If you used the jQuery Dialogify plug-in to create a modal pop-up dialog box with your PHP web application. In this application, you then have to perform all data update operations. For this reason, this release will help you integrate the jQuery Dialogify plugin to update or edit the data operation using PHP with Ajax. In the previous part we saw how we can use the jquery Dialogify plugin to insert or add data to MySQL data using PHP with Ajax. We used the jlogue-based Dialogify library for the popup modal on the website. Because it's very easy to use and it's light and simple. To create a modal dialog box, we don't need to write HTML when using this plugin. In this way, users can write callback function calls at any time.
Here we would like to update or edit existing MySQL data using a PHP script with Ajax. Load existing data into the modal dialog box. If you used this add-in, you must create a separate HTML form file to load the data into the form. To update or edit data, we first want to retrieve the existing data from the database by sending an Ajax request to PHP. Once the json data has been received, we would first like to save it in the local memory of the browser using the localStorage object, which stores the data without an expiry date.
After all data has been saved in the local memory of the browser using the localStorage.setItem () method. With this method we can save data in the local memory of the browser. After we have saved all the data, we have to switch to a separate file in which we have created HTML form fields. In this file, we need to use the localStorage.getItem () method to look for data from the browser's local storage. With this method we can retrieve data from the local memory of the browser and store it in the local variable. After we have searched all the data, we need to assign this data to the HTML form fields using the JQuery code. Finally, we have to use the new Dialogify () method and create a popup dialog with separate file form fields with filler data. If we then click the "Refresh" button, a modal dialog box with the data of the filling out form is displayed. Finally, we have to activate the Ajax request when it is used. Click the Edit button that sends the Ajax request to the PHP script to update the data. All of this process code can be found below.
