My page title is This is my title, if I try and retrieve the ID from the title like this then it does not work:

$mytitle = 'This is my title';
$mytitle2 = get_page_by_title( $mytitle, OBJECT, 'mycustompost' );
print_r($mytitle2);

But if I do this it does work:

$mytitle2 = get_page_by_title( 'This is my title', OBJECT, 'mycustompost' );
print_r($mytitle2);

What gives? Does get_page_by_title not accept variables?

  • Tried it with a page, it works. I suggest you replace print_r by var_dump so that you'll get NULL result if no post is found.

  • I've just tried with var_dump and I am getting NULL. So does that look like its not finding the post? May 23, 2013 at 11:07

    This worked for me: $y = 'Sample Page'; $x = get_page_by_title( $y , OBJECT, 'page' ); var_dump( $x ); You should double check your code (and post type)

  • On testing I can see that it works fine unless the title has a dash, then it fails. Could it be something to do with special characters? May 23, 2013 at 11:13

Man this was an annoying problem for me as well because I a function passing the variable and when tested it showed a value (with special characters, like "&". If I reset the value statically it worked but otherwise same issue. I ran html_entity_decode() on the variable and it now works perfectly so thought I would pass on in case it helps someone. Here was my function:

public function get_id_by_code($coupon){
    $test = get_page_by_title( html_entity_decode( $coupon ), OBJECT, 'coupon' );
    return $test->ID;
}

  • I stumbled on something similar. My CPT entry had a dash in it (entered as a hyphen-minus character), but WP displays it as an em-dash, so when I copied the rendered title into get_page_by_title(), it naturally didn't match what was in the database. It didn't help that my font in Sublime Text makes it very tricky to distinguish between the two as well.

  • This is nuts. The titles for my CPT don't even have special characters in them (alphanumeric with no spaces) yet get_page_by_title() still fails without html_entity_decode(). Thanks for the fix!

Retrieve post/page/custom-post-type id it works fine

$mytitle = 'This is my title';
$mytitle2 = get_page_by_title( $mytitle, OBJECT, 'mycustompost' );
print_r($mytitle2->ID);

Note:enable WP_DEBUG in wp-config.php to see all errors and warnings and use var_dump to check values in variables.

For more info: read get_page_by_title() not returning anything
