355 A module modeled a bit after Rails' ActionView helpers. Several small
356 functions that create HTML tags from various kinds of data sources.
358 The C<id> attribute is usually calculated automatically. This can be
359 overridden by either specifying an C<id> attribute or by setting
364 =head2 LOW-LEVEL FUNCTIONS
368 =item C<html_tag $tag_name, $content_string, %attributes>
370 Creates an opening and closing HTML tag for C<$tag_name> and puts
371 C<$content_string> between the two. If C<$content_string> is undefined
372 or empty then only a E<lt>tag/E<gt> tag will be created. Attributes
373 are key/value pairs added to the opening tag.
375 C<$content_string> is not HTML escaped.
377 =item C<name_to_id $name>
379 Converts a name to a HTML id by replacing various characters.
381 =item C<stringify_attributes %items>
383 Creates a string from all elements in C<%items> suitable for usage as
384 HTML tag attributes. Keys and values are HTML escaped even though keys
385 must not contain non-ASCII characters for browsers to accept them.
387 =item C<restricted_html $html>
389 Returns HTML stripped of unknown tags. See L<SL::HTML::Restrict>.
393 =head2 HIGH-LEVEL FUNCTIONS
397 =item C<input_tag $name, $value, %attributes>
399 Creates a HTML 'input type=text' tag named C<$name> with the value
400 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
401 tag's C<id> defaults to C<name_to_id($name)>.
403 =item C<submit_tag $name, $value, %attributes>
405 Creates a HTML 'input type=submit class=submit' tag named C<$name> with the
406 value C<$value> and with arbitrary HTML attributes from C<%attributes>. The
407 tag's C<id> defaults to C<name_to_id($name)>.
409 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
410 be added via the C<onclick> handler asking the question given with
411 C<$attributes{confirm}>. The request is only submitted if the user
412 clicks the dialog's ok/yes button.
414 =item C<ajax_submit_tag $url, $form_selector, $text, %attributes>
416 Creates a HTML 'input type="button"' tag with a very specific onclick
417 handler that submits the form given by the jQuery selector
418 C<$form_selector> to the URL C<$url> (the actual JavaScript function
419 called for that is C<kivi.submit_ajax_form()> in
420 C<js/client_js.js>). The button's label will be C<$text>.
422 =item C<button_tag $onclick, $text, %attributes>
424 Creates a HTML 'input type="button"' tag with an onclick handler
425 C<$onclick> and a value of C<$text>. The button does not have a name
426 nor an ID by default.
428 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
429 be prepended to the C<$onclick> handler asking the question given with
430 C<$attributes{confirm}>. The request is only submitted if the user
431 clicks the dialog's "ok/yes" button.
433 =item C<man_days_tag $name, $object, %attributes>
435 Creates two HTML inputs: a text input for entering a number and a drop
436 down box for chosing the unit (either 'man days' or 'hours').
438 C<$object> must be a L<Rose::DB::Object> instance using the
439 L<SL::DB::Helper::AttrDuration> helper.
441 C<$name> is supposed to be the name of the underlying column,
442 e.g. C<time_estimation> for an instance of
443 C<SL::DB::RequirementSpecItem>. If C<$name> has the form
444 C<prefix.method> then the full C<$name> is used for the input's base
445 names while the methods called on C<$object> are only the suffix. This
446 makes it possible to write statements like e.g.
448 [% P.man_days_tag("requirement_spec_item.time_estimation", SELF.item) %]
450 The attribute C<size> can be used to set the text input's size. It
453 =item C<hidden_tag $name, $value, %attributes>
455 Creates a HTML 'input type=hidden' tag named C<$name> with the value
456 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
457 tag's C<id> defaults to C<name_to_id($name)>.
459 =item C<checkbox_tag $name, %attributes>
461 Creates a HTML 'input type=checkbox' tag named C<$name> with arbitrary
462 HTML attributes from C<%attributes>. The tag's C<id> defaults to
463 C<name_to_id($name)>. The tag's C<value> defaults to C<1>.
465 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
466 created with said C<label>. No attribute named C<label> is created in
469 If C<%attributes> contains a key C<checkall> then the value is taken as a
470 JQuery selector and clicking this checkbox will also toggle all checkboxes
471 matching the selector.
473 =item C<select_tag $name, \@collection, %attributes>
475 Creates an HTML 'select' tag named C<$name> with the contents of one
476 'E<lt>optionE<gt>' tag for each element in C<\@collection> and with arbitrary
477 HTML attributes from C<%attributes>. The value
478 to use and the title to display are extracted from the elements in
479 C<\@collection>. Each element can be one of four things:
483 =item 1. An array reference with at least two elements. The first element is
484 the value, the second element is its title. The third element is optional and and should contain a boolean.
485 If it is true, than the element will be used as default.
487 =item 2. A scalar. The scalar is both the value and the title.
489 =item 3. A hash reference. In this case C<%attributes> must contain
490 I<value_key>, I<title_key> and may contain I<default_key> keys that name the keys in the element to use
491 for the value, title and default respectively.
493 =item 4. A blessed reference. In this case C<%attributes> must contain
494 I<value_key>, I<title_key> and may contain I<default_key> keys that name functions called on the blessed
495 reference whose return values are used as the value, title and default
500 For cases 3 and 4 C<$attributes{value_key}> defaults to C<id>,
501 C<$attributes{title_key}> defaults to C<$attributes{value_key}> and
502 C<$attributes{default_key}> defaults to C<selected>. Note that
503 C<$attributes{default_key}> is set to C<undef> if
504 C<$attributes{default_value_key}> is used as well (see below).
506 In addition to pure keys/method you can also provide coderefs as I<value_sub>
507 and/or I<title_sub> and/or I<default_sub>. If present, these take precedence over keys or methods,
508 and are called with the element as first argument. It must return the value, title or default.
510 Lastly a joint coderef I<value_title_sub> may be provided, which in turn takes
511 precedence over the C<value_sub> and C<title_sub> subs. It will only be called once for each
512 element and must return a list of value and title.
514 If the option C<with_empty> is set then an empty element (value
515 C<undef>) will be used as the first element. The title to display for
516 this element can be set with the option C<empty_title> and defaults to
519 The tag's C<id> defaults to C<name_to_id($name)>.
521 The option C<default> can be quite a lot of things:
525 =item 1. A scalar value. This is the value of the entry that's
528 =item 2. A hash reference for C<multiple=1>. Whether or not an entry
529 is selected by default is looked up in this hash.
531 =item 3. An array reference containing scalar values. Same as 1., just
532 for the case of C<multiple=1>.
534 =item 4. If C<default_value_key> is given: an array reference of hash
535 references. For each hash reference the value belonging to the key
536 C<default_value_key> is treated as one value to select by
537 default. Constructs a hash that's treated like 3.
539 =item 5. If C<default_value_key> is given: an array reference of
540 blessed objects. For each object the value returne from calling the
541 function named C<default_value_key> on the object is treated as one
542 value to select by default. Constructs a hash that's treated like 3.
546 5. also applies to single RDBO instances (due to 'wantarray'
547 shenanigans assigning RDBO's relationships to a hash key will result
548 in a single RDBO object being assigned instead of an array reference
549 containing that single RDBO object).
551 If the option C<with_optgroups> is set then this function expects
552 C<\@collection> to be one level deeper. The upper-most level is
553 translated into an HTML C<optgroup> tag. So the structure becomes:
557 =item 1. Array of array references. Each element in the
558 C<\@collection> is converted into an optgroup.
560 =item 2. The optgroup's C<label> attribute will be set to the
561 first element in the array element. The second array element is then
562 converted to a list of C<option> tags as described above.
566 Example for use of optgroups:
568 # First in a controller:
570 [ t8("First optgroup with three items"),
571 [ { id => 42, name => "item one" },
572 { id => 54, name => "second item" },
573 { id => 23, name => "and the third one" },
575 [ t8("Another optgroup, with a lot of items from Rose"),
576 SL::DB::Manager::Customer->get_all_sorted ],
579 # Later in the template:
580 [% L.select_tag('the_selection', COLLECTION, with_optgroups=1, title_key='name') %]
