我想在這裏做一些非常簡單的事情。我想要做的就是更新MySQL中的信息。 下面是表單的代碼。使用表格更新MySQL我的代碼不起作用
<?php
$host=""; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name=""; // Database name
$tbl_name=""; // Table name
// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// get value of id that sent from address bar
$dj=$_GET['dj'];
// Retrieve data from database
$sql="SELECT * FROM $tbl_name WHERE dj='$dj'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);
?>

<?php
// close connection
mysql_close();

現在我希望能夠做的是編輯當前的形式顯示數據庫中的信息。 (表單正在顯示來自mysql的正確信息) 如果我想改變讓我們說的電子郵件2我只是在現場這樣做,然後點擊提交。那麼我的問題是,當我這樣做時,我得到的只是錯誤。
所以,讓我們來看看我的update_ac.php 代碼如下:
<?php
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name=""; // Database name
$tbl_name=""; // Table name
// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// update data in mysql database
$sql="UPDATE currentdj SET name='$name',
email='$email',
email2='$email2',
twitter='$twitter',
twitter2='$twitter2',
avatar='$avatar',
facebook='$facebook',
facebook2='$facebook2',
type='$type',
alias1='$alias1',
alias2='$alias2',
alias3='$alias3',
address='$address'
WHERE dj='$dj'";
$result=mysql_query($sql);
// if successfully updated.
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='list_records.php'>View result</a>";
}
else {
echo "ERROR";
}
?>
我想知道如果我只是有一個語法,甚至這裏的拼寫問題! 任何幫助,將不勝感激。
謝謝!
你得到了什麼錯誤? –
所有的i得到的是簡單的錯誤,因爲這就是: 其他{ 回聲「ERROR」; } 在我update_ac.php – Feek
結束時,你忘了關'電子郵件='$ email'用單引號 –
