    <title>Standard Form Elements Shipped With Zend Framework</title>

    <para>
        Zend Framework ships with concrete element classes covering most HTML
        form elements. Most simply specify a particular view helper for use when
        decorating the element, but several offer additional functionality. The
        following is a list of all such classes, as well as descriptions of the
        functionality they offer.
    </para>

    <sect2 id="zend.form.standardElements.button">
        <title>Zend_Form_Element_Button</title>

        <para>
            Used for creating HTML button elements,
            <classname>Zend_Form_Element_Button</classname> extends <link
                linkend="zend.form.standardElements.submit">Zend_Form_Element_Submit</link>,
            specifying some custom functionality. It specifies the 'formButton'
            view helper for decoration.
        </para>

        <para>
            Like the submit element, it uses the element's label as the element
            value for display purposes; in other words, to set the text of the
            button, set the value of the element. The label will be translated
            if a translation adapter is present.
        </para>

        <para>
            Because the label is used as part of the element, the button element
            uses only the <link
                linkend="zend.form.standardDecorators.viewHelper">ViewHelper</link>
            and <link
                linkend="zend.form.standardDecorators.dtDdWrapper">DtDdWrapper</link>
            decorators.
        </para>

        <para>
            After populating or validating a form, you can check if the given
            button was clicked using the <code>isChecked()</code> method.
        </para>
    </sect2>

    <sect2 id="zend.form.standardElements.captcha">
        <title>Zend_Form_Element_Captcha</title>

        <para>
            CAPTCHAs are used to prevent automated submission of forms by bots
            and other automated processes.
        </para>

        <para>
            The Captcha form element allows you to specify which <link
                linkend="zend.captcha.adapters">Zend_Captcha adapter</link> you
            wish to utilize as a form CAPTCHA. It then sets this adapter as a
            validator to the object, and uses a Captcha decorator for rendering
            (which proxies to the CAPTCHA adapter).
        </para>

        <para>
            Adapters may be any adapters in <classname>Zend_Captcha</classname>, as well
            as any custom adapters you may have defined elsewhere. To allow
            this, you may pass an additional plugin loader type key, 'CAPTCHA'
            or 'captcha', when specifying a plugin loader prefix path:
        </para>

        <programlisting language="php"><![CDATA[
$element->addPrefixPath('My_Captcha', 'My/Captcha/', 'captcha');
]]></programlisting>

        <para>
            Captcha's may then be registered using the <code>setCaptcha()</code>
            method, which can take either a concrete CAPTCHA instance, or the
            short name of a CAPTCHA adapter:
        </para>

        <programlisting language="php"><![CDATA[
// Concrete instance:
$element->setCaptcha(new Zend_Captcha_Figlet());

// Using shortnames:
$element->setCaptcha('Dumb');
]]></programlisting>

        <para>
            If you wish to load your element via configuration, specify either
            the key 'captcha' with an array containing the key 'captcha', or
            both the keys 'captcha' and 'captchaOptions':
        </para>

        <programlisting language="php"><![CDATA[
// Using single captcha key:
$element = new Zend_Form_Element_Captcha('foo', array(
    'label' => "Please verify you're a human",
    'captcha' => array(
        'captcha' => 'Figlet',
        'wordLen' => 6,
        'timeout' => 300,
    ),
));

// Using both captcha and captchaOptions:
$element = new Zend_Form_Element_Captcha('foo', array(
    'label' => "Please verify you're a human"
    'captcha' => 'Figlet',
    'captchaOptions' => array(
        'captcha' => 'Figlet',
        'wordLen' => 6,
        'timeout' => 300,
    ),
));
]]></programlisting>

        <para>
            The decorator used is determined by querying the captcha adapter. By
            default, the <link
                linkend="zend.form.standardDecorators.captcha">Captcha
                decorator</link> is used, but an adapter may specify a different
            one via its <code>getDecorator()</code> method.
        </para>

        <para>
            As noted, the captcha adapter itself acts as a validator for the
            element. Additionally, the NotEmpty validator is not used, and the
            element is marked as required. In most cases, you should need to do
            nothing else to have a captcha present in your form.
        </para>
    </sect2>

    <sect2 id="zend.form.standardElements.checkbox">
        <title>Zend_Form_Element_Checkbox</title>

        <para>
            HTML checkboxes allow you return a specific value, but basically
            operate as booleans. When checked, the checkbox's value is submitted.
            When the checkbox is not checked, nothing is submitted. Internally,
            <classname>Zend_Form_Element_Checkbox</classname> enforces this state.
        </para>

        <para>
            By default, the checked value is '1', and the unchecked value '0'.
            You can specify the values to use using the
            <code>setCheckedValue()</code> and <code>setUncheckedValue()</code>
            accessors, respectively. Internally, any time you set the value, if
            the provided value matches the checked value, then it is set, but
            any other value causes the unchecked value to be set.
        </para>

        <para>
            Additionally, setting the value sets the <code>checked</code>
            property of the checkbox. You can query this using
            <code>isChecked()</code> or simply accessing the property. Using the
            <code>setChecked($flag)</code> method will both set the state of the
            flag as well as set the appropriate checked or unchecked value in the
            element. Please use this method when setting the checked state of a
            checkbox element to ensure the value is set properly.
        </para>

        <para>
            <classname>Zend_Form_Element_Checkbox</classname> uses the 'formCheckbox' view
            helper. The checked value is always used to populate it.

        <title>Zend_Form_Element_File</title>

        <para>
            The File form element provides a mechanism for supplying file upload
            fields to your form. It utilizes <link
                linkend="zend.file.transfer.introduction">Zend_File_Transfer</link>
            internally to provide this functionality, and the
            <code>FormFile</code> view helper as also the <code>File</code>
            decorator to display the form element.
        </para>

        <para>
            By default, it uses the <code>Http</code> transfer adapter, which
            introspects the <code>$_FILES</code> array and allows you to attach
            validators and filters. Validators and filters attached to the form
            element are in turn attached to the transfer adapter.
        </para>

        <example id="zend.form.standardElements.file.usage">
            <title>File form element usage</title>

            <para>
                The above explanation of using the File form element may seem
                arcane, but actual usage is relatively trivial:
            </para>

            <programlisting language="php"><![CDATA[
$element = new Zend_Form_Element_File('foo');
$element->setLabel('Upload an image:')

// limit to 100K
$element->addValidator('Size', false, 102400);
// only JPEG, PNG, and GIFs
$element->addValidator('Extension', false, 'jpg,png,gif');
$form->addElement($element, 'foo');
]]></programlisting>

            <para>
                You also need to ensure that the correct encoding type is provided to
                the form; you should use 'multipart/form-data'. You can do this
                by setting the 'enctype' attribute on the form:
            </para>

            <programlisting language="php"><![CDATA[
$form->setAttrib('enctype', 'multipart/form-data');
]]></programlisting>

            <para>
                After the form is validated successfully, you must receive the file
                to store it in the final destination using <code>receive()</code>. Additionally you
                can determinate the final location using <code>getFileName()</code>:
            </para>

            <programlisting language="php"><![CDATA[
if (!$form->isValid) {
    print "Uh oh... validation error";
}

if (!$form->foo->receive()) {
    print "Error receiving the file";
}

$location = $form->foo->getFileName();
]]></programlisting>

        </example>

        <note>
            <title>Default Upload Location</title>

            <para>
                By default, files are uploaded to the system temp directory.
            </para>
        </note>

        <note>
            <title>File values</title>

            <para>
                Within HTTP a file element has no value. For this reason and because of
                security concerns <code>getValue()</code> returns only the uploaded filename
                and not the complete path. If you need the file path, call
                <code>getFileName()</code>, which returns both the path and the name of the file.
            </para>
        </note>

        <para>
            Per default the file will automatically be received when you call
            <code>getValues()</code> on the form. The reason behind this behaviour is, that the
            file itself is the value of the file element.
        </para>

        <programlisting language="php"><![CDATA[
$form->getValues();
]]></programlisting>

        <note>
            <para>
                Therefor another call of <code>receive()</code> after calling
                <code>getValues()</code> will not have an effect. Also creating a instance of
                <classname>Zend_File_Transfer</classname> will not have an effect as there no file
                anymore to receive.
            </para>
        </note>

        <para>
            Still, sometimes you may want to call <code>getValues()</code> without receiving the
            file. You can archive this by calling <code>setValueDisabled(true)</code>. To get the
            actual value of this flag you can call <code>isValueDisabled()</code>.
        </para>

        <example id="zend.form.standardElements.file.retrievement">
            <title>Explicit file retrievement</title>

            <para>
                First call <code>setValueDisabled(true)</code>.
            </para>

            <programlisting language="php"><![CDATA[
$element = new Zend_Form_Element_File('foo');
$element->setLabel('Upload an image:')
        ->setDestination('/var/www/upload')
        ->setValueDisabled(true);
]]></programlisting>

            <para>
                Now the file will not be received when you call <code>getValues()</code>.
                So you must call <code>receive()</code> on the file element, or an instance of
                <classname>Zend_File_Transfer</classname> yourself.
            </para>

            <programlisting language="php"><![CDATA[
$values = $form->getValues();

        </example>

        <para>
            There are several states of the uploaded file which can be checked

                    <code>isFiltered()</code>: Checks if the filters have already
                    been applied to the file element or not.
                </para>
            </listitem>
        </itemizedlist>

        <para>
            <classname>Zend_Form_Element_File</classname> also supports multiple files.
            By calling the <code>setMultiFile($count)</code> method you can set
            the number of file elements you want to create. This keeps you
            from setting the same settings multiple times.
        </para>

            <title>Setting multiple files</title>

            <para>
                Creating a multifile element is the same as setting a single
                element. Just call <code>setMultiFile()</code> after the element is created:

            <para>
                You now have 3 identical file upload elements

            <title>File elements in Subforms</title>

            <para>
                When you use file elements in subforms you must set unique names.
                For example, if you name a file element in subform1 "file", you must give
                any file element in subform2 a different name.
            </para>

            <para>
                If there are 2 file elements with the same name, the second
                element is not be displayed or submitted.
            </para>

            <para>
                Additionally, file elements are not rendered within the sub-form. So when
                you add a file element into a subform, then the element will be rendered
                within the main form.
            </para>
        </note>

        <para>
            To limit the size of the file uploaded, you can
            specify the maximum file size by setting the <code>MAX_FILE_SIZE</code>
            option on the form. When you set this value by using the
            <code>setMaxFileSize($size)</code> method, it will be rendered with the
            file element.
        </para>

            Hidden elements inject data that should be submitted, but that should not manipulated by

        <para>
            This element provides protection from CSRF attacks on forms,
            ensuring the data is submitted by the user session that generated
            the form and not by a rogue script. Protection is achieved by adding
            a hash element to a form and verifying it when the form is
            submitted.
        </para>

        <para>
            The name of the hash element should be unique. We recommend using
            the <literal>salt</literal> option for the element- two hashes with
            same names and different salts would not collide:

            You can set the salt later using the <code>setSalt($salt)</code>
            method.
        </para>

        <para>
            Internally, the element stores a unique identifier using
            <classname>Zend_Session_Namespace</classname>, and checks for it at
            submission (checking that the TTL has not expired). The 'Identical'
            validator is then used to ensure the submitted hash matches the
            stored hash.
        </para>

        <para>

        <para>
            Images need an image source. <classname>Zend_Form_Element_Image</classname>
            allows you to specify this by using the <code>setImage()</code>

            when submitting the image using the <code>setImageValue()</code> accessor
            (or 'imageValue' configuration key). When the value set for the
            element matches the <code>imageValue</code>, then the accessor
            <code>isChecked()</code> will return true.
        </para>

        <para>
            Image elements use the
            <link linkend="zend.form.standardDecorators.image">Image
                Decorator</link> for rendering, in addition to the standard Errors,
            HtmlTag, and Label decorators. You can optionally specify a tag to
            the <code>Image</code> decorator that will then wrap the image
            element.

        <title>Zend_Form_Element_MultiCheckbox</title>

        <para>
            Often you have a set of related checkboxes, and you wish to group
            the results. This is much like a <link
                linkend="zend.form.standardElements.multiselect">Multiselect</link>,
            but instead of them being in a dropdown list, you need to show
            checkbox/value pairs.
        </para>

        <para>
            <classname>Zend_Form_Element_MultiCheckbox</classname> makes this a snap. Like
            all other elements extending the base Multi element, you can specify
            a list of options, and easily validate against that same list. The
            'formMultiCheckbox' view helper ensures that these are returned as
            an array in the form submission.
        </para>

        <para>
            By default, this element registers an <code>InArray</code> validator
            which validates against the array keys of registered options. You
            can disable this behavior by either calling
            <code>setRegisterInArrayValidator(false)</code>, or by passing a
            false value to the <code>registerInArrayValidator</code>
            configuration key.
        </para>

        <para>
            You may manipulate the various checkbox options using the following

        <para>
            To mark checked items, you need to pass an array of values to
            <code>setValue()</code>. The following will check the values "bar"
            and "bat":

        <title>Zend_Form_Element_Multiselect</title>

        <para>
            XHTML <code>select</code> elements allow a 'multiple' attribute,

            Password elements are basically normal text elements -- except that

            messages or the element itself when the form is re-displayed.
        </para>

        <para>
            <classname>Zend_Form_Element_Password</classname> achieves this by calling
            <code>setObscureValue(true)</code> on each validator (ensuring that
            the password is obscured in validation error messages), and using
            the 'formPassword' view helper (which does not display the value
            passed to it).

        <para>
            Reset buttons are typically used to clear a form, and are not part

            As such, the label is used for the button display, and will be
            translated if a translation adapter is present. It utilizes only the
            'ViewHelper' and 'DtDdWrapper' decorators, as there should never be
            error messages for such elements, nor will a label be necessary.

        <para>
            Submit buttons are used to submit a form. You may use multiple
            submit buttons; you can use the button used to submit the form to
            decide what action to take with the data submitted.
            <classname>Zend_Form_Element_Submit</classname> makes this decisioning easy,
            by adding a <code>isChecked()</code> method; as only one button
            element will be submitted by the form, after populating or
            validating the form, you can call this method on each submit button
            to determine which one was used.
        </para>

        <para>
            <classname>Zend_Form_Element_Submit</classname> uses the label as the "value"
            of the submit button, translating it if a translation adapter is
            present. <code>isChecked()</code> checks the submitted value against
            the label in order to determine if the button was used.

            decorators to render the element. No label decorator is used, as the
            button label is used when rendering the element; also, typically,
            you will not associate errors with a submit element.

            By far the most prevalent type of form element is the text element,

            size limits as dictated by your server or PHP).
            <classname>Zend_Form_Element_Textarea</classname> uses the 'textArea' view
            helper to display such elements, placing the value as the content of
