Question

The following code filters posts from the database by certain fields.

array('key' => 'telephone', 'value' => '0','compare' => '>')

Some other factors determine if there might be another array here. The problem is the code required to work that out will return a variable. $filters;

Is this possible

$filters = array('key' => 'mobile', 'value' => '0','compare' => '>')

array('key' => 'telephone', 'value' => '0','compare' => '>') . $filters

And if not how could this work.

CLARIFICATION

This is the structure that the function would require this to be in.

    'meta_query' => array(
array('key' => 'telephone', 'value' => '0','compare' => '>'),
array('key' => 'mobile', 'value' => '0','compare' => '>')
                        ) 

But we can’t write it out like that as other factors determine what these queries will be. We have to get something like a variable containing the arrays to go inside the ‘meta_query’ array.

Answer 1

I assume that you are trying to pass it multiple filters in a single array.

Using . won’t work because that is a string concatenation operation.

Use this for an array of arrays:

$filters[] = array('key' => 'mobile', 'value' => '0','compare' => '>');
$filters[] = array('key' => 'telephone', 'value' => '0','compare' => '>');

To get the right format for the function simply:

$meta['meta_query']=$filters;
