Using Web Link attributes in a Snippet

I have written a snippet and it works fine but I now want to add the Web Link Attribute field so I can optionally open the link in a new window.

My current working line of code is $output .= ’<ul><li> <a href="[~’ . $children[$i][’id’] . ’~]" ’ . ’>- ’ . $children[$i][’pagetitle’] . ’</a></li></ul>’;

I have tried adding $children[$i][’linkattributes’] . into the line in the correct location after the href but it does not make any difference.

Have I missed something? Apologies if this is a really dumb question that is documented somewhere.

Also can I use the same syntax to access template variables as I cannot get these to work either?

Apart from this I am finding MODx very useful and have achieved everthing that I need so far.

Many thanks

David

For the first question, try using (note the underscore): $children[$i][’link_attributes’]

For the second question, how are you populating the $children array? There are a couple of MODx methods you may be interested in, these are $modx->getDocumentChildrenTVars() and $modx->getDocumentChildrenTVarOutput().

Both of those methods will retrieve the document children and merge in the TV values for the documents at the same time - the first one giving ’raw’ TV values, while the latter will give you the processed TV values.

Thanks for that - I have got it working now!!!

I didn’t fully understand and had not included the link_attributes in the call to get the data. I have modified that line as well

$children = $modx->getDocumentChildren($doc[’id’], 1, 0, ’id, pagetitle, editedon, link_attributes’, $whereClause, $sortBy, $sortDir);

From what you say I suppose I could just remove the fields parameter to return everything.

This solves my immediate problem but I will work on getting TVs working as well.

Thanks again for such prompt responses.

Best wishes

David
