$num2=Mysql_num_rows($result1);
$num3=Mysql_num_fields($result1);
//clinical file ro neshun mide
        if($num2>0)
        {
        echo "<table border=2>";
        for($i=0;$i<$num2;$i++)
        {
        $row=mysql_fetch_row($result1);


        echo"<td>id</td><td>name</td><td>Lastname</td><td>Info</td><td>Sympthoms</td><td>Diagnosis</td>";

        }//if


//showing pharmacies($_POST['ph']):
    $query2="select * from pharmacies";
    $result2=mysql_query($query2);
    $nump=Mysql_num_rows($result2);

    echo "Please Select a Pharmacy:<select ID=2 name='ph'>";
    echo"<option >select please";
    for($i=0;$i<$nump;$i++)
    {

    echo"<option value=$row[1]>$row[1]";
    echo"</option>";

使用相同格式的两个提交按钮

那是你的问题吗？我不确定。如果那么简单！

<form name="xx" method="post">
<input type="submit" name="submit1" value="1" />
<input type="submit" name="submit2" value="2" />
</form>

第1步：在表单中添加具有相同名称的提交按钮。

if($_POST['submit1']=="1")
{
echo "form submited using first submit button";
}

if($_POST['submit2']=="2")
{
echo "form submited using second submit button";
}

第2步：获取不同部分的值。然后你可以为每个按钮做不同的工作

我认为这有帮助！
