Class: portfolio_add_button - X-Ref
Use this to add a portfolio button or icon or form to a page.These class methods do not check permissions. the caller must check permissions first.
Later, during the export process, the caller class is instantiated and the check_permissions method is called
If you are exporting a single file, you should always call set_format_by_file($file)
This class can be used like this:
<code>
$button = new portfolio_add_button();
$button->set_callback_options('name_of_caller_class', array('id' => 6), 'yourcomponent'); eg. mod_forum
$button->render(PORTFOLIO_ADD_FULL_FORM, get_string('addeverythingtoportfolio', 'yourcomponent'));
</code>
or like this:
<code>
$button = new portfolio_add_button(array('callbackclass' => 'name_of_caller_class', 'callbackargs' => array('id' => 6), 'callbackcomponent' => 'yourcomponent')); eg. mod_forum
$somehtml .= $button->to_html(PORTFOLIO_ADD_TEXT_LINK);
</code>

| __construct($options=null) X-Ref |
| Constructor. Either pass the options here or set them using the helper methods. Generally the code will be clearer if you use the helper methods. param: array $options keyed array of options: |
| set_callback_options($class, array $argarray, $component) X-Ref |
| Function to set the callback options param: string $class Name of the class containing the callback functions param: array $argarray This can be an array or hash of arguments to pass param: string $component This is the name of the component in Moodle, eg 'mod_forum' |
| set_formats($formats=null) X-Ref |
| Sets the available export formats for this content. This function will also poll the static function in the caller class and make sure we're not overriding a format that has nothing to do with mimetypes. Eg: if you pass IMAGE here but the caller can export LEAP2A it will keep LEAP2A as well. param: array $formats if the calling code knows better than the static method on the calling class (base_supported_formats). |
| reset_formats() X-Ref |
| Reset formats to the default, which is usually what base_supported_formats returns |
| set_format_by_file(stored_file $file, $extraformats=null) X-Ref |
| If we already know we have exactly one file, bypass set_formats and just pass the file so we can detect the formats by mimetype. param: stored_file $file file to set the format from param: array $extraformats any additional formats other than by mimetype |
| set_format_by_intended_file($extn, $extraformats=null) X-Ref |

| Returns a drop menu with a list of available instances. param: array $instances array of portfolio plugin instance objects - the instances to put in the menu param: array $callerformats array of PORTFOLIO_FORMAT_XXX constants - the formats the caller supports (this is used to filter plugins) param: string $callbackclass the callback class name - used for debugging only for when there are no common formats param: string $mimetype if we already know we have exactly one file, or are going to write one, pass it here to do mime filtering. param: string $selectname the name of the select element. Optional, defaults to instance. param: bool $return whether to print or return the output. Optional, defaults to print. param: bool $returnarray if returning, whether to return the HTML or the array of options.

| portfolio_instances($visibleonly=true, $useronly=true) X-Ref |
| Return all portfolio instances param: bool $visibleonly Don't include hidden instances. Defaults to true and will be overridden to true if the next parameter is true param: bool $useronly Check the visibility preferences and permissions of the logged in user.

| portfolio_format_from_mimetype($mimetype) X-Ref |
| Deduce export format from file mimetype This function returns the revelant portfolio export format which is used to determine which portfolio plugins can be used for exporting this content according to the given mime type this only works when exporting exactly <b>one</b> file, or generating a new one (like a pdf or csv export) param: string $mimetype (usually $file->get_mimetype()) return: string the format constant (see PORTFOLIO_FORMAT_XXX constants) |

| portfolio_most_specific_formats($specificformats, $generalformats) X-Ref |
| Return the combination of the two arrays of formats with duplicates in terms of specificity removed and also removes conflicting formats. Use case: a module is exporting a single file, so the general formats would be FILE and MBKP while the specific formats would be the specific subclass of FILE based on mime (say IMAGE) and this function would return IMAGE and MBKP param: array $specificformats array of more specific formats (eg based on mime detection) param: array $generalformats array of more general formats (usually more supported) return: array merged formats with dups removed |
