And we have also set the width and height of those images. In this example, you can see the data in the table format for proper view. In this example, we have created a folder whose name is all_images.

Note: You also have to create a folder for storing images. Try this: from mysqlrealescapestring (POST from) to mysqlrealescapestring (POST to) message mysqlrealescapestring (POST message) query 'SELECT FROM Users WHERE username from LIMIT 1' result mysqlquery (query) or die (mysqlerror ()) while (row. The utility can help you to simulate the database production environment and allows you to populate several MySQL database tables with test data simultaneously, define tables and fields for generating data, set value ranges, generate MySQL char. You can see the above example there are fetched data with the images. EMS Data Generator for MySQL is an impressive tool for generating test data to MySQL database tables with the possibility to save and edit scripts. You must have to write enctype="multipart/form-data" property in the form tag for why because we insert file/image into the database.Īfter storing data, we are fetching those data at a time using mysqli_fetch_array() function from the database. In this file, we are using a table for displaying records and images in the proper format. The index.php file is using for both purposes, which are inserting images and displaying images from the database. Here, we are storing an image into the database and retrieve an image from the database into the table format.

Then, the user submits your form, another question is randomly selected, and that's the question you are using to check the answer, instead of the question you asked to the user.Step 2: Store and Retrieve image from Database When you ask your question to the user, a question is randomly selected from the database. $result_get_question = mysqli_query($conn,$get_question)

UPDATE $get_question = "SELECT * from questions_table where id = $begin_id" to a list of values that are not stored in a database table and cannot be retrieved by a query. Store data in the database using INSERT INTO query and retrieve. To create a lookup editor bound to a custom value list i.e. However, something is wrong : no matter what answer the user selects, it is always the WRONG answer!!įor some reason, selecting random questions from the database has messed up the " Correct answer / Wrong answer" logic in my PHP code. It is simple to upload image in PHP MySQL database and display image with example and code. This works, as far as selecting random questions goes.

Express Tutorial Part 3: Using a Database PHPRunner is php code generator and php. Here is the code I used (the simplest one) : SELECT * from questions_table order by rand() limit 1 To show the values in the input fields after the user hits the submit. This was easy, especially as there are so many online tutorials on how this is done. Now, I decided to make it even more "efficient" instead of selecting questions sequentially, I decided to simply modify my PHP-SELECT statement, to select questions RANDOMLY. $row_get_question = mysqli_fetch_array($result_get_question) $result_get_question = mysqli_query($conn, $get_question) $get_question = "SELECT * from questions_table where id = $begin_id" (Meaning, the user never sees the same question twice!) Instead, he begins from the NEXT question in the list. It is possible to customize the html display and you can. So that : the next time the user logs on, and plays the quiz, he does not begin from Question-1. This program is also a management tool that you can use to add, edit or delete your database records. Meaning, it records the LAST question the user answered (whether wrongly or correctly). Each time the user answers a question, this column is updated with that question's "ID". (3) To make it more interesting, I added an extra column to the database (begin_id), which has a default value of "1", when a user registers as a player on my quiz-website. So, when the user starts playing, he begins with Question 1, then Question 2, etc, etc. (2) Then, my PHP code was designed to pick questions, one by one, in SEQUENTIAL order (using the ID as reference). The table has the following columns : ID (primary key)ĬORRECT (the correct answer - which is one of the above A1 to A4) (1) created a database table, which contains 1500 questions.

If he picks the wrong one, the quiz comes to an end.Īt first, I designed the quiz as follows : If the player picks the correct one, he proceeds to the next question The quiz is designed to display one question at a time the questions are multiple-choice (each question has 4 possible answers) I am building a simple quiz program, using PHP and MYSQL.
