Thinkphp或查询使用

if ($_GET[\'machine_type_id\']) {
    $machine_type_id = trim($_GET[\'machine_type_id\']);
    $where[\'machine_type_id\'] = $machine_type_id;
}

if ($_GET[\'keywords\']) {
    $keywords = trim($_GET[\'keywords\']);
    $map = [];
    $map[\'machine_type_name\']  = $keywords;
    $map[\'keywords\']  = array(\'like\', \'%\'.$keywords.\'%\');
    $map[\'_logic\'] = \'or\';
    $where[\'_complex\'] = $map;
}

$where[\'is_show\'] = 1;
$where[\'is_del\'] = 0;

这里通过一个变量，巧妙的实现了或查询。

最终生成的语句如下：

SELECT * FROM `tf_photo_tutorial` WHERE (  ( `machine_type_name` = \'D850\' ) OR ( `keywords` LIKE \'%D850%\' ) ) AND ( `is_show` = 1 ) AND ( `is_del` = 0 )；
