|
||
*
|
||
* This is the most used object in the ProcessWire API.

* #pw-summary Enables loading and manipulation of Page objects, to and from the database.

|
||
* PROPERTIES
|
||
* ==========
|
||
* @property bool $cloning Whether or not a clone() operation is currently active #pw-internal
|
||
* @property bool $outputFormatting Current default output formatting mode. #pw-internal
|
||
* @property bool $autojoin Whether or not autojoin is allowed (typically true) #pw-internal
|
||
*
|
||
* HOOKABLE METHODS
|
||
* ================
|
||
* @method PageArray find($selectorString, array $options = array()) Find and return all pages matching the given selector string. Returns a PageArray. #pw-group-retrieval
|
||
* @method bool save(Page $page, $options = array()) Save any changes made to the given $page. Same as : $page->save() Returns true on success. #pw-group-manipulation
|
||
* @method bool saveField(Page $page, $field, array $options = array()) Save just the named field from $page. Same as: $page->save('field') #pw-group-manipulation
|
||
* @method bool trash(Page $page, $save = true) Move a page to the trash. If you have already set the parent to somewhere in the trash, then this method won't attempt to set it again. #pw-group-manipulation
|
||
* @method bool restore(Page $page, $save = true) Restore a trashed page to its original location. #pw-group-manipulation
|
||
* @method int|array emptyTrash(array $options = array()) Empty the trash and return number of pages deleted. #pw-group-manipulation
|
||
* @method bool delete(Page $page, $recursive = false, array $options = array()) Permanently delete a page and it's fields. Unlike trash(), pages deleted here are not restorable. If you attempt to delete a page with children, and don't specifically set the $recursive param to True, then this method will throw an exception. If a recursive delete fails for any reason, an exception will be thrown. #pw-group-manipulation
|
||
* @method Page|NullPage clone(Page $page, Page $parent = null, $recursive = true, $options = array()) Clone an entire page, it's assets and children and return it. #pw-group-manipulation
|
||
* @method Page|NullPage add($template, $parent, $name = '', array $values = array()) #pw-group-manipulation
|
||
* @method int sort(Page $page, $value = false) Set the “sort” value for given $page while adjusting siblings, or re-build sort for its children. #pw-group-manipulation
|
||
* @method setupNew(Page $page) Setup new page that does not yet exist by populating some fields to it. #pw-internal
|
||
* @method string setupPageName(Page $page, array $options = array()) Determine and populate a name for the given page. #pw-internal
|
||
* @method void insertBefore(Page $page, Page $beforePage) Insert one page as a sibling before another. #pw-advanced
|
||
* @method void insertAfter(Page $page, Page $afterPage) Insert one page as a sibling after another. #pw-advanced

|
||
* - `findOne` (bool): Apply optimizations for finding a single page (default=false).
|
||
* - `findAll` (bool): Find all pages with no exclusions, same as "include=all" option (default=false).
|
||
* - `findIDs` (bool|int): 1 to get array of page IDs, true to return verbose array, 2 to return verbose array with all cols in 3.0.153+. (default=false).
|
||
* - `getTotal` (bool): Whether to set returning PageArray's "total" property (default=true, except when findOne=true).
|
||
* - `loadPages` (bool): Whether to populate the returned PageArray with found pages (default=true).
|
||
* The only reason why you'd want to change this to false would be if you only needed the count details from

* - `caller` (string): Optional name of calling function, for debugging purposes, i.e. "pages.count" (default=blank).
|
||
* - `include` (string): Optional inclusion mode of 'hidden', 'unpublished' or 'all'. (default=none). Typically you would specify this
|
||
* directly in the selector string, so the option is mainly useful if your first argument is not a string.
|
||
* - `stopBeforeID` (int): Stop loading pages once page matching this ID is found (default=0).
|

/**
|
||
* Find pages and return raw data from them in a PHP array
|
||
*
|
||
* Note that the data returned from this method is raw and unformatted, directly
|
||
* as it exists in the database. In most cases you should use `$pages->find()` instead,
|
||
* but this method provides a convenient alternative for some cases.
|
||
*
|
||
* The `$selector` argument can be any page-finding selector that you would provide
|
||
* to a regular `$pages->find()` call. The most interesting stuff relates to the
|
||
* `$field` argument though, which is what the rest of this section looks at:
|
||
*
|
||
* If you omit the `$field` argument, it will return all data for the found pages in
|
||
* an array where the keys are the page IDs and the values are associative arrays
|
||
* containing all of each page raw field and property values indexed by name…
|
||
* `$a = $pages->findRaw("template=blog");` …but findRaw() is more useful for cases
|
||
* where you want to retrieve specific things without having to load the entire page
|
||
* (or its data). Below are a few examples of how you can do this.
|
||
*
|
||
* ~~~~~
|
||
* // If you provide a string (field name) for `$field`, then it will return an
|
||
* // array with the values of the `data` column of that field. The `$field` can
|
||
* // also be the name of a native pages table property like `id` or `name`.
|
||
* $a = $pages->findRaw("template=blog", "title");
|
||
*
|
||
* // The above would return an array of blog page titles indexed by page ID. If
|
||
* // you provide an array for `$field` then it will return an array for each page,
|
||
* // where each of those arrays is indexed by the field names you requested.
|
||
* $a = $pages->findRaw("template=blog", [ "title", "date" ]);
|
||
*
|
||
* // You may specify field name(s) like `field.subfield` to retrieve a specific
|
||
* // column/subfield. When it comes to Page references or Repeaters, the subfield
|
||
* // can also be the name of a field that exists on the Page reference or repeater.
|
||
* $a = $pages->findRaw("template=blog", [ "title", "categories.title" ]);
|
||
*
|
||
* // You can also use this format below to get multiple subfields from one field:
|
||
* $a = $pages->findRaw("template=blog", [ "title", "categories" => [ "id", "title" ] ]);
|
||
*
|
||
* // You can optionally rename fields in the returned value like this below, which
|
||
* // asks the 'title' field to have the name 'headline' in return value (3.0.176+):
|
||
* $a = $pages->findRaw("template=blog", [ "title" => "headline" ]);
|
||
*
|
||
* // You may specify wildcard field name(s) like `field.*` to return all columns
|
||
* // for `field`. This retrieves all columns from the field’s table. This is
|
||
* // especially useful with fields like Table or Combo that might have several
|
||
* // different columns:
|
||
* $a = $pages->findRaw("template=villa", "rates_table.*" );
|
||
*
|
||
* // If you prefer, you can specify the field name(s) in the selector (3.0.173+):
|
||
* $a = $pages->findRaw("template=blog, field=title");
|
||
* $a = $pages->findRaw("template=blog, field=title|categories.title");
|
||
*
|
||
* // Specify “objects=1” in selector to use objects rather than associative arrays
|
||
* // for pages and fields (3.0.174+):
|
||
* $a = $pages->findRaw("template=blog, field=title|categories.title, objects=1");
|
||
*
|
||
* // Specify “entities=1” to entity encode all string values:
|
||
* $a = $pages->findRaw("template=blog, field=title|summary, entities=1");
|
||
*
|

* // Specify “entities=field” or “entities=field1|field2” to entity encode just
|

||
* - `autojoin` (boolean): Allow use of autojoin option? (default=true)
|
||
* - `joinFields` (array): Autojoin the field names specified in this array, regardless of field settings (requires autojoin=true). (default=empty)
|
||
* - `joinSortfield` (boolean): Whether the 'sortfield' property will be joined to the page. (default=true)
|
||
* - `findTemplates` (boolean): Determine which templates will be used (when no template specified) for more specific autojoins. (default=true)
|
||
* - `pageClass` (string): Class to instantiate Page objects with. Leave blank to determine from template. (default=auto-detect)

* - Specify false for `getNumChildren` for potential speed optimization when you know for certain pages will not have children.
|
||
* - Specify false for `autojoin` for potential speed optimization in certain scenarios (can also be a bottleneck, so be sure to test).
|
||
* - Specify false for `joinSortfield` for potential speed optimization when you know the Page will not have children or won't need to know the order.

* - Specify false for `findTemplates` so this method doesn't have to look them up. Potential speed optimization if you have few autojoin fields globally.
