Ajax interactions usually produces different results, 'cause an Ajax
interaction that returns an entire document does not make much sense.
Formaldehyde is for Ajax interaction, which "in my case" I always catch via
headers checks or special parameters.
Formaldehyde is client agnostic, FireBUG or FirePHP could or could not be
there, but providing both server and client code, we do not have to worry about
anything.
Finally, even if called manually, the page will have a status 500 and the error
will be still readable, being it the first JSON encoded key but obviously, for
manual interactions it is extremely simple to spot the error, if any, since PHP
clearly shows it in the page, if there are no other debuggers.
The stuff about application/json does not make much sense to me, and FireBUG
shows automatically things passed via eval, it is not about the response type
(also because it could simply be a security problem)
Again, Formaldehyde, is client side agnostic, so if we have IE, rather than
Firefox, or Safari, Chrome, Opera, Formaldehyde will work, helping with
unmanaged PHP errors (or managed one, if we manually throw an exception or
trigger an error)

The only
things that may go wrong are in the data I am sending to the ajax
routine AND/OR the way my php scripts deal with the data when they
receive it.
Formaldehyde tells you in the client debugger what was wrong in the
php code indeed.
Did you actually read the page before you replied?
No, I didn't read the page before I replied. YOU asked a question and
I replied (read the thread) -- I'm sorry that I did. I'll refrain
from doing it again.

Andrea has gotten without sounding rude and likely starting an internet
fight, so I won't say anything. Except for this. Tedd, the ajax example you
linked to does not need any debugging, that is for sure.

i did that long ago when i was looking for php's object literal syntax. i
didn't find one. we discussed it here more recently and consensus appeared
to be that casting an array was the most convenient workaround.

i shamefully beg your pardon, lars. i was sure i tested the example but it's
clear to me now i either didn't or i made a mistake. end($o)->a IS php
syntax! so -> may follow a function (or method, i guess) call.
but let me give you a more different example:
$a and $b are normally both objects, each with various members including a
prop q, but sometimes $a is false. i want the q of $a if $a isn't false,
otherwise that of $b.
($a ? $a : $b)->q // is not php, afaik
before you suggest one, i know there are simple workarounds.
but mine is a theoretical question about syntax, not a practical one. i'm
exploring php's syntactic constraints on the -> operator in contrast to,
say, the + or . operators. and in contrast to other languages.
for example, the . in js seems more generally allowed than -> (or, for that
matter, []) in php. programmers (especially using jquery) are familiar with
using . after an expression that evaluates to an object, e.g.
<body>
<p id="thepara" class="top x23 indent">My x class number is
<span id="num"></span></p>
<div id="mandatory" style="border: solid red 1px"></div>
<script type="text/javascript">
document.getElementById('num').innerText =
( ( document.getElementById('optional')
|| document.getElementById('mandatory')
).appendChild(document.getElementById('thepara'))
.className.match(/x(\d+)/) || [0,'absent']
)[1]
</script>
</body>
which shows . after objects, method calls and expressions (as well as the []
operator applied to an expression).
do we just live without in phpville or am i missing something?
and while i'm at it, and using my original error, how come...
function o() { return (object) array('q'=>7); }
echo o()->q; // is ok syntax, but
function a() { return array('q'=>5); }
echo a()['q']; // isn't?
--- End Message ---

because this is simply not valid syntax for the INTERPRETER PHP
while this
> echo o()->q;
can be interpreted because of the design of the interpreter.
I can live with that.

The reason why I used incremental value from the db is that I need a sequence
number generator that can be used as an argument to my function. If I can
generate sequence number myself, I don't need this incremental value from
db.
What I want is that the sequential alphanumeric id that increments it's
numeric value by one everytime a new record is inserted while the alphabet
part remains the same..(like I've shown before):
AAA0001
AAA0002
...
AAA0009
AAA0010
This id will be used as the application number that will be printed as a
barcode on the user's application form. The requirement says that the app
number is prefixed with the letters (actually it's not 'AAA' but 'FIN' which
stands for File Identification Number)....
Things to consider.
First, if all your application-numbers start with FIN, then my advice
would be to do this after you pull the ID from the database. Why
store an additional three characters for each ID? And why make your
code more complicated than it should be?
Second, considering that you want sequential numbering, are you
prepared for what what happens when you delete an item? You either
live with gaps in your sequence (recommended) or you renumber.
Third, your example limits the number of applications to 9999 (i.e.,
AAA9999 (seven characters)), is that correct OR is the next number
AAA1000 (eight characters)? If the next number is eight characters,
then why not use "AAA1" as the start of the sequence? Why the extra
zeros?
Fourth, if you are going to use the index of the table for creating
the application-number and require the addition of the alpha prefix,
then I would create another field in the table and store the
application-numbers there.
For example, I would use (not tested):
// code to create a record (i.e., INSERT INTO your_table (whatever)
VALUES ('$whatever') )
$id = LAST_INSERT_ID();
The above statement finds the last record added to the database (the
index of the record) and then I would create my application-number
and store it in that record -- like so:
// code to create the application-number (i.e., $application-number =
'AAA' . $id; )
$query = "UPDATE your_table SET application_number =
'$application_number' WHERE id = '$id' ";
$result = mysql_query($query) or die('Error, query failed');
That way you should not have any duplications and you have
application-numbers (as you want )that are tied to the auto-numbering
of the table's index.

Paul:
I wouldn't use Hurricane Electric if their accounts were provided for free!
The following is an experience I had with Hurricane Electric and
support for my opinion as to their "service".
You see, many years ago Hurricane Electric hosted (IMO with
complicity) a porn site that sent out over 2000 porn spams to AOL
using MY email address as the person to contact. That incident caused
me a great deal of trouble.
In an attempt to understand and resolve the problem, I sent several
emails to Hurricane Electric; I called them numerous times via
telephone; and I even sent them letters via the US mail. But
unfortunately they refused to answer ANY of my correspondence. Their
lack of communication provided support for my opinion of their
complicity with what had happened.
A few years back they contacted me (again more spam) soliciting my
interest in hosting with them. Normally, I would have just reported
such spam to spamcop, but because of the incident I replied and told
them what had happened.
Later I was contacted by one of their technicians who looked thorough
their records and confirmed/admitted the incident. However, he told
me that they could not be held responsible for they clients they
host. Furthermore, they have no intention of screening their clients.
He said that they will provide hosting to whomever they want,
including porn and spam sites. If their clients do anything wrong per
"their standards", then they will deal with it internally. Otherwise
they don't care about any harm done to anyone by them hosting such
sites. In short, they want the money but not the responsibility.
Now, maybe Hurricane Electric has changed its ways, but they can't
change their past.
In my opinion, there are more than enough hosting companies who care
about the damage they might cause and take steps to reduce the about
spam and porn on the net. My advice, seek hosts other than Hurricane
Electric.
Cheers,
tedd
