Layers

Layers and other tricks

1) Layer control via behaviors window:

One of the most powerful Dreamweaver web techniques is layer control via the Behaviors window

First, create a layer or set of layers you want to pop up. Insert / layout objects / layer (Or the Layout bar on the insert window also has a "draw layer" button"
Secondly, i nsert a rollover or mapped image of your choice. The animated gif is OK, but any image or set of images will do.
Click on this image or image map so that it is highlighted.
Open the Behaviors window and click on the plus sign ( + ) then pull down to “Show- Hide Layers”
A new dialogue box will appear with a list of named layers. Click on each layer and then click on the button indicating Show or Hide. All layers should either be shown or hidden. Then click OK.
Test in browser.

2) Meta Refresh :

<head>
<meta HTTP-EQUIV="Refresh"
content="1; URL=http://www.radford.edu/~login/alternative.html">
</head>
<body>
</body>
</html>

/* Note 1 is the time for refreshing the page in seconds */

3) Includes :

Suppose you have a client who wants to upload simple text files but doesnt want to



At our university, we might have a virtual include for a file that does this:



There are also a host of "server side includes" such as :

 or

<A HREF="">BACK BUTTON</A>

Here are some others from: http://bignosebird.com/sdocs/echo.sh

AUTH_TYPE client authorization method if any
CONTENT_LENGTH size of input posted from client
CONTENT_TYPE MIME type of content
DATE_GMT The current GMT (greenwich, UK) can be formatted using #config
DATE_LOCAL current time/date, can be formatted using #config
DOCUMENT_NAME document name that was requested
DOCUMENT_URI URL of the document
LAST_MODIFIED document modified date, can be formatted using #config
PAGE_COUNT number of accesses to current document since server was brought on line
HTTP_REFERER URL of the document the client came from
REMOTE_ADDR Numeric IP address of the client
REMOTE_HOST domain name of the client (DNS option must be active on server)
REMOTE_USER ID of user, rarely ever found
REQUEST_METHOD HTTP method: GET OR POST
SERVER_NAME server hostname (i.e., www.bignosebird.com)
SERVER_PORT the port used by httpd (usually 80)
SERVER_PROTOCOL Which version of Httpd compliance
SERVER_SOFTWARE The name of the server software, i.e., apache 1.2.5
TOTAL_HITS total pages served by server since brought on line

You can control the exact appearence of your time and date information by setting the timefmt using a config such as the one below. Just include this config before the actual include that calls the date.

Will give you a date such as 02/17/97
