Input type File exceeds bytes in PHP

Navigation
1

If I upload a small audio file (15sec) it works fine, but when I do it with a song (4min) it bursts: 

Warning: POST Content-Length of 9042845 bytes exceeds the limit of 8388608 bytes in Unknown on line 0

In the view:

      
<h2>Agregar Categoría</h2> 
<hr/>
<div class="container">
    <form action="AgregarCategoria" method="POST" enctype="multipart/form-data">
        {!! csrf_field() !!}
        <div class="form-group" style="margin-top: 20px;"> 
            <label for="Nombre Categoría">Nombre Categoría:</label>
            <input type="text" placeholder="Nombre de la categoría" name="txtcategoria" id='idtxtcategoria' class="form-control" required>
        </div>    
        <div class="form-group">

            <input type="file" placeholder="Subir la Imagen" name="fileImg"  id='idfileimg' class="form-control"  accept="image/png, .jpeg, .jpg, image/gif"  required>
        </div>
        <div class="form-group">

            <input type="hidden" name="MAX_FILE_SIZE" value="100000" />
            <input type="file" placeholder="Audio" name="fileAudio"   id='idfileaudio'  class="form-control"  required accept=".mp3,audio/*">
        </div>    
        <div class="form-group" >
            <label for="colorin">Elige el color de la categoría:</label><br>
            <input name="color" type="color" id="colorin" value=""/>
        </div>
        <div class="form-group" >    
            <input type="submit" class="btn btn-primary" name="btnEnviarCategoria" value="Agregar">
            <input type="button" name="volver" value="Limpiar" onclick="LimpiarDatos();" class="btn btn-primary"><br><br>
        </div>
    </form>
</div>
<!-- Fin Agregar Categoría -->

On the controller: 

 public function AgregarCategoria(Request $req) {

    $conexion = new Conexion();

    $NombreCategoria = $req->get('txtcategoria');
    $img = $req->file('fileImg');
    $audio = $req->file('fileAudio');

    $ruta_img = $img->getClientOriginalName();
    $ruta_audio = $audio->getClientOriginalName();

    \Storage::disk('local')->put('categorias/pictogramas/' . $ruta_img, \File::get($img));
    \Storage::disk('local')->put('categorias/audios/' . $ruta_audio, \File::get($audio));

    $color = $req->get('color');

    $conexion->insertar_categoria($NombreCategoria, $this->CarpetaCategoria . $this->CarpetaCategoriaPictograma . $ruta_img, $this->CarpetaCategoria . $this->CarpetaCategoriaAudios . $ruta_audio, $color);

    $this->Cerrar_Conexion($conexion);

    return view('admin/administrador');
}

Upload it, upload it well, but if they are heavy files, bust the application and I have put <input type="hidden" name="MAX_FILE_SIZE" value="100000" /> before the file field and nothing.

The problem

The message:

  

POST Content-Length of XXXXXXX bytes exceeds the limit of 8388608   bytes

occurs when you try to send by POST a file whose size exceeds the maximum size allowed for a file that must be sent by POST , set to 8MB or 8388608 bytes, according to the PHP Manual.

Solution

Change the value of post_max_size to a larger value, but taking into account what the PHP Manual says with respect to the value that other variables should have related to post_max_size :

  

post_max_size defines the maximum size of POST data allowed. This option also affects the upload of files. For   upload large files, this value must be greater than    upload_max_filesize . As a general rule, memory_limit must be   greater than post_max_size . When an integer is used, the value of the   same is measured in bytes. You can also use the reduced notation,   as described in this FAQ .

     

If the POST data size is greater than post_max_size , the   superglobal $ _POST and $_FILES will be empty. This can be   track in several ways, for example, passing the variable $_GET   to the script that processes the data, that is, <form action="edit.php?procesado=1"> , and then check if the variable    $_GET['procesado'] exists.

How to configure it?

It can be done through php.ini and in some cases through .htaccess . At least when done by php.ini it is necessary to restart the server for the changes to take effect.

Example using php.ini :

1.

It would be nice if you open php.ini , look for the value post_max_size , if you find it just change the value it has for a larger one. If the line starts with ; , you delete the ; . 

; Maximum size of POST data that PHP will accept.
; Its value may be 0 to disable the limit. It is ignored if POST data reading
; is disabled through enable_post_data_reading.
; http://php.net/post-max-size
post_max_size = 64M

2.

As stated in the manual note above, verify that the value of upload_max_filesize is not greater than the value you set for post_max_size . You should have something like this more or less in php.ini 

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 64M

3.

Verify that the value of memory_limit is not less than the value set for post_max_size . You should have something like this more or less: 

; Maximum amount of memory a script may consume (128MB)
; http://php.net/memory-limit
memory_limit = 256M

4.

Do an operation GRI :):

  • Save your php.ini ,
  • Restart the server
  • Try again to upload the file ...

It should work.

To limit the file upload size, you can use the same fields that the form gives you to determine the size, I'm talking in the PHP part: 

$audio = $_FILES['file']['name'];
$size = $_FILES['file']['size'];
$type = $_FILES['file']['type'];

Then you just have to do something like: 

if(($size <= 0) || ($size > 100000 )) {
    // echo "Fichero muy grande"
    exit();
} else {
    // Subir fichero, guardar y demás acciones
}
