问题 I know there are a lot of questions already asked on this but I am not able to get around with it. Please have a look: from a profile view when "update" button is pressed I want the user to be displayed with an editable form with values picked from database.

问题 I have a client that makes an AJAX call to categorize a URL. It will call myserver.php?url=facebook.com and the server would respond Social. There are no passwords involved and just a URL string for which the server would return a category.

问题 I'm trying to send array files using JS. My code: var formData = new FormData(); formData.append("files", files); $.ajax({ url: './upload.php', method: 'post', data: formData, processData: false, contentType: false, success: function(response) { alert('Files uploaded successfully.
