Get array for dropdown from foreach parent - php

Question

I have 2 arrays (one inside the other), where one goes through a list of questions - and the other contains the list of options for the dropdown menu.
<?php foreach ($modelSettings as $name=>$item):?>
<select name="<?php echo 'model'.($i+1).'['.$name.']' ?>" >
<?php foreach($item['options'] as $value):?>
<option value="<?php echo $value?>"><?php echo ucfirst($value);?></option>
<?php endforeach;?>
</select>
<input type="hidden" name="<?php echo 'model'.($i+1).'[id]'?>" value="0"/>
<?php endforeach;?>
The result looks like this
<select name="model4[car]">
<option value="bmw">BMW</option>
<option value="toyota">Toyota</option>
<option value="volvo">Volvo</option>
</select>
<select name="model4[color]">
<option value="red">Red</option>
<option value="blue">Blue</option>
<option value="white">White</option>
</select>
What I'm trying to do is to eliminate the first foreach so that I will write up every <select> manually, but have the list in the dropdown retrieved via an array.
I've been trying various things, among them this:
<select name="model4[car]" >
<?php foreach ($modelSettings as $name=>$item):?>
<?php foreach($name[0] as $value):?>
<option value="<?php echo $value?>"><?php echo ucfirst($value);?></option>
<?php endforeach;?>
<?php endforeach;?>
</select>
<input type="hidden" name="<?php echo 'model'.($i+1).'[id]'?>" value="0"/>
etc....
But I have been unsuccessful.
This is how the arrays are created in the backend.
public function getOptions()
{
$modelLabels = array('car' => __('Age'),
'color'=> __('Color'),
'fuel_type'=> __('Fuel Type'),
'transmission'=> __('Transmission'));
$tmpModelSettings = $this->list_columns();
unset($tmpModelSettings['id'], $tmpModelSettings['name']);
$modelSettings = array();
foreach($tmpModelSettings as $key=>$value)
{
$modelSettings[$key]['options'] = $value['options'];
$modelSettings[$key]['label'] = $modelLabels[$key];
}
return $modelSettings;
}
Sorry, I am new to this - and the PHP documentation did not help me to sufficiently understand code this complex (for me anyway :) )

Answer 1

Your attempt doesn't make much sense (why are you trying to iterate over a key reference?) You should access the particular array element within the $modelSettings array using the key reference. Then you can access the options element in that array subsequently and foreach over them.
<select name="model4[car]" >
<?php foreach($modelSettings['car']['options'] as $value):?>
<option value="<?php echo $value?>"><?php echo ucfirst($value);?></option>
<?php endforeach;?>
</select>
<input type="hidden" name="<?php echo 'model'.($i+1).'[id]'?>" value="0"/>
