* Page is the class used by all instantiated pages and it provides functionality for:
|
||
*
|
||
* 1. Providing get/set access to the Page's properties
|
||
* 2. Accessing the related hierarchy of pages (i.e. parents, children, sibling pages)

* #pw-summary-languages Multi-language methods require these core modules: `LanguageSupport`, `LanguageSupportFields`, `LanguageSupportPageNames`.
|
||
* #pw-summary-system Most system properties directly correspond to columns in the `pages` database table.
|
||
* #pw-summary-previous Provides access to the previously set runtime value of some Page properties.

* The `$page` API variable represents the current page being viewed. However, the documentation
|
||
* here also applies to all Page objects that you may work with in the API. We use `$page` as the most common example
|
||
* throughout the documentation, but you can substitute that with any variable name representing a Page.

|
||
* of code. Use this when looking for a useful shortcut and this one fits your need, otherwise
|
||
* use a regular PHP if() statement.
|
||
*
|
||
* This function is primarily intended for conditionally outputting some formatted string value or
|
||
* markup, however its use is not limited to that, as you can specify whatever you’d like for the
|
||
* $yes and $no conditions. The examples section best describes potential usages of this method,
|
||
* so I recommend looking at those before reading all the details of this method.
|
||
*
|
||
* Note that the logic is a little bit smarter for PW than a regular PHP if() statement in these ways:
|
||
*
|
||
* - If value resolves to any kind of *empty* `WireArray` (like a `PageArray`) the NO condition is used.
|
||
* If the WireArray is populated with at least one item then the YES condition is used. So this if()
|
||
* method (unlike PHP if) requires that not only is the value present, but it is also populated.
|
||
*
|
||
* - If value resolves to a `NullPage` the NO condition is used.
|
||
*
|
||
* The `$key` argument may be any of the following:
|
||
*
|
||
* - A field name, in which case we will use the value of that field on this page. If the value is
|
||
* empty the NO condition will be used, otherwise the YES condition will be used. You can use any
|
||
* format for the field name that the `Page::get()` method accepts, so subfields and OR field
|
||
* statements are also okay, i.e. `categories.count`, `field1|field2|field3', etc.
|
||
*
|
||
* - A selector string that must match this page in order to return the YES condition. If it does not
|
||
* match then the NO condition will be used.
|
||
*
|
||
* - A boolean, integer, digit string or PHP array. If considered empty by PHP it will return the NO
|
||
* condition, otherwise it will return the YES condition.
|
||
*
|
||
* The `$yes` and `$no` arguments (the conditional actions) may be any of the following:
|
||
*
|
||
* - Any string value that you’d like (HTML markup is fine too).
|
||
*
|
||
* - A field name that is present on this page, or optionally the word “value” to refer to the field
|
||
* specified in the `$key` argument. Either way, makes this method return the actual field value as it
|
||
* exists on the page, rather than a string/markup version of it. Note that if this word (“value”) is
|
||
* used for the argument then of course the `$key` argument must be a field name (not a selector string).
|
||
*
|
||
* - Any callable inline function that returns the value you want this function to return.
|
||
*
|
||
* - A string containing one or more `{field}` placeholders, where you replace “field” with a field name.
|
||
* These are in turn populated by the `Page::getMarkup()` method. You can also use `{field.subfield}`
|
||
* and `{field1|field2|field3}` type placeholder strings.
|
||
*
|
||
* - A string containing `{val}` or `{value}` where they will be replaced with the markup value of the
|
||
* field name given in the $key argument.
|
||
*
|
||
* - If you omit the `$no` argument an empty string is assumed.
|
||
*
|
||
* - If you omit both the `$yes` and `$no` arguments, then boolean is assumed (true for yes, false for no),
|
||
* which makes this method likewise return a boolean. The only real reason to do this would be to take
|
||
* advantage of the method’s slightly different behavior than regular PHP if() statements (i.e. treating
|
||
* empty WireArray or NullPage objects as false conditions).

|
||
*
|
||
* You can specify an `$options` argument to this method with any of the following:
|
||
*
|
||
* - `pageNum` (int|string|bool): Specify pagination number, "+" for next pagination, "-" for previous pagination,
|
||
* or boolean true (3.0.155+) for current.
|
||
* - `urlSegmentStr` (string|bool): Specify a URL segment string to append, or true (3.0.155+) for current.
|
||
* - `urlSegments` (array|bool): Specify array of URL segments to append (may be used instead of urlSegmentStr),
|
||
* or boolean true (3.0.155+) for current. Specify associative array to use keys and values in order (3.0.155+).
|
||
* - `data` (array): Array of key=value variables to form a query string.
|
||
* - `http` (bool): Specify true to make URL include scheme and hostname (default=false).
|
||
* - `language` (Language): Specify Language object to return URL in that Language.
|
||
* - `host` (string): Force hostname to use, i.e. 'world.com' or 'hello.world.com'. The 'http' option is implied. (3.0.178+)
|
||
* - `scheme` (string): Like http option, makes URL have scheme+hostname, but you specify scheme here, i.e. 'https' (3.0.178+)
|
||
* Note that if you specify scheme of 'https' and $config->noHTTPS is true, the 'http' scheme will still be used.
|
||
*
|
||
* You can also specify any of the following for `$options` as shortcuts:
|
||
*
|
||
* - If you specify an `int` for options it is assumed to be the `pageNum` option.
|
||
* - If you specify `+` or `-` for options it is assumed to be the `pageNum` “next/previous pagination” option.
|
||
* - If you specify any other `string` for options it is assumed to be the `urlSegmentStr` option.
|
||
* - If you specify a `boolean` (true) for options it is assumed to be the `http` option.
|
||
*
|
||
* Please also note regarding `$options`:
|
||
*
|
||
* - This method honors template slash settings for page, URL segments and page numbers.
|
||
* - Any passed in URL segments are automatically sanitized with `Sanitizer::pageNameUTF8()`.
|
||
* - If using the `pageNum` or URL segment options please also make sure these are enabled on the page’s template.
|
||
* - The query string generated by any `data` variables is entity encoded when output formatting is on.
|
||
* - The `language` option requires that the `LanguageSupportPageNames` module is installed.
|
||
* - The prefix for page numbers honors `$config->pageNumUrlPrefix` and multi-language prefixes as well.
