How to Fetch Selected Post Titles by ID?

  • I want to fetch 5 post titles as a list, and they should be selected by ID.

    I know how to fetch one single post title, I do that like this: 

    // The Query
query_posts('p=52');

    while (have_posts()) : the_post();
		the_title ();
		echo "<br />";
	endwhile;
// Reset Query
wp_reset_query();

    I would like to select 5 titles by 5 different ID’s like so:

    // The Query
query_posts('p=52, 22, 32, 10, 16');

    while (have_posts()) : the_post();
		the_title ();
		echo "<br />";
	endwhile;
// Reset Query
wp_reset_query();

    How can I accomplish that?

    It would be best if the ID’s were separated by a comma. Because they’re saved as a option in ONE row and I intend to fetch them, and then explode and implode them again separated by a comma.

  • Hi Chaseman,
    You can use the following code:

    // The Query
query_posts('post__in' => array(52,22,32,10,16));

    while (have_posts()) : the_post();
		the_title ();
		echo "";
	endwhile;
// Reset Query
wp_reset_query();

    Nice one, thank you, I didn’t even know it works with an array.

    it is not even neccessary to run a query:

    $post_ids = array(52,22,32,10,16);
foreach($post_ids as $post_id) {
echo get_the_title($post_id) . '<br/>';
}

    I couldn’t get either one to work.

    vinay, with your version it will simply fetch all the titles from the database, but not the ones I selected with the id’s.

    alchymyth, with your version it will give me an error saying that I supplied a wrong argument for the foreach statement.

    In both cases I didn’t exactly have an array like in your examples I rather had variables like these ones: 

    $blurb1_title = explode (" ", get_option ('blurb1_titles'));
$blurb_title_ids = implode (", ", $blurb1_title);

    This may be the reason why it didn’t work for me. But I have to somehow fetch the id’s from the database and separate them with commas.

    the first explode will give you the array that you need; assuming that get_option ('blurb1_titles') contain post IDs separated by spaces.

    if they are separated by comma, the explode needs to be changed to:
    $blurb1_title = explode (",", get_option ('blurb1_titles'));

    this might work:

    $blurb1_title = explode (" ", get_option ('blurb1_titles'));
foreach($blurb1_title as $post_id) {
echo get_the_title($post_id) . '<br/>';
}

    To avoid confusion, yes they are separated by spaces.

    So are you saying, I should simply skip the part of imploding them and separating them by commas again? Just exploding is enough?

    Well I will try and see, but what you’re saying makes sense, because it is the explode that gives me the array with the variable. Not sure if I still have an array with the implode or if it’s just a string, never have tried it.

    Ok I just tried it, and it worked GREAT! Thank you a lot alchymyth, I realize there was no need to implode it, simply exploding by the space is enough.

    There’s only one problem with the foreach version, when the database row is EMPTY, meaning there is no entry to begin with, then it will list the first post (post_id=1) for some reason. 

    $blurb_title = explode (" ", get_option ('blurb3_titles'));				

if ($blurb_title != ' ') {
include ($post_title_path);
} else {

}

    The foreach loop is inside the included file.

    I tried to solve this with an if statement and I’ve tried all numerous possible options, !empty, isset, etc. they all don’t work as I expect it.

    I don’t really understand why the variable is simply not considered as empty (I guess because of the explode).
    When I echo out the variable I simply get “Array”.

    EDIT:

    What I know is that it’s NOT equal empty ( == ‘ ‘), but at the same time I don’t know with what it’s filled either. : /

    do the test on the option field and try:

    if ( get_option ('blurb3_titles') != '' ) {

$blurb_title = explode (" ", 				

include ($post_title_path);
} else {

}
