Post form php to another php

Question

I want to publish the search value from index.php to search.php,

index.php

<form action="search.php?val=" method="post">

and search.php

<?php echo $_GET['val']?>

or

<?php echo $_POST['val']?>

I would like to save the value of "val" in the URL, but search.php could not commit the value of "val", which looks like "val =".

Answer 1

Create a text field by name valinside the form in the index file, for example:

<form action="search.php" method="post">
  <input type="text" name="val" value="search string" />
  <!-- more form stuff -->
</form>

And now you can get it as:

<?php echo $_POST['val']?>

If you need this value in the URL, you must change the form method to get, for example:

<form action="search.php" method="get">
  <input type="text" name="val" value="search string" />
  <!-- more form stuff -->
</form>

and then you can get its value on the search page, for example:

<?php echo $_GET['val']?>

action form, val:

<form action="search.php?val=<?php echo $search_string;?>" method="get">
  <!-- more form stuff -->
</form>

, :

<?php echo $_GET['val']?>

</form>

URL-, ,

search.php , $_GET superglobal.

<?php
echo $_GET['val'];
?>

Answer 3

You can use both. If you have <form action = "search.php? Val = ..."> then you can access it in the same way as $ _GET ["val"]. Any other form elements will be displayed in $ _POST [] for your example.

Btw, in cases where the parameter can be represented in different forms, use $ _REQUEST. It captures both GET and POST content.
