<section begin="desc" />Value of isindex field<section end="desc" />
$Web_IsIndex_Parm retrieves the value of an isindex field in a URL.
Since isindex fields are more commonly called "URL parameters," you may want to use the synonym for this $function, $Web_URL_Parm (see $Web_URL_Parm).
Syntax
<section begin="syntax" /> %STRING = $Web_IsIndex_Parm( fieldname, occurrence, - start, length ) <section end="syntax" />
$Web_IsIndex_Parm takes four arguments and returns a string, or null for any error condition.
| fieldname | The name of the isindex field, returned by $Web_IsIndex_Name. Required argument if occurrence not specified, otherwise optional. |
|---|---|
| occurrence | The occurrence number of an isindex field, or the occurrence number of the isindex field matching fieldname, if fieldname is specified. This is an optional argument if fieldname is specified; otherwise it is required. |
| start | Starting position within the field. This is an optional argument which defaults to 1. |
| length | Length to return. This is an optional argument, provided in case an isindex field exceeds 255 bytes. The length of an isindex field can be determined with $Web_IsIndex_Len. The default is the length of the isindex field. |
This example places the value of each isindex field in a URL into a User Language %variable of the same name.
* Stash the form values in matching fields. %CUST_NAME = $Web_IsIndex_Parm('CUST_NAME' ) %CUST_NUM = $Web_IsIndex_Parm('CUST_NUM' ) %ORDER_NUM = $Web_IsIndex_Parm('ORDER_NUM' ) %ORDER_DATE = $Web_IsIndex_Parm('ORDER_DATE' ) %ORDER_ITEM = $Web_IsIndex_Parm('ORDER_ITEM') %ORDER_ITEM2 = $Web_IsIndex_Parm('ORDER_ITEM', 2)
