我在插入和搜索 MYSQL 数据库时遇到问题。如果我插入数据，它会同时添加和搜索，反之亦然。我想一次只表演一个。我将它们都放在 html 表单上的单独按钮上。有什么想法吗？
<?php
$host = "localhost";
$user = "root";
$password = "pass";
$dbname = "server";
$link = mysql_connect(localhost, root, pass, server);
if (!$link) {
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db(server, $link);
if (!$db_selected) {
die('Can\'t use ' . DB_NAME . ': ' . mysql_error());
}
$sql = "INSERT INTO nameOne" . "(firstName, lastName, phone, address, city, state, zip, birthdate, userName, sex, relationship)".
"VALUES ('$firstName', '$lastName', '$phone', '$address', '$city', '$state', '$zip', '$birthdate', '$userName', '$sex', '$relationship')";
mysql_select_db('server');
$retval = mysql_query( $sql, $link );
if(! $retval ) {
die('Could not enter data: ' . mysql_error());
}
echo "Entered data successfully\n";
$query = sprintf("SELECT firstName, lastName, phone, address, city, state, zip, birthdate, userName, sex, relationship FROM nameOne
WHERE firstname='%s' AND lastname='%s'",
mysql_real_escape_string($firstName),
mysql_real_escape_string($lastName));
$result = mysql_query($query);
if (!$result) {
$message = 'Invalid query: ' . mysql_error() . "\n";
$message .= 'Whole query: ' . $query;
die($message);
}
while ($row = mysql_fetch_assoc($result)) {
echo $row['firstName'];
echo $row['lastName'];
echo $row['phone'];
echo $row['address'];
echo $row['city'];
echo $row['state'];
echo $row['zip'];
echo $row['birthdate'];
echo $row['userName'];
echo $row['sex'];
echo $row['relationship'];
}
mysql_close($link);

最佳答案
使用以下结构的 PHP 代码:
<?php
// here your database connection
if (isset($_POST['submit'])) {
// your insert code here
}
if (isset($_POST['update'])) {
// your update code here
}
if (isset($_POST['search'])) {
// your search code here
}
首先，我建议您使用mysqli，其次将搜索表单与插入和更新表单分开。喜欢:
<form action="search.php" method="post">
<input type="submit" name="search" value="search">
</form>
然后在search.php中编写PHP搜索代码并显示。
