Introduction

This article discusses the process of creating a simple web application using the Open AI API to generate news articles. The tutorial provides step-by-step instructions on how to Create the interface, extract news headlines, and generate article content with images. By following this tutorial, You will learn how to utilize the Open AI API in a web application and create dynamic news articles Based on user-selected categories.

Demo of Creating a Web Application with Open AI API

In this tutorial, we will start by creating a demo web application that allows users to select a news category from a dropdown menu. Upon submitting their selection, the application will retrieve news headlines corresponding to the chosen category. The user can then click on a specific headline to view the full article, complete with content and images.

Code Explanation

To understand how the web application works, let's dive into the code and explain the different components involved. We will explore three PHP files: newsmaker.psp, getheadlines.php, and getarticle.php. Each file serves a specific purpose in the application's functionality.

Creating the Interface (newsmaker.psp)

The newsmaker.psp file is responsible for creating the user interface of the web application. It contains HTML and JavaScript code that sets up a dropdown menu for selecting news categories and a submit button. When the user clicks the submit button, the value of the selected category is passed to getheadlines.php using an Ajax post method.

Extracting News Headlines (getheadlines.php)

The getheadlines.php file utilizes the Open AI API to retrieve news headlines for a specific category. It makes use of a curl code to send a request to the Open AI completions endpoint. The code includes parameters such as the prompt, model, and maximum token. The response from the API call is manipulated and displayed on the web application.

Generating Article Content (getarticle.php)

The getarticle.php file is responsible for generating the content and images associated with a selected news headline. Similar to getheadlines.php, it uses the Open AI API to retrieve the content. The curl code is used twice, once for generating the text content and the Second time for generating the images. The base64 encoded images are converted into HTML format for display on the web application.

Understanding the Open AI API

Before delving into the code, it is essential to understand the parameters and model selection for the Open AI API. The two crucial fields to note are the model and the prompt. The model used in this tutorial is text DaVinci 003, which is known for its text generation capabilities. The prompt is the input text provided to the API, and the model generates a text completion based on this prompt.

Creating the Interface (newsmaker.psp)

Let's now focus on the newsmaker.psp file, which is responsible for creating the interface of our web application. It contains HTML and JavaScript code to set up the dropdown menu, handle button actions, and display the output.

To create the dropdown menu, we use the <select> tag in HTML and populate it with various news categories. Additionally, we include a submit button so that users can submit their category selection.

To handle the button action, we define two JavaScript functions: getheadlines() and getarticle(). The getheadlines() function sends an Ajax post request to the getheadlines.php file, passing the selected category value. The response from the API call is displayed inside a <div> on the newsmaker.psp page.

Similarly, the getarticle() function passes the selected news headline value to the getarticle.php file using the post method. The response from the API call is also displayed inside a <div> on the newsmaker.psp page.

Extracting News Headlines (getheadlines.php)

Moving on to the getheadlines.php file, it serves the purpose of extracting news headlines for a specific category using the Open AI API.

The file utilizes a curl code to make a request to the Open AI completions endpoint. The parameters for the API call are set up in an array and converted to JSON format using the json_encode() method. Some important fields in the parameter array are prompt, model, and maximum token. The prompt value is crucial as it determines the specific news category to retrieve headlines for.

Additionally, the API key is passed in the authorization header of the curl code. The response from the API call is stored in the $response variable, and the code below it manipulates and formats the output to meet our desired requirements. The headlines are displayed on the newsmaker.psp page.

Generating Article Content (getarticle.php)

The getarticle.php file is responsible for generating the content and images associated with a selected news headline. It also utilizes the Open AI API to achieve this functionality.

Similar to getheadlines.php, the file uses a curl code to make a request to the Open AI API. It retrieves the article text and images separately. The parameters for the API call, such as completion and images generation, are set up in the curl code's endpoint URL. The prompt value remains the same as in the previous file, ensuring consistency.

The output of the second curl code, which retrieves the images, is in base64-encoded form. To display the images on the web application, we convert the base64-encoded output into HTML format using a custom function named getlogo().

Conclusion

In this tutorial, we explored the process of creating a web application that utilizes the Open AI API to generate news articles. We discussed the code involved in creating the interface, extracting news headlines, and generating article content with images. By following this guide, you can build a dynamic web application that provides users with personalized news articles based on their selected categories.

Pros and Cons

Pros:

• The web application allows users to retrieve news articles with ease and convenience.
• The Open AI API provides accurate and Timely headlines based on the selected category.
• The addition of images enhances the visual appeal and user experience of the news articles.

Cons:

• The complexity of the code and utilization of multiple files may pose challenges for beginners.
• Continuous maintenance and updates may be required to ensure compatibility with future API changes.
• The reliance on the Open AI API subjects the web application to any issues or limitations experienced by the API itself.

Frequently Asked Questions (FAQ)

Q: Can I customize the dropdown menu to include additional news categories? A: Yes, you can easily modify the dropdown menu in the newsmaker.psp file by adding additional options for news categories.

Q: How do I change the length of the generated news articles? A: The length of the generated articles can be adjusted by changing the value of the Max token variable in the code. Increasing the value will result in longer articles, while decreasing it will generate shorter articles.

Q: Is it possible to add more than two images to a news article? A: Yes, you can modify the code in the getarticle.php file to generate a desired number of images for each news article. The n variable determines the number of images to be generated.

Q: Can I use a different model for text generation instead of text DaVinci 003? A: Yes, you can experiment with different models to achieve different text generation capabilities. However, text DaVinci 003 is known to be an excellent model for text generation tasks.

Q: How often do the news headlines get updated in the web application? A: The news headlines are retrieved in real-time from the Open AI API, ensuring that the web application consistently provides the latest headlines for each selected category.
