Question

以下代码供用户提交电子邮件并压缩此表单。它没有检查数据或将数据插入数据库，也没有正确显示任何错误消息。

<?php

// If the form submit button is set and the email and zip fields are not empty, proceed and process
if( isset( $_POST['submit'] ) && !empty( $_POST['email'] ) && !empty( $_POST['zip'] ) )
{
  // Create variables for form input fields
  $email = $_POST['email'];
  $zip   = $_POST['zip'];

  // Create an array to capture errors
  $errors = array();

  // Create variable to capture success message
  $success = "Thanks for signing up!";

  // Email Validation
  // Check to see if user entered a valid email
  if( !filter_var( $email, FILTER_VALIDATE_EMAIL ) )
  {
    $errors[] = "Invalid email address.";
  }
  // Check email length
  if( strlen( $email ) < 6 )
  {
    $errors[] = "Invalid email address.";
  }
  // Check email length
  if( strlen( $email ) > 50 )
  {
    $errors[] = "Invalid email address.";
  }

  // Zip Code Validation
  // Check to see if zip code is a number
  if( ( !is_numeric( $zip ) || strlen( $zip ) != 5 ) )
  {
    $errors[] = "Invalid zip code.";
  }

  // Include database config file and establish db connection
  require( "includes/config.php" );
  mysql_connect( DB_HOST, DB_USERNAME, DB_PASSWORD ) or die( "Database Connection Error" );
  mysql_select_db( DB_NAME ) or die( "No Database Found" );

  // Check to see if email already exists in database
  $email_check_query     = "SELECT email FROM datingshotgun WHERE email ='$email'";
  $run_email_check_query = mysql_query( $email_check_query );

  // If MySQL query returns any results, user has already signed up and the script will end
  if( mysql_num_rows( $run_email_check_query ) != 0 )
  {
    $errors[] = "Looks like you already signed up...";
  }

  // If there are no errors above run this block of code
  if( count( $errors ) == 0 )
  {
    // Include database config file and establish db connection
    require( "includes/config.php" );
    mysql_connect( DB_HOST, DB_USERNAME, DB_PASSWORD ) or die( "Database Connection Error" );
    mysql_select_db( DB_NAME ) or die( "No Database Found" );

    // Insert email and password into database
    $insert_email_query     = "INSERT INTO datingshotgun (email,zip) VALUES ('$email','$zip')";
    $run_insert_email_query = mysql_query( $insert_email_query );
  }
}

Answer 1

“;”的力量... ：）

更改此行：

$email_check_query     = "SELECT email FROM datingshotgun WHERE email ='$email'";

为：

$email_check_query     = "SELECT email FROM datingshotgun WHERE email ='$email';";

同样适用于：

 $insert_email_query     = "INSERT INTO datingshotgun (email,zip) VALUES ('$email','$zip')";

为：

 $insert_email_query     = "INSERT INTO datingshotgun (email,zip) VALUES ('$email','$zip');";

Answer 2

你知道吗，我想出来......由于某种原因，我的数据库中的id字段没有设置为自动递增。愚蠢的我，这就行了。

似乎无法将这个简单的PHP电子邮件/ zip表单提交给工作
