Which PHP file would a custom theme_link function go into?

Question

For some Taxonomy term pages I would like to change the "Read More"

link to "More info". Using theme developer, I see it’s using the theme_link function and gives a candidate function name.

If I re-write this function, in which PHP file would I put this custom function?

Answer 1

theme_link() doesn't use a template file. You can override its output by placing your own theme function in your theme's template.php file:

function MYTHEME_link($variables) {
  //Alter this as you see fit
  return '<a href="' . check_plain(url($variables ['path'], $variables ['options'])) . '"' . drupal_attributes($variables ['options']['attributes']) . '>' . ($variables ['options']['html'] ? $variables ['text'] : check_plain($variables ['text'])) . '</a>';
}
