Purpose

The PHP code snippet you provided is designed to populate a searchbar dropdown with suggestions for users based on their search history, bookmarks, and tags.

Functionality

• The code first defines a function called truncate_and_bold() that formats the search suggestions by truncating the text to a specified length and bolding the portion that matches the user's input.
• It then checks if the user is logged in and retrieves their search query from a POST request.
• The code searches for history items, bookmarks, and tags in the database based on the user's input.
• It displays the suggestions in a table, each with an image and a clickable link to the corresponding search query.
• If no suggestions are found, the code either displays a message indicating that the user needs to press enter to search or that there are no suggestions available.

Features

• Autocomplete functionality based on user history, bookmarks, and tags.
• Formatting of suggestions to highlight the matched portion.
• Display of relevant images for each suggestion type.

Usage

This code is included in a PHP script that is triggered when a user enters text in the searchbar. It provides real-time suggestions based on their previous interactions with the platform.

Additional Notes

• The db_query() and db_return_row() functions are assumed to be defined in a library or script that handles database interactions.
• The truncate_and_bold() function should be further customized to suit the specific formatting requirements.
• The SEARCH variable should be properly sanitized to prevent SQL injection attacks.
