I made a slight mistake when calling the error handler too, it should be:

…or die(sql_error((mysql_errno(), mysql_error(), $repair, realpath(__FILE__), __LINE__));

$repair = mysql_query(”REPAIR TABLE “.$col_value.” QUICK”) or die(’Query failed: ‘ . mysql_error());

I’ve been trying to figure out a way around this and the only one I can think of is to use an error handler that also unlocks the table. e.g:

…or die((mysql_errno(), mysql_error(), $repair, realpath(__FILE__), __LINE__);

$unlock = mysql_query(”UNLOCK TABLES”) or die(’Query failed: ‘ . mysql_error());

Then your error handler could be someting like:

function sql_error($errno, $error, $query, $file, $line)
{
define(”SQL_ERRNO”, $errno);
define(”SQL_ERROR”, $error);
define(”SQL_QUERY”, $query);
define(”SQL_FILE”, $file);
define(”SQL_LINE”, $line);

mysql_query(”UNLOCK TABLES”);
trigger_error(”sql”, E_USER_ERROR);
}

function error_handler($errno, $error, $file, $line)
{
if ($error == “sql”)
{
echo “An Error Has Occurred[$errno] “.SQL_ERROR.”Query: “.SQL_QUERY.”File: “.SQL_FILE.”Line: “.SQL_LINE.”PHP: “.PHP_VERSION.” (”.PHP_OS.”)”;
}
else
{
echo “An Error Has Occurred“;
}
}
