[RESOLVED] Display Image Errors

[obrienkev]

Hi all,

I have a form that allows a user to upload images.

I want an error message to display if the user has not selected an image to upload.

Here's my code...

FORM:

<?php
// if uploading image error
if(isset($error_message['img_upload']))
{
    echo $error_message['img_upload'];
}

// if image successfully uploaded
if(isset($upload_message['img_upload']))
{
    echo $upload_message['img_upload'];
}
?>

<form action="index.php" name="frm_editor" id="frm_editor" enctype="multipart/form-data" method="post">

<p>
<input type="file" name="img_upload" id="img_upload" value="" />
</p>

<input type="submit" name="submit" id="submit" value="Submit" />

</form>

INDEX.PHP

<?php

// if submitted
if(isset($_POST['submit']))
{

// set vars
$value = stripslashes($_POST['FCKeditor1']);

// $fileName is original file name
$fileName = $_FILES['img_upload']['name'];

// $tmpName is where file went on server
$tmpName = $_FILES['img_upload']['tmp_name'];

// $fileSize is size in bytes
$fileSize = $_FILES['img_upload']['size'];

// $fileType is mime type e.g. image/gif
$fileType = $_FILE['img_upload']['type'];

// $fileError is any error encountered
$fileError = $_FILE['img_upload']['error'];

// Error Checking
if ($fileError > 0)
{
// declare an empty error array
$error_message = array();

switch ($fileError)
{
case 1: $error_message['img_upload'] = 'File exceeded upload_max_filesize';
break;
case 2: $error_message['img_upload'] = 'File exceeded max_file_size';
break;
case 3: $error_message['img_upload'] = 'File only partially uploaded';
break;
case 4: $error_message['img_upload'] = 'No file uploaded';
break;
}
}

// put the file into folder
$uploaddir = 'uploads/';
$uploadfile = $uploaddir . basename($fileName);

if (move_uploaded_file($tmpName, $uploadfile))
{
// declare an empty message array
$upload_message = array();
$upload_message['img_upload'] = 'File Successfully Uploaded';
}

} // end if submit

?>

what is your question kevin?

Hi and sorry for not making myself clear. Been doing that a lot of late!!

Anyway the error checking code is not working correctly.
If the user does not select an image but hits submit the error message does not appear.
If the user submits an image the file uploaded message does not appear.

Any ideas why this is?

Thanks.

yes.
The echoe-ing of the error/upload message is in submit.php, but the processing of the upload happens in index.php; they are not aware of their existence. Move the eco-statements into the index.php/

$upload_message displays correctly now. Didn't need to move anything.

But $error_message still not working.
something to do with error checking??

// Error Checking
if ($fileError > 0)
{
	 switch ($fileError)
	 {
	 	 case 1: $error_message['img_upload'] = 'File exceeded upload_max_filesize';
		 break;
		 case 2: $error_message['img_upload'] = 'File exceeded max_file_size';
		 break;
		 case 3: $error_message['img_upload'] = 'File only partially uploaded';
		 break;
		 case 4: $error_message['img_upload'] = 'No file uploaded';
		 break;
	 }
}

			 // if uploading image error
			 if(isset($error_message['img_upload'])) 
			 { 
			      echo $error_message['img_upload']; 
			 }

		 // if image successfully uploaded
		 if(isset($upload_message['img_upload'])) 
		 { 
		      echo $upload_message['img_upload']; 
		 }

Just realised $_FILES was missing the 'S'!!

Was $_FILE['img_upload']['error'];

Thanks for the help!

Kevin.
