Support » Plugin: Post Snippets » php error invalid argument for foreach()

  • Resolved alevy5588


    doing some debug work, and came across this error:

    Invalid argument supplied for foreach() in /nas/content/staging/outputinc/wp-content/plugins/post-snippets/src/PostSnippets/WPEditor.php on line 189

    changing the line from:
    foreach ($snippets as $key => $snippet)


    foreach ((array) $snippets as $key => $snippet)

    removed the warning and seems to have not broken any functionality, but I wanted to run this by some peers on here to see if there is anything I’m missing with this edit that may become hazardous.
