嗨所以这是代码: 它是一个页面,用于在下拉列表中显示数据库中的可用表,然后在表中显示结果。这样做的实际代码(在中间)可以完全独立工作,但当我尝试在其周围添加模板时,我会收到错误...

它一直说出意想不到的结局,但我不确定如何解决它?

答案 0 :(得分:12)
当服务器不支持short-open-tags
(<?
而不是<?php
)时混合使用短标记和常规标记时,也可能发生这种情况,即使您的情况并非如此代码。
<?php
$showHeader = true;
if ($showHeader) {
?>
<h1>Hello, World!</h1>
<?
}
?>
请注意,如果服务器不支持<?
打开标记,则不会注册结束括号。
答案 1 :(得分:11)
第50行:if (mysql_select_db($dbname, $conn))
有一个左括号而不是结束符号。
答案 2 :(得分:3)
您可能需要将<?
更改为<?php
答案 3 :(得分:0)
您忘记使用}
:
if (mysql_select_db($dbname, $conn))
{
?>
试试这段代码:
<?php
$dbname = 'snysbarchive';
$conn= mysql_connect('localhost', 'root', 'usbw');
if (!$conn) {
echo 'Could not connect to mysql';
exit;
}
$sql = "SHOW TABLES FROM $dbname";
$result = mysql_query($sql);
if (!$result) {
echo "DB Error, could not list tables\n";
echo 'MySQL Error: ' . mysql_error();
exit;
}
if (mysql_select_db($dbname, $conn))
{
?>
<form method="post" action="new 2.php">
<select name="tables">
<?php
while ($row = mysql_fetch_row($result)) {
echo '<option value="'.$row[0].'">'.$row[0].'</option>';
}
?>
</select>
<input type="submit" value="Show">
</form>
<?php
}
//mysql_free_result($result);
if (isset($_POST) && isset($_POST['tables']))
{
$tbl=$_POST['tables'];
//echo $_POST['tables']."<br />";
$query="SELECT * from $tbl";
$res=mysql_query($query);
echo $query;
if ($res)
{
?>
<table border="1">
<?php
while ( $row = mysql_fetch_array($res))
{
echo "<tr>";
echo "<td>".$row[0]."</td>";
echo "<td>".$row[1]."</td>";
echo "<td>".$row[2]."</td>";
echo "<td>".$row[3]."</td>";
echo "</tr>";
}
?>
</table>
<?php
}
}
?>

你错过了一个&#39;}&#39;如果块没有关闭,请关注。
if (mysql_select_db($dbname, $conn))
{
通过在#91行中添加},您的代码将会正常运行。
但总是尝试通过遵循最佳实践来编写更清晰的代码。
答案 5 :(得分:-1)
您没有在函数周围选择正确的大括号来选择数据库。
