Strip HTML tags from Field Collections in Services Views

Question

I'm trying to strip the HTML tags from a JSON response I generated using Services Views, but I'm not having any luck so far. I have a content type with a Field Collections field in it that is outputting HTML tags no matter what I do. I've tried the following:

• Check Strip HTML tags in the field settings in the view
• Set customize field HTML to 'None'
• Set Customize field and label wrapper HTML to 'None'
• All combinations of the above
• Making sure to turn of all 'Provide default field wrapper elements' options

Am I missing anything? My output still looks like this in my json:

"Animals": [
            "<div class=\"entity entity-field-collection-item field-collection-item-field-product-animals clearfix\">\n  <div class=\"content\">\n    <div class=\"field field-name-field-product-animal field-type-taxonomy-term-reference field-label-above\"><div class=\"field-label\">Animal:&nbsp;</div><div class=\"field-items\"><div class=\"field-item even\">Big</div></div></div><div class=\"field field-name-field-product-withdrawal-time field-type-text field-label-above\"><div class=\"field-label\">Withdrawal time:&nbsp;</div><div class=\"field-items\"><div class=\"field-item even\">25 dg</div></div></div>  </div>\n</div>\n",
            "<div class=\"entity entity-field-collection-item field-collection-item-field-product-animals clearfix\">\n  <div class=\"content\">\n    <div class=\"field field-name-field-product-animal field-type-taxonomy-term-reference field-label-above\"><div class=\"field-label\">Animal:&nbsp;</div><div class=\"field-items\"><div class=\"field-item even\">Rund vlees</div></div></div><div class=\"field field-name-field-product-withdrawal-time field-type-text field-label-above\"><div class=\"field-label\">Withdrawal time:&nbsp;</div><div class=\"field-items\"><div class=\"field-item even\">21 dg</div></div></div>  </div>\n</div>\n",
            "<div class=\"entity entity-field-collection-item field-collection-item-field-product-animals clearfix\">\n  <div class=\"content\">\n    <div class=\"field field-name-field-product-animal field-type-taxonomy-term-reference field-label-above\"><div class=\"field-label\">Animal:&nbsp;</div><div class=\"field-items\"><div class=\"field-item even\">Pluimvee ei</div></div></div><div class=\"field field-name-field-product-withdrawal-time field-type-text field-label-above\"><div class=\"field-label\">Withdrawal time:&nbsp;</div><div class=\"field-items\"><div class=\"field-item even\">6 dg</div></div></div>  </div>\n</div>\n"

Any help on this is greatly appreciated.

Answer 1

You have to tell use what you have done so far.

To strip tags use strip_tags php code. This function takes two parameters:

string strip_tags ( string $str , [string $allowable_tags ] )

The first argument is the string and the optional second parameter is to specify tags which should not be stripped. For example

<?php
    echo strip_tags("Hello <b><i>world!</i></b>","<b>");
?>

Will output this

Hello world!

Not

Hello world!

I guess you have to use views_datasource module to generate JSON. I have already used this module and no default HTML tag were inserted by the View.

Did you try preprocess functions to strip the tags from the view?

Answer 2

You can override the output using hook_preprocess_HOOK and expose it into the variable, for example:

/**
 * Implements hook_preprocess_HOOK().
 */
function MYMODULE_preprocess_views_view_field(&$vars) {
  $view = $vars['view'];
  switch ($view->name) {
    case 'my_view':
      // @see: views-view-field--my-view--page--field-foo.tpl.php
      $node = entity_metadata_wrapper('node', $vars['row']->nid);
      $vars['value']  = '';

      foreach ($node->field_foo_collection->getIterator() as $item) {
        foreach ($item->field_multivalued as $value) {
          $vars['value'] .= '[ ' . $value . ' ], ';
        }
      }
    break;
  }
}

Then print the $value in your template file (e.g. views-view-field--my-view--page--field-foo.tpl.php), e.g.

<?= $value ?>
