oik_lib_check_libs() – Check the existence of the available libraries for the given plugin

You appear to be a bot. Output may be restricted

Description

A plugin may say that it offers a set of libraries but that doesn't guarantee that the library file exists. This routine checks for the existence of the source file before it's added to the array of libraries. It doesn't check for the dependencies.

Usage

$array = oik_lib_check_libs( $libraries, $libs, $plugin );

Parameters

$libraries

( array ) required – array of registered libraries

$libs

( array ) required – array of libraries to add in form "library" => "dependencies"

$plugin

( string ) required – plugin slug

Returns

Source

function oik_lib_check_libs( $libraries, $libs, $plugin ) {
  $lib_args = array();
  foreach ( $libs as $library => $depends ) {
    $src = oik_path( "libs/$library.php", $plugin ); 
    if ( file_exists( $src ) ) {
      $lib_args['library'] = $library;
      $lib_args['src'] = $src;
      $lib_args['deps'] = $depends;
      $lib = new OIK_lib( $lib_args );
      $libraries[] = $lib;
    } else {
      bw_log( $src, "$plugin does not deliver $library file in $src", false );
    }
  }
  return( $libraries );
