[英]Insert data to database php error
Be kind, I am still learning, I have made this code but it didn't work, I have tried everything, it is suppose to when an user is logged in and someone send an image the member name is recorded at the database: 友善,我仍在学习,我编写了这段代码,但是没有用,我已经尝试了所有方法,这是假设当用户登录并向某人发送图像时,其成员名称记录在数据库中:
if (!isset($_SESSION[sforum_.'sforum_logged_in']));
if(isset($_SESSION[sforum_.'sforum_user_username'])) {
mysqli_query(INSERT INTO media (membro) VALUES ('$_SESSION[sforum_.'sforum_user_username']'));
} else {
Echo "erro";
}
It gives an error: 它给出了一个错误:
Parse error: syntax error, unexpected T_STRING
解析错误:语法错误,意外的T_STRING
You have 2 issues here. 您在这里有2期。 You need to quote your SQL in the query, and mysqli_query takes TWO parameters: the connection object link and the sql to run.
您需要在查询中引用SQL, mysqli_query带有两个参数:连接对象链接和要运行的sql。
mysqli_query($yourDbConnectionString, "INSERT INTO media (membro)
VALUES ('" . $_SESSION[sforum_ . 'sforum_user_username'] . "')");
Obviously substitute $yourDbConnectionString
with the actual value; 显然用实际值替换
$yourDbConnectionString
; you didn't include it in the code sample. 您没有将其包括在代码示例中。
Try this code 试试这个代码
<?php
if (!isset($_SESSION[sforum_ . 'sforum_logged_in'])) {
if (isset($_SESSION[sforum_ . 'sforum_user_username'])) {
mysqli_query("INSERT INTO media (membro) VALUES ('" . $_SESSION[sforum_ . 'sforum_user_username'] . "')");
} else {
echo "error";
}
}
?>
if(!isset($_SESSION['sforum_logged_in'])) ;
if(isset($_SESSION['sforum_user_username'])) {
$query = "INSERT INTO media(membro) VALUES (`" . $_SESSION['sforum_user_username'] . "`)";
mysqli_query($dbConnect, $query); //$dbConnect is database connected object
}
else {
echo "erro";
}
