Problem when taxonomy value is zero

[Doublespark]

Hi,

I am using taxonomy to select values from 0 to 5+

I then output something like:

Bedrooms = 4
Bathrooms = 2

My problem is if I select the value 0 I expect to output:

Garages = 0

But the 0 is missing, leaving me with:

Garages = 0

Is there a solution or workaround that will enable me to display a value of zero?

Example can be seen here: http://cms-1.doublespark.eu/catalogue-properties.html

Thanks in advance.

Gary.

Rather use a numer field with min and max values. This is a much better idea, as I've already done a property catalog before.

Taxonomy values are stored as their IDs not the name or alias, which will make it impossible to create a range filter, eg between 2-4 bedrooms.

Thanks for the tip, appreciated!!

Hi Thyon,

I changed as suggested, now using a number field but still if I input "0" (zero) the number still does not display, in the ouput. If I change it to >=1 then it displays fine.

See the first listing here http://cms-1.doublespark.eu/catalogue-properties.html

Garage Spaces should display as x0

The listing below it shows fine with a numeric value of 1.

This is my template code:

<span class="garage_spaces">x<?php echo $entry['data']['garage_spaces']['value']; ?></span>

and this is the output:

<span class="garage_spaces">x</span>

I must be doing something wrong, but unsure what.

Any further advice much appreciated.

Cheers,

Gary.

You're not doing anything wrong, but most clients don't want a field displayed unless its value is NON-NULL. If you look at the catalog_full.tpl file, you will notice that it checks if the value is zero before display. You can remove that check, change it to bypass if it's garage (or a list of fields) or simply create a completely custom template that will display even 0 as its value.

To bypass the zero value check list of fields (bedrooms, garage) you can use this:

<?php if ((strlen($data['raw']) && !in_array($field, array('catalog_name','parentJumpTo'))) || in_array($field, array('bedrooms','garage'))): ?>

Sorry Thyon, I tried the 1st way and removed the 0 check for garages etc - but it still did not display.

I've stripped the template as fas as possible, and I'm left with this:

<?php if (count($this->entries)): ?>

<div class="layout_full">
<?php foreach ($this->entries as $entry): ?>
<?php endforeach; ?>

</div>
  <div class="layout_full">
    <div class="header"><?php echo $entry['data']['disp_address']['value']; ?>, <?php echo $entry['data']['postcode']['value']; ?></div>
    <div class="image"><?php echo $entry['data']['property_image']['value']; ?></div>
    <div class="summary_text">
      <div class="price">

&pound;<?php echo $entry['data']['price']['value']; ?></p></div>
      <div class="property_description"><?php echo $entry['data']['property_description']['value']; ?></div>
    </div>
    <div class="icons">
      


        <span class="bedrooms">x<?php echo $entry['data']['bedrooms']['value']; ?></span>
        <span class="receptions">x<?php echo $entry['data']['receptions']['value']; ?></span>
        <span class="bathrooms">x<?php echo $entry['data']['bathrooms']['value']; ?></span>
        <span class="showers">x<?php echo $entry['data']['showers']['value']; ?></span>
        <span class="garage_spaces">x<?php echo $entry['data']['garage_spaces']['value']; ?></span>
      </p>
    </div>

Must be something wrong in my code?

[thyon]

yes. just move the "endforeach" to AFTER all your manual placement code. Its looping through all the entries (even if its just 1) and then it reaches your code with a blank variable.

Why not also look at the templates tutorial:

Hi ,
you can make it with an if else construkt i think.
I made this normaly with images like that ->

<?php if($entry['data']['immo_bild']['meta']):?>
  <dd class="bild">
    ">[img]<?php echo $entry['data']['immo_bild']['meta']['0']['src']; ?>[/img]" width="200" height="100" />
  </dd>
<?php else: ?>
<?php endif;?>

So I have an code when I have an image and nothing when no image is there...
When you try the same like :

<span class="garage_spaces">x<?php if($entry['data']['garage_spaces']['value']):?><?php echo $entry['data']['garage_spaces']['value']; ?><?php else: ?>0<?php endif;?></span>

I think that would give you the way you want. Normaly a Number of garages and when no garage is there you get an 0.

@Thyon - Thanks for pointing me in the right direction. This is my 1st time with Cat & CatExt, the fact I have got this far is testimony to your coding and documentation skills. Before starting I printed all three docs/tutorials and still refer to them every few mins. Not being very code orientated it is difficult to understand some of the code, but with help I am managing to "cut & paste" and achieve the desired results. I'm sure the php understanding will get better with time. Thanks again.

@MacKP - Cheers, that works a treat, I now have Garages x0 :-)

If the value disappears because of a zero value, you can also FORCE the field to generate a number, but specifying the number format with a "0" as the parameter, e.g. 0 decimals.

Thanks Thyon, that will come in handy. Cheers.
