public Condition::condition($field, $value = NULL, $operator = '=')
Helper function: builds the most common conditional clauses.
This method can take a variable number of parameters. If called with two parameters, they are taken as $field and $value with $operator having a value of =.
Do not use this method to test for NULL values. Instead, use QueryConditionInterface::isNull() or QueryConditionInterface::isNotNull().
Drupal considers LIKE case insensitive and the following is often used to tell the database that case insensitive equivalence is desired:
db_select('users') ->condition('name', db_like($name), 'LIKE')
Use 'LIKE BINARY' instead of 'LIKE' for case sensitive queries.
Note: When using MySQL, the exact behavior also depends on the used collation. if the field is set to binary, then a LIKE condition will also be case sensitive and when a case insensitive collation is used, the = operator will also be case insensitive.
Parameters
$field: The name of the field to check. If you would like to add a more complex condition involving operators or functions, use where().
$value: The value to test the field against. In most cases, this is a scalar. For more complex options, it is an array. The meaning of each element in the array is dependent on the $operator.
$operator: The comparison operator, such as =, <, or >=. It also accepts more complex options such as IN, LIKE, LIKE BINARY, or BETWEEN. Defaults to =.
Return value
\Drupal\Core\Database\Query\ConditionInterface The called object.
