无法在php中编码和解码网址

Question

I have created a form and passing dynamic information to the next page through URL.

edit_user.php

<form class="w3-container " action='edit_action.php?edit_id=<?php echo $edit_id ?>' method='post' name="form"  id="form-e" role="form">

URL view: http://localhost/gst_work/bank/edit_user.php?edit_id=64

I'm trying to encode Url by urlencode() function to secure data

below code

<form class="w3-container " action='urlencode(edit_action.php?edit_id=<?php echo $edit_id); ?>' method='post' name="form"  id="form-e" role="form">

this return semicolon error every time.

i also want to get this url value in next page ie edit_action.php page. how this can be achieved with decodeurl() function, right now i'm directly using $_GET['edit_id'] method.

And what can be different ways for handling and securing URL data in php apart from encodeurl or session ?

Answer 1

Your syntax is wrong. This is the correct syntax

<form class="w3-container " action='edit_action.php?edit_id=<?= urlencode($edit_id); ?>' method='post' name="form"  id="form-e" role="form">

urlencode is a PHP function and should be within the PHP tags.

To access the edit_id parameter in edit_action.php , use a filtering function like filter_input() and do avoid accessing superglobal arrays like $_GET and $_POST directly.

In your case, filter_input(INPUT_POST, 'edit_id'); since you have the form method set as post.

Answer 2

为什么要编码整个url，只需要编码要传递的值

 <form class="w3-container " action='edit_action.php?edit_id=<?php echo urlencode($edit_id); ?>' method='post' name="form"  id="form-e" role="form">
