=head1 NAME
FS::template_image - Object methods for template_image records
=head1 SYNOPSIS
use FS::template_image;
$record = new FS::template_image {
'name' => 'logo',
'agentnum' => $agentnum,
'base64' => encode_base64($rawdata),
'mime_type' => 'image/jpg',
};
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::template_image object represents an uploaded image for insertion into templates.
FS::template_image inherits from FS::Record. The following fields are currently supported:
=over 4
=item imgnum - primary key
=item name - unique name, for selecting/editing images
=item agentnum - image agent
=item mime-type - image mime-type
=item base64 - base64-encoded raw contents of image file
=back
=head1 METHODS
=over 4
=item new HASHREF
Creates a new object. To add the object to the database, see L<"insert">.
Note that this stores the hash reference, not a distinct copy of the hash it
points to. You can ask the object for a copy with the I<hash> method.
=cut
# the new method can be inherited from FS::Record, if a table method is defined
sub table { 'template_image'; }
=item insert
Adds this record to the database. If there is an error, returns the error,
otherwise returns false.
=cut
# the insert method can be inherited from FS::Record
=item delete
Delete this record from the database.
=cut
# the delete method can be inherited from FS::Record
=item replace OLD_RECORD
Replaces the OLD_RECORD with this one in the database. If there is an error,
returns the error, otherwise returns false.
=cut
# the replace method can be inherited from FS::Record
=item check
Checks all fields to make sure this is a valid example. If there is
an error, returns the error, otherwise returns false. Called by the insert
and replace methods.
=cut
# the check method should currently be supplied - FS::Record contains some
# data checking routines
sub check {
my $self = shift;
my $error =
$self->ut_numbern('imgnum','agentnum')
|| $self->ut_text('name','mime-type')
|| $self->ut_anything('base64')
;
return $error if $error;
$self->SUPER::check;
}
=item src
Returns a data url for this image, incorporating mime_type & base64
=cut
sub src {
my $self = shift;
'data:'
. $self->mime_type
. ';base64,'
. $self->base64;
}
=item html
Returns html for a basic img tag for this image (no attributes)
=cut
sub html {
my $self = shift;
'<IMG SRC="'
. $self->src
. '">';
}
=item process_image_delete
Process for deleting an image. Run as a job using L<FS::queue>.
=cut
sub process_image_delete {
my $job = shift;
my $param = shift;
my $template_image = qsearchs('template_image',{ 'imgnum' => $param->{'imgnum'} })
or die "Could not load template_image";
my $error = $template_image->delete;
die $error if $error;
'';
}
=item process_image_upload
Process for uploading an image. Run as a job using L<FS::queue>.
=cut
sub process_image_upload {
my $job = shift;
my $param = shift;
my $files = $param->{'uploaded_files'}
or die "No files provided.\n";
my (%files) = map { /^(\w+):([\.\w]+)$/ ? ($1,$2):() } split /,/, $files;
my $dir = '%%%FREESIDE_CACHE%%%/cache.'. $FS::UID::datasrc. '/';
my $file = $dir. $files{'file'};
my $type;
if ( $file =~ /\.(\w+)$/i ) {
my $ext = lc($1);
die "Unrecognized file extension $ext"
unless $ext_to_type{$ext};
$type = $ext_to_type{$ext};
} else {
die "Cannot upload image file without extension"
}
my $template_image = new FS::template_image {
'name' => $param->{'name'},
'mime_type' => $type,
'agentnum' => $param->{'agentnum'},
'base64' => encode_base64( slurp($file, binmode => ':raw'), '' ),
};
my $error = $template_image->insert();
die $error if $error;
unlink $file;
