我要顯示所有的代碼操作頁面上選中的「天」複選框：

<?php 
    foreach($day as $k) 
    { 
     echo $k.","; 
    } 
?>

HTML表單和操作頁面的模板頁面的wordpress。但它不起作用。我已經寫了這段代碼。

你有沒有

你提交表單嗎？顯示完整的表單？ – Rikesh 2013-05-14 11:10:32

我通過提交表單來完成提交按鈕。它工作很酷 – 2013-05-14 11:12:12

這可以幫助你：

<form name="search_field" id="search_field" action="formpage.php" method="post" > 
    <ul> 
    <li><input type="checkbox" name="day[]" value="mon"/>Monday</li> 
    <li><input type="checkbox" name="day[]" value="tue"/>Tueday</li> 
       <li><input type="checkbox" name="day[]" value="wed"/>Wednesday</li> 
       <li><input type="checkbox" name="day[]" value="thr"/>Thursday</li> 
       <li><input type="checkbox" name="day[]" value="fri"/>Friday</li> 
       <li><input type="checkbox" name="day[]" value="sat"/>Saturday</li> 
       <li><input type="checkbox" name="day[]" value="sun"/>Sunday</li> 
    </ul> 
    <input type="submit" id="submit" name="submit" /> 
    </form>

你可以從這個工作的結果（爲了您更好的瞭解）：

<form name="search_field" id="search_field" action="formpage.php" method="post" > 
<?php if(!$_POST == ''){ ?> 
<ul> 
<li><input type="checkbox" <?php if(in_array("mon", $_POST['day'])) {?> checked="checked"<?php } ?> name="day[]" value="mon"/>Monday</li> 
<li><input type="checkbox" <?php if(in_array("tue", $_POST['day'])) {?> checked="checked"<?php } ?> name="day[]" value="tue"/>Tueday</li> 
      <li><input type="checkbox" <?php if(in_array("wed", $_POST['day'])) {?> checked="checked"<?php } ?> name="day[]" value="wed"/>Wednesday</li> 
      <li><input type="checkbox" <?php if(in_array("thr", $_POST['day'])) {?> checked="checked"<?php } ?> name="day[]" value="thr"/>Thursday</li> 
      <li><input type="checkbox" <?php if(in_array("fri", $_POST['day'])) {?> checked="checked"<?php } ?> name="day[]" value="fri"/>Friday</li> 
      <li><input type="checkbox" <?php if(in_array("sat", $_POST['day'])) {?> checked="checked"<?php } ?> name="day[]" value="sat"/>Saturday</li> 
      <li><input type="checkbox" <?php if(in_array("sun", $_POST['day'])) {?> checked="checked"<?php } ?> name="day[]" value="sun"/>Sunday</li> 
</ul> 
<input type="submit" id="submit" name="submit" /> 
</form> 
<?php 
print_r($_POST); 
?> 
<?php } else { ?> 


<form name="search_field" id="search_field" action="formpage.php" method="post" > 
<ul> 
<li><input type="checkbox" name="day[]" value="mon"/>Monday</li> 
<li><input type="checkbox" name="day[]" value="tue"/>Tueday</li> 
      <li><input type="checkbox" name="day[]" value="wed"/>Wednesday</li> 
      <li><input type="checkbox" name="day[]" value="thr"/>Thursday</li> 
      <li><input type="checkbox" name="day[]" value="fri"/>Friday</li> 
      <li><input type="checkbox" name="day[]" value="sat"/>Saturday</li> 
      <li><input type="checkbox" name="day[]" value="sun"/>Sunday</li> 
</ul> 
<input type="submit" id="submit" name="submit" /> 
</form> 



<?php } ?>

剛創建的文件formpage.php，粘貼上面的代碼並檢查結果。

它將與wordpress一起工作嗎？我的表單是在wordpress中。 – 2013-05-14 13:44:57

試試這個，

<form name="frmli" action="" method="post"><ul> 
<li><input type="checkbox" name="day[]" value="mon"/>Monday</li> 
      <li><input type="checkbox" name="day[]" value="tue"/>Tueday</li> 
      <li><input type="checkbox" name="day[]" value="wed"/>Wednesday</li> 
      <li><input type="checkbox" name="day[]" value="thr"/>Thursday</li> 
      <li><input type="checkbox" name="day[]" value="fri"/>Friday</li> 
      <li><input type="checkbox" name="day[]" value="sat"/>Saturday</li> 
      <li><input type="checkbox" name="day[]" value="sun"/>Sunday</li> 
      <li><input type="submit" name="submit" value="submit"/></li> 
</ul> 

</form> 
<?php 
if(isset($_POST['submit'])){ 
foreach($_POST['day'] as $day) 
{ 
echo $day." "; 
} 
} 
?>

我也試過這個也不行！ – 2013-05-14 11:15:49

我檢查了它的工作，你是否添加了提交按鈕和表單？ – 2013-05-14 11:19:40

請確保您有表單標籤設置是這樣的：method="post"。也首先檢查是否已設置POST['day']。在這種情況下我使用了count（）。我添加了if else語句，以便如果您的$_POST['day']爲空，您至少會迴應它爲空。

<form name="frmli" action="" method="POST"> 
<ul> 
    <li><input type="checkbox" name="day[]" value="mon"/>Monday</li> 
    <li><input type="checkbox" name="day[]" value="tue"/>Tueday</li> 
    <li><input type="checkbox" name="day[]" value="wed"/>Wednesday</li> 
    <li><input type="checkbox" name="day[]" value="thr"/>Thursday</li> 
    <li><input type="checkbox" name="day[]" value="fri"/>Friday</li> 
    <li><input type="checkbox" name="day[]" value="sat"/>Saturday</li> 
    <li><input type="checkbox" name="day[]" value="sun"/>Sunday</li> 
    <input type="submit" value="submit" name="submit" /> 
</ul> 
</form> 
<?php 

if(empty($_POST['day'])){ 
    echo "none of the boxes were checked"; 
}else{ 
    $N = count($_POST['day']); 
    echo("You selected $N door(s): "); 
    for($i=0; $i < $N; $i++){ 
     echo($_POST['day'][$i] . " "); 
    } 
} 
?>

試試這段代碼，並告訴我它是否能解決問題，如果不是，錯誤會怎麼說？ – 2013-05-14 11:31:02

當你第一次加載頁面，沒有什麼是在你的$ _POST ['day']數組中，你的代碼會有一個錯誤，因爲它是空的，但你試圖通過循環來回顯它。您需要首先檢查代碼是否爲空。除此之外。一定要添加表單標籤（關閉表單標籤以及）和提交按鈕。 – 2013-05-14 11:34:38

它已經解決了。 – 2013-05-15 09:11:59
