   I would like to know if it is possible to dynamically change meta tags
   from php. I have a site that has a wordpress "PAGE" that runs php code to dynamically create content. The php code can potentially create hundreds or thousands of pages dynamically - like a products page on an eCommerce site. The site is
   http://www.kipssite.net/wpblog/?page_id=1991

   I am somewhat new to wordpress and not sure if there is a php function to accomplish this. The <title> tag is already there and I want to
   modify it for each page. The description and keywords meta tags are
   not there and I need to add these. I am assuming there is a php function to add a meta tag.

   I tried this line of code but it did not add any tags.
   Not sure if this is what I need.

   add_action('wp_head','addMyMetaTagInfo');

   So to summarize I want to add or change the Title, Description and
   Keywords meta tags on dynamically created wordpress pages.

   I know there are meta tag plugins but my understanding is that these
   are only for static wordpress pages.

   If you can provide examples with code that would be a big help.

   Thank You.

   Not within WordPress - no.

   I tried this line of code but it did not add any tags

   And did you create aaddMyMetaTagInfo() function to go with it?

   I know there are meta tag plugins but my understanding is that these are only for static wordpress pages.

   No - they work in all types of pages - static & dynamically generated.

   Thanks for the reply.

   I did not know I needed the addMyMetaTagInfo() function.
   Not sure how to use it though. I don't see any info on this function either.

   I'm still unclear how a meta tag plugin would help me insert meta tag info dynamically unless it has some functionality that lets me provide the meta information as the user requests a new page. The information to be presented in the meta tag is not available until the user makes a selection that runs a MySQL query. Thus it can only be provided as the php code gets it.

   Thank You for your assistance.

   Sorry. Did not quite get what you were saying.
   I was thinking there was another function I needed to run.
   Yes, I did create my own addMyMetaTagInfo()
   function. I should have added this to my question.

   Here is the complete code I tried.

   add_action('wp_head','bn_addMetaTagInfo');
   //-----------------------------------------------------
   function bn_addMetaTagInfo()
   {
   echo '<title>My Title</title>';
   echo '<meta name="description" content="My Description" />';
   echo '<meta name="keywords" content="My Keywords" />';
   }

   Thanks.

   That's because there is no addMyMetaTagInfo() function in WordPress core.

   I resolved this by inserting my own php code in the header.php file
   for the theme I was using. To clarify - the header.php file you want to alter is within the theme's root folder. In this case the theme is called Finesse and I altered the header.php code as shown:

   //Original line

   <title><?php $theme->meta_title(); ?></title>

   /*Altered line - NOTE: I removed the <title> ... </title> and inserted this line. You could comment out the <title> line if you want. build-meta-tags.php is my own code which uses information from the query string at the end of my URL. I used this to create the <title> as well as the description and keywords meta tags. Some of the information to use in the tags came from a MySQL query to a table which the user can alter for the various meta tag information they may want to show.*/

   <?php include_once('build-meta-tags.php') ?>
