Question

我在mysql中添加了一个datetime列。它将当前时间戳作为其值。我在php中回应它时遇到错误。说这是一个未定义的索引。

$sql="SELECT `idea-content` FROM `ideas` ";
$result = mysqli_query($mysql_link, $sql);

if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
    echo "<li>
    <div class='comment-main-level'>
      <!-- Avatar -->
      <div class='comment-avatar'><img src='#' alt=''></div>
      <!-- Contenedor del Comentario -->
      <div class='comment-box'>
        <div class='comment-head'>
          <h6 class='comment-name by-author'><a href='#''>Agustin Ortiz</a></h6>
          <span>".$row['time']."</span>
          <i class='fa fa-reply'></i>
          <i class='fa fa-heart'></i>
        </div>
        <div class='comment-content'>".$row['idea-content']."
        </div>
      </div>
    </div></li>";
        }

Answer 2

您选择了1个字段，但尝试输出2个字段您的选择中缺少time字段，您也可以使用DATE_FORMAT格式化日期

$sql="SELECT `idea-content`, DATE_FORMAT(`time`, '%W %M %Y') as `time` FROM `ideas` ";

无法在PHP中回显当前的DateTime
