error checking and handling before the user submits), so your error should make this clear to him. It helps to let him know that the developer has been notified and that he can try again later. Michiel

[PHP] Weird while issue
Hi guys,
I have some issues with while.
I have an HTML Form, that uses GET to process its contents. Then
there's a PHP Script that receives the data, and evaluates the fields.
So, in some instance of the code, I do something like :
if (empty($a) AND empty($b)) {
echo something;
echo something;
echo something;
while ($row = sqlite_fetch_array($results,SQLITE_BOTH)) {
And here I print some echo's to print an HTML's Table with the results
of the while.
echo Something more;
echo etc;
}
} elseif (empty($c) AND empty($d)) {
Here there is another elseif similar to the first one explained above.
}
I have four or five elseif's that analizes the fields of the HTML's
Form and then the PHP's Code do things depending of the combinations
of fields submited and so on.
The problem is that if I want to add an echo saying Come Back to
Index to index.html, I'm not able to show it after the while's
iteration.
The PHP code prints the table with its results taken from SQlite
perfectly. Also it evaluates all the conditions flawessly. However, If
I add a link to come back with the text Go to Index after the while
and before the } close to the next elseif, PHP prints it in the wrong
ubication.
I got something like:
TITLE
*** Go to Index ***
While results. This is the table containing all the results of the
SQlite's Query.
If I move the echo to other part of the block, I receive so many
echo's as iterations the while do ( this is logical ). However I don't
understand why the echo is printed above the while even when I put it
after the while and out of the while's block.
Thanks a lot!.
Juan

I know :( Originally I couldn't find a nice way of translating between db errors and user errors. The only interface to the db errors that I could find was the error messages returned from pg_last_error. Yes, I could have used an array translating between the the strings returned by pg_last_error or whatever, but *gag* it would not only have made the code look horrible but would also have been susceptible to changes in the error messages returned by the db interface. In the end I changed tack slightly and used pg_send_* and pg_result_error_field to get a short code I could use as a reference into an array. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] finding out datasets in a certain distance of a zip code
Hi there,
I am trying to find mysql db entries inside a tabel with the help of php
that are in the distance of a certain amount of kilometers from a given
zip code.
Unfortunatelly something must be wrong, as I do not get the desired
results. Has anybody experience with that?
Here is the code I wrote:
$plz = '79279';
$distance = 1000;
###
# find geo data for this zip code
$stmt =
SELECT
lat,
lang
FROM
test.zip
WHERE
zip = '$plz'
;
$row=db_get_row2($stmt);
$breite = deg2rad($row-lat);
$laenge = deg2rad($row-lang);
###
if ($breite){ // only if results
###
# search for the members
$stmt =
SELECT SQL_CALC_FOUND_ROWS
cl.ID,
g.city,
g.area_1 AS quarter,
g.* ,
IFNULL( (
ACOS( (
SIN( $breite ) * SIN( RADIANS( lat ) ) ) + ( COS( $breite ) * COS(
RADIANS( lat ) ) * COS( RADIANS( lang ) - $laenge ) ) ) *6371
), 0
) AS e
FROM
test.zip g,
test.cl cl
WHERE
IFNULL( (
ACOS( (
SIN( $breite ) * SIN( RADIANS( lat ) ) ) + ( COS( $breite ) * COS(
RADIANS( lat ) ) * COS( RADIANS( lang ) - $laenge ) ) ) *6371
), 0
) $distance
AND g.id = cl.zip_id
GROUP BY cl.ID
ORDER BY
e ASC
;
$result = execute_stmt($stmt, $link);
while ($row = mysql_fetch_object($result)){
$entfernung_km = round(($row-e*1.4),2);
echo 'cl: '.$row-cl_id.' '.$entfernung_km.'br';
}
$num_results = db_numrows($result);

The point here is that we, programmers, know that we write code with bugs in it. We are realistic about it, that is, we know that perfect code does not exist, and that there are bugs in it. So what we care about is to bring this reality to the users in a gracious manner. And the other thing is that if for example a database is down, that is not our fault, it is an external error, but this error should be brought to the user as well.

I do something similar with the accounts I want to monitor.
For example, when I access the database during development, I use
code similar to this --
// --- script
$sql = SELECT * FROM users WHERE user_id = $uid ;
$result = mysql_query($sql) or die(report($query,__LINE__ ,__FILE__));
// --
-- and then a report function similar to this --
// -- functions
function report($query, $line, $file)
{
echo($query . 'br /' .$line . 'br /' . $file . 'br /' .
mysql_error());
}
// --
This provides me with information as to what happened and where.
When the project goes live (out of development) then I replace the
report function with code that can send me an email telling me what
happened (to what domain) as well as an explanation to the user
(screen display and sometimes even email) and sometimes an email is
sent to the client (i.e., the user's credit card was denied for xxx
reason trying to purchase product xxx at this date).
Note, all my error reporting functions are located in a single
function script that is included with every script that has access to
the database. That way I can turn on/off error reporting and make
alterations as to how to handle errors in one file. The difference
between development and live is a simply a change in one script.
Error handling is almost an art form.
Cheers,
tedd

A good example of friendly error documents can be seen at most of the major sites around the web that we all frequent (or are at least aware of). Further, these friendly documents make it clear that the error is a server / application error and that no action the user takes will fix the error.

Ted already mentioned the DB route using PHP, but you could also use PHP to set up an XML schema that represents quizes (e.g., quizquestion id=1textWill this work?/textoptionsoptionYes this will./optionoptionNo it won't./option/options/questionemail respon...@msu.edu/email/quiz) With this type of scheme (one in which the html form is automatically built up from an XML document), you could just have the results emailed to an account as individual TSV file attachments (that's why I included the email tag in the example above), making it easy for anyone to tally the results after dragging the documents into Excel. Last, you can also leverage existing technologies. In addition to quiz generators available online, Google Docs allows you to create forms that store responses in spreadsheets (Create New - Form). You can choose from a variety of response types (text, multiple choice, etc.), and it works quite well.

[PHP] auto indentation
Hi everyone.
I got a quickie LOL
is there a way to auto indent code. I'm using Kate and I have it set so the
tab is only 4 spaces, but I was wondering if there was an easier way than to
have to hit the tab key 1x then 2x then 3x then 2x then 1x to create nice laid
out code like this:
-
-
-
-
-
-
-
-
-
or:
function() {
function here
}

I use Kate too, and the indentation changed slightly in KDE 4. In the
configure dialogue window, go down to the Editing section in the left
menu and set the number of spaces to use in both the General tab (under
Tabulators) and the Indentation tab (under Indentation Properties. If
they are both different then you have to hit the tab key 4 times in
order for your spaces to be replaced by a tab character.

Thanks Ash. What is your preferences for indenting code? Do you have it set
so you don't have to hit the tab key at all? I set my numbers in kate to 4
what about you?
