Question

奇怪的一系列事件。

我有一个严格用于构建数据库（超级准系统）的网页。 HTML表单操作位于同一页面 - 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。

该表显示结果，但第一个结果被截断。

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();

有什么想法吗？

你在进入循环之前打电话给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，用第二个结果覆盖第一个结果行

$data = mysql_query($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

SQL结果截断第一个结果
