注意:未定义索引:图像 - 无法找到错误 [英] Notice: Undefined index: image - unable to find the error

问题描述

这是我的错误.我不知道为什么它不起作用.我检查了所有部分，但我找不到错误.

<块引用>

注意:未定义索引:第 27 行 C:\xampp\htdocs\Final\places\Ressave.php 中的图像

这是我传递输入名称的html代码:

<div class="well"><legend>照片</legend><div class="control-group"><label class="control-label">上传照片:</label><div class="控件"><input name="image" type="file"/>

<div class="form-actions"><button type="submit" class="btn btn-primary">提交</button><button type="button" class="btn">取消</button>

</表单>

Ressave.php 在这里，无法在这里接收名称，所以出现错误......

解决方案

如果文件没有上传，$_FILES 数组将为空.具体来说，如果文件 image 没有上传，$_FILES['image'] 将不会被设置.

所以

$file = $_FILES['image']['tmp_name'];//错误来自这里(这里是问题！)

应该是:

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

更新

您也会遇到问题，因为您缺少表单上的 enctype 属性:

here is my error.i dont know why it is not working.i checked all the parts but i was unable to find the error.

Notice: Undefined index: image in C:\xampp\htdocs\Final\places\Ressave.php on line 27

here is my html code that pass the name of input:

<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 is here and can not recieve the name here,so the error occure.....

mysql_close($dbConnected);
?>

解决方案

If a file was not uploaded the $_FILES array will be empty. Specifically, if the file image was not uploaded, $_FILES['image'] will not be set.

So

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

should be:

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

update

You will also have issues because you're missing the enctype attribute on your form:

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