How Do I Upload an Image in WordPress Programmatically?

One way to upload an image in WordPress is to use the wp_upload_image() function. This function takes two arguments: the file name of the image to be uploaded and the size of the image to be uploaded.

The function returns a reference to the uploaded image object.

To use the wp_upload_image() function, you first need to generate an upload object. To do this, you first need to create an instance of the Uploadable class.

The following code example shows how to do this.

$upload = new Uploadable();

After you have created an upload object, you can use the wp_upload_image() function to upload the image. The following code example shows how to do this.

$upload->add_file($file_name, $size);

The wp_upload_image() function will return a reference to the uploaded image object. You can then use the image object to do whatever you want with it.

The following code example shows how to display the uploaded image in a WordPress post.

echo $upload->get_file_name();

If you want to delete the uploaded image, you can use the wp_delete_image() function.

$upload->delete();

The wp_upload_image() function is a convenient way to upload images in WordPress. However, there are a few things to keep in mind. First, you need to make sure that you have properly set up your WordPress site so that images can be uploaded.

Second, you need to be aware of the size limitations of the wp_upload_image() function. Finally, be sure to use the wp_delete_image() function to delete uploaded images if you want to.
