爲什麼我的php循環不工作？

Question

好吧，我有一個PHP變量$的問題，看起來像這樣：

$question['3']['type'] = 'checkbox'; 
$question['3']['desc'] = 'checkbox question'; 
$question['3']['deft'] = '1'; 
$question['3']['opts'] = 'Check Test 1'; 
$question['3']['opts'] = 'Check Test 2'; 

我想要做的是有這是一個調查問題，其中遞減的問題，並OPTS是多個答案。

我現在有這樣的說法：

if ($type == "checkbox") { 
       if (strtolower($deft) == 'y') { $box_value = "1"; $CHECKED = ' CHECKED'; } 
       else { $box_value = "0"; $CHECKED = ''; } 
       print "<input type=\"checkbox\" name=\"$key\" value=\"$box_value\"$CHECKED>\n<br>"; 
     } 

它的工作原理，但它不允許我到包括問題（僅答案）。

我想要做這樣的事情：

if ($type == "checkbox") { 
      print "<br>\n"; 
      $i = 1; 
      foreach ($opts as $opt_key => $opt_value) { 
       if ($deft == $i) {$CHECKED = "checked=\"checked\""; } 
        else { $CHECKED = ''; } 

       print "<input type=\"checkbox\" name=\"$key\" value=\"$opt_value\"$CHECKED> - $opt_value <br>\n"; 
       $i++; 
      } 
     } 

我發現了一個錯誤，因爲我的代碼是蹩腳的。任何人都可以幫助我解決這個代碼？

Answer 1

你需要在打印行$CHECKED之前的剩餘空間？

我假設你正在突破$問題獲得$key,$deft和$opts，因爲你沒有顯示它們的定義位置。是$key應該是$opt_key？

Answer 2

我看到：

$question['3']['opts'] = 'Check Test 1'; 
$question['3']['opts'] = 'Check Test 2'; 

這些都是變量：第二分配覆蓋第一個。

Answer 3

這是一個有點硬，因爲我似乎無法找到你的問題是什麼，但看起來像這樣的代碼：

 
      foreach ($opts as $opt_key => $opt_value) { 
       if ($deft == $i) {$CHECKED = "checked=\"checked\""; } 
        else { $CHECKED = ''; } 

       print "<input type=\"checkbox\" name=\"$key\" value=\"$opt_value\"$CHECKED> - $opt_value <br>\n"; 
       $i++; 
      } 

肯定會引起HTML的問題。

我可以建議對此進行重寫（以及報告是否會影響您的錯誤）。

 
      foreach ($opts as $opt_key => $opt_value) { 
       $CHECKED = $deft == $i ? ' checked="checked"' : ''; 
       print "<input type=\"checkbox\" name=\"$key\" value=\"$opt_value\"$CHECKED> - $opt_value <br>\n"; 
       ++$i; 
      } 

您的代碼的問題是生成的標記看起來像name="key"checked="checked"。應該有一個分開的空白，如name="key" checked="checked"
