My question is how do I call input value of user selected which has show by php code from another php.

Normal simple way we get the input this way

 $calendar_id_val = $_GET['calendar_id'];

and now it is not working:

For example Show.php, I have one form which show the values from Database and show the result with php variable with While Loop.

<input name="calendar_id" value="<?php echo $calendar_id;?>">

and when user is submit that form I will carry these user selected value and perform insert.php

What is the type of your form.get or post..??Can you show the html..?? – User016 Aug 5 at 6:30
your form looks like this <form action="insert.php" method="get"> or <form action="insert.php" method="post"> ? if get is used in your form then you should use $_GET in insert page, if you used the post in your form then yous should use the $_POST variables in insert.php – sudhakar Aug 5 at 7:08

While you are doing echo in the input use echo $calendar_id_val

You should use form like,

<form action="insert.php" method="get">
  <input type="text" name="calendar_id" value="<?php echo $calendar_id;?>"/>
  <input type="submit" name="submit_id" value="Insert"/>
</form>

Insert.php

echo $calendar_id_val = $_GET['calendar_id'];

my form function is using <form action="insert.php" method="get"> and I type same way as echo $calendar_id_val = $_GET['calendar_id']; the result is not shown – ahkeno Aug 5 at 6:33
Try print_r($_REQUSET), before echoing, also check whether or not it goes on insert.php – Rohan Kumar Aug 5 at 6:35

Does this answer your question?

<form action="insert.php" method="GET">
    <input name="calendar_id" value="<?php echo $calendar_id;?>">
</form>

If you want to redirect the user back to show.php, add this to the end of your insert.php script

header('Location: show.php');
exit();

I suggest $_POST var like this:

<form action="insert.php" method="POST">
  <input type="text" name="calendar_id" value="<?php echo $calendar_id;?>" />
  <input type="submit" name="submit" value="Submit" />
</form>

insert.php file:

echo $calendar_id = $_POST['calendar_id'];
