Function and usage of get_options() in wordpress


Answers ( 1 )


    The get_options() function in WordPress is designed to retrieve multiple options in an efficient manner. Here's a detailed explanation of its function and usage:

    Function: get_options( array $options ): array


    This function is used to retrieve multiple options/settings from the WordPress database.


    • Efficiency: One of the key features of get_options() is its efficiency. It loads options as necessary to minimize the number of database queries. This means that if some options are already loaded, it won't make additional unnecessary queries. It aims to use a single database query at most to fetch the required options.
    • Bulk Retrieval: Unlike get_option(), which retrieves a single option, get_options() is used for fetching multiple options in one go.


    • $options (array, required): This parameter takes an array of option names that you want to retrieve. These option names are typically the keys used in the wp_options table of the WordPress database.

    Return Value

    • Return Type: array
    • Description: The function returns an associative array where the keys are the option names (as specified in the $options array) and the values are the corresponding option values from the database.

    Sample Usage

    // Example: Retrieving multiple WordPress settings
    $options_to_get = array('blogname', 'blogdescription', 'admin_email');
    $retrieved_options = get_options($options_to_get);
    // Displaying the retrieved options
    foreach ($retrieved_options as $option_name => $option_value) {
        echo 'Option: ' . $option_name . ' - Value: ' . $option_value . '<br>';

    In this example:

    1. Array of Options: An array $options_to_get is defined, containing the names of the options we want to retrieve: 'blogname', 'blogdescription', and 'admin_email'.
    2. Retrieving Options: get_options() is called with this array, and the returned value is stored in $retrieved_options.
    3. Output: A loop is used to iterate over the returned associative array, displaying each option's name and its corresponding value.

    This function is particularly useful in scenarios where you need to fetch multiple settings or configurations without making multiple calls to the database, thus optimizing performance.
