变量访问 - MySQL通过PHP无法正常工作

I'm trying to add variables into MySQL. The Column Slot is of type INT and B1 -> B12 is of type VARCHAR(20).

我正在尝试将变量添加到MySQL中。列槽的类型为INT,B1 - > B12的类型为VARCHAR(20)。

$slot1 to $slot4 is a string.(Ex: 4PMTo6PM).The database connects and everything works well when I add hard coded data into the query. However

$ slot1到$ slot4是一个字符串。(例如:4PMTo6PM)。当我将硬编码数据添加到查询中时,数据库连接并且一切正常。然而

However when I pass it over using an NSURL, I dont seem to insert the data. Any help would be appreciated.

但是,当我使用NSURL传递它时,我似乎没有插入数据。任何帮助,将不胜感激。

   <?php
    $DB_hostname = "localhost";
    $DB_Name = "root";
    $DB_pass = "pwd";

    if(isset($_GET["tabName"])){
      $tableName = $_GET["tabName"];
      $slot1 = $_GET["slot1Timing"];
      $slot2 = $_GET["slot2Timing"];
      $slot3 = $_GET["slot3Timing"];
      $slot4 = $_GET["slot4Timing"]; 
     }

     $con = mysql_connect($DB_Hostname,$DB_Name,$DB_pass) or die(mysql_error());


     mysql_select_db("booking", $con);




      mysql_query("INSERT INTO $tableName (Slot,B1,B2,B3,B4,B5,B6,B7,B8,B9,B10,B11,B12)VALUES   
             ('1',$slot1,$slot1,$slot1,$slot1,$slot1,$slot1,$slot1,$slot1,$slot1,$slot1,$slot1,$slot1)");

      mysql_query("INSERT INTO $tableName (Slot,B1, B2,B3,B4,B5,B6,B7,B8,B9,B10,B11,B12)
             VALUES ('2',$slot2,$slot2,$slot2,$slot2,$slot2,$slot2,$slot2,$slot2,$slot2,$slot2,$slot2,$slot2)");

      mysql_query("INSERT INTO $tableName (Slot,B1, B2,B3,B4,B5,B6,B7,B8,B9,B10,B11,B12)
      VALUES ('3',$slot3,$slot3,$slot3,$slot3,$slot3,$slot3,$slot3,$slot3,$slot3,$slot3,$slot3,$slot3)");

      mysql_query("INSERT INTO $tableName (Slot,B1, B2,B3,B4,B5,B6,B7,B8,B9,B10,B11,B12)
       VALUES ('4',$slot4,$slot4,$slot4,$slot4,$slot4,$slot4,$slot4,$slot4,$slot4,$slot4,$slot4,$slot4)");


   mysql_close($con);
   ?>

Any one know what went wrong on the query variables?

任何人都知道查询变量出了什么问题?

2 个解决方案

#1

you have to use ' for string data to insert in query, same goes for all other queries.

您必须使用'用于在查询中插入字符串数据,对于所有其他查询也是如此。

  mysql_query("INSERT INTO $tableName (Slot,B1,B2,B3,B4,B5,B6,B7,B8,B9,B10,B11,B12)VALUES   
         ('1','$slot1','$slot1','$slot1','$slot1','$slot1','$slot1','$slot1','$slot1','$slot1','$slot1','$slot1','$slot1')");

#2

Check the values of $slot1 if it is empty it will not insert it will show error.

检查$ slot1的值,如果它是空的,它将不会插入它将显示错误。

Better put '$slot1', single quotes and try

最好把'$ slot1',单引号和尝试

mysql_query("INSERT INTO $tableName (Slot,B1, B2,B3,B4,B5,B6,B7,B8,B9,B10,B11,B12)
             VALUES ('2','".$slot2."','".$slot2."','".$slot2."','".$slot2."','".$slot2."','".$slot2."','".$slot2."','".$slot2."','".$slot2."','".$slot2."','".$slot2."','".$slot2."')");
