PHP表格处理从维数组

Question

我有以下功能，

<pre> 
public function getFree($cp) { 
      global $glb_con; 

      try { 
       $sql = "SELECT p.ID, w.ID, p.fname, p.lname, w.desc FROM weight w 
       INNER JOIN comp t ON w.wcl = t.cmp AND w.wc = t.cm 
       INNER JOIN pers b ON w.ID = b.ID_l 
       INNER JOIN pn p ON b.ID = p.ID 
       AND t.cp=:cp group"; 

       $query = $glb_connection->prepare($sql); 
       $query->bindValue(':cp',$cp); 
       $query->execute(); 
       $wes = $query->fetchAll(); 

       // First array Generated from sql1 query 
        $newCorr = array(); 
       foreach ($wes as $option) { 
        $wclID = $option['desc']; 
        $nameF = $option['fname']; 
        $nameL = $option['lname']; 
        $id = $option['ID']; 
        $newCorr[$wclID][$id] = $nameL." ".$nameF; 
       } 

       $sql2 = "SELECT p.ID, e.enre w.ID, p.fname, p.lname, w.desc FROM weight w 
       INNER JOIN comp t ON w.wcl = t.cmp AND w.wc = t.cm 
       INNER JOIN pers b ON w.ID = b.ID_l 
       INNER JOIN pn p ON b.ID = p.ID 
       INNER JOIN t_ent e ON e.ID = p.ID 
       AND t.cp=:cp group"; 

       $query = $glb_connection->prepare($sql2); 
       $query->bindValue(':ID_cmp',$ID_cmp); 
       $query->execute(); 
       $wes1 = $query->fetchAll(); 

       //the second array from sql2 query 
        $newCorrAc = array(); 
       foreach ($wes1 as $option) { 
        $wc = $option['desc']; 
        $ent = $option['enre']; 
        $nameF = $option['fname']; 
        $nameL = $option['lname']; 
        $id = $option['ID']; 
        $newCorrAc [$wc] [$id] [$ent]= $nameL." ".$nameF; 
       } 

      //the form will generate after here here 
       $html_form = ''; 

       if(count($newCorr) == 0){ 

        $html_form .= '<p>'.boz(_('Not Found!')).'</p>'; 
       } else {  

        $html_form .= '<form id="checkEnt" name="checkEnt" method="post" action="r.php?cp=<?=$cp?>">'; 
        $html_form .= '<input type="hidden" value="checkEntrance" name="ent">'; 
        $html_form .= '<table class="table zebra-striped table-bordered table-striped span8">'; 
        $html_form .= '<tbody>'; 

        foreach ($newCorr as $orgKey => $list) { 
         $html_form .= '<tr><td width="5%">'; 
         $html_form .= '<h5>'.$orgKey.'kg</h5>'; 
         $html_form .= '</td> 
         <td width="10%"> 
         <label class="control-label" for="inputWei">Boxer</label>'; 
         $html_form .= '<select class="input-xlarge" id="input" name="drop[0][]">'; 
         $html_form .= '<option value="">Select</option>'; 
         foreach ($list as $key => $value) { 
          $html_form .= '<option value='.$key.'>'.$value.'</option>'; 

         } 
         $html_form .= '</select> 
         </td> 
         <td width="10%"> 
         <label class="control-label" for="inputWei">Res</label> 
         <select class="input-xlarge" name="drop[1][]">'; 
         $html_form .= '<option value="">Select</option> 
         <option value="en">Ent</option> 
         <option value="re">Res</option> 
         </select> 
         </td> 
         </tr>'; 
        } 

        $html_form .= '<tr><td colspan="3"> 
        <div class="modal-footer"> 
        <button type=reset class="btn btn-danger">Reset</button> 
        <button class="btn btn-primary" ID="btnSaveBoxer">Save</button> 
        </div> 
        </td> 
        </tr> 
        </tbody> 
        </table> 
        </form>'; 
       }    
       echo $html_form; 

      } catch(PDOException $e) { 
       addError($e->getMessage(), "MySql-Error", "error"); 
      } 
     } 
</pre> 

它的作用是完全...第一个SQL中使用fetchall方法返回数组，有点变化后的结果会是怎样此...

//首先查询结果阵列检查该线
$ newCorr [$ wclID] [$ ID] = $ NAMEL“” $ NAMEF。;

<pre> 
Array 
(
    [4-6] => Array 
     (
      [87] => haha lala 
     ) 

    [8] => Array 
     (
      [25] => sasa baba 
      [24] => mama fafa 
      [26] => tata lala 
     ) 

    [5] => Array 
     (
      [29] => papa oaoa 
      [27] => laha mana 
      [30] => salam sara 
     ) 

    [2] => Array 
     (
      [33] => tata kaka 
      [32] => lala sasa 
      [31] => Papa lama 
      [34] => wana michel 
     ) 

    [6] => Array 
     (
      [35] => zaza yaya 
      [37] => wana mata 
      [36] => Kaku luba 
     ) 

) 
</pre> 

从上面的代码中可以看到，我生成了从上面的数组填充的下拉表单。

我面临什么问题，客户输入的表单数据后，当我需要填充的形式，因为它是除客户选择，必须选择为默认...

所以，我做了什么是我使用第二个SQL2，它生成以下数组，这个数组正是客户输入的数组。

//第二查询结果数组 $ newCorrAc [$ wc] [$ id] [$ ent] = $ nameL。“”。$ nameF;

<pre> 
Array 
(
    [8] => Array 
     (
      [26] => Array 
       (
        [ent] => tata lala 
       ) 

     ) 

    [2] => Array 
     (
      [31] => Array 
       (
        [res] => papa lama 
       ) 

     ) 

) 
</pre> 

的主要问题是，我怎么能够从他/她先前输入的数据填写表格时，下拉填充一次？

总之，我想要做的是，形式submited，我有链接进行更正。如果点击它应该显示相同的形式，除了之前输入的数据，可以从数据库中获得。

有一些想法吗？

Answer 1

所以我挖通了你的代码。当改变表单生成的循环：

foreach ($list as $key => $value) { 
    $html_form .= '<option value='.$key.'>'.$value.'</option>'; 

} 

这样：

// This will contain selected="selected" html code for your 
// second column dropdown menu. This way seemed to be the clearest for me. 
$typeEntSelected = ''; 
$typeResSelected = ''; 

foreach ($list as $key => $value) { 
    $html_form .= '<option value="'.$key.'"'; 
    if (isset($newCorrAc[$orgKey][$key])) { 
     // Select last user input in Boxer dropdown 
     $html_form .= ' selected="selected"'; 

     $userEntry = $newCorrAc[$orgKey][$key]; 
     if (array_key_exists('ent', $userEntry)) { 
      $typeEntSelected = ' selected="selected"'; 
     } elseif (array_key_exists('res', $userEntry)) { 
      $typeResSelected = ' selected="selected"'; 
     } 
    } 
    $html_form .= '>'.$value.'</option>'; 
} 

和低一点，从这个

$html_form .= '<option value="">Select</option> 
<option value="en">Ent</option> 
<option value="re">Res</option> 
</select> 
</td> 
</tr>'; 

这种改变你的第二个栏下拉代码。 块中的第二行和第三行已更改。

$html_form .= '<option value="">Select</option> 
<option value="en"' . $typeEntSelected . '>Ent</option> 
<option value="re"' . $typeResSelected . '>Res</option> 
</select> 
</td> 
</tr>'; 

它在2千克义和拳字段选择在8千克义和拳字段“塔塔拉拉”和“爸爸喇嘛”。现在它也在第二个字段中选择“ent”和res。其余的是未选中的。这是你以后的行为吗？
