Body
I have a problem with upload file forms. I'll write here a simple example of code which is not working in all the browser. HTML part is something like this: <pre><code> <form method="POST" enctype="multipart/form-data" action="match.php"> <input class="btn btn-info" name="dataset" type="file" id="dataset" /> <input class="btn btn-info" type="submit" name="submit" value="Submit" /> </form> </code></pre> Then, then in match.php file I get and process the file, for example like this: <pre><code>if ($_FILES["dataset"]["error"] > 0 || !($_FILES["dataset"]["size"] > 0)) { $dataset = "default.txt"; echo 'error:' . $_FILES["dataset"]["error"] . ' - filesize:' . $_FILES["dataset"]["size"]; } else { $dataset = $_FILES["dataset"]["tmp_name"]; echo "Ok"; print_r($_FILES); } </code></pre> Very easy: if there are errors during the upload process I will use a default file (and print some error information), otherwise everything's ok. Well, this works perfectly except in some browsers. For example I encountered the problem with Android default browser (not with Chrome), and it seems with some browsers in Windows systems too (I didn't tried it by myself, to be sincere). Using error information I print, it looks like there's no error in <code>$_FILES["dataset"]["error"]</code> (output is 0), but the filesize is 0 (just on these browsers). There's no problem with folders permissions (I write files in folders using "default.txt" file information), there's no problem with php.ini settings (actually I tested it with the same txt file which is 65kb).

1. COI think some mobile browsers don't support file uploads at all. That could be the issue.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
