    <p>Alexandra,</p> <p>All though this will not solve all of your errors. It has useful comments and will help you zero in on the exact issue. Can you execute this and let me know what you actually see?</p> <pre><code>// try get "MySQL link identifier" $dbConn = mysql_connect($serverName, $user_name, $password) or die("Cannot connect to server&lt;br /&gt;\n MySQL error ==&gt;" . mysql_errno() . "&lt;== : ==&gt;" . mysql_error() . "&lt;== &lt;br /&gt;\n"); print ""; // try connect to database mysql_select_db($db_name, $dbConn) or die("Cannot connect to database&lt;br /&gt;\n MySQL error ==&gt;" . mysql_errno($dbConn) . "&lt;== : ==&gt;" . mysql_error($dbConn) . "&lt;== &lt;br /&gt;\n"); print "&lt;br /&gt;\n"; // Retrieve data from database $id = $_GET['id']; $additional_notes = $_GET['additional_notes']; // Assuming id is always numeric you could sanitize and validate it like below $id = intval($_GET['id']); if( $id&lt;=0 ){ // Let user know or redirect to a page when id is not present // Or even better do not run the queries at all } // update data in mysql database //$sql=("UPDATE `rmstable2` SET `additional_notes` = '$additional_notes' WHERE `id` = '$id'"); // Escape strings; you could try something like this $sql=("UPDATE `rmstable2` SET `additional_notes` = '" . mysql_escape_string($additional_notes) . "' WHERE `id` = '$id'"); </code></pre> <p>// for debugging only (better practice is to use error_log) echo '<pre>SQL: ' . $sql . '</pre>';</p> <pre><code>$result = mysql_query($sql); if($result){ //$resultcount = mysql_num_rows($result); // Instead $resultcount = mysql_affected_rows($result); if ($resultcount == 1) { mysql_query("UPDATE `rmstable2` SET `additional_notes` = '$additional_notes' WHERE `id` = '$id'") or die(mysql_error()); }else{ // Nothing was updated // maybe rows didn't match? echo "No data was updated."; } }else{ // mysql_query returned FALSE // There must be an error echo "DB Error: " . mysql_error(); } // if successfully updated. if($result){ echo "Update Successful!"; echo '&lt;h3&gt;Your case has been updated.&lt;/h3&gt;'; echo "To see your changes please click &lt;a href='/fullcase.php?id=$id'&gt;here&lt;/a&gt;&lt;/b&gt;"; }else { echo "ERROR"; } </code></pre>

    1. COIf you're going to do that, you could at least add the `mysql_error()` check in too.

    2. CODownvoted for missing the point; `mysql_query('UPDATE...')` always returns a boolean. See my answer.

    3. CO@AaronMiller Yes it does. FALSE on SQL error else true or a valid resource pointed. That's why there is `// Instead $resultcount = mysql_affected_rows($result); if ($resultcount == 1) {`

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).
