我在一个页面上有三个按钮，我想在同一页面上提交该表单，根据按钮按下，相应的查询将运行。但是脚本有一些问题。

<?php
$db = mysql_connect('localhost', 'root', '') or
die ('Unable to connect. Check your connection parameters.');
mysql_select_db('easy_excel', $db) or die(mysql_error($db));

if ($_POST['submit'] =='delete_aabb') 
{
$query ='DELETE FROM aabb';
mysql_query($query, $db) or die(mysql_error($db));
echo 'All Data from aabb Deleted succecfully!';
}
elseif ($_POST['submit'] =='delete_bbcc') {
$query ='DELETE FROM bbcc';
mysql_query($query, $db) or die(mysql_error($db));
echo 'All Data from bbcc Deleted succecfully!';
}
elseif ($_POST['submit'] =='show_bbcc') {
$query = 'SELECT
name
FROM  bbcc';
$result = mysql_query($query, $db) or die(mysql_error($db));

echo '<table border="1">';
while ($row = mysql_fetch_assoc($result)) {
echo '<tr>';
foreach ($row as $value) {
echo '<td>' . $value . '</td>';
}
echo '</tr>';
}
echo '</table>';
}
?>

<html>
<head>
<title>Say My Name</title>
</head>
<body>
<form action="#" method="post">
<table>
<tr>
<input type="submit" name="submit" value="delete_aabb" />
</tr>

<tr>
<input type="submit" name="submit" value="delete_bbcc" /></td>
</tr>

<tr>
<input type="submit" name="submit" value="show_bbcc" /></td>
</tr>

</table>
</form>
</body>
</html>

此脚本未运行。请帮我。

我建议您使用MySQLi而不是弃用的MySQL。我认为您指的是isset()功能。

<html>
<head>
<title>Say My Name</title>
</head>
<body>

<?php

/* ESTABLISH CONNECTION USING MYSQLi */

$con=mysqli_connect("localhost","root","","easy_excel");

if(mysqli_connect_errno()){

echo "Error".mysqli_connect_error();
}

if (isset($_POST['delete_aabb'])) /* IF DELETE_AABB IS CLICKED */
{
mysqli_query($con,"DELETE FROM aabb");
echo 'All Data from aabb Deleted succecfully!';
}
else if (isset($_POST['delete_bbcc'])) { /* IF DELETE_BBCC IS CLICKED */
mysqli_query($con,"DELETE FROM bbcc");
echo 'All Data from bbcc Deleted succecfully!';
}
else if (isset($_POST['show_bbcc'])) { /* IF SHOW_BBCC IS CLICKED */
$result=mysqli_query($con,"SELECT name FROM bbcc");

echo '<table border="1">';
while ($row = mysqli_fetch_assoc($result)) {
echo '<tr>';
foreach ($row as $value) {
echo '<td>' . $value . '</td>';
}
echo '</tr>';
}
echo '</table>';
}
?>

<form action="" method="POST">
<table>
<tr>
<input type="submit" name="submit" value="delete_aabb" name="delete_aabb"/>
</tr>

<tr>
<input type="submit" name="submit" value="delete_bbcc" name="delete_bbcc"/></td>
</tr>

<tr>
<input type="submit" name="submit" value="show_bbcc" name="show_bbcc"/></td>
</tr>

</table>
</form>
</body>
</html>
