HTML::FormFu::Element::Repeatable - repeatable block element --- elements: - type: Repeatable elements: - name: foo - name: bar Calling "$element->repeat(2)" would result in the following markup: <div> <input name="foo" type="text" /> <input name="bar" type="text" /> </div> <div> <input name="foo" type="text" /> <input name="bar" type="text" /> </div> Provides a way to extend a form at run-time, by copying and repeating its child elements. The elements intended for copying must be added before "repeat" is called. Although the Repeatable element inherits from Block, it doesn't generate a block tag around all the repeated elements - instead it places each repeat of the elements in a new Block element, which inherits the Repeatable's display settings, such as "attributes" and "tag".

repeat
Arguments: [$count] Return Value: $arrayref_of_new_child_blocks This method creates $count number of copies of the child elements. If no argument $count is provided, it defaults to 1. Note that "$form->process" will call "repeat" automatically to ensure the initial child elements are correctly set up - unless you call "repeat" manually first, in which case the child elements you created will be left untouched (otherwise "process" would overwrite your changes). Any subsequent call to "repeat" will delete the previously copied elements before creating new copies - this means you cannot make repeated calls to "repeat" within a loop to create more copies. Each copy of the elements returned are contained in a new Block element. For example, calling "$element->repeat(2)" on a Repeatable element containing 2 Text fields would return 2 Block elements, each containing a copy of the 2 Text fields.

counter_name
Arguments: $name If true, the "query" in HTML::FormFu will be searched during "process" in HTML::FormFu for a parameter with the given name. The value for that parameter will be passed to "repeat", to automatically create the new copies. If "increment_field_names" is true (the default), this is essential: if the elements corresponding to the new fieldnames (foo_1, bar_2, etc.) are not present on the form during "process" in HTML::FormFu, no Processors (Constraints, etc.) will be run on the fields, and their values will not be returned by "params" in HTML::FormFu or "param" in HTML::FormFu.

increment_field_names
Arguments: $bool Default Value: 1 If true, then any copies of fields whose name contains a 0, will have the 0 replaced by it's "repeatable_count" value. --- elements: - type: Repeatable increment_field_names: 1 elements: - name: foo_0 - name: bar_0 Calling "$element->repeat(2)" would result in the following markup: <div> <input name="foo_1" type="text" /> <input name="bar_1" type="text" /> </div> <div> <input name="foo_2" type="text" /> <input name="bar_2" type="text" /> </div> See also "counter_name".

repeatable_count
This is set on each new Block element returned by "repeat", starting at number 1. Because this is an 'inherited accessor' available on all elements, it can be used to determine whether any element is a child of a Repeatable element.

attributes

attrs
Any attributes set will be passed to every repeated Block of elements. --- elements: - type: Repeatable attributes: class: rep elements: - name: foo Calling "$element->repeat(2)" would result in the following markup: <div class="rep"> <input name="foo" type="text" /> </div> <div class="rep"> <input name="foo" type="text" /> </div> See "attributes" in HTML::FormFu for details.

tag
The "tag" value will be passed to every repeated Block of elements. --- elements: - type: Repeatable tag: span elements: - name: foo Calling "$element->repeat(2)" would result in the following markup: <span> <input name="foo" type="text" /> </span> <span> <input name="foo" type="text" /> </span> See "tag" in HTML::FormFu::Element::block for details.

auto_id
As well as the usual subtitutions, any instances of %r will be replaced with the value of "repeatable_count". See "auto_id" in HTML::FormFu::Element::block for further details. --- elements: - type: Repeatable auto_id: "%n_%r" elements: - name: foo Calling "$element->repeat(2)" would result in the following markup: <div> <input name="foo" id="foo_1" type="text" /> </div> <div> <input name="foo" id="foo_2" type="text" /> </div>
