Foreach loop returning only last result - php

Question

I need to format a YYYY-MM-DD date to output like "12 January 2020", I have got the date to output correctly, but the code will only output one of the five values that I want, I've obviously missed something.
I'm having an issue where the following code only outputs a single result:
function populate_dropdown($form){
//Reading posts for "Events" post type;
$posts = get_posts("post_type=el_events&orderby=date&order=asc&el_eventcategory=flo-talanoa&numberposts=-1");
//Creating drop down item array.
$items = array();
//Adding post dates titles to the items array
foreach($posts as $post)
$unformatteddate = $post->startdate;
$dateTime = DateTime::createFromFormat("Y-m-d", $unformatteddate);
$dateformatted = $dateTime->format('j F Y');
$items[] = array(
"value" => $dateformatted . ': ' . $post->location,
"text" => $dateformatted . ': ' . $post->location
);
//Adding items to field id 1.
foreach($form["fields"] as &$field)
if($field["id"] == 1){
$field["type"] = "select";
$field["choices"] = $items;
}
return $form;
}
If I replace:
$unformatteddate = $post->startdate;
$dateTime = DateTime::createFromFormat("Y-m-d", $unformatteddate);
$dateformatted = $dateTime->format('j F Y');
$items[] = array(
"value" => $dateformatted . ': ' . $post->location,
"text" => $dateformatted . ': ' . $post->location
);
With:
$items[] = array("value" => $post->startdate . ': ' . $post->location, "text" => $post->startdate . ': ' . $post->location);
The code outputs all five values (though with YYYY-MM-DD date format), what am I missing? I'm a novice when it comes to PHP.
Thanks in advance

Answer 1

You forgot to add {} in your foreach loop
foreach($posts as $post){
$unformatteddate = $post->startdate;
$dateTime = DateTime::createFromFormat("Y-m-d", $unformatteddate);
$dateformatted = $dateTime->format('j F Y');
$items[] = array(
"value" => $dateformatted . ': ' . $post->location,
"text" => $dateformatted . ': ' . $post->location
);
}
//Adding items to field id 1.
foreach($form["fields"] as &$field){
if($field["id"] == 1){
$field["type"] = "select";
$field["choices"] = $items;
}
}

You were missing the curly braces {} in foreach.
