target page with php based on page slug - php

Question

Lets say I have six pages in wordpress
example.com/apples
example.com/art
example.com/bananas
example.com/broccoli
example.com/cars
example.com/cats
I want to target pages which slugs begin with specific letter
if (page slug beginns with "a"){
echo 'content for pages with slug beginning with a';
}
else if (page slug beginns with "b"){
echo 'content for pages with slug beginning with b';
}
else if (page slug beginns with "c"){
echo 'content for pages with slug beginning with c';
}
How do I write this correctly

Answer 1

Referring to this answer here, I'd say it's safe to get the URL like this:
/** Get the queried object and sanitize it */
$current_page = sanitize_post( $GLOBALS['wp_the_query']->get_queried_object() );
/** Get the page slug */
$slug = $current_page->post_name;
And then:
/** Get the first character */
$slugBeginsWith = substr($slug, 0, 1);
/** Apply your logic */
if($slugBeginsWith == 'a')
{
echo 'content for pages with slug beginning with a';
}
elseif($slugBeginsWith == 'b')
{
echo 'content for pages with slug beginning with b';
}
elseif($slugBeginsWith == 'c')
{
echo 'content for pages with slug beginning with c';
}
However you didn't mention what is your goal here. Maybe if you provide more information in your question we could help better!

Answer 2

you need to get the firstcharacter by using php substr function. place following code in functions.php file
add_filter('the_content', 'change_content_by_firstCharacter');
function change_content_by_firstCharacter( $content ) {
global $post;
$post_slug = $post->post_name;
$firstCharacter = substr($post_slug, 0, 1);
if ( $firstCharacter == 'a' ) {
$content = 'content for a goes here';
} else {
return $content;
}
}
