I am trying to output a list of categories per an article. I am using the following code,
<?php wp_list_categories('child_of=270&style=none'); ?>
(string) Style to display the categories list in. A value of list displays the categories as list items while none generates no special display method (the list items are separated by <br> tags).
How do I remove the stupid <br /> after each output?
Frustrating how this code
<?php the_category(', '); ?>
Will output the links without a line break…
Any help would be greatly appreciated.
I came to a solution for this by reviewing the WordPress Codex. The trick is to turn off the automatic echo of wp_list_categories, and then use str_replace(). My example follows:
<?php $variable = wp_list_categories('child_of=270&style=none&echo=0'); ?>
<?php $variable = str_replace('<br />', '', $variable); ?>
<?php echo $variable; ?>
The only real change in your query is the inclusion of “echo=0” which will return the information in a variable rather than just displaying it.
The real work is done by str_replace() which looks for any <br /> tags and removes them from the string. Then just echo out the updated string and no more breaks!
