Once one of the buttons is pressed, the equivalent of a web form is submitted to the UnForm server, to run the same rule set that contains the detect and button commands (-f and –r are used, along with any args options and a hard-coded "-p pdf"). The following values are available in the cgi$ template:
cgi.button$
|
Returns button title, indicating which button was pressed.
|
cgi.selected$
|
Returns text of a text field associated with the button.
|
cgi.panel$
|
Returns the name of the active panel when the button was pressed, or "*" if no panels are defined.
|
cgi.data$
|
Returns all the panels and text fields in an INI file format. Panel titles are used as section headers, and text and clipboard field text boxes are returned in name=value format. If no panels are provided, a single section header [*] is supplied.
This format allows multiple fields of data to be submitted and interpreted by the rule set, by using the getinival() function, passing cgi.data$ as the first argument. For example, name$=getinival(cgi.data$, "CustPanel", "Name") would set name$ to the value of the Name field in the CustPanel panel.
|
cgi.parsevalue$
|
Returns the value of the clipboard or window title in cases where the parsevalue option is specified. Note that if this value is present, DTC is submitting a request for reformatting of this data. It is not a result of the user pressing a DTC submit button. No cgi.selected$ or cgi.data$ is sent.
|
Use the prejob code block to interpret these items, and generate a cgiresponse$ string value. This value is returned to DTC for processing. DTC interprets the response in these ways:
| • | http: or https: prefix performs shell launch to display URL in the default browser |
| • | error: message text (use \n for CRLF) displays an error style message box |
| • | message: message text (use \n for CRLF) displays an information style message box |
| • | other text renders in local browser control, and assumes HTML content |
The webapi object can be used to generate http responses. Note these http values can also be used in <a href=> tags in a pure html response.
If no cgireponse$ is available, the print job result is returned instead, allowing artificial print jobs to execute (by generating text pages in a prejob code block, and allowing normal rule set processing to handle the job). The print job will be in PDF format.
