Question

我正在尝试使用来自会话变量的用户的user_id将上传的图像插入到mysql中。我找到了一个在线教程并将其更改如下：

<?php
require_once('../Login/includes/session_timeout_db.inc.php');
$dbuser="";
  $dbname="";
  $dbpass="";
  $dbserver="";

  $con = mysql_connect($dbserver,$dbuser,$dbpass);
  if (!$con){ die('Could not connect: ' . mysql_error()); }
  mysql_select_db($dbname, $con);

  // Make sure the user actually
    // selected and uploaded a file
    if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) {

    // Temporary file name stored on the server
    $tmpName = $_FILES['image']['tmp_name'];

    // Read the file
    $fp = fopen($tmpName, 'r');
    $data = fread($fp, filesize($tmpName));
    $data = addslashes($data);
    fclose($fp);


    // Create the query and insert
    // into our database.
    $query = "INSERT INTO images, owner_id";
    $query .= "(image) VALUES ('$data', '.$_SESSION['id'].')";
    $results = mysql_query($query, $link);

// Print results
print "Thank you, your file has been uploaded.";

}
else {
print "No image selected/uploaded";
}

// Close our MySQL Link
mysql_close($link);
?>

<?php
require('../Login/includes/header.inc.php');
?>

<div id="content">
<form enctype="multipart/form-data" action="" method="post" name="changer">
<input name="MAX_FILE_SIZE" value="102400" type="hidden">
<input name="image" accept="image/jpeg" type="file">
<input value="Submit" type="submit">
</form>
</div>

</body>
</html>

我在查询的第二行有错误和错误：

$query = "INSERT INTO images, owner_id";
$query .= "(image) VALUES ('$data', '.$_SESSION['id'].')";
$results = mysql_query($query, $link);

*错误是Parse错误：语法错误，意外T_ENCAPSED_AND_WHITESPACE，在第28行期待T_STRING或T_VARIABLE或T_NUM_STRING *

有人可以帮忙吗？

Answer 1

您的images字段必须是BLOB类型。不要这样做，将文件保存在文件系统中，并将目录路径保存到数据库中的图像。

Answer 2

改变：

"(image) VALUES ('$data', '.$_SESSION['id'].')";

进入：

"(image) VALUES ('$data', '".$_SESSION['id']."')";

使用php将图像插入mysql
