During the development of components or modules for Joomla, you will need to create fields of form. Joomla API proposes functions which will facilitate the task to you.

Program of this first part:

• Lists of integers
• Lists of month

1) Lists of integers :

A - Syntax :

string integerSelectList (int $start, int $end, int $inc, string $tag_name, string $tag_attribs, mixed $selected [, string $format])

$start: it is the first integer of the list
$end: it is the last integer of the list
$inc: it is the step of incrementing between 2 integers of the list
$tag_name: corresponds to the value which will have the attribute “name” list
$tag_attribs: corresponds to the list of attributes you want to associate to the list (example: size, class, OnClick, etc…)
$selected: corresponds to the value selected by default
$format: the format of posting of the integers in the list defines

B - Code example :

//Create the object
$integerlist = mosHTML:: integerSelectList (-5, 10, 1, “integer_list”, “size= " 3” class= " inputbox””, 0, “%02d”);

//Display the list
echo $integerlist;

C - HTML code returned by the example:

<select name= " “integer_list”” size= " 3 " class= " inputbox " >
<option value= " - 5 " >-5</option>
<option value= " - 4 " >-4</option>
<option value= " - 3 " >-3</option>
<option value= " - 2 " >-2</option>
<option value= " - 1 " >-1</option>
<option value= " 00 " selected= " selected " >00</option>
<option value= " 01 " >01</option>
<option value= " 02 " >02</option>
<option value= " 03 " >03</option>
<option value= " 04 " >04</option>
<option value= " 05 " >05</option>
<option value= " 06 " >06</option>
<option value= " 07 " >07</option>
<option value= " 08 " >08</option>
<option value= " 09 " >09</option>
<option value= " 10 " >10</option>
</select>

D - Example result :

-5 -4 -3 -2 -1 00 01 02 03 04 05 06 07 08 09 10

2) Lists of month :

A - Syntax :

string monthSelectList (string $tag_name, string $tag_attribs, mixed $selected)

$tag_name: corresponds to the value which will have the attribute “name” list $tag_attribs: corresponds to the list of attributes you want to associate to the list (example: size, class, OnClick, etc…)
$selected: corresponds to the month selected by default

B - Code example :

//Create the object
$listmonth = mosHTML:: monthSelectList (“list_month”, “class= " inputbox””, “08”);

//Display the list
echo $listmonth;

C - HTML code returned by the example:

<select name= " month " class= " inputbox " > <option value= " 01 " >January</option>

<option value= " 02 " >February</option>
<option value= " 03 " >March</option>
<option value= " 04 " >April</option>
<option value= " 05 " >May</option>
<option value= " 06 " >June</option>
<option value= " 07 " >July</option>
<option value= " 08 " selected= " selected " >August</option>
<option value= " 09 " >September</option>
<option value= " 10 " >October</option>
<option value= " 11 " >November</option>
<option value= " 12 " >December</option>
</select>

D - Example result :

January February March April May June July August September October November December
