錯誤在PHP

Question

發佈的數據值時，每當我試圖在PHP中我碰到下面的錯誤後的數據值：

Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct() [datetime.--construct]: Failed to parse time string (this wednesday G:i A) at position 16 (:): Unexpected character' in C:\xampp\htdocs\keypad\end.php:14 Stack trace: #0 C:\xampp\htdocs\keypad\end.php(14): DateTime->__construct('this wednesday ...') #1 {main} thrown in C:\xampp\htdocs\keypad\end.php on line 14

這裏是我使用的代碼：

<?php require_once('Connections/rent.php'); ?> 
<?php 

// post 

$id = $_GET['id']; 
$user = $_GET['user']; 
$week = $_GET['week']; 
$pRent = $_GET['pRent']; 
$status = $_GET['status']; 
$rentPaid = $_GET['rentPaid']; 
$result = $_GET['result']; 
$pDate = date("d/m/Y G:i A"); 
$lDate = new DateTime('this wednesday G:i A'); 
$cDate = new DateTime('next tuesday G:i A'); 

// update 

mysql_query("UPDATE rent SET dNo = '$dNo', pdate = '$pDate', pRent = '$result' WHERE rent.id = $id"); 


// if pRent = 0 then set status to clear, colour to #3C0 
if ($pRent == 0) { 
    mysql_query("UPDATE rent SET status = 'clear', colour = '#3C0' WHERE rent.id = $id"); 
} 

// if pRent =! 0 but just paid then set status to paid/not clear, colour to #FF0 
elseif ($pRent =! 0) { 
    mysql_query("UPDATE rent SET status = 'paid', colour = '#3C0' WHERE rent.id = $id"); 
} 

// if status = on holiday, then set status to clear, colour to #3C0 
elseif ($status == 'awaiting') { 
    mysql_query("UPDATE rent SET status = 'awaiting', colour = '#09F' WHERE rent.id = $id"); 
} 

// check all drivers who have/have not paid rent in the past week 
elseif ($lDate < $pDate && $cDate > $pDate) { 
    // date is within desired range 
    mysql_query("UPDATE rent SET status = 'paid', colour = '#3C0'"); 
} else { 
    // date is not within desired range 
    mysql_query("UPDATE rent SET status = 'awaiting', colour = '#09F' WHERE rent.status =! 'not working'"); 
} 
?> 

任何建議？

Answer 1

第14行有問題，$lDate = new DateTime('this wednesday G:i A')無效，請查看Relative DateTime formats以獲取有效的列表。什麼，你需要做的是：

$lDate = new DateTime('this wednesday') 
$lDate->format('G:i A'); 

只是一個建議，前兩行應該是

<?php 
    require_once 'Connections/rent.php'; 

並請考慮使用PDO或其他類似的圖書館，或者至少淨化你的SQL查詢。
