I'm trying to get the last 7 records from a table whose records were entered by the user
Here is my query:
$database->setQuery("SELECT * FROM #__mytable WHERE (user_id = '$uid')");
$dberr="";
if (!$database->query()) {
$dberr = $database->getErrorMsg();
}
if(!$dberr==""){
echo($dberr."<br>");
}else{
$rows = $database->loadObjectList();
How do I cycle thru the $rows to get the last 7?
您不会:
SELECT * FROM ... WHERE ... ORDER BY user_id DESC LIMIT 7
SELECT *
FROM #__mytable
WHERE user_id = '$uid'
ORDER BY
entered_date DESC
LIMIT 7
To get them in ascending order, use:
SELECT *
FROM (
SELECT *
FROM #__mytable
WHERE user_id = '$uid'
ORDER BY
entered_date DESC
LIMIT 7
) q
ORDER BY
entered_date
SELECT * FROM #__mytable WHERE (user_id = '$uid') ORDER BY id DESC LIMIT 0,7
