Model	Extends	Table	Path
Labels_Model	Plain_Model	labels	/application/models/labels_model.php

Loading the model

$this->load->model('labels_model', 'labels');

Properties

Property	Visibility	Default Value	Description
$sort	Public	created_on ASC	The default sort direction for reads.

Methods

__construct - Public

Called automatically which in turn calls the parent constructor and sets the model $data_types properties.

---

create - Public

Used to create new records in the labels table. There are two types of labels, smart and label. The latter is a system-level only, normal label. The smart label can be a default system-level smart label or a user defined system-label.

Arguments (Overall)

Variable	Type	Default	Required	Description
$options	array	array()	Yes	An associative array that contains the column names and the values for the record to be created. Array keys are the column names for each value.

Arguments (System-Level Normal Label)

If creating a system-level normal label below are the fields that can be submitted.

Variable	Type	Default	Required	Description
$options.name	String	N/A	Yes	The name of the label.
$options.slug	String	N/A	Yes	The unique slug used for lookups. To easily create this use the [data helper method of `generateSlug`](Helpers-Data.md).
$options.active	Number	1	No	Set to 1 for active, or 0 for inactive.

Arguments (Smart Labels)

If creating a system-level or user-defined smart labels below are the fields that can be submitted.

Variable	Type	Default	Required	Description
$options.smart_label_id	String	N/A	Yes	The `labels.label_id` of the normal label to apply when this rule is matched.
$options.domain	String	N/A	Yes	The FQDN (IE: google.com)
$options.path	String	Null	No	The path to match with the domain.
$options.smart_key	MD5	N/A	Yes	The MD5 hash of the domain + path used for easy lookups. To easily create this use the [data helper method of `getSmartLabelInfo`](Helpers-Data.md).
$options.active	Number	1	No	Set to 1 for active, or 0 for inactive.
$options.user_id	Number	Null	No	Null for system-level smart label or a valid `users.user_id` for ownership.

Example (Normal Labels)

$name = 'Read';
$slug = generateSlug($name);
// Attempt to create normal label$this->load->model('labels_model', 'labels');
$label = $this->labels->create(array('name' => $name, 'slug' => $slug));
// If label was createdif (isset($label->label_id)) {
// Good to go
}
// Some sort of validation errorelseif (isset($label['errors']) {
// Validation errors were found
}
// Some sort of database write error, check logselse {
// will return false
}

Example (Smart Labels - User Defined)

$url = 'http://amazon.com/gp/product';
$smart_info = getSmartLabelInfo($url);
// Attempt to create the smart label$this->load->model('labels_model', 'labels');
$label = $this->labels->create(array(
'domain' => $smart_info['domain'],
'path' => $smart_info['path'],
'smart_key' => $smart_info['key'],
'user_id' => $this->user_id
));
// If label was createdif (isset($label->label_id)) {
// Good to go
}

Example (Smart Labels - System Defined)

$url = 'http://youtube.com/watch';
$smart_info = getSmartLabelInfo($url);
// Attempt to create the smart label// Do NOT pass the user_id$this->load->model('labels_model', 'labels');
$label = $this->labels->create(array(
'domain' => $smart_info['domain'],
'path' => $smart_info['path'],
'smart_key' => $smart_info['key']
));
// If label was createdif (isset($label->label_id)) {
// Good to go
}

---

formatResults - Private

Since the labels table actually stores 3 different types of labels, we need to format the data a bit before it is returned. By formatting each row, it will set the type (smart or label) and if smart add some definitions for settings (smart_label_name, smart_label_slug and smart_label_id), each of those are inherited from the parent (normal label) the smart label applies when the rule is matched.

Arguments

Variable	Type	Default	Required	Description
$labels	object	N/A	Yes	The complete list of labels to be formatted and returned.

Example

$labels = $this->formatResults($labels);

---

readComplete - Public

Used to read all label data and return it in a nicely formatted structure. You can always use $this->labels->read to get the raw data from the table anytime you wish.

Arguments

Variable	Type	Default	Required	Description
$where	mixed	N/A	Yes	If numeric the where clause will be filled in with the id submitted and the correct column, otherwise it will just use the where clause you submitted.
$limit	integer	1	No	The max records to return.
$page	integer	1	No	The current page of records to return. Used as an offset in the LIMIT statement.
$start	integer	null	No	The start position to return records from.

Example

// Return all info for labels.label_id = 15// info will be accessible like $label->label_id since it's a single item$this->load->model('labels_model', 'labels');
$label = $this->labels->readComplete(15);
if (! isset($label->label_id)) {
// Good to go
}
else {
// Handle your errors
}
// Return all normal labels$this->load->model('labels_model', 'labels');
$labels = $this->labels->readComplete("labels.user_id IS NULL AND labels.smart_key IS NULL");
if ($labels !== false) {
foreach ($labelsas$label) {
// Doowutchalike
}
}
else {
// Handle your errors
}
// Return 5 system smart labels$this->load->model('labels_model', 'labels');
$labels = $this->labels->readComplete("labels.user_id IS NULL AND labels.smart_key IS NOT NULL", 5);
if ($labels !== false) {
foreach ($labelsas$label) {
// Doowutchalike
}
}
else {
// Handle your errors
}
// Return all user defined system smart labels$this->load->model('labels_model', 'labels');
$labels = $this->labels->readComplete("labels.user_id='56' AND labels.smart_key IS NOT NULL");
if ($labels !== false) {
foreach ($labelsas$label) {
// Doowutchalike
}
}
else {
// Handle your errors
}
