Template::Magic::HTML(User Contributed Perl DocumentatTemplate::Magic::HTML(3) NAME Template::Magic::HTML - HTML handlers for Template::Magic used in a HTML environment VERSION 1.39 Included in Template-Magic 1.39 distribution. The latest versions changes are reported in the Changes file in this distribution. SYNOPSIS $tm = new Template::Magic::HTML ; # that means $tm = new Template::Magic markers => 'HTML' , value_handlers => 'HTML' ; # that explicitly means $tm = new Template::Magic markers => [ qw( <!--{ / }--> ) ], value_handlers => [ qw( SCALAR REF CODE TableTiler ARRAY HASH FillInForm ) ] ; DESCRIPTION Template::Magic::HTML is a collection of handlers for Template::Magic useful when used in a HTML environment. It adds a couple of magic HTML specific value handlers to Template::Magic default value handlers. Just create and use the object as usual, to have a trasparent interface to HTML::TableTiler and HTML::FillInForm too. Other interesting readings about how to use this collection are in: o Template::Magic (general documentation about the Template-Magic system) o Template::Magic::Zone HTML VALUE HANDLERS HTML This is the shortcut for the complete HTML collection of handlers that defines the following value handlers: SCALAR REF CODE TableTiler ARRAY HASH FillInForm See "standard value handlers" in Template::Magic for details about SCALAR REF CODE ARRAY and HASH handlers. TableTiler Condition a bidimensional array value Action magic generation of HTML table. No need to create and use a HTML::TableTiler object: this handler will manage it magically. Description The bidimensional array: $matrix_generating_a_table = [ [1..3], [4..6], [7..9] ]; The template could be as simple as a simple label with the same identifier of the bidimensional array: <p>paragraph text</p> <!--{matrix_generating_a_table}--> <p>other paragraph</p> so the output will be a generic table including the array data: <p>paragraph text</p> <table> <tr> <td>1</td> <td>2</td> <td>3</td> </tr> <tr> <td>4</td> <td>5</td> <td>6</td> </tr> <tr> <td>7</td> <td>8</td> <td>9</td> </tr> </table> <p>paragraph text</p> or the template could be a complete table Tile included in a block with the same identifier of the bidimensional array, and with the optional ROW and COL TableTiler modes, passed as label attributes: <p>paragraph text</p> <!--{matrix_generating_a_table H_TILE V_TILE}--> <table border="1" cellspacing="2" cellpadding="2"> <tr> <td><b><i>?</i></b></td> <td>?</td> </tr> <tr> <td>?</td> <td><b><i>?</i></b></td> </tr> </table> <!--{/matrix_generating_a_table}--> <p>other paragraph</p> so the output will be a complete tiled table including the array data: <p>paragraph text</p> <table border="1" cellspacing="2" cellpadding="2"> <tr> <td><b><i>1</i></b></td> <td>2</td> <td><b><i>3</i></b></td> </tr> <tr> <td>4</td> <td><b><i>5</i></b></td> <td>6</td> </tr> <tr> <td><b><i>7</i></b></td> <td>8</td> <td><b><i>9</i></b></td> </tr> </table> <p>paragraph text</p> See HTML::TableTiler for details about this module. Note: if your template don't need this specific handler you can avoid its loading by explicitly omitting it: $tm = new Template::Magic::HTML value_handlers => [ qw( SCALAR REF CODE ARRAY HASH FillInForm ) ] ; Warning: since this handler checks for a bidimensional ARRAY, it must be checked BEFORE the ARRAY value handler in order to work. FillInForm Condition a CGI query object value (or by a blessed object that has a param() method) Action magic fill in of a HTML form with the parameter in the CGI object Description The CGI object in your code: $my_query = new CGI; If you want to fill a form with the param in the $my_query, just transform the form into a block giving it the same identifier. <!--{my_query}--> <form action="my.cgi"> ... </form> <!--{/my_query}--> One useful application of this handler is when a user submits an HTML form without filling out a required field. FillInForm handler will magically redisplay the form with all the form elements (input, textarea and select tags) filled with the submitted info ($my_query), without any other statement in your code. (No need to create and use a HTML::FillInForm object: this handler will manage it magically). You can use this handler to fill the form with default values too, To do this, just create a new query object and fill it with the default param that you want in the form: $query = new CGI; $query->param( name => 'John', surname => 'Smith', ...); You can pass an array of ignore_fields (see HTML::FillInForm for details) by using the attributes like this: <!--{my_query ignore_fields => [ 'prev', 'next'] }--> <form action="my.cgi"> ... </form> <!--{/my_query}--> See HTML::FillInForm for details about this module. Note: if your template don't need this specific handler you can avoid its loading by explicitly omitting it: $tm = new Template::Magic::HTML value_handlers => [ qw( SCALAR REF CODE TableTiler ARRAY HASH ) ] ; SEE ALSO o Template::Magic o Template::Magic::Zone o HTML::TableTiler o HTML::FillInForm SUPPORT Support for all the modules of the Template Magic System is via the mailing list. The list is used for general support on the use of the Template::Magic, announcements, bug reports, patches, suggestions for improvements or new features. The API to the Magic Template System is stable, but if you use it in a production environment, it's probably a good idea to keep a watch on the list.
