Question

我创建了一个CRON作业，每天早上8点30分运行，以便将报告发送到特定的电子邮件地址。但是，该报告会在输入特定日期的用户之后生效。我想知道如何将$ _post值从开始和结束日期变量更改为'今天'和昨天日期。

这是代码：

session_start();  
$s = $_POST['$yesterday'];  
$e = $_POST['$today'];  
$i = $_SESSION['user'];  
$m = "VACANCY APPLICATIONS REPORT FROM $s TO $e \r\n\r\n";  
$conn = mysqli_connect("");

$em = "email address";  
$vrquery = "SELECT jobid,role,jobtype,vacancyref FROM job ORDER BY jobid";    

$vrresult = mysqli_query($conn, $vrquery);  
while($vrrow=mysqli_fetch_array($vrresult))  
{
$m = $m . $vrrow['vacancyref'] . " " . $vrrow['role'] . " " . $vrrow['jobtype'] .    "\r\n\r\n";  
$vquery = "SELECT cname,ctel,cemail FROM candidatejob,cv,candidate WHERE           jobid=".$vrrow['jobid']." AND candidatejob.cvid=cv.cvid AND cv.cid=candidate.cid AND   cvdate>='$s' AND cvdate<='$e' ORDER BY cname";  
$vresult = mysqli_query($conn, $vquery);  
while($vrow=mysqli_fetch_array($vresult))  
{  
    $m = $m . $vrow['cname'] . " " . $vrow['ctel'] . " " . $vrow['cemail'] .   "\r\n";  
}  
$m = $m . "\r\n\r\n";  
}
$m = $m . "\r\n\r\nALL CANDIDATES SUBMITTING CVs WITHIN DATES\r\n\r\n";
$cvquery = "SELECT cname,ctel,cemail FROM cv,candidate WHERE cv.cid=candidate.cid AND     cvdate>='$s' AND cvdate<='$e' ORDER BY cname";
$cvresult = mysqli_query($conn, $cvquery);
while($cvrow=mysqli_fetch_array($cvresult))
{
    $m = $m . $cvrow['cname'] . " " . $cvrow['ctel'] . " " . $cvrow['cemail'] . "\r\n";
}

$conn->close();  


$headers = "From: no-reply@nortech.org.uk\r\nX-Mailer: PHP/" . phpversion();  
mail($em, " Daily Job Applications Report", $m, $headers);  

?>

cron作业效果很好，但它没有从数据库返回任何结果。我知道连接是正确的，因为它在我的所有页面上都是一样的，它们都可以正常工作。任何人都可以请求帮助，并提供有关为什么不从数据库中提取的建议？

非常感谢

按照上面的编码方式获取今天的日期：

$ e = date（“Y-m-d”）;

获取昨天的日期：

$ s =日期（“Y-m-d”，strtotime（“ - 1天”））;

另外，为什么$ _POST变量名中有美元符号？

php每日电子邮件报告
