Question

我想制作一个简单的图片上传器。

我有两页＆＃39; index.html＆＃39;和＆＃39; upload.php＆＃39;

以下是index.html的代码

<html>
<head>

<script>

$(document).ready(function(){
$("#im").click(function() {
    $("input[id='my_file']").click();
});
$("#su").click(function() {
    $("input[id='submit']").click();
});    
});
    </script>       
</head>


    <body>

    <form method="post" action="upload.php" >
        <img  id="im" src="pic.png" width="30" height="30" />
        <img   id="su"    src="sent.png" width="50" height="50" />
        <input type="file" id="my_file" style="display: none;" name="img" />
        <input type="submit" id="submit"  style="display: none;" value="Upload Image" name="submit"/> 
    </form>

以下是upload.php的代码：

<?php

$target_path = "uploads/"; 
$target_path = $target_path . basename( $_FILES['img']['name']); 

if(move_uploaded_file($_FILES['img']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['img']['name']). 
    " has been uploaded";
} else{
    echo "fail : ". $_FILES['img']['error'] ;
}  

?>

我也创建了dir上传，我检查了它是否可写，确实如此。我编辑了php.ini并启用了上传并将最大大小提高到50米

当我上传文件时，它会显示：＆＃34;失败：＆＃34;

Answer 1

如果您有用于上传文件的表单，则需要将enctype='multipart/form-data'属性添加到表单。

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

尝试使用这个：PHP代码

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
?>

为什么我不能上传这个PHP代码？
