Advanced Search - customized product fields?

[marco22]

Hi Ajeh and Zvenson,

I'm having some similar problem with advanced search.

I've added a field called "products_author" in "products" table, and now I'm trying to edit the advanced search adding the research also in this new field.

Until now I have no result, I've looked for tutorials or hints on the web, but I can't find... can u give me some help, please?

Thank u very much,
Marco

[zvenson]

sure - what did you do til now?
The main two files to edit are theses two
/include/modules/pages/advanced_search_results/header_php.php
/include/modules/pages/advanced_search/header_php.php

and of course the template for the search site...

i think in this thread there is all the information you need, but not nicely structured - so if you post your changes to the 2 files above i`ll have a look at it!

Hi Zvenson,

Thanks for the quick answer.

Actually I'm stucked, I understand that the answer I was looking for is in this thread but I can't extract it (as you said, you write during the process, so is not linear). Consider also that usually I work with xhtml, css and wordpress, so I'm not good in php.

Your case is different from mine because you have to search in new tables with new fields, while in my case I've to search in a new field (products_author) of an existing table (products).

It's not yet useful sending u my code because after some wrong attempts I bring back the code to the original.

If you have the time and the patience to show me how to procede, I'll be very grateful.

- sorry for that - but unfortunately this forum only allows edits 7 minutes after posting :) - and it`s not a tutorial ...

while in my case I've to search in a new field (products_author) of an existing table (products).

Is this just a simple text input field where you type in some name and it looks this up in the database?


First you have to add a field to the advanced search form. Edit:

/includes/templates/YOUR-TEMPLATE/templates/tpl_advanced_search_default.php file

and add something like this:

  <div class="centeredContent"><?php echo zen_draw_input_field('YOUR_NEW_FIELD', $sData['your_new_field'], 'onfocus="RemoveFormatString(this, \'' . KEYWORD_FORMAT_STRING . '\')"'); ?>

where you want the new field to appear in the search form.

Then edit the
/include/modules/pages/advanced_search/header_php.php

to "GET" the data from the field by adding something like this:

  $your_new_field =      (isset($_GET['your_new_field'])   ? zen_output_string($_GET['your_new_field']) : '');

now you just (okay, this is the tricky part) need to tell zen-cart to search the new data when something is submitted:
edit:
/include/modules/pages/advanced_search_results/header_php.php

(look for similar looking lines to paste this somewhere in between)
(isset($_GET['your_new_field']) && !is_string($_GET['your_new_field'])) &&

(same thing here: look for similar lines and just paste:
  if (isset($_GET['your_new_field'])) {
    $your_new_field = $_GET['your_new_field'];
  }

(now search for "if (empty($dfrom)" and add somewhere between the &&empty something like this:)
&& empty($your_new_field)

(search for similar and past:)
case 'YOUR_NEW_FIELD':
    $select_column_list .= 'p.your_fieldname_in_db';
    break;

(search for similar lines and paste:)
if (isset($_GET['your_new_field']) && zen_not_null($_GET['your_new_field'])) {
  $where_str .= " AND p.your_new_fielname_inDB = :yourfieldnameID";
  $where_str = $db->bindVars($where_str, ':yourfieldnameID', $_GET['your_field_name'], 'string');
}

of course you have to change your_field_name to the variable you want to search and change your_new_fildname_inDB as well.


well this should be it - but i`m totally not sure - im the trial and error kind as well :) just try it and tell me when you succeed - hope it helps somehow...

Thanks for the detailed answer!
I've done the process but it doesn't work yet...

/tpl_advanced_search_default.php file

1) Ok, I've added:

<div class="centeredContent"><?php echo zen_draw_input_field('PRODUCTS_AUTHOR', $sData['products_author'], 'onfocus="RemoveFormatString(this, \'' . KEYWORD_FORMAT_STRING . '\')"'); ?>

/include/modules/pages/advanced_search/header_php.php

2) Ok, I've added:

 $sData['products_author'] = (isset($_GET['products_author'])   ? zen_output_string($_GET['products_author']) : '');

/include/modules/pages/advanced_search_results/header_php.php

3) added:

(isset($_GET['products_author']) && !is_string($_GET['products_author'])) &&

4) added

if (isset($_GET['products_author'])) {
    $your_new_field = $_GET['products_author'];
  }

5) added

&& empty($products_author)

6) added

case 'PRODUCT_LIST_AUTHOR':
    $select_column_list .= 'p.products_author';
    break;

7) added, but I'm not sure about the ID part...

if (isset($_GET['products_author']) && zen_not_null($_GET['products_author'])) {
  $where_str .= " AND p.products_author = :productsauthorID";
  $where_str = $db->bindVars($where_str, ':productsauthorID', $_GET['products_author'], 'string');
}

Where I'm wrong?

[zvenson]

would be nice if you would tell us what happens when you start the search. This would make things much easier - maybe you can .provide a link

[marco22]

Actually I'm testing locally, I haven't put it on the web yet. As soon as I put it I'll tell you.

Thanks,
Marco

[zvenson]

well - you can tell us what the error message is - or what happens when you search - "it doesn`t work" is in most cases not helpful at all - but it`s not aleways necessary to upload the site to the web...
