I have a piece of code to upload a picture and save it in a folder and the path in a databaseand show it on the webpage. Funny enough, upon uploading the picture for the first time, the image will show on the webpage and with change when I upload a new picture. But when I close the page, reopen it another day and decide to change the picture, the one of the webpage won't change even if i refresh the page but the one in the folder will change.
Here's my code
<?php
$sql2 = "SELECT Picture_HD FROM detailss WHERE Idn_nom = '$Indnum'";
require('connect.php');
$addr = "";
$addr = mysqli_query($conn, $sql2);
if ($addr) {
$locat = $addr->fetch_row();
$locat = (string)$locat[0];
} else {
$locat = "Pictures/default1.png";
}
mysqli_close($conn);
echo "<div id = 'Img'>";
echo "<img src = '" . $locat . "' alt = 'Passport picture/Headshot' style = 'width:80px; height:80px;'/>";
echo "</div>";
?>
Your browser is caching the image.
If you want to prevent the browser to cache the image just add a random parameter at the end of the url.
echo "<img src = '" . $locat . "?t=" . time() . "' alt = 'Passport picture/Headshot' style = 'width:80px; height:80px;'/>";
If your image is changing in your folder but you are seeing the old one on the webpage it's likely a caching issue, clear your browser cache (ctrl+f5 plus this is kinda broken so doesn't always work - so best to go into browser settings to do it, or open a private window after ctrl+f5) and if not the clear server level cache.
The best way to do this is to delete the existing image right before uploading the new one with the same file name
// define variables used for file name from session variable username the directory and extension by exploding the file name from the post method from a form with a metadata type
//set new file name to username from session variable
$filename = $_SESSION['username']
// set directory of files
$dir = "img/";
// set extension variable to file extension after posted from form
$ext=strtolower(end(explode('.',$_FILES['importimg']['name'])));
// new file upload name with existing extension
$upload_file = $dir . $filename . "." . $ext;
// delete file
// find all files with the same name any extension using variable defined above etc .txt, .php, .gif, .jpg, etc. then delete it
foreach (glob("img/$filename.*") as $deletefile) {
// unlink is used to delete the file and delete the cache of the file
unlink($deletefile);
}
// upload image
// upload file with type posted from metadata in form and upload it as your new file name using upload_file variable
if (move_uploaded_file($_FILES['importimg']['tmp_name'], $upload_file)) {
// successful upload of file add code for msg or sql query etc name to users table and redirect to profile page
echo "Successfully uploaded your file.";
} else {
// upload error show message
echo "There was an error uploading your file.";
}

I want to be able to upload images from my Windows Phone 8 app, to my website.
For this, I followed the tutorial from this website:
https://vortexwolf.wordpress.com/2013/06/04/windows-phone-select-and-upload-image-to-a-website-over-http-post/
It all worked good, on the windows phone app side. But I have problems getting the website upload.php file working. In that tutorial, the author is using http://posttestserver.com/post.php?dir=wp7posttest to get the response of upload. In my case, using that URL for testing was working good, but when I put my website url, I get no response, and a crash in visual studio, with following error:
Additional information: The remote server returned an error: NotFound.
This error happens is thrown on this line:
response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
The upload.php on my website, looks like this:
if(isset($_GET['dir']))
{
$dir = $_GET['dir'];
if($_FILES['photo']['name'])
{
if(!$_FILES['photo']['error'])
{
$new_file_name = strtolower($_FILES['photo']['tmp_name']);
if($_FILES['photo']['size'] > (1024000))
{
$valid_file = false;
$message = 'Oops! Your file\'s size is to large.';
}
if($valid_file)
{
move_uploaded_file($_FILES['photo']['tmp_name'], '../$dir/' . $new_file_name);
$message = 'Congratulations! Your file was accepted.';
}
}
else
{
$message = 'Ooops! Your upload triggered the following error: '.$_FILES['photo']['error'];
}
}
echo $message;
}
I am out of ideas, and stuck on this problem for the second day. Any answers/ideas of how to get the website upload.php file working properly?
Thanks!
I am new for developing.I have opted for php to learn coding.So I might make mistake as I learn by myself, kindly clarify my doubts.
I have problem in uploading files using php to a folder.What I really do is, I upload a file and the file is saved in a folder and the name of the file alone inserted in the database. While uploading the file I do copy the file to another folder which will be used for the editing purpose so that the original file will not be disturbed.Here the problem I get is, the file is uploaded successfully as well as the name too inserted in database. But it take much time to get upload even the size of the file is small.It works good while I test using my local but when I come in real time this issue(slow uploading) I face. What the person incharge in uploading do is, uploading a file and opening a new browser and upload another file. When the new browser is opened the files get uploaded but in the previous browser it is still in process. The code I have written to copy the file to another folder is not executed as the new browser is opened to upload another set of files. I am using xamp cp v3.2.1.To minimize the execution time I have set the default Maximum execution time to 30. But unable to upload file fastly.
Below is my php coding:
<?php
// connect to the database
include('connect-db.php');
if (isset($_POST['submit']))
{
// get form data, making sure it is valid
$udate = mysql_real_escape_string(htmlspecialchars($_POST['udate']));
$file_array=($_FILES['file_array']['name']);
// check to make sure both fields are entered
if ($udate == '' || $file_array=='')
{
// generate error message
$error = 'ERROR: Please fill in all required fields!';
// if either field is blank, display the form again
renderForm($udate, $file_array, $error);
}
else
{
$udate = mysql_real_escape_string(htmlspecialchars($_POST['udate']));
if(isset($_FILES['file_array']))
{
$name_arrray=$_FILES['file_array']['name'];
$tmp_name_arrray=$_FILES['file_array']['tmp_name'];
for($i=0;$i <count($tmp_name_arrray); $i++)
{
if(move_uploaded_file($tmp_name_arrray[$i],"test_uploads/".str_replace(' ','',$name_arrray[$i])))
{
// save the data to the database
$j=str_replace(' ','',$name_arrray[$i]);
echo $j;
$udate = mysql_real_escape_string(htmlspecialchars($_POST['udate']));
$provider = mysql_real_escape_string(htmlspecialchars($_POST['provider']));
$existfile=mysql_query("select ubatch_file from batches");
while($existing = mysql_fetch_array( $existfile)) {
if($j==$existing['ubatch_file'])
echo' <script>
function myFunction() {
alert("file already exists");
}
</script>';
}
mysql_query("INSERT IGNORE batches SET udate='$udate', ubatch_file='$j',provider='$provider',privilege='$_SESSION[PRIVILEGE]'")
or die(mysql_error());
echo $name_arrray[$i]."uploaded completed"."<br>";
$src = 'test_uploads';
$dst = 'copy_test_uploads';
$files = glob("test_uploads/*.*");
foreach($files as $file){
$file_to_go = str_replace($src,$dst,$file);
copy($file, $file_to_go);
/* echo "<script type=\"text/javascript\">
alert(\"CSV File has been successfully Uploaded.\");
window.location = \"uploadbatches1.php\"
</script>";*/
}
} else
{
echo "move_uploaded_file function failed for".$name_array[$i]."<br>";
}
}
}
// once saved, redirect back to the view page
header("Location:uploadbatches1.php");
}
}
?>
It takes much time because, each and everytime all the files are copied to the newfolder. This exceeds the execution time.Only copying the uploaded files makes uploading and copying files fast.
i have made a small image uploading system using php it was working fine but now when i tried to upload pics in a specific folder then it is giving errors and upload images in root folder only.
the php code is:
<?php
//checking if the user already has a directory or not.
if($r['directory']==0){
$query= "UPDATE user SET directory='1' where id='".$_SESSION['sess_id']."'";
mysqli_query($dbconn,$query);
$path='../akshay/work/'.$r['username'];
mkdir($path) or die("unable to create folder");
} if(isset($_POST['submit'])&& $r['directory']==1){
//uploading users work.
$path='../akshay/work/'.$r['username'];
$name=$_FILES['work']['name'];
$size=$_FILES['work']['size'];
$type=$_FILES['work']['type'];
$tmp_name=$_FILES['work']['tmp_name'];
$extension=strtolower(substr($name,strpos($name,'.') + 1));
//checking if the user has selected a file or not.
if(isset($name)){
if(!empty($name)){
//checking if the uploaded file is an image or not.
if($extension=='jpg'||$extension=='jpeg'&& $type=='image/jpeg'){
$location=$path;
if(move_uploaded_file($tmp_name,$location.$name)){
echo'uploaded succesfully';
}else{
echo'<p style=color:red;>please choose a file</p>';
}
} else {
echo'<p style=color:red;>format of the file must be jpg/jpeg</p>';
}
}
}
}
?>
i think the problem is in move_uploaded_file() function. plz help me fix this problem and please do tell me any other ways (if any) to do this. i am able to make directories using the first check.
the error is "undefined variable:dir_name "and prints the massage "uploaded succesfully".
i have did some editing in the code and now i am able to make a directory in the specified location but cant upload images in that folder instead it uploads the images in 'work' folder and with the username appended to the name of the image.
please help!!!
In else if part of your code, $dir_name is not defined.
So please update your code and add below:
else if(isset($_POST['submit'])&& $r['directory']==1){
$dir_name = $r['username'];
// your code continue..
Furthermore.. the code you are using is not good. as if if condition is true then the else if part will not be executed. so update your code as below:
<?php
//checking if the user already has a directory or not.
if($r['directory']==0){
$query= "UPDATE user SET directory='1' where id='".$_SESSION['sess_id']."'";
mysqli_query($dbconn,$query);
$dir_name=$r['username'];
$r['directory']=1;
mkdir($dir_name);
}
if(isset($_POST['submit'])&& $r['directory']==1){
$dir_name = $r['username'];
//uploading users work.
$name=$_FILES['work']['name'];
$size=$_FILES['work']['size'];
$type=$_FILES['work']['type'];
$tmp_name=$_FILES['work']['tmp_name'];
$extension=strtolower(substr($name,strpos($name,'.') + 1));
//checking if the user has selected a file or not.
if(isset($name)){
if(!empty($name)){
//checking if the uploaded file is an image or not.
if($extension=='jpg'||$extension=='jpeg'&& $type=='image/jpeg'){
if(move_uploaded_file($tmp_name,$dir_name.$name)){
echo'uploaded succesfully';
}else{
echo'<p style=color:red;>please choose a file</p>';
}
}
else
{
echo'<p style=color:red;>format of the file must be jpg/jpeg</p>';
}
}
}
}
?>
use this code ..
$directory ="../images/".$file_name;
move_uploaded_file($temp_name, $directory);
i think this will work for you
I have a php page that is supposed to store the uploaded image to my server. When I run this, I get the "Upload successful" message, but the picture has not been uploaded.
What could it be?
update: can people please leave a comment as to why they down vote my question. I'm new here and I dont know why this question got down voted. thanks
<?
if(!empty($_FILES['uploaded_file'])) {
if ($_FILES['uploaded_file']['error'] > 0 )
echo "Error: " . $_FILES['uploaded_file']['error'] . "<br />";
else{
// Add the original filename to target path.
$target_path = 'MemberPics\\user'.$userid.'.jpg' ;
$success = move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path);
if(!$success) {
echo "There was an error uploading the file, please try again!";
}else {
echo "Upload successful, please go back to your home page";
}
}
}
?>
I believe the problem you are running into is that you are saving the image in an incorrect location (An invalid one from the looks of your link syntax).
Either of these should work:
$target_path = 'MemberPics/user'.$userid.'.jpg' ;
or
move_uploaded_file($_FILES["uploaded_file"]["tmp_name"], "MemberPics/user" . $_FILES["uploaded_file"]["name"]);
