Should This Newbie Learn From Dreamweaver?

First of all - I know this is an entirely subjective question, and I know
there's no single approach to learning this technology. I'm just looking for
a few hints from seasoned professionals basically whether Dreamweaver
verbose code (at least it looks like that to me at this beginning point) is
all 'needed & necessary'...
I have a background using ColdFusion, however I am new to php / mySQL.
I am caught between two learning approaches:
1 - I know that generally, it is better to build my knowledge from the
'bottom up' - coding by hand from books and such etc. - and so far I have
been doing that with php and mySQL. Slowly I am getting there. Php is quite
powerful and impressive.
2 - Dreamweaver cs3 is pretty cool. Creating recordsets - dynamic data -
updating records etc. is pretty seductive it seems to work well.
A few questions:
One of my issues is that the Dreamweaver code that gets created seems quite
verbose and somewhat complex (like using switch & case in a simple query
listed below...), therefore even harder for this newbie to try to learn
from. My question is this: Is this Dreamweaver code actually all
modern/necessary (vs a 'simple approach') - or is it way over the top?
Without getting too detailed:
- If in fact you folks say that most of the DW approach (for those that have
seen it) is 'necessary' & 'the right way to do things' - then I will be
happy to use it and try to figure out some of its complexities . But, if you
think that DW is over the the top ('...I don't use all that suff - I do a
query in just a few lines!') ... then I'll just start with the 'bottom up -
code by hand - do it yourself simple approach'.
BTW: if anyone wants to see more DW code - email me off-list - I'll be happy
to send more examples... (I don't want to clog up this cool list)
BTW: I also tried a happy medium - simplifying the DW code - however that
will break its usefulness in DW - and other DW interface items stop working,
so I guess that's not an option right now.
Interested in your thoughts... Dave
------------------------
Example get recordset query w DW:
<?php require_once('../Connections/weblink.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "",
$theNotDefinedValue = "")
{
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
$theValue = function_exists("mysql_real_escape_string") ?
mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" :
"NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue :
$theNotDefinedValue;
break;
}
return $theValue;
}
}
$colname_get_Recordset1 = "-1";
if (isset($_SESSION['mem_id'])) {
$colname_get_Recordset1 = $_SESSION['mem_id'];
}
mysql_select_db($database_weblink, $weblink);
$query_get_Recordset1 = sprintf("SELECT * FROM tbl_test WHERE mem_id = %s
ORDER BY mem_id ASC", GetSQLValueString($colname_get_Recordset1, "int"));
$get_Recordset1 = mysql_query($query_get_Recordset1, $weblink) or
die(mysql_error());
$row_get_Recordset1 = mysql_fetch_assoc($get_Recordset1);
$totalRows_get_Recordset1 = mysql_num_rows($get_Recordset1);
