The code defines a PHP function petstory_upload_img
that takes an array $data
as input. The function does the following:
- Gets the path to the WordPress uploads directory using the
wp_upload_dir()
function. - Converts the forward slashes in the upload directory path to the appropriate DIRECTORY_SEPARATOR for the server OS.
- Extracts the base64-encoded image data from the
$data['src']
string and replaces any spaces with plus signs. - Decodes the base64-encoded image data into binary data.
- Generates a unique filename for the image by hashing the current time and the original file name from the
$data
array. - Saves the decoded image data as a file in the WordPress uploads directory using the generated hashed filename.
- Creates an attachment object with metadata about the uploaded image, including the MIME type, title, content, status, and URL.
- Inserts the attachment into the WordPress database using the
wp_insert_attachment()
function and returns the attachment's ID.
Overall, this function takes image data from a client-side form submission, saves it to the WordPress uploads directory, creates an attachment post in the WordPress database, and returns the ID of the new attachment.
