有谁知道我将如何从fb中的mysql数据库填充数据:随机并迭代它,选择一个随机引用?
FB:随机
$facebook->api_client->fbml_setRefHandle('quotes',
'<fb:random>
<fb:random-option>Quote 1</fb:random-option>
<fb:random-option>Quote 2</fb:random-option>
</fb:random>');
mysql数据:
$rowcount = mysql_result($result, 0, 0);
$rand = rand(0,$rowcount-1);
$result = mysql_query("SELECT cQuotes, vAuthor, cArabic, vReference FROM thquotes LIMIT $rand, 1", $conn)
or die ('Error: '.mysql_error());
$row = mysql_fetch_array($result, MYSQL_ASSOC);
if ( !$row ) {
echo "Empty";
}
else{
$fb_box = "<p>" . h($row['cArabic']) . "</p>";
$fb_box .= "<p>" . h($row['cQuotes']) . "</p>";
$fb_box .= "<p>" . h($row['vAuthor']) . "</p>";
$fb_box .= "<p>" . h($row['vReference']) . "</p>";
}

通常,当我想要获取随机引用或其他数据时,我所做的是选择数据库中的所有id
,将它们提供给数组,然后从中随机选择数组。然后使用id
挑选出您想要的那个。
例如:
$sql = "SELECT `id` FROM `quotes`;";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
$id = rand(1, $count);
$sql = "SELECT `text`,`author` FROM `quotes` WHERE `id`='$id' LIMIT 1;";
$result = mysql_query($sql);
$quote = mysql_fetch_assoc($result);
