2 つのページがあり、一方は POST を介して他方に値を渡します。値は、選択アクションの 2 ページ目に表示されません。入力テキストボックスはその値を渡します。以下の両方のページを含めました

先頭ページ： 

mysql_connect("localhost","root","") or die("Unable to connect");
    mysql_select_db("testsite");

$sql = "SELECT state FROM states";
$result = mysql_query($sql);

$sqldegrees = "SELECT degree FROM degrees";
$resultdegrees = mysql_query($sqldegrees);

$sqlschools = "SELECT school FROM schools";
$resultschools = mysql_query($sqlschools);


echo "<html>";
echo "<head>";
echo "<link rel='stylesheet' type='text/css' href='styles.css'/>";
echo "</head>";
echo "<body>";
echo "<h3>Education</h3>";

選択した名前を変更する必要があります-

echo "<select state='state'>";
echo "<select school='school'>";
echo "<select degree='degrees'>";

に

echo "<select name='state'>";
echo "<select name='school'>";
echo "<select name='degrees'>";

また

$degree = $_POST['degree'];

が欠けてsいますdegrees

$degree = $_POST['degrees'];

nameのような選択ボックスに与えます

echo "<select name='degree'>";
echo "<select name='school'>";

そして、あなたはPOST好きな方法でそれらを得ることができます

$degree = $_POST['degree'];
$school = $_POST['school'];
