复制表格选择框由阵列

Question

最后一个疑问，该foreach不打印在框中

foreach是在代码中间的时候在表外。

上表中的选项值是空的，当打印表格的外部。

$options = array("0.00","0.05","0.10","0.15","0.20","0.25","0.30","0.35","0.40","0.45","0.50","0.55","0.60","0.65","0.70","0.75","0.80","0.85","0.90","0.95","1"); // ◄■■ OPTIONS ARE STATIC (ALWAYS THE SAME). 

     $table = $table."</tr>"; 

     for($i = 0 ; $i <$uCount ; $i++){ 
     $table = $table."<tr><td>".$utilizador[$i]."</td>"; 

     for($j=0;$j<$carCount;$j++){ 
     $val= htmlspecialchars($s2[$j], ENT_HTML5 | ENT_COMPAT, 'UTF-8'); 

     $table = $table."<td>"."<select name=\'corp_resp&{$row_menuid['menuId']}&{$_SESSION['UtilizadorID']}&{$dateTime}&{$toEchosave}'.$val.'_'.$utilizador[$i].'\>"; 
     foreach ($options as $opt) 
     { 
       echo "<option value='$opt'>$opt</option>\n"; 
       echo "</select>\n"."</td>"; 
      } 
     } 
    $table = $table."</tr>"; 
} 
$table = $table."</form>"; 
echo $table;

嘿，你寻找类似this.Please让我知道，如果它帮助。

**在你的代码

更改代码的此块建议编辑

foreach ($options as $opt) 
{ 
    echo "<option value='$opt'>$opt</option>\n"; 
    echo "</select>\n"."</td>"; 
} 

到

foreach ($options as $opt) 
{ 
     $table = $table."<option value='$opt'>$opt</option>\n"; 
} 
$table = $table."</select>\n"."</td>"; 

什么错误，你正在为你打印前的选项字符串即使完整的表格结构已经正确创建。 只需将这些选项添加到表格变量并在每次处理完成后打印。

所以整个代码会是这个样子

$form = "<form onsubmit=\"return validate();\" id=\"teste\" method=\"post\" action=\"teste.php\">"; 
    $table = $form."<table><tr><td>Parametro</td>"; 
    $carCount = count($s2); 
    $uCount = count($utilizador); 
    for($x = 0; $x < $carCount; $x++){ 
     $val= htmlspecialchars($s2[$x], ENT_HTML5 | ENT_COMPAT, 'UTF-8'); 
     $table= $table."<td>".$val."</td>"; 
    } 

    $options = array("0.00","0.05","0.10","0.15","0.20","0.25","0.30","0.35","0.40","0.45","0.50","0.55","0.60","0.65","0.70","0.75","0.80","0.85","0.90","0.95","1"); // ◄■■ OPTIONS ARE STATIC (ALWAYS THE SAME). 

      $table = $table."</tr>"; 

      for($i = 0 ; $i <$uCount ; $i++){ 
      $table = $table."<tr><td>".$utilizador[$i]."</td>"; 

      for($j=0;$j<$carCount;$j++){ 
      $val= htmlspecialchars($s2[$j], ENT_HTML5 | ENT_COMPAT, 'UTF-8'); 

      $table = $table."<td>"."<select name=\'corp_resp&{$row_menuid['menuId']}&{$_SESSION['UtilizadorID']}&{$dateTime}&{$toEchosave}'.$val.'_'.$utilizador[$i].'\>"; 
      foreach ($options as $opt) 
      { 
       $table = $table."<option value='$opt'>$opt</option>\n"; 
      } 
      $table = $table."</select>\n"."</td>"; 
      } 
     $table = $table."</tr>"; 
    } 
    $table = $table."</form>"; 
    echo $table;
