Question

你能看到我出现意外T_ELSE错误的原因吗？我必须是瞎子..

<?php
//Check if form was submitted
if(isset($_POST['submit']))
{   
    //Form was submitted.
    if($_POST['paypalemail'] != '');
    {
        //An email was submitted.
    } 
    else
        {
            //There was nothing in the field. Tell them.
            echo "<script language=\"javascript\">alert('The field was left empty. Please insert your PayPal email address and try again.');</script>";
        }
} 
?>

Answer 1

你有一个;在if之后。只需删除它就可以了......;）

if($_POST['paypalemail'] != ''); //<-- Remove this ;

Answer 2

请从

更改脚本

if($_POST['paypalemail'] != '');
{
     //An email was submitted.
}

到

if($_POST['paypalemail'] != '') 
{
    //An email was submitted.
}

您在if循环结束时输入了半冒号。请删除它。

Answer 3

您必须删除第6行的;，如下所示

if($_POST['paypalemail'] != '')
    {
        //An email was submitted.
    }

Answer 4

你的if

末尾有一个半冒号

if($_POST['paypalemail'] != ''); <---

语法错误，意外的T_ELSE
