I developed a custom module in Drupal 7. I asked a similar question here: Drupal 7 Get field value by machine name and pass to javascript

But the difference in this question is, instead of a taxonomy term, I want to get the field value of a regular text field.

Here is the code that I use to get the field value of a taxonomy term to pass to javascript, which currently resides in my theme's hook_process_page function:

if ($node = menu_get_object('node')) { $tid = $node->field_test['und'][0]['tid']; $term = taxonomy_term_load($tid); drupal_add_js(array('mymodule' => array('test' => $term->name)), 'setting'); }

Some things that I can see might ned to be changed right away are "tid," "taxonomy_term_load."

How can I change this code to instead get the text value of a field instead of a taxonomy term, to pass to mymodule?

EDIT:

Per a suggested change, I've modified the code, though I'm not sure this is what was meant:

if ($node = menu_get_object('node')) { $fieldValue = $node->field_test['und'][0]['value']; $term = taxonomy_term_load($fieldValue); drupal_add_js(array('jsblock' => array('test' => $fieldValue->name)), 'setting'); }

The in response to Drupal.settings.jsblock.test, the console outputs null.

Here is the Drupal notice:

property of non-object

How can I get the field value and pass it to my jsblock module?

The suggestion you wrote for your code 

$fieldValue = $node->field_test['und'][0]['value']; $term = taxonomy_term_load($fieldValue);

If you require only value then your purpose gets solved at this line of code 

$fieldValue = $node->field_test['und'][0]['value'];

Secondly the function taxonomy_term_load() expects tid as parameter and you are sending a value string, hence it will throw an error. See the API document. https://api.drupal.org/api/drupal/modules!taxonomy!taxonomy.module/function/taxonomy_term_load/7.x

You should just send the variable to javascript file as this 

drupal_add_js(array('jsblock' => array('test' => $fieldValue)), 'setting');

For text fields you can use

$value = $node->field_my_field_name['und'][0]['value'];

or, if you want sanitized value, use ['safe_value'].

  • thanks for the answer! I updated my code in post post after "EDIT:" I'm still getting some errors. I'm not sure if I did what you meant. Any suggestions are appreciated. Commented Dec 17, 2017 at 21:02
  • in your modified/repurposed code, you no longer need $term = taxonomy_term_load($fieldValue);, and the error is a result of calling the "name" value of your variable, rather than the variable itself array('test' => $fieldValue) Commented Dec 17, 2017 at 21:22
  • Thank you to you also @Anson for clarifying the drupal_add_js function! Commented Dec 17, 2017 at 23:46

    Note: Using ['und'] will not work if you enable translation for that field. See Best practice for language key for “und” in hook_form_alter Commented Dec 18, 2017 at 7:19
