Class: WP_Date_Query - X-Ref
Class for generating SQL clauses that filter a primary query according to date.| __construct( $date_query, $default_column = 'post_date' ) X-Ref |
| Constructor. Time-related parameters that normally require integer values ('year', 'month', 'week', 'dayofyear', 'day', 'dayofweek', 'dayofweek_iso', 'hour', 'minute', 'second') accept arrays of integers for some values of 'compare'. When 'compare' is 'IN' or 'NOT IN', arrays are accepted; when 'compare' is 'BETWEEN' or 'NOT BETWEEN', arrays of two valid values are required. See individual argument descriptions for accepted values. param: array $date_query { param: string $default_column Optional. Default column to query against. See WP_Date_Query::validate_column() |
| sanitize_query( $queries, $parent_query = null ) X-Ref |
| Recursive-friendly query sanitizer. Ensures that each query-level clause has a 'relation' key, and that each first-order clause contains all the necessary keys from `$defaults`. return: array Sanitized queries. param: array $queries param: array $parent_query |
| is_first_order_clause( $query ) X-Ref |
| Determines whether this is a first-order clause. Checks to see if the current clause has any time-related keys. If so, it's first-order. return: bool True if this is a first-order clause. param: array $query Query clause. |
| get_compare( $query ) X-Ref |
| Determines and validates what comparison operator to use. return: string The comparison operator. param: array $query A date query or a date subquery. |
| validate_date_values( $date_query = array() X-Ref |
| Validates the given date_query values and triggers errors if something is not valid. Note that date queries with invalid date ranges are allowed to continue (though of course no items will be found for impossible dates). This method only generates debug notices for these cases. return: bool True if all values in the query are valid, false if one or more fail. param: array $date_query The date_query array. |
| validate_column( $column ) X-Ref |
| Validates a column name parameter. Column names without a table prefix (like 'post_date') are checked against a list of allowed and known tables, and then, if found, have a table prefix (such as 'wp_posts.') prepended. Prefixed column names (such as 'wp_posts.post_date') bypass this allowed check, and are only sanitized to remove illegal characters. return: string A validated column name value. param: string $column The user-supplied column name. |
| get_sql() X-Ref |
| Generates WHERE clause to be appended to a main query. return: string MySQL WHERE clause. |
| get_sql_clauses() X-Ref |
| Generates SQL clauses to be appended to a main query. Called by the public WP_Date_Query::get_sql(), this method is abstracted out to maintain parity with the other Query classes. return: string[] { |
| get_sql_for_query( $query, $depth = 0 ) X-Ref |
| Generates SQL clauses for a single query array. If nested subqueries are found, this method recurses the tree to produce the properly nested SQL. return: array { param: array $query Query to parse. param: int $depth Optional. Number of tree levels deep we currently are. |
| get_sql_for_subquery( $query ) X-Ref |
| Turns a single date clause into pieces for a WHERE clause. A wrapper for get_sql_for_clause(), included here for backward compatibility while retaining the naming convention across Query classes. return: array { param: array $query Date query arguments. |
| get_sql_for_clause( $query, $parent_query ) X-Ref |
| Turns a first-order date query into SQL for a WHERE clause. return: array { param: array $query Date query clause. param: array $parent_query Parent query of the current date query. |
| build_value( $compare, $value ) X-Ref |
| Builds and validates a value string based on the comparison operator. return: string|false|int The value to be used in SQL or false on error. param: string $compare The compare operator to use. param: string|array $value The value. |
| build_mysql_datetime( $datetime, $default_to_max = false ) X-Ref |
| Builds a MySQL format date/time based on some query parameters. You can pass an array of values (year, month, etc.) with missing parameter values being defaulted to either the maximum or minimum values (controlled by the $default_to parameter). Alternatively you can pass a string that will be passed to date_create(). return: string|false A MySQL format date/time or false on failure. param: string|array $datetime An array of parameters or a strtotime() string. param: bool $default_to_max Whether to round up incomplete dates. Supported by values |
| build_time_query( $column, $compare, $hour = null, $minute = null, $second = null ) X-Ref |
| Builds a query string for comparing time values (hour, minute, second). If just hour, minute, or second is set than a normal comparison will be done. However if multiple values are passed, a pseudo-decimal time will be created in order to be able to accurately compare against. return: string|false A query part or false on failure. param: string $column The column to query against. Needs to be pre-validated! param: string $compare The comparison operator. Needs to be pre-validated! param: int|null $hour Optional. An hour value (0-23). param: int|null $minute Optional. A minute value (0-59). param: int|null $second Optional. A second value (0-59). |
| sanitize_relation( $relation ) X-Ref |
| Sanitizes a 'relation' operator. return: string Sanitized relation. Either 'AND' or 'OR'. param: string $relation Raw relation key from the query argument. |
