9 | /** |
---|
10 | * Retrieves an option value based on an option name. |
---|
11 | * |
---|
12 | * If the option does not exist, and a default value is not provided, |
---|
13 | * boolean false is returned. This could be used to check whether you need |
---|
14 | * to initialize an option during installation of a plugin, however that |
---|
15 | * can be done better by using add_option() which will not overwrite |
---|
16 | * existing options. |
---|
17 | * |
---|
18 | * Not initializing an option and using boolean `false` as a return value |
---|
19 | * is a bad practice as it triggers an additional database query. |
---|
20 | * |
---|
21 | * The type of the returned value can be different from the type that was passed |
---|
22 | * when saving or updating the option. If the option value was serialized, |
---|
23 | * then it will be unserialized when it is returned. In this case the type will |
---|
24 | * be the same. For example, storing a non-scalar value like an array will |
---|
25 | * return the same array. |
---|
26 | * |
---|
27 | * In most cases non-string scalar and null values will be converted and returned |
---|
28 | * as string equivalents. |
---|
29 | * |
---|
30 | * Exceptions: |
---|
31 | * 1. When the option has not been saved in the database, the `$default` value |
---|
32 | * is returned if provided. If not, boolean `false` is returned. |
---|
33 | * 2. When one of the Options API filters is used: {@see 'pre_option_{$option}'}, |
---|
34 | * {@see 'default_option_{$option}'}, or {@see 'option_{$option}'}, the returned |
---|
35 | * value may not match the expected type. |
---|
36 | * 3. When the option has just been saved in the database, and get_option() |
---|
37 | * is used right after, non-string scalar and null values are not converted to |
---|
38 | * string equivalents and the original type is returned. |
---|
39 | * |
---|
40 | * Examples: |
---|
41 | * |
---|
42 | * When adding options like this: `add_option( 'my_option_name', 'value' );` |
---|
43 | * and then retrieving them with `get_option( 'my_option_name' );`, the returned |
---|
44 | * values will be: |
---|
45 | * |
---|
46 | * `false` returns `string(0) ""` |
---|
47 | * `true` returns `string(1) "1"` |
---|
48 | * `0` returns `string(1) "0"` |
---|
49 | * `1` returns `string(1) "1"` |
---|
50 | * `'0'` returns `string(1) "0"` |
---|
51 | * `'1'` returns `string(1) "1"` |
---|
52 | * `null` returns `string(0) ""` |
---|
53 | * |
---|
54 | * When adding options with non-scalar values like |
---|
55 | * `add_option( 'my_array', array( false, 'str', null ) );`, the returned value |
---|
56 | * will be identical to the original as it is serialized before saving |
---|
57 | * it in the database: |
---|
58 | * |
---|
59 | * array(3) { |
---|
60 | * [0] => bool(false) |
---|
61 | * [1] => string(3) "str" |
---|
62 | * [2] => NULL |
---|
63 | * } |

73 | * Scalar and null values will be returned as strings as long as they originate |
---|

---|
75 | * boolean `false` is returned. |
