好的,所以我被告知最好转换到新的mysqli 所以我一直在一个新的网站上工作,到目前为止一直很好,但我遇到了一个问题,我无法弄清楚如何将其转换为我的搜索查询
我在我的网站上添加了搜索功能,但现在我无法使用它。
这是我的旧代码:
1. Open Services (services.msc) and restart MySQL57 service.
2. Execute the following commands in MySQL.
use <<database name>>;
set global optimizer_switch='derived_merge=OFF';
3. Update the .edmx.
我已将代码升级为用户oo
这就是我所拥有的:
$query = "SELECT * FROM snippet_tools WHERE `db_title` LIKE ".sql_val('%'.$_GET['search'].'%')." OR `db_body`=".sql_val('%'.$_GET['search'].'%');
$result = mysql_query($query) or die("<b>A fatal MySQL error occured</b>.<br />Query: ".$query."<br />Error: (".mysql_errno().") ".mysql_error());
$anymatches = mysql_num_rows($result);
if ($anymatches == 0 ) {
但每次我运行它来执行搜索时,我都会收到此错误消息:
注意:尝试在第611行的H:\ root \ site5 \ questions.php中获取非对象的属性

您可以参考W3学校网站,了解MySQL和MySQLi的变体及其功能。继续你的项目真的很有帮助。

尝试这种方法!
<?php
error_reporting(E_ALL);
$servername = "localhost"; $username = "root"; $password = "root"; $dbname = "cities";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$get = array('search' => "Lon");
$sql_search = "SELECT * FROM cities WHERE (city_name LIKE '%$get[search]%')";
$result = $conn->query($sql_search);
$anymatches = $result->num_rows;
if ($anymatches == 0 ){
echo "No matches!";
}
else
{
echo $anymatches . " match found!";
}
?>
