Merge mutiple fields into one
Last modified: December 4, 2008 - 23:36
I have 2 option cck fields, one is a predefined list, the other is a text field. Both are set to unlimited number of values. I first tried to use array_merge, since it would be a more "elegant" solution; but I couldn't make it fly. This was my first attempt.
<?php
// set temp variable
$count = 0;
// put array into computed field array pt1
foreach (element_children($node->field_option) as $key) {
$node_field[$count]['value'] = $node->field_option[$key]['value'];
$count++;
}
// put array into computed field array pt2
foreach (element_children($node->field_option_list) as $key) {
$node_field[$count]['value'] = $node->field_option_list[$key]['value'];
$count++;
}
?>To make this into a comma separated list, here is the code. This works with "Store using the database", while the top one doesn't for some reason. This is what I'm using now
<?php
// set temp variable
$temp = array();
// put array into computed field array pt1
foreach (element_children($node->field_option) as $key) {
$temp[] = $node->field_option[$key]['value'];
}
// put array into computed field array pt2
foreach (element_children($node->field_option_list) as $key) {
$temp[] = $node->field_option_list[$key]['value'];
}
//kill empty values in the array
foreach ($temp as $key => $value) {
if (is_null($value) || $value=="") {
unset($temp[$key]);
}
}
//implode to comma list
$node_field[0]['value'] = implode(', ', $temp);
?>
Is there more going on here
Is there more going on here than meets the eye?
I know changing the field to your specific type (like
$node->field_YOURFIELDis required, but what else is needed to make this work?Right now, that code (both of them) don't do anything.... or at least I don't see it doing anything..
This is for combining 2
This is for combining 2 option fields. They both contain the same kind of data (text). Try it out with 2 option fields. I haven't tried this with mixed data types.
