399 A module modeled a bit after Rails' ActionView helpers. Several small
400 functions that create HTML tags from various kinds of data sources.
402 The C<id> attribute is usually calculated automatically. This can be
403 overridden by either specifying an C<id> attribute or by setting
408 =head2 LOW-LEVEL FUNCTIONS
412 =item C<html_tag $tag_name, $content_string, %attributes>
414 Creates an opening and closing HTML tag for C<$tag_name> and puts
415 C<$content_string> between the two. If C<$content_string> is undefined
416 or empty then only a E<lt>tag/E<gt> tag will be created. Attributes
417 are key/value pairs added to the opening tag.
419 C<$content_string> is not HTML escaped.
421 =item C<name_to_id $name>
423 Converts a name to a HTML id by replacing various characters.
425 =item C<stringify_attributes %items>
427 Creates a string from all elements in C<%items> suitable for usage as
428 HTML tag attributes. Keys and values are HTML escaped even though keys
429 must not contain non-ASCII characters for browsers to accept them.
431 =item C<restricted_html $html>
433 Returns HTML stripped of unknown tags. See L<SL::HTML::Restrict>.
437 =head2 HIGH-LEVEL FUNCTIONS
441 =item C<input_tag $name, $value, %attributes>
443 Creates a HTML 'input type=text' tag named C<$name> with the value
444 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
445 tag's C<id> defaults to C<name_to_id($name)>.
447 =item C<submit_tag $name, $value, %attributes>
449 Creates a HTML 'input type=submit class=submit' tag named C<$name> with the
450 value C<$value> and with arbitrary HTML attributes from C<%attributes>. The
451 tag's C<id> defaults to C<name_to_id($name)>.
453 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
454 be added via the C<onclick> handler asking the question given with
455 C<$attributes{confirm}>. The request is only submitted if the user
456 clicks the dialog's ok/yes button.
458 =item C<ajax_submit_tag $url, $form_selector, $text, %attributes>
460 Creates a HTML 'input type="button"' tag with a very specific onclick
461 handler that submits the form given by the jQuery selector
462 C<$form_selector> to the URL C<$url> (the actual JavaScript function
463 called for that is C<kivi.submit_ajax_form()> in
464 C<js/client_js.js>). The button's label will be C<$text>.
466 =item C<button_tag $onclick, $text, %attributes>
468 Creates a HTML 'input type="button"' tag with an onclick handler
469 C<$onclick> and a value of C<$text>. The button does not have a name
470 nor an ID by default.
472 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
473 be prepended to the C<$onclick> handler asking the question given with
474 C<$attributes{confirm}>. The request is only submitted if the user
475 clicks the dialog's "ok/yes" button.
477 =item C<man_days_tag $name, $object, %attributes>
479 Creates two HTML inputs: a text input for entering a number and a drop
480 down box for chosing the unit (either 'man days' or 'hours').
482 C<$object> must be a L<Rose::DB::Object> instance using the
483 L<SL::DB::Helper::AttrDuration> helper.
485 C<$name> is supposed to be the name of the underlying column,
486 e.g. C<time_estimation> for an instance of
487 C<SL::DB::RequirementSpecItem>. If C<$name> has the form
488 C<prefix.method> then the full C<$name> is used for the input's base
489 names while the methods called on C<$object> are only the suffix. This
490 makes it possible to write statements like e.g.
492 [% P.man_days_tag("requirement_spec_item.time_estimation", SELF.item) %]
494 The attribute C<size> can be used to set the text input's size. It
497 =item C<hidden_tag $name, $value, %attributes>
499 Creates a HTML 'input type=hidden' tag named C<$name> with the value
500 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
501 tag's C<id> defaults to C<name_to_id($name)>.
503 =item C<checkbox_tag $name, %attributes>
505 Creates a HTML 'input type=checkbox' tag named C<$name> with arbitrary
506 HTML attributes from C<%attributes>. The tag's C<id> defaults to
507 C<name_to_id($name)>. The tag's C<value> defaults to C<1>.
509 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
510 created with said C<label>. No attribute named C<label> is created in
513 If C<%attributes> contains a key C<checkall> then the value is taken as a
514 JQuery selector and clicking this checkbox will also toggle all checkboxes
515 matching the selector.
517 =item C<select_tag $name, \@collection, %attributes>
519 Creates an HTML 'select' tag named C<$name> with the contents of one
520 'E<lt>optionE<gt>' tag for each element in C<\@collection> and with arbitrary
521 HTML attributes from C<%attributes>. The value
522 to use and the title to display are extracted from the elements in
523 C<\@collection>. Each element can be one of four things:
527 =item 1. An array reference with at least two elements. The first element is
528 the value, the second element is its title. The third element is optional and and should contain a boolean.
529 If it is true, than the element will be used as default.
531 =item 2. A scalar. The scalar is both the value and the title.
533 =item 3. A hash reference. In this case C<%attributes> must contain
534 I<value_key>, I<title_key> and may contain I<default_key> keys that name the keys in the element to use
535 for the value, title and default respectively.
537 =item 4. A blessed reference. In this case C<%attributes> must contain
538 I<value_key>, I<title_key> and may contain I<default_key> keys that name functions called on the blessed
539 reference whose return values are used as the value, title and default
544 For cases 3 and 4 C<$attributes{value_key}> defaults to C<id>,
545 C<$attributes{title_key}> defaults to C<$attributes{value_key}> and
546 C<$attributes{default_key}> defaults to C<selected>. Note that
547 C<$attributes{default_key}> is set to C<undef> if
548 C<$attributes{default_value_key}> is used as well (see below).
550 In addition to pure keys/method you can also provide coderefs as I<value_sub>
551 and/or I<title_sub> and/or I<default_sub>. If present, these take precedence over keys or methods,
552 and are called with the element as first argument. It must return the value, title or default.
554 Lastly a joint coderef I<value_title_sub> may be provided, which in turn takes
555 precedence over the C<value_sub> and C<title_sub> subs. It will only be called once for each
556 element and must return a list of value and title.
558 If the option C<with_empty> is set then an empty element (value
559 C<undef>) will be used as the first element. The title to display for
560 this element can be set with the option C<empty_title> and defaults to
563 The tag's C<id> defaults to C<name_to_id($name)>.
565 The option C<default> can be quite a lot of things:
569 =item 1. A scalar value. This is the value of the entry that's
572 =item 2. A hash reference for C<multiple=1>. Whether or not an entry
573 is selected by default is looked up in this hash.
575 =item 3. An array reference containing scalar values. Same as 1., just
576 for the case of C<multiple=1>.
578 =item 4. If C<default_value_key> is given: an array reference of hash
579 references. For each hash reference the value belonging to the key
580 C<default_value_key> is treated as one value to select by
581 default. Constructs a hash that's treated like 3.
583 =item 5. If C<default_value_key> is given: an array reference of
584 blessed objects. For each object the value returne from calling the
585 function named C<default_value_key> on the object is treated as one
586 value to select by default. Constructs a hash that's treated like 3.
590 5. also applies to single RDBO instances (due to 'wantarray'
591 shenanigans assigning RDBO's relationships to a hash key will result
592 in a single RDBO object being assigned instead of an array reference
593 containing that single RDBO object).
595 If the option C<with_optgroups> is set then this function expects
596 C<\@collection> to be one level deeper. The upper-most level is
597 translated into an HTML C<optgroup> tag. So the structure becomes:
601 =item 1. Array of array references. Each element in the
602 C<\@collection> is converted into an optgroup.
604 =item 2. The optgroup's C<label> attribute will be set to the
605 first element in the array element. The second array element is then
606 converted to a list of C<option> tags as described above.
610 Example for use of optgroups:
612 # First in a controller:
614 [ t8("First optgroup with three items"),
615 [ { id => 42, name => "item one" },
616 { id => 54, name => "second item" },
617 { id => 23, name => "and the third one" },
619 [ t8("Another optgroup, with a lot of items from Rose"),
620 SL::DB::Manager::Customer->get_all_sorted ],
623 # Later in the template:
624 [% L.select_tag('the_selection', COLLECTION, with_optgroups=1, title_key='name') %]
