[SOLVED] Foreach with implode comma

Sorry, but I do not understand what you are trying to achieve. Can you explain again? And what is going wrong exactly?

Thanks for your reply @PaulD. well what i wanted to achieve was to retrieve the selected checkboxes id(1,2 0r 4) then print their values from db using foreach and implode so it may look like: Love, Heaven, Sun.

If it's only about the text value, why don't you assign that as the value attribute of the checkbox?

PHP Code:

<input type="checkbox" name="check_list[]" value="love">love<br> 


If you need both the number and the text, I would suggest getting the id's and names from your database and put them into an array (in your controller):

PHP Code:

$info = array();
$query = $this->db->query("SELECT id,text_name FROM info");
foreach ($query->result() as $i) {
   $id = $i->id;
   $info[$id] = $i->text_name;
}
// result of this is: $info[1] = 'love', $info[2] = 'heart' etc.

$tags = $this->input->post('check_list');
$selected = array();
foreach ($tags as $t) {
    $selected[] = $info[$t];
}
$endresult = implode(',' , $selected);
// result of this: the "names" of the selected textboxes, seperated by comma's, so no comma after the last one. 


@Wouter60 your comment was good(the second php code section,that was what i wanted) but it came late as i already had a friend who showed me where i was wrong. here is my fix:

PHP Code:

$tags = $this->input->post('check_list');
       if (isset($tags)){
        $q = [];
             
            
            foreach($tags as $t){
                
                $q[] = $this->db->get_where('info', array('text_id' => $t))->result()->text_name;
                
            } 
}
 echo implode(", ", $q); // prints Love, Sun, Heaven 


Not good. I can change the content from check_list. I can spam the log or other funny stuff
