Question

我有5个字段名称，分别为first_name，last_name，middle_name，status和barangay_name，我想根据用户想要搜索数据。仅最后一个字段名称为barangay_name的问题正常。其余的不是，我的查询出了什么问题？我只检索活动的受益人，并且内部加入tbl_beneficiary和tbl_barangay。

  public function searchActiveBeneficiary($keyword) {
        $sql = "SELECT tbl_beneficiary.beneficiary_id, 
        tbl_beneficiary.first_name, tbl_beneficiary.last_name, 
        tbl_beneficiary.middle_name, tbl_beneficiary.is_active, 
        tbl_barangay.barangay_name FROM tbl_beneficiary INNER JOIN tbl_barangay 
        ON tbl_barangay.barangay_id = tbl_beneficiary.barangay_id WHERE 
        tbl_beneficiary.is_active = 'Yes' AND tbl_beneficiary.first_name OR 
        tbl_beneficiary.is_active = 'Yes' AND tbl_beneficiary.last_name OR 
        tbl_beneficiary.is_active = 'Yes' AND tbl_beneficiary.middle_name OR 
        tbl_beneficiary.is_active = 'Yes' AND tbl_barangay.barangay_name LIKE 
        :keyword";

        $stmt = $this->connection->prepare($sql);

        $stmt->execute([
            ":keyword" => '%' . $keyword . '%'
        ]);

        return $stmt->fetchAll();
    }

  //vue.js method
  searchActiveBeneficiary : function() {
        axios({
            method : "GET",
            url : this.urlRoot + "beneficiary/search_active_beneficiary.php?keyword=",
            params : {
                keyword : this.search_active_beneficiary
            }
        }).then(function (response){
            vm.active_beneficiaries = response.data;
            console.log(response);
        });
    },

  <?php

    include '../../private/initialize.php';

    $beneficiary = new Beneficiary();

    echo json_encode($beneficiary->searchActiveBeneficiary($_GET['keyword']));

  ?>

这是因为barangay_name是您实际上与关键字进行比较的唯一对象。您需要将表达式的LIKE部分添加到每个条件中。请注意，不必多次指定tbl_beneficiary.is_active = 'Yes'，只需更改WHERE条件的逻辑即可达到相同的效果：

WHERE tbl_beneficiary.is_active = 'Yes'
  AND (tbl_beneficiary.first_name LIKE :keyword OR 
       tbl_beneficiary.last_name LIKE :keyword OR 
       tbl_beneficiary.middle_name LIKE :keyword OR 
       tbl_barangay.barangay_name LIKE :keyword)

如何搜索两个以上的关键字？
