[PHP-DB] big sessions problem - page refusing to load, but will if I skip the logonpage
I have a logon screen that starts a session for several other pages and it
has been working great,
over the weekend something happened. I checked the site from home and
after login the main
page would not load, just a white screen and view source showed absolutely
nothing. Now I'm in the
office and looking at the source code and I don't see anything wrong,
nothing changed. I can load the
pages by skipping the logon and typing in the complete url manually and
they all load just fine, soon
as I try to use the logon screen the first main page after it will not
load, if I enter the full url to another
protected page it will load, then I can use the links for the main page
and it too will now load. Just after
the logon, the main page will not load. I have tried this with both my own
login and a users login and
it is happening to all.
Any idea what could be causing this? I've gotta get this fixed ASAP,
perminently, this is a business web
site. The code for the login screen and the main page are pasted below.

I don't necessarely need to have each page as a number at the bottom, just the previous and next links.

Re: [PHP-DB] Next N Interface
I did something like this with a photo gallery I made. The approach I took is
the execute a query, get the number of rows, and divide that number by how ever
many records I wanted on that page. Then that would give me the number of total
pages I would have for my navigational links at the bottom. Then I would pass a
page number from page to page and multiply this by the number of records which
would give me the first record to display from the same query. Soem sample
code: (I displayed 4 pictures/records per page)
$num_rows = mysql_num_rows($result);
//Check to see if any rows are present
if ($num_rows = 0)
{
echo centerh2No Pictures Available in this Album/h2/center;
exit(1);
}
$x = ($num_rows/4);
$y = intval($x);
if ($x $y)
{
$num_pages= $y+1;
}
else
{
$num_pages= $x;
}

know of a way to eliminate the database field and still show the status
of the values in a web table, please point me in the right direction. I

I don't see where you put your blank table column.
I am guessing it might be somewhere within this for loop:
for ($i=0; $i $num_tables; $i++) {
echo(centerh3 $arr_tablenames[$i] /h3/center);
echo('table align=center border=1tr');
$result = mysql_db_query($dbname, select * from
$arr_tablenames[$i], $id_link);
for ($ii=0; $ii $arr_num_fields[$i]; $ii++) {
echo(th);
echo $hash_field_names[$i][$ii];
echo(/th);
}
echo(/trtr);
$number_of_rows = @mysql_num_rows($result);
for ($iii = 0; $iii $number_of_rows; $iii++) {
$record = @mysql_fetch_row($result);
for ($ii=0; $ii $arr_num_fields[$i]; $ii++) {
echo(td);
echo $record[$ii];
echo(/td);
}
echo(/tr);
}
echo(/table);
}
If that's the case, all you need to do is, let's pretend $table_value
holds
the table value you need to determine the background color:
echo td;
if ($table_value 5)
{
echo bgcolor = \#99\; // whatever color you want
}
else if ($table_value = 5 $table_value 10)
{
echo bgcolor = \#88\; // another color
}
else// if no value matched
{
echo ; // close td tag
}

If the table's background color will be set when the page is first
loaded,
you can just use the bgcolor attribute of td tag.
If you want to dynamically change the background color, you'll need to
combine your page with javascript.

Re: [PHP-DB] Next N Interface
How about appending LIMIT _GET[startrow],5 to the end of your query. The first parameter to LIMIT is the start position and the second is the number of rows to return.

Re: [PHP-DB] Next N Interface
That would actually work for just getting a certain number of records from a query, but you would have to execute another query to figure out the navigational links he said he wants on the bottom...like google has, 1 2 3 4 5 . So, when I attacked it I figured one query is better then two even if it returns a whole bunch of records in the result that you are not using for that page. How is that for performance? which would be better? Or even, is there an alternative way to figureing out how many records are in a database? Always more then one way to skin a cat. -Brad Mark Lee wrote: How about appending LIMIT _GET[startrow],5 to the end of your query.

How is that for performance? which would be better? Or even, is there an alternative way to figureing out how many records are in a database? Always more then one way to skin a cat. Use two queries. A count(*) query and a LIMIT query to only return X rows. If you have a smaller table, it might be okay to do it with on and seek the rows you want, but it's inefficient and not scalable for large tables. Previous/Next links are pretty simple with MySQL. Just pass a $page variable between pages. Increment it with Next, decrement it with Previous. Then, use it in your query like this: $result1 = mysql_query(SELECT COUNT(*) FROM your_table WHERE ... ); $records = mysql_result($result,0); $num_per_page = 5; $start = $page * $num_per_page; $num_pages = ceil($records / $num_per_page); $result = mysql_query(SELECT * FROM your_table WHERE ... LIMIT $start, $num_per_page); Add in a little logic so $page isn't below zero and doesn't go above your max pages, and you're golden... ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ryan,
I understand you want to display the results of a db query in an html
table. Maybe I misunderstand but it seems that this shouldn't be done by
fiddling with the database table; fiddle with the html table instead
open mysql server
do select $result
start while loop on mysql-fetch-array($result) {
set
$summedfields = (sum field values);
if ($summedfields == 2) {
$bgclr=red;
}
else {
$bgclr=blue;
}
if ($blankfield == NULL) {
$blankfield = img src='image.gif' etc;
}
iterate on table row
use $blankfield and $bgclr as values the html table data cells
eoe

RE: [PHP-DB] Compare time functions
Could anyone help me to figure out how to write a piece of code that
says
if the time now time( ) is greater than 1 hour of the time( time
stored
in the database) do something.
I have a script that gets the time as of now and I also have the time
of
(lets say then) stored in a database.
how would I write the code to say if the old time is greater than 1
hour do
something?
I need to compare the 2 time( ) functions.
$time1 = current server time
$time2 = server time stored in the database
if ($time1 is = 1 hour of $time2)
{
execute code
}
How would one go about comparing these two time functions?
Well, if you want to do the comparison in PHP, you can select out all of
the rows and loop through them all. Use UNIX_TIMESTAMP(column_name) in
your query to get out the unix timestamp of the date column, instead of
the mysql format. Then..
$now = time();
if($now - $db_time 3600)
{
//more than an hour old
}
You could do it in your query like this:
SELECT * FROM your_table WHERE db_time_column NOW() - INTERVAL 1 HOUR;
That'll return all rows that have a db_time_column that's more than an
hour old. Adapt that to an update or delete query and you're good to go.

[PHP-DB] session_destroy() problem.
Ok. What is the best way to destroy a session. I have a logout page which is supposed to destroy the session but it doesn't seem to be working. After the user logs out they are take back to the log in page, which is all fine and good. But if the user tries to go to a restricted page they are let in. This is the code for my logout page. session_start(); setcookie(session_name(),,,/); session_unset(); session_destroy(); header(Location: index.php); any ideas? //Ryan -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
