Forum Index / Feedback / arrays in the POST

Can FormHandler handle, process, validate, etc. fields that create arrays after being posted. Like <input type="text" name="bla[1]"> <input type="text" name="bla[2]"> <input type="checkbox" name="id[]"> <input type="checkbox" name="id[]"> <input type="checkbox" name="id[]"> ?

Like

<input type="text" name="bla[1]">
<input type="text" name="bla[2]">

<input type="checkbox" name="id[]">
<input type="checkbox" name="id[]">
<input type="checkbox" name="id[]">

?

No, FormHandler cannot (yet) handle arrays as names, but the second example you gave (checkboxes) is build in and will be generated when you give an array as value to the checkbox method.

Ah, but i guess something like this:

<input type="checkbox" name="id[5]">
<input type="checkbox" name="id[21]">

is not possible ... or is it?

It is particularly usefull when working with database-data. That's why i'm asking it (and why i consider it a vital function)

This is possible:

<?php

$itemsFromDB = array(
  1 => "item1",
  2 => "item2",
  4 => "item3",
  9 => "item4"
);

$form->checkBox("Items", "items", $itemsFromDB, true);

/*
Now the user can select a number of checkboxes. The one he selected will be in the array of the field's result. e.g.:
*/

function doRun( $data ) {
    print_r($data["items"]);
    // prints somehting like array( 1, 4, 9 )
    // depending on what the user selected :-)
}
?>

How can i do this with a textfield? already before the form is printing?

I want this because i want to use it by this webpage:
http://d3dgroep2.glrdmd.eu/album.php

I have now this script

<?php
include("FH3/class.FormHandler.php");

$itemsFromDB = array(
  1 => "item1",
  2 => "item2",
  4 => "item3",
  9 => "item4"
);
$form =& new FormHandler();

//$form->checkBox("Items", "items", $itemsFromDB, NULL, true);
$form -> setValue("items", "Enter your name...");
$form->textField( "Items", "items", FH_STRING, 20, 40);

// button for submitting
$form->submitButton();

// set the 'commit-after-form' function
$form->onCorrect('doRun');

// display the form
$form->flush();

/*
Now the user can select a number of checkboxes. The one he selected will be in the array of the field's result. e.g.:
*/

function doRun( $data ) {
    echo "test";
    print_r($data["items"]);
    // prints somehting like array( 1, 4, 9 )
    // depending on what the user selected :-)
}
?>

it is not possible to use "array" fields with textfields. Sorry, FH does not support that...
