Body
<p>I have generated a 10 digit number, added it to a database after purchase.</p> <p>Now I want to make a php page to give users an input box, ask them to enter the 10 digit number, and click submit. After you click submit it should return if the pin is used or has not been used it. (Used if its not available - Not used if its in the table) </p> <p>I got the following code:</p> <pre><code><?php require_once 'db.php'; function validated_pin($pin) { $pin = mysql_real_escape_string($pin); // SECURITY! $result = mysql_query("SELECT pins FROM pins WHERE pin='$pin' LIMIT 1"); if (mysql_fetch_row($result)) { return 'This pin has already been used'; } else { return 'This pin is available for use'; } } echo '<html><center> <form action="' . $_SERVER['SCRIPT_NAME'] . '" method="post"> <table style="border:0px solid black;"> <tr> <td>PIN*:</td><td><input type="text" name="pin" value="" class="bginput"/></td> </tr> <tr> <td></td><td><input type="submit" id ="submit" name="submit1" value="Check Pin>>" class="button"></td> </tr> </table>'; echo validated_pin($pin); echo '</center></html>'; ?> </code></pre> <p>And PHPmyAdmin looks like this: <a href="http://gyazo.com/67c3df7171c83c677cb221c04d644ed7.png" rel="nofollow">http://gyazo.com/67c3df7171c83c677cb221c04d644ed7.png</a></p> <p>It's located in _donation and in table name pins</p> <p>I don't know whats going on tried looking everywhere </p> <p>The current code will return this error</p> <pre><code>Warning: mysql_fetch_row() expects parameter 1 to be resource, boolean given in /home/website/public_html/directory/example.php on line 8 </code></pre>

Guidance

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.
