Hack to customize the custom fields

[esm]

INDEXU does an efficient job of processing the custom fields for the link search form and making them available for input during the search process.
However, customizing those custom fields is another matter.

Why customize the custom fields? The primary reason is for select statements or radio buttons ( at least for me ). I have several Yes/No fields and I would like to use radio buttons.

Also, some of my custom fields have several options to chose from. For example, I might have a dropdown list with 5 or six options to choose from.

Here is a hack to customize those fields. Or at least get you started.

The first thing you should know is that if you go elect to do this, it will be a manual process. If you want the custom fields to show up you will manually have to add them ( but see below ).

This hack deals with the link_search process from the Admin screen.

In search_link_form.html

just before

<%custom_field_form%>

add the following

<tr class=tbl_light>
  <td>Show Detail</td>
  <td><%show_det%></td>
</tr>
<tr class=tbl_light2>
  <td>Business Type</td>
  <td><%bsn_type%></td>
</tr>

In the ShowFormSearchLink function of the link_search.php file:

After

global $category,$custom_field_form;

Add the following

// mod to allow customization of the custom fields
  global $show_det, $bsn_type;

Change

  $custom_field_form = $links_obj->GenerateCustomFieldForm();

to

  $custom_field_form = $links_obj->GenerateCustomizedField();

Change

DisplayTemplate($admin_template_path."link_search_form.html","\$category,\$custom_field_form");

to

  $show_det = ShowRadioButton ("show_detail","Yes,No","1,0","");
  $bsn_type = ShowDropDown ("bsn_type","---,Free,Commercial,Enhanced","3,2,1,0","");
// mod to allow customization of the custom fields
  DisplayTemplate($admin_template_path."link_search_form.html","\$category,\$custom_field_form,\$show_det,\$bsn_type");

Then in the ProcessFormSearchLink() function:

Just before

   elseif(!empty($$field))
      $query .= "and $field like '%".$$field."%' ";

add

// mod to allow customization of the custom fields
    elseif($field=='show_detail' && $show_detail<>"")
			$query .= " and $field = $show_detail ";
// mod to allow customization of the custom fields
    elseif($field=='bsn_type' && $bsn_type<>"")
			$query .= " and $field = $show_detail ";

Then change the following

$links_obj->more_param = "&pflag=search&link_id=$link_id&title=$title&url=$url&description=$description
&cat=$cat&contact_name=$contact_name&email=$email&show_detail=$show_detail&bsn_type=$bsn_type.$custom_field_param";

Finally, change the following:

  DisplayTemplate($admin_template_path."link_search_result.html",
    "\$num_rows,\$pagination,\$link,\$param,\$show_detail,\$bsn_type");

Then in link.class.php copy the GenerateCustomFieldForm function and paste it just before the very last } at the end of the link.class.php document. Rename it GenerateCustomizedField.

Just after the following,

$field = $fields[$i];
      global $$field;

Insert

if($field == 'show_detail' or $field == 'paid_thru'){}
else{

Several lines down, just before

$i++;

insert a

}

For each custom variable, you will follow the same process:
Add it to the link_search_results.html
add it to the ShowFormSearchLink in link_search.php
add it to the ProcessFormSearchLink link_search.php
add it to the new GenerateCustomizedField function in link.class.php

I have edit this from the original to show how to use the automatic generation of all other custom fields.

Thanks esm, this is another solutions from the one written in techical notes (under title: creating radio button and drop down menu).

Yep, I saw that in one of your posts the other day AFTER I had posted this. I may still finish it up as I need it in the link_search module.

Do you have any suggestions?

I have updated the hack to allow the use of the autogenerate feature.
