Re: [PHP-DB] refresh the page on back
use the cache disable headers in HTML as well as PHP for the server side headers. pick any of the two methods. 1-HTML caching control: meta http-equiv=pragma content=no-cache / meta http-equiv=cache-control content=no-cache / meta http-equiv=cache-control content=must-revalidate / meta http-equiv=cache-control content=proxy-revalidate / meta http-equiv=expires content=Sat, 06 Dec 2003 1:00:00 GMT / 2-PHP server headers for caching control: // Date in the past header(Expires: Mon, 26 Jul 1997 05:00:00 GMT); // always modified header(Last-Modified: . gmdate(D, d M Y H:i:s) . GMT); // HTTP/1.1 header(Cache-Control: no-store, no-cache, must-revalidate); header(Cache-Control: post-check=0, pre-check=0, false); // HTTP/1.0 header(Pragma: no-cache); On Thu, 14 Oct 2004 12:19:27 +0530, balwantsingh [EMAIL PROTECTED] wrote: first of all excuse me for putting the non related question in this forum. but i am sure someone will help me. i want that whenever users press the browser back button, the page should be refreshed and than displayed. thanks for your help in advance. with best wishes balwant -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- M.Saleh.E.G 97150-4779817 -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP-DB] PHP versions - Development server live server...
I don't recall installing any optimising or encrypting extensions?? Are they perhaps installed with mySQL? How do I reinstall them, that is assuming I need them? -Original Message- From: M Saleh EG [mailto:[EMAIL PROTECTED] Sent: 14 October 2004 03:24 To: Peter Borcherds Cc: [EMAIL PROTECTED] Subject: Re: [PHP-DB] PHP versions - Development server live server... Seems that ur optimizing and encrypting extensions are not loaded properly. That's what it means. Okay, It might mean that you're old PHP's PHP.ini is still there and the new one is using it while it doesnt have the extensions files. check if those files are there... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP-DB] mysql error and resource ID:
See PHP manual Chapter 6. Types Strings
for an explanation of single double quotes.
From the doc:
If the string is enclosed in double-quotes (), PHP understands more escape
sequences for special characters
But the most important feature of double-quoted strings is the fact that
variable names will be expanded.
In your case it would be ' within .
$query = INSERT INTO MainTable (RecordID,UserID,.)
values(null,null,'$f1a','$f2a',...);

Quote as in string or quote as in 'string' ?
Those two confuse me.

Not much luck here on placing the
mysql_error($link);
I know the server and database is reachable. So I
imagine the error is happening in the query. I've
moved the $link around with no luck.

Yes, actually my apologies to everyone. I figured out the error. So , yep, I'm down to a problem with the date. The column is set to date. I'll go ahead and add the quotes.

[PHP-DB] Converting Date for mysql
I have one of those widget calendars.
Mysql keeps throwing back the date regardless of the
way I format it.
I'm passing session variables over to the database and
have tried quotes ' around the date as well.
Now I went ahead and changed this line:
$_SESSION['f3k'] = $_POST['DateAvailable'];
to
$_SESSION['f3k'] = date('Y-m-d',
mktime(0,0,0,substr(3,5,$_POST['newdate']),
substr(0,2,$_POST['newdate']),
substr(6,10,$_POST['newdate'])));
I now tried to pass 'newdate' into the database and
still rejected.
Any ideas ?

RE: [PHP-DB] Converting Date for mysql
did you look to see what the data format was? many of these calendars fill
in american dates (mm-dd-) and mysql prefers (-mm-dd)check to
see what the format is before you assign it to the session id...

[PHP-DB] How to optimize select of random record in DB ?
I made this code to pick a random record from a changeable number of
records in a given table.
I'm just curious if any of the more awake coders out there can see a way to
optimize this for better performance, since there's several other DB
queries on the same page.
$records = mysql_query(SELECT COUNT(*) AS count FROM persons) or
die('Unable to get record countbr'.mysql_error());
$totalcount = mysql_result($records,0) - 1;
$rndrecord = rand(0,$totalcount);
$personquery = mysql_query(SELECT personID FROM persons LIMIT
$rndrecord,1) or die('Unable to get random recordbr'.mysql_error());
$personID = mysql_result($personquery,0);
