Hi, I use this code for a view, which shows all actual WooCommerce orders.

add_filter( 'wpv_filter_query', 'func_filter_custom_date_with_fulldaytime1', 99, 3 );
function func_filter_custom_date_with_fulldaytime1( $query_args, $settings, $view_id ) {   
    if ( $view_id == 11983) {
          if ( (isset($query_args['meta_query'])) && (!empty($query_args['meta_query'])) ) {  
           $target_field = "wpcf-booking-datetime"; // change this field slug to your field slug
              
             foreach ($query_args['meta_query'] as $key => $value):
                                       if ($value['key'] == $target_field){                                                                                    
                                              $day_start_time =   $value['value'];
                                              $day_end_time = strtotime('+1 day', $day_start_time) - 1;
                                                              $filer_index = $key;                                         
                 }
            endforeach;
                
            if ( isset($filer_index) ) {
                   
                $query_args['meta_query'][$filer_index] = array('key' => $target_field, 
                                                                  'value' => array($day_start_time, $day_end_time), 
                                                                  'type' => 'NUMERIC', 
                                                                  'compare' => 'BETWEEN' );
                                                                  }             
        }   
       
     }
    return $query_args;
}

It works perfectly, but when I check my server logs I see a lot of errors "PHP Warning: Illegal string offset 'key' in ...."

Here is a query URL example we are using.

What am I doing wrong?

Thanks.

Hello,

The problem seems to be here
$value['key']

The value variable doesn't have a key attribute based on the message. Can you perform a var_dump on the $value variable and let me know what is inside that variable.

Thanks,
Shane

The foreach goes through all queries parameters and $value contains following values:

array(4) { ["key"]=> string(21) "wpcf-booking-datetime" ["value"]=> string(10) "1634601600" ["type"]=> string(7) "NUMERIC" ["compare"]=> string(1) "=" }
array(4) { ["key"]=> string(19) "wpcf-trial-location" ["value"]=> string(3) "155" ["type"]=> string(7) "NUMERIC" ["compare"]=> string(1) "=" } string(3) "AND"
array(4) { ["key"]=> string(21) "wpcf-booking-datetime" ["value"]=> string(10) "1634601600" ["type"]=> string(7) "NUMERIC" ["compare"]=> string(1) "=" }
array(4) { ["key"]=> string(19) "wpcf-trial-location" ["value"]=> string(3) "155" ["type"]=> string(7) "NUMERIC" ["compare"]=> string(1) "=" } string(3) "AND"

Hello,

Well its clear that there is a Key attribute in the array, it appears that we may be looking in the wrong place.

Can you paste the entire error that shows the line number where the fault is being thrown ?

This will help to pinpoint exactly where we should be looking.

Thanks,
Shane

Hello,

I will need to physically interact with the site to understand what line 605 is saying with the context of the entire file.

Would it be possible to get admin access to the site as well as the link to the page where this code is triggered?

Thanks,
Shane

[Puntorosso]

Found the solution.
The error is triggered because $value can return an empty array and $target_field is always a string value in foreach.
In this case we need to prevent the comparison by changing the line

if ( $value['key'] == $target_field){ 

to

if ( isset ( $value['key']  ) && $value['key'] == $target_field){ 

Thanks for your help. Best.
