Multiple Image Upload PHP form with one input
提问by clvxc
I've been trying to make this work for quite some time now. But I can't seem to make it work. I wanted to have a multiple image upload form with only using one input.
一段时间以来，我一直在努力使这项工作发挥作用。但我似乎无法让它发挥作用。我想要一个只使用一个输入的多图像上传表单。
this is my upload.php
这是我的upload.php
<?php
include("../include/session.php");
session_start();
$allowedExts = array("jpeg", "jpg", "png", "gif");
$extension = end(explode(".", $_FILES["upload"]["name"]));
if(isset($_FILES['upload']['tmp_name']))
{
for($i=0; $i < count($_FILES['upload']['tmp_name']);$i++)
{
if (($_FILES["upload"]["name"] < 90000000000000000)
&& in_array($extension, $allowedExts)) {
if ($_FILES["upload"]["error"] > 0)
{
header('location: '.$error); die;
}
else
{
if (file_exists("../icons/".$_SESSION["username"] ."/" . $_FILES["upload"]["name"]))
{
echo "error";
}
else
{
if(!is_dir("../icons/". $_SESSION["username"] ."/")) {
mkdir("../icons/". $_SESSION["username"] ."/");
}
$temp = explode(".",$_FILES["upload"]["name"]);
$file = rand(1,999999999999) . '.' .end($temp);
move_uploaded_file($_FILES["upload"]["tmp_name"], "../icons/". $_SESSION["username"] ."/". $file);
}
}
}
} else {
echo "yep error";
}
}
}
?>
if i take out the lines
如果我取出线条
if(isset($_FILES['upload']['tmp_name']))
{
for($i=0; $i < count($_FILES['upload']['tmp_name']);$i++)
{
With the corresponding closing bracket, it seems to work fine. The image is uploaded perfectly. But the thing is, it only allows me to upload one.
使用相应的结束括号，它似乎工作正常。图片上传完美。但问题是，它只允许我上传一个。
Please I really need your expertise. THank you
请我真的需要你的专业知识。谢谢你

Multiple Image upload using php full source code and preview available at the below Link.
Sample code:
使用 php 完整源代码上传多张图片，并在以下链接中提供预览。
示例代码：
if (isset($_POST['submit'])) {
$j = 0; //Variable for indexing uploaded image
$target_path = "uploads/"; //Declaring Path for uploaded images
for ($i = 0; $i < count($_FILES['file']['name']); $i++) { //loop to get individual element from the array
$validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
$ext = explode('.', basename($_FILES['file']['name'][$i])); //explode file name from dot(.)
$file_extension = end($ext); //store extensions in the variable
$target_path = $target_path.md5(uniqid()).
".".$ext[count($ext) - 1]; //set the target path with a new name of image
$j = $j + 1; //increment the number of uploaded images according to the files in array
if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
&& in_array($file_extension, $validextensions)) {
if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) { //if file moved to uploads folder
echo $j.
').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';

Here $file_name_allAnd $filepathget 1 uplode file name 2 time?
这里 $file_name_all和$filepath得到 1 uplode 文件名 2 次？

Multipal image uplode with other taBLE $sql1 = "INSERT INTO event(title) VALUES('$title')";
多张图片与其他表格一起上传 $sql1 = "INSERT INTO event(title) VALUES('$title')";
$result1 = mysqli_query($connection,$sql1) or die(mysqli_error($connection));
$lastid= $connection->insert_id;
foreach ($_FILES["file"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK ){

$target_dir = "photo/";
$sql2 = "INSERT INTO photos(image,eventid) VALUES ('".$target_dir.$name."','".$lastid."')";
$result2 = mysqli_query($connection,$sql2) or die(mysqli_error($connection));
move_uploaded_file($_FILES['file']['tmp_name'][$key],$target_dir.$name);

And how to fetch
以及如何获取

$image_name = $row['image'];
$image_json_array[] = array("id"=>$image_id,"name"=>$image_name);
}
$msg1[] = array ("imagelist" => $image_json_array);
