### parseHtml [line 674]

`array parseHtml( string $module, array $input, array $values, boolean $restricted, &$tabindex, &$tabindexLink, string $scope, integer $tabindex, integer $tabindexLink)`

Takes a list of meta-HTML elements and prints the equivalent HTML output.

The modules are not allowed to display HTML code directly but return meta HTML code. This allows to have a common design for all module pages.
Meta HTML code is always returned as a three dimensional array[a][b][c] where a is the row number, b is the column number and c is is a data element.
Format of data elements:
A data element is an array which contains the data to display.
All data elements must contail a value "kind" which defines what kind of element should be displayed.
These are the possibilies for kind and what other options have to be added to the array:

- fieldset: Inserts a fieldset.
  - legend: The legend of the fieldset.
  - value: A data element. Can be used recursively.
- help: Adds a help link.
  - value: The help number for the help entry.
  - scope: The account type for the help entry.
- input: Adds a HTML input element.
  - name: The name of the element, will be used later as variable name when user input is returned.
  - type: allowed values: submit, reset, checkbox, text, password, file, hidden
  - checked: Boolean value, if true a checkbox will be checked. This value is only needed or checkboxes.
  - disabled: Boolean value, if true the element will be disabled.
  - size: The length of the input element, only used for text, password and file.
  - maxlength: The maximum size of the input element, only used for text, password and file.
  - value: The element will have this value as default. Button elements will have this as caption.
- select: This will add a select field.
  - name: The name of the element, will be used later as variable name when user input is returned.
  - multiple: Boolean value, if set to true the user can select more than one entry.
  - options: Array of string. This is the list of option values the user can select.
  - options_selected: Array of string. This is the list of pre selected elements, must contain values that are also in options.
  - descriptiveOptions: Boolean value, if set to true then all elements in options must be arrays themselves (array(value, description)) (default: false)
  - size: The size of the select field, if set to 1 a dropdown box will be displayed.
  - noSorting: If set to true then the entries will not be sorted. Default is false.
  - onchange: onchange event
- table: Adds a table. Can be used recursively.
  - value: A data element. Can be used recursively.
- text: Inserts a text element.
  - text: The text to display.
- textarea: Adds a multiline text field.
  - name: The name of the element, will be used later as variable name when user input is returned.
  - rows: Number of rows (required)
  - cols: Number of characters for each line (required)
  - readonly: Boolean value, if true the text field will be read only.
- image: Displays an image.
  - path: Path to the image
  - width: Width of the image
  - height: Height of the image
  - alt: Alt text of the image

Beneath those values a "td" value may be added. This has to be an array with one or more of these options:

- colspan: Like the HTML colspan attribute for td elements
- rowspan: Like the HTML rowspan attribute for td elements
- align: left/center/right/justify Like the HTML align attribute
- valign: top/middle/bottom Like the HTML valign attribute
- width: Like the HTML height attribute for td elements

Input buttons which should load a different subpage of a module must have a special name attribute:
name => 'form_subpage_' . <module name> . '_' . <subpage name> . '_' . <button name>

- <module name>: name of this account module (e.g. 'posixAccount')
- <subpage name>: name of next subpage (e.g. 'attributes')
- <button name>: a name to distinguish buttons (e.g. 'ok'/'cancel'/'back')

Example:

1. array(
2. array(
3. array("kind" => "text", "text" => "This is an example", "td" => array("colspan" => 3))
4. ),
5. array(
6. array("kind" => "text", "text" => "Input:"),
7. array("kind" => "input", "name" => "myinput", "type" => "text"),
8. array("kind" => "help", "value" => "42")
9. ),
10. array(
11. array("kind" => "input", "name" => 'form_subpage_myModule_attributes_back', "value" => _ ("Back"))
12. )
13. )

#### Tags:

return: | List of input field names and their type (name => type)

#### Parameters

string | $module | Name of account module
array | $input | List of meta-HTML elements
array | $values | List of values which override the defaults in $input (name => value)
boolean | $restricted | If true then no buttons will be displayed
integer | $tabindex | Start value of tabulator index for input fields
integer | $tabindexLink | Start value of tabulator index for links
string | $scope | Account type
| &$tabindex |
| &$tabindexLink |
