Re: [extend]enable xajax upload files(for xajax 0.2.4)

I guess I had apache down for a while longer ...

This link should be good again (minus the changes above) ... working on making this 0.5 compliant

Re: [extend]enable xajax upload files(for xajax 0.2.4)

Edit: sorry, I noticed later IE pops up a window to download the content of the iframe this way - the XML response. :-(

I modified the code a bit and it seems it is working now, changed only the JS file.

Code: PHP

        iframe.src = 'about:blank';
        
        document.body.appendChild(iframe);
        return iframe;
    }
}
xajax_extend();

Note, I used $xajax->getJavascript("libs/"); to print the javascript, not the usual $xajax->printJavascript("libs/"); since the latter did not include the extended js file.
If anyone it the mood to fix it, I'm curious ;-)
Xajax version was: 0.5rc1

Re: [extend]enable xajax upload files(for xajax 0.2.4)

I'm unable to upload file using xajax_extended
I have placed test file in below mentioned location as you told

1.xajaxExtend.php (server side script, save to the path as xajax.inc.php)
2.xajax_js/xajax_extend.js (browser side script, save to the path as xajax.js)
3.examples/uploadTest.php (demo(show you how it work), save to the tests path.

http://localhost//xajax_0.2.4/examples/uploadTest.php and it open sample interface with file browser.

I'm getting error like : Element with the id "testForm212520000135350848582812983345" not found

When i checked form ID : testForm212520000135350848582812983345 (Sid) , xajaxWork1251997965121 (this.workID)

Not getting any more response,

Thu Sep 03 2009 23:16:53 GMT+0530 (India Standard Time): Element with the id "testForm212520000135350848582812983345" not found.

Does anyone know how to go about submitting this upload form without using a submit button?

Thanks in advanced

Re: [extend]enable xajax upload files(for xajax 0.2.4)

Hi all.
Very great hack, but I found some problems.
I use often functions to handle php functions, like this:

Code: PHP

$reg = array($xajax, 'save_documents');
$xajax->register(XAJAX_FUNCTION, $reg);
 

and the functions described in this topics doesn't work properly. That's because the js function use "xajax" and "xajaxr" in the GET vars, but the xajax->register use a complex style, using for example "xjxevt" for events, "xjxargs" for arguments and so on and so the objPlugins aren't able to catch the arguments.
For example xajaxFunctionPlugin.inc.php has in it:

Code: PHP

if (isset($_GET['xjxfun'])) $this->sRequestedFunction = $_GET['xjxfun'];
if (isset($_POST['xjxfun'])) $this->sRequestedFunction = $_POST['xjxfun'];
 

The solution is quite symple.
Modify xajax_extend.js as follows

Code: PHP

xajax.upload = function(rpcFunc,formID,type,url)
    {
[CUT]


        if(url.indexOf('?') != -1) separator = '&';
//-- Start Mod by Ptah --//
        if (type == 'fun'){
            xajaxArgument = 'xjxfun';
        } else if(type == 'event'){
            xajaxArgument = 'xjxevt';
        } else if(type == 'script'){
            xajaxArgument = 'xjxGenerateJavascript';
        } else if(type == 'style'){
            xajaxArgument = 'xjxGenerateStyle';
        } else if(type == 'arg'){
            xajaxArgument = 'xjxargs';
        } else {
            xajaxArgument = 'xajax';
        }
//-- End Mod by Ptah --//
        url += separator + xajaxArgument + '=' + encodeURIComponent(rpcFunc);
        url += "&xjxr=" + new Date().getTime();
//-- Start Mod by Ptah --//
        url += "&xajax=" + xajaxArgument;
//-- End Mod by Ptah --//
 

Modify xajaxExtend.php as follows

Code: PHP

        $xajaxRequest = array();
//-- Start Mod by Ptah --//
        $method = @$_GET["xajax"];
        $xajaxRequest[$method] = @$_GET[$method];
        $xajaxRequest["xjxr"] = @$_GET[$method];
//-- End Mod by Ptah --//
       // reset RequestMode
[CUT]
//-- Start Mod by Ptah --//
        $xajaxargs = array(get_original_data($_POST));
        $xajaxRequest['xajaxargs'] = $xajaxargs;
        $_POST = $xajaxRequest;
//-- End Mod by Ptah --//
 

and then modify the onsubmit event in the form like this:

Code: PHP

onsubmit="return xajax.upload('name_of_xajax_function','name_of_form', 'type_of_plugin')"
 

where type_of_plugin is one of this:

fun for xajaxFunctions
event for xajaxEvents
script for xajaxScripts
style for xajaxStyles
arg for xajaxArguments
"empty" for using in "easy mode"

That's all folks
(Sorry for my english )
