php array and returning a default value?

Question

Here is my code:

<div class="search-menu">
  <div class="btn-group fc">
    <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
      <?php
        $currencies = explode(',', hana_get_opt('_cc'));
        foreach ($currencies as $currency) {
          if ($currency == get_option('woocommerce_currency')){
            echo $currency;
            break;
          }else{
            echo "Select Currency";
            break;
          }
        }
      ?>
      <span class="caret"></span>
    </a>
    <ul class="dropdown-menu currency_switcher">
      <?php
        foreach ($currencies as $currency) {
          if ($currency == get_option('woocommerce_currency'))
            echo '<li><a href="#" class="reset default" data-currencycode="' . $currency . '">' . $currency . '</a></li>';
          else
            echo '<li><a href="#" data-currencycode="' . $currency . '">' . $currency . '</a></li>';
        }
      ?>
    </ul>
  </div>
</div>

Which works great it returns a list of my currencies and updates the page accordingly, I have just on question if the user has yet to set a value I would like it to say either select currency or just apply the first option from my hana_get_opt('_cc') array as the default. Here is the html generated code:

<div class="btn-group fc">
                        <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">undefined<span class="caret"></span></a>
                        <ul class="dropdown-menu currency_switcher">
  <li><a href="#" class="reset default active" data-currencycode="SEK">SEK</a></li>
  <li><a href="#" data-currencycode="EUR">EUR</a></li>                                
                        </ul>
                    </div>

I am no php coder and much appreciate any help provided Chris

   if(get_option('woocommerce_currency')==' ')
    {
        $currencies = explode(',', hana_get_opt('_cc'));
          foreach ($currencies as $currency) 
                {

                 if $currency == get_option('woocommerce_currency'){
                     {
                     echo $currency;
                     break;
                       }
                              else{
                                        echo "Select Currency";
                                        break;
                                    }
                 }
    }

    else
    {   
      echo "Select Currency";
       $currencies = explode(',', hana_get_opt('_cc'));
     $currency=$currencies [0];
    }

based on the assumption that get_option('woocommerce_currency') would return null if no currency is selected

<div class="search-menu">
<div class="btn-group fc">
<a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
  <?php
    $currencies = explode(',', hana_get_opt('_cc'));
    $currentCurrency = get_option('woocommerce_currency')
    if ($currentCurrency === false) {
        echo "select currency";
    }
    else{
        echo $currentCurrency;
    }
  ?>
  <span class="caret"></span>
</a>
<ul class="dropdown-menu currency_switcher">
  <?php
    foreach ($currencies as $currency) {
      if ($currency == $currentCurrency)
        echo '<li><a href="#" class="reset default" data-currencycode="' . $currency . '">' . $currency . '</a></li>';
      else
        echo '<li><a href="#" data-currencycode="' . $currency . '">' . $currency . '</a></li>';
    }
  ?>
</ul>

replace the if clause if ( $currentCurrency != null ) with whatever applies, if get_option('woocommerce_currency') returns anything other as null if not yet set

actually like this it still doesn't echo select currency if no currency has been designated in the drop down

MatthiasLaug Over a year ago

what does get_option('woocommerce_currency') return, if nothing has been set before?

MatthiasLaug Over a year ago

according to wordpress documentation get_option returns false codex.wordpress.org/Function_Reference/get_option . I altered my answer. That should work

vimes1984 Over a year ago

it still returns undefined as the first option in the drop down followed by the currencies.

MatthiasLaug Over a year ago

undefined sounds to me like a javascript error. Could you add the HTML code generate between the ul with the class dropdown-menu. I think there is one element in the currencies array, that should not be there.
