392 A module modeled a bit after Rails' ActionView helpers. Several small
393 functions that create HTML tags from various kinds of data sources.
395 The C<id> attribute is usually calculated automatically. This can be
396 overridden by either specifying an C<id> attribute or by setting
401 =head2 LOW-LEVEL FUNCTIONS
405 =item C<html_tag $tag_name, $content_string, %attributes>
407 Creates an opening and closing HTML tag for C<$tag_name> and puts
408 C<$content_string> between the two. If C<$content_string> is undefined
409 or empty then only a E<lt>tag/E<gt> tag will be created. Attributes
410 are key/value pairs added to the opening tag.
412 C<$content_string> is not HTML escaped.
414 =item C<name_to_id $name>
416 Converts a name to a HTML id by replacing various characters.
418 =item C<stringify_attributes %items>
420 Creates a string from all elements in C<%items> suitable for usage as
421 HTML tag attributes. Keys and values are HTML escaped even though keys
422 must not contain non-ASCII characters for browsers to accept them.
424 =item C<restricted_html $html>
426 Returns HTML stripped of unknown tags. See L<SL::HTML::Restrict>.
430 =head2 HIGH-LEVEL FUNCTIONS
434 =item C<input_tag $name, $value, %attributes>
436 Creates a HTML 'input type=text' tag named C<$name> with the value
437 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
438 tag's C<id> defaults to C<name_to_id($name)>.
440 =item C<submit_tag $name, $value, %attributes>
442 Creates a HTML 'input type=submit class=submit' tag named C<$name> with the
443 value C<$value> and with arbitrary HTML attributes from C<%attributes>. The
444 tag's C<id> defaults to C<name_to_id($name)>.
446 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
447 be added via the C<onclick> handler asking the question given with
448 C<$attributes{confirm}>. The request is only submitted if the user
449 clicks the dialog's ok/yes button.
451 =item C<ajax_submit_tag $url, $form_selector, $text, %attributes>
453 Creates a HTML 'input type="button"' tag with a very specific onclick
454 handler that submits the form given by the jQuery selector
455 C<$form_selector> to the URL C<$url> (the actual JavaScript function
456 called for that is C<kivi.submit_ajax_form()> in
457 C<js/client_js.js>). The button's label will be C<$text>.
459 =item C<button_tag $onclick, $text, %attributes>
461 Creates a HTML 'input type="button"' tag with an onclick handler
462 C<$onclick> and a value of C<$text>. The button does not have a name
463 nor an ID by default.
465 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
466 be prepended to the C<$onclick> handler asking the question given with
467 C<$attributes{confirm}>. The request is only submitted if the user
468 clicks the dialog's "ok/yes" button.
470 =item C<man_days_tag $name, $object, %attributes>
472 Creates two HTML inputs: a text input for entering a number and a drop
473 down box for chosing the unit (either 'man days' or 'hours').
475 C<$object> must be a L<Rose::DB::Object> instance using the
476 L<SL::DB::Helper::AttrDuration> helper.
478 C<$name> is supposed to be the name of the underlying column,
479 e.g. C<time_estimation> for an instance of
480 C<SL::DB::RequirementSpecItem>. If C<$name> has the form
481 C<prefix.method> then the full C<$name> is used for the input's base
482 names while the methods called on C<$object> are only the suffix. This
483 makes it possible to write statements like e.g.
485 [% P.man_days_tag("requirement_spec_item.time_estimation", SELF.item) %]
487 The attribute C<size> can be used to set the text input's size. It
490 =item C<hidden_tag $name, $value, %attributes>
492 Creates a HTML 'input type=hidden' tag named C<$name> with the value
493 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
494 tag's C<id> defaults to C<name_to_id($name)>.
496 =item C<checkbox_tag $name, %attributes>
498 Creates a HTML 'input type=checkbox' tag named C<$name> with arbitrary
499 HTML attributes from C<%attributes>. The tag's C<id> defaults to
500 C<name_to_id($name)>. The tag's C<value> defaults to C<1>.
502 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
503 created with said C<label>. No attribute named C<label> is created in
506 If C<%attributes> contains a key C<checkall> then the value is taken as a
507 JQuery selector and clicking this checkbox will also toggle all checkboxes
508 matching the selector.
510 =item C<select_tag $name, \@collection, %attributes>
512 Creates an HTML 'select' tag named C<$name> with the contents of one
513 'E<lt>optionE<gt>' tag for each element in C<\@collection> and with arbitrary
514 HTML attributes from C<%attributes>. The value
515 to use and the title to display are extracted from the elements in
516 C<\@collection>. Each element can be one of four things:
520 =item 1. An array reference with at least two elements. The first element is
521 the value, the second element is its title. The third element is optional and and should contain a boolean.
522 If it is true, than the element will be used as default.
524 =item 2. A scalar. The scalar is both the value and the title.
526 =item 3. A hash reference. In this case C<%attributes> must contain
527 I<value_key>, I<title_key> and may contain I<default_key> keys that name the keys in the element to use
528 for the value, title and default respectively.
530 =item 4. A blessed reference. In this case C<%attributes> must contain
531 I<value_key>, I<title_key> and may contain I<default_key> keys that name functions called on the blessed
532 reference whose return values are used as the value, title and default
537 For cases 3 and 4 C<$attributes{value_key}> defaults to C<id>,
538 C<$attributes{title_key}> defaults to C<$attributes{value_key}> and
539 C<$attributes{default_key}> defaults to C<selected>. Note that
540 C<$attributes{default_key}> is set to C<undef> if
541 C<$attributes{default_value_key}> is used as well (see below).
543 In addition to pure keys/method you can also provide coderefs as I<value_sub>
544 and/or I<title_sub> and/or I<default_sub>. If present, these take precedence over keys or methods,
545 and are called with the element as first argument. It must return the value, title or default.
547 Lastly a joint coderef I<value_title_sub> may be provided, which in turn takes
548 precedence over the C<value_sub> and C<title_sub> subs. It will only be called once for each
549 element and must return a list of value and title.
551 If the option C<with_empty> is set then an empty element (value
552 C<undef>) will be used as the first element. The title to display for
553 this element can be set with the option C<empty_title> and defaults to
556 The tag's C<id> defaults to C<name_to_id($name)>.
558 The option C<default> can be quite a lot of things:
562 =item 1. A scalar value. This is the value of the entry that's
565 =item 2. A hash reference for C<multiple=1>. Whether or not an entry
566 is selected by default is looked up in this hash.
568 =item 3. An array reference containing scalar values. Same as 1., just
569 for the case of C<multiple=1>.
571 =item 4. If C<default_value_key> is given: an array reference of hash
572 references. For each hash reference the value belonging to the key
573 C<default_value_key> is treated as one value to select by
574 default. Constructs a hash that's treated like 3.
576 =item 5. If C<default_value_key> is given: an array reference of
577 blessed objects. For each object the value returne from calling the
578 function named C<default_value_key> on the object is treated as one
579 value to select by default. Constructs a hash that's treated like 3.
583 5. also applies to single RDBO instances (due to 'wantarray'
584 shenanigans assigning RDBO's relationships to a hash key will result
585 in a single RDBO object being assigned instead of an array reference
586 containing that single RDBO object).
588 If the option C<with_optgroups> is set then this function expects
589 C<\@collection> to be one level deeper. The upper-most level is
590 translated into an HTML C<optgroup> tag. So the structure becomes:
594 =item 1. Array of array references. Each element in the
595 C<\@collection> is converted into an optgroup.
597 =item 2. The optgroup's C<label> attribute will be set to the
598 first element in the array element. The second array element is then
599 converted to a list of C<option> tags as described above.
603 Example for use of optgroups:
605 # First in a controller:
607 [ t8("First optgroup with three items"),
608 [ { id => 42, name => "item one" },
609 { id => 54, name => "second item" },
610 { id => 23, name => "and the third one" },
612 [ t8("Another optgroup, with a lot of items from Rose"),
613 SL::DB::Manager::Customer->get_all_sorted ],
616 # Later in the template:
617 [% L.select_tag('the_selection', COLLECTION, with_optgroups=1, title_key='name') %]
