named: [value name=field escaped=1 set=``new value'']
positional: [value field flag*]
HTML examples:
<PARAM MV="value name"> <INPUT TYPE="text" NAME="name" VALUE="[value name]">
Expands into the current value of the customer/form input field named by field. If flag is present, single quotes will be escaped with a backslash; this allows you to contain the [value ...] tag within single quotes. (It is somewhat better to use other quoting methods.) When the value is returned, any MiniVend tags present in the value will be escaped. This prevents users from entering MiniVend tags in form values, which would be a serious security risk.
If the set
value is present, the form variable value will be set to it and the empty
string returned. Use this to ``uncheck'' a checkbox or set other form
variable values to defaults. NOTE: This is only available in new-style tags, for safety reasons.
