【中文标题】SQL查询组特定列值为每个用户发送一封电子邮件【英文标题】:SQL query group specific column value to send single e-mail for each user 【发布时间】:2018-11-15 16:03:39 【问题描述】:我真的需要这方面的帮助,我尝试了几个小时让我的代码正常工作,但我做不到。
我将放置一些代码和输出,以便轻松了解我需要什么以及我得到什么。
正如您在输出中看到的那样,有些用户拥有不止一张卡,而我需要的是,为每个带有卡的用户发送一封电子邮件,例如:
Email #1
To: test1@gmail.com
Text:
Card 1
Email #2
To: test2@gmail.com
Text:
Card 2
Card 3
Email #3
To: test3@gmail.com
Text:
Card 1
Card 2
Card 4
我应该像上面那样发送电子邮件,但我将在下面发布的代码没有这样做,它发送电子邮件但它发送的第一封电子邮件发送到 test1@gmail.com
和 test2@gmail.com
和第二封电子邮件发送到test3@gmai.com
,它为每张卡发送一封电子邮件,而不是一封包含所有客户卡的电子邮件
if (!$stm)
echo "";
else
$last_email = null;
while ($rows = $stm->fetch())
$CPersonUId = isset($rows['PersonUId']) ? $rows['PersonUId'] : NULL;
$CType = isset($rows['CardType']) ? $rows['CardType'] : NULL;
$CNr = isset($rows['CardNr']) ? $rows['CardNr'] : NULL;
$CValFrom = isset($rows['ValidFrom']) ? $rows['ValidFrom'] : NULL;
$CValUntil = isset($rows['ValidUntil']) ? $rows['ValidUntil'] : NULL;
$CLTCCTime = isset($rows['LastTccTime']) ? $rows['LastTccTime'] : NULL;
$CLTPEmail = isset($rows['Email']) ? $rows['Email'] : NULL;
if ($CValUntil != NULL)
$time1 = strtotime($CValUntil);
$mytime1 = date("d/m/Y", $time1);
$CValUntil = $mytime1;
else
$mytime1 = $CValUntil;
if($CType == 6)
$CType = 'Type 1';
elseif($CType == 5)
$CType = 'Type 2';
elseif($CType == 1)
$CType = 'Type 3';
$message = '<html><body>';
$message .= "<p>Cartão nº<b>".$CNr."</b> válido até <b>".$mytime1." Tipo: ".$CType."</b></p>";
$message .= '</body></html>';
$mail->IsSMTP();
$mail->SMTPDebug = 0;
$mail->Host = "test-localhost";
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl';
$mail->Port = "465";
$mail->Username = "admin@gmail.com";
$mail->Password = "passxxxxx";
$mail->SetFrom('admin@gmail.com', 'admin');
$mail->addReplyTo("admin@gmail.com");
$mail->Subject = "Subject";
$mail->AltBody = "Alt";
$mail->MsgHTML($message);
if ( $last_email == null )
$last_email = $CLTPEmail;
if ( $CLTPEmail != $last_email )
//echo $last_email . "</br>";
$mail->addAddress($last_email);
if(!$mail->send())
echo "Mailer Error: " . $mail->ErrorInfo;
else
echo "Message sent!";
$last_email = $CLTPEmail;
echo $last_email."</br>";
【问题讨论】:
听起来你只需要Card
列的逗号分隔结果。 Comma separated results in SQL 的可能重复项?
Didn't you ask something similar already?.
@FunkFortyNiner 我问过它,但关于我的查询,我一直在尝试根据我在该问题上获得的帮助发送电子邮件,但无法正常工作,但他们回答了我的问题问这个问题,因为现在问题有点不同,我提出了一个新问题。
@Larnu,不幸的是,我无法理解如何在我的查询中使用它,但我会继续尝试
@Larnu 顺便说一句,我认为这不是我需要的,因为我不需要发送用逗号分隔的卡片,我需要为每个用户在同一个电子邮件中发送它们。
【参考方案1】:
<?php
function sendCards( $cards, $email )
if( empty( $cards ) || ! $email ) return;
$message = '<html><body>';
$message .= implode('', $cards);
$message .= '</body></html>';
$mail->IsSMTP();
$mail->SMTPDebug = 0;
$mail->Host = "test-localhost";
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl';
$mail->Port = "465";
$mail->Username = "admin@gmail.com";
$mail->Password = "passxxxxx";
$mail->SetFrom('admin@gmail.com', 'admin');
$mail->addReplyTo("admin@gmail.com");
$mail->Subject = "Subject";
$mail->AltBody = "Alt";
$mail->MsgHTML($message);
$mail->addAddress($email);
if(!$mail->send())
echo "Mailer Error: " . $mail->ErrorInfo;
else
echo "Message sent!";
echo $last_email."</br>";
if (!$stm)
echo "";
else
$last_email = null;
$cards = [];
while ($rows = $stm->fetch())
$CLTPEmail = isset($rows['Email']) ? $rows['Email'] : NULL;
if( ! $CLTPEmail ) continue;
if( $last_email !== $CLTPEmail )
sendCards( $cards, $last_email );
$cards = [];
$last_email = $CLTPEmail;
$CPersonUId = isset($rows['PersonUId']) ? $rows['PersonUId'] : NULL;
$CType = isset($rows['CardType']) ? $rows['CardType'] : NULL;
$CNr = isset($rows['CardNr']) ? $rows['CardNr'] : NULL;
$CValFrom = isset($rows['ValidFrom']) ? $rows['ValidFrom'] : NULL;
$CValUntil = isset($rows['ValidUntil']) ? $rows['ValidUntil'] : NULL;
$CLTCCTime = isset($rows['LastTccTime']) ? $rows['LastTccTime'] : NULL;
if ($CValUntil != NULL)
$time1 = strtotime($CValUntil);
$mytime1 = date("d/m/Y", $time1);
$CValUntil = $mytime1;
else
$mytime1 = $CValUntil;
if($CType == 6)
$CType = 'Type 1';
elseif($CType == 5)
$CType = 'Type 2';
elseif($CType == 1)
$CType = 'Type 3';
$cards [] = "<p>Cartão nº<b>".$CNr."</b> válido até <b>".$mytime1." Tipo: ".$CType."</b></p>";
if( ! empty( $cards ))
sendCards( $cards, $last_email )
【讨论】:
我在sendCards( $cards, $last_email )
之后收到以下错误Parse error: syntax error, unexpected '$cards'
就在这里$cards = [];
我做了一些修复。再试一次。
给我这个错误:Parse error: syntax error, unexpected '$cards' (T_VARIABLE) in...
错误在sendCards( $cards, $last_email )
之后的同一行
在sendCards( $cards, $last_email )
之后添加;
