Using PHP along with JavaScript, an auto-suggest input field can be implemented to provide real-time suggestions as the user types. This enhances the user experience by ensuring names are entered correctly.
To create the auto-suggest functionality, you can use jQuery or vanilla JavaScript. When a user types in the input field, an AJAX call can be made to a PHP script that queries the database for matching names.
The PHP script can return a list of suggestions in JSON format, which can then be used to populate a dropdown below the input field. This allows users to select names, ensuring accuracy.
Validation of the entered name is crucial. Once the user selects a name from the suggestions, you can pass the input to another PHP function that fetches the person's ID from the database.
