迭代 fb:random

发布于 2024-08-29 07:32:50 字数 900 浏览 3 评论 0原文

有谁知道我如何将 mysql 数据库中的数据填充到 fb:random 中并迭代它，以选择随机报价？

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>";
}

$row = mysql_fetch_array($result, MYSQL_ASSOC);
if ( !$row ) {
  echo "Empty";

一般来说，当我想要获取随机报价或其他数据时，我所做的就是选择数据库中的所有 id，将它们输入到一个数组中，然后从数组。然后使用 id 选择您想要的。

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);

Generally, what I do when I want to pick up a random quote or other piece of data is I select all of the ids in the database, feed them into an array, and then choose at random from the array. Then use the id to pick out the one you want.

For example:

$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);
