Taxonomy Drop Down Select Jump Menu using Vocabulary and Terms for Navigation of Categories in a Block or Page
Here is a working 4.7.x version of a Taxonomy Select Menu snippet that you can use for a block, on a page, or wherever you can put some PHP on your site. Only 4 or 5 things you need to change in the code below:
1) Where it says $vid=1;, replace the number 1 with the vocabulary ID number for the vocabulary you want to use to populate the drop-down with the terms in that vocabulary.
2) Where it says $formname="Company";, replace the word Company with the word(s) you want your users to see as the default text in the drop-down after List by.
3) Optional: Where it says $options[] = t('List by ' . $formname);, replace List by with the word(s) you want at the beginning of the default text in the drop-down.
4) Where it says $options['http://www.example.com/taxonomy/term/'.$term->tid] = $term->name;, replace example.com with the URL of your drupal website.
5) Where it says return drupal_get_form('company_dropdown', $form);, replace the word company with the same word you used in step 2) above - these two text strings must match.
<?php
$vid=1;$formname="Company";
$vocabulary = db_query("SELECT term_data.name, term_data.tid FROM term_data WHERE term_data.vid=$vid ORDER BY name");
$options[] = t('List by ' . $formname); // Initialise the country array
//Populate array with url / name
while ($term = db_fetch_object($vocabulary)) {
$options['http://www.example.com/taxonomy/term/'.$term->tid] = $term->name;
}
//Build dropdown select
//If we try to build OnChange directly it gets mangled, so put in array to confuse the forms api
$form['category'] = array(
'#type' => 'select',
'#name' => $formname,
'#id' => $formname,
'#title' => '',
'#default_value' => '',
'#options' => $options,
'#description' => '',
'#multiple' => $multiple = FALSE,
'#required' => $required = FALSE,
'#attributes' => array('onChange' => "top.location.href=document.getElementById('$formname').options[document.getElementById('$formname').selectedIndex].value"),
);
//Output the form
return drupal_get_form('Company_dropdown', $form);
?>This is a result of the collaborative work on: http://drupal.org/node/48843 - you can see the development over there, and maybe get some questions answered. There is also a version that works with 4.6.x over there.
