That’s super awesome, thank you! I’ll check out the plugins too.

Hi guys! I had this working beautifully – I invoked a function for a bunch of numerical Piklist fields, all coded similar to this:

piklist('field', array(
  'type' => 'text',
  'field' => 'surface_lifts',
  'label' =>  __('Surface Lifts'),
  'position' => 'wrap',
  'attributes' => array(
    'class' => 'text',
    'columns' => 2,
    'onFocus' => 'startCalc();',
    'onBlur' => 'stopCalc();'
  ) 
)); 

…and for the autosum field, I did this:

piklist('field', array(
  'type' => 'text',
  'field' => 'total_lifts',
  'label' =>  __('Total Lifts'),
  'position' => 'wrap',
  'attributes' => array(
    'class' => 'text',
    'columns' => 2,
    'readonly' => "readonly"
  ) 
));

and it used this JavaScript:

function calc(){

  lifts1 = document.post["post_meta[trams]"].value; 
  lifts2 = document.post["post_meta[gondolas]"].value; 
  lifts3 = document.post["post_meta[hs_sixpack]"].value;
  lifts4 = document.post["post_meta[hs_quad]"].value; 
  lifts5 = document.post["post_meta[hs_triple]"].value; 
  lifts6 = document.post["post_meta[quad_chairs]"].value; 
  lifts7 = document.post["post_meta[triple_chairs]"].value; 
  lifts8 = document.post["post_meta[double_chairs]"].value; 
  lifts9 = document.post["post_meta[surface_lifts]"].value; 
  document.post["post_meta[total_lifts]"].value = 
    (lifts1*1) 
  + (lifts2*1) 
  + (lifts3*1)
  + (lifts4*1)
  + (lifts5*1)
  + (lifts6*1)
  + (lifts7*1)
  + (lifts8*1)
  + (lifts9*1);
}

function startCalc(){
  interval = setInterval("calc()",1);
}

function stopCalc(){
  clearInterval(interval);
}

But after the move to the final server – plus a Piklist update – it doesn’t work. I get this error:

TypeError: ‘undefined’ is not an object (evaluating ‘document.post[“post_meta[trams]”].value’)

…implying it’s failing when trying to get the first value.

I apologize that my Javascript is pretty rudimentary, but I wanted to check with you guys in case it might be something to do with Piklist, or perhaps how I’m supposed to reference the metafield variables has changed…

Thanks!

It was 0.9.1. Not 100% sure that this feature was indeed working with that version as it didn’t come up as an issue till recently, but it seems to be the case. Currently on 0.9.3 on the new (final) server.

Thanks a million Marcus! I followed your instructions to the letter, AFAIK – and have confirmed that your script is loading – but I’m not seeing any auto-summing.

Here’s what I’ve done for the autosum fields in the metabox file:

piklist('field', array(
  'type' => 'text',
  'field' => 'calcme_trams',
  'label' =>  __('Trams'),
  'position' => 'wrap',
  'attributes' => array(
    'class' => 'text',
    'columns' => 2,
    'onFocus' => 'calcMe();'  ) 
)); 

…and here’s what i did for the grand-total field:

piklist('field', array(
  'type' => 'text',
  'field' => 'finalcalc_total_lifts',
  'label' =>  __('Total Lifts'),
  'position' => 'wrap',
  'attributes' => array(
    'class' => 'text',
    'columns' => 2,
    'readonly' => "readonly"
  ) 
)); 

But nothing happens.

Any idea what might be amiss?

Thanks again,
Adam

Hi again Marcus!

Hey, I realized that there was an unintended consequence in my using that fine JS code of yours. Since I had to rename the relevant metafields for the calc to work, all the data my client already entered in for those – in 130+ posts – is no longer being used or displayed. Well, the front end was OK, but only because it was grabbing the old fields.

Instead of making my client re-enter all those numbers, I’m wondering if the script could simply do a hard-coded calc of the needed fields, as they already are named, instead of the (admittedly efficient and nifty) approach of custom-naming the fields and using the “each” function.

Not pretty I know, but this field configuration is not going to change, and if it does, I’m happy to hard-code a fix.

Let me know… thanks!
Adam
