这是search.php的代码-这部分显示搜索文本框和搜索按钮。将从数据库获取数据。
<?php
//Just declaration here for null
$search_term = '';
search_results = false;
//Check if search data was submitted
if (isset($_GET['s'])) {
// Include the search class
require_once( dirname(__FILE__) . '/class-search.php' );
// Instantiate a new instance of the search class
$search = new search();
// Store search term into a variable
$search_term = $_GET['s'];
// Send the search term to our search class and store the result
$search_results = $search->search($search_term);
}
?>

echo $search_result->cust_ic;
?>

<?php

是class-search.php的代码
class search {
private $mysqli;
public function __construct() {
$this->connect();
}
private function connect() {
$this->mysqli = new mysqli( 'localhost', 'root', 'root', 'abc' );
}
public function search($search_term) {
$sanitized = $this->mysqli->real_escape_string($search_term);
// Run the query
$query = $this->mysqli->query("
SELECT *
FROM customer_info
WHERE cust_name LIKE '%{$sanitized}%'
OR cust_ic LIKE '%{$sanitized}%'
");
// Check results
if ( ! $query->num_rows ) {
return false;
}
// Loop and fetch objects
while( $row = $query->fetch_object() ) {
$rows[] = $row;
}
// Build our return result
$search_results = array(
'count' => $query->num_rows,
'results' => $rows,
);
return $search_results;
}
}
我得到这个错误代码:
通知:未定义变量:search_term in C:'xampp'htdocs'search'search.php on line 28
注意:未定义变量:search_results在C:'xampp'htdocs'search'search.php第34行
当我运行search.php时，我得到2个错误。我试着点击搜索，搜索后没有更多的错误出现。对这个解决方案有什么想法吗?谢谢你
请声明您的变量:
<?php
//Declaration
$search_term = '';
search_results = false;
//Check if search data was submitted
if (isset($_GET['s'])) {
// Include the search class
require_once( dirname(__FILE__) . '/class-search.php' );
// Instantiate a new instance of the search class
$search = new search();
// Store search term into a variable
$search_term = $_GET['s'];
// Send the search term to our search class and store the result
$search_results = $search->search($search_term);
}
?>
