Symfony2-maxSize参数不适用于文件上传

Question

I have a file uploading function on my Symfony2 project.

I am seting the maxSize parameter like that:

$manuscript_file = new File(array(
        'maxSize' => '20M',
        'mimeTypes' => array(
            'application/msword',
            'application/zip',
        ),
        'mimeTypesMessage' => 'Please upload a valid manuscript file. Valid types are: doc, docx, zip',
    ));

The problem is that when I am trying to upload a 2M or 3M word file, I am getting the validation message:

 The file is too large. Allowed maximum size is 20M bytes.

Did you faced that? Or is my code wrong.

I took the example from the Symfony documentation:

Symfony File - Validation Constraints Reference

Answer 1

I already faces this issue, so I post this solution (I think this is the same issue for you).

This is a known bug of Symfony, in fact the framework will display the validator error message also when the file size is too high for your PHP configuration, instead of getting the classical PHP error.

In your current PHP config, you probably limited the max upload size to 2M, so Symfony display the wrong error.

So check your php.ini file (/etc/php5/apache2/php.ini on Linux) and increase max_upload_size to fit your field :

upload_max_filesize = 20M

Don't forget to restart apache : apache2ctl restart

Now it should work !

Note that's probably fixed on the last Symfony version, another solution is perhaps to upgrade your project to sf2.3 (but i'm not sure of that) ^^

Answer 2

I created a jQuery validation method to prevent sending big files to server because php don't valide it (It is in Spanish):

$(function() {
    //Validate 20MB
    validarFileSize('#carga_telefonos_form_file', {{ 10*1024*1024 }}, '#div-mensaje-file-size', '#botonSubmit');
});

function validarFileSize(campo, maximo, divMensaje, btnGuardar) {
    console.debug("validarFileSize. Campo: " + campo + ", maximo: " + maximo);
    $(campo).bind('change', function() {
        var size = this.files[0].size;
        if (size > maximo) {
            $(divMensaje).show();
            $(btnGuardar).attr('disabled', 'disabled');
        } else {
            $(divMensaje).hide();
            $(btnGuardar).removeAttr('disabled');
        }
    });
}

如果您使用POST上传文件，请当心php.ini中的post_max_size限制
