How to programmatically add a link to an image field in a view

Question

I have a view with an image field and other fields, and I need to link the rendered image, not the content which is one of the configuration choice, but on another computed filtered view. I think that I should use my_theme_preprocess_views_view_field_myviewname to catch this field, using it's name as selector then wrap it with the computed link, but didn't find how to do it.

To clarify my question, the image in this view is normally displayed, and I "dynamically" create a link to another view which is not related to the image. I wrote a function (in my template) to compute this link, and I need to know how to add this link to the image field within my_theme_preprocess_views_view_field_myviewname(&vars). The preprocess function is executed several times to build the view, I tried to use var_dump(vars) to see where is the image field, but it generates a too huge amount of data.

Answer 1

As per your question, I assume that you want the image link to open the image in existing/new tab. For this you can add a relationship of 'File Usage : File'.Post that you get the file path field in the fields section of the view. Add that file path field and in the rewrite result section or in template file you can create tag with the required image. PS: In field image setting select noting in link image to setting.

After some more search/tests and your help here is the solution I used to do it. In my theme template.php I added

function MyTHEME_preprocess_views_view_field__VIEWNAME__page(&$vars) {
  $view = $vars['view'];
  $field = $vars['field'];

  // field is an object of type views_handler_field_node

  if ((isset($field)) && ($field->field == 'my_image_field_name' )) {

     // create a string like <a href="" >
     $myLink = myFunctionToBuildLink($view);

     $vars['output'] = $myLink . $vars['output'] . '</a>';
  }
}

Now I have the right link to the specific view and page I wanted. The "__page" at the end of the function name is because I use a view with display page.
