Where are footer variable defined in opencart? - php

Question

I am trying to edit the link to one of the items in the footer in the following tpl file:
<?php if ($informations) : ?>
<div class="col-lg-4 col-md-4 col-xs-6">
<div class="module clearfix">
<h3 class="modtitle"><?php echo $text_information; ?></h3>
<div class="modcontent" >
<ul class="menu">
<?php foreach ($informations as $information) { ?>
<li><?php echo $information['title']; ?></li>
<?php } ?>
</ul>
</div>
</div>
</div>
it seems that they are looping through an array i guess where it says foreach ($informations as $information) { ?, where should i find $informations variable or how can i access the content of these variables?

Answer 1

The $informations defined in this file:
catalog/controller/common/footer.php
line 25, Opencart 2.2.0.0
this part:
$data['informations'] = array();
foreach ($this->model_catalog_information->getInformations() as $result) {
if ($result['bottom']) {
$data['informations'][] = array(
'title' => $result['title'],
'href' => $this->url->link('information/information', 'information_id=' . $result['information_id'])
);
}
}
how can i access the content of these variables?
When you create or edit an information page in admin panel, there's a checkbox labeled Bottom, if you check this option, this information page will be in $informations array.
If you trying to change a link via code, you can modify above code:
foreach ($this->model_catalog_information->getInformations() as $result) {
if ($result['bottom']) {
if($result['title'] == 'About Us'){
$link = "myCustomLink";
} else {
$link = $this->url->link('information/information', 'information_id=' . $result['information_id']);
}
$data['informations'][] = array(
'title' => $result['title'],
'href' => $link
);
}
}
Or by information id:
if($result['information_id'] == 4){
