Sorting a Dynamic Table - is there a tutorial yet?

I'm still scratching my head over this. I've read so much stuff that my brain
hurts, but I can't put it all together. I need a Dreamweaver tutorial that
picks up where Trio Motors left off - one that tell me, step by step, how to
assign the tables to a document (or whatever) and how to sort the document.
It's so confusing to me without the baby steps.

Help! Does such a tutorial exist?

Only people who have done that tutorial would really know where it left off
(I haven't). I think you're going to need to explain in more detail what you
know how to do and what you're trying to figure out how to do.

What server model (ASP, ColdFusion, PHP..?)

Thanks Peter, but surely there's a way to learn this without having to pay for
the lesson? Or buy an extension?
Patty, this is kinda continued from this thread http://tinyurl.com/8hfha -
from the General Discussion here.

I can only work with PHP ... and perl, maybe? - my host/server can't handle
ASP or ColdFusion.
Operating system Linux
Apache version 1.3.33 (Unix)
PHP version 4.3.10
MySQL version 4.0.25-standard

I know how to create recordsets and dynamic tables in Dreamweaver. I need to
be able to sort the tables though. An example of what I've got is here

http://www.lady18wheels.com/phpbb_data/by_userID_02.php

It's pulling from the database of my phpBB2 message board.

The code looks like this:

<?php require_once('Connections/conn01.php'); ?>
<?php
$currentPage = $_SERVER["PHP_SELF"];

$maxRows_Recordset1 = 100;
$pageNum_Recordset1 = 0;
if (isset($_GET['pageNum_Recordset1'])) {
$pageNum_Recordset1 = $_GET['pageNum_Recordset1'];
}
$startRow_Recordset1 = $pageNum_Recordset1 * $maxRows_Recordset1;

mysql_select_db($database_conn01, $conn01);
$query_Recordset1 = "SELECT * FROM phpbb_users ORDER BY user_id DESC";
$query_limit_Recordset1 = sprintf("%s LIMIT %d, %d", $query_Recordset1,
$startRow_Recordset1, $maxRows_Recordset1);
$Recordset1 = mysql_query($query_limit_Recordset1, $conn01) or
die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);

if (isset($_GET['totalRows_Recordset1'])) {
$totalRows_Recordset1 = $_GET['totalRows_Recordset1'];
} else {
$all_Recordset1 = mysql_query($query_Recordset1);
$totalRows_Recordset1 = mysql_num_rows($all_Recordset1);
}
$totalPages_Recordset1 = ceil($totalRows_Recordset1/$maxRows_Recordset1)-1;

$queryString_Recordset1 = "";
if (!empty($_SERVER['QUERY_STRING'])) {
$params = explode("&", $_SERVER['QUERY_STRING']);
$newParams = array();
foreach ($params as $param) {
if (stristr($param, "pageNum_Recordset1") == false &&
stristr($param, "totalRows_Recordset1") == false) {
array_push($newParams, $param);
}
}
if (count($newParams) != 0) {
$queryString_Recordset1 = "&" . htmlentities(implode("&", $newParams));
}
}
$queryString_Recordset1 = sprintf("&totalRows_Recordset1=%d%s",
$totalRows_Recordset1, $queryString_Recordset1);

How do you want to sort the table?

You can do it via PHP and a list/jump menu.

Here's the idea.

In your SQL SELECT statement you can specify how to sort the recordset.
Make the SORT part depend on a fieldname variable. Make the column heads
link to the same page and pass the fieldname via a URL parameter, e.g.,

<a href="thispage.php?fieldtosortby">

Make the page use that URL variable in the SQL SORT clause, e.g.,

SELECT * FROM tablename SORT variable ASC

(What are the quote tags here?)

Murray said, "Here's the idea. In your SQL SELECT statement you can specify
how to sort the recordset. Make the SORT part depend on a fieldname variable.
Make the column heads link to the same page and pass the fieldname via a URL
parameter, e.g., <a href="thispage.php?fieldtosortby"> . Make the page use
that URL variable in the SQL SORT clause, e.g., SELECT * FROM tablename SORT
variable ASC"

Bless your heart Murry; you must have the patience of Job. I appreciate it.

OK. I think I don't understand what a fieldname variable is.

In a table, I have headers and fields, right?
Like the headers are user_id; user_lastvisit; user_regdate; and user_posts.
I could have named them anything, but this is what Insert > Application
objects > Dynamic data > Dynamic table defaulted to (I think.)

The field names are
{Recordset1.user_id} - written like - <?php echo
$row_Recordset1['user_id']; ?>
{Recordset1.user_lastvisit} - written like - <?php echo
$row_Recordset1['user_lastvisit']; ?>
{Recordset1.user_regdate} - written like - <?php echo
$row_Recordset1['user_regdate']; ?>
{Recordset1.user_posts} - written like - <?php echo
$row_Recordset1['user_posts']; ?>

Am I right so far?

BTW - I thought I was on the brink of discovery when I posted this thread at
the phpBB forums: http://www.phpbb.com/phpBB/viewtopic.php?t=352655 . If I
could just post graphics here... .

And I found this in the Using Dreamweaver help section (of my software):

Creating a URL parameter to pass to the confirmation page (PHP)
"The links on the results page (see Creating links to a confirmation page
(PHP)) not only have to open the confirmation page, they must pass the ID of
the record the user wants to delete. The confirmation page will use this ID to
find the record in the database and display it.
You must pass the record ID to the confirmation page with a URL parameter.
This section describes how to create a URL parameter to pass the record ID to
the confirmation page.
To create the URL parameter:
Select the delete link on the results page.
If Live Data is turned on, select the link in the first row.
In the Link field in the Property inspector, add the following string at the
end of the URL:
?recordID=<?php echo $row_recordsetName['fieldName']; ?>
The question mark tells the server that what follows is one or more URL
parameters. The word recordID is the name of the URL parameter (you can make up
any name you like). Note the name of the URL parameter because you'll use it in
the confirmation page later.
The expression after the equal sign is the value of the parameter. In this
case, the value is generated by a PHP expression that returns a record ID from
the recordset. A different ID is generated for each row in the dynamic table.
In the PHP expression, replace recordsetName with the name of your recordset,
and replace fieldName with the name of the field in your recordset that
uniquely identifies each record. In most cases, the field will consist of a
record ID number. In the following example, the field consists of unique
location codes:
confirmDelete.php?recordID=<?php echo $row_rsLocations['CODE']; ?>
When the page runs, the values of the recordset's CODE field are inserted in
the corresponding rows in the dynamic table. For example, if the Canberra,
Australia, rental location has the code CBR, then the following URL will be
used in the Canberra row in the dynamic table:
confirmDelete.php?recordID=CBR
Save the page.
After creating a dynamic URL parameter for the delete links, the next step is
to display the record on the confirmation page. See Displaying the record on
the confirmation page (PHP)."

Does this sound like what I'm trying to do? LOL! (Please forgive my
ignorance.)
Thanks for your time.

You have records and fields. Fields are the columns and records are the
rows.

Those are the fields.

> The field names are
> {Recordset1.user_id} - written like - <?php echo

Actually that is the datum that is contained in the field called "user_id"
as selected in Recordset1.

> Am I right so far?

Sorta. 8)

But I will need to take this up again tomorrow morning. Duties call! 8)

I just wanted to know what the quote tags are so that I could copy/paste
text, and then put the quote tags around the text. I was trying to use <quote>
</quote> but I see what they are now.

Heh - maybe someone else can jump in. I'm out until next week....

Sorry.

But I'll check back to make sure you aren't hanging.

Not really. That text descibes what is needed to select a record for deletion.
Really, if you are trying to achieve something above and beyond what the server
behaviours provide, you are going to have to learn the programming language you
are working with. Just hacking some bits and pieces together is going to result
in code that will be difficult to maintain and troubleshoot.

Also, if the recordset is large and/or the query complex, you may want to
think about sorting the recordset results, rather than executing another select
everytime the user sorts a column.
