Problem:

I am having an issue where the Toolset plugin shows a notice stating it cannot connect to toolset.com, likely due to network or security settings blocking outgoing communication.

Solution:

I should ensure I am logged in to toolset.com, then go to WordPress Dashboard > Plugins > Add New > Commercial (Tab) to unregister and re-register Toolset using the provided steps, and if the issue persists, contact my hosting provider to whitelist api.toolset.com and cloudfront.net.

Problem:

I'm encountering a PHP notice: "Only variables should be passed by reference" due to code in my check_filetype.php file. The code, created years ago, is producing this warning in the logs.

Solution:

This warning occurs because PHP prefers variables over direct function calls in end() statements. To resolve this, assign the results of explode() functions to variables before using end(). Here’s an updated version of your code:

<?php
/**
 * Check if the user uploaded job CPT file is a pdf.
 */
 
toolset_snippet_security_check() or die( 'Direct access is not allowed' );
 
add_shortcode( 'check_filetype', 'func_check_file_type' );
function func_check_file_type( $atts ) {

    $atts = shortcode_atts( array(
        'url' => '',
    ), $atts );

    $url_parts = explode( '/', $atts['url'] );
    $file_name = end( $url_parts );
    $file_extension = explode( '.', $file_name );

    return end( $file_extension );
}

Explanation of Changes:

- Saved the results of explode() into $url_parts and $file_extension.
- Applied end() on these variables rather than directly on the function calls.
