所有我想做的事是每個<span class="srch-val'>是每個「S-RCH-VAL」下課後添加一個數字，所以S-RCH-VAL-1，S-RCH-VAL-2等..

「每個」是什麼？ – bfavaretto 2012-03-26 15:40:33

你能舉一個你想要的輸出的例子嗎？很明顯，for循環會打印10次相同的東西，因爲$ value不會改變。 – flo 2012-03-26 15:42:42

您的意思是免費設置？ – 2012-03-26 15:43:04

你有你的foreach循環中的額外的循環。刪除這個循環，直接在foreach循環中執行echo，每次使用時都增加$i。

像這樣：

$i = 1; 
while ($query->have_posts()) 
{ 
    $query->the_post(); 
    if ($keys = get_post_custom_keys()) 
    { 
     echo "<div class='clearfix card-prod ".($i==0?'first':'')."'><span class='card-title'>"; 
     echo the_title(); 
     echo "</span>"; 

     foreach ((array) $keys as $key) 
     { 
      $keyt = trim($key); 
      if ('_' == $keyt{0} || 'pricing' == $keyt || 'vehicleType' == $keyt || 'coverageRegion' == $keyt || 'locationType' == $keyt) 
       continue; 
      $values = array_map('trim', get_post_custom_values($key)); 
      $value = implode($values,', '); 

      echo '<span class="srch-val-'.$i.'">'.apply_filters(" $value\n", $value)."</span>"; 
      $i++; // move the incrementer here so that you only increment when you actually use it. 
     } 

     echo "\n"; echo '<img src="wp-content/themes/cafc/images/top-choice.jpg" alt="Top Choice" class="topchoice">';echo '<img src="wp-content/themes/cafc/images/cards/dummy.png" />';  echo the_excerpt()."</div>"; 
    } 
}

您在創建一個變量你的foreach循環的開始（比如$counter == 1;）

比你的for循環應該是：

for($i = $counter; $i <= $counter+10; $i++){ 
    //do your span-class thing here 
}

，並在foreach循環結束做到：$counter += 10;
