調用一個成員函數NUM_ROWS（）布爾在/home/alabbrkq/public_html/system/database/DB_query_builder.php

Question

public function count_all_results($table = '', $reset = TRUE) 
{ 
    if ($table !== '') 
    { 
     $this->_track_aliases($table); 
     $this->from($table); 
    } 

    $result = ($this->qb_distinct === TRUE) 
     ? $this->query($this->_count_string.$this->protect_identifiers('numrows')."\nFROM (\n".$this->_compile_select()."\n) CI_count_all_results") 
     : $this->query($this->_compile_select($this->_count_string.$this->protect_identifiers('numrows'))); 

    if ($reset === TRUE) 
    { 
     $this->_reset_select(); 
    } 

    if ($result->num_rows() === 0) // this is the line with the issue 
    { 
     return 0; 
    } 

    $row = $result->row(); 
    return (int) $row->numrows; 
} 

笨 客戶都在抱怨上提交他們的訂單我的網站有問題，結賬。當我檢查錯誤日誌時，這是我看到的錯誤。我怎樣才能解決這個

Answer 1

var = (condition x) ? y : z; 
condition ? true : false; 

在這裏，我們有真正的「Y」和虛假的「Z」被宣佈爲根據VAR條件。在你的問題中，錯誤表示操作在Boolean上執行，這意味着Y或Z正在返回Boolean而不是值。

請檢查由Y或Z申報的價格，並打印出來的連擊調試，必須有方法你調用或方法返回Boolean，而不是其所需的代碼點火器數據庫庫執行操作Database Object錯誤。

請編輯您的問題，並提供您的連擊方法和準確的答案你的問題。
