Question

我已经增加了文件大小。但是仍然不起作用，我想添加这些代码中的任何一个，并在文件可访问的情况下增加文件的大小...

MySQL 5，PHP 5

$permited  = array('jpg', 'jpeg', 'png', 'gif');
$file_name = $_FILES['image']['name'];
$file_size = $_FILES['image']['size'];
$file_temp = $_FILES['image']['tmp_name'];

$div = explode('.', $file_name);
$file_ext = strtolower(end($div));
$unique_image = substr(md5(time()), 0, 10) . '.' . $file_ext;
$uploaded_image = "upload/" . $unique_image;


if ($title == "" || $cat == "" || $body == "" || $tags == "") {
    echo "<span class='error'> Must be Fill</span>";
} else {
    if (!empty($file_name)) {
        if ($file_size > 50048567) {


            echo "<span class='error'>Image Size should be less then 1MB!
    </span>";
        } elseif (in_array($file_ext, $permited) === false) {
            echo "<span class='error'>You can upload only:-"
                . implode(', ', $permited) . "</span>";
        } else {
            move_uploaded_file($file_temp, $uploaded_image);
            $query = "UPDATE  tbl_post
        SET

您的代码对我来说不错，但是您可以在下面尝试这种方法，以检查上传时是否有错误。

<?php

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["image"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if (isset($_POST["submit"])) {
    $check = getimagesize($_FILES["image"]["tmp_name"]);
    if ($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["image"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if ($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif") {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)) {
        echo "The file ". basename($_FILES["image"]["name"]). " has been uploaded.";
    // do you sql query
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
