Question

我正在努力让图片上传工作......

我有更多的表单元素，但我认为这是唯一重要的部分

<form name="register" method="post" action="profiles.php" onSubmit="return validateForm()">

        <td class="col1">Profile Picture</td>
         <td class="col2">
            <input type="file" name="file" id="file">
        </td>

将其传递给profiles.php

profiles.php包含传递的表单的所有变量....期望那个。我收到错误“通知：未定义的索引：文件”

这基本上是脚本中使用的所有文件......

    $target = "files/";

    echo $_FILES['file']['name'];
    //$image = basename($_FILES['file']['name']);
    //echo $image;
    $name = str_replace(' ', '_', $image);
    $target .= strtolower($name . uniqid());

    if(move_uploaded_file($_FILES['file']['tmp_name'], $target))
    {

    //echo $firstName, $lastName, $UserName, $email, $DOB, $join, $gender, $likes; 
//just a test to see if they were working.


addEntry($firstName, $lastName, $UserName, $Password, $email, $DOB, $join, $gender, $likes, $description, $newlike, $target);
    }

Answer 1

尝试将enctype =“multipart / form-data”添加到html表单标记中。即：

<form enctype="multipart/form-data">

Answer 2

enctype="multipart/form-data"中缺少<form>。

Answer 3

很可能您还没有在表单中定义文件上传元素“文件”。

<input type="file" name="file" id="file" />

另外，请确保您的表单enctype为"multipart/form-data"

<form action="upload.php" method="post" enctype="multipart/form-data">

Answer 4

兄弟enctype="multipart/form-data"

它不会通过变量？文件php
