how to download a file that have been submitted in a php post method? Here is my shot with an image, i have tried a lot of stuff on the server side but it ain’t working.
The client is this:
<form action="Server.php" method="post" enctype="multipart/form-data"> <h1>5</h1> <p>Upload an image</p> <input type = "file" name = "d5" /> <input type="submit" name="submit" value="Submit">
I want the server to download the file uploaded by a button.

You can list it with html Tag <a>
with the location of the file in href
atribute. Need to create the folder uploads
.
If you have any other error, leave a comment.
Look the sample:
index.php
<!DOCTYPE html> <html> <head> <title></title> </head> <body> <form action="server.php" method="post" enctype="multipart/form-data"> Select image to upload: <input type="file" name="fileToUpload" id="fileToUpload"> <input type="submit" value="Upload Image" name="submit"> </form> </body> </html>
server.php
<?php $target_dir = "uploads/"; $target_file = $target_dir . basename($_FILES["fileToUpload"]["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["fileToUpload"]["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["fileToUpload"]["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["fileToUpload"]["tmp_name"], $target_file)) { echo "The file ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"])). " has been uploaded."; } else { echo "Sorry, there was an error uploading your file."; } } ?> <!DOCTYPE html> <html> <head> <title></title> </head> <body> <a href="index.php">retornar ao index</a><br> <a href=" <?php echo $target_file; ?>" download >link for download </a> <br> </body> </html>
