Syntax
$WBA$TextToBeAppended

Description
This is a form field value prefix for appending text to fields of string types (text, memo, etc.). When WBSP engine receives a WBF_tablefieldname form field value with this prefix for database table field of string type, instead of replacing the old value with new one, it will append the new value to the existing one (so new value stored in the database is OldDatabaseTableFieldValueNewFormValue)

Here's an example:

<!--
[FormFields]
WB_BaseName=biblioA.mdb
WB_RcdSet=Titles
WB_Command=Q
-->
<!--WB_BeginTemplate-->
<html>
<body>
<!--WB_BeginDetail-->
<form action="TitlesUpdate.wbsp" method="POST">
<input type="hidden" name="WBF_Title" value="$wba$ - second edition">
<input type="hidden" name="wbf_isbn" value="$wbf[isbn]">
$wbf[Title]<br>
<input type="submit" name="sUpd" value="Second edition">
</form>
<!--WB_EndDetail-->
<center>$wbnavigator</center>
</body>
</html>
 

After running this example (and pressing the "Second edition" button), text  - second edition will be appended to the field Title in updated record of table Titles.
