Value of form field to longstring
$Web_Form_Parm_Lstr retrieves the value of an HTML form field as a longstring.
$Web_Form_Parm_Lstr takes two arguments and returns a longstring or null for any error condition.
Syntax
%string = $Web_Form_Parm_Lstr( name, [occurrence] )
Syntax terms
| name | The name of the form field, returned by $Web_Form_Name. Required argument if occurrence is not specified, otherwise optional. |
|---|---|
| occurrence | The occurrence number of a form field, or the occurrence number of the form field matching name, if name is specified. This is an optional argument if name is specified; otherwise it is required. |
Usage notes
- $Web_Form_Parm_Lstr works much like $Web_Form_Parm, except for the following:
- It can return more than 255 bytes of data into a Longstring.
- It causes request cancellation if the result would be truncated, either on assignment to a target STRING %variable, or as input to a STRING $function argument or subroutine parameter.
- It does not have position and length arguments (arguments 3 and 4).
Examples
If you have an HTML form defined as follows:
<form method="POST" action="myUrl">
Foo:<input type="text" name="foo" size="20">
Bar:<input type="text" name="bar" size="20">
<input type="submit">
</form>
The following will retrieve the values of the Foo and Bar fields into longstrings called %foo and%bar.
%foo = $web_form_parm_lstr('FOO') %bar = $web_form_parm_lstr('BAR')
