Manual  /  Functions  /  Data handling  /  SetValue

Arguments:

Name	Description
$field	The field where you want to set a value in
$value	The value you want to set
$overwriteCurrentValue	Should a posted value or a value from the database also been overwritten?

Description:

This function works on all fields! Needs to be placed before the field in order to keep the altered value in a multipage form!

In fields which can have multiple values (like a listfield), you can select multiple items in two ways:

1. Give an array


2. Give the items seperated with a comma (,)

Example

<?php // include the class include("FH3/class.FormHandler.php"); // make a new formhandler object $form = new FormHandler(); // set a default value $form -> setValue("name", "Enter your name..."); // textfield $form -> textField("Name", "name", FH_STRING); // button $form -> submitButton(); // set the 'commit after form' function $form -> onCorrect("doRun"); // flush the form $form -> flush(); // the 'commit after form' function function doRun( $data )  {     return "Hello ". $data["name"]; } ?>

The result is:

Example 2: Setting more then 1 value

<?php // include the class include("FH3/class.FormHandler.php"); // options to use in the listfield $options = array(   1 => "option 1",   2 => "option 2",   3 => "option 3" ); // make a new formhandler object $form = new FormHandler(); // listfield $form -> listField("Options", "options", $options, FH_NOT_EMPTY, true); // set a default value // (We have to set the index of the array, // because we have set the option useArrayKeyAsValue to true. // If we had not done that, we had to set // the real "value" of the options array) $form -> setValue( "options", "1, 3" ); // This was also correct!! // $form -> setValue( "options", array(1, 3) ); // button $form -> submitButton(); // set the 'commit after form' function $form -> onCorrect("doRun"); // flush the form $form -> flush(); // the 'commit after form' function function doRun( $data )  {     global $options;     $msg = "Selected: \n";     // show the selected options     foreach($data['options'] as $id)      {         $msg .= " - ".$options[$id]." \n";     }     return $msg; } ?>
