<?php
 // Default page display
// Connect to the database server
  $dbcnx = @mysql_connect('localh开发者_Python百科ost', 'root', '');
  if (!$dbcnx) {
  die( '<p>Unable to connect to the ' .
  'database server at this time.</p>' );
  }
 // Select the jokes database
 if(! @mysql_select_db('tes') ) {
die( '<p>Unable to locate the joke ' .
'database at this time.</p>' );
 }
// If a joke has been submitted,
// add it to the database.
if (isset($_POST['submit'])) {

$name = $_POST['name'];
$test = $_POST['test'];
$sql = "INSERT INTO details SET
userid='$tes',
name='$name',
test='$test',
date=CURDATE()";
if (@mysql_query($sql)) {
echo('<p>Your joke has been added.</p>');
} else {
 echo('<p>Error adding submitted joke: ' .
 mysql_error() . '</p>');
}
}

 echo('<p> Here are all the jokes in our database: </p>');
 // Request the text of all the jokes
 $result = @mysql_query('SELECT * FROM details where userid="1"');

 if (!$result) {
 die('<p>Error performing query: ' .mysql_error() . '</p>');
   }

 // Display the text of each joke in a paragraph
 while ( $row = mysql_fetch_array($result) ) {

echo('<p><big style="color: rgb(204, 0, 0);">' . $row['name'] . '&nbsp;&nbsp;</big>      <p>');
echo('<div style="text-align: justify;">' . $row['test'] . '&nbsp;&nbsp;</div>');
echo('<p><span style="font-style: italic;">' . $row['date'] . '&nbsp;&nbsp;</span>');


}
 // When clicked, this link will load this page
// with the joke submission form displayed.

?>

Try removing the error control operator, the at sign (@), from the beginning of the database-related functions you are using it with. That suppresses errors from those functions. Also, do you have error reporting on?

ini_set('display_errors',1);
error_reporting(E_ALL);

Are you seeing any text on the page at all? Such as "Here are all the jokes in our database:"

I also see you are using mysql_fetch_array() when you are referring to the $row['name'], $row['test'] as if you were using mysql_fetch_assoc()
