====== out.php Parameters ======
 
Standard Set of Options

Basic Link
Sends to Trade

  /out.php?link=something

Send to a specific trade (click will be counted as a click on the trade)
  /out.php?member=trade1.com
  /out.php?member=trade1.com&url=http://trade1.com/nichepage.html

Permanent Link
  /out.php?link=something&url=http://realcontent.com
(With such a link, the surfer will always get to the content, unless otherwise specified in Default Skimming or Trader Personal Skimming)

The link=something parameter is not required. This is link tracking. For example, you have 2 blocks of thumbs on your homepage - one on the left, one on the right, and you want to know which one gets more clicks. We add &link=left to all out links in the left block, &link=right to the right block. After that, in Trade-> Statistics -> Links you can see how many clicks went through which link. This way you can evaluate which block is more clickable.

**Skimming** (redirecting some clicks to traders instead of content):
```
/out.php?link=something&url=http://realcontent.com&p=60
```

The `p=60` means 60% of clicks go to the URL; the remaining 40% go to traders (unless overridden in settings).

**Groups**:
```
/out.php?link=something&url=http://realcontent.com&p=60&group=teens
```

60% of clicks go to the URL; 40% go to traders from the "teens" group only.

Additional parameters:
- `&p_group=60` - Send 60% to a specific group; remaining clicks go to all groups
- `&skip_sell=true` - Don't apply Traffic Sell to this click
- `&dont_count_in_trade=true` - Don't count this click toward trader stats
  

===== TDS parameters =====
  
out.php?scheme_id= for distributing traffic according to the specified scheme


===== How to pass GET parameters =====

Pass extra parameters using the syntax `{parameter_name}`.

For example, a visitor clicks `out.php?link=my_super_ad` and you want to notify the trader which link was clicked. Create trader URLs like:

```
http://trader.com/?user_click_at={GET_link}
```

The click forwards to: `http://trader.com/?user_click_at=my_super_ad`


**Practical example**: Create a template like:

```html
<thumb ...>
  <a href="out.php?thumb_click_url=<!--THUMB_URL-->">
    <img src='<!--THUMB_URL-->'>
  </a>
</thumb>
```

Then create trader URLs like:

```
http://trader.com/?user_clicked_at={GET_thumb_click_url}
```

Note `thumb_click_url` appears in both places. When clicked, the link goes to `out.php?thumb_click_url=http://domain/thumb.jpg`, which forwards to the trader as `http://trader.com/?user_clicked_at=http://domain/thumb.jpg`.

You can also do this with JavaScript.


===== out.php and tube/index.php =====

out.php - this is redirects, click counting, etc.

tube/index.php - this only creates a site page

If you link to tube/index.php then the user will see a site page, but traffic counting, redirects etc will not work there and all parameters related to out will not work in this case.

all that out.php does - checks whether traffic needs to be redirected, counts it **AND** includes tube/index.php 


===== Rotation parameters =====

Default rotation looks like:

```
out.php?url=....&link=12x34x567
```

- `url` = gallery URL
- `link` = tracking parameter showing where the click came from (used to calculate thumb CTR)

For backward compatibility, this format still works. However, it shadows link-tracking (like `&link=block1`). To solve this, use `&link2` for your tracking, allowing both parameters simultaneously.

For internal pages, use `out.php?url=content`. You can combine all previous parameters with these:

- **&url=content** - For database lookups by parameter (slug, tag, category_name, etc.). Use this instead of a direct URL.
- **&group_id=, &group_name=** - Rotation group ID or name (defaults to content_list template)
- **&dont_count_in_trade=true** - Don't count toward trader stats (e.g., category clicks)
- **&dont_count_hit=true** - Don't count toward gallery CTR
- **&skip_to_cookie=true** - Don't increment the click counter for skimming calculations (useful for navigation clicks)
- **&slug=, &gallery_id=** - Gallery slug or ID (from gallery settings)
- **&send_to_source=true** - For custom galleries: forward to the source instead of displaying on your site
- **&force_template=** - Use a specific template
- **&force_lng=** - Force a language (en, de, etc.)
- **&sponsor_slug=, &sponsor_id** - Filter by sponsor
- **&model_id=, &model_slug=** - Filter by model
