From c8af0fd7d1f68138d46106d40dcd602a261b7b9d Mon Sep 17 00:00:00 2001 From: Will Rossiter Date: Sat, 11 May 2013 18:05:53 +1200 Subject: [PATCH] FIX: If CSV column mapping maps to function, keep key value as key. Fixes http://open.silverstripe.org/ticket/6473 When using CSVParser::$columnMapping to map columns to a callback action, it previously used the action name as the key value. This prevented users from defining multiple entries to the same callback. This patch retains those key values and simply runs the callback field name filter later on. --- dev/CSVParser.php | 4 +-- dev/CsvBulkLoader.php | 48 ++++++++++++++++++++++++++------- tests/dev/CSVParserTest.php | 7 ++++- tests/dev/CsvBulkLoaderTest.php | 39 ++++++++++++++++++++++----- 4 files changed, 80 insertions(+), 18 deletions(-) diff --git a/dev/CSVParser.php b/dev/CSVParser.php index dca97649b..cee48e5d0 100644 --- a/dev/CSVParser.php +++ b/dev/CSVParser.php @@ -93,9 +93,11 @@ class CSVParser extends Object implements Iterator { public function mapColumns($columnMap) { if($columnMap) { $lowerColumnMap = array(); + foreach($columnMap as $k => $v) { $lowerColumnMap[strtolower($k)] = $v; } + $this->columnMap = array_merge($this->columnMap, $lowerColumnMap); } } @@ -230,7 +232,5 @@ class CSVParser extends Object implements Iterator { public function valid() { return $this->currentRow ? true : false; } - - } diff --git a/dev/CsvBulkLoader.php b/dev/CsvBulkLoader.php index d6ba98b7d..dae0f906c 100644 --- a/dev/CsvBulkLoader.php +++ b/dev/CsvBulkLoader.php @@ -27,7 +27,8 @@ class CsvBulkLoader extends BulkLoader { public $enclosure = '"'; /** - * Identifies if the has a header row. + * Identifies if csv the has a header row. + * * @var boolean */ public $hasHeaderRow = true; @@ -39,15 +40,37 @@ class CsvBulkLoader extends BulkLoader { return $this->processAll($filepath, true); } + /** + * @param string $filepath + * @param boolean $preview + */ protected function processAll($filepath, $preview = false) { $results = new BulkLoader_Result(); - $csv = new CSVParser($filepath, $this->delimiter, $this->enclosure); + $csv = new CSVParser( + $filepath, + $this->delimiter, + $this->enclosure + ); // ColumnMap has two uses, depending on whether hasHeaderRow is set if($this->columnMap) { - if($this->hasHeaderRow) $csv->mapColumns($this->columnMap); - else $csv->provideHeaderRow($this->columnMap); + // if the map goes to a callback, use the same key value as the map + // value, rather than function name as multiple keys may use the + // same callback + foreach($this->columnMap as $k => $v) { + if(strpos($v, "->") === 0) { + $map[$k] = $k; + } else { + $map[$k] = $v; + } + } + + if($this->hasHeaderRow) { + $csv->mapColumns($map); + } else { + $csv->provideHeaderRow($map); + } } foreach($csv as $row) { @@ -115,12 +138,19 @@ class CsvBulkLoader extends BulkLoader { } // second run: save data + foreach($record as $fieldName => $val) { - //break out of the loop if we are previewing - if ($preview) break; - if($this->isNullValue($val, $fieldName)) continue; - if(strpos($fieldName, '->') !== FALSE) { - $funcName = substr($fieldName, 2); + // break out of the loop if we are previewing + if ($preview) { + break; + } + + // look up the mapping to see if this needs to map to callback + $mapped = $this->columnMap && isset($this->columnMap[$fieldName]); + + if($mapped && strpos($this->columnMap[$fieldName], '->') === 0) { + $funcName = substr($this->columnMap[$fieldName], 2); + $this->$funcName($obj, $val, $record); } else if($obj->hasMethod("import{$fieldName}")) { $obj->{"import{$fieldName}"}($val, $record); diff --git a/tests/dev/CSVParserTest.php b/tests/dev/CSVParserTest.php index 6e1cae06b..2e41be05b 100644 --- a/tests/dev/CSVParserTest.php +++ b/tests/dev/CSVParserTest.php @@ -1,6 +1,12 @@ getCurrentRelativePath() .
