Question

我有表格，并将数据提交给电子邮件。

提交除提名选项以外的所有内容。

这里添加了我的PHP代码和表单代码。

我想从数据库中获取列表，并将它们放入选择选项中。

提交表格后，应发送选项。

<?php
  if(isset($_POST['submit'])){
  $to = "synergyacademy2014@gmail.com"; // this is your Email address
  $from = $_POST['email']; // this is the sender's Email address
  $first_name = $_POST['first_name'];
  $last_name = $_POST['last_name'];
  $email = $_POST['email'];
  $course = $_POST['course'];
  $subject = "Form submission";
  $subject2 = "Copy of your form submission";
  $message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];
  $message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'] . $course;
  $headers = "From:" . $from;
  $headers2 = "From:" . $to;
  mail($to,$subject,$message,$headers,$course);
  mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
  echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";
}
?>

<form action="" method="post">
  First Name: <input type="text" name="first_name"><br>
  Last Name: <input type="text" name="last_name"><br>
  Email: <input type="text" name="email"><br>
  Course: <select name="course">
    <option>Select Course</option>
    <option value="1">MBA</option>
    <option value="2">MCA</option>
  </select><br>
  Message:<br><textarea rows="5" name="message" cols="30"></textarea><br>
  <input type="submit" name="submit" value="Submit">
</form>

Answer 1

如果要从数据库中获取选项列表，可以尝试使用循环。确保已建立与相应数据库的连接 -

<select name="course">
<?php

$tpl_options = "<option>Select Course</option>";

$query = "SELECT column FROM table [WHERE]";

$courses = mysql_query($query);

$i=1;

while($row = mysql_fetch_array($courses)){

$tpl_options .= "<option value='".$i."'>".$row['column']."</option>";

}

?>

</select>

Answer 2

为了获取表格中的所有行，然后将其分配到<select>选项，我们需要首先确定哪些优秀的API，例如mysqli或PDO，使用。
我们需要首先确定建立与数据库连接所需的数据库和表名。
在下面的示例代码中，我们选择了mysqli_* prepared statement。

代码：

<?php

  /* ESTABLISH FIRST YOUR CONNECTION; REPLACE NECESSARY DATA BELOW */
  $con = new mysqli("YourHost", "YourUsername", "YourPassword", "YourDatabase");
  if ($mysqli->connect_errno) {
      echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
  }

?>

建立连接后，我们现在可以从您的数据库中获取数据。

Course: <select name="course"> <!-- START OF YOUR SELECT -->
  <?php

    /* REPLACE NECESSARY COLUMN NAMES AND TABLE NAME BELOW */
    if($stmt = $con->prepare("SELECT id, course FROM course_table")){ /* PREPARE YOUR QUERY AND CHECK IF YOUR QUERY IS TRUE */
      $stmt->execute(); /* EXECUTE THE QUERY */
      $stmt->bind_result($id,$course); /* BIND THE RESULTS TO THESE VARIABLES */

      while($stmt->fetch()){ /* THEN WE GET ALL THE ROWS BASED FROM THE QUERY WE HAVE CREATED */
        echo '<option value="'.$id.'">'.$course.'</option>'; /* STORE THE VALUES WE HAVE FETCHED TO THIS OPTIONS */
      } /* END OF WHILE LOOP */

      $stmt->close();
    } /* END OF YOUR PREPARED STATEMENT */

  ?>
</select>

PHP表单提交数据，但选择选项除外
