Where is "meta name="description" ..." generated ?

dmb0058 · November 27, 2008, 09:40:34 AM

I can't figure this out at all - I've trawled the forums, googled and fgrepped for several hours and I'm sure it's under my nose somewhere !!

So, sorry for posting what is probably a question with a very ovbious answer but this has me beaten.

I'm using cpg1.4.19 bridged to Joomla on Ubuntu 7.10. An example of one of my image pages (I assume displayed by displayimage.php) contains the following:

Code Select

...
<head>

  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <meta name="robots" content="index, follow" />
  <meta name="keywords" content="space, coins, exonumia, medal, memorabilia, tokens" />
  <meta name="description" content="www.spacecoins.net - coins, medals and other memorabilia of Man's greatest achievement." />
...
<title>spacecoins.net Photo Gallery - Man In Space/Mercury III, Alan B. Shepard</title>
...
</head>
...

The content of the "<meta name="description" ...> tag comes from within Joomla, I would like to replace that content with the image description, as contained in the "<title>" tag, but I can't find where the information is being generated. I assumed it was the pageheader function, but no sign of any code for "meta", "description", "robots" etc. It's not in the theme files, or in the Joomla bridge ones either as far as I can see, so I'm completely stumped.

Any help appreciated.

This thread was moved in error to the bridging sub board. I moved it back. The question is not related to bridging. The meta tags are being composed individually on the coppermine page that calls the pageheader function (as a parameter). To add more meta tags or edit the existing meta tags, edit themes/yourtheme/template.html

Thanks, I've had a look again at that html file. I'm using the water_drop theme, can't see any reference to the description tag.

The code in template.html for the <head> section of the displayed page doesn't contain the meta tags for "robots", "keywords" or "description":

Code Select


...
<head>
<meta http-equiv="Content-Type" content="text/html; charset={CHARSET}" />
<meta http-equiv="Pragma" content="no-cache" />
<title>{TITLE}</title>
{META}
<link rel="stylesheet" href="themes/water_drop/style.css" type="text/css" />
<script type="text/javascript" src="scripts.js"</script>

</head>
...

Comparing this to the <head> section actually displayed (see below, sorry for the large post, thought it better not to snip out sections), it's becoming clearer to me that the CPG template.html is being merged into what I imagine is a Joomla "template" or equivalent. I had expected that the Bridge version of functions.inc.php (specifically the pageheader function) would be responsible but it doesn't appear to be so.

Code Select

<head>

  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <meta name="robots" content="index, follow" />
  <meta name="keywords" content="space, coins, exonumia, medal, memorabilia, tokens" />

OK, I sorted this out. It's sort of a bridging issue - Joomla creates the start of the page, then the bridge modifies the html that's already been created, and then it adds on the html generated by CPG.

In case it's of use to anyone else, what I did was to essentially change the bridge code to remove the Joomla-generated <meta name="description" ...> tag, and then as suggested above, modify the Coppermine theme template so that it provides the tag instead.

My fixes:

1. Change bridge/joomla15.integ.php so that the Joomla meta tag is removed:

Code Select

....
 //remove joomla's title will be overridden by script's one
  $finalOutput=preg_replace('#<title([^>]*)>.*?</title>#si','',$finalOutput);

  // Add this line to scrub the <meta name="decscription" ... tag, use the theme/template.html one
  $finalOutput=preg_replace('#<meta([^>]*)name="([^>\"]*)description"([^>]*)>#i','',$finalOutput);

...

2. Add a line into cpg1419/themes/water_drop/template.html:

Code Select

...
<meta http-equiv="Pragma" content="no-cache" />
<!-- Add the next line so that the image title is displayed as metadata -->
<meta name="description" content="{TITLE}" />
<title>{TITLE}</title>
...

With these changes, all non-CPG pages produced by Joomla wil use the Site|Global Configuration|Metadata Settings values for the description meta tag.
