Describes how to prevent PbootCms from automatically extracting pictures from articles as thumbnails

PbootCms is a content management system based on PHP, which is used to quickly build websites. It has the function of automatically extracting the first picture in an article as a thumbnail, but sometimes this function is not applicable to all situations. This article will introduce how to prevent PbootCms from automatically extracting pictures in articles as thumbnails.

1. Open IDE tools, such as VScode or Sublime.
2. Use "When there is no thumbnail" as the keyword to search the entire project, and you can find two files with three codes.
3. Open the searched code location and modify it in the following code section:

    //When there is no thumbnail, automatically extract the first image of the article as a thumbnail if (!  ico && preg_match('/<img\s+.*? src=\s? [\'|\"](.*?(\.gif|\.jpg|\.png|\.jpeg))[\'|\"].*? [\/]?>/ i', decode_string(content), srcs) && isset(srcs[1])) { $ico = $srcs[1]; }

4. Comment out the three lines of code beginning with if in the above code, that is, add a double slash (//) at the beginning of the three lines.
5. After all three comments are made, save the modified file.
6. In this way, the function of PbootCms to automatically extract pictures from articles as thumbnails is successfully disabled.
