selectDynamic Multiple example

In this example we have an extra parameter passed to our form class, which is the ID of a writer from our . Using the 'valuesql' parameter, CloneFish pre-selects options of this multiple select (values are taken from the ). Additionally, using the 'values' array, you can preset values of your choice - even dynamically, since it's just a PHP array, which is easy to fill with values.

This is the config array for Clonefish which generates the form you've just seen.

<?php

$config = Array(



  'parameter' => Array(

    'type'    => 'inputHidden',

    'value'   => @$_REQUEST['parameter'],

  ),



  'booksofawriter[]' => Array(

    'type'           => 'selectDynamic',

    'displayname'    => 'This is a dynamic multiple select',

    'html'           => 'multiple="multiple" size="5"',

    'sql'            => 'SELECT id, title FROM books',

    values         => 

      Array( 

        0 => 'choose nothing', 

      ),

    'valuesql'       => 

      "SELECT bookid

       FROM booksofawriter

       WHERE writerid = '%s'",

    'value'          => '0'

  )



);



?>

Usage example

To create a form using this array you'll only need a few lines of code:

<?php // create the form object $clonefish = new clonefish( 'loginform', 'test.php', 'POST' ); // setup codepage so your data will be handled // perfectly by the appropriate string functions $clonefish->codepage = 'utf-8'; $clonefish->multibytesupport = 'multibyteutf8'; // add the form elements (fields) pre-filled with // values from $_POST $clonefish->addElements( $config, $_POST, get_magic_quotes_gpc() ); // validate the form if the form has been submitted if ( count( $_POST ) && $clonefish->validate() ) { // form is valid, go and store values in database, etc. // $clonefish->getElementValues() provides a // normalized value array. } else // if the form wasn't submitted yet or the validation // had failed, show the form (automatically // including error messages) echo "<html><body>" . $clonefish->getHTML() . "</body></html>"; ?>

Data dump

Below are the dumps of some PHP variables - submit the form to see the changes!

Contents of the $_POST array:
$_POST = array (
)

Results of a $clonefish->getElementValues() call:
array (
  'parameter' => '1',
  'booksofawriter' => '0',
)

There are cases when the above arrays are different. This is not a bug, but a feature: clonefish was written to help with everyday form hassles (like avoiding the missing value of an unchecked checkbox or compiling the whole date string from date selector fields).
