hey guys..

i try to create a form, but the "HiddenField" dont makes a value.

Page Type With Form Function

			$fieldset = new FieldSet(
				new TextField(
					$name = "Title",
					$title = "Betreff",
					$value = "Betreff eingeben"
				),
				new TextareaField(
					$name = "Message",
					$title = "Nachricht",
					$rows = 8,
					$cols = 3,
					$value = "Nachricht eingeben"
				),
				new OptionsetField(
					$name = "ToID",
					$title = "Alle Member",
					$source = $map,
					$value = $map[2]
				),
		 		new HiddenField (
					$name = "FromID",
					$value = "3"
				)
			);

This is my fieldset.. the value from "Title" and "Message" is shown in Sourcecode..

Browser Source Code

<div id="Title" class="field text "><label class="left" for="Form_SendenForm_Title">Betreff</label><span class="middleColumn"><input class="text" type="text" id="Form_SendenForm_Title" name="Title" value="Betreff eingeben" /></span></div>
<div id="Message" class="field textarea "><label class="left" for="Form_SendenForm_Message">Nachricht</label><span class="middleColumn"><textarea   id="Form_SendenForm_Message" name="Message" rows="8" cols="3">Nachricht eingeben</textarea></span></div>

But here look the HiddenField.. thereshould be a "3" in value.. bot nothing is there.

Browser Source Code

<input class="hidden" type="hidden" id="Form_SendenForm_FromID" name="FromID" value="" />

in my "saphire/forms/HiddenField.php" is this line.. but its like the line in TextField.php and there is works..

HiddenField.php

	function Field() {
		//if($this->name=="ShowChooseOwn")Debug::show($this->value);
		return "<input class=\"hidden\" type=\"hidden\" id=\"" . $this->id() . "\" name=\"{$this->name}\" value=\"" . $this->attrValue() . "\" />";
	}

HEEEELP!! :D

okay now it works!

I added the line "title = "test," and now it works!!

 		new HiddenField (
				$name = "FromID",
				$title= "test",
				$value = "3"
			)

Yeah, that's one of the most annoying things about HiddenField. It requires a Title attribute by virtue of its inheritance.

I'd skip the keyword arguments all together and just do:

new HiddenField('Name','','Value');

it's a lot cleaner.

yes it is. but my way is better to understand or to know exactly what is what..
the SS dokumentations are not very exactly.

http://doc.silverstripe.org/doku.php?id=hiddenfield

new HiddenField (
   $name = "hidden"
)

wow.. very helpful

http://doc.silverstripe.org/doku.php?id=recipes:simplesearch

		 new HiddenField("action_results", "Go")

this is from simple search.. does it work with only 2 statements or is this a bug in documentation?

but i love SS and as long i can fix all my bugs.. its very good CMS of course !

I'm experiencing something odd with this. Here's my code:

static $db = array(
        'Category' => 'Text'
   );
.
.
.
function getCMSFields() {
        $fields = parent::getCMSFields();        
		$fields->addFieldToTab('Root.Content.Main', new HiddenField('Category', '', 'Category 1'));

        return $fields;
    }

This should set the value to "Category 1" in the form. When I view the source there is no value set. However, if I change the name parameter from "Category" to anything else, I can see that the value gets properly set. Doesn't the name parameter have to match that in the $db array for the value to get set in the database?

SS 2.4.6

I know this questions is waaaay old, but if you're banging your head against it (like me) and are frustrated, try this.

If this doesn't work (as it didn't for me either):

    public function getCMSFields() {
        $fields = parent::getCMSFields();
        $fields->addFieldToTab('Root.Content.Main', new HiddenField('Name','Title','Value'));
		return $fields;
    }

Try setting the defaults as a static like this:

static $defaults = array(
        'Name' => 'Value'
    );

Solved my issue.
