WordPress Outer Loop Cycles

    I am wondering how the WordPress “outer loop” works. By outer loop, I am referring to the core pages that run when WordPress is asked to deliver semantical content. The “WordPress loop is deep inside the outer loop. My question is not about the WordPress Loop.

    When the url to a post in WordPress is called, WordPress runs once to put the post with a template, build a web page, and send the page back to the requester. From what I can see, after that process is complete, WordPress runs again, not always, but always when the requested url is for a post, to be displayed on via the single.php template.

    Example, if you go to this post on my wordpress site, the outer loop runs twice, once for the requested post, then again for this post. Here is the data, showing timestamps and comments recorded by the pages as WordPress runs. The 2nd run data is in bold:

**** why doesn't WordPress stop here?  This time stamp is made at the bottom of index.php, when everything needed for the request has been run and is complete, yet the following time stamps show programs rana again.

  • There is no “outer loop” in WordPress. Can you replicate the problem using the default Twenty Fourteen theme with all plugins deactivated?

    Thread Starter wpforspeed

    (@wordpressforspeed)

    Yes, the results are the same with all plugins disabled.

    When WordPress is called to display a valid url, in runs the the following php scripts multiple times:

    • index.php
    • wp-blog-header.php
    • wp-includes/template-loader.php
    • page.php or other templates

    Steps to reproduce the result:

    1. Intall WordPress
    2. modify each php script listed above, to write a recored to a database database table when the script runs

    This produces a record of those pages running multiple times for each page request.

    I am wondering how that happens and why.

    The data shows the scripts running more than once, but I haven’t found where in the code the scripts are cycling like that. The code reads like WP should stop as soon as it gets to the end of the template it is using.

    I really appreciate your time looking at this. The cycling through php scripts does not happen if permalinks are set to default. When set to Post name, here is what happens.

    Browse to home page:
    WordPress Scripts Run followed by $_SERVER[“REQUEST_URI”]
    index.php /wordPressDemo/
    wp-blog-header.php /wordPressDemo/
    wp-load.php /wordPressDemo/
    template redirect: template-loader.php /wordPressDemo/
    template redirect: template-loader.php /wordPressDemo/
    page template: index.php /wordPressDemo/

    Browse to post, hit-logs-home-page: Series of scripts runs twice, changing $_SERVER[“REQUEST_URI”] while doing so.
    WordPress Scripts Run followed by $_SERVER[“REQUEST_URI”]
    index.php /wordPressDemo/hit-logs-home-page/
    wp-blog-header.php /wordPressDemo/hit-logs-home-page/
    wp-load.php /wordPressDemo/hit-logs-home-page/
    template redirect: template-loader.php /wordPressDemo/hit-logs-home-page/
    template redirect: template-loader.php /wordPressDemo/hit-logs-home-page/
    page template: single.php /wordPressDemo/hit-logs-home-page/
    index.php /wordPressDemo/hit-logs-post/
    wp-blog-header.php /wordPressDemo/hit-logs-post/
    wp-load.php /wordPressDemo/hit-logs-post/
    template redirect: template-loader.php /wordPressDemo/hit-logs-post/
    template redirect: template-loader.php /wordPressDemo/hit-logs-post/
    page template: single.php /wordPressDemo/hit-logs-post/
