Extended Search Plugin

Extended Search is a custom WordPress plugin designed to enhance the default WordPress search functionality by extending it to query a custom database table. The plugin allows you to search specific fields in the custom table while removing the default WordPress search behavior that queries the posts table.

Features

• Extends the WordPress search functionality to join a custom database table.
• Searches specific fields within the custom table.
• Disables the default WordPress search that targets the posts table.

Requirements

• WordPress 5.2 or higher
• PHP 7.2 or higher

Installation

1. Download the plugin zip file.
2. Navigate to the Plugins section in your WordPress dashboard.
3. Click on Add New and then Upload Plugin.
4. Choose the downloaded zip file and click Install Now.
5. After the installation is complete, click Activate to enable the plugin.

Usage

Once activated, the Extended Search plugin automatically modifies the default WordPress search behavior. It:

• Joins the search query with a specified custom database table.
• Searches for terms in the custom table's defined fields.
• Excludes the posts table from being searched, focusing entirely on the custom table.

Example

If you have a custom table named wp_ttdn_meta_customtable with fields like mst, ten_cong_ty, etc., the plugin will modify the search query to search within these fields.

Customization

To customize the plugin behavior, such as specifying which custom table and fields to search, you can modify the plugin settings in the class-search-modify file.
