Question

我创建了一个HTML表单，我也编写了PHP脚本来连接数据库。如果我在表单中输入数据并在表单中点击UPDATE按钮，则显示错误如下，

<form action="process.php" method="Post"/>
<style>
p{
    float:left;
}
</style>
<fieldset>
    <legend align="center"><FONT color=default>Enter information Of SO's</legend>

</fieldset>
<div style="text-align:center"> 
<button action= "process.php" method="post" >
   <img alt="ok" src=
   "http://www.blueprintcss.org/blueprint/plugins/buttons/icons/tick.png" /> 
   UPDATE
  </button>


</form>

上述脚本保存在“process.html”

中

现在低于PHP脚本。

<?php
  define('DB_NAME','ProcessTrackingSystem');
  define('DB_USER','root');
  define('DB_PASSWORD','');
  define('DB_HOST','localhost');

 $link=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD);

if(!$link){

 die('couldnot connect:'.mysql_error());
}

  $db_selected=mysql_select_db(DB_NAME,$link);

    if(!$db_selected){
 die('cannot use'.DB_NAME.':'.mysql_error());
}

$value1 =$_POST['SO_ID'];
$value2 =$_POST['No.of samples'];
$value3 =$_POST['Sample name'];
$value4 =$_POST['Client name'];
$value5 =$_POST['Institution'];
$value6 =$_POST['Run number '];
$value7 =$_POST['Obtained reads'];
$value8 =$_POST['Re run Info'];
$value9 =$_POST['Total reads'];
$value10 =$_POST['Run date'];
$value11 =$_POST['Raw data location'];
$value12 =$_POST['Analyst'];
$value13 =$_POST['Mentor'];
$value14 =$_POST['Analysis start date'];
$value15 =$_POST['Analysis end date'];
$value16 =$_POST['Report location'];


$sql="INSERT INTO ProcessDetails (SO_ID, No.of_samples, Sample_name, Client_name, Institution,  Run_number, Obtained_reads, Re_run_Info, Total_reads, Run_date, Raw_data_location, Analyst, Mentor, Analysis_start_date, Analysis_end_date, Report_location) VALUES ('$value1', '$value2', '$value3', '$value4', '$value5','$value6', '$value7', '$value8', '$value9', '$value10','$value11', '$value12', '$value13', '$value14', '$value15','$value16')";

if(!mysql_query($sql)){
 die('error:'.mysql_error());
}

header('Location:process.html');


mysql_close();
?>

现在，如果我将数据输入到html表单中，则显示错误“错误：'字段列表'中的未知列'No.of_samples'”。任何人帮助我解决这个错误并获得所需的输出提前谢谢....

Answer 1

假设您的表中存在var obj = {}; var id = obj.id; //global object $.when(callone(obj)).then(calltwo(id),function(data) { });列，请在查询中引用带反引号（`）的名称：

function callone(requiredData)
{
 var d = new $.Deferred();
 var ajaxCall1 =   $.ajax({
            type:"POST",
            url: 'AB/',
            data: requiredData, 
            success: function(data) {

               //return data to the callee?

                d.resolve(p_obj);
                //set ID on the object
                obj.id = data.id;
                return obj;

            },
            error: function(jqXHR, textStatus, errorThrown) {
                alert(textStatus + ': ' + errorThrown);
            },
            always: function(data)  {  }
        });

}

function calltwo(id from callback one)
{



}

此外，您可能希望查看SQL注入安全风险，并使用未弃用的No.of_samples函数而不是已弃用的$sql="INSERT INTO ProcessDetails (SO_ID, `No.of_samples`, Sample_name, Client_name, Institution, Run_number, Obtained_reads, Re_run_Info, Total_reads, Run_date, Raw_data_location, Analyst, Mentor, Analysis_start_date, Analysis_end_date, Report_location) VALUES ('$value1', '$value2', '$value3', '$value4', '$value5','$value6', '$value7', '$value8', '$value9', '$value10','$value11', '$value12', '$value13', '$value14', '$value15','$value16')";函数。

Answer 2

您要插入不存在的 No.of_samples 列
