The initial set of attributes is obtained from $argstr, a CGI query string, or $ARGV[0]. All the values are run through unescape to undo any URI encoding. The version and dbversion attributes are set to hardcoded values; action, nextsub, path, script, and login are filtered to remove some dangerous values. Both menubar and lynx are set if path matches lynx. $form->error may be called to deny access on some attribute values. =cut sub new { my $type = shift; my $argstr = shift; read( STDIN, $_, $ENV{CONTENT_LENGTH} ); if ($argstr) { $_ = $argstr; } elsif ( $ENV{QUERY_STRING} ) { $_ = $ENV{QUERY_STRING}; } elsif ( $ARGV[0] ) { $_ = $ARGV[0]; } my $self = {}; %$self = split /[&=]/; for ( keys %$self ) { $self->{$_} = unescape( "", $self->{$_} ) } if ( substr( $self->{action}, 0, 1 ) !~ /( |\.)/ ) { $self->{action} = lc $self->{action}; $self->{action} =~ s/( |-|,|\#|\/|\.$)/_/g; $self->{nextsub} = lc $self->{nextsub}; $self->{nextsub} =~ s/( |-|,|\#|\/|\.$)/_/g; } $self->{login} =~ s/[^a-zA-Z0-9._+\@'-]//g; $self->{menubar} = 1 if $self->{path} =~ /lynx/i; #menubar will be deprecated, replaced with below $self->{lynx} = 1 if $self->{path} =~ /lynx/i; $self->{version} = "SVN Trunk"; $self->{dbversion} = "1.2.0"; bless $self, $type; if ( $self->{path} ne 'bin/lynx' ) { $self->{path} = 'bin/mozilla'; } if ( ( $self->{script} ) and not List::Util::first { $_ eq $self->{script} } @{LedgerSMB::Sysconfig::scripts} ) { $self->error( 'Access Denied', __LINE__, __FILE__ ); } if ( ( $self->{action} =~ /(:|')/ ) || ( $self->{nextsub} =~ /(:|')/ ) ) { $self->error( "Access Denied", __LINE__, __FILE__ ); } for ( keys %$self ) { $self->{$_} =~ s/\N{NULL}//g } if ( ($self->{action} eq 'redirect') || ($self->{nextsub} eq 'redirect') ) { $self->error( "Access Denied", __LINE__, __FILE__ ); } $self; } =item $form->debug([$file]); Outputs the sorted contents of $form.

If values are passed into this function, only those $form values are output. If no values are passed in, all $form values are output as well as deleting $form->{header}. Values from the $form object are run through $form->quote, whereas keys/names are not.

If a CGI environment is detected, this outputs an HTTP and HTML header section if required, and displays the message after running it through $form->format_string. If it is not a CGI environment and $ENV{error_function} is set, call the specified function with $msg as the sole argument. Otherwise, this function simply dies with $msg.

If $maxrows is set and the number of rows is greater than $maxrows, this returns $maxrows. In the determination of rowcount, newline characters, "\n", are taken into account while spaces are not. =cut sub numtextrows { my ( $self, $str, $cols, $maxrows ) = @_; my $rows = 0; for ( split /\n/, $str ) { $rows += int( ( (length) - 2 ) / $cols ) + 1; } $maxrows = $rows unless defined $maxrows; return ( $rows > $maxrows ) ? $maxrows : $rows; } =item $form->dberror($msg); Outputs a message as in $form->error but with $DBI::errstr automatically appended to $msg. =cut sub dberror { my ( $self, $msg ) = @_; $self->error( "$msg\n" . $DBI::errstr ); } =item $form->isblank($name, $msg); Calls $form->error($msg) if the value of $form->{$name} matches /^\s*$/. =cut sub isblank { my ( $self, $name, $msg ) = @_; $self->error($msg) if $self->{$name} =~ /^\s*$/; } =item $form->header([$init, $headeradd]); Outputs HTML and HTTP headers and sets $form->{header} to indicate that headers have been output. If called with $form->{header} set or in a non-CGI environment, does not output anything. $init is ignored. $headeradd is data to be added to the portion of the output headers. $form->{stylesheet}, $form->{title}, $form->{titlebar}, and $form->{pre} all affect the output of this function. If the stylesheet indicated by $form->{stylesheet} exists, output a link tag to reference it. If $form->{title} is false, the title text is the value of $form->{titlebar}. If $form->{title} is true, the title text takes the form of "$form->{title} - $form->{titlebar}".

If $form->{sort} is unset, do nothing. If the value of $form->{sort} does not exist in @columns, returns the list formed by the value of $form->{sort} followed by the values of @columns. If the value of $form->{sort} is in @columns, return the list formed by @columns with the value of $form->{sort} moved to the head of the list. =cut sub sort_columns { my ( $self, @columns ) = @_; if ( $self->{sort} ) { $self->{sort} =~ s/^"*(.*?)"*$/$1/; if (@columns) { @columns = grep !/^$self->{sort}$/, @columns; if ($self->{sort} !~ /^\w*$/){ $self->{sort} = $self->{dbh}->quote_identifier($self->{sort}); } splice @columns, 0, 0, $self->{sort}; } } @columns; } =item $form->sort_order($columns[, $ordinal]); Returns a string that contains ordering details for the columns in SQL form. $columns is a reference to a list of columns, $ordinal is a reference to a hash that maps column names to ordinal positions. This function depends upon the values of $form->{direction}, $form->{sort}, and $form->{oldsort}. If $form->{direction} is false, it becomes 'ASC'. If $form->{direction} is true and $form->{sort} and $form->{oldsort} are equal, reverse the order specified by $form->{direction}. $form->{oldsort} is set to the same value as $form->{sort} The actual sorting of $columns happens as in $form->sort_columns(@$columns).
