360 A module modeled a bit after Rails' ActionView helpers. Several small
361 functions that create HTML tags from various kinds of data sources.
363 The C<id> attribute is usually calculated automatically. This can be
364 overridden by either specifying an C<id> attribute or by setting
369 =head2 LOW-LEVEL FUNCTIONS
373 =item C<html_tag $tag_name, $content_string, %attributes>
375 Creates an opening and closing HTML tag for C<$tag_name> and puts
376 C<$content_string> between the two. If C<$content_string> is undefined
377 or empty then only a E<lt>tag/E<gt> tag will be created. Attributes
378 are key/value pairs added to the opening tag.
380 C<$content_string> is not HTML escaped.
382 =item C<name_to_id $name>
384 Converts a name to a HTML id by replacing various characters.
386 =item C<stringify_attributes %items>
388 Creates a string from all elements in C<%items> suitable for usage as
389 HTML tag attributes. Keys and values are HTML escaped even though keys
390 must not contain non-ASCII characters for browsers to accept them.
392 =item C<restricted_html $html>
394 Returns HTML stripped of unknown tags. See L<SL::HTML::Restrict>.
398 =head2 HIGH-LEVEL FUNCTIONS
402 =item C<input_tag $name, $value, %attributes>
404 Creates a HTML 'input type=text' tag named C<$name> with the value
405 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
406 tag's C<id> defaults to C<name_to_id($name)>.
408 =item C<submit_tag $name, $value, %attributes>
410 Creates a HTML 'input type=submit class=submit' tag named C<$name> with the
411 value C<$value> and with arbitrary HTML attributes from C<%attributes>. The
412 tag's C<id> defaults to C<name_to_id($name)>.
414 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
415 be added via the C<onclick> handler asking the question given with
416 C<$attributes{confirm}>. The request is only submitted if the user
417 clicks the dialog's ok/yes button.
419 =item C<ajax_submit_tag $url, $form_selector, $text, %attributes>
421 Creates a HTML 'input type="button"' tag with a very specific onclick
422 handler that submits the form given by the jQuery selector
423 C<$form_selector> to the URL C<$url> (the actual JavaScript function
424 called for that is C<kivi.submit_ajax_form()> in
425 C<js/client_js.js>). The button's label will be C<$text>.
427 =item C<button_tag $onclick, $text, %attributes>
429 Creates a HTML 'input type="button"' tag with an onclick handler
430 C<$onclick> and a value of C<$text>. The button does not have a name
431 nor an ID by default.
433 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
434 be prepended to the C<$onclick> handler asking the question given with
435 C<$attributes{confirm}>. The request is only submitted if the user
436 clicks the dialog's "ok/yes" button.
438 =item C<man_days_tag $name, $object, %attributes>
440 Creates two HTML inputs: a text input for entering a number and a drop
441 down box for chosing the unit (either 'man days' or 'hours').
443 C<$object> must be a L<Rose::DB::Object> instance using the
444 L<SL::DB::Helper::AttrDuration> helper.
446 C<$name> is supposed to be the name of the underlying column,
447 e.g. C<time_estimation> for an instance of
448 C<SL::DB::RequirementSpecItem>. If C<$name> has the form
449 C<prefix.method> then the full C<$name> is used for the input's base
450 names while the methods called on C<$object> are only the suffix. This
451 makes it possible to write statements like e.g.
453 [% P.man_days_tag("requirement_spec_item.time_estimation", SELF.item) %]
455 The attribute C<size> can be used to set the text input's size. It
458 =item C<hidden_tag $name, $value, %attributes>
460 Creates a HTML 'input type=hidden' tag named C<$name> with the value
461 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
462 tag's C<id> defaults to C<name_to_id($name)>.
464 =item C<checkbox_tag $name, %attributes>
466 Creates a HTML 'input type=checkbox' tag named C<$name> with arbitrary
467 HTML attributes from C<%attributes>. The tag's C<id> defaults to
468 C<name_to_id($name)>. The tag's C<value> defaults to C<1>.
470 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
471 created with said C<label>. No attribute named C<label> is created in
474 If C<%attributes> contains a key C<checkall> then the value is taken as a
475 JQuery selector and clicking this checkbox will also toggle all checkboxes
476 matching the selector.
478 =item C<select_tag $name, \@collection, %attributes>
480 Creates an HTML 'select' tag named C<$name> with the contents of one
481 'E<lt>optionE<gt>' tag for each element in C<\@collection> and with arbitrary
482 HTML attributes from C<%attributes>. The value
483 to use and the title to display are extracted from the elements in
484 C<\@collection>. Each element can be one of four things:
488 =item 1. An array reference with at least two elements. The first element is
489 the value, the second element is its title. The third element is optional and and should contain a boolean.
490 If it is true, than the element will be used as default.
492 =item 2. A scalar. The scalar is both the value and the title.
494 =item 3. A hash reference. In this case C<%attributes> must contain
495 I<value_key>, I<title_key> and may contain I<default_key> keys that name the keys in the element to use
496 for the value, title and default respectively.
498 =item 4. A blessed reference. In this case C<%attributes> must contain
499 I<value_key>, I<title_key> and may contain I<default_key> keys that name functions called on the blessed
500 reference whose return values are used as the value, title and default
505 For cases 3 and 4 C<$attributes{value_key}> defaults to C<id>,
506 C<$attributes{title_key}> defaults to C<$attributes{value_key}> and
507 C<$attributes{default_key}> defaults to C<selected>. Note that
508 C<$attributes{default_key}> is set to C<undef> if
509 C<$attributes{default_value_key}> is used as well (see below).
511 In addition to pure keys/method you can also provide coderefs as I<value_sub>
512 and/or I<title_sub> and/or I<default_sub>. If present, these take precedence over keys or methods,
513 and are called with the element as first argument. It must return the value, title or default.
515 Lastly a joint coderef I<value_title_sub> may be provided, which in turn takes
516 precedence over the C<value_sub> and C<title_sub> subs. It will only be called once for each
517 element and must return a list of value and title.
519 If the option C<with_empty> is set then an empty element (value
520 C<undef>) will be used as the first element. The title to display for
521 this element can be set with the option C<empty_title> and defaults to
524 The tag's C<id> defaults to C<name_to_id($name)>.
526 The option C<default> can be quite a lot of things:
530 =item 1. A scalar value. This is the value of the entry that's
533 =item 2. A hash reference for C<multiple=1>. Whether or not an entry
534 is selected by default is looked up in this hash.
536 =item 3. An array reference containing scalar values. Same as 1., just
537 for the case of C<multiple=1>.
539 =item 4. If C<default_value_key> is given: an array reference of hash
540 references. For each hash reference the value belonging to the key
541 C<default_value_key> is treated as one value to select by
542 default. Constructs a hash that's treated like 3.
544 =item 5. If C<default_value_key> is given: an array reference of
545 blessed objects. For each object the value returne from calling the
546 function named C<default_value_key> on the object is treated as one
547 value to select by default. Constructs a hash that's treated like 3.
551 5. also applies to single RDBO instances (due to 'wantarray'
552 shenanigans assigning RDBO's relationships to a hash key will result
553 in a single RDBO object being assigned instead of an array reference
554 containing that single RDBO object).
556 If the option C<with_optgroups> is set then this function expects
557 C<\@collection> to be one level deeper. The upper-most level is
558 translated into an HTML C<optgroup> tag. So the structure becomes:
562 =item 1. Array of array references. Each element in the
563 C<\@collection> is converted into an optgroup.
565 =item 2. The optgroup's C<label> attribute will be set to the
566 first element in the array element. The second array element is then
567 converted to a list of C<option> tags as described above.
571 Example for use of optgroups:
573 # First in a controller:
575 [ t8("First optgroup with three items"),
576 [ { id => 42, name => "item one" },
577 { id => 54, name => "second item" },
578 { id => 23, name => "and the third one" },
580 [ t8("Another optgroup, with a lot of items from Rose"),
581 SL::DB::Manager::Customer->get_all_sorted ],
584 # Later in the template:
585 [% L.select_tag('the_selection', COLLECTION, with_optgroups=1, title_key='name') %]
