如何在PHP中使用URL中的值

Question

我目前正在制作一个包含4个字段的报告错误表单：

1. 工作ID $jobid
2. 部件ID part_id
3. 机
4. 注意

用户点击与其工作相对应的表格，并将其带到具有变量的网址的新页面。目前所有字段都是空的，但我希望自动填充字段，除了笔记。

当前模型

链接到报告错误表单：

$EM_html = '<a href="/report_error_form.php?JobID='.$jobid.'&Machine=EM&PartID='.$part_id.'">'.$tick.'</a>

报告错误表单：

<form action="" method="post">
        Job Number: <input type="text" value="<?php print ($jobid) ?>" name="jobNum"><br>
        Part Number: <input type="text" value="<?php print ($part_id) ?>" name="partNum"><br>
        Machine Code: <input type="text" name="machCode"><br>
        Note:<br><textarea rows="5" name="note" cols="30" placeholder="More detail... (Is there a way to recreate the error?)"></textarea><br>
        <input type="submit" name="submit" value="Submit">
</form>

Answer 1

您可以使用$_GET

import {Cmomponent, OnInit} from 'angular2/core';
import {ExternalService} from '../externalService';

export class app implements OnInit{
   constructor(myService:ExternalService)
   {
           this.myService=myService;
   }

   ngOnInit(){
     // this.myService.someMethod() 
   }
}

Answer 2

请试试这个

<?php
        $jobid    = @$_REQUEST['JobID'];
        $part_id  = @$_REQUEST['PartID'];
        $machCode = @$_REQUEST['Machine'];
 ?>


    <form action="" method="post">
                Job Number: <input type="text" value="<?php print ($jobid) ?>" name="jobNum"><br>
                Part Number: <input type="text" value="<?php print ($part_id) ?>" name="partNum"><br>
                Machine Code: <input type="text" name="machCode"><br>
                Note:<br><textarea rows="5" name="note" cols="30" placeholder="More detail... (Is there a way to recreate the error?)"></textarea><br>
                <input type="submit" name="submit" value="Submit">
    </form>

Answer 3

您使用$_GET方法，例如此代码

<?php 
$jobid=$part_id=$machine="";
if(isset($_GET['JobID']))
{
    $jobid= $_GET['JobID'];

}
if(isset($_GET['Machine']))
{
    $machine= $_GET['Machine'];

}
if(isset($_GET['PartID']))
{
    $part_id= $_GET['PartID'];

}

Answer 4

 <form action="" method="post">
    <?php $jobNumber = isset($_GET['JobID']) ? $_GET['JobID'] : '' ?>
    Job Number: <input type="text" value="<?php echo jobNumber; ?>" name="jobNum"><br>
    <input type="submit" name="submit" value="Submit">
</form>

Answer 5

尝试使用isset和post方法检查是否声明了变量，并在提交表单

时获取变量数据

<?php
    if(isset($_POST['submit'])){
      $jobid = $_POST['JobID'];
      $part_id = $_POST['PartID'];
      $machCode = $_POST['Machine'];
    }

＆GT;

<form action="" method="post">
     Job Number: <input type="text" value="<?php echo $jobid; ?>" name="jobNum"><br>
     Part Number: <input type="text" value="<?php echo $part_id; ?>" name="partNum"><br>
     Machine Code: <input type="text" name="machCode" value="<?php echo $machCode; ?>"><br>
     Note:<br><textarea rows="5" name="note" cols="30" placeholder="More detail... (Is there a way to recreate the error?)"></textarea><br>
     <input type="submit" name="submit" value="Submit">
</form>


Hope this help
