Hi,
to whom it may concern.
I wanted to style the upload-Buttons like all other buttons in the solution via CSS, but this is not possible unless you change
DatebaseFileField.php
in folder
source/classes/controls
to
echo '<label class="btn btn-primary"><input type="File" style="position:fixed; top: -1000px;" id="'.$this->cfield.'" '
.( ($mode == MODE_INLINE_EDIT || $mode == MODE_INLINE_ADD) && $this->is508 == true ? 'alt="'.$this->strLabel.'" ' : '')
.' name="'.$this->cfield.'" ><span>'.##message START_UPLOAD##;
echo '</span></label>
'.$strfilename;
in line 130.
Now it´s a standard class btn-primary in Bootstrap layouts.
