无法使用 php 将图像存储到数据库中

Question

I am trying to upload an image in my database from HTML form. I have written the PHP code and I have an error message

     <form action="login.php" method="post" enctype="multipart/form-data">
         user<input type="text" name="user_name1"  required />
           password<input type="password" name="password1" required />
             Email<input type="email" name="email11" required />     
Upload any image you want<input type="file" name="image">
  <input  class="submit" type="submit" name="submit2" value="sign up"/>

            </form>

and this is the PHP code

  <?php

     if(array_key_exists('submit2',$_POST))
{

$user=$_POST['user_name1'];
$pass=$_POST['password1'];
$email=$_POST['email11'];
$image=addcslashes($_FILES['image']['tmp_name']);
$image_name=addcslashes($_FILES['image']['name']);
$image2=file_get_contents($image);
$image3=base64_encode($image2);
$query9="insert into login  values('$user','$pass','$email','$image3','$image_name')";
if(mysqli_query($conn,$query9))

echo "Insert is successful";

else

echo "Error ".$query9."<br>".mysqli_error($conn);



}

mysqli_close($conn);
?>      

This is the error I get after executing the code

Warning: addcslashes() expects exactly 2 parameters, 1 given in

Answer 1

You are using addcslashes which requires 2 parameters, the first being the string, and the second, a list of characters you want to escape.

I believe you want to use addslashes which will return your string with backslashes before characters that need to be escaped.
