Problem with uploading files to the server

Question

I’m learning to use a server cloud and I’m having trouble uploading files.

I made a code with simple PHP and HTML:

<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="img" />
<input type="text" name="titu" placeholder="Titulo" />
<input class="lal" type="submit" name="cadastrar" value="Cadastrar" >    
</form>

<?php
  require_once 'conexao.php';
  if(isset($_POST['cadastrar'])){

    /* IMAGEM */
    $img    = $_FILES['img'];
    $name   = $img ['name'];
    $tmp    = $img ['tmp_name'];
    $size   = $img ['size'];
    $ext    = end(explode('.',$name));      
    $pasta    = "../imagem/";
    $maxSize    = 1024 * 1024;
    $permiti    = array('jpg', 'jpeg', 'png');         
    $titu         = filter_input(INPUT_POST, 'titu');

    if(empty($titu)){echo "Informe um titulo";  
    }else{      

      $name = uniqid().'.'.$ext;
      try{    
          $stmte = $pdo->prepare("INSERT INTO post(TITULO, IMAGEM) VALUES (:1, :2)");
          $stmte->bindParam(":1", $titu  , PDO::PARAM_STR);
          $stmte->bindParam(":2", $name  , PDO::PARAM_STR);   
          $executa = $stmte->execute();

          if($executa){        
            echo 'Dados inseridos com Sucesso';
            $upload   = move_uploaded_file($tmp, $pasta.$name);   
          }
          else{
            echo 'Erro ao inserir os dados';
          }
        }
    catch(PDOException $e){
    echo $e->getMessage();
    }}}
?> 

And the comic book record is going perfectly, so much so that I can get into phpMyAdmin and see there the newly added record as well as updating the home page where the posts are displayed.

But as you can see, I’m uploading an image file but, although the record is being successfully inserted into the BD, the move_uploaded_file does not move the temporary file as it should.

And that’s my problem because I have to display the post with the image, but as this is not being sent, it does not exist.

I don’t understand why, since if I run the code on my PC, with WAMP, both the registration and the upload work normally. And the server appears to work, since it does not return any error message, but the upload is not performed.

I don’t think it’s any wrong code because I’ve used that same code several times on shared servers and it’s always worked. The problem is only on this server cloud.

I believe that the problem may lie in the very configuration of cloud, because I’ve even changed the folder’s permission images for 777 and nothing.

I also changed some PHP.INI directives as shown in the image below:

Would anyone know the cause?

Answer 1

Note: This answer was posted before the author of the question changed the code.
_{To later question, on the basis of screenshot, may be the cause of the problem.}

Anyway, I’ll leave it here because it may (eventually) be useful to someone.

Missed in the question the form send to see if everything is ok.

Adjusting PHP to show errors

Put these 3 lines at the beginning of your PHP

   ini_set('display_startup_errors',1);
   ini_set('display_errors',1);
   error_reporting(E_ALL);

But be careful: once everything is up and running, remember to remove them.

It’s supposed to be like this all the way from the beginning:

<?php
   ini_set('display_startup_errors',1);
   ini_set('display_errors',1);
   error_reporting(E_ALL);

   require_once 'conexao.php'; // Cadê o caminho correto? Solução: DOCUMENT_ROOT

   if(isset($_POST['cadastrar'])) {
   ⋮

Note that I removed one ?> and <?php unnecessary in require_once.

On the sliders to separate the directories:

One of the things is to trade the bars for DIRECTORY_SEPARATOR on these two lines:

  $pasta   = '..'.DIRECTORY_SEPARATOR.'imagens'.DIRECTORY_SEPARATOR;
  ⋮
  $mppasta   = '..'.DIRECTORY_SEPARATOR.'videos'.DIRECTORY_SEPARATOR;

Another is to take the bar of these, as they have already been defined in the variables:

  $upload   = move_uploaded_file($tmp, $pasta.$name);
  $upload   = move_uploaded_file($mptmp, $mppasta.$mpname);

(or even leave the PATH_SEPARATOR here, and take from the variables)

Improving the paths with $_SERVER['DOCUMENT_ROOT']:

Better than using '.. ', it would be the case to put the right way using $_SERVER['DOCUMENT_ROOT'], so you would have no danger of making confusion with relative paths.

  require_once $_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'conexao.php';
  ⋮
  $pasta   = $_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'imagens'.DIRECTORY_SEPARATOR;
  ⋮
  $mppasta   = $_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'videos'.DIRECTORY_SEPARATOR;

This server variable usually returns something like this (it depends on how the server was configured, of course):

/var/www/NOMEDOSITE/httpdocs

Just be careful in the local copy to keep the same test directory structure.

Remember to adjust the intermediate folders with the full path.

About the permissions:

Normally on the server you will have to give greater permission in the folders, so that it can record the files. This is because the user who runs the server web (Apache, etc.), be different from the user who sends FTP.

• One way would be by the FTP program itself. In Filezilla, for example, you can mark the folder with the mouse, and select "permissions". Just connect the square allowing writing to "Group" and "Other" (W/G/O).

• The other by shell Linux, with the commands chmod 777 imagens and chmod 777 videos (the 777 allows everyone to write in the folder, it is important to know this and take proper care).

And one more fuzz to "debug" the code:

Assuming you used DIRECTORY_SEPARATOR as recommended above, swap the move_upload_file for this, to better see where the fault happens:

if($executa){
   if( is_uploaded_file( $tmp ) ) {
      if( !move_uploaded_file( $tmp, $pasta.$name ) ) {
         echo 'Arquivo 1 nao foi movido';
      }
   } else {
      echo 'Arquivo 1 nao veio pelo upload';
   }

   if( is_uploaded_file( $mptmp) ) {
      if( !move_uploaded_file( $mptmp, $mppasta.$mpname ) ) {
         echo 'Arquivo 2 nao foi movido';
      }
   } else {
      echo 'Arquivo 2 nao veio pelo upload';
   }
}
