Re: [PHP-DB] Problems with mysql_num-rows()
The variables are not being expanded. As a minimum, you need to escape the single quotes.
$query = "SELECT * from user where name=\'$userid\' and
pass=password(\'$password\')"
Alternatively, you can concatenate the expanded variables.
$query = "SELECT * from user where name='".$userid."' and
pass=password('".$password."')"
Good luck,
Doug

This one works OK:

$num_rows = mysql_num_rows($result);
What is wrong and how can I use mysql_num_rows when the query include
"WHERE"
A fast response will be very much appreciated.

RE: [PHP-DB] Problems with mysql_num-rows()
Very simply, either your connection is messed up, you are not getting a
result set back or there is an error in your sql
try this:
$result = mysql_query($query, $link) or die ("failed because
".mysql_error());
then start debugging

For example (for this particular problem) if you suspect PHP is calculating the dates incorrectly then a few lines of code showing the date calculations would be sufficient.

Use mysql_error().

[PHP-DB] selective query?
I'm tweaking my internet speed tester thingamabob
(http://www.dibcomputers.com/bandwidthmeter/index.php) and am rather
stumped. Currently, I'm grouping together all results from each domain (all
results from, say, adelphia.net are averaged and displayed as one, etc) and
to that end I stopped displaying IP address results. Is there a way I can
do a selective group? For example, all results from 11.22.33.44 should be
averaged and grouped together, and all results from adelphia.net should be
averaged and grouped as well.
Here's the code I've got that displays all results:
echo "Average speeds of each domain tested:";
$mongo = @mysql_query ("SELECT
substring_index(name,'.',-2),ROUND(MIN(speed),1),ROUND(AVG(speed),1),ROUND(M
AX(speed),1) FROM `readings` WHERE name <> ip GROUP BY
substring_index(name,'.',-2) ORDER BY substring_index(name,'.',-2) ASC");
echo "DomainLowest SpeedAverage
SpeedHighest Speed\n";
while ($mongorow = mysql_fetch_array($mongo, MYSQL_NUM))
{
if($bg=='#dd') $bg='#ff' ;
else $bg='#dd' ;
echo "http://www.$mongorow[0]\";
target=\"new\">$mongorow[0]$mongorow[1]$mongorow[2]$mongorow[3]\n";
}
echo "";
Any ideas?
TIA,
Dan

[PHP-DB] Something wierd with time() and curdate()
There is something wierd going on over here...
I have a date field, datum, in mysql that I cast to a timestamp and check against
time().
If the datum value is more than one day old the table finds a new random row and sets
the datum field to CURDATE().
Now, this has worked for two years now, but today the script suddenly finds a new
random row each time the script is run...
I've notice this just after 11 pm today.
As I can see from some debugging time() allways returns a higher value than the
timestamp + 86400...
Have I missed something in this script for the last couple of years or is there a bug
somewhere? Could it have something to do with the fact that we turned the time back
one hour last night?
This is the code btw:
function bibelvers($link_id, $color = "white") {
$myBible = new Bible($link_id, "FB");
$myBible->set_delimiters("span","p","bibelversnum","text");
$vers_nr = "";
$vers_txt = "";
$reset = false;
$q = "SELECT vers,textkod,UNIX_TIMESTAMP(datum) as datum FROM dagensvers WHERE visad
= 'NU'";
$result = mysql_query($q, $link_id);
if (mysql_affected_rows($link_id) == 1) {
$v = mysql_fetch_object($result);
if (time() > ($v->datum + ONEDAY)) {
mysql_free_result($result);
$q = "SELECT vers,textkod FROM dagensvers WHERE visad = 'NEJ'";
$result = mysql_query($q, $link_id);
$rows = mysql_affected_rows($link_id)-1;
if ($rows >= 0) {
mysql_data_seek($result, rand(0,$rows));
$v = mysql_fetch_object($result);
$q = "UPDATE dagensvers SET visad = 'JA' WHERE visad = 'NU'";
mysql_query($q, $link_id);
$q = "UPDATE dagensvers SET datum = CURDATE(), visad = 'NU' WHERE textkod =
'".$v->textkod."'";
mysql_query($q, $link_id);
}
else { $reset = true; }
}
}
else { $reset = true; }
if ($reset) {
$q = "UPDATE dagensvers SET visad = 'NEJ' WHERE visad = 'JA'";
mysql_query($q, $link_id);
$q = "SELECT vers,textkod FROM dagensvers WHERE visad = 'NEJ'";
$result = mysql_query($q, $link_id);
$rows = mysql_affected_rows($link_id)-1;
mysql_data_seek($result, rand(0,$rows));
$v = mysql_fetch_object($result);
$q = "UPDATE dagensvers SET visad = 'NEJ' WHERE visad = 'NU'";
mysql_query($q, $link_id);
$q = "UPDATE dagensvers SET datum = CURDATE(), visad = 'NU' WHERE textkod =
'".$v->textkod."'";
mysql_query($q, $link_id);
}
$vers_nr = $v->vers;
$vers_txt = $v->textkod;
$myBible->str_vers_format($vers_txt, false, false);
$str = "\n".
"\t DAGENS BIBELVERS | ".$vers_nr."\n".
"\t\n".
"\t\t".
$vers_txt.
"\t\t\n".
