I am trying to convert a post title to a slug. I used sanitize_title_with_dashes, thinking that's what WordPress uses. However, if my post title has an apostrophe in it, sanitize_title_with_dashes does not strip out the apostrophe. Instead, it escapes the apostrophe with a backslash.

For example, if I use the default post editor to create a post named "Bob's Boutique", WordPress core will correctly create the slug as "bobs-boutique".

If I try to convert "Bob's Boutqiue" to a post slug using sanitize_title_with_dashes in functions.php, the result is "bob\'s-boutique".

Is there an additional function that WordPress uses when making slugs that strips out apostrophes?

    echo sanitize_title_with_dashes("Bob's Boutqiue") outputs bobs-boutique, I don't get an escaped quote.

  • sanitize_title_with_dashes should work, so we need to see more code to know why the value is being escaped - perhaps you are also wrapping it in a WordPress esc_html or another function.

Use this function to remove the apostrophe:

preg_replace( "/[:’]/", "", $title );

  • Really? Add it where exactly? Can we just drop that in functions.php and BAM! It works?

  • What @s_ha_dum means is that this is not gonna work.. the very least it requires is to inside a function, allowing the $title to be passed to it..
