128 Chapter 6: Extending ColdFusion Pages with CFML Scripting
For example, the following example loops through a query in CFScript:
...
<cfscript>
// Loop through the qGetEmails RecordSet
for (x = 1; x LTE qGetEmails.RecordCount; x=x+1) {
This_id = qGetEmails.Emails_id[x];
This_Subject = qGetEmails.Subject[x];
This_RecFrom = qGetEmails.RecFrom[x];
This_SentTo = qGetEmails.SentTo[x];
This_dReceived = qGetEmails.dReceived[x];
This_Body = qGetEmails.Body[x];
... // More code goes here.
}
</cfscript>
Using CFScript statements
The following sections describe how to use these CFScript statements:
• Using assignment statements and functions
• Using conditional processing statements
• Using looping statements
Using assignment statements and functions
CFScript assignment statements are the equivalent of the
cfset tag. These statements have the
following form:
lval = expression;
lval is any ColdFusion variable reference; for example:
x = "positive";
y = x;
a[3]=5;
structure.member=10;
ArrayCopy=myArray;
You can use ColdFusion function calls, including UDFs, directly in CFScript. For example, the
following line is a valid CFScript statement:
StructInsert(employee,"lastname",FORM.lastname);
cftry, cfcatch try and catch statements
cfcookie Direct assignment of Cookie scope memory-only variables. You cannot
use direct assignment to set persistent cookies that are stored on the
user’s system.
cfobject CreateObject function
