扩展的mysqli_result在INSERT类型的查询上抛出错误

我像这样扩展了mysqli_result类:

class mysqli_Extended extends mysqli {
public function Execute($query) {
    $this->real_query($query);
    return new mysqliResult_Extended($this);
}

public function Insert_Id() {
    return $this->insert_id;
}

public function Affected_Rows() {
    return $this->affected_rows;
}
}

class mysqliResult_Extended extends MySQLi_Result {
public $fields;
public $queryResults;
public $row_count;
public function __construct($opt) {
    parent::__construct($opt);
    $this->queryResults = $this->fetch_all(MYSQLI_BOTH); <-- this is line 28
    $this->fields = $this->queryResults[0];
    $this->row_count = $this->num_rows; <-- this is line 30
    $this->close(); <-- this is line 31
}

public function getrows() {
    return $this->queryResults;
}

public function recordcount() {
    return $this->row_count;
}
}

每次我执行使用INSERT的查询时,都会出现以下错误:

Warning: mysqli_result::fetch_all() [mysqli-result.fetch-all]: Couldn't fetch mysqliResult_Extended in /home/xxx/xxx/xxx/xxx/dB.class.php on line 28

Warning: mysqliResult_Extended::__construct() [mysqliresult-extended.--construct]: Couldn't fetch mysqliResult_Extended in /home/xxx/xxx/xxx/xxx/dB.class.php on line 30

Warning: mysqli_result::close() [mysqli-result.close]: Couldn't fetch mysqliResult_Extended in /home/xxx/xxx/xxx/xxx/dB.class.php on line 31

如果我执行SELECT类型的查询,则没有错误。

任何可能导致此问题的想法?

答案 0 :(得分:1)

  

“我收到以下错误:”

这些不是错误 - 它们是警告。

尝试var_dump($this->queryResults);,看看你得到了什么。

我的猜测是,在一台服务器上警告被抑制,而另一台服务器则没有警告。

如果要取消警告,可以在函数调用前使用“@”字符,或者按照this question中所示适当设置错误级别。
