Answer 1

这个评论太长了，因为我试着在那里解释它，但觉得如果在答案中代表它会更好。

Nota：我还将$_FILES['uploadedfile']更改为$_FILES['photo']，因为这会产生错误。

将所有内容从$target = "images/";开始移至echo "<center>Photo ". basename...，然后置于if (isset($_POST['submit'])){下，然后将该条件语句修改为if (isset($_POST['submit']) && !empty($_FILES['photo'])){，您应该好好去。

这是重写：

<?php

/* 
 NEW.PHP

*/

 // creates the new record form
 // since this form is used multiple times in this file, I have made it a function that is easily reusable
 function renderForm($sname, $fname, $error)
 {
 ?>
<?php 
 // if there are any errors, display them
 if ($error != '')
 {
 echo '<div style="padding:4px; border:1px solid red; color:red;">'.$error.'</div>';
 }
 ?>

关闭</form>后，

更改您的代码

<?php 
 }





 // check if the form has been submitted. If it has, start to process the form and save it to the database
 if (isset($_POST['submit']))
 { 
     //This is the directory where images will be saved
$target = "images/";
$target = $target . basename( $_FILES['photo']['name']);

//This gets all the other information from the form

$photo=($_FILES['photo']['name']);
//Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{

//Tells you if its all ok
echo "<center>Photo ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory</center>";
}



 // connect to the database
 include('connect-db.php');
 // get form data, making sure it is valid
 $sname = mysql_real_escape_string(htmlspecialchars($_POST['sname']));
 $fname = mysql_real_escape_string(htmlspecialchars($_POST['fname']));
 $photo = mysql_real_escape_string(htmlspecialchars($_FILES['photo']['name']));

 // check to make sure both fields are entered
 if ($sname == '' )
 {
 // generate error message
 $error = 'ERROR: Please fill in all required fields!';

 // if either field is blank, display the form again
 renderForm($sname, $fname,$error);
 }
 else
 {
 // save the data to the database
  mysql_query("INSERT admission SET sname='$sname', fname='$fname',  photo='$photo'")
 or die(mysql_error()); 
 echo "<center>Admission</center>";
 echo "<center>Successful!</center>";
 // once saved, redirect back to the view page

 }
