PHP / MYSQL： 如何使用Normal Where子句并搜索Where子句用于Mysqli查询

$search = $_POST['cloud_edge'];
$cloud_edge = 1;

 $network_countries = $wpdb->get_results('SELECT * From media_networks   WHERE 
 cloud_edge = "'.$cloud_edge.'" AND capital_city LIKE "'%$search%'"  ORDER by 
capital_city  ');

Answer 1

您缺少第二个变量的连接。

<?php
    $search = $_POST['cloud_edge'];
    $cloud_edge = 1;

     $network_countries = $wpdb->get_results('SELECT * From media_networks   WHERE 
     cloud_edge = "'.$cloud_edge.'" AND capital_city LIKE "%'.$search.'%"  ORDER by 
    capital_city  ');

Answer 2

您需要正确连接搜索变量

LIKE "%'.$search.'%"

此外，您无法使用变量添加%，但不会返回结果。试试以下

$network_countries = $wpdb->get_results('SELECT * From media_networks   WHERE 
 cloud_edge = "'.$cloud_edge.'" AND capital_city LIKE "%'.$search.'%"  ORDER by 
capital_city ');
