Question

我有一个包含5列的数据库：join_date，week，done，should和comment。

我有一个insert.php文件：

<body>
<div id="insert">
<?php
if(isset($_POST['add']))
{
$dbhost = 'host';
$dbuser = 'user';
$dbpass = 'pass';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
  die('Could not connect: ' . mysql_error());
}

if(! get_magic_quotes_gpc() )
{
   $join_date = addslashes ($_POST['join_date']); 
   $week = addslashes ($_POST['week']);
   $done = addslashes ($_POST['done']);
   $should = addslashes ($_POST['should']);
   $comment = addslashes ($_POST['comment']);

}
else
{
   $join_date = addslashes ($_POST['join_date']);
   $week = addslashes ($_POST['week']);
   $done = addslashes ($_POST['done']);
   $should = addslashes ($_POST['should']);
   $comment = addslashes ($_POST['comment']);
}


$sql = "INSERT INTO statistika2014 ".
       "(join_date, week, done, should, comment ) ".
       "VALUES('$join_date','$week','$done','$should', '$comment', NOW())";
mysql_select_db('table');
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
  die('Could not enter data: ' . mysql_error());
}
echo "Entered data successfully\n";
mysql_close($conn);
}
else
{
?>
<form method="post" action="<?php $_PHP_SELF ?>">
<table width="400" border="0" cellspacing="1" cellpadding="2">
<tr>
<td><input name="join_date" type="date" id="join_date" ></td>
</tr>
<tr>
<td><input name="week" type="number" id="week" placeholder="week"></td>
</tr>
<tr>
<td><input name="done" type="number" id="emp_done" placeholder="done"></td>
</tr>
<tr>
<td><input name="should" type="number" id="should" placeholder="should"></td>
</tr>
<tr>
<td><input name="comment" type="text" id="comment" placeholder="comment"></td>
</tr>
<tr>
</tr>
<tr>
<td>
<input name="add" type="submit" id="add" value="Submit">
</td>
</tr>
</table>
</form>
<?php
}
?>
</div>  
</body>

当我使用这个insert.php文件时，我收到消息：＆＃34;无法输入数据：列数与第1行和第34行的值计数不匹配; 但我不懂！我有5列和5个值，或者我错了吗？

我正在使用免费主机。他们是否有可能需要刷新一些东西？

请帮忙

Answer 1

学会数数？

  "(join_date, week, done, should, comment ) ".
      1         2       3   4        5
   "VALUES('$join_date','$week','$done','$should', '$comment', NOW())";
               1           2       3        4          5         6???

从什么时候开始5 == 6？

Answer 2

您输入Now（）作为第六个值

Answer 3

你的values子句有一个额外的字段NOW（），它对5个字段产生6个值。

       "(join_date, week, done, should, comment ) ".
   "VALUES('$join_date','$week','$done','$should', '$comment', NOW())";

Answer 4

你要么想要这个......

//assuming your time column is named timestamp

$sql = "INSERT INTO statistika2014 ".
   "(join_date, week, done, should, comment, timestamp ) ".
   "VALUES('$join_date','$week','$done','$should', '$comment', NOW())";

或者这......

// Just set your 6th column to TIMESTAMP in your DB and it will auto update on a new insert
$sql = "INSERT INTO statistika2014 ".
   "(join_date, week, done, should, comment ) ".
   "VALUES('$join_date','$week','$done','$should', '$comment')";

但您明确尝试将6个值插入5列。在SQL调用中添加第6列。或者将其设置为自动将数据库中的时间戳更新为NOW，并将其从通话中删除

Answer 5

您需要为日期或数据库中调用字段添加另一个字段。

    $sql = "INSERT INTO statistika2014 ".
    "(join_date, week, done, should, comment, date ) ".
    "VALUES('$join_date','$week','$done','$should', '$comment', NOW())";

列数与值计数不匹配，但我认为它确实如此？
