Jimmy Codeviewer

'codeview' series and 'articleloader' series display error messages on several situations, e.g., if you use these shortcodes with incorrect post IDs or Slugs, error messages emerge with error numbers. Each error number is assigned to know where the error occurs. If you want to see meaning of each error number, check jimmy-codeviewer.php and article-loader.php .

In WordPress, several characters automatically converted. This function may cause incorrect searching. It's in wp-includes/formatting.php. I'm trying to suppress these conversions. If you find a malfunction of searching process caused by any automatic converted character, please note it in the support forum of this plugin. Compatibility I. Themes On WordPress Team's "Twenty Seventeen", this Plugin works but you may need to customize "Twenty Seventeen" or this plugin to fit on display. Some themes such as "Twenty Seventeen" are having style flexibility between mobile devices and personal computers. Nowadays, rendering power of displays on both mobiles and personals are close to each other. Small displays can work as well as big displays by high density pixels. So I now recommend to trash flexibility between both. This gives us concentration of manpower to one layout in one site and grows quality of the site design. II. Web Browsers Firefox, Chrome, Opera, IE and Edge work on this plugin. Other browsers have not been tested. This plugin never guarantee to work SVG, JavaScript or other scripts in browsers. Even though you can load scripts using 'articleloader' series, these may not work properly. Security Notice Both 'codeview' series and 'articleloader' series do not support loading by post titles. Because post titles can not be guaranteed for unique naming, cross-site scripting attacks may occur by rewriting contents of "jArticles" on junior graded users (such as "jFellow"). Post ID and post slug have its unique naming. In extending or modifying this plugin, make sure NOT to use post titles for loading "jArticles". This plugin prohibit to load "jArticles" which don't be published by senior graded users (such as "Editor"). Senior graded users should pay attention to investigate SVGs, JavaScript and other scripts in "jArticles" for stopping any malicious activities before publishing "jArticles". In PHP, 0, '', "", '0', "0", array() and null means FALSE in boolean check, TRUE in empty check, empty() . Besides, "\0" stores null character in String. This means no empty. C language recognizes null character such as null terminator (recognized as End of String). This difference between PHP and C language is used by hackers. To prevent possible null byte injection, I added a method to erase every null character in every relevant shortcode. Every attribute in shortcodes seems like to be String type. Check shortcode_parse_atts in shortcodes.php in wp-includes. This function uses a set of shorcode attributes as a text. Therefore, for example, if you want some number as Integer type, you need cast the value to Integer type. PHP's integer cast uses atoi(), a C language function.

I'm thinking of making a GUI tool in this plugin. If you have some curious, please note it in the support forum of this plugin.
