多张图片上传 PHP 表单，一个输入

Question

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.

this is my 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

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.

Please I really need your expertise. THank you

Answer 1

extract($_POST);
$error=array();
$extension=array("jpeg","jpg","png","gif");
foreach($_FILES["files"]["tmp_name"] as $key=>$tmp_name) {
    $file_name=$_FILES["files"]["name"][$key];
    $file_tmp=$_FILES["files"]["tmp_name"][$key];
    $ext=pathinfo($file_name,PATHINFO_EXTENSION);

    if(in_array($ext,$extension)) {
        if(!file_exists("photo_gallery/".$txtGalleryName."/".$file_name)) {
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$file_name);
        }
        else {
            $filename=basename($file_name,$ext);
            $newFileName=$filename.time().".".$ext;
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$newFileName);
        }
    }
    else {
        array_push($error,"$file_name, ");
    }
}

and you must check your HTML code

<form action="create_photo_gallery.php" method="post" enctype="multipart/form-data">
    <table width="100%">
        <tr>
            <td>Select Photo (one or multiple):</td>
            <td><input type="file" name="files[]" multiple/></td>
        </tr>
        <tr>
            <td colspan="2" align="center">Note: Supported image format: .jpeg, .jpg, .png, .gif</td>
        </tr>
        <tr>
            <td colspan="2" align="center"><input type="submit" value="Create Gallery" id="selectedButton"/></td>
        </tr>
    </table>
</form>

Multiple Image upload using php full source code and preview available at the below Link.
Sample code:

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/>';
            } else { //if file was not moved.
                echo $j.
                ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else { //if file size and file type was incorrect.
            echo $j.

<?php
if(isset($_POST['btnSave'])){
    $j = 0; //Variable for indexing uploaded image 

    $file_name_all="";

    $target_path = "uploads/"; //Declaring Path for uploaded images

    //loop to get individual element from the array
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.)

        $target_path = $target_path .$basename;//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] < (1024*1024)) //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/>';
                /***********************************************/

                $file_name_all.=$target_path."*";  
                $filepath = rtrim($file_name_all, '*');  
                //echo"<img src=".$filepath."   >";          

                /*************************************************/
            } else {//if file was not moved.

            }
        } else {//if file size and file type was incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
    $qry="INSERT INTO `eb_re_about_us`(`er_abt_us_id`, `er_cli_id`, `er_cli_abt_info`, `er_cli_abt_img`) VALUES (NULL,'$b1','$b5','$filepath')";


    $res = mysql_query($qry,$conn); 
    if($res)
        echo "<br/><br/>Client contact Person Information Details Saved successfully";
        //header("location: nextaddclient.php");
        //exit();
    else
        echo "<br/><br/>Client contact Person Information Details not saved successfully";

}
?>

Here $file_name_all And $filepath get 1 uplode file name 2 time?

Multipal image uplode with other taBLE $sql1 = "INSERT INTO event(title) VALUES('$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 ){
                $name = $lastid.$_FILES['file']['name'][$key];
                $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

$query = "SELECT * FROM event ";
$result = mysqli_query($connection,$query) or die(mysqli_error());


  if($result->num_rows > 0) {
      while($r = mysqli_fetch_assoc($result)){
        $eventid= $r['id'];
        $sqli="select id,image from photos where eventid='".$eventid."'";
        $resulti=mysqli_query($connection,$sqli);
        $image_json_array = array();
        while($row = mysqli_fetch_assoc($resulti)){
            $image_id = $row['id'];
            $image_name = $row['image'];
            $image_json_array[] = array("id"=>$image_id,"name"=>$image_name);
        }
        $msg1[] = array ("imagelist" => $image_json_array);

      }

in ajax $(document).ready(function(){ $('#addCAT').validate({ rules:{name:required:true}submitHandler:function(form){var formurl = $(form).attr('action'); $.ajax({ url: formurl,type: "POST",data: new FormData(form),cache: false,processData: false,contentType: false,success: function(data) {window.location.href="{{ url('admin/listcategory')}}";}}); } })})
