This question has been answered by danilocuculic. See the first response.
When I use this rule in MM_rules: (to get on page Evogallery upload tab)
mm_widget_evogallery('2','','','7');
In Firefox IE there is no problem but in Chrome I get:
ManagerManager: An error has occurred: TypeError - Cannot read property 'hasChildNodes' of undefined and all mm_rules stop working.
<?php
//---------------------------------------------------------------------------------
// mm_widget_evogallery
//---------------------------------------------------------------------------------
function mm_widget_evogallery($moduleid, $title='', $roles='', $templates='') {
global $modx, $content, $mm_fields;
$e = &$modx->Event;
if (useThisRule($roles, $templates)) {
//Include language file
$langpath = $modx->config['base_path'] . "assets/modules/evogallery/lang/";
//First include english
if (file_exists($langpath.'english.inc.php'))
include $langpath.'english.inc.php' ;
//Include current manager language
if (file_exists($langpath.$modx->config['manager_language'].'.inc.php'))
include $langpath.$modx->config['manager_language'].'.inc.php';
$title = empty($title) ? $_lang['mm_tab_name'] : $title;
//TODO: Add iframe autoheight
if (isset($content['id']))
$iframecontent = '<iframe id="mm_evogallery" src="'.$modx->config['site_url'].'manager/index.php?a=112&id='.$moduleid.'&onlygallery=1&action=view&content_id='.$content['id'].'" style="width:100%;height:600px;" scrolling="auto" frameborder="0"></iframe>';
else
$iframecontent = '<p class="warning">'.$_lang['mm_save_required'].'</p>';
mm_createTab($title, 'evogallery', '', '', '<strong>'.$_lang['mm_manage_images'].'</strong>', '100%');
$output = "\$j('#table-evogallery').append('<tr><td>$iframecontent</td></tr>');";
} // end if
$e->output($output . "\n"); // Send the output to the browser
}
?>
Also when I look at my folders in the ManagerManager plugin I don't see the frametab folder.
(...)
<!--?php $output = "\$j('#table-evogallery').append('$iframecontent');";
You can try wrapping one line of code quoted above with setTimeout.
What do you mean, I don't know how to set timeout. PHP is not my language :0
Do I need to use FramedTab widget instead?
