将数组中的值插入SQL查询中

Question

如何从下面的代码中获取数组值？并使用while loop保存非空的数据。 不太确定需要从代码中添加什么。

if(!empty($bookslot['t_deep'])) :
  $tw_deep = 'deep_wrap';
elseif(!empty($bookslot['t_eyelashes'])) :
  $tw_eyelashes = 'eyeLashes_wrap';
elseif(!empty($bookslot['t_holistic'])) :
  $tw_holistic = 'holistic_wrap';
elseif(!empty($bookslot['t_male_nail'])) :
  $tw_male_nail = 'male_nail_wrap';
endif; 

$arr[]  = array($tw_deep, $tw_eyelashes, $tw_holistic, $tw_male_nail);

$db->query("INSERT INTO checked_treatments (treatment_group, id_treatment, id_booking, b_ref) VALUES('$arr', '1','$id_bookslot', '$b_ref')");

在treatment_group中，数组返回Array instead of 'deep_wrap, etch..

期待数据库：

    Array          1   123  abc // <-- result above code
--------------------------------------------------------
    deep_wrap      1   123  abc
    holistic_wrap  2   123  abc

你想做的就是这个（我想）：

$arr  = array($tw_deep, $tw_eyelashes, $tw_holistic, $tw_male_nail);
$arrPlode = implode(', ', $arr);

$db->query("INSERT INTO checked_treatments (treatment_group, id_treatment, id_booking, b_ref)
                  VALUES('$arrPlode', '1','$id_bookslot', '$b_ref')");

这是一个带有查询回应的演示：http://codepad.org/3NgGu1Tm

或

为每个if：

创建一个新查询

if(!empty($bookslot['t_deep'])) {
  $db->query("INSERT INTO checked_treatments (treatment_group, id_treatment, id_booking, b_ref) 
      VALUES('deep_wrap', '1','$id_bookslot', '$b_ref')");
}
if(!empty($bookslot['t_eyelashes'])) {
  $db->query("INSERT INTO checked_treatments (treatment_group, id_treatment, id_booking, b_ref) 
      VALUES('eyeLashes_wrap', '1','$id_bookslot', '$b_ref')");
}
if(!empty($bookslot['t_holistic'])) {
  $db->query("INSERT INTO checked_treatments (treatment_group, id_treatment, id_booking, b_ref) 
      VALUES('holistic_wrap', '1','$id_bookslot', '$b_ref')");
}
if(!empty($bookslot['t_male_nail'])) {
  $db->query("INSERT INTO checked_treatments (treatment_group, id_treatment, id_booking, b_ref) 
      VALUES('male_nail_wrap', '1','$id_bookslot', '$b_ref')");
}

或加强查询：

$concat = array();

if(!empty($bookslot['t_deep'])) {
  $concat[] = "('deep_wrap', '1','$id_bookslot', '$b_ref')";
}
if(!empty($bookslot['t_eyelashes'])) {
  $concat[] = "('eyeLashes_wrap', '1','$id_bookslot', '$b_ref')";
}
if(!empty($bookslot['t_holistic'])) {
  $concat[] = "('holistic_wrap', '1','$id_bookslot', '$b_ref')";
}
if(!empty($bookslot['t_male_nail'])) {
  $concat[] = "('male_nail_wrap', '1','$id_bookslot', '$b_ref')";
}

$db->query(build_insert_query('checked_treatments', 
         'treatment_group, id_treatment, id_booking, b_ref', $concat));


function build_insert_query($table, $cols, $values){
        $return = "INSERT INTO $table ($cols) VALUES";
        $val_length = count($values);
        foreach($values as $key=>$val){
             $return .= $val;
             if($key < ($val_length-1)){ $return .= ", ";  }
        }
        return $return;
}

删除声明中的方括号。你正在制作一个三维数组

$arr  = array($tw_deep, $tw_eyelashes, $tw_holistic, $tw_male_nail);

在您的查询中，您仍然需要取消引用数组以通过指定索引来获取值

$db->query("INSERT INTO checked_treatments (treatment_group, id_treatment, id_booking, b_ref) VALUES('$arr[0]', '1','$id_bookslot', '$b_ref')");

索引为0将返回$tw_deep

的值
