File upload using $ _FILES and PHP

Question

Today I first tried to upload files to my site, but it does not seem to work. Hope someone can help me and I hope my code is readable :)

The problem is that when I select a file and a SUBMIT form, it is not accepted because $_FILES is NULL

 if (move_uploaded_file($_FILES['obrazok']['tmp_name'], $uploadfile)) 

UPDATED Error

 Warning: move_uploaded_file(www_nekonomagic/res/img/anime/uploads/793392545Untitled.jpg): failed to open stream: No such file or directory in /home/gj020900/www_nekonomagic/admin/admin-nove-anime.php on line 107 Warning: move_uploaded_file(): Unable to move '/home/gj020900/tmp/php9izgwb' to 'www_nekonomagic/res/img/anime/uploads/793392545Untitled.jpg' in /home/gj020900/www_nekonomagic/admin/admin-nove-anime.php on line 107 

Short form:

 <form enctype="multipart/form-data" action="../admin/admin-nove-anime.php" method="post" role="form"> <div class="form-group col-md-6"> <!-- MAX_FILE_SIZE must precede the file input field --> <input type="hidden" name="MAX_FILE_SIZE" value="3145728" /> <label for="obrazok" class=""> Obrázok anime (Max. 3MB):</label> <input type="file" name="obrazok" id="obrazok" class="form-control" required> </div> <div class="form-group col-md-12"> <input type="submit" class="btn btn-success" name="pridaj_anime_submit" value="Pridať anime" style="width: 100%;"> </div> </form>

Answer 1

MAX_FILE_SIZE is in bytes to limit the size of the downloaded file to 3M, convert your size to bytes.

 1024 * (1024 * 3) // 3145728 

Then change your hidden input to the next

 <!-- MAX_FILE_SIZE must precede the file input field --> <input type="hidden" name="MAX_FILE_SIZE" value="3145728" /> 

Answer 2

Everything is good. You just need to change this:

 $uploaddir = '/www_nekonomagic/res/img/anime/uploads/'; 

to

 $uploaddir = 'www_nekonomagic/res/img/anime/uploads/'; 

Answer 3

Change the directory directory path string to:

 $uploaddir = '/www_nekonomagic/res/img/anime/uploads/'; 

You forget to add a backslash to the end of downloads. Make the changes as described above and check if the file is saved in the directory. Thanks.

Try checking if the temp file is uploaded or not:

 if(is_uploaded_file($_FILES['obrazok']['tmp_name'])) { echo "Temp file uploaded. \r\n"; } else { echo "Temp file is not uploaded. \r\n"; }
