Question

这是我的错误。我不知道为什么它不工作。我检查了所有的部分，但我无法找到错误。

注意：未定义的索引：第27行的C：\ xampp \ htdocs \ Final \ places \ Ressave.php中的图像

这是我传递输入名称的html代码：

<form class="form-horizontal" action="Ressave.php" method="POST" autocomplete="on">
<div class="well">
   <legend>Photos</legend>
      <div class="control-group">
         <label class="control-label">Upload Photo: </label>
             <div class="controls">
                   <input name="image" type="file" />
             </div>   
     </div>
</div>

            <div class="form-actions">

              <button type="submit" class="btn btn-primary">Submit</button>

              <button type="button" class="btn">Cancel</button>

            </div>

        </form>

Ressave.php就在这里，不能在这里收到名字，所以发生错误......

Answer 1

如果没有上传文件，$ _FILES数组将为空。具体而言，如果未上传文件image，则不会设置$_FILES['image']。

所以

$file = $_FILES['image']['tmp_name'];   //Error comes from here(here is the prob!)

应该是：

if(empty($_FILES) || !isset($_FILES['image']))

<强>更新

您还会遇到问题，因为您错过了表单上的enctype属性：

<form class="form-horizontal" action="Ressave.php" method="POST" autocomplete="on" enctype="multipart/form-data">

Answer 2

为了能够处理表单中的文件，您需要添加enctype属性。

<form method='POST' enctype='multipart/form-data' >

Answer 3

嘿，我想你已经忘记了形式中的一个重要设置 enctype =“multipart / form-data”当与文件一起使用时使用此选项，例如图像文件等

<form name="image" method="post" enctype="multipart/form-data">

除了提取文件内容之外，您还可以使用以下选项

$tmp_img_path = $_FILES['image']['tmp_name'];
$img_name = $_FILES['image']['name'];

打印文件的所有内容：

print_r($_POST['image']);

Answer 4

这是我成功将数据插入mysql并从数据库中检索的代码。

＆＃34;的index.php＆＃34;

<html>
<head>
<title>PHP & MySQL: Upload an image</title>
</head>
<body>
<form action="index.php" method="POST" enctype="multipart/form-data">
File: <input type="file" name="image" /><input type="submit" value="Upload" />
</form>

<?php
mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("registrations") or die(mysql_error());
if(!isset($_FILES['image']))
{
echo 'Please select an image.';
}
else {
$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
echo $_FILES['image']['tmp_name'];
$image_name = addslashes($_FILES['image']['name']);
$image_size = getimagesize($_FILES['image']['tmp_name']);

if($image_size==FALSE){
echo "That's not an image.";
} else {
if(!$insert = mysql_query("INSERT INTO test_image VALUES ('','$image_name','$image')"))
     {
 echo "Problem uploading image.";
 } else {
  $lastid = mysql_insert_id();
  echo "Image uploaded.<p />Your image:<p /><img src=get.php?id=$lastid>";
  }
}

  }
?>
</body>
</html>

这是get.PHP

<?php
mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("registrations") or die(mysql_error());
$id = addslashes($_REQUEST['id']);
$image = mysql_query("SELECT * FROM test_image WHERE id=$id");
$image = mysql_fetch_assoc($image);
$image = $image['image'];
header("Content-type: image/jpeg");
echo $image;
?>

注意： - 请相应更改您的数据库和表名称。谢谢， Santanu

注意：未定义索引：图像 - 无法找到错误
