How to set message when result is empty in PocketQuery?

[John Miller]

I am querying several columns from a large database but some of the results are empty because they are so in the database, which is fine. The problem is that when PocketQuery hits an empty result it just echoes that portion of my template, so the row looks like this:

$query.description

Is there a way to change this behavior? I'd like it to say something like "None Available" or just be blank. How can I do this?

I'd also like to know how to set column widths in my template, this isn't working:

<th class="col-$velocityCount" width="70%">Description</th>

Thanks!

Hi John!

Thank you for your interest in PocketQuery! What you want to achieve should be fairly straight-forward.

For the description field, you can simply write this in your template to leave the cell blank:

$!query.description

If you want to write something else if the value is blank, you can do this:

#if($query.description)$query.description#{else}None Available#end

Regarding your column width, you should write some CSS instead of using the width attribute (which is deprecated and not supported in HTML5). You can easily write a <style>...</style> tag on top of your template and write arbitrary CSS. Just make sure you write your selectors with .pocketquery-view in front such that you scope your selectors for the PocketQuery table only. It's described with many references in this StackOverflow article how to style the width of your table columns.

Let me know if you need further help!

I see, thanks! How about if I want to display something particular for a result that is not empty but contains a keyword or something? Like <pre>#if($query.price('0.0'))$query.description#{else}Unlisted#end</pre>

Oops, it didn't like that formatting, but you get the idea: if query.price = 0.0 then show Unlisted.

Try like this: #if($query.price.equals('0.0'))$query.price#{else}Unlisted#end Or if it's a number in your database: #if($query.price == 0.0)$query.price#{else}Unlisted#end
