我写了一个代码来上传特定位置的图像，并显示上传的图像计数。当我选择以下8张图片时，它将完美工作。但如果我选择10到20张图片，这个代码就不起作用了。我真的不知道为什么在选择最少的图像时它会起作用，而在选择更多的图像时却不起作用。请找到我的以下代码
storeimage.php
<?php
require_once 'pdoconnectionusingclass.php';
?>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Multiple File Ppload with PHP</title>
</head>
<body>
<form action="storeimagename.php" method="POST" enctype="multipart/form-data">
<div>
<select name="moviename">
<option value = "">---Select---</option>
<?php
try
{
$dbobj=new database();
$dbobj->openconnection();
$sql='select * from tbl_movie';
$query=$dbobj->getdata($sql);
if(isset($query))
{
foreach ($query as $row)
{
echo '<option value='.str_replace(' ','_', $row['movie_name']).'>'.$row['movie_name'].'</option>';
}
}
$dbobj->closeconnection();
}
catch(Exception $e)
{
echo $e->getMessage();
}
?>
</div>
<br/>
<div>
<input type="file" id="file" name="files[]" multiple="multiple" accept="image/*" />
<input type="submit" value="Upload!" />
</div>
</form>
</body>
</html>
storeimagename.php
<?php
require_once 'pdoconnectionusingclass.php';
$valid_formats = array("jpg", "png", "gif", "bmp");
$max_file_size = 1048576 *10; //100 kb
$path = "uploads/"; // Upload directory
$count = 0;
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){
// Loop $_FILES to exeicute all files
$total_image=count($_FILES['files']['name']);
$dbobj=new database();
$dbobj->openconnection();
for($i=0;$i<$total_image;$i++)
{
foreach ($_FILES['files']['name'] as $i => $name) {
if ($_FILES['files']['error'][$i] == 4) {
continue; // Skip file if any error found
}
if ($_FILES['files']['error'][$i] == 0) {
if ($_FILES['files']['size'][$i] > $max_file_size) {
$message[] = "$name is too large!.";
continue; // Skip large files
}
elseif( ! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats) ){
$message[] = "$name is not a valid format";
continue; // Skip invalid file formats
}
else{ // No error found! Move uploaded files
// echo $_FILES['files']['tmp_name'][$i];
// echo $_FILES['files']['name'][$i];
if(move_uploaded_file($_FILES["files"]["tmp_name"][$i], $path.$name))
{
$count++; // Number of successfully uploaded file
$gallery.=','.$name;
}
}
}
}
}
if(count==18)
{
$sql='insert into tbl_movie_gallery values((select movie_id from tbl_movie where movie_name='.str_replace('_',' ',$_POST['moviename']).')'.$gallery.');';
$dbobj->insertdata($sql);
}
//unset($_FILES['files']);
$dbobj->closeconnection();
}
?>
程序在执行此$total_image=count（$_FILES['FILES']['name']）时终止；行，如果我选择10到20个文件$total_image显示计数为0。有人能帮忙吗？这里的问题是什么？提前谢谢。
PHP有一个可以一次上传的最大文件量设置。默认值为20。您需要在php.ini文件中对此进行更改。
您要查找的设置是max_file_uploads
