need help with php arrays

Posted by ceci123 on February 23, 2011 at 7:45pm

I am trying to create a summary section/table "Printable Section for Interacting Medications" with the information stored on the "$variables['medication_name']" array.

I thought I could just do this "print $int_medication_name;" on the search-result.tpl.php page but it keeps looping and placing it after each result. I just don't understand how this works.

As shown below I have added a function phptemplate_preprocess_search_result () to the template.tpl.php file which gets displayed like this "print $medication_name;" on the search-result.tpl.php page.

template.tpl.php CODE

<?php
/** Grab field_designation and field_medication_name and place it into an array.*/
function phptemplate_preprocess_search_result (&$variables) {
  $result = $variables['result'];

$variables['designation'] = $result['node']->field_designation[0]['value'];

$variables['medication_name'] = $result['node']->field_medication_name[0]['value'];

}
?>

search-result.tpl.php CODE

<?php
// $Id: search-result.tpl.php,v 1.1.2.1 2008/08/28 08:21:44 dries Exp $

/**
 * @file search-result.tpl.php
 * Default theme implementation for displaying a single search result.
 *
 * This template renders a single search result and is collected into
 * search-results.tpl.php. This and the parent template are
 * dependent to one another sharing the markup for definition lists.
 *
 * Available variables:
 * - $url: URL of the result.
 * - $title: Title of the result.
 * - $snippet: A small preview of the result. Does not apply to user searches.
 * - $info: String of all the meta information ready for print. Does not apply
 *   to user searches.
 * - $info_split: Contains same data as $info, split into a keyed array.
 * - $type: The type of search, e.g., "node" or "user".
 *
 * Default keys within $info_split:
 * - $info_split['type']: Node type.
 * - $info_split['user']: Author of the node linked to users profile. Depends
 *   on permission.
 * - $info_split['date']: Last update of the node. Short formatted.
 * - $info_split['comment']: Number of comments output as "% comments", %
 *   being the count. Depends on comment.module.
 * - $info_split['upload']: Number of attachments output as "% attachments", %
 *   being the count. Depends on upload.module.
 *
 * Since $info_split is keyed, a direct print of the item is possible.
 * This array does not apply to user searches so it is recommended to check
 * for their existance before printing. The default keys of 'type', 'user' and
 * 'date' always exist for node searches. Modules may provide other data.
 *
 *   <?php if (isset($info_split['comment'])) : ?>
 *     <span class="info-comment">
 *       <?php print $info_split['comment']; ?>
 *     </span>
 *   <?php endif; ?>
 *
 * To check for all available data within $info_split, use the code below.
 *
 *   <?php print '<pre>'. check_plain(print_r($info_split, 1)) .'</pre>'; ?>
 *
 * @see template_preprocess_search_result()
 */
?>

Can anyone help?

Thank you in advance.

Your template file is

Posted by gbrands on February 23, 2011 at 8:56pm

Your template file is search-result.tpl.php. It acts on every single search result. In order to print the summary at the bottom you will have to modify search-results.tpl.php (notice the plural of results).

I learned something new

I learned something new today. Thanks.

So I took your advise and added this function (below) to template.tpl.php:

<?php
/** search results (not result) */
function phptemplate_preprocess_search_results(&$variables) {
  $result = $variables['result'];
  $variables['print_summary'] .= $result['node']->field_inter_medication_name[0]['value'];
}
?>

After that I tried to echo the results on the search-results.tpl.php file:

<?php
print $print_summary; 
?>

I don't see any results. What am I doing wrong? Can you give me an example of how to achieve this?

Thank you for your help.

Try setting your $result

Posted by gbrands on February 26, 2011 at 5:39am

Try setting your $result variable to the following:

<?php
$result = $variables['results'];
?>

Note that results is plural.

See template_preprocess_search_results() for more info.

$result array results data but am unable to print them.

Posted by ceci123 on February 27, 2011 at 5:56pm

As suggested I set the $result variable and when printing the array with print_r() returns the following.

<?php
/* the array is returning data... */
                     [field_inter_medication_name] => Array
                        (
                            [0] => Array
                                (
                                    [value] => carbamazepine 
                                    [safe] => carbamazepine 
                                )

                        )

                    [field_category] => Array
                        (
                            [0] => Array
                                (
                                    [value] => ARV
                                    [safe] => ARV
                                )

                        )

                    [field_medication_name] => Array
                        (
                            [0] => Array
                                (
                                    [value] => etravirine
                                    [safe] => etravirine
                                )

                        )
?>

The values are there but my problem is not being able to grab them using this function:

<?php
function phptemplate_preprocess_search_results(&$variables) {
  $result =  $variables['results'];
$variables['print_summary'] = $result['node']->field_inter_medication_name[0]['value'];
}
?>

Somehow the variable $print_summary is always empty when I tried printing on the search-results.tpl.php file.

I have a deadline coming soon and I must get this part working. Thank you for your help.

Thank you.

Can you post the results of

Posted by gbrands on February 27, 2011 at 6:09pm

Can you post the results of setting

<?php
 $variables['print_summary'] = '<pre>' . print_r($result,1) . '</pre>'; 
?>

. If that doesn't show anything how about setting it to the following:

<?php
 $variables['print_summary'] = 'HELLO!'; 
?>

If you don't get anything outputted from either of the two examples above are you sure you're clearing the template cache?

If I'm understanding the issue correctly, you need to process the result set as an array. Arrays cannot be assigned to/treated as scalar values.

This is done by iterating through the result set using the foreach php construct.

got it working!

Posted by ceci123 on February 27, 2011 at 8:41pm

I think I got it working...yeah!

I just did this:

<?php
function phptemplate_preprocess_search_results(&$variables) { 
  foreach ($variables['results'] as $result) {
    $variables['print_summary'] .= $result['node']->field_inter_medication_name[0]['value'].'<br>';} 
}
?>

Thanks for your help! I really appreciate it.
