Body
<p>I'm working on a form in which the user makes a few selections, and then each selected item's name needs to go into a table in a db. The user's name can go with each item as an identifier for the user's selections. The number of selections, and the names of the selections will change but the two fields in the database remain constant. My problem is that on insert, I get an error that there is no column with the name specified in the VALUE I'm sending. Its tripped me all up....can't figure out why. Thanks a lot for any help or advice. </p> <p>Full code:</p> <pre><code><?php $db = mysql_connect('localhost', 'root', 'root') or die(mysql_error()); mysql_select_db('reflex') or die(mysql_error()); $name_array = array('harp1','harp2','harp3'); if (isset($_POST['interests'])) { $interests_str = implode(" ", $_POST['interests']);// converts $_POST interests into a string $interests_array = explode(" ", $interests_str);// converts the string to an array which you can easily manipulate foreach ($name_array as $row=>$name) { $username = mysql_real_escape_string($name); $photo = mysql_real_escape_string($_POST['interests'][$row]); mysql_query('INSERT INTO photos (username, photo) VALUES ("' . $username . '", ' . $photo . ')') or die(mysql_error()); } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>array test</title> </head> <body> <form action="array.php" method="post"> <input type="checkbox" name="interests[]" value="Politics" />Politics<br /> <input type="checkbox" name="interests[]" value="Entertainment" /><br /> <input type="checkbox" name="interests[]" value="Tech" /><br /> <input type="checkbox" name="interests[]" value="Health" /><br /> <input type="checkbox" name="interests[]" value="Living" /><br /> <input type="checkbox" name="interests[]" value="Travel" /><br /> <input type="checkbox" name="interests[]" value="World" /><br /> <input type="submit" value="Submit"> </form> </body> </html> </code></pre>

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.
