PHP：在電子郵件中顯示覆選框數組

Question

問：如何在我的電子郵件中顯示選定的複選框？

我創建了一個調查（http://www.hello-rio.com/surveyonshoes/），我試圖讓我選中的複選框在提交表單時顯示在我的電子郵件中。我是一個完整的小白，當談到這一點，任何幫助將不勝感激

我的繼承人HTML示例代碼複選框（index.html中）：

<label for="colors">What colors do you own? (check all that apply)</label> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="black">black </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="brown">brown </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="beige">beige </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="white">white </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="gold">gold </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="silver">silver </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="red">red </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="blue">blue </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="yellow">yellow </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="green">green </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="orange">orange </div> 
<div class="twocol"><input type="checkbox" name="color_flats[]" value="purple">purple </div><br> 
<label for="others">Others</label> 
<input type="text" name="color_flats[]" class="others" />

     <?php echo $myError; ?> 

    </body> 
    </html> 
<?php 
exit(); 
} 
?> 

我已經試過各種像破滅的代碼，if語句，的foreach等。不能似乎得到它的權利......

Answer 1

$color_flats = check_input(implode("," , $_POST['color_flats'])); 

$message = "... 

FLATS 
Pairs: $pairs_flats pairs 
Color: $color_flats 


..."; 

Answer 2

由於$color_flats是一個數組，你需要循環每個

foreach($color_flats as $whatever){ 
    echo $whatever; 
} 

，或者你可以爆它使一個和唯一的字符串：

echo implode(',', $color_flats); 

---

<?php 

# Default Vars 
$_color_flats = ''; 
if(isset($color_flats) === TRUE){ 
    # Is Array ? 
    if(is_array($color_flats) === TRUE){ 
     # Count 
     $c = count($color_flats); 

     # Loop 
     for($i=0; $i < $c; $i++){ 
      $_color_flats.= (isset($color_flats[$i]) === TRUE ? $color_flats[$i] : '').($i == ($c-1) ? '' : ($i == $c-2 ? ' and ' : ', ')); 
     } 
    } 
} 

echo $_color_flats; 

?>
