仅以html格式显示First Fetched字段

时间：2017-02-16 03:12:24

标签： php mysql

仅在表单的第一个字段中显示值，即使这些字段具有值，所有其他字段也显示为空白

我从mySql查询中获取了许多字段，但它只显示了第一个获取的字段，如果我将第一个获取字段的名称复制为表单所有输入框的值，则只显示第一个其他字段为空白。 当我回显这些列时，其他列显示值。

您错过了value =''参数，并且您出于某种原因尝试输出相同的$ NM1变量。将代码更改为：

答案 1 :(得分：0)

我可以在这里看到两个问题

  1. 一个是你使用 mysqli_fetch_array 。实际上你需要使用 mysqli_fetch_assoc
    2. 每个输入字段中都缺少
  2. 值属性。

    3. 您可以尝试以下代码。
