Store variable inside array - PHP

Question

I have some PHP on my site which contains the following portion of code:

'choices' => array ('london' => 'London','paris' => 'Paris',),

Currently this list is static - I manually add to it however I want to generate the list dynamically .

I'm using the following code to create an array dynamically from WordPress & store in a variable:

function locations() {
   query_posts(array('orderby' => 'date', 'order' => 'DESC' , 'post_type' => 'location'));
   if (have_posts()) :
      while (have_posts()) : the_post();
        $locations = "'\'get_the_slug()'\' => '\'get_the_title()'\',";
      endwhile;
   endif;
   wp_reset_query();
   $locations_list = "array (".$locations."),";
   return $locations_list; // final variable
}

Now, this is where I'm stuck :-)

How do I now assign $locations_list to 'choices' ?

I tried 'choices' => $locations_list but it crashed my site.

Many thanks for any pointers.

Answer 1

Erm... whut?

$locations_list = array();
query_posts(...);
while(have_posts()) {
  the_post();
  $locations_list[get_the_slug()] = get_the_title();
}
wp_reset_query();
return $locations_list;

I don't know where you read that you could build variables from a string, but... you can't (except eval ) so just read the array docs and go from there.

Try following:-

function locations() {
query_posts(array('orderby' => 'date', 'order' => 'DESC' , 'post_type' => 'location'));
$locations = array();
if (have_posts()) :
  while (have_posts()) : the_post();
    $locations[get_the_slug()] = get_the_title();
  endwhile;
endif;
wp_reset_query();
return $locations; // final variable
}

You can use this;

<?php
function locations() {
    $locations = array();
    query_posts("orderby=date&order=DESC&post_type=location");
    if (have_posts()) {
        while (have_posts()) {
            the_post();
            $locations[] = get_the_slug() ."#". get_the_title();
        }
    }
    wp_reset_query();
    return $locations;
}

// using
$locations = locations();
foreach ($locations as $location) {
    list($slug, $title) =@ explode("#", $location, 2);
    echo $slug, $title;
}
?>
