用php，mysql注册表单

Question

In my register form all fields work fine, but the village field return a 0 in the database.

I used ajax and jquery to create a drop list for governorate and district and village.

The first 2 work fine but the village do not insert anything

I didn't know what chunck of code to display to make people understand me so i did display the whole code

This is the code

register.php

<?php require_once('for members/scripts/connect.php'); ?>



<?php
function specializationQuery(){

$specData = mysql_query("SELECT * FROM specialization");

  while($recordJob = mysql_fetch_array($specData)){

     echo'<option value="' . $recordJob['specialization_id'] .  '">' . $recordJob['specialization_name'] . '</option>';

  }


}

 //default value
$message = "Fields Marcked with an [*] are Required";
  $username = "";
  $fname = "";
  $lname = "";
  $specialization = "";
  $email = "";
  $pass1 = "";
  $pass2 = "";
  $governorate="";
  $district = "";
  $village = "";

if(isset($_POST['username'])){
  $username = mysql_real_escape_string($_POST['username']);
  $fname = mysql_real_escape_string($_POST['fname']);
  $lname = mysql_real_escape_string($_POST['lname']);
  $email = mysql_real_escape_string($_POST['email']);

Answer 1

@user2326255 Please check that you choose the village from the dropdown list. In the html you have set 0 option for choose. If the user is not select the village then default value will be send. Change the code

if($village == "")
 {
 $message = $message . "Select Your Village<br />";

 }

To

if($village == '0')
     {
     $message = $message . "Select Your Village<br />";

     }

If user does not select the village then we need to tell the user that please select the village. The above code change will throw the error to the user.
