這是代碼，不起作用 -<form method="post"> <input type="submit" name="zapis" id="zapisk" value="Запис" /><br/></form><?phpfunction zapisk(){$servername = "localhost"; $username = "test"; $password = ""; $dbname = "myDB";// Create connection $conn = new mysqli($servername, $username, $password, $dbname);// Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "INSERT INTO MyGuests (firstname, lastname, email)VALUES ('John', 'Doe', 'john@example.com')"; if ($conn->query($sql) === TRUE) { echo "New record created successfully"; } else { echo "Error: " . $sql . "<br>" . $conn->error; } $conn->close();}//{echo "Your test function on button click is working";}//if(array_key_exists('zapis',$_POST)){zapisk();}?>如果我激活最后兩行，此時(shí)作為評(píng)論，該功能將起作用。是否有可能，該功能可以在不使用最后兩行的情況下工作。

zapisk提交表單時(shí)必須調(diào)用函數(shù)。
<form method="post">
<input type="submit" name="zapis" id="zapisk" value="Запис" /><br/>
</form>
<?php
function zapisk(){
$servername = "localhost";
$username = "test";
$password = "";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
}
// Check form submitted and post has zapis value.
if(!empty($_POST['zapis'])){
zapisk();
}
?>
或者您不使用函數(shù)并在 if 語(yǔ)句中編寫(xiě)代碼：
<form method="post">
<input type="submit" name="zapis" id="zapisk" value="Запис" /><br/>
</form>
<?php
// Check form submitted and post has zapis value.
if(!empty($_POST['zapis'])){
$servername = "localhost";
$username = "test";
$password = "";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
}
?>
