Question

好的，所以我还是有点新手我有一个名为字段的字段，当创建一个新的字段来存储数据库中的值时。我想要做的是将数据带回来，并将会话数组命名为字段名称，以便它们自动生成。

这是我的代码

session_start(); 
$_SESSION['fields'][$y]=$row['fields']; 
echo $_SESSION['fields'][$y]; 
echo""; 
$f= $_SESSION['fields'][$y]; 
echo $f; 
echo""; 
$_SESSION[$f][$y]=$row[$f]; 
echo $_SESSION[$f][1]; ; $y++;

嗨我有同样的问题..我通过以下方式解决了问题：

在函数wpdb中使用wordpress build 不要使用session_start，因为wordpress触发session_start（）;

有任何问题请与我联系：pimenteljchristopher@gmail.com

global $wpdb;
$table_name = $wpdb->prefix . "table_name";
$result = $wpdb->get_results ( "SELECT * FROM $table_name" );

foreach ( $result as $print )   {
    echo $print->id;
    echo $print->fields1;
    echo $print->fields2;
}

如果我理解正确，您只想将数据库中的行返回到会话中，以便稍后可以使用它来构建HTML元素：

session_start();

$mysqli = new mysqli('host', 'user', 'pass', 'database');
if($stmt = $mysqli->prepare('SELECT * from FIELDS where 1')):
    $stmt->execute();
    $fields = $stmt->get_result(); //so we can use fetch array and simplify this process
    while($row = $stmt->fetch_array(MYSQLI_ASSOC)):  //foreach result set, return an associative array
        $_SESSION['fields'][] = $row; //push the array into your fields session
    endwhile;
    $stmt->close(); //close your statement
endif;
$myslqi->close(); //drop the mysqli connection, we're done

print_r($_SESSION['fields']); //lets see what fields looks like now

$ret = '';
foreach($_SESSION['fields'] as $row): //foreach row in sessions
    $ret .= '<div>'; //parent container for all fields in this row
    foreach($row as $idx => $field): //foreach field in the row## Heading ##
        $ret  .= '<span>'. $field . '</span>'; //create a div element to contain the field
    endforeach;
    $ret . = '</div>'; //close the parent container
endforeach;

echo $ret; //returned the constructed HTML for the fields

如何在mysql中使用变量来获取行数据？
