问题描述
在服务器上更新PHP之后,我对mysql_query有一些问题.当前版本的PHP中不推荐使用代码中的2个函数:mysql_fetch_array()mysql_query()
Afetr updating php on the server i have some problems with mysql_query. There are 2 functions in your code that have been deprecated in the current version of PHP :mysql_fetch_array()mysql_query()
global $table_prefix, $wpdb;
// caching database query per comment
$ck_cache = array('ck_ips'=>"", 'ck_comment_id'=>0, 'ck_rating_up'=>0, 'ck_rating_down'=>0);
$table_name = $table_prefix . "comment_rating";
if($wpdb->get_var("SHOW TABLES LIKE '$table_name'") != $table_name)
{
temckrating_install();
}
function temckrating_install() //Install the needed SQl entries.
{
global $table_prefix, $wpdb;
$table_name = $table_prefix . "comment_rating";
$sql = 'DROP TABLE `' . $table_name . '`'; // drop the existing table
mysql_query($sql);
$sql = 'CREATE TABLE `' . $table_name . '` (' //Add table
. ' `ck_comment_id` BIGINT(20) NOT NULL, '
. ' `ck_ips` text NOT NULL, '
. ' `ck_rating_up` INT,'
. ' `ck_rating_down` INT'
. ' )'
. ' ENGINE = myisam;';
mysql_query($sql);
$sql = 'ALTER TABLE `' . $table_name . '` ADD INDEX (`ck_comment_id`);'; // add index
mysql_query($sql);
// echo "comment_rating tables created";
$ck_result = mysql_query('SELECT comment_ID FROM ' . $table_prefix . 'comments'); //Put all IDs in our new table
while($ck_row = mysql_fetch_array($ck_result, MYSQL_ASSOC)) //Wee loop
{
mysql_query("INSERT INTO $table_name (ck_comment_id, ck_ips, ck_rating_up, ck_rating_down) VALUES ('" . $ck_row['comment_ID'] . "', '', 0, 0)");
}
}
function temckrating_comment_posted($ck_comment_id) //When comment posted this executes
{
global $table_prefix, $wpdb;
$table_name = $table_prefix . "comment_rating";
mysql_query("INSERT INTO $table_name (ck_comment_id, ck_ips, ck_rating_up, ck_rating_down) VALUES ('" . $ck_comment_id . "', '" . getenv("REMOTE_ADDR") . "', 0, 0)"); //Adds the new comment ID into our made table, with the users IP
}
// cache DB results to prevent multiple access to DB
function temckrating_get_rating($comment_id)
{
global $ck_cache, $table_prefix, $wpdb;
// return it if the value is in the cache
if ($comment_id == $ck_cache['ck_comment_id']) return;
$table_name = $table_prefix . "comment_rating";
$ck_sql = "SELECT ck_ips, ck_rating_up, ck_rating_down FROM `$table_name` WHERE ck_comment_id = $comment_id";
$ck_result = mysql_query($ck_sql);
$ck_cache['ck_comment_id'] = $comment_id;
if(!$ck_result) {
$ck_cache['ck_ips'] = '';
$ck_cache['ck_rating_up'] = 0;
$ck_cache['ck_rating_down'] = 0;
mysql_query("INSERT INTO $table_name (ck_comment_id, ck_ips, ck_rating_up, ck_rating_down) VALUES ('" . $comment_id . "', '', 0, 0)");
}
else if(!$ck_row = mysql_fetch_array($ck_result, MYSQL_ASSOC)) {
$ck_cache['ck_ips'] = '';
$ck_cache['ck_rating_up'] = 0;
$ck_cache['ck_rating_down'] = 0;
mysql_query("INSERT INTO $table_name (ck_comment_id, ck_ips, ck_rating_up, ck_rating_down) VALUES ('" . $comment_id . "', '', 0, 0)");
}
else {
$ck_cache['ck_ips'] = $ck_row['ck_ips'];
$ck_cache['ck_rating_up'] = $ck_row['ck_rating_up'];
$ck_cache['ck_rating_down'] = $ck_row['ck_rating_down'];
}
}
我尝试用$ wpdb-> get_results替换mysql_query,但仍然出现错误
I try to replace mysql_query with $wpdb->get_results but still get errors
推荐答案
mysql_query return
资源.因此,使用$wpdb->get_results
会收到此错误.
mysql_query return
a resource. So you get this error by using $wpdb->get_results
.
mysql_query() returns TRUE
或error
上的FALSE
.返回的结果资源应传递给mysql_fetch_array()
和其他用于处理结果表的函数,以访问返回的数据.
mysql_query() returns TRUE
on success or FALSE
on error
. The returned result resource should be passed to mysql_fetch_array()
, and other functions for dealing with result tables, to access the returned data.
您将替换$ wpdb-> get_results的2个函数mysql_fetch_array()
和mysql_query
实例.您将定义返回类型-ARRAY_A, ARRAY_N , OBJECT ,OBJECT_K
You will replace 2 function mysql_fetch_array()
and mysql_query
instance of $wpdb->get_results. You will define return type -- ARRAY_A, ARRAY_N , OBJECT ,OBJECT_K
global $wpdb;
$ck_sql = $wpdb->get_results("SELECT ck_ips, ck_rating_up, ck_rating_down FROM `$table_name` WHERE ck_comment_id = $comment_id", ARRAY_A);
foreach($ck_sql as $row) {
echo $row['ck_ips'] . ' ' . $row['ck_rating_up']. ' ' . $row['ck_rating_down '];
}
这篇关于将mysql_query转换为$ wpdb-> get_results的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
