Question

Stripping images from post teasers/excerpts in Wordpress

Answer 1

A:

You probably want to use the semantics of in your pages, similar to how post excerpts work. You can get the list of subpages http://codex.wordpress.org/Template_Tags/wp_list_pages from here and then iterate over them (the above document has an example for styling the names of pages). you can then get the page contents with a custom function and do whatever you want with it.

http://www.mattvarone.com/wordpress/functionsphp-wordpress-themes/

That url explains how to add your own custom functions to a given theme.

I already have the content of the posts using a custom function. The problem is I have html content in a php variable, and if the first thing in that post is a giant image, my blog would end up looking broken when that excerpt is displayed as a huge image after I call echo

Sorry, I didn't answer the question you asked. There is an answer that uses regex above, which is an acceptable solution. There is a function in the php language, strip_tags, http://php.net/manual/en/function.strip-tags.php that provides basic sanitization (you can specify a list of allowed tags). You can also use a real parser for XHTML.

Answer 2

+1 A:

And after you got the content in a html variable a small regular expression should do the rest

$content = preg_replace("/<img(.*?)>/si", "", $content);

Should do the trick

Answer 3

A:

You could use the the_excerpt() which automatically grabs just the text or you can use a more sophisticated version of the same thing called The Excerpt Reloaded
