How to add elements to individual pages?

[[email protected]]

Hey everyone.

I am just beginning to learn about hooks and is() things. I have a need to add specific elements to only specific pages before the main content wrap so that is is full with. probably do action(gensis_after_nav, golf_slider) function golf_slider is a slider that is just for one page of the site.

Does anyone know how I can do the is (page) and have it be limited to one specific page?

this is what i have so far.

it didnt work though
add_action('genesis_before_loop','golfcourseslider');

function golfcourseslider() {
if (is_page('golf-course-homes')) {
add_action(genesis_after_header,golf_course_slider);
}
}

function golf_course_slider(){
layerslider(4);
}

The is_page() function accepts a $page parameter

Ref: https://codex.wordpress.org/Function_Reference/is_page

This means that you are able to target a single page by its ID, slug, page title etc

e.g.

if ( is_page ( 'your-page-slug' )  )  {
  // do stuff
}

or, by page ID. e.g page id 10

if ( is_page ( 10  ) ) { // 
    // do stuff
}

If you wished to target a group of pages, then you could do so by using an array. For example

if ( is_page( array( 42, 54, 6 ) ) ) { 
    // do stuff
}

Perhaps a typo in your code above

add_action(genesis_after_header,golf_course_slider);

should read

add_action( 'genesis_after_header', 'golf_course_slider' );

tried this too

add_action('genesis_before_loop','golfcourseslider');

function golfcourseslider() {
if (is_page('golf-course-homes')) { 
add_action(genesis_after_header,golf_course_slider);
}
}

function golf_course_slider(){
	echo do_shortcode('[layerslider id="4"]');
}

[Graham]

The single quotation marks are necessary

add_action( 'genesis_after_header', 'golf_course_slider' );

oh doh! I am a PHP infant. Thanks so much for pointing this out.

ok added the single quotation marks and now my code looks like this.

add_action('genesis_before_loop','golfcourseslider');

function golfcourseslider() {
if (is_page('golf-course-homes')) {
add_action('genesis_after_header,golf_course_slider');
}
}

function golf_course_slider(){
echo do_shortcode('[layerslider id="4"]');
}

I honestly dont think that I would like to use the shortcode for the layer slider. the code is also given for php "<?php layerslider(4) ?>"

The revised code still did not work however. The slug is golf-course-homes. not sure if it has to be in quotes or anything.

Is there a specific place within the functions.php file where this section of code needs to be placed?

Oh my goodness!! I am so hasty! I ust put quotes around the whole thing! hahaha. wow sorry for that. Lets close those quotes properly and see if it works.

add_action('genesis_before_loop','golfcourseslider');

function golfcourseslider() {
if (is_page('golf-course-homes')) {
add_action('genesis_after_header','golf_course_slider');
}
}

function golf_course_slider(){
echo do_shortcode('[layerslider id="4"]');
}

that is what I have now. Still not working.

Try this

add_action('genesis_meta','child_maybe_show_slider');

function child_maybe_show_slider() {
	if (is_page('golf-course-homes')) {
		add_action( 'genesis_after_header', 'golf_course_slider' );
	}
}

function golf_course_slider(){
	echo do_shortcode( '[layerslider id="4"]' );
}

well that worked!
any reason why that worked and mine didnt?

[Graham]

I used an earlier hook. By the time genesis_before_loop came along, it was too late. genesis_after_header had already happened

Glad it worked 🙂 Are you able to mark as resolved?

Yeah I can mark as resolved. In the interest of not creating another thread. Can I use two conditional tags in one function?

ex. is_page(!Home,!golf-course-homes)

[Graham]

Generally, for the sake of others, it's better to start another thread 🙂 .. yet ...

Functions are defined, you can only use them in the way that they are built. If the function were built in a way that accepts two parameters, then yes you could ( the syntax isn't right in the above, but no matter in this example ).

In this case, the is_page() function only accepts one parameter.. the $page parameter - as documented in the WordPress codex. The parameter for this function has to be of a certain type and format.

It's all fun and games... happy Googling !

A way of approaching what i think you are looking for might be something like this

function child_maybe_do stuff() {
	if ( !is_page('golf-course-homes')  ||  !is_home() ) {
		// do stuff
	}
}

curses... wont let me edit.

Meant this

function child_maybe_do stuff() {
	if ( !is_page('golf-course-homes')  &&  !is_home() ) {
		// do stuff
	}
}
