HTML和PHP下拉菜单

Question

It's actually an API integration with the server. Here's PHP code:

if(isset($_POST['generate'])) 
{
    require_once dirname(__FILE__) . '/GetResponseAPI.class.php';
    $api = new GetResponse($aid);
    $campaigns   = (array)$api->getCampaigns();
    $campaignIDs = array_keys($campaigns);
    $campaign    = $api->getCampaignByID($campaignIDs[0]);
    var_dump($campaigns, $campaign);
}

Here's the HTML code for the dropdown menu:

<input type="submit" value="Generate" name="Generate" id="Generate"/>
        </br>
        <select name="Campaign" id="Campaign">
        <option value="Option1"><?php echo $campaign;?></option>
        <option value="Option2"><?php echo $campaignIDs;?></option>
        <option value="Option3"><?php echo $campaigns;?></option>
        </select>

I'm actually looking for those 2 to communicate . Example , when user enter their API and hits generate. I want the dropdown to list down the possible campaign .

Thanks in advance for the help.

Answer 1

<input type="submit" value="Generate" name="Generate" id="Generate"/>
    </br>
    <select name="Campaign" id="Campaign">

Answer 2

You need to loop through Campaign, Provided you need to build a campaign array containing its ID and campaign name , if required

<input type="submit" value="Generate" name="Generate" id="Generate"/>
        </br>
        <select name="Campaign" id="Campaign">
<?php foreach ( $campaign as $campaignID => $value ) { ?>
        <option value="<?php echo $campaignID;?>"><?php echo $value;?></option>    
<?php } ?>
 </select>

Answer 3

<?php foreach ( $campaign as $campaignID => $value ) { ?>
    <option value="<?php echo $campaignID;?>"><?php echo $value;?></option>
