    <p>There is a lot going on here.</p> <ol> <li><p>Always us a integer as a primary key, example: id MEDIUMINT NOT NULL AUTO_INCREMENT. Then make it the primary key.</p></li> <li><p>you need to sanitize your input to the database using <code>mysql_real_escape_string()</code></p></li> <li><p>you need to concatenate your query, so it should look like this:</p> <p>mysql_query("UPDATE user SET username = '".mysql_real_escape_string($_POST[nusername])."'

    1. COI did what you proposed but it still doesn't do anything...Is there a possibility that there is problem with the html part, from which the php file takes the values? <form action="edit_user.php" method="post"> <p>Username<input type="text"name="nusername" size="40"></p> <p>Password<input type="password"name="npassword" size="40"></p> <p>Name<input type="text"name="nname" size="40"></p> <p>Surname<input type="text"name="nsurname" size="40"></p> <p>Role<input type="text"name="nrole" size="40"></p> <p><input type="submit></p> </form>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
