NAME
HTML::FillInForm::Lite - Lightweight FillInForm module in Pure Perl
VERSION
The document describes HTML::FillInForm::Lite version 1.15
SYNOPSIS
use HTML::FillInForm::Lite;
use CGI;
my $q = CGI->new();
my $h = HTML::FillInForm::Lite->new();
$output = $h->fill(\$html, $q);
$output = $h->fill(\@html, \%data);
$output = $h->fill(\*HTML, \&my_param);
$output = $h->fill('t.html', [$q, \%default]);
# or as a class method with options
$output = HTML::FillInForm::Lite->fill(\$html, $q,
fill_password => 0, # it is default
ignore_fields => ['foo', 'bar'],
target => $form_id,
);
# Moreover, it accepts any object as form data
# (these classes come form Class::DBI's SYNOPSIS)
my $artist = Music::Artist->insert({ id => 1, name => 'U2' });
$output = $h->fill(\$html, $artist);
my $cd = Music::CD->retrieve(1);
$output = $h->fill(\$html, $cd);
# simple function interface
use HTML::FillInForm::Lite qw(fillinform);
# the same as HTML::FillInForm::Lite->fill(...)
$output = fillinform(\$html, $q);
DESCRIPTION
This module fills in HTML forms with Perl data, which re-implements HTML::FillInForm
using regexp-based parser, not using HTML::Parser
.
The difference in the parsers makes HTML::FillInForm::Lite
about 2 times faster than HTML::FillInForm
.
FUNCTIONS
fillinform(source, form_data)
Simple interface to the fill()
method, accepting only a string. If you pass a single argument to this function, it is interpreted as form_data, and returns a function that accepts source.
my $fillinform = fillinform($query);
$fillinform->($html); # the same as fillinform($html, $query)
This function is exportable.
METHODS
new(options...)
Creates HTML::FillInForm::Lite
processor with options.
There are several options. All the options are disabled when undef
is supplied.
Acceptable options are as follows:
- fill_password => bool
-
To enable passwords to be filled in, set the option true.
Note that the effect of the option is the same as that of
HTML::FillInForm
, but by defaultHTML::FillInForm::Lite
ignores password fields. - ignore_fields => array_ref_of_fields
-
To ignore some fields from filling.
- target => form_id
-
To fill in just the form identified by form_id.
- escape => bool | ref
-
If true is provided (or by default), values filled in text fields will be HTML-escaped, e.g.
<tag>
to be<tag>
.If the values are already HTML-escaped, set the option false.
You can supply a subroutine reference to escape the values.
Note that it is not implemented in
HTML::FillInForm
. - decode_entity => bool | ref
-
If true is provided , HTML entities in state fields (namely,
radio
,checkbox
andselect
) will be decoded, but normally it is not needed.You can also supply a subroutine reference to decode HTML entities.
Note that
HTML::FillInForm
always decodes HTML entities in state fields, but not supports this option. - layer => :iolayer
-
To read a file with :iolayer. It is used when a file name is supplied as source.
For example:
# To read a file encoded in UTF-8 $fif = HTML::FillInForm::Lite->new(layer => ':utf8'); $output = $fif->fill($utf8_file, $fdat); # To read a file encoded in EUC-JP $fif = HTML::FillInForm::Lite->new(layer => ':encoding(euc-jp)'); $output = $fif->fill($eucjp_file, $fdat);
Note that it is not implemented in
HTML::FillInForm
.
fill(source, form_data [, options...])
Fills in source with form_data. If source or form_data is not supplied, it will cause die
.
options are the same as new()
's.
You can use this method as a both class or instance method, but you make multiple calls to fill()
with the same options, it is a little faster to call new()
and store the instance.
source may be a scalar reference, an array reference of strings, or a file name.
form_data may be a hash reference, an object with param()
method, an object with accessors, a code reference, or an array reference of those above mentioned.
If form_data is based on procedures (i.e. not a hash reference), the procedures will be called in the list context. Therefore, to leave some fields untouched, it must return a null list ()
, not undef
.
DEPENDENCIES
Perl 5.8.1 or later.
NOTES
Compatibility with HTML::FillInForm
This module implements only the new syntax of HTML::FillInForm
version 2. However, HTML::FillInForm::Lite::Compat
provides an interface compatible with HTML::FillInForm
.
Compatibility with legacy HTML
This module is designed to process XHTML 1.x.
And it also supporting a good part of HTML 4.x , but there are some limitations. First, it doesn't understand HTML-attributes that the name is omitted.
For example:
<INPUT TYPE=checkbox NAME=foo CHECKED> -- NG.
<INPUT TYPE=checkbox NAME=foo CHECKED=checked> - OK, but obsolete.
<input type="checkbox" name="foo" checked="checked" /> - OK, valid XHTML
Then, it always treats the values of attributes case-sensitively. In the example above, the value of type
must be lower-case.
Moreover, it doesn't recognize omitted closing tags, like:
<select name="foo">
<option>bar
<option>baz
</select>
When you can't get what you want, try to give your source to a HTML lint.
Comment handling
This module processes all the processable, not knowing comments nor something that shouldn't be processed.
It may cause problems. Suppose there is a code like:
<script> document.write("<input name='foo' />") </script>
HTML::FillInForm::Lite
will break the code:
<script> document.write("<input name='foo' value="bar" />") </script>
To avoid such problems, you can use the ignore_fields
option.
