Question

我创建了一个联系表单，但它不起作用，我不知道为什么。我的代码出了什么问题？这是警告消息：警告：mail（）期望参数1为字符串，给定数组。我尝试使用localhost的测试邮件服务器工具，我尝试了一切，但没有任何反应。如果我没有弄错的话，警告信息显示$ adminemail有问题。使用var_dump它看起来像这样：数组（大小= 1）＆＃39; i_email＆＃39; =＆GT; string＆＃39; myemail@gmail.com' （长度= 20）

<?php
if (isset($_POST['ok'])) {
    $name           = mysql_real_escape_string(ucwords(strtolower(strip_tags(trim($_POST['name'])))));
    $email      = mysql_real_escape_string(strtolower(strip_tags(trim($_POST['email']))));
    $tel        = mysql_real_escape_string(strtolower(strip_tags(trim($_POST['tel']))));
    $subject    = mysql_real_escape_string(ucfirst(strtolower(strip_tags(trim($_POST['subject'])))));
    $message    = mysql_real_escape_string(strtolower(strip_tags(trim($_POST['message']))));
    $captcha = $_POST['captcha'];

    if (strlen($name) < 5)
        $hibak[] = "Wrong name!";

正如错误所说 - mail（）函数的第一个参数应该是字符串而不是数组。请改用：

mail($adminemail['i_email'], $subject, $level, $fejresz);

这是因为mysql_fetch_assoc（）获取一个数组（线索在函数名中：assoc是关联数组的缩写）：

$adminemail=mysql_fetch_assoc($eredmeny);

您需要使用var_dump（）时可以看到的索引从该数组中获取字符串，这可能也是您的字段名称：

$adminemail['i_email']
