SetRequiredKeywords

CAdvBanner::SetRequiredKeywords(
    mixed keywords,
    varchar(255) TYPE_SID=""
);

The method assigns a set of required keywords to a given page. If all of the banner or contract keywords are found within a page, the probability of show of the banner is higher. In case no banner satisfying the keyword set can be found, a banner for the show is selected from those without any keywords. Non-static method.

Parameters

Parameter	Description
keywords	Keywords. See Notes for description of information types that can be passed in this parameter.
TYPE_SID	Type identifier. Describes the advertisement type to which the keywords are to be assigned. Leave this parameter empty to assign keywords to all types.

Example

The following is an example of using the method in the real page.

<?
require_once($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/include/prolog_before.php");
if (CModule::IncludeModule("advertising"))
{
    // required exact match keywords 
    $arrKeywords = array();
    $arrKeywords[] = array("EXACT_MATCH" => "Y", "KEYWORD" => "GeForce");
    $arrKeywords[] = array("EXACT_MATCH" => "Y", "KEYWORD" => "video");
    CAdvBanner::SetRequiredKeywords($arrKeywords, "LEFT");

     // required fuzzy match keywords
    CAdvBanner::SetRequiredKeywords(array("Ford", "BMW", "Lada"), "RIGHT");
}

$APPLICATION->SetTitle("Title");
require_once($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/include/prolog_after.php");

// page body
require_once($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/include/epilog.php");
?>

Global use in prolog_after.php:

<?
if (CModule::IncludeModule("advertising"))
{
    CAdvBanner::SetRequiredKeywords($APPLICATION->GetProperty("keywords"));
}

?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<body>
...

If a page contains keywords, the following two scenarios are possible.

No banners matching the keyword list are found. In this case, banners with an empty list of keywords are displayed according to their priority.
More than one matching banners are found. In this case, a banner is selected that has the highest priority with respect to the priority of its contract.

Please remember that a full list of banner keywords is comprised by both banner keywords and keywords of a contract to which the banner is attached.

Notes

Structures that can be passed in the keywords parameter include the following.

Array with arrays with keys:

EXACT_MATCH - denotes the match type: exact match (Y) or occurrence (N).
KEYWORDS - the keyword.

Sample

Array
(
    [0] => Array
    (
        [EXACT_MATCH] => Y
        [KEYWORD] => GeForce
    )

    [1] => Array
    (
        [EXACT_MATCH] => Y
        [KEYWORD] => Radeon
    )
)

Array of keywords.
Sample
```
Array
(
    [0] => GeForce
    [1] => Radion
    [2] => Sony
)
```
In this case, the fuzzy match algorithm is applied for searching for matching keywords; search includes all of the required keywords.
Comma-separated list of keywords.
Sample
```
"GeForce, Radion, Sony"
```
In this case, the fuzzy match algorithm is also applied for searching for matching keywords.
