SQL结果截断第一个结果

Question

一系列奇怪的事件。

我有一个网页严格用于构建数据库（超级准系统）。 HTML表单操作在同一页面上-使用PHP语句if(isset($_POST['submit']))更改每个提交的内容。 每次用户提交时，它都会回显This [x] was successfully added. ，然后继续在页面底部显示一个表格。

该表显示了结果，但是第一个结果被截断了。

表格代码：

$host = "x";
$dbusername = "x";
$dbpassword = "x";
$db_name = "x";

mysql_connect("$host","$dbusername","$dbpassword") or die("Cannot connect to database");
mysql_select_db("$db_name") or die("Cannot select database");

// Collect Information
$query = "SELECT * FROM database";

$data = mysql_query($query) or die(mysql_error());

$row = mysql_fetch_array($data);

print "<table border='1px' cellpadding='4px' cellspacing='0'><tr><th>ID</th><th>CELL 1</th><th>CELL 2</th><th>CELL 3</th><th>CELL 4</th><th>CELL 5</th><th>CELL 6</th><th>CELL 7</th><th>CELL 8</th><th>CELL 9</th><th>CELL 10</th><th>CELL 11</th><th>CELL 12</th><th>CELL 13</th><th>CELL 14</th></tr>";
while($row = mysql_fetch_array($data)){
    print "<tr><td>";
print $row['index'];
print "</td><td>";
print $row['CELL 1'];
print "</td><td>";
print $row['CELL 2'];
print "</td><td>";
print $row['CELL 3'];
print "</td><td>";
print $row['CELL 4'];
print "</td><td>";
print $row['CELL 5'];
print "</td><td>";
print $row['CELL 6'];
print "</td><td>";
print $row['CELL 7'];
print "</td><td>";
print $row['CELL 8'];
print "</td><td>";
print $row['CELL 9'];
print "</td><td>";
print $row['CELL 10'];
print "</td><td>";
print $row['CELL 11'];
print "</td><td>";
print $row['CELL 12'];
print "</td><td>";
print $row['CELL 13'];
print "</td><td>";
print $row['CELL 14'];
print "</td></tr>";
}

echo "</table>";

mysql_close();

有任何想法吗？

Answer 1

在进入循环之前，您正在调用mysql_fetch_array()
这会将结果的第一行加载到$row变量中
在while循环中再次调用它时，您将用第二个结果行覆盖第一个结果行

$data = mysql_query($query) or die(mysql_error());

**$row = mysql_fetch_array($data);**

print "<table border='1px' cellpadding='4px' cellspacing='0'><tr><th>ID</th><th>CELL 1</th><th>CELL 2</th><th>CELL 3</th><th>CELL 4</th><th>CELL 5</th><th>CELL 6</th><th>CELL 7</th><th>CELL 8</th><th>CELL 9</th><th>CELL 10</th><th>CELL 11</th><th>CELL 12</th><th>CELL 13</th><th>CELL 14</th></tr>";
while($row = mysql_fetch_array($data)){

删除此行，它也会显示第一行
