用Feeds导入csv数据到Drupal 7中

补充：Drupal 7从7.12升级到7.15并且feeds也升级后，数据库结构发生了变化，以前的text可以直接编辑，现在的blob无法直接编辑，可以直接把feeds_source中的中断的项整个删除，然后重新添加导入就可以。

Drupal 7下feeds-7.x-2.0-alpha8导入csv文件时，为0的值不能导入文本字段，修改modules/feeds/mappers/text.inc:

function text_feeds_set_target($source, $entity, $target, $value) {
//jamesqi2013-11-15 if (empty($value)) {
if (empty($value) && $value!=='0') {
return;
}
这样0就不会被跳过了，可以导入。

geonamebase.com系列站2013年8月导入时遇到无head的csv文件字段对应的问题，通过搜索资料修改sites/all/modules/feeds/feeds_ui.admin.inc 可以解决：

/**
* Validation handler for feeds_ui_mapping_form().
*/
function feeds_ui_mapping_form_validate($form, &$form_state) {
//jamesqi2013-8-9 if (empty($form_state['values']['source']) xor empty($form_state['values']['target'])) {
if ((empty($form_state['values']['source']) && !is_numeric($form_state['values']['source'])) xor empty($form_state['values']['target'])) {
// Check triggering_element here so we can react differently for ajax
// submissions.
switch ($form_state['triggering_element']['#name']) {

// Regular form submission.
case 'op':
//jamesqi2013-8-9 if (empty($form_state['values']['source'])) {
if (empty($form_state['values']['source']) && !is_numeric($form_state['values']['source'])) {
form_error($form['source'], t('You must select a mapping source.'));
}
else {
form_error($form['target'], t('You must select a mapping target.'));
}
break;

$processor->addConfig(array('mappings' => $mappings));

//jamesqi2013-8-9 if (!empty($form_state['values']['source']) && !empty($form_state['values']['target'])) {
if ((!empty($form_state['values']['source']) || is_numeric($form_state['values']['source'])) && !empty($form_state['values']['target'])) {
try {
$mappings = $processor->getMappings();
$mappings[] = array(
'source' => $form_state['values']['source'],
'target' => $form_state['values']['target'],
'unique' => FALSE,
);
