PHP Search Filters
PHP search filters use LIKE queries for database searches.
Introduction to PHP Search Filters
PHP search filters are essential for querying databases to find specific information based on user input. They allow you to create more dynamic and interactive web applications. This tutorial will guide you on how to implement a search filter using PHP and SQL's LIKE clause to efficiently search through database records.
Setting Up the Database
Before implementing the search filter, you need a database table to search through. For this example, we'll use a simple table called products with the following structure:
Connecting to the Database
First, establish a connection to your database using PHP's PDO or MySQLi. Here, we'll use PDO for its ease and flexibility:
Implementing the Search Filter
Now, let's create the PHP script to handle the search input from the user and query the database using the LIKE operator. This operator is used to search for a specified pattern in a column.
Creating the HTML Form
To allow users to input their search queries, you need an HTML form. This form will send the search term to the PHP script using the POST method.
Displaying the Results
Finally, let's display the results of the search query. The following code iterates over the results array and outputs the product details.
