我有一个上传脚本，就像一个魅力，但我想扩展它不仅上传一个图像，而是几个图像。这导致我的脚本只上传最后一张图片而不是所有这些图片都包含在textarea中的文字。我无法弄清楚为什么它不会上传所有图片。
我的upload.php：
<?php // Start a session for error reporting session_start(); // Call our connection file require( "includes/conn.php"); // Check to see if the type of file uploaded is a valid image type function is_valid_type($file) { // This is an array that holds
all the valid image MIME types $valid_types=a rray( "image/jpg", "image/jpeg", "image/bmp", "image/gif"); if (in_array($file[ 'type'], $valid_types)) return 1; return 0; } // Just a short function that prints out the contents of an array in a manner that 's easy to read
// I used this function during debugging but it serves no purpose at run time for this example
function showContents($array)
{
echo "<pre>";
print_r($array);
echo "</pre>";
}
// Set some constants
// This variable is the path to the image folder where all the images are going to be stored
// Note that there is a trailing forward slash
$TARGET_PATH = "content/uploads/";
// Get our POSTed variables
$fname = $_POST['fname '];
$lname = $_POST['lname '];
$image = $_FILES['image '];
// Sanitize our inputs
$fname = mysql_real_escape_string($fname);
$lname = mysql_real_escape_string(nl2br($lname));
$image['name '] = mysql_real_escape_string($image['name ']);
// Build our target path full string. This is where the file will be moved do
// i.e. images/picture.jpg
$TARGET_PATH .= $image['name '];
// Make sure all the fields from the form have inputs
if ( $fname == "" || $lname == "" || $image['name '] == "" )
{
$_SESSION['error '] = "All fields are required";
header("Location: indexbackup.php");
exit;
}
// Check to make sure that our file is actually an image
// You check the file type instead of the extension because the extension can easily be faked
if (!is_valid_type($image))
{
$_SESSION['error '] = "You must upload a jpeg, gif, or bmp";
header("Location: indexupload.php");
exit;
}
// Here we check to see if a file with that name already exists
// You could get past filename problems by appending a timestamp to the filename and then continuing
if (file_exists($TARGET_PATH))
{
$_SESSION['error '] = "A file with that name already exists";
header("Location: indexupload.php");
exit;
}
// Lets attempt to move the file from its temporary directory to its new home
if (move_uploaded_file($image['tmp_name '], $TARGET_PATH))
{
// NOTE: This is where a lot of people make mistakes.
// We are *not* putting the image into the database; we are putting a reference to the file's location on the server $sql="insert into people (fname, lname, filename) values ('$fname', '$lname', '" . $image[ 'name'] . "')"; $result=m ysql_query($sql)
or die ( "Could not insert data into DB: " . mysql_error()); header( "Location: indexupload.php"); exit; } else { // A common cause of file moving failures is because of bad permissions on the directory attempting to be written to // Make sure you chmod
the directory to be writeable $_SESSION[ 'error']="Could not upload file. Check read/write persmissions on the directory" ; header( "Location: indexupload.php"); exit; } ?>
这是让我选择文件并填写文字区域的页面：
var abc = 0; // Declaring and defining global increment variable.
$(document).ready(function () {
// To add new input file field dynamically, on click of "Add More Files" button below function will be executed.
$('#add_more').click(function () {
$(this).before($("<div/>", {
id: 'filediv'
}).fadeIn('slow').append($("<input/>", {
name: 'image',
type: 'file',
id: 'file'
}), $("<br/><br/>")));
});
// Following function will executes on change event of file input to select different file.
$('body').on('change', '#file', function () {
if (this.files && this.files[0]) {
abc += 1; // Incrementing global variable by 1.
var z = abc - 1;
var x = $(this).parent().find('#previewimg' + z).remove();
$(this).before("<div id='abcd" + abc + "' class='abcd'><img id='previewimg" + abc + "' src=''/></div>");
var reader = new FileReader();
reader.onload = imageIsLoaded;
reader.readAsDataURL(this.files[0]);
$(this).hide();
$("#abcd" + abc).append($("<img/>", {
id: 'img',
src: 'images/x.png',
alt: 'delete'
}).click(function () {
$(this).parent().parent().remove();
}));
}
});
// To Preview Image
function imageIsLoaded(e) {
$('#previewimg' + abc).attr('src', e.target.result);
}
;
$('#upload').click(function (e) {
var name = $(":file").val();
if (!name) {
alert("First Image Must Be Selected");
e.preventDefault();
}
});
});<div id="maindiv">
<div id="formdiv">

if (isset($_SESSION['error'])) {
echo "<span id=\"error\"><p>" . $_SESSION['error'] . "</p></span>";
unset($_SESSION['error']);
}

先谢谢你们！

您的帖子参数的全部中有空格：
$fname = $_POST['fname '];
^--
该空间可用于命名目的，与'fname'不同。 _POST / _GET中的键必须与html中的键完全匹配：
<input type="text" name="foo"> -> $_POST['foo'] // note the LACK of a space
<input type="text" name="bar "> -> $_POST['bar '] // note the space
