So I&#39;ve ran into an interesting issue, and wanted to solicit feedback from people more involved with ahah/ajax development for drupal than I....<br><br><a href="http://malsup.com/jquery/form/#code-samples">http://malsup.com/jquery/form/#code-samples</a> -- see the file uploads tab and the information regarding json/javascript responses.<br>
<br>The concrete issue I&#39;m dealing with is the Add another item button for CCK...&nbsp; For Filefield if you&#39;ve selected a file to upload and press the &#39;Add Another Item&#39; button you get an error. You get this error because drupal_json sets the text/javascript header, and the iframe doesn&#39;t accept that... <br>
<br>This issue can be solved easily just by having CCK&#39;s ahah handler simply print drupal_to_js instead of using drupal json.&nbsp; This however will not solve more systemic issues with people adding file uploads to other ajax handled forms.<br>
<br>There are a couple solutions I can think of...<br>&nbsp;&nbsp; 1) have ahah set the iframe option to true and use iframes, and add the textarea to drupal_json.<br>&nbsp;&nbsp; 2) check the _SERVER[&#39;HTTP_ACCEPT&#39;] and decide which header to set whether to wrap output in a textarea<br>
&nbsp;&nbsp; 3) hack around it on a case by case basis<br><br>I was hoping some of the more jquery ahah astute might have better suggestions for achieveing some kind of consistency.<br>We should probably add $_GLOBAL[&#39;devel_shutdown&#39;] = FALSE to drupal_json regardless...<br>
