Well, that works! :-/ (I'm embarrassed to say)
For some reason I over-thought that one.

[PHP-DB] clues to cache-like behavior
Hello, I took some PHP/MySQL code that seemed to be working fine from a LAMP setup and brought it to a MAMP (mac OS) setup. Now I am seeing a cache-like behavior in my admin forms, where my last changes don't "stick". To be clearer, I go to make a database change in the forms I built to administer the MySQL db, hit submit, then check the results on the public side. All is fine at this point. The changes are there. However, I decide to adjust something and go to make another edit, however, my admin form shows the prior data.. not the last edits. Checking via command-line the edits are there, and if in and out of the edit page a few times, the last edits finally appear. Anyway, I've only built a couple MySQL driven sites so far, and haven't gotten all the way through my O'reilly MySQL book yet, but I thought I'd see if this kind of thing rang a bell with anyone. If I had to make a blind guess, I'd guess a config issue (either PHP or MySQL), as I don't remember this behavior in the LAMP setup. TIA for your comments.

You're using double-quotes to encapsulate your $insert variable
data, then never closing them. What's more, you're also using
double-quotes to encapsulate each individual variable in the query.
Rewrite $insert to this:
$insert = "INSERT INTO user_info(login,password)
VALUES('".mysql_real_escape_string($login)."',"'.mysql_real_escape_string($password)."')";
Look at that one more time Dan. ;-)

[PHP-DB] stripslashes ( encodings to from MySQL )
Hello, I use mysql_real_escape_string() to escape data for db population. ie. ..form.. ..recieving form input before db update.. $var =mysql_real_escape_string($var); My question is regarding when wanting to allow HTML within a database... Will stripslashes also take out the slashes from something like this?: some text That would effectively negated the ability to use HTML/CSS in your db. If so, how do you get around this with safe data entry? TIA, Donovan -- D Brooke -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] 2nd Pair of eyes please
Hello,
to respond to some of the comments/questions..
No, it wasn't parsing anything... and yes, I put
ini_set('display_errors', 1);
error_reporting(E_ALL | E_STRICT);
at the top of the page.
(as well as there is a custom built PHP management app that
allows to turn on the display_errors.. which is apparently
done.)
Having said all that, this server config (of which I have very limited
access) does appear to shut down parsing
entirely more quickly than my dev machines that are set
as mentioned.
..usually not a problem (old hat in troubleshooting) and am nearing the
end of the this job... but yes, strange that small errors trigger
shutting down parsing entirely.
Daevid,
Lot's of misc. comments for not being able to spot my syntax issue and
not knowing the details of my project! ;-)
However, I will take a look some time at your wrapper for future reference.
Cheers,
Donovan (1 block of code at a time)

[PHP-DB] 2nd Pair of eyes please
O.K., I give up.. I can't seem to find why this breaks the page to
a point where nothing gets displayed in the browser (no error reporting).
Sorry for any email line breaks:
---start-
if ($t_dataon) {
$query = "SELECT
s_sitename,s_logopath,s_headinfo,s_head_moreinfo,s_rightpic_path FROM
site WHERE (s_id=31) LIMIT 1";
if ($a_r = @mysql_query($query)) {
while (list($tname, $tlogo, $thead, $tmorehead, $trpic) =
mysql_fetch_row($a_r)) {
$t_sitename = "$tname";
$t_logopath = "$tlogo";
$t_headinfo = "$thead";
$t_moreheadinfo = "$tmorehead";
$t_rpic = "$trpic";
}
} else {
// Problem with query
print = "";
}
}
end-
If I take it out, the page renders. Any ideas?
TIA,
Donovan

Oh, sorry, I must've skimmed that part of the message. If you're
not changing the value from the default, just omit it from the query.
You can't send an empty value. If, for whatever reason, you MUST send
the `vbool` column data in your UPDATE query, then define it: 0 =
false, 1 = true (of course). Two easy workarounds here:
Thanks Dan, I'm sure that would work, but it appears I figured out where
I went wrong...
Read below at your own risk of becoming confused. ;-)
As of now, "false" causes MySQL to input the correct value, which is "0".
I was originally trying to initialize/set the var inside the checker:
if (filter_input(INPUT_POST,'f_bool',FILTER_VALIDATE_BOOLEAN)) {
$vbool = $_POST['f_bool'];
} else {
}
The very strange thing is that, though the "else" statement was never
thrown, anything inside the if (true) statement was not enacting... thus
MySQL was getting an empty value, because the variable was never
getting set.
Strange, anyway, I bypassed the filter and now MySQL accepts false
boolean's.
I'll now have to figure out how to correctly validate a boolean!...
(tomorrow) ;-)
Thanks for the assist.

You could either do an INT(1) DEFAULT 0 or an ENUM('Y','N') to
make it easier on yourself.

I suppose I could instead place a string value of "0" in the query
statement, if bool false, perhaps?
I'll try that.

[PHP-DB] bool type (between MySQL and PHP)
Hello, I'm having some issues with bool's relating to MySQL. I am using: $tvar = true; $tvar = false; in PHP, but only the TRUE value gets accepted by the MySQL insert or update's. It appears MySQL sees the TRUE value as 1.. because that is what shows up.. and that MySQL throws an error when false because the query: UPDATE tablename SET vbool=$tbool parses to: UPDATE tablename SET vbool= which throws a syntax error. What is the best PHP practice when using bools with MySQL? Save 1's and 0's instead of true/false?
