I have read through and experimented with the API, but I am unable to figure out how to display the name of the collection or tag name when you are browsing items.
Currently... "Browse Items (## items)"
Desired ... "Browse Collection Name (## items)
or .... "Browse Tag Name (## items)
I'm seeing the ability to display the collection name when viewing an individual item, but not the full list.
As Omeka stands today, is there a means of doing this? Thanks!
Hi mjcpl:
You could add some custom code to your items/browse.php file, something like this:
<?php
if ($collection = get_collection_by_id($_GET['collection'])) {
$html .= 'Collection: '.$collection->name;
}
if ($tags = html_escape($_GET['tags'])) {
$html .= 'Tags: '.$tags;
}
echo $html;
?>This is getting each of the parameters passed to the URL, and adding their values to a $html variable, then echoing that variable.
Best,
Jeremy
That was exactly what I needed. You are a scholar and a gentleman!
I'm learning php as I go. I understand what you did in general, but I'll need to read up on $_GET to "get it".
Thanks again!
Glad to help! $_GET is a reserved variable in PHP for retrieving variables passed to the URL:
Hi,
I am working with a similar situation. When I use this same code, however, it prints the words "Tags: Array" on browse pages such as items/browse/tags/tag+name. Do I need something else after the .$tags code?
The code reads:
<?php
if ($collection = get_collection_by_id($_GET['collection'])) {
$html .= ' '.$collection->description;
}
elseif ($tags = get_tags($_GET['tags'])) {
$html .= 'Tags: '.$tags;
}
echo $html;
?>Any suggestions would be much appreciated.
Thanks!
Hi cabusara,
If you change get_tags to html_escape in the elseifit should work OK. Was there a reason you wanted to use get_tags instead?
Best,
Jeremy
I am using get_tags because html_escape returns nothing (no error message, just a blank space on the page where the tags text should be).
I tried html_escape again just to double check, and indeed, the system returns nothing. So, neither get_tags or html_escape seem to work.
Just to get a larger picture of what is going on on the rest of the page's code, here is what things look like. Everything else is working, except for this get_tags (which returns Tags: array) and html_escape (which returns nothing).
<h1>
<?php
if ($collection = get_collection_by_id($_GET['collection'])) {
$html .= ' '.$collection->description;
}
elseif ($tags = html_escape($_GET['tags'])) {
$html .= 'Tags: '.$tags;
}
echo $html;
?></h1>
<?php while (loop_items()) {
switch (item('collection name')) {
case 'Question1':
common('browseq');
break;
case 'Question2':
common('browseq');
break;
case 'Question3':
common('browseq');
break;
case 'Question4':
common('browseq');
break;
case 'Question5':
common('browseq');
break;
case 'Forum Scholars':
common('browses');
default:
common('browse');
}
}
?>
The code as you have it should work if you have in fact returned a query string in the url, i.e. have something like browse?tags=lorem at the end of the url.
Are you trying to return the tags for an instance other than browsing items by a tag?
Aha, that gave me an idea. The tags urls are linking to pages with addresses like "/items/browse/tag/lorem"
I checked the command I am using to get the tag links on pages... I am using:
<?php echo item_tags_as_string(); ?>
This automatically links all my tags to pages with urls like "/items/browse/tag/lorem"
So, I went into the application/helpers/ folder and modified "TagFunctions.php" so that the section that reads
/**
* Retrieve a tag cloud of all the tags for the current item.
*
**/
function item_tags_as_cloud($order = 'alpha', $tagsAreLinked = true, $item=null, $limit=null)
{
if (!$item) {
$item = get_current_item();
}
$tags = get_tags(array('sort'=>$order, 'record'=>$item), $limit);
$urlToLinkTo = ($tagsAreLinked) ? uri('items/browse/tag/') : null;
return tag_cloud($tags, $urlToLinkTo);
}Now reads
function item_tags_as_cloud($order = 'alpha', $tagsAreLinked = true, $item=null, $limit=null)
{
if (!$item) {
$item = get_current_item();
}
$tags = get_tags(array('sort'=>$order, 'record'=>$item), $limit);
$urlToLinkTo = ($tagsAreLinked) ? uri('items/browse?=tags') : null;
return tag_cloud($tags, $urlToLinkTo);
}Now everything is working, and the html_escape function is returning the tag names.
Thank you for the help!
