inputFile example

This example introduces intelligent file inputs. Besides the file input itself you can also use this element type to display a file thumbnail, a link to a file or even a "remove file" button - all these help a lot when you're building a form to modify such data.

The live form - submit it!

This is the config array for Clonefish which generates the form you've just seen.
Scroll at the bottom of this window to see how to use this array!


<?php

$config = Array(



  'inputfile1' => Array(

    'type'           => 'inputFile',

    'displayname'    => 'inputFile',

  ),



  'inputfile2' => Array(

    'type'           => 'inputFile',

    'displayname'    => 'inputFile<br>with a link (href setting)',

    'href'           => BASE_URI . 'files/inputfile.png',

  ),



  'inputfile3' => Array(

    'type'        => 'inputFile',

    'displayname' => 'inputFile<br>with thumbnail,<br> href and a delete button',

    'href'        => BASE_URI . 'files/inputfile.png',

    'thumbnail'   => BASE_URI . 'files/inputfile_thumb.png',

    'delete'      => 'somescript.php?target=delete&filename=inputfile_thumb.png'

  ),

);



?>

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 (
  'inputfile1' => NULL,
  'inputfile2' => NULL,
  'inputfile3' => NULL,
)

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).
