php - 图片上传错误

Question

我想通过php上传图片到mysql数据库。我以前用它没有任何问题，但现在我不能。这是我的代码::

图片.php

 <form action='image2.php' method='POST' entype='multipart/form-data'>
    <b> Code :: </b> <input type='text' name='randomValue'>  <br />
      <b> Upload your image :: </b> <input type='file' name='image'> <br />
     <input type='submit' name='submitX' value='Complete Registration'>
 </form>

image2.php

 if(  isset($_POST['submitX'] ) )   {
     include('DB.php');

     $test = trim( addslashes( $_POST['randomValue'] ) );

     $image = addslashes( file_get_contents( $_FILES['image']['tmp_name'] ) );
     $size =  getimagesize( $_FILES['image']['tmp_name'] );

     if( $size > 0  ) {
        mysql_query(" INSERT INTO test VALUES ('' , '$test', '$image') ") or die(mysql_error());
     }

     }

     ?>

错误是::

 Warning: file_get_contents() [function.file-get-contents]: Filename cannot be empty in  E:\xampp\htdocs\MyWork\test\image2.php on line 8

  Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in E:\xampp\htdocs\MyWork\test\image2.php on line 9

Answer 1

表单上没有名称为 img_name 的元素，请在表单中将其更改为 image_name

  <b> Upload your image :: </b> <input type='file' name='image_name'> <br />

或

$_POST['image'] 在从帖子获取数据的代码中。

   $test = trim( addslashes( $_POST['img_name'] ) );

应该是

   $test = trim( addslashes( $_POST['name'] ) );
