Server behavior techniques 373

This server behavior no longer works correctly because only one parameter is named total.

To solve this problem, make sure that there is a parameter with a unique value and can be

used to match the participants. In the following example, you could make the

total variable

name unique using the column name:

<% itemPrice_total = Recordset1.Fields.Item("itemPrice").¬

Value * 1.0825 %>

<% salePrice_total = Recordset1.Fields.Item("salePrice").¬

Value * 1.0825 %>

<html>

<body>

The total (with taxes) is $<%=itemPrice_total%>

Sale price (with taxes) is $<%=salePrice_total%>

</body>

</html>

The search patterns now uniquely identify and match the participants.

Search pattern resolution

Dreamweaver supports the following actions by using the participant

searchPatterns functionality:

■ File transfer dependency

■ Updating the file paths for any file reference (such as those for include files)

When Dreamweaver creates server models, it builds lists of patterns by scanning all the

participants for special

paramNames attributes. To find URLs to check file dependency and to

fix the pathname, Dreamweaver uses each

searchPattern tag in which one of the

paramNames attribute ends with _url. Multiple URLs can be specified in a single

searchPattern tag.

For each translator

searchPattern tag that has a paramNames attribute value that ends with

_includeUrl, Dreamweaver uses that searchPattern tag to translate include file statements

on the page. Dreamweaver uses a different suffix string to identify include file URLs because

not all URL references are translated. Also, only a single URL can be translated as an include

file.

In resolving a

searchPatterns tag, Dreamweaver uses the following algorithm:

1. Look for the whereToSearch attribute within the searchPatterns tag.

2. If the attribute value starts with tag+, the remaining string is assumed to be the tag name

(no spaces are allowed in the tag name).
