Catch upload file size exceeded error

For the record, when viewing the entry for a submission where file upload size has been exceeded, the GF admin displays:

FAILED (Temporary file could not be copied.)

This is not a permissions or safe-mode related error, because if I upload a file within the file upload size limit, it works fine.

I really hope there's a way to catch this error, or my project just hit a major problem :-(

Thanks Carl I'll try my own validation. If I do this, does it replace ALL the possible validation message, such as if field is empty, wrong file extension etc? So, I need to rewrite it completely?

Hi,
I'm trying that sample code from the docs:

add_filter('gform_validation', 'custom_validation');
function custom_validation($validation_result){

    // set the form validation to false
    $validation_result["is_valid"] = false;
    $form = $validation_result["form"];

    // specify the first field to be invalid and provide custom validation message
    $form["fields"][0]["failed_validation"] = true;
    $form["fields"][0]["validation_message"] = "TEST This field is invalid!";

    // update the form in the validation result with the form object you modified
    $validation_result["form"] = $form;

    return $validation_result;

}

it just doesn't seem to get called at all?

Can you help?

I am successfully using this in my functions.php, so I pretty sure I'm doing it right:

function change_message_2($message, $form){
  return "<div class=\"woo-sc-box note\">Please check the form & try again. Errors are noted below.</div>";
}
add_filter("gform_validation_message_2", "change_message_2", 10, 2);

Hi, just to update, I think I've got the php sorted to write the validation, but for some reason this filter just isn't working at all now... I need to trouble shoot, disable plugins etc. thanks

Hi there,
I am running into the same issue. When a user submits a file that exceeds the allowed size set on the server, there is no error message displayed. There is an error message for the wrong file extension though. Could the size of the file be checked too? Has anyone got this working?

Other note: Could the wrong extension error be shown as soon as the user has chosen a file - rather than once the submit button has been pressed? Is there a hook to achieve this?

Could this be leveraged by GF?

UPLOAD_ERR_FORM_SIZE Error Code (Use with the MAX_FILE_SIZE Form Field)

The UPLOAD_ERR_FORM_SIZE error code never appears if there is no MAX_FILE_SIZE hidden field in the HTML/XHTML form that contains the <input type="file"> element.

The MAX_FILE_SIZE hidden field is used like this:

<form action="file_upload.php" method="post" enctype="multipart/form-data">
  <p>
    <input name="MAX_FILE_SIZE" value="1048576" type="hidden"/>
    <input name="myFile" type="file"/>
    <input type="submit"/>
  </p>
</form>

Together with this explanation: http://www.php.net/manual/en/features.file-upload.errors.php
But I guess all those error messages happen after the form is actually submitted right?
There is a thought:
I put a function in that Gform validation filter, that uploads the file(s) temporarily to the server, then check if any uploads failed (I could check each file I assume - using that MAX_FILE_SIZE Form Field from above) and then set validation to true or false and give an according error message?
Does that make sense? Is there a Google translate for PHP - like say what you want and it writes the function for you :-)

Can the admins please provide an answer as to how to catch this error... 1.7 is nice and all when it gets here for the time being we need a solution ASAP... please and thank you

gbotica - would you be wiling to share your solution to this, if you have one?
Thanks!
