如何通过URL传递作为参数传递的PHP值并将其显示在HTML页面中以传递给另一个PHP文件

Question

I have html file where am using php code to display a value which is passed in url for example:

My variable value which is passed through url is "WORKSHOP" and variable name is "eventName"

Which is called in php page using php like as follows:

 <form action="reg_event_validate.php" method="post" id="htmlform" name="htmlform">
    <table  height="80% style="margin-top: 25px; margin-bottom: 60px; background-color:#D9E2F1; border-radius: 5px;" width="650px" align="center">
    <tbody>
    <tr>
    <th colspan="2">
    <?php
    // The value of the variable name is found
    echo "<h3>Event Registration : " . $_GET["name"] . "</h3>";
    ?> 
    </th>

Now i would like to pass that name(eg: WORKSHOP) value to reg_event_validation.php. How to go about. Please suggest some solution.

Answer 1

Try to pass the value using a hidden input field like :

<input type="hidden" name="hiddenval" value="<?php echo $_GET["name"]; ?>"

and try to access this in form action page like

echo $_POST['hiddenval'];

Answer 2

Use input type hidden

<input type='hidden' name='eventName' value='<?php echo $_GET["name"]; ?>' />

OR , Append as Query String

action="reg_event_validate.php?eventName=<?php echo $_GET["name"]; ?>"

Answer 3

You can do it in two ways. Add a hidden input.

<input type="hidden" name="workshop" value="some_value" />

Or you can append to action in form

<form method="get" action="reg_event_validation.php?workshop=somevalue" name="form">
....
