Form data not inserting in Wordpress database even though hard coded data gets inserted

150 Views Asked by At

I'm trying to build a form in Wordpress and inserting data from the form into the database. When I use hard coded data it works fine but if I change that to use variables from the form it is not inserting data at all. Any help would be much appreciated.

    <?php
/*
Template Name: My Form Page
*/
?>
<?php
//user posted variables
$name = $_POST['message_name'];
$email = $_POST['message_email'];
$message = $_POST['message_text'];
$human = $_POST['message_human'];
$selectedFood  = 'None';
if(isset($_POST['selectedFood']) && is_array($_POST['selectedFood']) && count($_POST['selectedFood']) > 0){
    $selectedFood = implode(', ', $_POST['selectedFood']);
}
 //establish connection
if(empty($errorMessage)) 
        {
            $db = mysql_connect("localhost","xxx","xxx");
            if(!$db) die("Error connecting to MySQL database.");
            mysql_select_db("xxx" ,$db);
            $sql = "INSERT INTO wp_picnic_guest (name, yourname, moviename) VALUES ($name, $email, $message)"; 
            mysql_query($sql);


        }
function PrepSQL($value)
    {
        // Stripslashes
        if(get_magic_quotes_gpc()) 
        {
            $value = stripslashes($value);
        }

        // Quote
        $value = "'" . mysql_real_escape_string($value) . "'";

        return($value);
    }


  //response generation function
  $response = "";
   //function to generate response
  function my_contact_form_generate_response($type, $message){
     global $response;

    if($type == "success") $response = "<div class='success'>{$message}</div>";

    else $response = "<div class='error'>{$message}</div>";

  }
    //response messages
$not_human       = "Human verification incorrect.";
$missing_content = "Please supply all information.";
$email_invalid   = "Email Address Invalid.";
$message_unsent  = "Message was not sent. Try Again.";
$message_sent    = "Thanks! Your message has been sent.";

Try wordpress default insert function for inserting values.

    <?php

$name = $_POST['message_name'];
$email = $_POST['message_email'];

    $selectedFood = implode(', ', $_POST['selectedFood']);
}
 //establish connection
if(empty($errorMessage)) 
        {
            global $wpdb;

Firstly there is no needs for connecting database.It's already connected. So remove code lines for connecting database.

Try with

$sql = "INSERT INTO wp_picnic_guest (name, yourname, moviename) VALUES ('$name', '$email', '$message')";
