in your you view,
<tr>
<?php $valuesub = ($page->subcat_recip_id); ?>
<?php $array_of_values = explode(",", $valuesub);
foreach ($array_of_values as $item) {
if(in_array($subcat_recip_id,$item)): { ?>
<td>
<input type="checkbox" name="subcat_recip_id[]" class="square-purple" value="<?php echo html_escape($item["title"]); ?>" CHECKED> <?php echo html_escape($item["title"]);
} ?>
<?php else: { ?>
<input type="checkbox" name="subcat_recip_id[]" class="square-purple" value="<?php echo html_escape($item["title"]); ?>"> <?php echo html_escape($item["title"]);
}
endif; }?>
</td>
<?php echo html_escape($valuesub); ?>
</tr>
change to :
<tr>
<?php $valuesub = ($page->subcat_recip_id);
$array_of_values = explode(",", $valuesub); ?>
<td>
<?php foreach ($array_of_values as $item) :?>
<input type="checkbox" name="subcat_recip_id[]" class="square-purple" value="<?php echo html_escape($item["title"]); ?>" <?=(in_array($subcat_recip_id,$item))?"CHECKED":""?>> <?=html_escape($item["title"]);?>'
<?php endforeach; ?>
</td>
<?=html_escape($valuesub)?>
</tr>
in model :
public function update($id){
//set values
$data = $this->page_model->input_values();
if (empty($data["slug"])) {
//slug for title
$data["slug"] = str_slug($data["title"]);
if (empty($data["slug"])) {
$data["slug"] = "page-" . uniqid();
}
}
$page = $this->get_page_by_id($id);
if (!empty($page)) {
$this->db->where('id', $id);
return $this->db->update('pages', $data);
}
return false;
}
change to :
public function update($id){
$data = $this->input_values();
if (empty($data["slug"])) {
$data["slug"] = str_slug($data["title"]);
if (empty($data["slug"])) {
$data["slug"] = "page-" . uniqid();
}
}
$page = $this->get_page_by_id($id);
if (!empty($page)) {
$this->db->where('id', $id);
return $this->db->update('pages', $data);
}
return false;
}
please update if you getting error,
tq

Answer 2

Well, it remains a bug but with some changes yr last code works. The great problem is the loop, it re-load the $valuesub for how many times is the value. Ie. If the array is composed of three values, it reads three times the same value. Pls see the two screenshots: https://www.screencast.com/t/MfiEDhdFuX
I can't get this loop off !!
Code
<td>
<?php foreach ($menu_links as $item) :
$valuesub = ($page->subcat_recip_id);
$array_of_values = explode("," , $valuesub);
if ($item['parent_id'] != "0" && $item['subcat_recip_id'] == "0") :
foreach($array_of_values as $dt): ?>
<?php //if(in_array($dt,$item)): ?>
<input type="checkbox" name="subcat_recip_id" class="square-purple" value="<?php echo html_escape($item["title"]); ?>" <?=(in_array($dt,$item))?"CHECKED":""?>> <?=html_escape($item["title"]);?>
<?php endforeach; endif;?>
<?php endforeach; ?>
</td><?php echo html_escape($valuesub); ?>
