Get title of a page contained in a field

[sarah_hue]

Hi,

well, here's something I just don't understand and didn't find an explanation in the reference for.

I've got a number of pages:

• Home
  • Author
    • Tomas Tranströmer
    • José Saramago
    • Kenzaburō Ōe
    • ...
  • Nobel prize
    • 2012
    • 2011
    • ...

I created a field "author", type Page, which contains all these 3rd level pages (Tomas Tranströmer, José Saramago, Kenzaburō Ōe, ...). In the template used i.e. for /nobel-prize/2011, the "author" field is populated and contains the page ("Tomas Tranströmer").

Now I would like to create an output:

$content .= $pages->get($page->author)->title;

Confusingly, the output is

Home

although the output for

$content .= $page->author;

is

1026

and the output for

$content .= $pages->get(1026)->title;

is the desired

Tomas Tranströmer

So I seem to create a problem with using $pages and $page in the same line, but what is it exactly and how will I fix it?

Thanks a lot!

You do get the page object right away from the field. So this is enough.

echo $page->author->title;

Thanks, you're absolutely right. I thought I tried this in first place, I've seen too much code yesterday, I suppose.

Thank you for the above. Unfortunately I cannot get it to work in my scenario where I have a foreach loop:

<?php 
$children = $page->children;
?>
<div class="listings">
<?php
foreach ($children as $child) {
?>
<div>
 <p><?=$child->headline?></p>
 <p><?=$child->property_display_price?></p>
 <p><?=$child->fields->property_category->label?>:  <?=$child->property_category->title?></p>
</div>
<?php 
}?>
</div>		

The only way I could get the 'property_category' label to display on the front end was as above specifying the 'fields' object and the property_category title is blank.

The property_category title value gets called from another page from a 'page' dropdown. Like sarah_hue, I've tried lots of variations and the only way I can get the remote page title to display on the front end is to hard code the remote page id:

<?=$pages->get('1088')->title?> 

Where 1088 is the selected value of the dropdown.

All help most welcome.

Is property_category a single reference or multiple?

Hi soma

Not sure what you mean. This is my first PW site. I'm converting an existing site from another CMS.

'property_category' is a dropdown (single select). The $child page also contains other fields that are checkbox groups using the 'page' field type but haven't got to those yet.

Does this make my question clearer?

[Soma]

On a page field you can configure if it's multiple or single value. If it's multiple it will be a page array and your method doesn't work cause you need to specify which in the array you want the tytle from. if you only need single value you also need to make the field single value.

[psy]

Woohoo! Got it. Thank you Soma. So much to learn!

Solution: do as you say above and make the field Single page (Page) or empty page (NullPage) when none selected, then in the template:

<p class="type"><?=$child->fields->property_category->label?>:  <?=$child->property_category->title?></p>

Still had to put $child->fields->property_category->label but all part of the learning process.

Cheers

Hi,

Running into some issues with this myself - I have multiple pages referenced and want to output the title of these pages - works when I have a single page option but either getting the ID's (i.e. 1144|1089) or nothing when I try to call title... can someone help me? Sorry, have looked around a lot but just not getting the concept!

Thank you very much.

  <?php 
   if ($page->children) {
            foreach($page->children as $selectedthumbs) {    
                echo "<tr><th><a href='{$selectedthumbs->url}'>{$selectedthumbs->title}</th><th>{$selectedthumbs->contributors}</th></</tr>";    
        }}
    ?>

Hello @Jon E

However, you use $page->children which is the reference to "children" in the context of the Page Tree. When dealing with page reference fields of templates, you need to reference the page reference field by its name, something like $page->my_tags for example:

<?php namespace ProcessWire;
     foreach($page->selectedthumbs as $selectedthumb) {
       echo "<tr><th><a href='{$selectedthumb->url}'>{$selectedthumb->title}</a></th><th>{$selectedthumb->contributors}</th></</tr>";
}

BTW:

• You  do not need the if clause in this case, because if your PageArray is empty, the loop will not run in the first place.
• You left out the closing tag of <a> element

If you are getting Page IDs then you are probably on the right track as that means you have a PageArray there. In ProcessWire the __toString() magic method renders the IDs when you access them as if they were strings. Meaning when you see them, you need to loop through the variable in question instead of echoing it.

Hope this helps. If not, please provide more code and info about the context you are having trouble with.
