$recent->query of cat problem

    13 years, 5 months ago

    The following is a portion of code from my function.php:

    $recent = new WP_Query();
$catID = "3";
$recent->query("cat=$catID");

    $catID = “3” works.
    $catID = “4” works.
    $catID = “23” does NOT work.

    In order to get a double digit variable to work, I have to change the double quotes in $recent->query to single quotes. But, with single quotes, the single digit variable will not work.

    The problem comes when I loop this function and some variables are single digits, some double.

    Thank you for any help you may be able to offer.

  • $catID is supposed to be an integer – why are you using the quotes?

    Doesn’t $catID = 3; work, without any quotes?

    .. See previous post ?? That.

    The double/single quote problem still happens even without the quotes on the $catID =

    And, the code actually sets the variable elsewhere. Was hoping the cut down code might help, but it just added more confusion. Here’s the real code

    function listGames($catID) {
echo "catID is " . $catID . "<br/>"; // works
$recent = new WP_Query();
$recent->query("cat=$catID");
while($recent->have_posts()) : $recent->the_post(); ?>
.....

    Try

    $recent = new WP_Query( array( 'cat' => $catID ) );
while($recent->have_posts()) : $recent->the_post();

    If that doesn’t work verify that you actually have posts with that category, etc.

    I’m not getting that one to work either. I know I’m doing something REALLY dumb!! And now I see there are problems other than the quote problem.

    single.php

    <?php $i = 1;
$catIDs = array("23","3","4");
foreach ($catIDs as $catID) {
echo "loop #" . $i . "<br />";
listGames($catID);
echo "<br />---------<br />";
$i++;
} ?>

    function.php

    function listGames($catID) {
$recent = new WP_Query();
$recent->query( "cat=$catID" );
while($recent->have_posts()) : $recent->the_post();
the_title();
echo "<br />";
endwhile; }

    OR function.php (from Ron)

    function listGames($catID) {
$recent = new WP_Query( array( 'cat' => $catID ) );
while($recent->have_posts()) : $recent->the_post();
the_title();
echo "<br />";
endwhile; }

    output

    loop #1
POST FROM CAT 4
POST FROM CAT 3
POST FROM CAT 23

---------
loop #2
POST FROM CAT 3

---------
loop #3
POST FROM CAT 4
POST FROM CAT 3

---------

    I think that might actually be working correctly and it’s picking up parent/child stuff.

    categories 3&4 are children of 23
    category 3 is a child of 4

    How do I tell it to ignore parents & children?

    The answer is
    $recent = new WP_Query( array( 'category__in' => $catID ) );

    Thank you EVERYONE for helping me out!!!
