Generic PHP functions for data manipulation.

Functions

getAcfFieldsAsArray

Gets a bunch of specific ACF fields at once. Especially useful for option page settings, which only have a way to get one field at a time.

Parameters

$fields_names_arr (array|required): An array of the field names.

$option (boolean|optional): Set to true if the fields are from an options page.

Return Values

$data_arr (array): Data array keyed to the field names from the input array.

multidimensionalArrayMap

Like array_map, but for multidimensional arrays.

Parameters

$function The callback function to apply to each value of the array

$array The multi-dimensional array

Return Values

(array) The formatted array.

parseClassesAsArray

Take a string or array of classes, trim them and then return classes as an array.

Parameters

$classes (required): An flat array or comma-delimited string of classes.

Return Values

(boolean or array) If the formatted array is empty, returns false. Otherwise, returns array of classes.

printOnPresent

Like the proverbial weasel, this function pops out markup if data is present. It's a more efficient way of doing an if ( '' !== $data ) or if ( !empty( $data ) ) check: 3 lines for the price of one!

If you pass in a function name, the function will be executed. You can use anonymous functions too!

Usage

<?php CNP\Utility::printOnPresent( $string, '<h1 class="title">'. $string .'</h1>' ); ?>

Parameters

$string_or_array (required): The variable to check for data, which can be a string or an array. Objects are not supported.

$markup_or_function (required): What to do with the data if it is present. You can supply a string of markup, or call a function for more complex scenarios.

Return Values

(boolean or string) If the data check fails, printOnPresent returns false. If the data check is successful, then printOnPresent echoes the markup or function output from the $markup_or_function variable.
