php images upload does not work - php

I am trying to figure out why i am getting a bunch of errors when trying to upload multiple images
the input is <input type='file' name='file[]' multiple>
the check is:
if (!empty($_FILES['file'])){
if ($_FILES['file']['name'] != "") {
$count = 0;
foreach ($_FILES['file']['name'] as $filename) {
$allowed = array('jpg', 'jpeg', 'png', 'bmp', 'tiff', 'gif');
$img_name = $filename;
$img_extn = strtolower(end(explode('.', $img_name)));
$img_temp = $_FILES['file']['tmp_name'][$count];
$count = $count + 1;
if(in_array($img_extn, $allowed) === true){
$img_path = 'images/images/' . substr(md5(time()), 0, 10) . '.' . $img_extn;
move_uploaded_file($img_temp, $img_path);
$images = array(
'images' => $img_path,
'post_id' => $_POST['id']
);
add_images($images);
}else{
$errors[] = ''.$filename.' - file type is not allowed. Only: ' . implode(', ', $allowed) . '';
}
}
}
}
only one image is being uploaded to the temp folder
and how can i connect the post_id to the database?

Why don't you use $filename inside the foreach instead of $_FILES['file']['name']?

$img_name = $_FILES['file']['name'];
should be
$img_name = $filename;
since you are using for-each
foreach ($_FILES['file']['name'] as $filename) {
}

Multiple images. it has to be $_FILES['file']['name'][0]
Use indexes to access it. Since I see that you haven't used indexes. explode() throws a warning because it's trying to break an array.

PHP fileupload giving all filenames from array

I've been looking in this for a day or two now.
When I upload multiple files to this script, "$finalfilename" give's me back multiple filenames from the second file.
Here's my code:
include ($_SERVER['DOCUMENT_ROOT'] . "/config/config.php");
$valid_extensions = array(
'jpeg',
'jpg',
'png',
'gif',
'bmp'
); // valid extensions
$path = $_SERVER['DOCUMENT_ROOT'] . '/assets/uploads/'; // upload directory
$uploadOK = 1;
$album = strip_tags($_POST['newPostForm-Album']);
$i = 0;
foreach($_FILES['NEW-POST-FORM_IMAGES']['name'] as $file)
{
$imgname = $_FILES['NEW-POST-FORM_IMAGES']['name'][$i];
$tmpname = $_FILES['NEW-POST-FORM_IMAGES']['tmp_name'][$i];
$timestamp = time();
$extension = strtolower(pathinfo($imgname, PATHINFO_EXTENSION));
$newfilename = sha1(time() . $i);
$finalfilename = $newfilename . "." . $extension;
if ($_FILES['NEW-POST-FORM_IMAGES']["size"][$i] > 500000)
{
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
if ($uploadOK)
{
if (in_array($extension, $valid_extensions))
{
$path = $path . strtolower($finalfilename);
if (move_uploaded_file($tmpname, $path))
{
// mysqli_query($con, "INSERT INTO posts VALUES('', '$album', '$finalfilename', '$timestamp')");
echo $_FILES['NEW-POST-FORM_IMAGES']['name'][$i];
}
else
{
echo "error!";
}
}
}
$imgname = "";
$tmpname = "";
$timestamp = "";
$extension = "";
$newfilename = "";
$finalfilename = "";
$i++;
}
As you can see, I tried resetting all the strings at the end before adding $i.
UPDATE
I tried using $file instead of $_FILES (echo $file['name'][$i];)
This gives me back this warning:
Illegal string offset 'name' in
also the output of the second file ($finalfilename) gives me 'filename'.extention'filename'.extention
ea5816965b01dae0b19072606596c01efc015334.jpeg21aa3008f90c89059d981bdc51b458ca1954ab46.jpg
Wich need to be separated.
I need to only get the filename of each file seperatly.
Thank you!
Problem is in $path variable.
Put $path = $_SERVER['DOCUMENT_ROOT'] . '/assets/uploads/'; into the loop. You can remove variable reseting from the end too.
foreach ($_FILES['NEW-POST-FORM_IMAGES']['name'] as $file) {
$path = $_SERVER['DOCUMENT_ROOT'] . '/assets/uploads/';
$imgname = $_FILES['NEW-POST-FORM_IMAGES']['name'][$i];
$tmpname = $_FILES['NEW-POST-FORM_IMAGES']['tmp_name'][$i];
$timestamp = time();
$extension = strtolower(pathinfo($imgname, PATHINFO_EXTENSION));
$newfilename = sha1(time() . $i);
$finalfilename = $newfilename . "." . $extension;
if ($_FILES['NEW-POST-FORM_IMAGES']["size"][$i] > 500000)
{
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
if ($uploadOK)
{
if (in_array($extension, $valid_extensions))
{
$path = $path . strtolower($finalfilename);
if (move_uploaded_file($tmpname, $path))
{
// mysqli_query($con, "INSERT INTO posts VALUES('', '$album', '$finalfilename', '$timestamp')");
echo $_FILES['NEW-POST-FORM_IMAGES']['name'][$i];
}
else
{
echo "error!";
}
}
}
$i++;
}
There are more thing to update, instead of foreach for/while would be better here, or using foreach in else way (use $file in the loop body), etc. Moving $path into loop is easiest way how to fix your problem.

PHP uploading multiple images and inserting into them into database

i want to upload multiple images using this code but i can`t , i think it would be by using for each but every time i try the errors come everywhere
i want to insert the whole images paths in one column and after each picture ','
here is the php code
if (isset($_POST['upload_file'])) {
$date = date('Y-m-d h:i:s');
if ($_FILES['image']['name'] != '') {
$temp = explode('.', $_FILES['image']['name']);
$image_name = round(microtime(true)) . '.' . end($temp);
$image_tmp = $_FILES['image']['tmp_name'];
$image_size = $_FILES['image']['size'];
$image_ext = pathinfo($image_name,PATHINFO_EXTENSION);
$image_path = '../media/file/'.$image_name;
$image_db_path = '../media/file/'.$image_name;
if ($image_size < '50000000') {
if ($image_ext == 'jpg' || $image_ext == 'png' || $image_ext =='gif' || $image_ext == 'jpeg') {
if (move_uploaded_file($image_tmp, $image_path)) {
$ins_sql = "INSERT INTO files (imgs_paths, date) VALUES ('$image_db_path', '$date')";
if (mysqli_query($conn,$ins_sql)) {
header('Location: index.php');
}else{
$error = '';
}
}else{
$error = '';
}
}else{
$error = '';
}
}else{
$error = '';
}
} else{
$error = '';
}
}
and here the html code
<input type="file" accept="image/*" name="image[]" multiple/>
You're right about using foreach. If you need to upload multiple, you'll need to use it. And it's as simple as:
foreach($_FILES['image'] as $i => $file){
///... other code
$temp = explode('.', $_FILES['image'][$i]['name']);
$image_name = round(microtime(true)) . '.' . end($temp);
$image_tmp = $_FILES['image'][$i]['tmp_name'];
$image_size = $_FILES['image'][$i]['size'];
///... rest of code
}
Since it's an array of images, you need to access each element. Notice how we're using the array index($i) to access the current element in the loop.
As #RiggsFolly stated, you can also use $file in your loop as it is also the current element in the loop. (Instead of $_FILES['image'][$i]...)

get all the images from a folder in php

I am using WordPress. I have an image folder like mytheme/images/myimages.
I want to retrieve all the images name from the folder myimages
Please advice me, how can I get images name.
try this
$directory = "mytheme/images/myimages";
$images = glob($directory . "/*.jpg");
foreach($images as $image)
{
echo $image;
}
you can do it simply with PHP opendir function.
example:
$handle = opendir(dirname(realpath(__FILE__)).'/pictures/');
while($file = readdir($handle)){
if($file !== '.' && $file !== '..'){
echo '<img src="pictures/'.$file.'" border="0" />';
}
}
When you want to get all image from folder then use glob() built in function which help to get all image . But when you get all then sometime need to check that all is valid so in this case this code help you. this code will also check that it is image
$all_files = glob("mytheme/images/myimages/*.*");
for ($i=0; $i<count($all_files); $i++)
{
$image_name = $all_files[$i];
$supported_format = array('gif','jpg','jpeg','png');
$ext = strtolower(pathinfo($image_name, PATHINFO_EXTENSION));
if (in_array($ext, $supported_format))
{
echo '<img src="'.$image_name .'" alt="'.$image_name.'" />'."<br /><br />";
} else {
continue;
}
}
If you do not want to check image type then you can use this code also
$all_files = glob("mytheme/images/myimages/*.*");
for ($i=0; $i<count($all_files); $i++)
{
$image_name = $all_files[$i];
echo '<img src="'.$image_name .'" alt="'.$image_name.'" />'."<br /><br />";
}

PHP Manual
Here is my some code
$dir = '/Images';
$ImagesA = Get_ImagesToFolder($dir);
print_r($ImagesA);
function Get_ImagesToFolder($dir){
$ImagesArray = [];
$file_display = [ 'jpg', 'jpeg', 'png', 'gif' ];
if (file_exists($dir) == false) {
return ["Directory \'', $dir, '\' not found!"];
}
else {
$dir_contents = scandir($dir);
foreach ($dir_contents as $file) {
$file_type = pathinfo($file, PATHINFO_EXTENSION);
if (in_array($file_type, $file_display) == true) {
$ImagesArray[] = $file;
}
}
return $ImagesArray;
}
}
This answer is specific for WordPress:
$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );
$media_dir = $base_dir . 'yourfolder/images/';
$media_url = $hase_url . 'yourfolder/images/';
$image_paths = glob( $media_dir . '*.jpg' );
$image_names = array();
$image_urls = array();
foreach ( $image_paths as $image ) {
$image_names[] = str_replace( $media_dir, '', $image );
$image_urls[] = str_replace( $media_dir, $media_url, $image );
}
// --- You now have:
// $image_paths ... list of absolute file paths
// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg
// $image_urls ... list of absolute file URLs
// e.g. http://example.com/wp-content/uploads/yourfolder/images/sample.jpg
// $image_names ... list of filenames only
// e.g. sample.jpg
Here are some other settings that will give you images from other places than the child theme. Just replace the first 2 lines in above code with the version you need:
From Uploads directory:
// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg
$upload_path = wp_upload_dir();
$base_dir = trailingslashit( $upload_path['basedir'] );
$base_url = trailingslashit( $upload_path['baseurl'] );
From Parent-Theme
// e.g. /path/to/wordpress/wp-content/themes/parent-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_template_directory() );
$base_url = trailingslashit( get_template_directory_uri() );
From Child-Theme
// e.g. /path/to/wordpress/wp-content/themes/child-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );
$dir = "mytheme/images/myimages";
$dh = opendir($dir);
while (false !== ($filename = readdir($dh))) {
$files[] = $filename;
}
$images=preg_grep ('/\.jpg$/i', $files);
Very fast because you only scan the needed directory.
//path to the directory to search/scan
$directory = "";
//echo "$directory"
//get all files in a directory. If any specific extension needed just have to put the .extension
//$local = glob($directory . "*");
$local = glob("" . $directory . "{*.jpg,*.gif,*.png}", GLOB_BRACE);
//print each file name
echo "<ul>";
foreach($local as $item)
{
echo '<li>'.$item.'</li>';
}
echo "</ul>";
Check if exist, put all files in array, preg grep all JPG files, echo new array For all images could try this:
$images=preg_grep('/\.(jpg|jpeg|png|gif)(?:[\?\#].*)?$/i', $files);
if ($handle = opendir('/path/to/folder')) {
while (false !== ($entry = readdir($handle))) {
$files[] = $entry;
}
$images=preg_grep('/\.jpg$/i', $files);
foreach($images as $image)
{
echo $image;
}
closedir($handle);
}
<?php
$galleryDir = 'gallery/';
foreach(glob("$galleryDir{*.jpg,*.gif,*.png,*.tif,*.jpeg}", GLOB_BRACE) as $photo)
{echo "\n" ;echo "<img style=\"padding:7px\" class=\"uk-card uk-card-default uk-card-hover uk-card-body\" src=\"$photo\">"; echo "";}?>

You can simply show your actual image directory(less secure). By just 2 line of code.

PHP images from directory - Random order

I have a page of my website which I use to store reference images..
Currently I just drop all of the images into a directory on my server and the php displays them how I like.
What i'd like to ask is how to I get them to display in a different random order every time the page is refreshed?
code is below:
$dir = 'images';
$file_display = array ('jpg', 'jpeg', 'png', 'gif');
if (file_exists($dir) ==false) {
echo 'Directory \'', $dir, '\' not found';
} else {
$dir_contents = scandir($dir);
foreach ($dir_contents as $file) {
$file_type = strtolower(end(explode('.', $file)));
if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true) {
echo '<img class="photo" src="', $dir, '/', $file, '" alt="', $file, '" />';
}
}
}
To guarantee that the order is different every time requires that you carry the data about the order in which they were displayed between page loads. However, this is not necessarily what you require - if you simply randomise the order every time then the higher the number of images in the directory the lower the chance you will get the same order twice.
You can simply use shuffle() to randomise the order of the array:
$dir = 'images';
$file_display = array ('jpg', 'jpeg', 'png', 'gif');
if (file_exists($dir) == false) {
echo 'Directory \'', $dir, '\' not found';
} else {
$dir_contents = scandir($dir);
shuffle($dir_contents);
foreach ($dir_contents as $file) {
$file_type = strtolower(end(explode('.', $file)));
if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true) {
echo '<img class="photo" src="', $dir, '/', $file, '" alt="', $file, '" />';
}
}
}
Look at shuffle function. http://php.net/manual/en/function.shuffle.php Since PHP is stateless, you'll either rescan your directory each time or assign the $dir_contents to a session variable. Then you could simple shuffle the session variable.
if ($file !== '.' && $file !== '..' && in_array($file_type, suffle($file_display)) == true) {
Try that.
Use php shuffle to the array of images created by scandir
$dir = 'images';
$file_display = array ('jpg', 'jpeg', 'png', 'gif');
if (file_exists($dir) == false) {
echo 'Directory \'', $dir, '\' not found';
} else {
$dir_contents = scandir($dir);
if(shuffle($dir_contents)) {
foreach ($dir_contents as $file) {
$info = new SplFileInfo($file);
// scandir returns an array of files and,or directories
// so we should check if $file is a file
// and that it's extension matches the allowed ones
// which are ('jpg', 'jpeg', 'png', 'gif')
if(is_file($file) && in_array($info->getExtension(),$file_display)) {
echo '<img class="photo" src="', $dir, '/', $file, '" alt="', $file, '" />';
}
}
} else {
echo 'Error applying random order!';
}
}
Please, follow this instruction: create a folder "php" into root of your website and put inside the following php file rotate.php... now create a folder "pic" and "xmas" into your root... you can chose the folder name or other things by editing the var $my_folder_holiday and $my_folder_default...

The usage is very easy and works very well under PHP 7.4... if you have in the root of your website a folder "pic" and "xmas" containing your images, please, put into your index.php (or other file php located in the root):
<img src="/<?php echo $my_gallery; ?>" alt="Random Gallery" width="90" height="67">
This is another usage using FancyBox library:
Hope this helps...

How to get random image from directory using PHP

I have one directory called images/tips.
Now in that directory I have many images which can change.
I want the PHP script to read the directory, to find the images, and out of those images found to pick a random image.
Any idea on how to do this?
$imagesDir = 'images/tips/';
$images = glob($imagesDir . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);
$randomImage = $images[array_rand($images)]; // See comments
You can send a 2nd argument to array_rand() to get more than 1.
$images = glob('images/tips/*');
return $images[rand(0, count($images) - 1)];
However, this doesn't ensure that the same image isn't picked twice consecutively.
<?php
foreach (glob("gallery/*") as $filename) {
echo '<li><img src="'.$filename.'" alt="" /> </li>';
}
?>
Look at this code, use it definitely if useful for you. It loads all files from folder and prints them in above format. I made this code to use with lightbox.
function get_rand_img($dir)
{
$arr = array();
$list = scandir($dir);
foreach($list as $file)
{
if(!isset($img))
{
$img = '';
}
if(is_file($dir . '/' . $file))
{
$ext = end(explode('.', $file));
if($ext == 'gif' || $ext == 'jpeg' || $ext == 'jpg' || $ext == 'png' || $ext == 'GIF' || $ext == 'JPEG' || $ext == 'JPG' || $ext == 'PNG')
{
array_push($arr, $file);
$img = $file;
}
}
}
if($img != '')
{
$img = array_rand($arr);
$img = $arr[$img];
}
$img = str_replace("'", "\'", $img);
$img = str_replace(" ", "%20", $img);
return $img;
}
echo get_rand_img('images');
replace 'images' with your folder.
Agreed with alexa.
Use simple function.
function RandImg($dir)
{
$images = glob($dir . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);
$randomImage = $images[array_rand($images)];
return $randomImage;
}
$the_image = RandImg('images/tips/');
echo $the_image;
$folder = "images";
$results_img_arr = array();
if (is_dir($folder))
{
if ($handle = opendir($folder))
{
while(($file = readdir($handle)) !== FALSE)
{
if(!in_array($file,array(".","..")))
$results_img_arr[] = $folder."/".$file;
}
closedir($handle);
}
}
$ran_img_key = array_rand($results_img_arr);
$img_path = $results_img_arr[$ran_img_key];
You can use opendir() to read in the filenames from that directory, storing each filename in an array. Then use rand() with a min and max corresponding to your array keys to select an item from the array.
Simpler:
$directory = "medias/photos/";
$img = glob($directory . "*.jpg");
shuffle($img);
I wrote a simple php script for my personal use. Now I want share it with stackoverflow's community. Usage is simple: create a folder "php" into root of your Web Server and put inside this file php rotate.php... now create two folders into your root called "pic" and "xmas"... you can adjust the folder names by editing the var $my_folder_holiday and $my_folder_default...

} else {

}
?>
This script was tested under PHP 7.0/7.1/7.2/7.3 and PHP 7.4 and works fine. Usage (for example in root you may have a folder "pic" and "xmas" containing your images):
<img src="/<?php echo $my_gallery; ?>" alt="Random Gallery" width="90" height="67">
Other usage using FancyBox library:
Hope this Helps.
Load folder with images:
$folder = opendir(images/tips/);
Build table out of files/images from directory:
$i = 0;
while(false !=($file = readdir($folder))){
if($file != "." && $file != ".."){
$images[$i]= $file;
$i++;
}
}
Pick random:
$random_img=rand(0,count($images)-1);
Show on page:
echo '<img src="images/tips'.$images[$random_img].'" alt="" />';
Hope it helps. Of course enclose it in <?php ?>.
