Guess my problem is closely related to this one : Snippet duplicates content when used multiple times on page
The elements of my problem are the following ...
$modx->loadedResources : an (empty) array registered in the main $modx object via a snippet on page load. The array holds resource id's of the resources fetched from the DB randomly, so the same resource isn't shown twice on the same page.
loadRandomResource : a snippet using XPDO-style querying to load a random resource from the DB. It uses $modx->parseChunk() to fill the placeholders in the chunk with the resource data. With each call, it appends the id of the fetched resource being fetched to the $modx->loadResources array.
I used some debugging to check if the resource id's were properly being stored in my array, each time I fetch a new random resource, which happens to be the case. I then checked if the db returns different results, each time I call the loadRandomResource snippet, and it does. I can also confirm that it doesn't return duplicate results (I exclude the already loaded resource ID's in my XPDO query).
However, when calling the snippet at 3 various locations throughout my page template, all 3 snippet calls render the same resource, which is weird, since my debug shows that unique data is being loaded from the DB, and being sent to the chunk for rendering.
Please find below both the snippet code, as well as the chunk mark-up.
Does anyone have any ideas? Any help is much appreciated!
loadRandomResource snippet
$criteria = $modx->newQuery('modResource');
$criteria->select(array('id','pagetitle'));
$criteria->sortby('RAND()');
$criteria->limit(1);
$whereOptions = array(
'parent' => 2,
'deleted' => false,
'hidemenu' => false,
'published' => true
);
if (!empty($modx->loadedResources)) {
$whereOptions['id:NOT IN'] = $modx->loadedResources;
}
$criteria->where($whereOptions);
$resources = $modx->getCollection('modResource', $criteria);
$output = '';
foreach ($resources as $resource) {
$fields = $resource->toArray();
$fields['tv.tvPersonalPicture'] = $resource->getTVValue('tvPersonalPicture');
$fields['tv.tvJobTitle'] = $resource->getTVValue('tvJobTitle');
$output .= $modx->parseChunk('cnkTeamListItem', $fields);
$modx->loadedResources[] = $fields['id'];
}
return $output;
cnkTeamListItem chunk
<div>
<img src="[[+tv.tvPersonalPicture]]" alt="[[+pagetitle]]" />
<h2>[[+pagetitle]]<br /><span>[[+tv.tvJobTitle]]</span></h2>
</div>
I found the answer myself, solution is a bit odd though ...
I was calling my custom snippet 3 times in my template, uncached. Each call though exactly looked the same ...
[[!loadRandomResource? &type='teammember']]
Even though I had the exclamation mark in place, still ModX was caching the call, within the same page request.
So when I added a random unique value to each of the 3 calls, the issue was solved.
Call 1 : [[!loadRandomResource? &type='teammember' &unique='123465']]
Call 2 : [[!loadRandomResource? &type='teammember' &unique='987654']]
Call 1 : [[!loadRandomResource? &type='teammember' &unique='666666']]
Don't know if this is a bug or a feature, but I thought that the exclamation mark prevented caching, both across different pageviews, as well as within the same page view. Anyhow, thx for helping.
I use this code for rendering chunks in snippents:
<?php
// get chunk or template
$tplRow = $modx->getOption('tplRow', $scriptProperties, '');
// get template
if (substr($tplRow, 0, 6) == "#CODE:") {
$tplRow = substr($tplRow, 6);
} elseif ($chunk = $modx->getObject('modChunk', array('name' => $tplRow), true)) {
$tplRow = $chunk->getContent();
} else {
$tplRow = false;
}
// render template
$field = array(); // your fields
if ($tplRow) {
$chunk = $modx->newObject('modChunk');
$chunk->setCacheable(false);
$chunk->setContent($tplRow);
$output[]= $chunk->process($fields);
} else {
$output[]= '<pre>' . print_r($fields, 1) . '</pre>';
}
You do realize you could have done this with getResources, don't you?

&sortby=`RAND()`&limit=`1`

I want to override the item listing template file core/themes/classy/templates/dataset/item-list.html.twig for listing the fields field_slider_images as well as field_blog_tags respectively of their's multiple values of the field.
I have selected "Unordered List" in the view.
Please do check the attached image.
I have created following files :
item-list--field-blog-tags.html.twig
item-list--field-slider-images.html.twig
But, this is not rendered for the listing of the fields.
When I have created item-list.html.twig then only it will access.
However, both fields have different data to style and I am not able to get the current field name which is loading it's data in item-list.html.twig.
Had a brief look at this and it doesn't seem that 'item-list' to have suggestions, which is quite unfortunate.
In this situation there are two options:
Create your own suggestion which would accomplish exactly what you need.
You'll have to do something like this:
/
/*add new variable to theme with suggestion name*/
function hook_theme_registry_alter(&$theme_registry) {
$theme_registry['item_list']['variables']['suggestion'] = '';
}
//send a value to newly added variable to use it build the suggestion
function hook_ENTITY_TYPE_view(array &$build, $entity, $display, $view_mode) {
//add condition here if field exists or whatever, do the same for other field
$build['field_slider_images']['#suggestion'] = 'field_slider_images';
}
//use newly added variable to build suggestion
function hook_theme_suggestions_THEME_HOOK(array $variables) {//THEME_HOOK=item_list
$suggestions = array();
if(isset($variables['suggestion'])){
$suggestions[] = 'item_list__' . $variables['suggestion'];
}
return $suggestions;
}
Now you should be able to use item-list--field-slider-images.html.twig
Second option is to do what others in core did: use a new theme
function hook_ENTITY_TYPE_view(array &$build, $entity, $display, $view_mode) {
//add condition here if field exists or whatever, do the same for other field
$build['field_slider_images']['#theme'] = array(
'item_list',
'item_list__field_slider_images',
);
}
I am building a CMS that supports a website which also contains an SMF forum (2.0.11). One of the modules in the CMS involves a "report" that tracks attendance. That data is queried to tables outside of smf, but in the same database. In addition to what it does now, I would also like for a post to be made in a specific board on the SMF forum containing the formatted content. As all of the posts are contained by the database, surely this is possible, but it seems there is more to it than a single row in a table.
To put it in the simplest code possible, below is what I want to happen when I click Submit on my page.
$title = "2015-03-04 - Attendance";
$author = "KGrimes";
$body = "Attendance was good.";
$SQL = "INSERT INTO smf_some_table (title, author, body) VALUES ($title, $author, $body)";
$result = mysqli_query($db_handle, $SQL);
Having dug through the smf DB tables and the post() and post2() functions, it seems there is more than one table involved when a post is made. Has anyone outlined this before?
I've looked into solutions such as the Custom Form Mod, but these forms and templates are not what I am looking for. I already have the data inputted and POST'ed to variables, I just need the right table(s) to INSERT it into so that it appears on the forum.
Thank you in advance for any help!

Code where you want to create post:
//Define variables
//msgOptions
$smf_subject = "Test Title";
//Handle & escape
$smf_subject = htmlspecialchars($smf_subject);
$smf_subject = quote_smart($smf_subject, $db_handle);
$smf_body = "This is a test.";
//Handle & escape
$smf_body = htmlspecialchars($smf_body);
$smf_body = quote_smart($smf_body, $db_handle);
//topicOptions
$smf_board = 54; //Any board id, found in URL
//posterOptions
$smf_id = 6; //any id, this is found as ID in memberlist
//SMF Post function
require_once('../../forums/SSI.php');
require_once('../../forums/Sources/Subs-Post.php');
//createPost($msgOptions, $topicOptions, $posterOptions);
// Create a post, either as new topic (id_topic = 0) or in an existing one.
// The input parameters of this function assume:
// - Strings have been escaped.
// - Integers have been cast to integer.
// - Mandatory parameters are set.
// Collect all parameters for the creation or modification of a post.
$msgOptions = array(
'subject' => $smf_subject,
'body' => $smf_body,
//'smileys_enabled' => !isset($_POST['ns']),
);
$topicOptions = array(
//'id' => empty($topic) ? 0 : $topic,
'board' => $smf_board,
'mark_as_read' => true,
);
$posterOptions = array(
'id' => $smf_id,
);
//Execute SMF post
createPost($msgOptions, $topicOptions, $posterOptions);
This will create the simplest of posts with title and body defined by you, along with location and who the author is. More parameters can be found in the SMF functions database for createPost. The SSI and Subs-Post.php includes must be the original directly, copying them over doesn't do the trick.
I'm using a service called Embedly to style my RSS feeds from Google Feedburner. I have an example code over her: JsFiddle
If you look closely you will see the source (CNN) at the end of every title. This is called .provider I would like to get rid of the whole div (.embed) IF the the word CNN is located elsewere (meaning duplicate) in the div, either .description or a
I tried many things, this is one of them really straight forward code:
$('.embed').each(function() {
if($('.embed a:first **could also be .description**', this).text() == $('.provider', this).text())
$(this).remove();
});
I cant figure out why its not working. I also used it with on and live click with no luck.
I just realized the 'embeds' are not there on document tready. I added a button with click event which you can click after the embedly has loaded in: http://jsfiddle.net/2VBSX/37/
You can use success event to filter provider class from the data like this :
EDITED
$('div.newscontainer').embedly({
key: ':3eccf441bf0f43acbb076da9817af27d',
success: function(oembed, dict) {
output = $(oembed['code']);
description = $(oembed['code']).find(".description").text();
var regex =new RegExp(output.find('.provider').text(),"i");
if(regex.exec(description) == null ) {
$(dict["node"]).parent().html(output);
}
output.find("a:eq(0)").text(); // First
output.find("a:eq(1)").text(); // Provider
}
});
Checkout this jsfiddle demo
Is it that what you want?
var regex = /CNN/;
$('.embed').each(function(index, element) {
if (regex.exec($('.embed a:first').text()) != null
&& regex.exec($('.provider').text()) != null) {
element.remove();
}
});
I managed to pull out data using autocomplete at my local (http://mysite.dev/swan/autocomplete). The json data is displayed.
But when I applied the same module at live (now a subdomain: http://test.mysite.com/swan/autocomplete with different drupal installs), this autocomplete fails to pull out data. No json data is displayed.
Do you have any idea if this is related to cross domain issue, or any possible cause I might not be aware of?
This is the callback:
/**
* Callback to allow autocomplete of organisation profile text fields.
*/
function swan_autocomplete($string) {
$matches = array();
$result = db_query("SELECT nid, title FROM {node} WHERE status = 1 AND type='organisation' AND title LIKE LOWER ('%s%%')", $string, 0, 40);
while ($obj = db_fetch_object($result)) {
$title = check_plain($obj->title);
//$matches[$obj->nid] = $title;
$matches[$title] = $title;
}
//drupal_json($matches); // fails at safari for first timers
print drupal_to_js($matches);
exit();
}
Any hint would be very much appreciated.
Thanks
It's the conflict with password_policy.module. Other similar modules just do the same blocking. These modules stop any autocomplete query.
What I am looking for is a page_id/view_id that I can use to identify and style specific pages. I would use the title or the url, but there is a chance that it could change if the a higher-up decides that the page should no longer be called Golf, but rather Tee-Time because he likes it better.
Presumably this identifier would not change if the current page were to be a paged view (page 1,2,3,4...).
One way of solving this is the following. It's depending on the url, so if it changes, so does the class-name.
In my themes template.php I implemented hook_preprocess_page:
function mytheme_preprocess_page(&$vars, $hook) {
$body_classes = array();
$body_classes[] = 'page-' . _get_page_name($_SERVER['REQUEST_URI']);
$vars['body_classes'] = implode(' ', $body_classes);
}
function _get_page_name($request_uri) {
static $numeric_subsection = array(
'/node/' => 'node',
);
$preAlias = $request_uri;
$alias = substr(strrchr($preAlias, "/"), 1);
if (strpos($alias, '?') > -1) {
$alias = substr($alias, 0, strpos($alias, '?'));
}
$page_name = $alias;
if (empty($alias)) {
$page_name = 'start';
}
else if (is_numeric($alias)) {
foreach ($numeric_subsection as $section => $pn) {
if (strpos($preAlias, $section) > -1) {
$page_name = $pn;
}
}
}
return $page_name;
}
Then in the main page-template:
<body class="<?php print $body_classes; ?>">
This isn't a generic solution. So you'll probably have to customize this for your specific needs. It will for example need som tweaking to play nicely with path auto.
This depends a little on how your site is put together (panel pages, view pages, "normal" pages). Essentially, you need to figure out what vars are in scope, and then determine which information in them can be used. To determine what is in scope, you can use print_r(array_keys(get_defined_vars())); and then poke around in the individual vars.
An option is to do something in theme_preprocess_page. One option is to get the page data via page_manager_get_current_page(), poke around in there, and then add body classes as needed. Without knowing what you are doing, you essentially need to print_r the results somewhere, look at what you have, and go from there.
