[MOD-HELP] Icons for each category with admin control

[marcelocamargo]

Hello friends,

Firstly, sorry about my english...


1. I need to add a icon for each category. At here, easy  
2. The icon must be added or edited in panel control, by admin
3. It's like to submit a thumbnail from image, but in this case, the thumbnail will be linked to category, and must appear in "category_bit.html" like:

Code: [Select]



{if category_with_icon}
 <a href="{cat_url}"><img src="{cat_icon}"></a>
{endif category_with_icon}



How could I make this mod?
Anybody help me?

Thanks for all...

if u have a little PHP knowlege I could try explain how it can be done.
like, for the beginning, I'd use one extra (new) field in the 4images_categories table, to store "icon" information for each category.

[marcelocamargo]

Hello V@ano,


Yes... I have PHP knowlege...

The new field "icon" was added in 4images_categories table...
Now, the next step is to modify control panel, in "Add category" and "Edit category".

I will try to make this alone, but maybe I need your help

Thank you...

Hello friends,

This is my first attempt to make this modification...

See below all carried through alterations:

1. Objective

The objective of this modification is to leave the option to the administrator of the system to attribute an icon to a category. This resource is not obligator, and is the criterion of the administrator to use it or not.

2. Modifications in the Database

2.1. Modify the table 4_images_categories, adding to the new field cat_icon

SQL Command:

Code: [Select]

ALTER TABLE 'database_name'.'4images_categories' ADD 'cat_icon' VARCHAR(255);

3. Modifications in files

3.1. Modifications in file "admin/categories.php"

Search for:

Code: [Select]

if ($action == "addcat") {
  if ($msg != "") {
    printf("<b>%s</b>\n", $msg);
  }

  show_form_header("categories.php", "savecat");
  show_table_header($lang['nav_categories_add'], 2);
  show_input_row($lang['field_category_name'], "cat_name", "", $textinput_size);

Add below:

Code: [Select]

 show_upload_row($lang['thumb'], "thumb_file", "<br /><span class=smalltext>".$lang['allowed_mediatypes_desc']." jpg, gif, png</span>");

Search for:

Code: [Select]

if ($action == "savecat") {
  $error = array();
  $cat_name = un_htmlspecialchars(trim($HTTP_POST_VARS['cat_name']));
  $cat_description = un_htmlspecialchars(trim($HTTP_POST_VARS['cat_description']));
  $cat_parent_id = intval($HTTP_POST_VARS['cat_parent_id']);
  $cat_order = (isset($HTTP_POST_VARS['cat_order'])) ? intval($HTTP_POST_VARS['cat_order']) : 0;

  $auth_viewcat = $HTTP_POST_VARS['auth_viewcat'];
  $auth_viewimage = $HTTP_POST_VARS['auth_viewimage'];

4. Bugs

4.1. The file is not being sent for the folder

The reason it does that, because u need special attributies/instructions in the <FORM> I dont know exactly what could be wrong (I didnt install this mod) but try:
in /admin/categories.php find:

Code: [Select]

 show_form_header("categories.php", "savecat");
Replace with:

Code: [Select]

 show_form_header("categories.php", "savecat", "", 1);
it might will solve 4.2 bug as well

Code: [Select]

include(ROOT_PATH.'includes/upload.php');
$site_upload = new Upload();
