Question

嗨，大家好，我有一個在PHP更新記錄查詢問題。

<?php 
include('../webcgo/script/cox.php'); 
$query = $cox->query("SELECT cf_id FROM offerte;"); 
while ($idx = mysqli_fetch_array($query)) { 
    $check = '<button class="uk-button" onclick="location.href=\'http://localhost/chartscript/remRegola.php?dis=2&id=' . $idx['cf_id'] . '\'">OK</button>'; 
    $query_check = 'UPDATE offerte SET check=\'' . $check . '\' WHERE cf_id=' . $idx['cf_id'].';'; 
    if ($queryx = $cox->query($query_check) === TRUE) { 
     echo "Record updated successfully"; 
    } else { 
     echo "Error updating record: " . $cox->error; 

    } 
} 
mysqli_close($cox);?> 

結果： 錯誤更新記錄：您的SQL語法錯誤;檢查對應於您的MySQL服務器版本的手冊，以便在'check ='處使用正確的語法'

check是MySQL reserved keyword。如果你打算在查詢中使用它，你必須包裹它反引號：

$query_check = 'UPDATE agoragroup_chronoforms_data_inserimento_offerte_prod SET `check`=\'' . $check . '\' WHERE cf_id=' . $idx['cf_id'].';';
