Make your own banner Twister

Make functionality that will allow you to:

1. One place to store all of the banners
2. To set the page on which the banner will be shown
3. To comply with the limit display
4. To specify a banner for the destination address (URL)

Be sure to work on 0.9.6.3 (version does not portend problems), time integration should take about a half hour depending on your expertise when working with MODx.

the Necessary entry-level skills in MODx and understanding of the terms: snippet (snippet) TV in the context of this CMF.


All substantive questions will answer with pleasure.

Let's start:
Divide the whole integration in a few steps:

1. Create snippet Banner

<?php
if (!function_exists('setTemplateVar')) {
function setTemplateVar($value, $docID, $tplVarName) {
global $modx;

//-- get tmplvar id
$tplName = $modx- > getFullTableName('site_tmplvars');
$tplRS = $modx->db->select('id' $tplName 'name="' . $tplVarName . '"');
$tplRow = $modx->db->getRow($tplRS);

$tblName = $modx- > getFullTableName('site_tmplvar_contentvalues');

$selectQuery = $modx->db->select('*' $tblName 'contentid=' . $docID . ' AND tmplvarid=' . $tplRow['id']);

$updFields = array (
'value' => $value
);
$insFields = array (
'tmplvarid' => $tplRow['id']
'contentid' => $docID
'value' => $value
);

if ($modx->db->getRecordCount($selectQuery) < 1) {
$modx->db->insert($insFields, $tblName);
} else {
$modx->db->update($updFields, $tblName 'contentid=' . $docID . ' AND tmplvarid=' . $tplRow['id']);
}
}
}

/**/

$vault = 234;//ID of the branch with banners

$children= $modx- > getActiveChildren($vault, 'menuindex' 'ASC');
if (!$children === false) {

$allBanners = $modx- > getDocumentChildrenTVarOutput($vault, array('pages''fileBanner''counter''linkToURL'));

foreach($allBanners as $idBannerPage=>$banner)
{
$pages = explode(',',$banner['pages']);
if((in_array($modx- > documentIdentifier,$pages) || in_array('-1',$pages)) && ($banner['counter']>0 || $banner['counter'] == '-1'))
{
$path_info = pathinfo(MODX_BASE_PATH.$banner['fileBanner']);
switch($path_info['extension']){
case 'swf'
echo '
<div id="productsSecondaryPromo"></div>
<script type="text/javascript">
// <![CDATA[
var so = new SWFObject("/'.$banner['fileBanner'].'?clickTag='.$banner['linkToURL'].'", "company_right", "214", "308", "7", "#FFFFFF");
so.write("productsSecondaryPromo");
// ]]>
</script>';break;
default echo '<a href="'.$banner['linkToURL'].'"><img src="'.$modx->getConfig('base_url').$banner['fileBanner'].'" alt="" border="0"></a>';

}
if($banner['counter'] !== '-1' && (int)$banner['counter']>0){ setTemplateVar($banner['counter']-1, $idBannerPage, 'counter');}
}
unset($banner);
}
}
?>

2. Create the following TV settings (all that I have not mentioned below, leave default):

counter, in the drop-down list of "input Type" select the Number. The default value is exhibited -1. Choose a template. Save.

fileBanner, in the drop-down list of "input Type" choose File. Choose a template. Save.
linkToURL, in the drop-down list of "input Type" select the URL. Choose a template. Save.

pages, in the drop-down list of "input Type" select the Listbox (Multi-Select). In the field "Possible values", you write: @SELECT pagetitle,CONCAT(id,',') FROM site_content WHERE id NOT IN (2,3,4,5,6,7,8,9,10,11,234) ORDER BY menuindex
The default value is exhibited -1. Choose a template. Save.

3. Creating store banners

Now go to the document tree and create a new document with the name "BANNERS", set the checkbox on "Container (contains child documents)". Now locate in your code snippet the variable $vault and assign it the ID of the newly created document (the container).

In my case it is ID 234


Then add a child document — this is the essence of the banner at the bottom of the document should be visible to the new fields that we created earlier.



*If the "number of impressions ..." to change from -1 to a positive integer, then the banner will be shown to the equivalent of that number. With other fields I think everything is clear, if not ask.
*If the document to remove the activity through the context menu MODx, banner will not be displayed
*If you do not select the page, the banner is shown on all pages of the website
*Don't forget to download the banner :)

4. Now insert the snippet [[Banner]] in the place where you want to display the banner.

PS: this solution is quite scalable, you can modify it.
