Have two record fields, cat_1_credits and cat_2_credits,  that I am totalling separately and have the totals appear in a column heading over the specific record column, am using this

<?php
$sum = 0;
foreach ($basketRecords as $record) {
$sum = $sum + $record['price'];
}
?>
The total price is: <?php echo $sum ?>

that I got from a 2014 thread https://www.interactivetools.com/forum/forum-posts.php?postNum=2233851#post2233851

I just replace basketRecords with my table name and price with  (record) name - it works great and provides the totals but if one of the records (cat_1_credits or cat_2_credits) has an empty entry I still get the correct total but this as well An unexpected error occurred:

How do I fix this?

Hi dmn,

Could you copy the code you're currently using that is producing the error? 

Thanks!

Hi,

Don't know if it will work but you can try a @ before the $ in the variable that comes up in the error report. That might suppress the error.

Or have a look at https://www.interactivetools.com/forum/forum-posts.php?postNum=2245823 which is about suppressing errors

Here it is Daniel, it's a search by date attended (min and max), for past records of 2 fields, cat_1_credits and cat_2_credits, it returns all the fields fine, with correct rows and columns, and you will the see sum value in the header of the tables, it does total them correctly but if one of the fields of either cat-1-credits or cat_2_credits, is empty there  is an error appears(eg.(An unexpected error occurred: #8691)) before the total being created by the empty field, the sum equation doesn't account for null values. I've searched the forum and online to try and account for null or empty fields but can't get anything to work.

I'm now looking at forcing default values using this script  from this forum thread https://www.interactivetools.com/forum/forum-posts.php?postNum=2231209#post2231209

 // load records from 'blog'
  list($blogs, $blogMetaData) = getRecords(array(
    'tableName'   => 'blog',
    'loadUploads' => true,
    'allowSearch' => false,
  ));

  foreach($blogs as $blog){
    echo "Checking record ".$blog['num']." <br>";
    if($blog['title'] == "test"){
      mysql_update('blog', $blog['num'], null, array('title' => 'Default Title'));
    }
  }
  echo "Script Complete";

Thanks Jerry from that forum thread I used error_reporting(0);

like this 

list($expiredEducationRecords, $education_recordsMetaData) = getRecords(array(
'tableName' => 'education_records',
'where' => "`createdByUserNum` = {$CURRENT_USER['num']}",
'allowSearch' => true,
'requireSearchMatch' => true,
));
error_reporting(0);

it worked no more errors showing.

Again, thanks very much for the insight.

Glad it worked for you

Excellent, works great, thank you Daniel.

By dmn - February 15, 2022

Daniel 

using this

$sum = $sum + intval($record['cat_1_credits']);

resolved the empty fields but I have records that have decimals (eg 5.5) where the decimal figure does not get added.

By daniel - February 15, 2022

Hey dmn,

Apologies, I didn't consider decimals! Instead of intval() you should be able to use floatval() in the same way:

$sum = $sum + floatval($record['cat_1_credits']);

Let me know if you have any other issues.

Thanks,

Daniel
