php's strip_tags() won't work
I'm trying to tweak a tiny bit a wordpress, but i am level 0 in php, so i kinda suck :/
I want to add a custom 'tweet this' button (i know there already is a gazillion of them, i just wanted to do it on my own, for fun)
So, i'm trying this :
<a href="http://twitter.com/home?status=<?php strip_tags(the_excerpt()) ?>" >tweet this</a>
"<p> ... excerpt ... </p>" and the strip_tags function does not strip those
<p> tags !
What do i do wrong ?
Thanks, and sorry if it is obvious.
Your problem is that
the_excerpt() does not return its contents to
strip_tags(), but outputs it directly using
strip_tags() (which would need a preceding
echo by the way to do any work) can't do anything.
Use get_the_excerpt() instead (line break inserted for clarity, remove when using):
<a href="http://twitter.com/home?status= <?php echo strip_tags(get_the_excerpt()); ?>" >tweet this</a>
By the way, I would also
urlencode() the excerpt, you're bound to run into trouble otherwise if it contains
"double quotes or other funny characters.
This doesn't look right by common sense:
<?php strip_tags(the_excerpt()) ?>, then the WP doc explained, the_excerpt's API doc, it said it echoes instead of returning it.
ob_start to workaround.
ob_start("callback"); the_excerpt(); $excerpt = ob_get_contents(); ?> <a href="http://twitter.com/home?status=<?php echo strip_tags($excerpt) ?>" >tweet this</a> <?php
Note: I don't have any WordPress API experience.
