Search for an PHP array element

Question

I have:

Wordpress custom post types;
Two hotels registered in the custom Wordpress admin area;
A variable named $hotels which get the field where the hotels registered are listed;

For the $hotels, I'm using the get_field property that is works like an array. Inside this array, I have to get the name of the post (which is the name of the hotel). I'd like to search into the array the name of the hotel and print it in the page.

If I code:

<?php
  $hotels = get_field('produtos_hotel');
  print_r($hotels);
  $key = array_search('Ocean Maya Royale', $hotels);
  echo $key; // should display 'Ocean Maya Royale';
?>

It will output this mess:

Array (
    [0] => WP_Post Object (
        [ID] => 1113
        [post_author] => 1
        [post_date] => 2014-06-11 16:18:59
        [post_date_gmt] => 2014-06-11 19:18:59
        [post_content] => 
        [post_title] => Ocean Maya Royale
        [post_excerpt] => 
        [post_status] => publish
        [comment_status] => open
        [ping_status] => open
        [post_password] => 
        [post_name] => ocean-maya-royale
        [to_ping] => 
        [pinged] => 
        [post_modified] => 2014-06-18 14:41:25
        [post_modified_gmt] => 2014-06-18 17:41:25
        [post_content_filtered] => 
        [post_parent] => 0
        [guid] => http://localhost/mydocs/advtour/newsite/wordpress/?post_type=add_content&p=1113
        [menu_order] => 0
        [post_type] => add_content
        [post_mime_type] => 
        [comment_count] => 0
        [filter] => raw
    )

    [1] => WP_Post Object (
        [ID] => 1302
        [post_author] => 1
        [post_date] => 2014-06-12 01:19:36
        [post_date_gmt] => 2014-06-12 04:19:36
        [post_content] => 
        [post_title] => Flamingo Cancun Resort
        [post_excerpt] => 
        [post_status] => publish
        [comment_status] => open
        [ping_status] => open
        [post_password] => 
        [post_name] => flamingo-cancun-resort
        [to_ping] => 
        [pinged] => 
        [post_modified] => 2014-06-18 14:40:19
        [post_modified_gmt] => 2014-06-18 17:40:19
        [post_content_filtered] => 
        [post_parent] => 0
        [guid] => http://localhost/mydocs/advtour/newsite/wordpress/?post_type=add_content&p=1302
        [menu_order] => 0
        [post_type] => add_content
        [post_mime_type] => 
        [comment_count] => 0
        [filter] => raw
    )
)

Can you guys see the [post_title] element? So, I have to take the Ocean Maya Royale or the Flamingo Cancun Resort, but the array_search can not find it!

Thank you!

Should be $hotels['post_name']

$srch = 'Ocean Maya Royale';
foreach ($hotels as $key => $val) {
    $key1 = array_search($srch, $hotels[$key]);
    echo $key . ' ' . $key1 . chr(10) . '<br />';
}

It is a second level array and hence needs to be iterated thru. If the search string is to be found in the specific second subscript of 'post_title' it can be hardcoded and the first subscript alone can be returned like.

$srch = 'Ocean Maya Royale';
foreach ($hotels as $key => $val) {
    if ($srch == $hotels[$key]['post_title'])
        echo $key . chr(10) . '<br />';
}

array_search gives you the key for the array, not the variable. So to get the title use this variable:

$theTitle = $hotels[$key]->post_title;
echo $theTitle;

So array_search, when looking for that title, will return the key of 0, because that's which element has that title within it.

//EDIT//

Because you have an array of objects, you need to change your array_search to account for the objects:

array_search(array('post_title' => 'Ocean Maya Royale')

Yeah, that works fine! It got the objects inside the array! Now I'm able to customize it in my away! Thank buddy! =D

What inspired you to changing from wrong answer $theTitle = $hotels[$key]['post_title']; to correct?

Scarraban Over a year ago

Reading the question a second time. Didn't account for the object in the array. You make it sound like you'd prefer the wrong answer :)

Caio Ferrari Over a year ago

But when I used echo $theTitle; it was able to show the hotel name! So, what is wrong with this?

davidkonrad Over a year ago

@CaioFerrari Nothing wrong, just that the accepted answer changed completely from wrong to correct, as soon I posted my $hotels[1]->post_title; now self-deleted answer.

The basic form of filtering using array_reduce:

array_reduce( $hotels, function($result, $item) {
    if ($item->post_title == 'Ocean Maya Royale') {
        $result[] = $item;
    }
}, array());

You can also make it into a function for reusability:

function searchPostTitle($posts, $search_title)
{
    array_reduce( $posts, function($result, $item) use ($search_title) {
        if ($item->post_title == $search_title) {
            $result[] = $item;
        }
    }, array());
}
