I'm new to WP but not PHP.

I've a custom page that I have a PHP call to do some processing on the page content.

the_content() even when enclosed in a function call 

<?php do_something(the_content()  ); ?>

echos the page content.

How do I get the page data without so I can send it to a php function?

the_content does echo the content. That is stated in the Codex-- "Displays the contents of the current post", emphasis mine. Use get_the_content instead, to return a string that you can manipulate.

Be aware that get_the_content does not run all of the same filter as the_content. Again from the Codex:

If you use plugins that filter content (add_filter('the_content')), then this will not apply the filters, unless you call it this way (using apply_filters):

<?php apply_filters('the_content',get_the_content( $more_link_text,> $stripteaser, $more_file )) ?>

  • Perfect many thanks. I'm finding getting to grips with the lexian used is the hard bit with WP.

  • Frequently, the_ echoes, get_ returns a string, but I think there are exceptions.

  • @s_ha_dum I find the tricky part is remembering when it's get_the_ vs. just get_ (like get_the_content() or get_permalink()).

  • @PatJ : Yes, I know. get_permalink gets me all the time.
