我有一个由PHP页面处理的HTML表单.我使用mail()完全按照我的需要工作,但遇到了电子邮件部分的问题.发送电子邮件非常不一致,这是不可接受的.我知道mail()只负责过程的一小部分,邮件服务器负责繁重的工作.
我正在尝试PHPMailer作为替代方案.我已经启动并运行,并且能够收到邮件但是有些功能不存在.
在我的表单中,您可以将多个"项目"添加到单个提交中.php应该循环遍历这些项目并为电子邮件中的每个项目创建一个部分.同样,这与mail()一起使用,但并不总是发送.
我想要实现的代码如下.它将发送一封电子邮件,但如果有多个,则不会循环显示表单字段.它只会看到输入的最后一个.
<?php
require 'PHPMailerAutoload.php';
date_default_timezone_set('America/New_York');
$today = date("F j - Y - g:i a");
$mail = new PHPMailer;
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'mail.example.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'mail@example.com'; // SMTP username
$mail->Password = 'password'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable encryption, 'ssl' also accepted
$mail->From = 'mail@example.com';
$mail->FromName = 'From name';
$mail->addAddress('mail@example.com', 'personName'); // …我试图用PHP修改json文件中的数据.我正在使用的代码如下.它能够成功地准备文件内容,并且在foreach循环中它将在if语句中回显.
这很好,if语句现在是硬编码测试.我想要做的是修改各种属性并将其写回文件.这似乎不起作用.当我加载页面,然后刷新以查看是否设置了新值,它只是保持回显相同的值.我在本地下载.json,没有任何改变.
对我做错了什么的想法？
//Get file, decode
$filename = '../json/hartford.json';
$jsonString = file_get_contents($filename);
$data = json_decode($jsonString, true);
foreach ($data['features'] as $key => $segment) {
if ($segment['properties']['UID'] == '25301') {
//echo out properties for testing
echo("KEY: ".$key."<br/>");
echo("UID: ".$segment['properties']['UID']."<br/>");
echo("Full Name: ".$segment['properties']['FULLNAME']."<br/>");
echo("FCC: ".$segment['properties']['FCC']."<br/>");
echo("Render CL: ".$segment['properties']['RENDER_CL']."<br/>");
echo("<hr/>");
//set property to new value.... NOT WORKING?
$segment['properties']['RENDER_CL'] = 111;
}
}
//Test if file is writable to be sure
$writable = ( is_writable($filename) ) ? TRUE : chmod($filename, 0755);
if ( $writable ) …更新先前的问题以获得更好的解释。

我在下面有以下代码。没有对数组的引用，因为我什至无法将其转换为字符串。

The form works great but I am trying to add a delete / remove button. It works except I don't want it to remove the very last item.
