/*
* ITFlow - Export helpers
*
* Shared plumbing behind the list page export modals:
* - a per-export column registry (label, source field, formatting, default state)
* - the column picker that every export modal renders
* - the CSV and PDF writers
*
* Handlers keep owning their own filter parsing and SQL. They hand rows over one
* at a time, in the same loop the old fputcsv() call sat in:
*
* $export = beginExport('assets', $_POST['export_assets'], "$file_name_prepend" . 'Assets', 'Assets', $filter_summary);
* while ($row = mysqli_fetch_assoc($sql)) {
* addExportRow($export, $row);
* }
* finishExport($export);
*
* A column's 'field' is just a key on the row array handed to addExportRow(), so a
* handler that needs a computed value (a prefixed number, a decrypted secret, a
* status word) sets that key on $row before the call - see getExportColumns() notes.
*/
// PDF is a read-and-print format, not a bulk transport. Past this many rows TCPDF's
// HTML table builder gets slow enough to walk into max_execution_time, so the
// handlers bounce the request back to CSV instead of timing out mid-download.
DEFINE("EXPORT_PDF_MAX_ROWS", 2000);
/*
* The column registry - one entry per export, in the order columns should appear.
*
* 'label' Column heading in the CSV / PDF.
* 'field' Key on the row array. Defaults to the column key itself.
* 'format' '' (raw), 'phone', 'money', 'number'. Only affects presentation.
* 'default' false to leave the box unticked when the modal opens. Defaults true.
* 'weight' Relative PDF column width, default 1. Bump it for long free text.
*
* Column keys are what the modal posts back, so they are whitelisted against this
* registry on the way in - an unknown key is dropped, not queried.
