- Access: public
Mref widget. Displays a select box with a list of options from another
table to choose from. Optionally configurable to be self-referencial and
organizes the options intuitively into a hierarchy.
Note: This widget requires a global $db database object to be available.
New in 1.2:
- Added a $self_ref property, to determine whether or not this widget is self-
referencial.
New in 1.4:
- Added the $popup and $popup_limit properties, which give some control over the
popup behaviour of this widget.
New in 1.6:
- Added an $addblank property.
Usage Example
<?php
$widget = new MF_Widget_mref ('name');
$widget->validation ('is "foo"');
$widget->error_message = 'Oops! This widget is being unruly!';
$widget->table = 'tablename';
$widget->primary_key = 'id';
$widget->display_column = 'title';
$widget->ref_column = 'refcolumn';
echo $widget->display ();
?>

Properties
$invalid_field = ''
Contains the name of the widget that did not validate during
the last call to the invalid () method.
$method
The value of the method attribute of the HTML form tag.
$method is actually an alias for $_attrs['method'].
$action
The value of the action attribute of the HTML form tag.
$action is actually an alias for $_attrs['action'].
$widgets = array ()
An array of form widgets.
$template
The optional template file or data used to customize the look
of the form.
$title
The title to be displayed at the top of the form.
$message
The initial message to be displayed at the top of the form.
$extra = ''
A way to pass extra parameters to the HTML form tag, for
example 'enctype="multipart/formdata"'.
$error_message
Contains the message from any internal errors.
$error_mode = 'single'
Determines the way in which error messages are displayed.
The default ('single') is to display the error message for the first
invalid field only. The other ('all') is to display a list of all
invalid fields with their corresponding error messages. Please note
that $error_mode 'all' assumes that a custom error message is provided
for every rule.
$invalid = array ()
A list of all invalid fields in the form, and their corresponding
error messages.
$submitted = false
Contains a true or false value as to whether the form has been
submitted successfully or not. An invalid form will contain false.
This value is used internally by the setValues() method.
$name
The name of the widget.
$_attrs = array ()
This contains a list of attributes of the HTML form tag.
$sendTo
The email address to send the form to in the default handler.
$sendFrom = ''
The email address to send the form from in the default handler.
$sendExtra = ''
Any extra parameters for the mail() function in the default handler.
$sendSubject = 'Mail Form'
The subject line of the email to send from the default handler.
$screenReply = 'Thank you. Your form has been sent.'
The response to return upon a successfully submitted form in the
default handler. Defaults to "Thank you. Your form has been sent."
$handler
The function or object method to use to handle the submitted form.
This function or method will be called by the run() method. Use the
setHandler() method to change this setting.
$uploadFiles = true
Whether to upload files automatically or to leave them for a custom
saving mechanism.
$verify_sender = false
Whether to verify the REQUEST_METHOD and HTTP_REFERER headers to make
it more difficult (although not impossible) for spammers to abuse your
form. Note that this can be enabled in a form's settings file under
the [Form] block via: verify_sender = yes
$clean_input = false
Whether to strip all HTML and PHP tags/code from all input parameters.
This is off by default because it would break forms with the Xed editor
by default, so it must be enabled as needed. Note that this can be
enabled in a form's settings file under the [Form] block via:
clean_input = yes
$blacklist = true
Whether to verify the remote address of the form submitter against
a list of invalid IP addresses in the database table
sitellite_form_blacklist so as to prevent repeated abuse from a single
source.
$verify_session = true
Whether to verify that the submitter can accept session data, which
helps ensure they are a legitimate human user. Passing session
verification requires cookies to be enabled for the submitter, which
may help prevent abuse in combination with the other abuse-prevention
techniques because a spambot may ignore the cookie, however this
restricts forms for legitimate visitors who have cookies disabled
in their browser (only a very small number of users disable cookies,
but some do). To disable for a single form, add verify_session = no
to its settings.php form.
$autosave = false
Whether this form should tie into Sitellite's autosave capabilities.
Please note that the autosave handler is only available to authenticated
users and not to anonymous forms.
$rule
The original unmodified rule definition.
$msg
The error message for this rule.
$type = 'mref'
This is the short name for this widget. The short name is
the class name minus the 'MF_Widget_' prefix.
$value
The rule value. This corresponds to the part of the rule
in double quotes (ie. type "value").
$negated = false
If a 'not' is present at the start of the rule, this will be
set to true, otherwise false.
$allowed = array ()
The access levels the user is allowed to access.
$nullable
Can this field contain a null value.
$tables = array ()
The list of elements that are to be displayed.
$allow_all_text = 'Allow All'
The text to display for the first element, which defaults to 'Allow All'.
$size = 3
Sets the size attribute of the select box that displays
the current attachments. Defaults to 3.
$addLink = 'addAttachment.php'
This is the link to send the 'Add' button to. Defaults to
'addAttachment.php'.
$removeLink = 'removeAttachment.php'
This is the link to send the 'Remove' button to. Defaults to
'removeAttachment.php'.
$format = '%Y-%m-%d'
This determines the format of the date stored in the hidden
field, and also the format submitted by the form widget.
$displayFormat = '%a, %e %b, %Y'
This determines the format of the date displayed to the user.

The default is 12 hours.
$fieldset = true
Set this to false if you don't want the fieldset and legend tags.
$align = 'vertical'
This determines the alignment of the buttons. The default is vertical,
which puts each button on its own row. Setting this to horizontal will put
the buttons all on the same row.
$_vertical_template = ' <tr>
<td colspan="2" class="field">
{if obj.fieldset}
<fieldset>
<legend{filter none}{invalid}{end filter}>{display_value}</legend>
{end if}
{loop obj.value}

'
$year
Unused and deprecated.
$month
Unused and deprecated.
$day
Unused and deprecated.
$lowest_year
The lowest year to be displayed in the year select box. Set to a
default value of 25 years ago by the constructor method.
$highest_year
The highest year to be displayed in the year select box. Set to a
default value of one year into the future by the constructor method.
$date
Unused and deprecated.
$time
Unused and deprecated.
$extensions = array ()
Contains a list of valid file extensions to display from the
directory.
$directory
Contains the directory to read the list of files from.
$data_value_DIRLIST
Contains the data value of this widget.
$show_viewbutton
Determines whether or not to display a 'view' link next to
the select box, which will pop up a view of the item from the list.
$web_path = ''
The web path to the directory in which to place the uploaded file.
$formname
Contains the name property of the current form. Required only if
$show_viewbutton is true.
$recursive
Whether or not the list should display recursively into sub-directories.
$path = false
Base directory path under which all images must be kept. If $setPath is
set to true and this is given a value, it will set a session variable
called "imagechooser_path" which will be used by the imagechooser app.
If no value is given for this, the default path used by the imagechooser
app is "/pix".
$mode = false
Specifies a mode to chmod() the newly uploaded file to during
the move() method. The mode is also known as the permissions of the
file. Must be set as a 4-digit octal value with the first digit on
the left being a zero (0), for example 0755. See the PHP documentation
for the chmod() function for more information.
$user = false
Specifies a user to chown() the newly uploaded file to during
the move() method. This is not likely to work on most systems, but
it exists for the few strange (and highly suspect) configurations
where it will. See the PHP documentation for the chown() function
for more information.
$group = false
Specifies a group to chgrp() the newly uploaded file to during
the move() method. Can only be changed to any group that the PHP user
belongs to. See the PHP documentation for the chgrp() function for
more information.
$clear = false
This determines whether to provide a "Clear" button when a file exists
in an edit form, so that the current value can be reset without being
replaced.
$hideInSearches = true
This allows you to specify whether or not you want this widget to
show in search results (used primarily in the Sitellite CMS database manager)
so that it can be hidden in the form, but not everywhere. Defaults to
true, as in "yes, hide it everywhere".
$field = ''
The field to use to determine the key in the key/value $set property.
$setPath = true
Tells imagechooser whether or not to set the session variable
"imagechooser_path" upon display() of this widget.
$filter = false
A filter function to apply to the value before displaying it. Note that
htmlentities_compat() is still called afterwards.
$filter_import = false
A library to import which contains the filter function.
$htmlentities = true
Set this to false to skip calling htmlentities_compat() on the displayed
data.
$table
Contains the table to read from.
$self_ref
Whether or not this widget is self-referencial.
$primary_key
The column in the other table that is the primary key.
$display_column
The column in the other table that should be shown in the select box.
$ref_column
The column in the current table that refers to the other table.
$addblank
Whether or not to add a blank line to the list. $addblank is
useful in the Sitellite CMS because saf.App.Versioning returns the
column value as NULL if $nullable is set to true, and getData() is
called automatically by display(), so there's no chance to add a
blank array element at the bottom of the list.
$popup
If true, this will prompt a popup to occur at $popup_limit number of options
in the Ref, so that they all aren't loaded at once into the select box. This is true
by default. It is good for references to large tables. This feature is Sitellite
Content Manager specific.
$popup_limit
This determines the limit at which a popup occurs instead of a select box,
if $popup is set to true.
