php - PHP 多个下拉框表单使用 OR 提交到 MySQL

Question

这个问题类似于PHP Multiple Dropdown Box Form Submit To MySQL，但有一点不同。

假设我们有一个 HTML 多选，它被提交到 PHP 后端。

你如何优雅地创建一个带有 OR 条件的多选值的 mysql 请求？

例如，我有一个带有运动列表的多选。怎么做：

SELECT * FROM sports WHERE sport.name=:sport1 OR sport.name=:sport2 OR sport.name=:sport3...

Answer 1

SELECT * FROM sports WHERE sports.name IN ('football','hockey','soccer','trolling');

Answer 2

这是未经测试的，只是一个想法......

$_POST['sports'] = array('basketball', 'baseball', 'football', 'soccer');

$sql = sprintf("SELECT * FROM sports WHERE sport.name IN (%s)", implode( ',', array_fill(1,count($_POST['sports']), '?') ) );
// SELECT * FROM sports WHERE sport.name IN (?,?,?,?) 
$st = $dbh->prepare($sql);

// bind all values
foreach( $_POST['sports'] as $i => $sport) {

    $st->bindValue( ++$i, $sport );

}

$st->execute();

Answer 3

$_POST['sports'] = array('basketball', 'baseball', 'football', 'soccer');

$sql = sprintf("SELECT * FROM sports WHERE sport.name IN (%s)", implode(',', $_POST['sports']));

应该导致

SELECT * FROM sports WHERE sport.name IN (basketball,baseball,football,soccer)
