我正在使用传递给另一个 php 文件的 URL 值。但是,每次我尝试将name变量的值与下面的普通变量结合使用时,PHP都不会读取它!
global $counterforlist;
$counterforlist= 0;
echo "<form method=\"POST\" action=\" ".htmlspecialchars($_SERVER['PHP_SELF'])."\" > ";
echo "<table>";
echo "<tr><td>ID:</td><td>Company Name</td><td>Date for Service</td><td>Edit</td><td>Delete</td></tr>";
while ($row = mysql_fetch_array($result)){
$counterforlist = $counterforlist +1;
echo "<td><input type= 'text' name = 'jobrequestnumber$counterforlist' value =".$row['jobrequestnumber']."></td>" ;
echo "<td><input type= 'text' name = 'requestingcompany$counterforlist' value =".$row['requestingcompany']."></td>" ;
echo "<td><input type= 'text' name = 'dateforService$counterforlist' value =".$row['dateforService']."></td>" ;
echo "<td><a href=\"update_request.php?jobrequestnumber{$counterforlist}={$row['jobrequestnumber']}&requestingcompany{$counterforlist}={$row['requestingcompany']}&dateforService{$counterforlist}={$row['dateforService']}&{$counterforlist}={$counterforlist}\">Update</a></td>";
echo "<td><a href='delete.php?jobrequestnumber=".$row['jobrequestnumber']."'>Delete</a></td>"; //too
echo "</tr>";
<?php include('update_request.php');?>
这是在 update_request 中调用这些值的另一个 php 文件:
<?php
global $counterforlist;
$jobrequestnumber=$_GET["jobrequestnumber"."$counterforlist"];
$requestingcompany=$_GET["requestingcompany"."$counterforlist"];
$dateforService=$_GET["dateforService"."$counterforlist"];
$required_array=array($jobrequestnumber,$requestingcompany,$dateforService);
$errors = array();
$errors = array_merge($errors, check_required_fields($required_array, $_POST));
if (empty($errors)){
// Database submission only proceeds if there were NO errors.
$query = "UPDATE jobrequest SET
requestingcompany = '{$requestingcompany}',
dateforService = {$dateforService}
WHERE jobrequestnumber ={$jobrequestnumber}";
echo $jobrequestnumber;
$result = mysql_query($query);
错误信息:
注意:未定义索引:第 7 行 C:\xampp\htdocs\xampp\capstone\update_request.php 中的 jobrequestnumber
注意:未定义索引:第 8 行 C:\xampp\htdocs\xampp\capstone\update_request.php 中的 requestingcompany
注意:未定义索引:第 9 行 C:\xampp\htdocs\xampp\capstone\update_request.php 中的 dateforService
如果我要再次声明变量,它将不会从以前的 php 页面读取值。你能帮我弄清楚我错过了什么吗?
