Populating a dynamic drop down menu from a MySQL database
Posted on February 13th, 2009 6 comments
This PHP code snippet retrieves the data in a specific column of each row in a MySQL table. The retrieved data is echoed to the DOM and displayed as options of a drop down menu. The options of the drop down menu are dynamic, as they will change automatically every time the information in the database is modified.This is the code:
<? // Make MySQL Connection mysql_connect("localhost", "admin", "pass") or die(mysql_error()); mysql_select_db("database") or die(mysql_error()); $sql = "SELECT column_name FROM table"; // Echo echo "<SELECT name="selectmenu">"; $result = mysql_query($sql); // Loop to get and echo the results as options while ($row = mysql_fetch_assoc($result)) { echo '<option value="'.$row["column_name"].'">' .$row["column_name"].'</option>'; } echo "</SELECT>"; ?>With this code your drop down menu should contain as options the data in column_name for each row.
An explanation on the mysql_fetch_assoc function can be found here.
