我使用下面的代码选择项目并使用$ result变量进行计数。如果小于1,则表示添加更多,如果大于5,则表示查看全部。它适用于不到1但不会超过5.我做得对吗?
//查询
$sql = "SELECT id, name, why, date_time
FROM tabs
WHERE p_id = '$pid'
ORDER BY id
LIMIT 0, 5";
$result = mysql_query($sql);
$query = mysql_query($sql) or die ("Error: ".mysql_error());
if ($result == "") {
echo "";
}
echo "";
$rows = mysql_num_rows($result);
if($rows == 0) {
print("");
} elseif($rows > 0) {
while($row = mysql_fetch_array($query)) {
$name = $row['name'];
$w = nl2br($row['why']);
$y = $row['date_time'];
print("echoing contents here");
}
}
if(mysql_num_rows($result) > 5) {
echo "view all";
}
if(mysql_num_rows($result) < 1) {
echo "add one";
} ?>
答案 0 :(得分:2)
if(mysql_num_rows($result) > 5) {
echo "view all";
}
if(mysql_num_rows($result) < 1) {
echo "add one";
}
应该是
if($rows > 5) {
echo "view all";
}
if($rows < 1) {
echo "add one";
}
由于您使用前一个mysql_fetch_array()
循环
