There is a function called MM_findObj which does exactly what you

digress.
Below is the funtion, and whenever you want to refer to oddly named form
elements, you call MM_findObj('oddlyNamedFormElement[]') (and it returns
an object reference to the form element that you can use normally).
function MM_findObj(n, d)
{

There are several ways to do this. The simplest way is to authenticate
once and store a authentication flag in the session. You can set this
authentication flag to true if the log-in was sucesfull.
On the administration page, you an just access the flag to see if the
user is permitted (i.e. logged on). You can do this using the $_SESSION
super global, something like this:
(pseudo php code)
login.php
...
if ( authentication sucessfull ) /* username/password matched*/
{
$_SESSION['auth'] = true;
// redirect to admin page
}
else
{
Display login page with error.
}
...
admin.php
...
if ( $_SESSION['auth'] )
{
Show administration page.
}
else
{
Display login page with error.
}

Re: [PHP-DB] Problem Using Sessions. .
From the PHP help page on session_register() If your script uses session_register(), it will not work in environments where the PHP directive register_globals is disabled. I'm assuming since you compiled and installed PHP 5.0.4 that your register_globals is disabled. I wouldn't recommend enabling it to fix this problem. Instead use $_SESSION super global to register session data. So instead of: session_register(username); try this: $_SESSION['username'] = $username; /* TO SET */ $username = $_SESSION['username']; /* TO GET */ Hope this helps, Aman Shawn Singh wrote: Hey All, I'm fairly new to PHP Programming.

Re: [PHP-DB] Headers sent error msg on one server but not the other.... .
Check that there is no output generated before your script hits the
Header() function calls. The most common mistake I've noticed is that if
you require() or include() many files before you call Header(), and if
there is any content outside of the ?php ? tags in the includ()'ed
or require()'d files (eg. a carraige return at the end, or a space after
the ?.
Check for that and that should fix your problem.

The test server has reg globals = OFF and the production server has them

RE: [PHP-DB] retrieve enum values
Melanie,
Here's a function that will parse the SHOW COLUMNS query output and will
return an array of ENUM values, after you have the array it should be
easy to generate the html code you need.
The first two parameters are self explanatory (the table name and the
column name).
Hope this helps,
define(G_ENUM_COLUMN,4); // set this to 4 if you are using SET column
type, and 4 for ENUM column type.
/*
Return the SET or ENUM set of values.
$p_start can be 3 for SET... or 4 for ENUM...
*/
function get_set_column_values ( $p_table, $p_colname ) {
$result = mysql_query($query);
$arr = mysql_fetch_array(
doQuery( SHOW COLUMNS FROM $p_table LIKE '$p_colname';
)
);
$value = substr( $arr[1], G_ENUM_COLUMN );
eval( \$the_array = array $value; ); // let eval do all the
parsing work.
return $the_array;
}

Subject: [PHP-DB] retrieve enum values
Hi!
I have a column type enum in mysql.
At the moment the possible values are 1,2 and 3.
I make a form for my user to modify that value, something
like: select option value='1'1/option option
value='2'2/option option value='3'3/option /select
I may need to add a value 4 to the enum, and in that case I
would like to
avoid modifying the code.
I would like to know it it is possible to have something
like: select possible_enum_values from table ... and then
having a loop through these values. I can't select distinct
values in that column because one value may not
exist yet and I don't want to have fake records.
I found that in the mysql doc and was wondering if there is
an already
implemented php function intsead of having to parse:
If you want to determine all possible values for an ENUM
column, use SHOW
COLUMNS FROM tbl_name LIKE enum_col and parse the ENUM
definition in the
second column of the output.
Any idea?

RE: [PHP-DB] Re: paginating : optimising queries
I've run in to this situation before. And it turns out that the extra pre-count query is not worth it. So the steps become: 1) Do your main query and fetch the results. 2) Use the count of results obtained in step 1. 3) Calculate pagination numbers. 4) Use array_slice to limit the results to a page window calculated in step 3.
