echo returns "Array"

  • I’ve created a table (rjecnik) in the wordpress database and I’m trying to retrieve data from it with:

    <?php
    $izraz=$wpdb->get_results(“SELECT ‘engleski’ FROM ‘rjecnik’ WHERE ‘id’=2”);
    echo $izraz
    ?>

    It’s returning – Array. Why?

    Because the get_results function returns an array

    Thanks, but I bumped into another problem. The previous piece of code was written in a page template together with an HTML form. I didn’t know which URL to put into the action attribute, so I made a new PHP file called database_list.php (in the child theme folder):

    <?php
	if (isset ($_GET['upis'])&&!empty($_GET['upis'])){
	$upis=$_GET['upis'];
  	$mocnesi=$wpdb->get_var("SELECT engleski, prijevod FROM rjecnik WHERE id = $upis");
	echo $mocnesi;
  	}
?>

    And I moved the form code into the main page:

    <form action="database_list.php" method="get">
  Upisite rijec!
  Trazena rijec: <input type="number" name="upis">
  <input type="submit" value="Trazi">
</form>

    I don’t know how to return the $mocnesi value found by the query to html to display. Any help?

    Have you tried looping through it using a “foreach” PHP loop?

    I had problems with picking the right array type. Works with associative. Thanks!
