How do I access only second array? - php

Question

I'm doing this:
$sql_glassware = 'SELECT id, name FROM glassware';
$qry_glassware = $con->query($sql_glassware);
$get_glassware = $qry_glassware->fetchAll(PDO::FETCH_ASSOC);
debug($get_glassware);
debug() is a personal function; It returns the result like this:
$get_glassware = array(19) {
[0]=>array(2) {
["id"]=>string(1) "1"
["name"]=>string(8) "Cocktail"
}
[1]=>array(2) {
["id"]=>string(1) "2"
["name"]=>string(9) "Margarita"
}
[2]=>array(2) {
["id"]=>string(1) "3"
["name"]=>string(8) "Highball"
}
...
}
I'm guessing the first array level is the rows, and the second level is the columns.
don't know why it return the id as strings thoug...
Then I'm using a class to construct a complete form; I have a public function called addSelect() where the first argument takes an array of values to build the options list: array('name0','name1', 'name2','...') and do a foreach()-loop inside:
public function addSelect($opt=array(),$param=array())
$name = $this->useEither($param['name'],'dropdown-list'); // useEither() is a personal function
foreach ($opt as $val => $name){
$options .= '<option value="'.$val.'">'.$name.'</option>';
}
$select = '<select name="'.$name.'" '.$param['string'].'>'.$options.'</select>';
$this->formElements[] = $select; // store the list for use later
}
How can re-write this litte function so I can pass $get_glassware directly into my function first argument and have it output the options like this:
<option value="1">Cocktail</option>
<option value="2">Margarita</option>
<option value="3">Highball</option>

Answer 1

Try this:
public function addSelect($opt=array(),$param=array())
$name = $this->useEither($param['name'],'dropdown-list'); // useEither() is a personal function
foreach ($opt as $option){
$options .= '<option value="'.$option['id'].'">'.$option['name'].'</option>';
}
$select = '<select name="'.$name.'" '.$param['string'].'>'.$options.'</select>';
$this->formElements[] = $select; // store the list for use later
}

I'm not sure why or what do you want to do there but your foreach in addSelect overwrites the $name variable.
But as far as I understand your problem, that should do the trick for you.
foreach ($opt as $val => $name){
$options .= '<option value="' . $name['id'] . '">' . $name['name'] . '</option>';
}
For the debug function... usually print_r is easier to read instead of var_dump but for debugging maybe sometimes still necessary.
