Plugin: Execute PHP Code

I'm still reluctant to include any kind of eval based plugins for three reasons:

1. It's dead simple to write plugins.
2. eval() is slow and this could potentially be running thousands of times per import.
3. Nasty security implications.

As far as the code, wouldn't it make more sense to offer the replacement patterns as $variables inside the eval?

How do you use replacement patterns?
I tried to insert them into php code, but it's not working.

I try this plugin and get error

Возникла AJAX HTTP ошибка. Полученный код HTTP: 500 Следует отладочная информация. Путь: /batch?id=1416&op=do СтатусТекст: Internal Server Error ResponseText:

this code i set to eval php textarea

<?php
return strtolower([cat1_description]);

?>

What i doing wrong?

it works for me

спасибо за плагин товарищам

This doesn't quite work for my user case. In my case, I have an existing node that is being updated by feeds. The node has a multivalue field with a couple of values already set. When the feed runs I want to append any new values from the feed file to the multivalue field on the existing node, as additional values.

To do that, I need a way of accessing the node that is being updated and/or the field that is being updated so that I can grab the existing values, and merge them with the values in the feed.

I actually have this working now, with the following code in the php tamper rule, and then an explode rule after it. I had to make one modification to the code to get it to work with cvs imports, which was to run the replacement patterns through strtolower. same issue as in #1263718: Rewrite plugin fails when tokens contain upper case letters

<?php
$skus = array();

// Load the node based on title
$query = new EntityFieldQuery;
$result = $query
  ->entityCondition('entity_type', 'node')
  ->propertyCondition('type', 'optics_frame_product_display')
  ->propertyCondition('title', '[Frame Description]')
  ->execute();

if (!empty($result['node'])) {
  $nodes = node_load_multiple(array_keys($result['node']));
  $node = current($nodes);
  foreach ($node->field_product['und'] as $key => $val) {
    $product = commerce_product_load($node->field_product['und'][$key]['product_id']);
    $skus[] = $product->sku;
  }
}
$skus[] = '[Crown SKU]';
$skus = array_unique($skus);
watchdog('test', print_r($skus, 1));
return implode(',', $skus);
?>

I applied this patch to feeds_tamper. It seems to work for executing isolated php code, but in my case I need to modify the value of that mapper element. Like mentioned above, I tried using the replacement patterns provided, but they don't seem to be replaced. I also tried dpm(get_defined_vars()); with the devel module, but only some global configuration variables are available.

I think this patch needs work to be able to execute code on the mapper element value. Correct me if I missing how to do this, please!

I think for this, we should add some access control e.g.:

$access = user_access('use PHP for settings');

As it would be security risk for roles which has give the access to manage feeds.

here the module https://drupal.org/project/feeds_tamper_php

This has a module now, so marking as fixed.
