Data Not Showing Up From A For Loop - php

Question

I am making a product recommender in my shopping cart, something similar to when you go to the grocery store and pickup candy as an impulse.
It looks like below. When I click on the dropdown menu, it does not dropdown with the data I am looking for.
I am using the following code that I would think would input this data:
<?php foreach($Fluoros['Fluoro'] as $Fluoro) {
echo $Fluoro['Fluoro'], '<br>';
}
?>
<select title="Add Fluoro To Your Cart" id="<?php echo $Fluoro['Description']; ?>" class="selectpicker white-drop crimp-part" data-width="auto">
<select title="Select Fluoro" id="<?php echo $Fluoros['Product']; ?>" class="selectpicker white-drop crimp-part" data-width="auto">
<?php foreach($Fluoros['Product'] as $Fluoro){
echo '<option ' . 'value = ' . $Fluoro['Fluoro'] . ' </option>';
}
?>
</select> ```

The data is being pulled in my "Cart " class. The Select statement below works and brings the correct results
```php
public function fluoroCart() {
$getFluoroProducts = $this->_db->query("SELECT i.Part_Number, i.Description
FROM Inventory i
INNER JOIN Product_Details pd on pd.Part_Number = i.Part_Number
WHERE pd.Category_ID = 15");
$fluoroProducts = $this->_db->results();
foreach($fluoroProducts as $Fluoro){
$Flouros [] = array( 'Fluoro'=>$Fluoro->Part_Number, 'Description'=>$Fluoro->Description);
}
}```

Answer 1

In HTML, select option values need to be surrounded by quotes. Also, in addition to indicating a value, you need to put some text between the opening and closing option tags for it to actually show up in the menu.
<select>
<option value="some value">Some Value Text</option>
</select>
You need to modify your PHP like this
echo '<option value = "' . $Fluoro['Fluoro'] . '">'.$Fluoro['Fluoro'].' </option>';
