10.3.2.4 Using Web context variables with FORMS
The Web context variables provide the easiest way to use FORM fields when the FORM is posted.
As described below, there is a special form call ExeScriptForm that allows to request execution of a script command.
Example:
• When the form is posted, the "goto UseForm" request is posted in the BASIC queue.
• If other fields are added in this form, there content can be accessed using Web context variables.
Example:
And the BASIC contains the following code at UseForm label:
Warning:
That Web context variable must be lowercase.
<form method="POST" action="/rcgi.bin/ExeScriptForm">
<input type="hidden" name="Command" value="goto UseForm">
</form>
<form method="POST" action="/rcgi.bin/ExeScriptForm">
<input type="text" name="edit1" size="20">
<input type="hidden" name="Command" value="goto UseForm">
</form>
UseForm:
REM save Edit1 parameter
A$ = edit1!
PRINT "Edit1 value entered was:";A$
