Question

在完成任务时，我得到了以下要求。

在for循环中，我必须在db中插入数据。我在带有双引号的字符串中进行SQL查询。我必须在$_POST[]

中连接计数器变量

for($k=1;$k<=$total_questions;$k++)
  {
      $sql_insert_survey_question ="insert into survey_questions_options  (question_detail,option_1) values ('".$_POST['survey_que\"$k\"']."','".$_POST['survey_que\"$k\"_option1']."')
      $res_insert_que1=$obj->insert($sql_insert_survey_question);
  }

请提出一些想法。

Answer 1

$_POST['name'].$k

你可以在php

中连接这样的变量

Answer 2

像这样编辑：

for($k=1;$k<=$total_questions;$k++)
{
    $survey_que         =   $_POST['survey_que'.$k];
    $survey_que_option  =   $_POST['survey_que'.$k.'_option1'];
    $sql_insert_survey_question ="insert into survey_questions_options  (question_detail,option_1) values ('".$survey_que."','".$survey_que_option."')";  
    $res_insert_que1=$obj->insert($sql_insert_survey_question);
}

Answer 3

怎么样：

for($k=1;$k<=$total_questions;$k++)
{
  //store them in a temp variable , so it's easy for me to read
  $value1 = $_POST['survey_que' . $k];
  $value2 = $_POST['survey_que' . $k . '_option1'];

  $sql_insert_survey_question ="insert into survey_questions_options  (question_detail,option_1) values ('$value1' , '$value2')";

  $res_insert_que1=$obj->insert($sql_insert_survey_question);
}

Answer 4

for($k=1;$k<=$total_questions;$k++)
  {
    $question = $_POST['survey_que'.$k];
    $answer = $_POST['survey_que'.$k.'_option1'];
      $sql_insert_survey_question ="insert into survey_questions_options  (question_detail,option_1) values ('".$question."','".$answer."')";
      $res_insert_que1=$obj->insert($sql_insert_survey_question);
  }

Answer 5

for($k=1;$k<=$total_questions;$k++)
 {
    $firstValueToInsert = mysql_real_escape_string($_POST['survey_que'.$k]);
    $secondValueToInsert = mysql_real_escape_string$_POST['survey_que'.$k.'_option1']);
    $sql_insert_survey_question ="insert into survey_questions_options  (question_detail,option_1) values ('$firstValueToInsert','$secondValueToInsert')";
    $res_insert_que1=$obj->insert($sql_insert_survey_question);
}

Answer 6

这将有助于您动态插入n个产品..

    $loopLength=$_POST['ProudctSize'];

            for ($i=1; $i <=$loopLength; $i++) 
          {
            $productid=$_POST['P'.$i];
            $quatity=$_POST['Q'.$i];
            $rate=$_POST['R'.$i];

           $Insert=mysql_query("INSERT INTO saledisplay ( `saleid`, `productid`, `quantity`, `rate`) 
            VALUES('$oid','$productid','$quatity','$rate')");
    }

将变量连接到$ _POST []
