I am trying to use hook_node_view() to replace, in the front page, <div>:placeholder1:</div> with the content of $string.

function mymodule_node_view(&$node, $view_mode, $langcode){
  $string = "I am here";
  $node->field_column_second['und'][0]['value']['#markup'] = array(
     '#markup' => str_replace(':placeholder1:', $string, $node->field_column_second['und'][0]['value'])
);

I also cleared Drupal cache, but I don't see any change.

What am I doing wrong?

  • Are you writing this snippet in mymodule.module with mymodule.info existing as well? – Jimmy Ko Jun 30 '16 at 10:01
  • Why do you think hook_node_view() would be invoked for the front page too. What did you set as front page? – kiamlaluno Jun 30 '16 at 11:32

  1. According to the doc, the first parameter should be $node, rather than &$node.
  2. The replacement code should look something like this: $node->content['body'][0]['#markup'] = str_replace($old, $new, $subject); so you missed [0] in your code, when in doubt, do a dsm($node) and check the variable you want.
  3. Complete code:

    function test_node_view($node, $view_mode, $langcode){ if (drupal_is_front_page()) { // check if necessary $string = "new"; $node->content['body'][0]['#markup'] = str_replace('old', $string, $node->content['body'][0]['#markup']); } //dsm($node); }

  • Can you please check, I edit my question. – Dev Jun 30 '16 at 8:44
  • Updated, I believe the value gets displayed comes from $node->content – cchen Jun 30 '16 at 13:16
