Question

我已经在一个项目工作了很长一段时间，我正在开发的系统的一个主要功能是文件上传，我设置它以便将图像存储在文件名存储的目录中在数据库/这一切都工作正常但我今天正在运行的东西，我的文件上传突然不再工作，我不知道为什么？

如果有人能够对我的错误有所了解，那将非常感激！

文件上传功能（基于W3Schools的示例）

function upload_file(){
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["page_main_image"]["name"]);
$extension = end($temp);
if ((($_FILES["page_main_image"]["type"] == "image/gif")
        || ($_FILES["page_main_image"]["type"] == "image/jpeg")
        || ($_FILES["page_main_image"]["type"] == "image/jpg")
        || ($_FILES["page_main_image"]["type"] == "image/pjpeg")
        || ($_FILES["page_main_image"]["type"] == "image/x-png")
        || ($_FILES["page_main_image"]["type"] == "image/png"))
    && ($_FILES["page_main_image"]["size"] < 200000)
    && in_array($extension, $allowedExts))
{
    if ($_FILES["page_main_image"]["error"] > 0) {
        echo "Return Code: " . $_FILES["page_main_image"]["error"] . "<br />";;
    }
    else {
        echo "Upload: " . $_FILES["page_main_image"]["name"] . "<br />";
        echo "Type: " . $_FILES["page_main_image"]["type"] . "<br />";
        echo "Size: " . ($_FILES["page_main_image"]["size"] / 1024) . " kb<br />";

        if (file_exists("uploads/" . $_FILES["page_main_image"]["name"]))
        {
            echo $_FILES["page_main_image"]["name"] . " already exists. ";
        }
        else
        {
            move_uploaded_file($_FILES["page_main_image"]["tmp_name"],
                "uploads/" . $_FILES["page_main_image"]["name"]);
            echo "Stored in: " . "uploads/" . $_FILES["page_main_image"]["name"] . "<br />";
            $image="{$_FILES['page_main_image']['name']}";
        }
    }
}
else {
    echo "Invalid file";
}

return $image;
}

表格处理如下：

<?php
if (isset($_POST['submit'])) {
//Process the form
$image = upload_file();

$project_id = $_POST['project_id'];
//var_dump ($project_id);

$wireframe_title = mysql_prep($_POST["wireframe_title"]);
$browser_title = $_POST["browser_title"];
$url_key = $_POST["url_key"];
$wireframe_type = $_POST["wireframe_type"];
//$image = $_POST["page_main_image"];
$page_bg_color = $_POST ["page_bg_color"];

$query  = "INSERT INTO wireframes (";
$query .= " project_id, wireframe_title, browser_title, url_key, wireframe_type, page_main_image, page_bg_color";
$query .= " ) VALUES (";
$query .= " '{$project_id}','{$wireframe_title}', '{$browser_title}', '{$url_key}', '{$wireframe_type}', '{$image}', '{$page_bg_color}' ";
$query .= ")";

echo $query;

try { $result = mysqli_query($connection, $query);
} catch (Exception $e) {
    return 'Caught exception: '+  $e->getMessage()+ "\n";
}
//Test if there was a query error
if ($result) {
    //Success
    // would normally use a redirect ie redirect_to("somepage.php");
    //$message = "Subject created.";
    redirect_to("wireframes.php?id=$project_id");
}else {
    //failure
    //$message = "Subject creation failed.";
    //redirect_to("add_project.php");
    echo $query;
}
} else {
// This is probably a GET request
redirect_to("add_edit_wireframe.php?id= echo $_GET[$project_id]");
}
?>

我完全不知道为什么它突然停止了我周六只使用了图片上传而且工作正常并且从那时起就没有触及它。

编辑：由于某种原因，它可以作为更新，它允许我上传某些图像而不是其他图像。可能是由于文件大小？我已经在php.ini文件中将max_upload大小更改为4mb，但这没有帮助。有没有办法测试这个？

我注意到我在用于处理文件上传的函数中，它在开始时将大小设置为＆lt; 200000然后再向下它有大小/ 1024 kb

有人可以向我解释这个，所以我明白究竟发生了什么，如果我知道这可能我可以更改数字以允许上传更大的文件？
