Output value of field array

[Peter Knight]

I've created several fields and want to output their values on my page.

Normally, the following works fine

<?=$page->field-name-here?>

For my latest fields this doesn't work and is instead outputting an integer (which I imagine is the page number).

<h4>Course Details</h4>
<strong>Level:</strong> <?=$page->course_detail_level->title?><br />
<strong>Category:</strong> <?=$page->course_detail_category?><br />
<strong>Grouping:</strong> <?=$page->course_detail_grouping?><br />

The above fields are mostly all based on a Page type and then an input field type of AsmSelect.

I imagine my issue is that I am therefore dealing with an array and need to create a foreach statement?

Making progress. Because each field must be an array, it appears I do need to loop through each.

This is working but perhaps not the way I *should* be solving it

<?php
$course_level = $page->course_detail_level;
$course_category = $page->course_detail_category;
$course_grouping = $page->course_detail_grouping;
$course_prerequisite = $page->course_detail_prerequisite;
$course_writer = $page->course_detail_writer;
$course_lessons = $page->course_detail_lessons;
			
foreach($course_level as $level){
echo "<strong>Level:</strong> {$level->title}";}
			
foreach($course_category as $category){
echo "<strong>Category:</strong> {$category->title}";}

foreach($course_grouping as $grouping){
echo "<strong>Grouping:</strong> {$grouping->title}";}
			
foreach($course_prerequisite as $prereq){
echo "<strong>Prerequisite Course:</strong> {$prereq->title}";}
			
foreach($course_writer as $writer){
echo "<strong>Writer:</strong> {$writer->title}";}
			
foreach($course_lessons as $lesson){
echo "<strong>Lessons:</strong> {$lessons->title}";}
			
?>

Hey Peter,

If there is more than one value in the page field array, then looping is likely what you want, but if the page field is set to only allow one option, then you are better off with your good friend "first":

$page->course_detail_level->first()->title

Thanks Adrian. 
In this instance there are multiple values so all is cool in looping land.

Why do you feel that it's not the way you should be doing it? The only case where I think there could be a cleaner way is if you only wanted to print a comma separated list of the titles of the items inside the Page-fields. Then you could do

<h4>Course Details</h4>
<strong>Level:</strong> <?= $page->course_detail_level->implode(", ", "title"); ?><br />
<strong>Category:</strong> <?= $page->course_detail_category->implode(", ", "title"); ?><br />
<strong>Grouping:</strong> <?=  $page->course_detail_grouping->implode(", ", "title"); ?><br />

Otherwise, just stick with the loops

More a reflection on my PHP noob-ness. Somtimes you discover *a* way to do something, stick with it and don't realise it may not best practice.
